for russia to "halt its aggression", and accuses the kremlin of waging a disinformation campaign to justify an invasion of ukraine. russia denies it's preparing to carry out false sabotage operations. experts say they're hopeful that efforts to save red squirrels in scotland could be helping native populations recover but warn that measures to control grey squirrels will have to continue for some time. later this hour, on the road with self—driving cars, taking to the track for some autonomous racing, and finding out how and why this car changes colour. we'll get behind the wheel of the future of motoring, in click. borisjohnson must "lead or step aside", senior tory and former minister tobias ellwood has told the bbc. meanwhile labour leader sir keir starmer said it was now in the "national interest" for the prime minister to resign following events in downing street during strict lockdown measures. the moral authority matters in relation to enforcing the covid rules but we've got other massive challenges facing this country. massive challenges. we have a prime minister who is absent, he is literally in hiding at the moment, and unable to lead. and so that is why i have concluded that he has got to go. and of course there's a party advantage in him going, but actually it is now in the national interest that he goes. so it is very important now that the tory party does what it needs to do and gets rid of him. claire pearsall is a conservative councillor in kent, who was formerly a home office special adviser. she spoke earlier to my colleague joanna gosling who started by asking whether she'd had a chance to speak to local residents in her area. i've had a number of conversations this week. the general mood is that people are incredibly angry. they have abided by the rules all the way through and faced some real hardships. but they did it because they were told to, it was the right thing to do, and to protect their family and friends and people in my village. and to see the prime minister's team and the prime minister himself flout those rules has hit very hard. sir keir starmer has said this morning that it is time for borisjohnson to go. he says of course there is a party advantage for labour in him going, but actually says it is now in the national interest that he does. do you think that this does transcend party politics now? yes, i think it does. i know conservative supporters who are equally as angry as those who support the green party or the liberal democrats, for example. so i think this does transcend those kinds of barriers. and colleagues are going to have to work out what it is they want from the prime minister going forward, and that has to happen quickly. what do you think should happen? i think there is more to come out and i think it is not going to be very long before we see yet another revelation, so the prime minister now needs to think very long and hard as to whether he is doing the rightjob for the country, and certainly for the party. do you think he should go? i think it is probably time for him to move on. i think that a number of colleagues now are looking at that as an option. we have seen some very senior tories come out this morning and sayjust that, and i agree with them. earlier i spoke to our political correspondent nick eardley this weekend is quite an important gauge of that for tory mps. they are back in their constituencies, trying to judge the public mood, and from the ones i've been speaking to, it doesn't seem great, quite frankly. a former cabinet minister was saying the story yesterday about the party the night before the duke of edinburgh's funeral made things worse, they thought the reception they were getting was terrible. it is interesting, anotherformer ally of the prime minister, a brexiteer, said they didn't think there was any way the pm could now lead them to the next election. and there is a growing list of things that are being looked at by the senior civil servant sue gray. i suppose the question is whether the mood amongst tory mps starts to harden, whether they feel under more pressure to act, and the labour leader sir kier starmer urging them to do so this morning, saying it would be in the national interest. we are not getting much from number ten. they are saying wait for the investigation to come back. but they must be feeling the heat this morning. this afternoon, rather. yes, how time moves on. what do the next few days look like? i think the start of next week will be important to see exactly how tory mps feel, if they have decided they need to act against the prime minister or not. i should point out there are some allies of borisjohnson saying they think the public is prepared to wait for the investigation to come back before making their minds up. we may get that investigation next week, we don't know for sure, but there have been ministers suggesting it would be soon. and that will be a big moment, because if the senior civil servant looking at this, sue gray, says the prime minister did something wrong, or there was a problem in number ten, or there were other events or that the prime minister was at them, i think it adds more pressure to him. is it guaranteed that borisjohnson goes? absolutely not, because