a major shift in labour's brexit policy — jeremy corbyn says there should be another referendum on a conservative brexit deal — or a no—deal exit. the labour leader said his party would then campaign to remain in the european union. but it's still not clear what labour would do if it won a general election — we'll have more from westminster. also this lunchtime... downing street gives its full backing to britain's man in washington — as a former ambassador says president trump is wrong to say it won't work with sir kim darroch but president trump has just launched a new attack. calling the ambassador a very stupid guide.

a technique called gene—silencing which doctors say will be life changing is given the go—ahead for use on the nhs in england. this is huge. this is making a disease that was previously untreatable, treatable. the first study of its kind has found most ethnic groups in the uk earn less on average than white british workers we are live at wimbledon, the women ta ke ce ntre we are live at wimbledon, the women take centre stage on quarterfinal stage. coming up in the sport on bbc news we'll have the latest from old trafford. the first of the world cup semifinals, new zealand making a shaky start against india. good afternoon and welcome to the bbc news at one. the labour leaderjeremy corbyn, has committed his party to campaign for remain in another referendum

on a conservative brexit deal or a no—deal exit from the european union challenging the next prime minister "to put their deal to the people". the major shift in the party's policy came after a meeting of the shadow cabinet this morning. but it's still not clear what labour would do if the party won a general election before brexit was resolved. our political correspondent nick eardley reports brexit is not always been easy for jeremy corbyn, the landscape for the labour party has been far from simple. party members back staying in the eu but when it comes to labour voters, the picture is more complicated. for months in here the party has tried to keep everyone happy, but road is running out. in a letter to all labour party members, mr corbyn writes

sometimes watching the labour party brexit position evolve has been a bit like watching an oil tanker turnaround, ina bit like watching an oil tanker turnaround, in a meeting up there at the shadow cabinet there has been a shift agreed. now the party will say to whoever the new prime minister is, you have to put your plan to the people and if they do, the labour party will back remain. all clear? not quite. we still don't know what labour would campaign for any general election and whether it would back remaining if it managed to get its own brexit deal. it's entirely possible for the government, a labour government to put forward that this is our deal but to give a free vote to the front bench, a free vote to labour mps to campaign on what they want, it's happened in the last referendum in the 70s, 75, happened in the last referendum in the 705, 75, it happened in the last referendum in the 70s, 75, it can happen again. some anti—brexit campaigners want jeremy corbyn to go further, some

brexiteers will cure the labour party of ignoring the referendum result but the party is moving in a direction of backing staying in the eu even if thejourney direction of backing staying in the eu even if the journey isn't yet complete. our assistant political norman smith is at westminster. the key question in regard to the labour party, does this give us absolute clarity, norman? you wish. i think the truth is it gives us some significant clarity but there is still a big dollop of confusion around so ahead of a general election, we have clear blue skies, we can see what the labour party a up we can see what the labour party a up to. if there is a general election we are in a bit of a pea soup, jeremy corbyn says ifjeremy hunt or boris johnson soup, jeremy corbyn says ifjeremy hunt or borisjohnson were to press ahead with no deal or a tory deal, then the labour party would oppose it and press for another referendum and would campaign for a to remain. that is clear but what is not clear

is if instead, there is a general election, then we simply don't know what would happen. why? jeremy corbyn has not told us. we get a clue from the big unions who yesterday suggested, in that eventuality, the labour party would campaignfor eventuality, the labour party would campaign for brexit but a labour brexit deal. but that would leave you with the bizarre situation of if borisjohnson orjeremy you with the bizarre situation of if boris johnson orjeremy hunt you with the bizarre situation of if borisjohnson orjeremy hunt became prime minister, then the labour party would be against brexit but if jeremy corbyn was poised to become prime minister and the labour party would back brexit which is why no one, i think, would back brexit which is why no one, ithink, believes would back brexit which is why no one, i think, believes that position can stick. and many remain backing labour folk believe the direction of travel now is all one way and slowly, but surely, they are reeling in mr corbyn to make labour and openly remain backing party. and he may not have been landed yet but it's hard to see mr corbyn getting off the hook of remain. norman, thank you.

