And a very stupid guy. A form of medicine called gene silencing is approved for use by the nhs doctors say the impact is amazing. This is huge. This is making a disease that was previously untreatable treatable and has the potential to make patientss lives dramatically better. The first study of its kind finds that most ethnic groups in the uk earn less on average than White British workers. And Johanna Konta britains last remaining hope for victory at this years wimbledon is fighting for a place in the semifinals. After weeks of intense debate within labour, Jeremy Corbyn has announced a significant shift in the partys position on brexit. Hes called on the next conservative Prime Minister to hold another referendum before taking britain out of the eu, and hes said that, in that case, labour would campaign for remain. But mr corbyn has not explained what labour would do if it won a general election and whether it would try to negotiate its own brexit deal with the european union. Our political correspondent, nick eardley, reports. Brexit has not been easy forJeremy Corbyn. The landscape for labour 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. Today, mr corbyn said the pm should put their plan to a referendum and labour would back remain. Any deal should be put to a public vote so people can decide whether they want to accept that position, or, as an alternative, to remain in the eu. Sometimes watching the labour partys brexit position evolve has been a bit like watching an oil tanker turn round. But in a meeting up there at the shadow cabinet, there has been a shift agreed. Now the party will say to whoever our 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 dont know what labour would campaign for in a general election and whether it would back remaining if it managed to get its own brexit deal. The next election will come when it comes. It may be in october, it may be next year, even 2022. I dont know. What youve gathered from this discussion is that we have a very large barty and a very Large Membership and many parts to our party and movement. We are going to decide what our position is going to be. We dont know whether we will have left the eu, whether we are in the eu, or in a parliamentary struggle. Right now, we have a very strong pre election policy that im proud of, our members will be proud, they campaigned for it. It has taken too long but hopefully we can go and campaign for it. Some wantJeremy Corbyn to go further. Brexiteers will accuse the labour party of ignoring the referendum result. But the party is now moving in the direction of backing staying in the eu, even if the journey isnt yet complete. Nick eardley, bbc news, westminster. Lets go to the houses of parliament now and speak to our political correspondent, jessica parker. How big a shift in Labour Party Policy is this . It is a really significant shift in as you know pressure has been building onJeremy Corbyn for quite some time, and particularly in the wake of those european parliamentary elections where the perception was that parties like the lib dems and the greens had a clearer message on brexit, they mocked up a lot of votes that labours mine should have been there. Jeremy corbyn shifting today. However, still some mystery over what would happen in the event ofa over what would happen in the event of a general election and a Jeremy Corbyn government. The challenge for labour could be that what they have clarified their message to some extent it might not be as Crystal Clear as per example the liberal democrats. Joining me is that labour mp hilary benn. What do you make of todays shift . that labour mp hilary benn. What do you make of todays shift . I welcome it. I think it is very significant indeed. It is not before time. We have got 14 of the vote in the european elections, people did not understand what our position was, and we lost more votes to the greens and we lost more votes to the greens and the lib dems than the brexit party because people did not know where labour stood. We are clear now that we are in favour of a referendum in all circumstances and we will the new Prime Minister, presuming it is borisjohnson, to put whatever deal he negotiates with the deal that the moment to the people in the referendum in which remain is on the ballot paper and labour will campaign for remain. Should there be a general election . Should there be a general election . Should there be a general election . Should there be a labour deal . What would happen then . As i understand it, the shadow cabinet took no decision about that. Its not good enough . If we have an election, we will have to be Crystal Clear, and if labour were to go into that election, saying, we are negotiating and we might be for brexit or might not be, afraid that will not wash. We will have to be absolutely clear, and if we are saying we are the party of remain, facing a Boris Johnson government if thats what we have in a couple of weeks time, we need to have the courage of our convictions in those circumstances and the general election because the chances of labour getting elected, given what happened in the european elections, would not be very good. And finally on this one, in terms of those concerns that a number of your collea g u es those concerns that a number of your colleagues have, especially in the midlands and the north, leave voters would punish up the balance box for increasingly shifting towards a remain position, what you say to them . We are three years on from the referendum. You can have all your sovereignty back and keep the economic benefits which never existed. Brexit involves choices. And to go back to the