Britains ambassador to washington has resigned, following the leak of his confidential emails in which he described the Trump Administration as inept and dysfunctional. President trump had denounced sir kim as stupid, wacky and a pompous fool and said the white house would not deal with him. The ambassador now says its impossible for him to carry on. Theresa may told the commons its a matter of great regret that hes resigning. Our World Affairs correspondent Naomi Grimley reports. Sir kim darroch, just last month, during Donald Trumps state visit. He was one of the key aides to facilitate the president ial stay in london. But a series of leaked memos in which he branded the president inept and insecure put paid to that close relationship and resulted in the most extraordinary attack from the most extraordinary attack from the president on twitter. Mr drummond had called the uk ambassador wacky, a very stupid guy and a pompous school. Yesterday, sir kim was visibly frozen out of a reception at the white house which he was due to attend. And so, today, he was due to attend. And so, today, he said he felt he should go. Theresa may had already made it clear she supported him continuing in his role, but, in the end, she accepted it was the diplomat himself who wanted to go. I have told him that it who wanted to go. I have told him thatitis who wanted to go. I have told him that it is a matter of great regret that it is a matter of great regret that he has felt it necessary to leave his position as ambassador. The whole cabinet rightly gave its full support to sir kim on tuesday. Jeremy corbyn. Thank you, mr speaker. I too regret the resignation of Sir Kim Darroch. I think the comments made about him are beyond unfair and wrong. I think he has given honourable and good service and should be thanked for it andi service and should be thanked for it and i think the whole house should join together in deeply regretting the feeling he has obviously got that he must resign at this moment. Critics of borisjohnson, the favourite to be the next Prime Minister, will say he didnt help sir kim by refusing last night to back him staying in washington until the end of his ambassadorship. Even though he is a former foreign secretary. This episode will trigger soul searching in the Civil Service about loyalty to respected officials in an age of leagues and wider rancour over britons position on the world stage. Naomi grimley, bbc news. In a moment, we will speak to our correspondent in washington, nick bryant, but, first, lets speak to our Diplomatic Correspondent james landale, who is at westminster. Lets just pick up on what we were hearing in that report from Naomi Grimley about the role of Boris Johnson and questions about what he said about this last night. Yes, what is being explained here and widely expressed by people across whitehall is that the final straw for sir kim came when he was watching the tory leadership contest last night, he saw watching the tory leadership contest last night, he saneremy hunt support him and give him his backing and he saw borisjohnson refused to give his backing and that made up of sir kims mind that it was not possible for him to carry on. If you dont have the support of the white house and it turns you do not out you do not have the support of who could be Prime Minister in a few weeks time, the game is up and you have to go. James, thank you. Lets go to nick bryant in washington. This follows a thai rate of insults on twitter from the president directed at sir kim. Will President Trump feel that he has got his man . President trump could wake up this morning and think he has veto power over who the uk appoints as its ambassador in washington. And it wasnt so much those insults, that mockery, that it did for Sir Kim Darroch, it was the president s digital edict on monday night about his administration would no longer deal with him, that he would be persona non grata at the white house and that came into immediate effect. There was a banquet on monday night that Sir Kim Darroch was this invited from. The next day, he was supposed to accompany liam fox, the International Trade secretary, in a meeting with a banker trump at the white house. Sir kim himself decided he wouldnt go along ivanka drum. It was not certain he would be welcome. It was very clear he was frozen out by the Trump White House and foran frozen out by the Trump White House and for an ambassador, accesses everything and when that access is denied, as sir kim said in his resignation letter, it becomes impossible to do the job. I resignation letter, it becomes impossible to do thejob. I mean, on a broader point, i think this shows at the moment the kind of asymmetry of the special relationship. There has never been parity in the special relationship, it has never been a relationship, it has never been a relationship of equals, even in the days of churchill, who actually coined the phrase the special relationship after the war, but, at the moment, it seems particularly lopsided, especially in this time of brexit, when britain is leaving the european union. America knows that britain is fairly isolated right now internationally. It has the power and donald trump has wielded that power over the last few days. Nick, thanks very much, nick bryant in washington and james landale, our Diplomatic Correspondent at westminster. The former Prime Minister sirjohn major has said he would go to court to stop