downing street has reaffirmed its full support for the uk's ambassador to the us, after president trump said he will no longer work with him. and the president has treated in the last few minutes, calling the ambassador a pompous fool and a very stupid guy. it follow a leak of emails written by sir kim darroch, describing the trump administration as inept and dysfunctional. in a series of tweets, mr trump also said that theresa may had made a mess of brexit, adding he was thankful that the british people would soon have a new prime minister. our diplomatic correspondent james robbins reports. thank you for your continued hospitality. the emir of qatar thanks to donald trump at a white house dinner last night, you would think the british ambassador sir kim darroch was not there. originally invited, then warned off attending by the administration. after his highly critical description of the administration as dysfunctional,

fashion ribbon, clumsy and inept. one of several secret assessments made for whitehall across two years and now spectacularly leaked. the great leak of the cache of documents has stung him to the quick and i think he is also deeply irritated by theresa may ‘s full faith and support in sir kim darroch. put those two things together and from his point of view, you've got a toxic combination which has led to this shower of tweets. and the president tweeting is in century even by his own standards. condemning theresa may for what he calls the brexit mess she and her representatives have created. i told her how it should be done but she decided to go another way. before the president turns on sir kim darroch, i don't know the ambassador but he is not liked and we will not deal with him. sir kim darroch seems safe in his post as ambassador, theresa may has repeated her support for him. and in whitehall, across government leak inquiry is under way. could the messages have been

hacked? that would be a devastating indictment of security or was this a political plot inside the system? whoever has done it has taken a very great care whoever has done it has taken a very great ca re across whoever has done it has taken a very great care across a couple of years to do it, to fill thejuiciest great care across a couple of years to do it, to fill the juiciest bits from these diplomatic telegrams, package them up and hand them to a journalist. i suspect it's going to be quite hard to find out who that person is. but now there's a new tweet from the president. this time done and troll calls sir kim darroch a wacky ambassador and a very stupid president and repeats his criticism of theresa may ‘s entire brexit negotiation. there is no question uk relations with the trouble white house are now intensely strain. the president himself is rejoicing in the fact theresa may will soon be gone. her successor will have to decide how to repair the damage. james robbins, bbc news. let's speak to our correspondent in washington, nick bryant. another flurry of tweets really just in the last few minutes. a tweet

storm for the ages! assuredly words from donald trump, the wacky ambassador that the uk foisted upon the united states is not someone we are thrilled with, a very stupid quy- are thrilled with, a very stupid guy. he should speak to his country and prime minister about their failed brexit negotiation and not be upset with my criticism of how badly it was handled. i told theresa may how to do the deal but she went over foolishly, was unable to get it done. a disaster. i don't know the ambassador but have been told he is ambassador but have been told he is a pompous fool. now, sir kim darroch was supposed to be accompanying the international trade secretary liam fox to a meeting later on with the president ‘s daughter, ivanka trump. ican president ‘s daughter, ivanka trump. i can tell you he won't be attending that meeting. it's his decision. he has decided not to go because he thought it would put ivanka trump in an awkward position. evidently he wa nts to an awkward position. evidently he wants to beat the grown—up not in the room. this decision was taken ahead of this latest tweet storm and

sir kim darroch is the sort of person you would ideally want in that meeting, he knows the lay of the land, he knows the people and the land, he knows the people and theissues the land, he knows the people and the issues at stake, has a lot of expertise. he won't be at that important meeting and so we have this extraordinary situation in washington. the man whosejob it is to preserve and protect the special relationship can't even go to the white house for meetings. an extraordinary turn of events for sir kim darroch, facing this twitter onslaught again from the president. nick, thank you. anti—government protesters in hong kong have said they are not reassured by the territory's leader, carrie lam, describing a controversial extradition bill as "dead." the proposed law — which would have allowed criminal suspects to be put on trial on the chinese mainland — sparked huge protests, even after the bill was suspended. rupert wingfield hayes has more. it has been a month of stunning,

unprecedented scenes on the streets of hong kong. again and again, hundreds of thousands of ordinary people have come out demanding the government withdraw a widely reviled extradition bill. mostly peaceful, there has also been violence, with radical student groups storming into hong kong's parliament. after another huge demonstration last weekend, today hong kong's chief executive finally came out to face the music and make what initially looked like a stunning climb—down. but there are still lingering doubts about the government's sincerity or worries whether the government will restart the process in the legislative council. so i reiterate here — there is no such plan. the bill is dead. "the bill is dead." it certainly sounds like an unambiguous climb—down by hong kong's chief executive, but the devil is in the detail. carrie lam is saying she has