he still has his supporters, those who think he is an electoral asset, there are still a number of measures that would need to be taken, a number of steps gone through for him to be removed from office by the conservative party, but he is under a lot of pressure, more than he has ever been under as prime minister. this inquiry by sue gray, which the government keeps referring to and asking everyone to be patient until those findings are published, that is getting bigger and bigger as more events come to light, it's not her role to be judge and jury on this — it's a fact—finding inquiry. you are totally right. nobody expects her to come back and say that a crime was committed, it's not her remit to judge whether borisjohnson has broken the rules that ministers have to follow, the ministerial code — it is a fact—finding mission. i suspect we'll be poring over the language of it. because if other events are brought to light, if there is a suggestion the prime minister knew about things that could be rule—breaking, or a suggestion he broke the rules himself, i think that would add to the pressure. one senior tory said to me last week if there is a suggestion the prime minister has broken the rules or done something seriously wrong, it could be terminal. joining me now is criminal and human rights barrister kirsty brimelow, who represented a teenager given a £10,000 so—called superfine while there were restrictions on indoor socialising in may last year. thanks forjoining us. these finds have cost some people a huge amount of money. tell us briefly about the circumstances of this one. it of money. tell us briefly about the circumstances of this one.- of money. tell us briefly about the circumstances of this one. it was an 18-year-old — circumstances of this one. it was an 18-year-old young _ circumstances of this one. it was an 18-year-old young man, _ circumstances of this one. it was an 18-year-old young man, his - circumstances of this one. it was an l 18-year-old young man, his parents, 18—year—old young man, his parents, it was actually the bank holiday, the 2nd of may last year, his parents were away for the weekend and he took the opportunity of inviting some friends around for a party, and at that time the restrictions were no more than 30 indoors, and a few more came. the police in the fixed penalty notice thought there were maybe 30—30 indoors and outdoors, potentially there was a defence on the numbers, but the issue was his fixed penalty notice of £10,000, 28 days to pay, and who has that sort of money? 0bviously and who has that sort of money? obviously not him, not his mum and dad. it moved his gran in particular would be drawing out all of her pension in order to pay, because she didn't want to see her grandson thrown off a career he was about to start by potentially not paying. then the only option would have been to have a trial in the magistrates�* court, and then potentially be convicted and get a criminal record. it was a lot of stress for the family, it was merseyside police. i made written representations on a couple of occasions, contacted by telephone the police, we finally got through to somebody who was able to exercise some discretion and they acted sensibly and agreed to withdraw the fixed penalty notice and eventually it was a £200 fixed penalty notice issued, reduced to £100 if paid within seven days, which they did. i £100 if paid within seven days, which they did.— £100 if paid within seven days, which the did. , , ., .,. which they did. i believe you acted on aid. which they did. i believe you acted on paid- yes. _ which they did. i believe you acted on paid. yes, and _ which they did. i believe you acted on paid. yes, and he _ which they did. i believe you acted on paid. yes, and he was - which they did. i believe you acted on paid. yes, and he was one - which they did. i believe you acted on paid. yes, and he was one of. on paid. yes, and he was one of man . on paid. yes, and he was one of many- many _ on paid. yes, and he was one of many. many examples, - on paid. yes, and he was one of many. many examples, at - on paid. yes, and he was one of many. many examples, at the l on paid. yes, and he was one of. many. many examples, at the end on paid. yes, and he was one of- many. many examples, at the end of last year a student at nottingham trent university, at that time you could have no more than six indoors, the end of 2020, no more than six indoors, there were probably about eight, she got a letter threatening prosecution or fixed penalty notice, again representations, so there was again representations, so there was a lot of enforcement in the country and i acted unpaid in these cases but also a lot of my colleagues did, and took on these cases to try to help people. in and took on these cases to try to help maple-— and took on these cases to try to help peeple-_ help people. in light of what we have heard _ help people. in light of what we have heard about _ help people. in light of what we have heard about these - help people. in light of what we have heard about these various| have heard about these various parties happening in downing street, what do you believe should happen to these fixed penalty notices which have been issued?