parliament being suspended over brexit. Sirjohn says proroguing the house of commons would drag the queen into a constitutional crisis. Borisjohnson the front runner in the tory Leadership Campaign has refused to rule out suspending parliament to ensure the uk leaves the eu by october 31st. Our Political Correspondent nick eardley reports. One of these men will be Prime Minister two weeks today. Brexit will be their key challenge, but will be their key challenge, but will they be prepared to suspend parliament to force it through . My answer to that is no, how about you, boris . Im not going to take anything off the table, any more thanl anything off the table, any more than i am going to take no deal of the table. That is hugely controversial, leaving open the idea of sending mps home to stop them blocking a no deal brexit. It splits the conservatives and many in the country. This former Prime Minister says it would cause a constitutional crisis involving the queen. Says it would cause a constitutional crisis involving the queenm says it would cause a constitutional crisis involving the queen. If her first minister asks for their permission, it is almost inconceivable that the queen will do anything other than granted. She is advised by her first minister, and she is then in the midst of a constitutional controversy that no serious politician should put the queen in the middle of. Now, i think this is completely and utterly against parliamentary tradition and against parliamentary tradition and against the way in which our government should work. And he is threatening to take legal action to stop it happening. The queenmy decision cannot be challenged in law. The Prime Ministers advice to the queen can, i believe, be challenged in law and ifor one would be prepared to go and seek judicial review to prevent parliament being bypassed. Brexit supporters dont want to send mps home to force through no deal. Many say it just wont home to force through no deal. Many say itjust wont get home to force through no deal. Many say it just wont get to that stage but by keeping it on the table, borisjohnson risks a remarkable political row over the road in the supreme court. Just imagine the prospect of a former tory pm taking the current tory pm to court over his key policy. It shows just how deep splits in the conservative party run. Some say suspending parliament has to remain an option, the uk must stick to its promises and deliver brexit in october, no matter what. But others are horrified by the idea and many of mr johnsons own supporters are keen to play it down. We need to deliver on the result of the referendum because we are a democracy and we follow the results of votes, and then we need to move forward in a way that can bring the party and the country together and, in bring the party and the country togetherand, ina bring the party and the country together and, in a way, what sir john has said today isjust together and, in a way, what sir john has said today is just another example of how desperately we need this country to start to come together again. Whatever happens, in the next few months, there will be an almighty brexit battle here and parliament remains divided, our politicians are struggling to find a compromise. But if the new pm locked them out, it could prove the most controversial move yet. Nick ea rd ley, controversial move yet. Nick eardley, bbc news, westminster. Lets speak to our assistant Political Editor norman smith at westminster. So, as nick was saying, you could theoretically at least have the prospect of a former tory Prime Minister taking a current tory Prime Minister taking a current tory Prime Minister to court. It is an extraordinary prospect but i think it just unravels extraordinary prospect but i think itjust unravels this contest in the sense that, so far, it has been a nicely nice contest but now the animosities, the tensions have been laid bare. We saw a bit of it last night, some of the very personal attacks byjeremy hunt on Boris Johnson, suggesting he is putting his own personal interests before that of the country. Now we have sir john major raising this extraordinary, unprecedented prospect of a former Prime Minister from the same party taking a serving Prime Minister, presumably Boris Johnson, to court. We have never, ever seen anything like that before and although one source close to borisjohnson said sirjohn had gone bonkers and driven stark, staring mad by brexit, legal opinion suggests that sirjohn may have a chance and that theresa may herself was thwarted in her brexit plans by the courts after they stopped her triggering article 50 without the approval of parliament. It also opens up an entirely new front in the campaign to stop no deal, leaving the eu without any sort of agreement. So far, mps have tried, without any success, on obscure parliamentary procedures to stop no deal. Now sirjohn major appears to be hoping it is the courts who will stop no deal. Norman, thank you very much. Norman smith, ourassistant Political Editor. A scathing report says the governments has a ramshackle, dads army approach to Climate Change. The committee on Climate Change, which advises the government, says it is shocked ministers are failing to cut emissions fast enough. It warns that action to prepare homes and businesses for a hotter world is less ambitious than it was a decade ago as our environment analyst Roger Harrabin reports. We are in the summer period