a report for the un says switching to a diet without meat could help slow down global warming. inter is not for everyone. that is why i am here. football's transfer window has just closed. manchester united sell romelu lukaku to inter milan for £74 million. it's exactly 50 years since the beatles walked across that zebra crossing in abbey road for their seminal album cover. we'll be talking to hunter davies, author of the band's only authorised biography. detectives have described a machete attack on a policeman in east london as "frenzied, unprovoked and shocking". the patrol officer was stabbed several times after stopping a van in the leyton area. scotland yard says he was "seriously injured" but will recover. a man in his 50s has been arrested. andy moore is at the scene in east london for us. the latest on the police officer is that he is in a stable condition. he had an operation on his hand this morning. he has been widely praised for his bravery and presence of mind in being able to tease the suspect despite being seriously injured. an eyewitness told us he saw the police officer on the ground in the road behind me, his uniform had been taken off, he was being given cpr by collea g u es taken off, he was being given cpr by colleagues and paramedics, lying motionless at that stage, and eye said they thought he had been killed. it should have been a routine stop, but it turned into what police described as a "frenzied, two minute long attack". after a brief police pursuit, a large white van was pulled over. the driver, in his 50s, became aggressive and pulled out a machete. we could see the van and the officer was there. he just got attacked and obviously me and the mrs were standing here, talking about it. we felt really sorry, not only because it was a person lying on the floor, but on top of it because it was a police officer, like the person who is actually responsible for our safety and stuff on the streets. as the police investigation began, the officer was being treated in hospitalfor his injuries. a wound to his head required stitches. he was due to undergo an operation for the injuries to his hands, sustained in trying to fend off his attacker. police say the incident was filmed on a body worn cameras but they are still seeking witnesses. the members of the public who were there — i would urge you to come forward. while we've got a man in custody, we need to get to the bottom of why this happened and the fuller picture of what happened just before and then during the attack. the prime minister has paid tribute to the bravery of the police officer. what this underscores, for me, is the bravery of our police people, who actually go towards danger to keep us safe. 0ur sympathies are obviously with the officer and his family. i think you've got to give officers the confidence that they need, that when they ask somebody coming towards them, who may be carrying a knife, which is a danger to them and to everybody around them, that they have to have the power and the confidence to do that emotionally challenging thing and do stop and search. a man has been arrested on suspicion of grievous bodily harm. police say it's not being treated as a terrorist attack. that suspect who was arrested is still being questioned. he is 56 yea rs still being questioned. he is 56 years old. the second officer in the patrol car, who made the arrest, she was a female police officer. priti patel has paid tribute to the bravery of the officer injured. she said she was horrified by the shocking stabbing of one of our brave police officers in leyton. his courage in the face of danger shows how police put their lives on the line to protect us everyday and i wish the officer a full recovery. the attack came as figures show there's been a dramatic rise in the number of women and girls caught carrying knives in england. data obtained by bbc news show a 73% increase in offences over the past five years, with nearly 6000 cases recorded. youth workers say some women end up carrying weapons for gangs, because they're less likely to be stopped by the police. sarah corker has our special report. manchester city centre in the middle of the afternoon and a teenager has been threatening someone with a knife. but look closely and there's a difference here. this is an 18—year—old woman. she was carrying this, a 12—inch bread knife. across england, female knife posession is rising. the first thing i would go do is run for a knife. i would go for a knife — threaten, cut. it was like this mist came over me and i charged at her with a knife, stabbed her straight in the top of her head. louise ann and teresa both lived in a world fuelled by violence and were addicted to drugs. for 12 years, teresa carried a knife. she went to prison for attacking her neighbour. i stayed in this lifestyle ofjust brokenness, in very abusive relationships to the point that my kids were taken into the care system and at that point i completely lost all hope so i started taking heroin. i was out on the streets, working in prostitution, and i used to get in a lot of fights, there was a lot of violence. i'd either have a knife or a pair of scissors, something sharp. women are often overlooked or ignored when it comes to tackling britain's problem with knife crime. it's framed as a male problem. but figures obtained by the bbc show that, on average, one woman is