allegations in relation to covid offences retrospectively, that is generally a sensible approach because the approach is meant to reflect light touch policing but the difficulty is up and down the country we have not seen that approach with members of the public. and there is a heightened responsibility and accountability when we have those people in government who potentially are in breach of the regulations, and certainly there can be no argument they are in breach of the guidance from the evidence we have seen in newspapers. so the met police should be looking at government, investigating, with a view to advising what crimes have potentially been committed. that is a matterfor the potentially been committed. that is a matter for the courts potentially been committed. that is a matterfor the courts if potentially been committed. that is a matter for the courts if they have been committed or not. lawyers for the woman accusing prince andrew of sexual assault are seeking testimony from two people in the uk. meanwhile prince andrew�*s legal team want to question his accuser�*s husband and her psychologist as part of his civil sex case. prince andrew, seen here leaving the windsor estate with sarah ferguson, also argues that ms giuffre "may suffer from false memories". the duke has repeatedly denied claims aganist him. novak djokovic has been detained in australia ahead of a court hearing that will determine whether he can stay in the country. the world men�*s number one tennis player faces deportation after his visa was cancelled for a second time. the australian government has labelled the 34—year—old a threat to public health because he�*s unvaccinated against coronavirus but his lawyers are appealing, describing the decison as irrational. shaimaa khalil has the latest. free the refugee! once again, novak djokovic is in detention, and once again, the world number one is challenging the cancellation of his visa. in court documents which were released today, we learned that the immigration minister made his decision because the player�*s presence in australia may foster anti—vaccination sentiment. the tennis star�*s legal team says the argument was invalid and irrational, and that deporting him would potentially undermine support for the vaccination programme. and while some of djokovic�*s supporters gathered to back him, there has been little sympathy for the tennis player. i do feel that to make a statement that we are sticking by what we have been calling for the last two years, i feel it is best for djokovic to probably sit this one out. i hope that the government and the judges hold their ground and say, you don't want to get a vaccination and you don't want to follow our rules, then you can't come in. when novak djokovic�*s visa was revoked the first time he was held here at this immigration detention hotel. more than a week later, he�*s back. only two days before he is meant to compete in the australian open and defend his title, this is where he will be spending the night, and when he does get out on sunday, it won�*t be to go to practice. he will be in his lawyer�*s office while a court decides his fate. his rival rafael nadal said the grand slam is not just about djokovic. the australian open is much more important than any player so if he is playing, finally, ok, if he�*s not playing, the australian open will be a great tournament with or without him. that is my point of view. sunday�*s court decision is crucial for both sides — the top seed whose chance at a 21st grand slam rides on it, and a government that has been hugely embarrassed by the mishandling of the saga. shaimaa khalil, bbc news, melbourne. tsunami waves a metre high have hit the pacific island nation of tonga, after an underwater volcano erupted for the second time in two days. satellite images show the eruption which was followed by darkened skies as the volcano sent black ash into the air. residents have been

africa cup of nations. england are up against it once again in the final ashes test in hobart — as they look to avoid a 11—0 series defeat. australia scored some vital runs before being dismissed for 303. england�*s reply was just ten balls old when rory burns was run out for a duck, on his recall to the side — opening partner zak crawley, creating some indecision. australia captain pat cummins took four wickets — most importantly, that of his counterpartjoe root, who went lbw for 311. england were five down with just 88 runs on the board, when ben stokes was caught for four. they rallied a little but were all out for 188. they did make some inroads into australia�*s top order before the close, stuart broad dismissing david warner again. marnus labuschagne and usman khawaja were also removed leaving austrailia on 37—3 — 152 runs ahead at stumps. there are six games in rugby union�*s european champions cup wasps, fresh from ending leicester�*s unbeaten run, were first up against

the australian open and says he�*s pleased to be playing at a high level again. to all of you who came out to support tonight, what an amazing atmosphere to play in — thank you. it was so good.