suspended this bill indefinitely, she won't bring it back, and therefore it will die at the end of the current legislative session. but what she is not saying is that she will withdraw the bill now, and that is what the opposition protesters are demanding. opposition politicians of every shade have immediately jumped in to make clear carrie lam's statement is not enough. i don't know why it is so difficult for her to utter word "withdrawal". is it face? or... i don't know what it is. and she knows very well that that is what the people, the protesters are demanding. so she should come out and say, "yes, the bill is withdrawn." carrie lam must be hoping her statement will reassure the protesters — the majority of whom are moderate — that the hated extradition bill really is dead, and they have no reason to continue taking to the streets. the first test of whether it has worked will come this weekend

when more big protests are planned. a new form of medicine called "gene—silencing" has been approved for use by the nhs in england. it will be used to reverse a disease called amyloidosis, which causes nerve and organ damage, and can be fatal. doctors have described the impact of the gene—silencing technique as amazing. our health correspondent james gallagher reports. neil and vince nicholas know the pain of amyloidosis. they had toxic proteins building up inside their bodies that were damaging their nerves and weakening their hearts. the disease runs through families and eventually it's deadly. it decimated our family. but they've been given gene silencing medicine that can halt and even reverse the disease. and you just hope that someone is going to invent a drug. you know, i'm lucky that i'm here today to be able to talk to you about that.

this is how it works. inside our cells are genes, they send out messages containing instructions for running our body. but in this form of amyloidosis, a rogue gene leads to a build—up of toxic proteins. gene silencing intercepts a messenger, disabling it and restoring the correct balance of proteins. today's decision applies in england. choices on which drugs to fund are devolved in the uk. scotland made it available injune. this is huge. this is making a disease that was previously untreatable, treatable. and has the potential to make patients' lives dramatically better. the drug may have saved neil's music career as he was starting to lose feeling in his fingers and his voice. but the implications of this study go much further than the brothers and amyloidosis.

experts say gene silencing is an exciting new area of medicine with the potential to work on diseases that are currently untreatable. james gallagher, bbc news. the time is... it's a quarter past one. our top story this lunchtime. the labour leaderjeremy corbyn has vowed to campaign against a nodal exit from the eu or to remain. and still to come... coming up in the sport in the next 15 minutes on bbc news, we'll have the latest from wimbledon. the british number onejohanna konta is due on centre court soon for her quarterfinal. there is an ethnicity pay gap in britain for many workers, according to the first study

of its kind. the office for national statistics found that members of some ethnic groups earn less on average than their white counterparts — workers from pakistani and bangladeshi ethnic groups had the lowest median hourly pay. but people of chinese and indian groups buck the trend. simon jones has been looking at the data. does the colour of your skin affect what you earn? after the recent row over the gender pay gap, focus has now turned to the disadvantage that others face, with too many ethnic minority employees hitting a brick wall in their careers, according to the government. this is the first analysis we've been able to do looking at specific different ethnicities and their pay gaps in regards to white british. the ethnic pay gap is largest in london, and it's smallest, in fact, it's positive in the north—east and eastern regions of great britain. the office of national statistics calculated that the median pay for a worker who is white british

is just over £12 an hour, but employees from bangladesh earn just £9.60 an hour on average. chinese workers, though, buck the trend, earning £15.75 in comparison. in fact, all ethnic groups other than indian, chinese and those of mixed or multiple ethnicity had lower average wages than white british employees. it's a complicated picture, but unlike the data for the gender pay gap which is reported by companies themselves, today's figures compiled by the office for national statistics come from looking at the annual population survey where people are asked for ethnicity and how much they earn. the pay gap is particularly prevalent in london. when you compare with your colleagues who are not from the same community, the same group, you can see a big gap. yeah, obviously, we are fighting it and i hope by bringing that up, it will make a change. i work in hr, so yes, you can see that beyond a certain level,

there is a discrepancy amongst ethnicities, but i don't think that's anything to do... anything malicious or anything untoward. i think it is that people on that leveljust happen to be white. today's figures don't analyse in detail the reason for the pay gap, but pressure will now grow on firms to address the imbalance. shining a light on the issue gets people and employers and employees themselves talking about where these gaps come from and what they can do, so shining a light on the issue is a really important first step. it won't solve it, but it's a good first step. and to make businesses fully reflective of the communities they serve, the government is now considering obliging companies to publish their own ethnicity pay gaps. simon jones, bbc news. nearly 30,000 cases of cancer in men in the uk are likely to be prevented in the next four decades, say researchers — because of a scheme to vaccinate boys against the human papilloma virus. until now, only girls have