and, as i have been saying throughout the whole of last month as well, we need to drink more fluids. Heat can kill elderly people. In this exercise class, they work hard to keep cool. I find it difficult to drink a lot of water but i do know how very important it is, because it can have devastating effects if you get dehydrated. Actually, i go in the garden a lot and the windows are all open and we have ice cream. The world has already overheated by one degree, and it will get hotter. This care home is already adapting. Staff have been on extra alert to be more vigilant with offering fluids and hydrating foods, particularly fluids little and often. So, these people are fine but the report says policies are needed to protect the whole population, as the climate hots up. Care homes are a particular problem because of the uks increasingly elderly population. But many hospitals are overheating too. Even modern flats are sometimes being built with ventilation that is completely inadequate for the sort of temperatures we are likely to expect. Climate heating will affect property as well as people. The docks at immingham in humberside are vulnerable to the inevitable rise in sea level. The Committee Says ministers must get a grip. This really is not good enough. There is an emergency to reduce the hazard, to reduce the Greenhouse Gas emissions. But actually we are seeing the Climate Change. Even if we are on the 1. 5 degrees path, the climate is going to go on changing, we are going to see more severe weather. The 2018 summer is going to be, by 2050, a normal summer. The report says only the power sector is on track to meet its targets for cutting the emissions that are fuelling global heating. Global transport emissions have barely dropped. There are too few charging points for electric cars, the Committee Says. People need to get out of their cars and onto public transport, walking and cycling. Then there is flying. Ministers are increasing aviation, but the worlds most popular environmentalist says air passengers do not pay the cost they impose on the climate. If you cost that, you would see the tickets are extraordinarily cheap. Dealing with these problems means we have got to change our life style. The government insists it wants to lead on Climate Change and will produce new policies. The Committee Says it wants deeds, not words. Roger harrabin, bbc news. Its been more than a year since the United States pulled out of the Iran Nuclear Deal and re imposed sanctions on the regime in tehran. Now iran is putting pressure on britain and other european nations that were co signatories to the deal. It says theyve failed to honour a promise that they would compensate iran for the losses its suffered as a result of fresh american sanctions. Irans ambassador to the un has been speaking to the bbcs Barbara Plett usher. For the time being, we are in the deal and we invite others to stay in the deal. Apparently, besides the us, the europeans have not been up to the job and they have not honoured all the commitments, all their commitments, up to now. But what more are you expecting the europeans to be able to do . They cannot give you the economic benefits of the deal because the us sanctions are too strong. When President Trump decided to get out of the nuclear deal, we were approached by three european leaders, encouraging us, insisting iran not to get out of the nuclear deal and they promised us to do exactly what they were supposed to do, to compensate what we have lost as a result of the us withdrawal. So it is not acceptable to us to see that the europeans are not honouring their commitments. So what happens if they are not able to compensate you in the way you want . Do you keep raising the level of uranium enrichment . For the time being, we are in phase two. If nothing happens in the course of the next 60 days, i think we will have to go to the third phase and the developments of the third phase are not known yet, but when it comes to that, we will announce what we are going to do. President trump nearly bombed iran last month. Do you think he wants a war . I dont think that President Trump wants a war with iran, but those who are close to him, definitely, they are looking for a conflict between iran and the United States and whatever they have been doing is exactly in line with what they said. Does iran want war . No, we do not want a war. We do not want to have a war with the us or anybody else. It is not in our interests to see fire being spread in our neighbourhood. A commander of the revolutionary guard has just recently said that us regional bases and aircraft carriers are within range of uranium missiles and if they make a mistake, if the americans make a mistake, these will be destroyed. That sounds like a threat. No, it is not a threat, it is an expression of a fact that if we are being attacked, definitely we will not just sit on our hands. We will respond and that is not going to be helpful to anybody. The Iranian Ambassador to the United Nations speaking to the bbcs Barbara Plett usher. Our top story this lunchtime. Britains ambassador to washington resigns after the leak of his confidential memos criticising the Trump Administration. And we are live at wimbledon where the mans quarter finals live at wimbledon where the mans quarterfinals are live at wimbledon where the mans quarter finals are under way. Coming up in the sport in the next 15 minutes on bbc news. The Manchester