Mrjohnson has already promised to deliver brexit by october the 31st the president of the Eu Commission says he is looking forward to working with him and President Trump has already congratulated borisjohnson saying he will be great. Well have all the latest from here in westminster and well be getting reaction from across the country and from brussels. Also this lunchtime the uk prepares for a heatwave as temperatures climb well above 30 degrees this week and coming up on bbc news, Jimmy Anderson is out of englands only warm up match for the ashes. They play ireland tomorrow but anderson has been struggling with a calf injury. Good afternoon and welcome to bbc news at one. So now we know and in the end there was no great surprise. Boris johnson was favourite to win from the start and now hes been voted in as the new conservative leader. He will officially take office as Prime Minister tomorrow after a meeting with the queen at buckingham palace. Borisjohnson gained around double the votesjeremy hunt did from conservative party members. In his victory speech, mrjohnson promised to unite the country and deliver brexit by the deadline of 31st october. But hes already seen some ministerial resignations and there could be more as several cabinet members have already said they cant support his do or die pledge to leave the eu. Iain watson has our first report. He worked in first but finished second, jeremy hunt was decisively defeated by borisjohnson. For many, the foreign foreign secretary was the foreign foreign secretary was the face of brexit, the mop top figurehead of vote leave and that probably appealed to the two thirds of conservative members who gave him their support. He said hed take britain out of the eu by the end of october and his acceptance speech was a cocktail of optimism and humour with the slightest dash of detail. We note the mantra of the campaign that has just gone by in case youve forgotten. You maybe have. It is deliver brexit. Unite the country and defeatJeremy Corbyn. And that is what we are going to do and i know some wag has already pointed out, deliver, unite and defeat was not the perfect acronym for an Election Campaign since it spells dad but they forgot the final e my friends, for energise. He seems to have a ready united his family though some have very different views on brexit but he romped through some of its other policy ambitions as well. We are once again going to believe in ourselves and what we can achieve in like a slumbering giant we will arise and lose the guy ropes of negativity with better infrastructure, more police and fantastic full fibre broadband sprouting in every household. The announcement of the new conservative leader was made here but the real challenges begin tomorrow when he moves just around the corner into downing street. Borisjohnson has said he will take us off the hamster wheel of do as he calls it, and get britain out of the European Union by the end of october. If he doesnt do that his time in downing street may be limited, if he does but without a deal he will be facing notjust the opposition but the unofficial opposition, senior members of theresa may s government who are prepared to rebel against him. Good morning. This is one minister who wa nt to morning. This is one minister who want to serve under borisjohnson, david gauke and his colleagues who opposed no deal have been dubbed the awkward squad. There is a clear majority in the house of commons that doesnt want to leave the eu without a deal, i think that will become very clear in the autumn, that will be underlined in the autumn. I think there may well be ways in which parliament finds an ability to make it clear what it thinks and that is binding upon the new Prime Minister. And the Education Minister anne milton resigned today, she was concerned that britain could leave the eu with no deal. I wish the new Prime Minister well in his negotiations with the eu but i have always had grave concerns about leaving the eu without a deal in place. But one prominent borisjohnson without a deal in place. But one prominent Boris Johnson supporter was rather looking down on those who choose to criticise him. There is no scope now for Self Indulgence and individual mps expressing their own views stop for the conservative party to deliver for our country we have to unite, have to come together. The future is uncertain for larry the downing street cat and indeed for the country. The new Prime Minister have a has a wafer thin majority even with Northern Ireland has mike dup on side. Boris johnson moves in here tomorrow, its not clear how long his tenure will last. Lets speak to our assisted Political Editor norman smith in downing street for us. Hell not get much of a honeymoon if one at all . No, ithink much of a honeymoon if one at all . No, i think thats true. Although im tempted to say despite the sort of hype of today, the moment of history, it was a day of few surprises in the sense that Boris Johnson one, and he won big time and then immediately fired up the Boris Johnson optimism boosters. Pledging to dispel negativity and pessimism to dispel negativity and pessimism to energise the country. So far, so familiar, that is borisjohnson, the party darling, the Conference Hall act but now we find out who the real borisjohnson is, act but now we find out who the real Boris Johnson is, who act but now we find out who the