reinforcements as greece attempts to stop a surge of migrants crossing from neighbouring turkey. apple agrees to pay up to 500 million dollars to settle claims that it allowed older iphones on purpose to encourage people to buy replacements. hello and welcome. i'm katty kay with christian fraser in washington. doctors now believe the spread of the coronavirus is inevitable and the world health organization has warned that the mortality rate is far higher than the usual rate for seasonal flu. so what are governments to do? the british government's new approach is basically to try to slow the spread until the warmer summer months. it's a four stage approach. contain the outbreak. delay the spread. limit the impact where it's established. research better diagnostics and treatment. the government says it is still in the "contain and research phase" but as things deteriorate it will escalate its response. medical professionals may be given the power to detain people suspected of being infected. retired nhs staff and those on leave may be called "back to duty" to help out. the government is encouraging more working from home to limit contagion. the department for education is setting up a helpline to manage inquiries about the virus. here is the uk health secretary matt hancock. this is a national effort. we need everyone to listen to and act on the official medical advice. we need employers to prioritise the welfare of their staff and the single most important thing that everyone can do, and i make no apologies on repeating this, mr speaker, is to use tissues when you cough or sneeze and wash your hands more often. the world health organization believes that these types of measures in the global battle against the coronavirus are having an impact. but they've warned that the hoarding and misuse of protective equipment is making it harder to stop the spread, putting front line health workers at risk. countries' abilities to respond are being compromised by the increasing disruption to the global supply of personal protective equipment, caused by rising demand, hoarding and misuse. shortages are leaving doctors, nurses and other front line health workers dangerously ill—equipped to care for covid—i9 patients. well, let's talk to larry brilliant — he's an epidemiologist who lead the the world health's 0rganisation effort to succesfully eradicate smallpox, and he's now chair of the skoll global threats fund and joins us now from san francisco. can and joins us now from san francisco. get yourfirst lines can get your first reaction to the lines were getting from the wealth health organisation that the death rate may be a lot higher than we thought it would be? -- the world health organization. i think we should be careful, the death rate will appear to go up and down without any real indicator of what the actual death rate is as we find more and more mild cases, that will increase the denominator and because it takes three weeks or so to become sick enough to be ill and then pass on, we will get some bumps in the death rate. i think we are yet to really know what the death rate will be but we do know one thing, it is well over 20 or 30 times higher than death from influenza. this is a once ina death from influenza. this is a once in a generation disease. can you give us some kind of historical context tha n 7 give us some kind of historical context than? sure, in 1918, the population of 2 billion people in the world between 50 and hundred died. in 2008, when we had h one and one and we thought of it as a mild pandemic, stood between 700000 and i million died. —— still between. perhaps a third of the entire world became sickened by the disease in those cases. if you think of this is a novel disease which means humans have never seen it before and our population is 7.82 billion people, thatis population is 7.82 billion people, that is the number of people who we re that is the number of people who were so that is the number of people who were so perceptible to getting it. i wish that people would think about this, we won't have a vaccine for 12 to 18 months so it is not a sprint. the daily news is not as important as how we prepare to organise society for the next year or year and a half. that is what i liked about the plan that i saw from the uk government. it seems to be adult and rational and looked at what we are going to have to do if, as they say, one out of every five people in the workforce get sick from this disease will stop it will also guide us disease will stop it will also guide us to make sure we find the tests we need so that if somebody has been sick and are immune, they can be certified and able to go back into the workforce. there is the kind of things we have to think about if we are looking at this as a marathon, not as a sprint. talk to me about that test because we have talked about the lack of testing here in the us. but what does it look like? i must say, having covered the story for the last few weeks, i'm still ashamed to say i don't know what i would if i had a dry cough deep in my lungs. what should i do next? i'm embarrassed in behalf of cdc which is usually the gem of all that us government agencies. i think the cuts in government spending for cdc, the and high science inclination of this administration has put cdc on its back foot. —— the anti—science. we will have millions of test kits. they should be inexpensive or free. it shouldn't be such a big production to get a test if you have a cough ora production to get a test if you have a cough or a fever. so what if we are testing more people than have the disease? that is what we do with every test we do in medicine because it is so important to find people who actually have the disease we are looking for. we have done this backwards by restricting it to 200 test kits for the entire state of california. we have put ourselves weeks behind the academic curve. -- the epidemic curve. that is interesting to hear that. weeks behind the curve, we have been talking about the lack of test kits and now the ministration say they think they will have a million test kits out here but think how much time has been lost and we are getting stories of people who have taken the test and getting a bill for $3000 because they don't have health insurance but they're that is going to put more people off getting the test. i was talking to someone yesterday who questioned the wisdom of the president going off to india and we have just had their comment not enough test kits for california where