disinformation campaign to destabilise and justify an invasion of ukraine. liz truss wrote on social media that russia must halt its aggression, de—escalate and engage in meaningful talks. it comes after a week of us—russian talks aimed at defusing tensions. russia has amassed tens of thousands of troops on the border with ukraine, prompting invasion fears. thieves are leaving thousands of opened and damaged packages strewn across the railway tracks in east los angeles after looting goods trains passing through. products that are difficult to move or re—sell, or are too cheap, like covid—19 test kits, furniture and televisions, are just dumped on the tracks. the thefts are affecting major us mail order and courier companies like amazon, ups and fedex. james reynolds reports. if you live in los angeles and your package hasn�*t been delivered, you might want to check the rail line in the east of the city. freight trains passing through this area have become an easy target for thieves, who leave evidence of their raids all over the tracks. as trains head into a busyjunction, they often slow down or stop, and looters are ready. theyjump on these trains, these locks that these containers have are really sometimes plastic seals, the locks aren�*t really sturdy strong, you know. they don�*t care if the train is moving or not. theyjump on the train, pop the lock and just start grabbing whatever they see. all of this has accumulated over the last month alone. looters aim for the most valuable items they can find, ripping through packages and avoiding cheaper bulk cargo items like toilet roll. towards the end of last year, more than 90 containers were vandalised every day. thefts peaked around christmas. according to the rail operator union pacific, over the last year looting along the train line in los angeles county has risen by 160%, costing millions of dollars. the thefts have hit major companies, including amazon, ups and fedex. the rail operator says it has now increased security along the line. wildlife experts in scotland are hopeful that progress is being made with efforts to save the native red squirrel from extinction. the introduction of the grey squirrel caused them to disappear from great swathes of the uk. alexandra mackenzie reports. the native red squirrel — not a common sight in the uk, but now limited to areas like here in barhill wood in dumfries and galloway. how many red squirrels would you have in this wood? in november last year, we had over 30 — which is an exceptional amount. you know, there�*s not many places in scotland where you�*d find that level. so what makes this the ideal habitat for the red squirrel? principally it�*s the age of the trees, that they are now producing cones regularly — and that enables food to be available at different times of the year. the larch produces cones in the summertime, the scots pine in the winter. so it gives the squirrels a good, wide feeding pattern. but of course, they�*re in competition with the grey squirrels. wherever you get the grey squirrels, the reds are going to disappear, unfortunately. for some, the red squirrel project is vital. well, they're beautiful creatures and they're native to the uk so i do believe that, since the grey squirrels are introduced and have wiped them out, or almost wiped them out, it's important to make sure that we can keep our heritage. it�*s a really nice effort from the local community. the scottish wildlife trust said having a variety of trees benefits the red squirrel, and a predator, the pine marten, helps to control the grey squirrel population. but that is not enough. grey squirrel control is going to be necessary for a long time yet. so that will be the key thing that needs to keep continuing, in a targeted landscape—scale approach. which is tricky and hard work, but it's what is needed if we want to keep our red squirrels. the battle for survival with the more feisty grey squirrel is likely to continue for some time. alexandra mackenzie, bbc news, kirkcudbright. now it�*s time for a look at the weather with matt taylor. not as cold or quite as foggy for many of you tonight, compared with recent nights. a lot more cloud around to begin with. a few showers spreading down across south wales, southern parts of england, but it is in scotland and northern ireland the breeze picks up, touching gale force at times in the far north, outbreaks of rain for many as we go through the night, turning to clearer skies later. temperatures by and large above freezing, maybe one or two pockets of frost around first thing sunday but nowhere near as abundant as it has been of late. a damp morning for parts of northern england, north wales, as a weather front pushes south, weakening as it works across the rest of england and wales, nothing more than a cloud and one or two isolated showers later on. it does then introduce lots more sunshine across the country for the afternoon, certainly a brighter day compared to today. breezy across the north of scotland but the wind is coming off the atlantic so by and large temperatures will be a little bit up on what we�*ve seen over the past few days, 7—11 degrees. then through the week ahead, after a sunny start to the week we are going to see some rain and wind at times in scotland and northern ireland on tuesday and wednesday