been offered the jab, but from the next school year it will also be available to 12 and 13—year—old boys. lauren moss has more details. whenjamie when jamie rae was whenjamie rae was 44, he noticed a lump on the side of his neck about the size of a iop coin. tests at a clinic in scotland revealed that he had throat cancer caused by the human papilloma virus, or hpv. jamie needed surgery, radio and chemotherapy. i could eat properly. i couldn't speak for a good three months. and i really couldn't swallow anything. i was struggling to swallow water, just because of the inflammation in the burning and pain that the radiation had caused. more or less all of the side right around my throat was terribly burned. it was very painful. girls have been vaccinated against hpv since 2008. that wasn't available to jamie when he was younger, but from

the next school term, boys aged 12 and 13 across the uk will be given the jab for free. hpv is and 13 across the uk will be given the jab forfree. hpv is most commonly spread by sexual contact, and causes most cases of cervical cancer. but it is also linked to several cancers among men. a study by the university of warwick estimates that over the next a0 yea rs, estimates that over the next a0 years, expanding the vaccination programme to boys could prevent more than 100,000 cancers in the uk, including 21,000 fewer throat cancers among men, cases of anal cancers among men, cases of anal cancer can be reduced by almost 7000. and it could also result in 6a,000 fewer cases of cervical cancer. those boys will be protected against some of the cancers that are due to this infection. but they will also protect their partners by not spreading the infection, and that will impact on women and men. so we should see a major change in the rates of cancer in the future. older teenage boys will have to pay for the vaccine, but doctors say they will be protected because women up to the age of 25 can receive it. gay

men under a5 years old are eligible to get it for free. a recent study found that over the last ten years, there has been a dramatic reduction in cases of hpv and precancerous growths. it is hoped that this roll—out will save more lives in the decades to come. lauren moss, bbc news. cressida cowell, the author best known for her series how to train your dragon, has been announced as the new children's laureate. let's speak to our arts editor will gompertz. remind us what the children's laureate is about and the importance of the role. is a really important advocacy role. it started 20 years ago. cressida is the 11thjune is low it. quentin blake was the first. child has just left. it low it. quentin blake was the first. child hasjust left. it is low it. quentin blake was the first. child has just left. it is a two—year term, and you come in with an idea of how you want to change things or shake things up. what do you want to put on the agenda? she has come in with a giant to—do list, she says. one of the things she wa nts to she says. one of the things she wants to see is all primary schools

having a library and a librarian and a good choice of books, classic and new. then the right child can have a right book at the right time. it is a worthy thing, but quite expensive. the other thing she wants to do which is not expensive at all is to encourage creativity in children, the joy of writing. i spoke to her about it and she put it very well. 15 minutes every friday for a kid to have a special book where they can write whatever they want. no rules, no marking, just fun, and getting lots of parents, grandparents and ca re rs lots of parents, grandparents and carers writing to me saying my kid used to love writing, but now they are so used to love writing, but now they are so worried about righting the wrong word, or their spelling or the handwriting, that they no longer even want to put pencil to paper. so creativity is very high on her agenda, as is the idea that every child should own their own book. this is something you might like as well. every child should have the permission to put down a book they are not enjoying. we could all learn

from that, at any age! will gompertz, thank you. when william wordsworth came across a belt of golden daffodils in the lake district 200 years ago — he famously wrote a poem about it. today, would he be more likely to take a quick picture and share it online? the country's tourist attractions now have to appeal to a new generation of visitors — and become instagram—friendly. danny savage has been to find out more. visit somewhere special while living life through the lens. the power of social media is seeing a different generation heading to those special spots to prove they've been there. after all, the camera never lies. so we'll start in york, which has lots to see and loads of history. they took to the tower... john has started a bespoke instagram tour of the city, with the specific aim of getting in the right place for the best pictures. i think it is really changing the way people want to consume,

and the way people want to visit a city and particularly capture it very much in the present and share their adventure and share and create stories about what they're doing with people. having that tour that takes you to those locations where you can take those types of pictures is really, kind of, like, the goal. everyone at home wants to see them, our families are waiting for them, you get calls all the time like, "where are you now?" it's nice for them to be able to see. the name instagram, instant, so the moment we're there, they get to experience it at home too. a few miles down the road at castle howard, there's a frame to help you get the right picture. knowing the audience is the key here. it's absolutely essential that we engage with younger markets. places like castle howard are the lifeblood of the country's history and how we make it relevant for younger markets is really important for us. this was also the venue for a taiwanese pop star's wedding reception, and that's brought in thousands of visitors. saw the picture from