caught carrying a knife here in the north of england every single day. in england, there's been a 73% increase in knife possession cases involving women in the last five years. since 2014, there's been more than 5,800 cases of women caught carrying knives. around a quarter of those involved girls under the age of 18. unfortunately you have exploitation from the school gates. and the causes are complex. youth workers in leeds say some women willingly carry knives to rob people. others are being manipulated by men. they are asked to maybe be the courier of these weapons. they will agree to do that because they want to please their partner. so what we have come across are women who will hide the weapons, say a knife, ina pram. you know, which police officer is going to look at a female who is walking with her baby in a pram and stop and search her? in the west midlands, these weapons were found hidden in a designer handbag. louise ann now lives in salford. she first used a knife as a teenager in london to get cash. then, in her 20s, it was a way to protect herself in abusive relationships. i remember i used to have knives in my backpack. i used it to threaten people. give me what you've got, take it off of them. i used to sleep with a knife under my bed, because i started to get quite paranoid, the more stuff that i done. i remember my boyfriend bought me this... he actually bought me knives. knives got used all the time. across the pennines in sheffield, south yorkshire police is one of seven forces with extra powers to tackle violent crime. specialist officers target known trouble spots and have a more visible community presence. i don't think it is any more nuanced for women than it is for men. it is about vulnerable young people getting drawn into the fringes of organised crime. back in manchester, the 18—year—old woman seen swinging a knife was sentenced to 12 months in prison. while louise—anne and theresa are both addiction free and coming to terms with their past. put yourself around those positive things. if you hang about on the streets, you're going to reap destruction. women carrying knives has often been described as a hidden problem but, with the numbers increasing, the pressure is on police to tackle it. sarah corker, bbc news. eden lunghy is with me. she's part of a group of young researchers from the take back the power project on knife crime and youth violence who delivered a letter to number ten today calling on borisjohnson to put solving knife crime at the top of his priorities. tell is a bit more about what you wa nt tell is a bit more about what you want the prime minister, the government and authorities to do about knife crime. the letter was from young people who have been working on street violence under knife crime projects in london and we are calling on borisjohnson to invite the young people who have lived experience of violence, a lot of time when the discussions are held, young people do not lead the discussion. we think this is an important way that boris johnson cannot just say he important way that boris johnson cannotjust say he is going to put 20,000 police because we don't think thatis 20,000 police because we don't think that is the only solution to solve the issue. police can sometimes actually make matters worse. especially with young people affected by serious street violence, affected by serious street violence, a lot are from marginalised groups. they don't feel like the police don't protect them and are over policing and it can cause a disconnect. we need to look at solutions that come from young people who have lived the lifestyle because their solutions will be a lot more radical and implement real change. and our report highlighting how many women and girls carry knives. are you surprised? no mac. a lot of the time the discussion is focused on men and you have to remember that these men do not live in isolation, they live in and amongst women and these women can also be living that lifestyle. if young men feel like they need to protect themselves, it is not surprising that young women feel like that as well. a lot of the time the media covers women as victims but maybe they are carrying the weapons as well. when you talk about people needing to protect themselves, is that one of the principal reason is that so many young people, men and women, are carrying knives? there are a range of reasons, from just wanting to protect themselves, yes, that is one, but also not feeling safe. when you feel like the police aren't there to protect you, you kind of have to want to fend for yourself. when you talk about the police, surely extra police officers will help counter the levels of serious crime and violent crime in the country which have been really concerning. i don't thinkjust adding more police is the one solution to this. there has to be a multifaceted solution, amnesties, putting young people at the forefront of discussions, and dismantling structural violence. a lot of young people are at the receiving end are from marginalised communities. i don't think the police can just solve the issue. how much of the knife crime is from gangs? i think it is hard to measure because who is defining what a gang is? it could literallyjust be a group of friends and it starts and turns into something else. the police called him a gang but they arejust friends. it police called him a gang but they are just friends. it is police called him a gang but they arejust friends. it is hard police called him a gang but they are just friends. it is hard to measure how much of it is coming from gang related matters. do you think knife crime is getting worse year on year? the statistics seem to indicate this, we are seeing more young people dying of knife crime.