this was emerging for it is interesting that he praises the uk government there because i think having been caught a little cold fitted going on holiday for half term, borisjohnson fitted going on holiday for half term, boris johnson has fitted going on holiday for half term, borisjohnson has really got on top of this because they see the political risk. it is notjust about public health but the economy and slowing it down and getting through the summer months and there is still criticism. it was the president so to see the political risk but is he was focused on the markets aside but not necessarily the side? the long race to chose a democratic nominee to take on donald trump in november — could end today. could. this is super tuesday — the day lots of american democrats go to the polls to pick a candidate. there's a chance we come out of this day with one candidate having an insurmountable lead in the race. at the very least this day has already shaken up the race, forcing some candidates out and caterpulting others to the front of the pack. progressive senator bernie sanders hopes today will confirm him as the undisputed frontrunner. former vice presidentjoe biden believes he can capitalise on recent momentum to become the centrist favourite. and it's mike bloomberg's very first primary test. he has not been on the ballot up until this point. a very big night for mike bloomberg. how does super tuesday work? you win the democratic nomination by winning delegates. it's not about winning states, this is now a game of maths, it's about adding up your delegates to get to the magic number of 1,991. one third of all delegates available are up for grabs today. there are 415 in california. texas has 228 and north carolina has 110. the other states with a lot of delegates — viriginia and massachusetts. under democratic rules, only candidates who get over 15 percent of the vote in either the state or an individual congressional district will win any delegates at all. it's a move designed to weed out weaker candidates. so, let's take a look at who remains in the running. remember a candidate needs 1,991, a majority of delegates, to become the nominee. bernie sanders is currently in the lead with 60, butjoe biden is snapping at his heels with 5a. elizabeth warren is a distant third, and the others have none. on monday pete buttigieg and amy klobuchar pulled out of the race, their delegates will be reassigned, most likely to joe biden. this rally around joe biden ahead of today's vote looks like a concerted effort to stop bernie sanders from getting the nomination. in 2016, the republican establishment failed to stop donald trump becoming the party's nominee because moderate candidates in that race refused to drop out, even though many of them said they were terrified trump couldn't win. you're not the only ones hearing echoes of that very race today. bernie sanders saw last night's endorsements forjoe biden as an establishment coup to prevent him from winning. and let me tell you something, the establishment is getting very, very nervous. cheering look, it is no secret. i mean, the washington post posts 16 articles a day on this, there is a massive effort trying to stop bernie sanders. that is not a secret to anybody in this room. let's cross now to new york where we're joined by democratic strategist capri cafaro. hgppy happy super tuesday. so, are we going to come out of tonight possibly with either a clear nominee 01’ possibly with either a clear nominee or perhaps two people who are going to be and a head—to—head race?” think it is going to be more likely that we are going to see a bernie sanders and joe biden sort of neck and neck going into the rest of the primary contest after super tuesday. about a third of the delegates are on the table for today, 1300 delegates in total it seems are up for grabs. 0ne delegates in total it seems are up for grabs. one thing i think uses important to share with you and the viewers is that a number of these states, particularly places that have a lot of delegates on the table like the state of california, have a early voting which means that a lot of people have already cast their votes. there is about 3.5 million democratic ballots that have already been cast across the country and primary is that i voting today so what does that mean forjoe biden? that means that he may not have the type of momentum to draw upon from the south carolina primary because people already cast their ballot. it will be interesting to see how it turns out. i think that california is definitely an important place to watch because bernie sanders i think will have a lot of momentum there but then you have two other states which are home states of former candidates, elizabeth warren's massachusetts and amy klobuchar‘s state. we saw people turn out in north carolina to early vote. how close to bernie sanders doesjoe biden need to come tonight to call ita biden need to come tonight to call it a good night? i think very close. no matter what i think he is going to spin it and say we are the comeback kid, everyone has us on life support. he has already said things like that. joe biden has not had the financial resources nor the infrastructure in a number of these states in the same level as bernie sanders. so i think he is trying to mitigate expectations and rightfully so mitigate expectations and rightfully so because this is almost a last—ditch pitch which is why i think we saw some of these other centrist candidates so to speak, pete buttigieg and amy klobuchar bow out right before super tuesday, hoping to try and get some of their delegates over potentially to joe biden as they explicitly endorsed him. that would be the assumption. i thinkjoe biden will try to spin it no matter what is a good night but i think unless it is very close and i think unless it is very close and i think within less than 50 delegates between the two, i think it is going to be hard hit for bernie sanders. bernie sanders is going to absolutely say he is ahead and he is the frontrunner. thank you very much for joining the frontrunner. thank you very much forjoining us. so let's get the view now from texas, which is one of the states with the biggest number of delegates. cliff walker is the deputy executive director of the texas democrats, hejoins us now. big question about texas i guess is one of these candidates the person that can flip texas from republican to democratic? well, first, thank you for having me. second, i should note that as the texas democratic