United maanger ole Gunnar Solskjaer says that the media have an agenda against their record signing paul pogba and that he is a great professional. Roger federer and rafael nadal could set up their first wimbledon meeting since the epic final in 2008, when they headline the mens quarter finals this afternoon. Eight time champion federer plays japans eighth seed Kei Nishikori in the quarter finals, while nadalfaces sam querrey. Also in the last eight of the mens singles, Novak Djokovic will take on belgiums 2ist seed david goffin, while Roberto Bautista plays guido pella. Lets get all the latest from our Sports CorrespondentDavid Ornstein who is at wimbledon this afternoon. This is always one of the most enthralling days of the championships and to see the big three, federer, Rafael Nadaland djokovic, still going strong underlines the extraordinary nature of this year in mens tennis, an era that many believe is the greatest of all time. Still hoping to be a part of that is andy murray. His recovery from hip surgery appears to be going well and he will be back on court with Serena Williams later on today. Forjohanna konta, her wimbledon is overfor forjohanna konta, her wimbledon is over for another forjohanna konta, her wimbledon is overfor another year, forjohanna konta, her wimbledon is over for another year, and the fallout from her defeat and the press co nfe re nce fallout from her defeat and the press conference that followed it, which included an exchange with a journalist, and my colleague lee mckenzie topped up with the british captain to talk about it. I think its just great to see him back enjoying it and competing, which is something he has missed. Its notjust that, he enjoys being around tournaments, being around other players and seeing everybody. You saw him earlier today doing his warm up before his practice, he likes that sort of routine and being amongst it. Watching him on court with serena you know thats a big deal for both players and the emotions are riding high. Ive absolutely loved watching them so far. Johanna konta had a great win against petra kvitova, it didnt work out yesterday for her and there has been the subsequent backlash from that press conference. What do you make of all that . Well, the overriding thing is she has got to another quarterfinal of a slam off the back of what happened in paris, the brilliant run as well in rome. Herform and confidence isjust going up and up and up. Over the last 18 months she is just improving all the time, she has got a great coach around her and its normal to get asked certain questions, but i think she was right to bat it back and concentrate on the good things that are happening to her tennis because there is an awful lot to be positive about johanna konta. First up on centre court is Novak Djokovic, the defending champion, against david goffin of belgium, who is playing in his first wimbledon quarterfinal. They are going with serve in the first set. Behind me is Roberto Bautista agut, the only man in the mens singles to drop a set, and he is a breakto in the mens singles to drop a set, and he is a break to the good against guido pella. On centre is Roger Federer against Kei Nishikori. On court number one is rafael nadal, and many people think he will go all the way this year. Andy murray and Serena Williams are third on court two in round three of the mixed doubles and that should be around 2 30pm or three oclock, and the crowd a re 2 30pm or three oclock, and the crowd are certainly looking forward to that. David, thank you very much indeed. Lets stay with tennis. Lets stay with tennis. With the likes of the long established williams sisters, and now teenage sensation coco gauff leaving a big impression in her wimbledon debut, its clear theres no shortage of talent from black and ethnic minority backgrounds in the tennis world. And its hoped their success will inspire a whole new generation to get serious about the sport, as nomia iqbal reports. 0h coming to wimbledon is definitely a moment to capture, especially for these young girls. You do come here and sometimes you do feel like an outcast. You come here and you see, like, the people that are normally here and they dress a certain way and we are not dressed that way. But it doesnt matter because at the end of the day everyone is here for the same reason, to watch good quality tennis. Free girls they are from east london and are aspiring tennis coaches. They are part of a project with the Lawn Tennis Association which aims to encourage people from disadvantaged backgrounds to get into the sport. Seeing people that are our age like coco and its really inspiring, like, to see that people are actually achieving their goals at such a young age and it gives us someone that we can actually relate to. Cheering. American teenager coco gauff has been the big star of the tournament which critics have often seen as too white and too middle class. Lta says it wants to open it up to everyone. Weve also got great role models, you look at someone like jay clark. We have got pauljubb, 19 years old, Heather Watson of course. Weve got a whole bunch of players coming through from a range and of a diverse backgrounds. Someone has to lead the way, someone has to show that it is possible and the father of venus and serena, richard williams, was the first black father that showed that in a white world there could be black women performing and at the highest level. But getting