real borisjohnson is, who borisjohnson the Prime Minister is because there is no hiding place in downing street. And we are going to find out very soon street. And we are going to find out very soon whether he is the great unifier, whether he can bring his fractured Party Together and crucial to that, will be how far he brings different wings of the party into the cabinet or whether he surrounds himself with true brexit believers. And secondly, we are going to find out what sort of the brexiteer Boris Johnson is, is see the brexiteer of the Leadership Campaign, the do or die brexiteer, the man ready to eye ball die brexiteer, the man ready to eyeball the eu over no deal, to declare theresa may s deal dead or as some remainers hope, will he begin to trim away from that, will there be a more nuanced approach, or maybe he will seek to gravitate to a deal noti million miles from that of theresa may . We dont know but we are going to find out because for so much of his political career, Boris Johnson has been able to hide, if you like, behind the good humour, the bluster, the buffoonery. Now the borisjohnson, the the bluster, the buffoonery. Now the Boris Johnson, the real the bluster, the buffoonery. Now the borisjohnson, the real Boris Johnson, will have to stand up. Norman smith, thank you. Borisjohnson will face an overflowing inbox when he takes office tomorrow with brexit on top of that pile. With the deadline looming on october 31st, mrjohnson will need to build a new relationship with the European Union to ensure the best possible exit. Our europe correspondent Damian Grammaticas is in brussels. Weve already had some reaction the eu. What have they been saying . We have, and he doesnt have long to build that relationship, jean claude juncker, is out of brussels but through a spokesman he said today he congratulates borisjohnson on his appointment, he wants to work with him in the best way possible and crucially, the man who will have to be at the other side of the negotiating table, Michel Barnier, tweeted within minutes of the announcement of the result, this is what he said he means the guidelines from the eu is in national leaders. That is interesting and important because Michel Barnier reiterating for the eu has said throughout, the Withdrawal Agreement as it stands, theresa may s agreement it is sometimes called, is what the eu is sticking to thats a great, the eu says between the eu and the uk, not mrs may, and is the product of gravity, this is where the final solution has come to rest but where there is room for manoeuvre, on the political declaration, that is the non binding second document that could be reworked, the eu says. The problem for mrjohnson is that doesnt go nearly as far as what he has been promising in his Leadership Campaign, to scrap the backstop, the irish backs up entirely. So the question for the eu side is, what sort of ask is borisjohnson going to come with, what sort of team is he going to surround himself with, what sort of majority can he promise backin what sort of majority can he promise back in london to get something through parliament because the crucial thing is the eu will look at here is what is mrjohnson asking for, is it something acceptable to be eu . If its not, if its a big change to the Withdrawal Agreement it sounds like there will be no agreement on that. Can he get it through parliament is the second thing . They will listen carefully to the sorts of noises youve been hearing there about the opposition to the uk leaving without a deal, crashing out at the end of october, the eu very aware of that as well. They will wait here to see what mr johnson comes with and asks for. Damien, thank you. Lets get the view from around the uk with our correspondents in Northern Ireland, scotland and wales. As weve been hearing the most important challenge facing the new Prime Minister is brexit and in particular trying to avoid a hard irish border. Lets speak to emma vardy in belfast. The issue of the backstop has been one that has plagued theresa mays term how will the new Prime Minister tackle this . Absolutely, borisjohnson taking the topjob has huge implications for the island of ireland, those arrangements theresa may negotiated over the irish border they are effectively dead with borisjohnson starting afresh saying he will go back to the eu to try and renegotiate something different. But of course, the challenge remains exactly the same. How do you take one part of this island out of the eu club, put Northern Ireland into a different trading regime and yet continue to allow businesses both north and south of the irish border to keep trading seamlessly, as theyve always done for many years, without the need for stops and checks on the irish border . Theresa may had agreed to the backstop which could have meant Northern Ireland staying more tightly bound to eu rules, borisjohnson staying more tightly bound to eu rules, Boris Johnson wants staying more tightly bound to eu rules, borisjohnson wants to go back to the eu, convince them to ditch the backstop and site this can be sorted out later in a free trading agreement but the problem is the eu has already repeatedly said no to this would seemingly puts us all on course for a no deal brexit. Here there have been huge warnings for the potential of thousands of job losses especially in the republic of ireland if there was a no deal