people is the compromise. We have the same, it will be a no deal brexit, which would be disastrous, on the other side we have those saying, cancel the referendum result. And the compromise position in the middle is to say, its the choice, if you want to say, its the choice, if you want to leave this is what it looks like and if you want to remain, and its up and if you want to remain, and its up to people to decide how to vote, it is not telling and want to change their mind, but if the british people have changed their minds, it would be onto leave if they have reached a different conclusion. The only way to find out to end the deadlock is ask them. Three labour peers including a former general secretary have resigned the labour whip today, saying the party is anti semitic, a claim that the labour party are strongly rejecting this afternoon, but what you make of this afternoon, but what you make of this latest development . this afternoon, but what you make of this latest development . I am very sad to hear this news. David cheeseman was a distinguished general secretary of the party, and when one yarn says they are resigning the labour whip or giving up resigning the labour whip or giving up their membership, i say, im sorry i hope you will come back one day, but undoubtedly we do have a problem with a very small number of members who it seems have engaged in anti semitic conduct, and the proof of that is the equalities and human rights commission. When we were in government, we established it, they are undertaking a formal investigation of the labour party, and this cannot be allowed to continue, we have to rid our party of people who engage in this behaviour and then start the long and slow process of winding back the trust of the jewish community, and thats what i want to see. Winning. Three labour peers announcing they are resigning the labour whip over this ongoing row over anti semitism, the labour party rejecting the criticisms of the party, it is the latest developments in the now very long running saga. President trump has stepped up his condemnation of the British Ambassador to washington, calling him a pompous fool and a very stupid guy whod been foisted on the United States. It follow the leak of e mails written by sir kim darroch, which described the Trump Administration as inept and dysfunctional. In his latest barrage of tweets, mr trump also said that theresa may had ignored his advice on brexit but that she had gone her own foolish way, leading to disaster. In the last hour, theresa mays spokesman said the Prime Minister has let sir kim know personally that he has herfull support. Our diplomatic correspondent, james robbins, reports. Thank you for your continued hospitality. The emir of qatar thanks donald trump at a white house dinner last night. Routine, you might think, except that britains ambassador, sir kim darroch, was not there, originally invited. Then warned off attending by the administration after sir kims highly critical description of his administration as dysfunctional, faction riven, 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 mays full faith and support in sir kim. So put those two things together and, from his point of view, youve got a toxic combination which has led to this shower of tweets. And the president s latest tweets are incendiary, even by his own standards. The president goes on. Its extraordinary to see the president attacking her majestys government in this way. The us in the uk have had policy disagreements many times over the years and we have always managed to work them out and the clubby in the spirit of cooperation and shared values, but this kind of personal attack is something i have never seen before. Amicably. Sir kim darroch seems safe in his post as ambassador. Theresa may has repeated her support for him. And in whitehall, a cross government leak inquiry is now 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 very great care across a couple of years to do it to fillet the juiciest bits from these diplomatic telegrams, package them up and hand them over to a journalist. I suspect its going to be quite hard to find out who that person is. Uk relations with the white house are intensely strained. The president himself is rejoicing in the fact that theresa may will soon be gone. Her successor will have to decide how to repair the damage. James robbins, bbc news. We can now talk to nancy soderberg, a democratic former White House DeputyNational Security advisor and former un ambassador. When the president says that he is not dealing with the British Ambassador, do you see this as an attempt by the president to dictate who we have in washington and had to dictate British Foreign policy, to some extent . I honestly would not read more into it the president s ego, and he is lashing out in unprecedented ways. The British Ambassador is the cog in the wheel that everything that happens in washington, from the dinners to the tennis to the invitation at the residents or the embassy there. The ambassadorfrom residents or the embassy there. The ambassador from the uk residents or the embassy there. The ambassadorfrom the uk has to have the goodwill of the administration, so the goodwill of the administration, so the impact of this will new to his ability to function, and he will sadly have to be replaced. They will probably gracefully waiting to the new pm is in place, but the fact that an ambassador said what eve ryo ne that an ambassador said what everyone in washington are saying and it leaked, it is very u nfortu nate. And it leaked, it is very unfortunate. Theresa may is right to stand up to him but this is not sustainable. You