party we administer the primaries in the states i'd be cautious not to say anything that might be perceived as advantage in the candidate but i will say that the changes in texas are largely stretchable. we have over 3 million people or approaching that you have registered to vote since 2016. the majority are overwhelmingly majority democratic. there is a clear path for us to win for the ticket as well as flipping oui’ for the ticket as well as flipping our legislative chamber and also picking up a us senate seat. can we talk about michael bloomberg. he spent $400 million, it is a dated driven campaign during delete drilling into the numbers and people say that going back into 2016 the democrats didn't have a very good ground game. that is strength, do you think? i can say that there has clearly been an investment made in the state and it is something we have been able to perceive. i think the public reports showed that there are about 18 offices on the ground, about 180 staff thereabouts i believe but the other candidates are maintaining a presence as well and are ramping up in a major way. the race is quite fluid, i think there has been reference to the fact that as these changes are being made in this dynamic race that many votes are already being cast. we have quite extensive early voting in this state but i can say that they know there are a bunch of people who are looking to see how south carolina fair, waiting to see the final discussion amongst candidates, the final endorsements. we are expecting a very big turnout today that could really go any way. i don't know about super tuesday, it felt to me like a super monday forjoe biden for is that he gets all these endorsements from buttigieg and amy klobuchar and then out pops the former candidates from texas. that isa former candidates from texas. that is a big endorsement and i have been seeing polls today, spot poles of course, but it does seem to have made a difference forjoe biden. what i can say is that it is worth noting that a lot of this happened here in texas and again i want to be cautious not to say anything to appear to advantage any of the candidates but i think it is worth noting that here in this state, we are 38 electrical votes shy of winning in 2016 and the fact that we are now pulling in a single figures, it is clearly the biggest battle ground state. the fact that the...” think we lost that line to texas. you know it is interesting about texas? democrats every cycle so that texas? democrats every cycle so that texasis texas? democrats every cycle so that texas is the state they are going to flip and put it in the blue column. they're not going to do it until they get higher levels of hispanics to turn out and benny standers is going to super tuesday is saying in nevada i got money is turnout. —— bernie sanders. but there they are much more unionised. there's not a guarantee that he can replicate that in texas. what is a good result for biden tonight? it is interesting listening that thatjoe biden has to come within 60 delegates to say that he has had a good night. i have heard other people suggest from the biden side that if we come within 1oo biden side that if we come within 100 hundred and 50 will be happy and stay in the race. it will all depend i think on what happens after super tuesday and weather might be decides, those billions of dollars is going to spend, joe, take them away. and we will be bringing you all the latest on the super tuesday race tonight at 7pm, that's on the bbc news channel and bbc world news , and we'll be bringing you all the results here from midnight. the european union's three most senior figures went to greece's southern border with turkey today with one message to convey — greece's borders are europe's borders and we stand by you. they were there to view the effects of turkey's decision at the end of last week to abandon its 2016 deal with the eu and allow migrants to freely cross into europe. europe's migrant crisis reached its peak in 2015 when almost a million people entered the eu and thousands more drowned trying. now that turkey's borders are essentially open, that crisis threatens to return. let's just remind ourselves of some key events over the past few days. last thursday, at least 33 turkish soldiers were killed by a syrian air strike near idlib, turkey's worst loss in a single attack since the war in syria began. the next day, the turkish government announced it would cease controlling its land and sea borders with europe, saying it could not cope with a new wave of refugees after an escalation of the syrian conflict. by the end of the day on saturday, up to 4000 people had amassed at greece's border with turkey hoping to make the crossing into europe. yesterday, the greek army announced that a military drill with live bullets would be conducted along the entire turkish—greek border. since then, one child has drowned and a syrian migrant has reportedly been shot. jonah fisher is on the greek—turkish border at the kastanies crossing point where the european union leader visited earlier today alongside the greek prime minister. they've just been in that area behind me. that is no man's land leading to turkey and about a kilometre behind me that is where this group of 7000 migrants which have been gathering there over the last few days right up to the fence with the encouragement of turkey and hoping to get through to greece and to europe. so yes, i think the message, the optics if you like from today, will be that these european officials are showing their solidarity with greece. there may be a bit of talk about increased security arrangements, particularly in the aegean sea where we have seen a steady rise in the number of folks attempting to make the crossing from turkey to the greek islands. let's cross to the greek island of lesbos now where our correspondent gabriel gatehouse sent this report. well, what is happening, as you can see, is the police are trying to push everyone away from this port area. there are a couple of hundred migrants and refugees here. some of them possibly some of the newcomers that have come in the past two days but many have been here for months if not years and they are desperate, they have been telling me, to get off this island. i think they thought that there was a chance of a boat to athens and that's when they all came down here but i don't think that has turned out to be the case. now, they are all being pushed on. a little bit earlier, we saw some scuffles and tensions have