brexit, potentially businesses north and south of the border perhaps becoming an viable overnight. Boris johnson supporters would say thats all scaremongering, the irish border can be sorted out through technology and trading deals but until there are some firm a nswe is but until there are some firm answers there will be a lot of apprehension here for many businesses about the new Boris Johnson era head. Emma, thank you. A no deal brexit could trigger another Scottish Independence referendum. Lets speak to lorna gordon in glasgow. How can the new Prime Minister avoid a break up of the uk . Well, the power to have a referendum lies with westminster. But nicola sturgeon, the Scottish First minister has expressed a wish for a Scottish Independence referendum, a second referendum, in 2020, shes been talking in the last few minutes, she warned borisjohnson that he should be in no doubt about the strength with which she and others will oppose the threat of a no deal brexit. Remember a majority of people here in scotland voted to remain as part of the eu and there is some polling to suggest leaving the eu without a deal would push support for independence up to 60 . Borisjohnson support for independence up to 60 . Boris johnson didnt mention scotla nd Boris Johnson didnt mention scotland in his comments this morning, but he will be alert to the dangers, hes talked about adding the title of minister to the union to that of Prime Minister, setting up to that of Prime Minister, setting upa union to that of Prime Minister, setting up a union unit to look at every policy through the prism of devolved nations. Hes also talked about visiting scotland and the nations within the first few days of taking office but its notjust politicians who are fighting this front, trying to stop a no deal brexit. Here in scotla nd to stop a no deal brexit. Here in scotland they are also trying to do it through the courts, across a cross party it through the courts, across a Cross Party Group of politicians are seeking a ruling from the court of session, a ruling advising that the Prime Minister cannot lawfully advise the queen to suspend parliament which is a strategy which mrjohnson has talked about in order to push through a no deal brexit. We expect that to progress through august. Lorna, thank you. And what about the view from wales, where theres a by election in nine days time . Sian lloyd is in cardiff. Over to you. Simon, the first electoral test for the Prime Minister is looming. Back to today and the here and now, the reaction to this news from wales, theres been support from paul davis, leader of the welsh conservatives who voted for borisjohnson, of the welsh conservatives who voted for Boris Johnson, he of the welsh conservatives who voted for borisjohnson, he said he believes in the current political situation, we need charismatic, uplifting positive leadership which boris will deliver and a short while ago, just after the announcement was made, i spoke to the secretary of state for wales, alun cairns, and he felt the scale of mrjohnson s victory reflected the response on the ground. He said he thinks Boris Johnson will unite communities from within and really have a sense of purpose that is optimistic about a post brexit britain. The position of the Welsh Government towards this conservative leadership contest has a lwa ys conservative leadership contest has always really centred on brexit. They had demanded whoever took the hot seat in number ten would rule out a no deal brexit because they believe that would be catastrophic for the welsh economy in terms of jobs here and exports. We note Boris Johnson is ruling nothing out, but in his initial response which came ina in his initial response which came in a tweet from the first minister of wales, he said he wishes Boris Johnson well, he hopes he will demonstrate maturity and Strategic Thinking and face the challenges to come and he looks forward to meeting him. Im sure one of the item agendas that the first minister will wa nt to agendas that the first minister will want to discuss will be what happens to the cache that replaces eu structural funds in wales because borisjohnson did structural funds in wales because Boris Johnson did cause structural funds in wales because borisjohnson did cause some part of a row when he suggested a cardiff hustings, that london ministers should have some say over that. Thank you to all our correspondents there thats the view from around the uk. He was the former mayor of london, has served as a foreign secretary and credited with helping the leave campaign. But what else do we know about the man who will enter downing street as Prime Minister tomorrow . Our chief Political Correspondent vicki young takes a look back at borisjohnsons career. Applause. Yeah, i like it i like it hes one of the most recognisable faces in westminster, the celebrity politician known simply as boris to most. Boris a man who defies the normal rules of politics. Say Brexit Brexit from journalist to mp, mayor to foreign secretary, many predicted that the scrapes, scandals and gaffes which prevent his rise to the top. Would prevent. Are you a member of the conservative party . But today Boris Johnson fulfilled his childhood dream, to become Prime Minister. He puts people at ease. He tries to level with them. He connects with people, which is part of the magic of his appeal, but behind that is