talk about this being unprecedented. During the wikileaks being unprecedented. During the wikilea ks scandal, there being unprecedented. During the wikileaks scandal, there were american ambassadors around the world whose documents were leaked, what happened to them . Many of them resigned, but they did not get into a personal twitter spat with the head of state, that is the difference here. Normally these things would be handled quietly through back channels, they would be told they were not happy with the statements, it would be handled in a back door way, and they would be a graceful way to try and change the ambassadors, but to be attacked by the president in such vicious terms is what is unprecedented about this. It is unfortunate. So kim has not said anything the rest of the diplomatic corps are saying privately amongst themselves and these dinner tables around washington, but the fact it is now attributed to him is right to investigate the leak, make sure the ambassadors of the future can do their reporting in a frank way that they are not worried about getting leaked. The tragedy is, will be ambassador have to wait until he is back to london to give a report . We dont want to have that situation. Governments rely on frank assessments such as governments rely on frank assessments such as the one so kim was relying, and the fact we have a president that lashes out and neuters his ability to function as u nfortu nate neuters his ability to function as unfortunate on every level. To relations between washington and london, we have seen in his latest twitter tie raid the president criticising theresa may and her brexit policy is foolish and a disaster, and in london, theresa may has said. Would downing street have said theresa may has personally assured so kim that she has his full support. She is a shortterm Prime Minister. She is right as any Prime Minister. She is right as any Prime Minister would be to stand by the ambassador when he has done nothing wrong. He has done hisjob and done it well, he is well respected in washington. On principle, she has to stand by him, but on the other had the new government coming in for wa nt the new government coming in for wantan the new government coming in for want an ambassador who has access to the white house and can do itsjob, and that will necessitate a graceful rotation. He has been there since january 2016 so this can be done gracefully once there is a new resident of ten downing st, and hopefully they will give him a good post going on. Very good to talk to you. Former un ambassador, thank you very much indeed for being with us. My very much indeed for being with us. My pleasure. Lets bring you some breaking news from the house of commons. Mps have been debating a series of backbench amendments relating to the Northern Ireland executive, and they have just voted in favour of extending same sex marriage to Northern Ireland, but thatisif marriage to Northern Ireland, but that is if no Northern Ireland government is formed by the 21st of october this year. The proposalfrom a labourmp was october this year. The proposalfrom a labour mp was approved by 383 votes 73, a huge majority of 310. But if and when the Northern Ireland executive is restored at stormont, it could prove all reverse that change. This is a Development Concerning same sex marriage in Northern Ireland, mps voting to legalise same sex marriage in Northern Ireland. But that is unless the devolved government has been restored by the 21st of october. We will talk to our island correspondence in the next few minutes, just to talk a little bit more about how significant that vote is for Northern Ireland. Well, the story we were discussing is likely to be raised in tonights tv debate between the two conservative leadership candidates. Our chief political correspondent, vicki young, is in salford, where that debate will take place. What are the issues that will come 7 what are the issues that will come up . A crucial question about the British Ambassador, will that be debated . Of course borisjohnson is pretty close to president trump. That is sure to come up tonight, and it is particularly interesting because jeremy hunt is it is particularly interesting becausejeremy hunt is the current foreign secretary, and borisjohnson as his predecessor, and its a huge dilemma for them because the nature of Donald Trumps tweets was so personal, the criticism of theresa may, one of americas closest allies, not a hostile state, are extraordinary even though we have grown used to donald trump taking to twitter and lashing out. This is at a different level. In the last couple of moments, jeremy hunt has responded directly to donald trump on twitter. He says this, friends speak frankly, so i on twitter. He says this, friends speakfrankly, so i will. These comments are disrespectful and wrong to our Prime Minister and my country. Your diplomats give their private opinions, and so do ours. You said the alliance was the greatest in history, and i agree, but allies need to treat each other with respect as theresa may has a lwa ys with respect as theresa may has always done with you. Ambassadors are appointed by the uk government, in ifi are appointed by the uk government, in if i become Prime Minister our ambassador stays. So a very strong response therefrom jeremy hunt. People will want to tonight how the candidates play their reaction to this because do they defend the Prime Minister, their colleague, is the ambassador we have in washington . Or will they be concerned about the future relationship with the president of the united who of course is erratic, it is hard to know what he will do n