definitely been rising, notjust in the last few days but in the last month or so between the migrants and refugees and the police on the one hand but also between some local people who have been hosting these people now for five years and for one reason or another, maybe it is the newcomers from turkey, maybe it is something else but things have reached a bit of a tipping point and as i say, tensions are rising and the mood is souring. that was gabriel gatehouse on lesbos. let's take you a bit further south now to the island of samos. here's the times' newspaper turkey correspondent hannah lucinda smith. and when i didn't particularly yesterday, it was announced that they were having an exercise where they were having an exercise where they were having an exercise where they were going to be firing and sending out a warning to everyone on the island to avoid certain places. we don't know whether this is linked to what is happening with the new arrivals coming across the aegean sea but some of those places they are doing a live fire exercises a live fire exercises are places where refugee boats have been coming on in previous days are so obvious that is extra added danger the people trying to make thatjourney but also what we have seen is some footage coming in now and it clear that this is footage that is being shared primarily by the turkish government although it does seem to be genuine footage of the greek coastguard pushing back refugee boats, firing blanks into the water next to them, so it is really clear that the greek authorities are now taking quite a serious measures to really close their borders and to push back anyone who tried to cross them. extraordinary pictures there and we're going to keep an eye on that story with the border with greece. so there is a worldwide effort under way to get people to wash their hands. a p pa re ntly apparently you have to sing god save the queen. i thought it was happy birthday twice but apparently not. idid try i did try this today and got drenched. you prefer happy birthday? yes. for viewers on the bbc news channel and bbc world news, italy continues their struggle to contain the virus — the death toll has risen dramatically over the last 24 hours, and cases of infection continue to grow. and apple's rotten dealfor consumers — the tech giant agrees to set aside half a billion dollars in compensation because of slowing down iphone deliberately. the first few days are brought more sunshine and today was a good day for chasing rainbows. today we will see a break from this —— tomorrow. this card is looming large and it will bring some rain up from the south—west. no great amounts of rain my do. 0ut south—west. no great amounts of rain my do. out of that we have some clearing skies as the showers tend to fade away and with the wind is light it will get cold quickly. towards the south—west wears in the cloud quickening some rain arriving is not as cold here but further north and east there will be more widespread frost, it may be a bit colder than it was last night. a bright and sunny start first thing. this card is going to move its way northwards and it was bringing the rain up in the south—west, pushing it across wales into the south—east of england it was the midlands and some wet weather i think the northern ireland committee. some snow over the hills of wales and by the end of the day perhaps into the peak district as well. further north in scotland some sunshine, she was restricted to the north—west. some showers for south wales, south—west england, after the rain clears away. but rain, rather ragged and patchy will head its way slowly northwards, grinding toa will head its way slowly northwards, grinding to a halt across northern england. ten or 15 millimetres and a bit of snow over the pennines was not that wetter weather easing off later through the night and on thursday morning that there is another area of low pressure as well. keeper close eye on this one which threatens to bring heavy rain through the english channel and perhaps into the far south of england. further north, an improving picture across england after that damp weather overnight and for most cases there will be a little sunshine, showers continuing to run into scotland and northern ireland. again, it isjust into scotland and northern ireland. again, it is just about cold enough to bring wintry of a higher ground stop we lose one area of rain, an area of low pressure during the evening and then in time for friday we have this weather front approaching from the atlantic. it is approaching from the atlantic. it is a weak weather front, no approaching from the atlantic. it is a weak weatherfront, no big temperature contrast either side of it it is a narrowband of patchy rain with some snow over the hills further north. it may well be that the showers behind that are a little bit more potent and heavier and again wintry over the higher ground temperatures are stuck at around seven to 9 degrees for top into the weekend, and whilst we don't have a named storm, it will be turning windier with some more rain on the way on saturday to be replaced by sunshine and showers on sunday. this is beyond 100 days. i'm katty kay with christian fraser in washington. our top stories... borisjohnson lays out measures to manage a coronavirus epidemic in the uk, with a worst case scenario of up to a fifth of the workforce off sick. it's a big night for the democrats as the presidential candidates vie for wins across 14 states super tuesday states. the candidates are the same, their policies are the same, and the voters are the same. so did anything change in israeli's third election within a year? apple agrees to pay up to $500 million to settle claims that it has slowdown older iphones on purpose to encourage people to buy emplacements. —— replacements. the new coronavirus figures from northern italy are alarming. 