|j think there has been more awareness, especially in the media, but i sometimes think it is scaremongering and putting out a perspective that there is more happening. this has been an issue for a long time and we can see from our research that this is not just happening can see from our research that this is notjust happening today, but we need to look at the root causes and how structural violence, poverty and inequality has a big impact on young people breaking news now and we are hearing from our colleagues in belfast newsroom that riot police have pulled out from the site of a bonfire in northern ireland because there was a substantial threat to life, according to sinn fein. officers were attacked after going in to support contractors who were brought in to remove the wooden pallets. missiles were thrown at police and an officer was knocked down. there are warnings that the bonfire is a risk to local tower blocks. sinn fein has said authorities are now considering evacuating residents, and that the majority of the community do not want the bonfire. some other news coming in from police in essex. they are saying that three teenagers got into difficulty at sea and have been recovered from the water close to cla cton recovered from the water close to clacton pier. they were taken to critical condition at —— hospital in critical condition at —— hospital in critical condition. a —year—old girl has died, an 18—year—old man is in critical condition and a 15—year—old girl is expected to make a full recovery. the police say immediate family members have been informed and are at hospital. three people who got into difficulty at sea, recovered from the water close to cla cton recovered from the water close to clacton pier, a 14—year—old girl has died in hospital, an 18—year—old man ina died in hospital, an 18—year—old man in a critical condition, and a 15—year—old girl expected to make a full recovery. more on that as it comes in to us. climate scientists are warning that high consumption of meat and dairy produce around the world, is fuelling global warming. researchers say intensive farming releases carbon into the atmosphere, helping to raise temperatures. now the united nations intergovernmental panel on climate change says more people could be fed using less land, if there were less meat consumption, and a switch to plant—based diets. our environment analyst, roger harrabin, reports. this alpine landscape was once covered by forest, the trees sucked carbon dioxide from the atmosphere and regulated the climate. then humans cleared some of the land forfood but cattle burp methane and that strongly heats the atmosphere. this sort of low intensity grazing may produce protein from poor soil and it does have some environmental benefits but it create more greenhouse gases than growing plant protein. scientists meeting here in the alps are not saying we have all got to go vegan to protect the climate, they are saying that we do need to cut down on red meat and dairy produce and shift on towards eating more vegetables. and that message may not go down very well here in a region that is so heavily dependent on cheese and meat. we need to do what we can on the land but actually it's important to maintain food production and so there will always be some emissions on land. so in fact we have to do as much as we can in the energy and industry and other sectors as well. we need to do everything now really if we are to have any chance of avoiding the worst impacts of climate change. debate here has been fraught because of the way we use the land is so complex. among the experts' recommendations are on biofuels, limiting the area used to grow trees to be burnt to make electricity. this could conflict with feeding the world. 0n deforestation, working harder to protect the trees that protect us from climate heating. 0n desertification, finding ways to feed people that don't involve degrading the soil through overgrazing. then there is the way we eat. in the west we over—consume meat, dairy. that is bad for our health, it is bad for the climate, it is bad for water, it is bad for land degradation. so if we were able to reduce our consumption in the west of meat and dairy then we could have significant benefits for the climate but also for our health. scientists also want to stop food being discarded because wasting food means the greenhouse gases created to produce the fertilisers to grow the crops have been for nothing. a charity in geneva redistributes waste food. here they are taking stale bread and turning it into new cookies. this avoids having to produce fresh flour to make the cookies. here is a positive sign, these peat moors in the north of england were previously drained so animals can graze. when peat is exposed to the air it gives off greenhouse gases, so now they are blocking up the channels to soak the peat again. one of the easier options in what for scientists has become an increasingly desperate attempt to stop the planet overheating. roger harrabin, bbc news. and later in the hour we'll be hearing from the president of the national farmers' union for her view on today's recommendations. the headlines on bbc news... the prime minister praises the bravery of a policeman left critically injured in a machete attack in east london. a dramatic rise in the number of women and girls carrying knives in england — police have found blades hidden in designer handbags and babies' prams. eating less meat could help slow down global warming, according to climate scientists. and in the sport, their premier league transfer deadline has passed. romelu lu ka ku league transfer deadline has