to that level means a big financial investment. I hope that we can afford more tennis facilities for places like hackney where weve got this community where people can, if they want to, develop, so come at a young age and develop into professional tennis players. So far, 10,000 young people from diverse backgrounds are involved in the ltas initiative and these girls are no longer ruling out tennis as part of their future. Nomia iqbal, bbc news. Now, if youre feeling unwell and havent got time to see a doctor, how about asking alexa . From this week, people will be able to get medical advice from amazons Voice Assisted Technology. They can ask questions such as, how do i treat a migrane . And what are the symptoms of flu . And alexa will then automatically search the nhs choices website for answers. But critics have condemned the new service as a Data Protection disaster waiting to happen. Our health correspondent, nick triggle, reports. Alexa, what are the symptoms of chickenpox . According to the nhs website, chickenpox starts with red spots. The popularity of Voice Assisted Technology is growing and now the nhs is looking to harness its benefits. From this week people using their amazon alexa device to search for health information, or to ask medical questions, well get that information drawn directly from the nhs choices website. But will this be enough to convince people not to go to their gps or pharmacists . I have an alexa and she rarely hears me right so i probably wouldnt, i probably would just google on my phone. I think if its for something less life threatening, like the common cold and things like that, i would listen to it, but if im risking my life i wouldnt be happy, id probably go and see my gp. I probably wouldnt feel confident at all because even just googling my symptoms through my phone i dont trust it at all. The department of health and social care in england accepts there will be limits to what it will be used for but believes it could be helpful, especially for people who may struggle to access the internet in the traditional way, such as older people or those who are blind. People already ask alexa medical questions, that happens in millions of homes across this country and i want when people ask those questions for them to get the very best advice. Here is your flash briefing. Doctors agree there is potential in using Voice Assisted Technology in this way, but they have concerns. The beauty when you see a Health Care Professional is they are not just listening to the words that you say, they are looking at you as a whole person. They have your background to hand, the medical notes, and they can evaluate so many other elements. And of course youve got the years of Clinical Training behind us which helps us as well. And this could be just the start. The government is also in talks with other companies about setting up similar arrangements. Nick triggle, bbc news. Its been quite a morning at the cricket world cup semi final at old trafford. Resuming after yesterdays rain delay, new zealand finished on 239 for 8, and then had india in early trouble, reducing them to 5 for 3. Jo wilson has been watching the action. The manchester puddles will dry long before the enthusiasm wanes. India the method was if you had a ticket for yesterdays rain disrupted play, you could use it again today. Now, one thing the indian fans have learnt during this world cup is you cant rely on the english weather. Well, iam neutral but you can rely on the indian batsmen. Virat kohli. Cheering. And rohit sharma. Five centuries in the world cup already, rohit sharma couldnt fail. Oh, yes that is the sport for you. Gone for one yes, really. Still, there was virat kohli. What . Lbw. Him, too . India only needed 240 to beat new zealand. They were 5 2. No, 53. Rahul gone. Sensation, disintegration. The great batting nation unravelling. Heres our old friends in a different mood. Credit new zealand for their bowling, theirfielding. 0h, he caught it he caught it. Jimmy neeshams catch to get rid of Dinesh Kartik was almost unbelievable. How can you hold that and then drop this . An escape for pant, but new zealand loomed. We will get you soon. But someone had to stand and resist. A four from pant, a roar from the crowd. At this stage, they would take anything. But now look at this. There is a fielder out there. Right there. And the fifth man gone and new zealand, oh, the final is near. Jo wilson, bbc news, old trafford. Just to update you, a short time ago india were in more trouble at 97 6. Time for a look at the weather. Heres matt taylor. The weather is behaving itself at old trafford today, as it is for many. When the sunshine comes through, it is feeling increasingly humid. That will have a consequence later. It is not completely dry everywhere. Early showers in Eastern England are clearing away. A few showers developing in west wales. A few showers in Northern Ireland and scotla nd few showers in Northern Ireland and scotland and they will become heavier this afternoon. In eastern scotla nd heavier this afternoon. In eastern scotland and Northern Ireland later on there could be the odd rumble of thunder. Most places staying dry and that sunshine boosts the temperatures. 26 or 27 in the south and in the high teens in scotland and in the high teens in scotland and Northern Ireland. There could be some storms in eastern scotland to end the early evening rush hour, the same in Northern Ireland