0vernight the death toll rose from 52 people to 79. and there are 500 new cases. italy's outbreak came to light 12 days ago and is focused mainly on two redzones in the north of the country, one in the region of lombardy and another smaller one in the neighbouring region of veneto. now, italy is considering setting up another quarantine near the northern city of bergamo. and alarmingly, cases have now been confirmed in all but one of the country's 20 regions. we're joined now from milan, by our correspondent bethany bell. the by our correspondent bethany bell. suspicion was 1 widespread the suspicion was that it was more widespread because people can be asymptomatic in carrying disease but not showing any signs of it was not the italians say they have been doing extensive testing of people. whether or not they have been showing symptoms and still, although there have been these cases reported throughout the country, the hotspots still seem to be these areas in northern italy. particularly in law considering setting up a possible quarantine near the town of bergamo and lombardy. there seems to have been this concentration in the north of the country with these worrying figures and people are really wondering, it is interesting when you talk to people, they are worried about the virus but also about the effect of the shutdowns and the people not coming to italy on their economy and some people say they are not sure whether to worry more about health or economy. what is the government plan? the uk government has just released its four—point proposalfor has just released its four—point proposal for trying to delay the spread of the disease until the warmer weather kicks in. has the italian government come up with our son that plan or is it about quarantine? —— similar plan. son that plan or is it about quarantine? -- similar plan. the measure so for having quite drastic in terms of trying to stop people from coming out of these towns but some epidemiologists saying with the virus may have been present in natalie before the first cases started emerging in these northern regions. they are still struggling to figure it exactly how some of the lines of contagion may have gone and at the moment, they say that they are working very, very hard to try and prevent it from spreading more. people here of course nervous with thisjump people here of course nervous with this jump on the people here of course nervous with thisjump on the number of people here of course nervous with this jump on the number of deaths and the number of infections. they say, we are told that the next few days will be crucial to see how successful this country can be trying to stop the spread. a lovely background. thank you very much. we have heard there has been a briton infected by the coronavirus in tenerife and there is no one confirmed death in spain which again lends itself to this theory that the virus is spreading, containment looks to be a losing battle. it will not be long, we don't think, before governments in europe start trying to delay the spread of the virus. we keep getting told that you have to wash your hands. it is one of the keys to stopping the spread. i'm joined now by kate 0rkin — research fellow in behavioural science at oxford university. is this the kind of incident or crisis or whatever you want to call it that gets generally people to act in the common good? absolutely. behavioural science tells us that when we strongly and normatively appealfor people when we strongly and normatively appeal for people to do the right thing, overwhelmingly the well. and people are most strongly influenced by the behaviour of those around them so if they see people sticking to public health advice they are more likely to do it as well. what about the issue of quarantine because obviously millions of people in china have been locked out. we have never had people in northern italy who had to be in self quarantine. any western societies that are pretty individualistic, people will buy into self quarantine for 14 days if it comes to that and ifa for 14 days if it comes to that and if a lot of people need to? , i think if people see that there is an overwhelming social norm that is really what expected, it is likely that people will stick to it. we have not had a crisis like this in recent times in britain but overwhelmingly, later water crises cities have overwhelmingly pulled together to make sure they do what is on the common good. evidence does suggest that it is likely people will stick to quarantine and in fact in china, a lot of, we think, it has been an authoritarian response would actually, a lot of the time, people have been self imposing the behaviour. not that they have been forced to do it. yet, when the authorities say stop buying hand gel and masks, it is not going to stop you getting the coronavirus. stop stockpiling food in the kitchen, people still do it. why? it is an interesting thing about messaging. we actually have behavioural science evidence that says when you say to people everyone else is doing this bad thing, they think it is ok and then they do it as well. so it is an issue about the messaging. when there was a forest where lots of people removing wouldn't they put up a sign that said lots of people have been removing wood, and there would, more people remove the wood and then they put up the sign that said please don't do the right thing don't remove the wood and then people did the right thing. it is a bit more about appealing to people's betterjudgment bit more about appealing to people's better judgment than saying bit more about appealing to people's betterjudgment than saying this is what everyone is doing. so the government today has said at some point it is an inevitable we will move to the stage where people have to work from home and change their routines. as there something that families can do? can be planned for the week that are coming?” families can do? can be planned for the week that are coming? i think people's initial response has been in some instances to panic buy. it is really important people understand the psychology behind why they are wanting to do that so there is evidence that people panic buy particularly useful things, when they are feeling a lot of control. it is not actually that you need 20 bottles of hand sanitiser but you are trying to do with the psychological need. there are lots of ways that you can feel a little bit more in control of the situation. 