general election in the autumn, simply saying that britain will leave the eu on october 31st. we are going to leave the european union on october 31st, which is what the people of this country voted for. it's what mps voted for and it's what i think the parliamentarians in this country should get on and do, thank you. you're not concerned about disregarding the will of parliament? i think that mps should get on and deliver on what they have promised over and over and over again to the people of this country, they will deliver on the mandate of 2016 and leave the eu on october 31st. thank you. 0ur political correspondent tom barton is at westminster. all sorts of speculation about an autumn election, constitutional crises and so on. yes, borisjohnson said mps should get on with it and deliver brexit on 0ctober get on with it and deliver brexit on october 31. the problem for him is that in parliament there are lots of mps in and outside his party who are determined to stop that happening u nless determined to stop that happening unless there is a comprehensive overarching deal in place with the eu. among those is anna subaru, former conservatives and now the leader of the independent group for change. she said mps should be very careful about using the mechanism of a vote of no—confidence in order to stop a no—deal brexit because she said mps wouldn't supportjeremy corbyn and that it might be difficult to find somebody else who can command a majority in parliament and become an alternative prime minister. we wa nt we want those sensible centrists coming together. now, that would require somewhere in the region of around 300 labour and conservative backbenchers to show the sort of courage which sadly so few have shown over the last three years. but nothing is impossible but the danger is that unless that happens, and there is a vote of no confidence, then boris johnson chooses when he calls that general election. and i'm afraid the greatest tragedy would be if we crash out on october the 31st and we hold a general election on november the 1st. so the reason that anna subaru is nervous is because it is down to borisjohnson to decide the date of the general election. this afternoon there are reports that his advisers are saying that in that scenario he would aim to have that election held after the 31st of october essentially meaning that no deal would happen by default before an election had ta ken would happen by default before an election had taken place and so that leaves those mps concerned about no deal having to think about whether there might be an alternative mechanism, perhaps using parliamentary dynamics to try to find a different way of stopping a no—deal brexit. that has drawn criticism from brexit supporters, including the brexit party mep claire fox. the majority of mps in the house of commons are completely at odds with the electorate and in that way the kind of chasm between the electorate and the parliamentary parties of all three parties has revealed that the two—party system is no longer fit for purpose. i think that we have seen a terrible situation where democracy is on the line where we were asked by parliament to take a vote, we voted in good faith to leave the european union and since then they have been doing everything not only to trash our vote but to reduce our reputations by telling us we were stupid or racist or wrong. there is huge amount of speculation and mps on both sides. when mps return from their break at the start of september this place will get very busy indeed. yes, it might. a footbridge connecting two halves of a medieval fortress at the legendary site of king arthur's castle is opening this weekend. hundreds of years ago, a narrow land crossing at tintagel castle in cornwall collapsed into the sea, leaving visitors with a steep climb if they wanted to explore the ruins. the new bridge will reconnect the site, for anyone brave enough to walk the crossing. fiona lamdin has been to see it, and a warning, her report contains flash photography. for centuries, tintagel castle has been split in half, divided by the sea. but, for the first time since the middle ages, the island and the mainland have been reunited with a new footbridge. people can actually walk from the original entrance, through the mainland courtyard, across this bridge over into the island where the great hall lies. it's about creating a sense of wonderfor people, and also for people to be able to understand the actual castle better. because they can actually progress through it as our ancestors did. it has taken nine months to build the 70—metre bridge, using 47 tonnes of steel and 40,000 cornish slate tiles. but it actually isn't a new concept. if you go back