a popstar, a famous taiwan popstar from his app. his instagram? instagram. and he got married here? yes. and you saw the pictures? yeah, that's how we know castle howard. over at the unesco world heritage site at the lake district, there's a more cautionary note. everyone wants to take photographs and get them straight on social media so they can show their friends where they've been. you've got to get up high to get the top shots, and mountain rescue teams are worried. many people have fallen to their death or major injury. all you need is a gust of wind when you're concentrating on that photograph and you're over the edge. so you need to be careful and know what hazards are around you when you're taking selfies. one big question when taking selfies is, to have a selfie stick or not to have a selfie stick?

my daughters tell me that these aren't very cool, apparently, and i suspect that's because when you do use one, you get far more of the view and less of the pouting human. danny savage, bbc news. danny savage there on the latest selfie trend. now, india are playing new zealand at old trafford for a place in the cricket world cup final — with the winner taking on either england or australia at lord's on sunday. a short time ago new zealand were 1a9—3 with india yet to bat — our sports correspondent joe wilson has the latest. it's not just it's notjust where you're it's not just where you're from, it's where you're going. it's coming home! just one more win to get there. at times it felt like every square inch outside old trafford was being occupied by indian fans. but the new zealanders are here too. com pletely the new zealanders are here too. completely outnumbered, but it would be great. intimidated? no, indians

make a lovely crab. new zealand got the chance to bat first, but with one run scored... theirfirst man was out. the kiwis were not flying, but they were moving. captain kane williamson is often the key for new zealand and yes, that is four more. india selected ravi jadeja, partly for this. henry nichols deceived, a gap for the ball to squeeze through, and new zealand were 69—2. fans will a lwa ys and new zealand were 69—2. fans will always wa nt and new zealand were 69—2. fans will always want more. new zealand were taking the patient approach. not many risks and therefore not many big shots. this one crawled towards the boundary. even the indian fans seem the boundary. even the indian fans seem have something to cheer. maybe new zealand need their help. to set a meaningful total, new zealand had to ta ke a meaningful total, new zealand had to take some risks at some point. up goes, and there it it lands, safe. tense? well, take a quick look at the indian captain. joe wilson, bbc news, old trafford.

well, it's another good day for tennis fans. british number one johanna konta is back on centre court and later andy murray and serena williams are in the mixed doubles. and our correspondent david ornstein is there. this is the business end of the dominant, women's quarterfinals day. butjohanna konta is not the only attraction because watching on from the royal box are some of the england footballers who reached the semifinals of the recent women's world cup. earlier today, semifinals of the recent women's world cup. earliertoday, i semifinals of the recent women's world cup. earlier today, i caught up world cup. earlier today, i caught up with one of the lionesses, karen carney. definitely now we're going into the royal box. watching, you know, the games at wimbledon, it's amazing, really. we're really lucky and, you know, i'm honoured to be asked to be here and like you said, it's definitely changed over time to get this invitation to come to such a prestige event. is that a sort of measure of how the england women's team have captured the imagination

of the nation, that you're invited to something like this today? it sort of shows that you've touched so many millions of people over the last few weeks in france? i think so. i think more so that people are more excited at how good the tournament was as a whole and how well, you know, the lionesses played. we obviously didn't go to that final hurdle, but i think we did show a lot of heart, desire, passion and that's something that can resonate with the english nation. but i think even overall, the world cup, from all the games, has been such a massive success and to get 12 million people to watch our semi—final game, to have 60,000 people in the stadium, itjust shows how big the game's going and i keep saying it, how scary the game is going to be, we've got the olympics and the home euros. i think the home euros

is going to be unbelievable. and that's a credit to everyone involved in the sport. carney and her team—mates are in for a treat. serena williams, jo konta and andy murray later in the mixed doubles, a star—studded line—up indeed. david ornstein, thank you. let's check out the weather prospects. shame it is not the same everywhere. this was the scene in edinburgh a short while ago, damp and grey conditions. that is being repeated across quite a few parts of the northern half of the uk. i can show you the rain charts where the rain has been falling. northern ireland is starting to brighten up, but the rain is still across a good part of scotla nd rain is still across a good part of scotland and the rain is now working into the midlands and north—east wales. but it is a glorious day across parts of devon and cornwall. not quite as warm in shetland, but the sun is out. elsewhere, the cloud

sits in