0ne bit more in control of the situation. one of them make a specific plan for yourself about how you will stick to the recommended behaviours. it is actually really ha rd to behaviours. it is actually really hard to make sure you are washing your hands on the time. but a lot of evidence says make very specific plan about how you are going to do it, when you are going to do it, who is going to be doing it. the second thing you can do is help family and friends to make those plans and can encourage those around you in the workplace to make those plans and to stick to them. and then you get the good social equilibrium where eve ryo ne good social equilibrium where everyone is sticking to the good behaviours. so there are things that people can do to feel more in control but it is also really important that we interrogate our psychology and our initial instincts quite a lot and understand a little bit about the science of why we're certain things. thank you very much. next time you're in the supermarket and thinking of buying a can of tuna to stock up, going wash your hands instead. iam to stock up, going wash your hands instead. i am watching people like a hawk in the toilets at the moment andi hawk in the toilets at the moment and i am not impressed. we're not doing this well enough. i went to a meeting this morning and people were still shaking hands. men are a lot worse women statistically. does this surprise me? maybe not. with most of the votes counted from israel's third general election in a year, benjamin neta nyahu's party is in the lead, but two seats short of a governing majority. mr netanyahu, who is due in court in two weeks to face corruption charges, claimed victory last night declaring the result to be the biggest win of his life. the bbc‘s anna foster is injerusalem. he is due in court in a few weeks' time that i imagine he will be trying to build this coalition and he only needs one but it is quite an uncertain picture still? it really is. he has a lot to do in the next two weeks or so. it is interesting because the votes are still being counted at the moment, nearly all they are. you were just talking about coronavirus a few minutes ago. we have had an education here in israel and how to vote in the time of coronavirus. they had special polling station set up and what they are doing overnight tonight and into tomorrow is actually counting those votes which have been double bagged and processed by people in full suits, gloves, masks, sent away to be destroyed once they have been counted. there are still 4000 votes to be counted, soldier votes as well. we are not quite at the stage where benjamin neta nyahu well. we are not quite at the stage where benjamin netanyahu can declare victory even though he did that at his party last night. what it is about now is about how healing ghettos extra seats that he needs. it is not as easy as tempting and mk across from another party because if you do that you face sanctions. you can ever be a deputy minister or minister in the government. after this term ends he would not be able to stand again for any parties in it or indeed to form your own youth action so it is difficult for him to do that, difficult for him to persuade people over. there are some names in the frame but he has a lot of work to do if he wants a try and form a government before he goes on trial in two weeks' time. there was nothing about that answer that was nothing about that answer that was not extraordinary. a lot of work to do before he goes on trial and the accounting votes in hazmat suits. thank you very much for linking other stories to today. this is beyond 100 days. still to come, a powerful storm cut through the middle of tennessee. in nashville, buildings were eviscerated. we'll speak with to a politician there about the response. antarctica recorded its highest temperature earlier this month. it reached more than 20 degrees centigrade. it's bad news for the extraordinary marine life that lives in the icy waters of the world's coldest continent. 0ur chief environment correspondent, justin rowlatt, met some of the marine biologists leading research into the impact that the changing antarctic environment is having. antarctica is the most extreme continent on earth. few animals can survive the bitter cold. but one antarctican environment is surprisingly stable — the ocean. but it is cold, minus two celsius. it is the coldest place on earth that marine animals live. like everywhere else in the world, the antarctic environment is changing. in some places, the water is already warming. a huge challenge for animals that have never experienced any change. so, some of the incredible antarctic animals are in this tank. anne todgham is a marine biologist and you have been studying these animals for years. so they have antifreeze proteins inside of them that keep them from freezing. they have different red blood cells that are in fact not red. they have compensated for the cold so they can go about their daily lives and actually thrive in an environment that most animals would find very stressful. the big question for anne is how well these extraordinary creatures will be able to adapt. the results so far are not promising. i'm actually pretty worried. i wish the data was wrong. i wish i didn't have to be worried, but there are lots of things that are going to change in the ocean and these animals are being stressed to their max. you may wonder why we should worry about the fate of a few unusual species, but the scientists here say we should think of what is happening as a warning. if these animals can't survive in ourchanging world, what does that say about our future? justin rowlatt, bbc news, antarctica. at least 22 people have died after two tornadoes ripped through central tennessee. officials say the tornadoes caused widespread damage to buildings in the state's biggest city nashville. neighbourhoods have been plunged into darkness — about 44,000 people have been left without power. let's talk tennessee state senate republican leader jackjohnson who joins us now on the phone. thank you so much forjoining us. commiserations to you and your community. what is a situation at the moment in the nashville area? thank you for having me on your programme. we had a line of severe storms that passed through the middle tennessee area last night. roughly 1am central standard time it produced at least one serious tornado, possibly multiple tornadoes, with winds in excess of 150 mph. that extensive damage in the nashville area blocks from where iam now the nashville area blocks from where i am now in the nashville area blocks from where iam nowina the nashville area blocks from where i am now in a state capital, the tornado continued on the ground for approximately 42 miles, creating significant damage in eastern nashville, continuing —— 32 miles. we have 22 confirmed fatalities, probably in the hundreds of millions of dollars in damage. 0ur governor hasissued of dollars in damage. 