to the 15th century, the castle was still one, joined by a narrow neck of land before it eroded and fell into the sea. it is one of the most important places in britain for that period after the romans. there was a myth that this is where arthur was conceived, so it is very closely connected with arthurian legend. that is probably why richard, who was earl of cornwall in the 13th century, decided to build this later castle on this site. we are finding incredible stuff on this site. over 100 buildings, it was bigger than london as far as we know, at the time. for the last 100 years the only way of getting from the island to the mainland was this way, let's go. it's a 57—metre drop down to the sea. well, i've counted them, there's 272 steps and, i can tell you, the last few are pretty steep, phew. i think it looks absolutely an amazing achievement and i think it fits in really well with the landscape. if i brought my elderly mother along, then definitely the bridge. this landscape has been without its crossing for hundreds of years. the earth and rock now replaced by steel, reuniting a divided castle. fiona lamdin, bbc news. still to come on the bbc news at 5... why

to fast—track basis for top scientist coming to britain as he says he is confident of a deal that can be done with the european union. right police pulled out from a site of a bonfire in northern ireland after missiles were thrown at them and an officer knocked down. do to be lit tonight to mark down the introduction of internment in 1971. the promised or have taken to facebook to announce what appears to bea facebook to announce what appears to be a new policy on immigration. more shots of said government is going to change the rules on immigration to make the uk more open, more welcoming to scientist from around the world. our political correspondent who we heard from earlier is still at westminster so what exactly half the promised or been saying about immigration? what exactly half the promised or been saying about immigration7m the last hour, borisjohnson has been taking part in a facebook life strea m been taking part in a facebook life stream on line, talking about brexit and about his policies. and this is and about his policies. and this is a new policy which has been announced today. he was on a visit to 0xfordshire a little earlier to talk about this as well. promising to introduce fast—track visas, a new route to getting visas for scientists and researchers, saying that he wants to attract elite researchers from around the world here to the uk, from europe and the rest of the world. and so he is asking ministers to work with the scientific community to find the best way of doing this. one of the options they are going to look at our potentially abolishing the cap on numbers for what is known as tier one, the exceptional talent group of potential immigrants, taking the cap away from them altogether. also potentially removing the need for people with certain skills to have employment before they can get working visa to come to the uk or alternatively expanding the group of institutions that are allowed to sponsor institutions that are allowed to sponsor people for visas to include a larger number of scientific and research employees. of course, science, the high—tech industries are usually valuable to the uk. go to places like 0xford where boris johnson was today or cambridge, you get a sense of that. they have also been among the most outspoken critics of brexit and i think today's announcement will be seen as an attempt to calm their nerves as it brexit and the 31st of october gets a little bit closer. tom, thank you very much indeed. let's get all the sport with gavin, the transfer window slamming shut about half an hour ago. what are the big deals? good evening. yes, premier league window closing for several closer for the season begins tomorrow. let's bring in our sports correspondent david 0rnstein with the very latest. romelu lu ka ku romelu lukaku going from united to enter milan. with a have trouble replacing him? they will not replace him in this window for sure. maybe alexis sanchez will come into the picture but they have £74 million in the bank for when they choose to spend it, perhaps nextjanuary or the following summer. you get see the following summer. you get see the welcome he received in milan, quite extraordinary that. this a player who almost scored a goal every other game for united but never really captured the heart of the fans and he departs to link up with antonio conte, who is one of him fora with antonio conte, who is one of him for a long time. could be some of the money they paid for harry maguire with that £74 million. totte n ha m maguire with that £74 million. tottenham quite active today. bringing in ryan sessegnon but not quite hitting the target with a move they wanted from italy. the big one they wanted from italy. the big one they were after, the juventus playmaker, forward, call him what you like, he was a player they wa nted you like, he was a player they wanted and working on for a long time, 25 years old argentine international and a real talent of the game. he was close, very close but in the end who vented decided they wanted to keep him at the club because they initially wanted romelu lukaku, because they initially wanted romelu lu ka ku, who went because they initially wanted romelu