0ur governor has issued a state of emergency, president trump is scheduled to visit that it national oh nashville area. thank you for your condolences, it is a tragic scene. these are appalling pictures that we are looking at. a lot of people around the world might not have had an experience or know what a tornado is like and the unpredictable nature of it. can you explain for us what it is like when a tornado warning comes in? it is absolutely terrifying. i have been in areas, i have never been in a direct hit but it isa have never been in a direct hit but it is a terrifying situation and it is something that cannot be predicted with a hurricane or other types of weather phenomenon. a tornado can happen typically in a thunderstorm where you have various wind directions and they can come quickly. what is particularly dangerous with what happened last eight as it happened at roughly 1am in the morning. most people are asleep. silence and warnings went off on cell phones support hopefully most people were able to take shelter but they are very predictable and very dangerous. senatorjackjohnson, thank you very much. take care and we hope everybody gets what they need to recover from that. terrifying. difficult for the people on the ground. how many of us have owned an iphone that over the years has got slower and slower until it becomes unusable. well, here in the united states a number of customers complained that the company was intentionally slowing down its older phones to encourage us to buy new ones. apple strenuously denied these allegations, although it has conceded software it develops can slow the processing power of phones when the battery is low, abruptly shutting them down. recently, they cut the cost of replacing iphone batteries. it didn't prevent the lawsuit thought and now apple has though and now apple has been forced to settle. they have agreed to pay 500 million dollars, to us customers only, not as an admission of wrongdoing or liability but to avoid, they said, costly litigation. lets speak to dan ackerman editor of cnet. tell me bluntly. 0ur apple slowing down the iphones with some of the softwa re down the iphones with some of the software and are they doing it intentionally? i can barely hear you, but it sounded like if you're asking if they were slowing down the iphones intentionally and in a sense they are but not really. what they decided was that these batteries as they get older cannot hold the same amount of charge, therefore it is dangerous or bad for the phone if you keep running really powerful programmes on them and they said we will just ramp down programmes on them and they said we willjust ramp down the maximum output of the battery is a little bit in order to keep the phone safe. what that meant was, sometimes the phone would feel sluggish which apple said was properly better for you in the long run than your phone freaking out and shutting down. that was the intention, not clearly communicated which is really where a lot of people got bothered by it, especially where they said my phone is super sluggish, i need to buy a new 800 900 or $1000 phone. is super sluggish, i need to buy a new 800 900 or $1000 phonem is super sluggish, i need to buy a new 800 900 or $1000 phone. is $500 million effectively and admission of guilt the app part of apple? they say it is not. maybe you went and bought the new phone before apple admitted what background situation was and said we will take your old battery that is kind of worn out and swa p battery that is kind of worn out and swap it for a new battery instead of $79 or so that would normally cost. it is only $20 to change the battery, maybe it should have been free, but 29 seem to be another eve ryo ne free, but 29 seem to be another everyone was happy with so this was their way of making it up to people who feel like they did not get their moneys worth out of the original purchase and may be people who went to buy a new phone although it works out to maybe $25 a person if you are lucky. i'm not sure that is going to matter to everyone after four or five years. $25 is peanuts. i can imaginea five years. $25 is peanuts. i can imagine a slew of court cases in europe because there has been a legal victory here. 0bsolescence is a huge issue for companies as we focus on climate change and throwaway culture? i did not quite catch all of that but if you are asking there is a similarfear of catch all of that but if you are asking there is a similar fear of a case like this in europe, i suppose it is not admission of guilt, that is what everyone always says. the judge has to approve it, decided between two parties. frankly, most of the money goes to the lawyers anyway. that is why you can see $25, nearly 35, may less. at the end of the day, none of these class—action suits against companies ever really end up putting more than a few dollars on people's pockets. thank you very much forjoining us and for battling through some of the issues we are having up your. there is a very big air—conditioning unit behind us. and a very helicopter which keeps landing. apologies if you are struggling to heal us. 14 returning now to one of our top stories. 14 states will be voting in the democratic primaries today for super tuesday. one of those states is vermont, where the frontrunner bernie sanders cast his own vote earlier today. jane 0'brien is in vermont, shejoins us now. and exciting night in vermont, one of the earliest results they will get and of the earliest results they will getandi of the earliest results they will get and i suspect we know who will when there? christian, ithink it might be bernie sanders. i think. i think there is a very strong chance for soppy is the only game in town. everyone i spoke to loves bernie sanders, they are voting for him. amy klobuchar and pete buttigieg dropping out of the race is not really affected the result prime at all. although they do like elizabeth warren as well. the problem is that they feel they are second guessing all the time, even bernie sanders supporters are not convinced that he can beat donald trump. it is that they now then decision, you can't go to your gut because you're co nsta ntly to your gut because you're constantly worrying, if i vote for this person are you going to vote for that person? that second—guessing and indecision, you can feel it deep in the heart of bernie sanders country. they know bernie sanders country. they know bernie sanders country. they know bernie sanders very well up there. he has been a congressman and then a senator for many years. are they surprised to see the way in which they have captured attention of young people right across country?” don't think there is much surprise because his disruptive appeal is pretty