lukaku, who went to enter milan as we said. also issues around agent's fees, salaries and image rights. it isa fees, salaries and image rights. it is a loan with obligation to buy at the end and ryan sessegnon from fullman a permanent deal with a five—year contract is very exciting. arsenal bringing in david luiz. david luiz has not been announced yet but it will be. a remarkable deer —— with a two—year contract coming in from chelsea to solve their centre at half problem. and kieran tierney coming in from celtic ona kieran tierney coming in from celtic on a five—year contract and that i would both of those players adding to what they have already done in this window. also news with andy carroll going back to newcastle. iwobe came through yesterday around the same time as david luiz, a bid from everton rejected. went quiet overnight but has come up again and everton have agreed a deal with arsenal around 35 or £40 million to com plete arsenal around 35 or £40 million to complete the medical. andy carroll back to newcastle after he left in 2011, a one—year deal and quite extraordinary a story. thank you, david. busy day in the transfer market of course. wolverhampton wanders have kicked off in their first european game outside the uk since 1980. they're in armenia, a round—trip of over 6000 miles, playing pyunik in their europa league third round qualifier. they are currently 1—0 wolves. matt doherty with the goal there. the new saints, rangers and aberdeen also play their first legs away from home later this evening. one of the greats of south african and world cricket, hashim amla, has retired from the interantional game. he played 349 times for his country in all three formats, scoring more than 18,000 runs. the 36—year—old holds south africa's highest test score, his unbeaten 311 against england at the oval in 2012. he'll continue to play domestic cricket. we'll have more for you in sportsday at 6:30pm. un scientists have warned that drastic changes are needed in global land use, agriculture and human diets to limit global warming. the intergovernmental panel on climate change says unsustainable farming and deforestation is having an increasingly negative effect on the environment, and one solution is for people in rich countries to eat less intensively—farmed meat. 0ur science editor, david shukman, has been to one leading european plant research centre to get reaction. cutting back on meat is a good idea for adults who are healthy. it's not necessarily a good idea to completely cut it out. there are groups that really need some meats. that includes women, children, the elderly, but most people in western countries just eat too much meat. 0n the other hand, you have large groups of the population in africa and asia who do not eat enough meat, so we will need to find a new balance. but animals are essential in the overall agricultural system in the world because they can eat some of the food waste and they can also convert grass into something we can eat. a lot of people, including young people, are very worried about climate change and where the world is heading. what's your sense about whether there are solutions? i understand the worry, but i'm also convinced that there are many solutions and that we can adjust to the pace of change. we've learned to deal with droughts, we've learned to deal with floods in the past and we'll be able to do that. we'll also develop new crops with new genetic characteristics, new crops that actually can harness the sunlight even better, so all that will help us in the right direction in the next few decades. let's talk more about this report. i'm joined now by minette batters, president of the national farmers union — she farms beef, sheep and arable crops on herfarm in wiltshire — and dustin benton is policy director at the green alliance think tank. thank you for being with us. how would you summarise what this report for the un is calling for in terms of us as consumers and producers? what to be need to do to change? the report is really a warning shot, say climate change is already affecting the way in which we use land and already harming nature and creating risks for food security. although it does not make recommendations for people, it does say we are going to need to change the way in which we farm and grow a lot of forests and protect our peatlands and that is very important for the uk and will change the way we eat. but if the top line of it. from a former's point of view, what do you make of that suggestion we should change our dietand that suggestion we should change our diet and the way that we farm and produce food? can ijust say i am surprised at how this is been reported today because i have read the report and nowhere does it say that animal products are not part of a healthy, balanced diet. ithink this is a global report and here we are in northern europe and actually it is where we should be producing livestock as part of a healthy, balanced diet and we are not consuming here we should be able to explore as what you heard in geneva. so it is very much saying it is about a healthy, balanced diet and about a healthy, balanced diet and about sustainable systems and that is of course what we at the nf you are up forthem is of course what we at the nf you are up for them have sent we can actually deliver net zero without downsizing production here by co—opting