well—known. he is channelling a lot of millennial likes at the moment, the sense that the american dream is not working out for the next generation. they know that he isa next generation. they know that he is a disrupter and again this was back to the struggle we are seeing within the democratic party. do you wa nt within the democratic party. do you want somebody who will blow up the system and start again? or do you wa nt system and start again? or do you want somebody who can build on the existing system likejoe biden? people who are voting for bernie sanders generally don't like joe biden. they feel he has had a chance, he is done, it is time for somebody new which is hilarious when you think that bernie sanders is 78 but that is how they describe them. ijust but that is how they describe them. i just realised looking but that is how they describe them. ijust realised looking at you, in this snow behind you, i realise we have sent you from new hampshire to vermont. you do know there is a super tuesday race in california and texas? sorry, where is california? california is where it is nice and sunny! but i am assuming the energy bernie sanders has, you go to his rallies, it is like none of the other democratic candidates. do they believe they in the mont it could carry him to the white house? there is something different about this campaign. i think there is the energy, he still has the energy. the rallies that you go to, people are absolutely committed. and i think it is because he has been running this race for five years. don't forget he has in campaigning since 2016 when he lost to hillary clinton. so there is an energy. i think there is also an acknowledgement that, if the party chooses, bernie sanders, there isa party chooses, bernie sanders, there is a risk that they go to far to the left and they will lose the battle ground states, the more moderate voters in the states that the democrats need to win to beat donald trump. and it is still coming back to that central question. do voters go with their heart and bernie sanders has captured hearts. 0r go with their heart and bernie sanders has captured hearts. or do they go with somebody who the absolutely no can beam donald trump and that is still the question nobody can give me a definitive a nswer nobody can give me a definitive answer to. one of the difficulties watching him and joe biden last night and they were on a programme i watched back to back, is bernie sanders has a very practised rhetoric. he has done this, he did in 2060, he knows which to pull and i don't sense when i watchjoe biden that he has the same rhetoric. the issues that really matter to people. would you say that is fair?” issues that really matter to people. would you say that is fair? i think the problem joe biden has had right the problem joe biden has had right the way through is that he has campaigned ona the way through is that he has campaigned on a platform that he is a person to beat donald trump and he was challenged in that assumption by amy klobuchar, pete buttigieg, they did not get the votes they needed to come up to his but the takeaway support from him and in so doing, made it obvious that voters do have a choice about this big question of electability. but there are others voters believe can be donald trump. whereas bernie sanders has very much campaigned on issues like health care, like forgiving student debt. these are issues that appeal to people so they know what they are getting. ok. jane in the snow vermont, having come from the snows of... she does snow. we will put her ona of... she does snow. we will put her on a beach next time to shake up a little bit. and we'll be bringing you all the results here from midnight. and we will be on for hours and hours. join us for that. the first few days of march have brought some much—needed quiet weather. a mixture of sunshine and showers. this picture sums it up quite nicely. a good day for chasing rainbows. we will see outbreak from the sunshine and showers because we look at in the atlantic, this area of cloud living large will bring some rain up from the south—west. no great amount of rain. ahead of that, we have clearing skies, as the showers tend to fade away. with the wind likely to get called quickly towards the south—west and we have seen the cloud thickening, some rain arriving, not as cold here. further north and east, there will be more widespread frost, maybe about colder and last night. a bright and sunny start first thing. this cloud will move north, bringing the rain up pushing across wales and the south—east of england, some wet weather for northern ireland too. by the end of the day, perhaps into the peak district as well. further north in scotland, some sunshine, showers we re in scotland, some sunshine, showers were set to the north—west. some sheriff or south wales, south—west england after the rain clears away. at rain, rather ragged and patchy will head north, grinding to a halt across northern england. 10—15 millimetres, the weather easing off in the night and threw thursday morning. there is any other area of low pressure as well. keep a close eye on this one, threatening to bring some heavy rain through the english channel and perhaps into the far south. further north and improving picture across northern england after that damp weather overnight. for most places, better sunshine and showers continuing to run, just about cold enough for them to be wintry over high ground, especially in the heavier showers. we lose one area of rain and low pressure during the evening in time for friday, we have this weather front approaching from the atlantic but it is a very weak one, no big temperature contrast either side of it so temperature contrast either side of itsoi temperature contrast either side of it so i narrow band of patchy rain with some snow over the hills further north. it may be that the showers behind that are a little bit more potent and again wintry over the high ground stuck at around 7-9d. the high ground stuck at around 7—9d. enter the weekend, whilst we don't have a name of storm it will be turning windy. there are some more rain to be replaced by sunshine and showers on sunday. this is bbc news. the headlines at eight. as the number of of people infected in the uk rises to 51, the prime minister says it's highly likely we will see further infection and has unveiled the government plan to tackle the coronavirus. our plan meets were committed to doing everything possible based on the advice of our world leading