in climate from the cut farming methods. so we see farmers as part of the solution. how climate friendly is british farming?” as part of the solution. how climate friendly is british farming? i think it is incredibly climate friendly already. we can certainly grow more trees and enhance our hedges but we can really focus on effective productivity and efficiency to make sure that we are really farming efficiently and farmers are up for that. they see the opportunity and most importantly we have the right climate here. we grow grass and that needs to be raised and that is a point made their force that we can actually turn grass into high—quality food. but if we are not eating it here, we can export it across the world. i hear what you are saying but is the report not suggesting that actually it would be helpful if consumers did eat less meat and more vegetables generally? that that will be better for climate change going forward? the report put out a series of options and there are 28 big ones. the one is eat less meat. we think that will be part of it and for british farmers, should be about less meat and better quality meat. we think the perspective of a livestock farmer for civil, the uk exports about a third of its me and some of those imports are much higher carbon and much worse than we produce here for nature. so if you produce are making that we replace it with good quality and high standard uk food. that is one part of it. but a lot of the rest of it is about ending the extraction of pete, peatlands are a major carbon store in the uk and we don't treat them well. a lot of it is going forest but new big for to help suppress carbon and give people a place to enjoy and recreate in. and partners to help farmers sequester carbon in the soil they are response before by increasing the way in which they manage their pastor into helping to decarbonise cows and notjust get rid of cows. he says we should produce less meat but better quality meat. would you agree with that? i think we are producing great quality meat here and we should be really proud of that. i think it is extraordinaire that. i think it is extraordinaire that food waste in the number one thing that the ipcc talks about has not even been mentioned today. we wasted £16 billion worth of food and that has not even been mentioned. i just continually amazed at the focus on meat eating and meat production when in the uk, it is absolutely essential that we manage our carbon. the point is made very well about how important it is to have sustainable systems and actually enhance the carbon sinks that we have now. livestock is a vital part in all that and i think this adds massive confusion to what a healthy diet is all about. the nhs and public health england and all advice in the british nutrition foundation say eating meat is a vital part of the die and i don't think that has been made clear today. and what would you said that? me can be part of the die but we need to eat less. we need to eat less that is good and more good—quality in that can be donein more good—quality in that can be done in ways that are good for farmers. farmers need to get more of the value and produce the kind of high—quality beat the your farm produces. not a question of a loss forfarmers but i think produces. not a question of a loss for farmers but i think your point about food is well—made. we know the infilling, they waste half the amount of food the uk does and everybody is wealthy and every thing is working and that is to do with the power of supply chains in the way in which supermarkets and food manufacturing companies create incentives for farmers to accidentally in that wasting food in the supply chain. those things need to change and we need a new agriculture bill which supports farmers to give and do the can of things in very nature friendly and low carbon things they want to do. i have to pay tribute to the nfu for saying they want to get to a net zero farming and land use by 2044 a bit of a pioneering commitment. we have looked at that we think it can be achieved. we have to leave it there but thank you so much both of you. thank you for coming on. a teenager is to face trial next year, accused of throwing a six—year—old boy from a

the territory to terror and separatism, resulting in the loss of thousands of lives. in retaliation, pakistan has suspended all bilateral trade with india. kashmir, which is majority muslim, is claimed by both countries, and has proved a flashpoint for the nuclear armed neighbours over several decades. naomi grimley has the latest. communications have been cut in india administered kashmir. but these images show how tensions have risen in the days since new delhi revoked this region's special constitutional status. the security services patrol the area, enforcing curfews in the eerie quiet. but stones and masonry scattered across this street are a tell—tale sign that angry protesters are making their voices heard when they can. this was already one of the world's most militarised

translation: a new era has now begun. rights and responsibilities of all the citizens are the same. i heartily congratulate all the citizens of the area and the rest of india. but many kashmiris feel it's part of a hindu nationalist plan to change the demographics of the country's only muslim—majority state. all this when kashmir has already witnessed decades of violence and insurgency, trapped between the rival territorial claims of two nuclear powers. naomi grimley, bbc news. fans of the beatles have been gathering in london to mark 50 years since one of the most iconic photographs of the band was taken. the picture showsjohn lennon leading the group over a zebra crossing outside the abbey road studios in north london where most of their songs were recorded. the image is now one of the most famous in the history of pop. lizo mzimba reports from abbey road. for half a century, fans from all over the world — fans of all ages — have come here to recreate and, in their own way, feel a connection to perhaps the most famous band ever. i'm coming from belgium, and i'm here for thursday at abbey road. abbey road is special because it's the last beatles recording. we are coming from mexico, and this is special because we really are fans of the beatles and we're excited to be here in london. we like the music. i come from uruguay, and the beatles are special and i like the music. # all you need is love... # over the years, abbey road studios became almost synonymous with the band, who recorded so much of their music there. # all you need is love... # they were the most famous band in the world, but even they may have underestimated the impact those short few minutes would have, as they emerged from the studios there, came out onto the road and, at exactly 11:35am, walked backwards and forwards over the crossing while photographer iain macmillan took six quick shots. the fifth was chosen and entered music history. # come together... # the abbey road album is particularly special to fans as it represents the last studio recording sessions to involve all four beatles together. half a century on, things were a little busier than that day in 1969, the police eventually having to intervene to control the fans blocking the road. and almost 50 years to the minute since the famous shot was taken, four members of a tribute band recreated what has become an image that encapsulates what the beatles meant to so many. lizo mzimba, bbc news, abbey road. hunter davies wrote the only authorised biography of the beatles and spent 18 months with them when they were at the peak of their musical career. very good to talk to you. thanks for being with us. tell us a bit more about the picture, that famous picture, that iconic picture. right, you are an educated culture person. looking at that cover, first of all, what strikes you as being unusual as an album cover? you have got two seconds. sorry, too late. there is no title, abbey road does not come on the cover. the beatles name is not therefore that there are no words on the cover and that was incredible for 1969 for some it what it proved an illustrated was the the beatles were the most famous group of people in the universe and they did not need to do it. you have them going across and john was actually fed up with the beatles and he was leaving but he was always a leader so he goes across first. one, two, three are in suits. they were made bya three are in suits. they were made by a friend of mine called tommy nutter. george is in denim. look carefully a nd nutter. george is in denim. look carefully and you will see that george, ringo and john are in step, left foot first, but paul, look carefully, you see paul in his right foot is first and secondly he is barefoot. he was out of step and that proved to all the fans that he was dead, all the fans thought. that vw in the back there, that vw is now ina museum vw in the back there, that vw is now in a museum in germany. that is the most famous vw, cannot believe it. this man here standing idly watching, he has done his memoirs internet to be american. this was symbolic because the beatles were powerful and england, mega symbolic because the beatles were powerfuland england, mega in germany and had a huge success in hamburg and secondly huge in america. if they plan the whole think they would have a japanese person there as well. these people walking across, the photographer took six shots was about have a copy of the five which were not used. and these five, a friend of mine who was now past, i got in the sundays but i cannot show them to you because it is not his copyright. i paid a lot of money for them and i have them somewhere on these walls somewhere. they did this in the morning break at 11:30am and they are working here on abbey road, the album, and just came out and did in 50 minutes. on abbey road, the album, and just came outand did in 50 minutes. it was paul's i did. paul did a drawing of how it should be and if you thing about this, a 50 minute —— 15 minute, not a studio, cover shop for an album, sergeant pepper took about three months today. i was in the studio and it took about three months and they had 57 or 58 different images of famous people, cut out. in the studio was adolf hitler and jesus was up at the last minute, they were persuaded not to include those. with the cover took three months to organise because they had to contact every famous person's descendent or manager or agent to get permission. here, all they did was permission for four people. so this is the quickest, cheapest cover that was ever done. fantastic. what a wonderful explanation and analysis of the photo and the cover, go to talk to you, hunter, thank you very much for being without us.
