For the president . And a pawn in a global power struggle, how irans seizure of a british flagged tanker has affected one crew member the ships cook. Hello and welcome to bbc news. Here in the uk borisjohnson is preparing for the biggest act of his political career. On wednesday hell be invited by the queen to form a government, and then enter 10 downing street as Prime Minister, fulfilling an ambition hes admitted to holding for decades. Newly elected as conservative party leader on tuesday, he claimed in his acceptance speech that he would unite the country and take britain out of the European Union by the end of october. Heres the bbcs Political Editor laura kuenssberg. Applause. And therefore i give notice that borisjohnson is elected as the leader of the conservative and unionist parties. A brief moment of where do i go now, as the rest of the room got to its feet. A thumping majority for mrjohnson a knowingly controversial pick. There will be people around the place who will question the wisdom of your decision and there may be some people here who still wonder quite what they have done. No one party, no one person has a monopoly of wisdom, but if you look at the history of the last 200 years of this partys existence you will see that it is we conservatives who have had the best insights. Talking as a tory campaigner complete with gags, the Prime Minister with the most serious of tasks from tomorrow. At this Pivotal Moment in our history, we again have to reconcile two sets of instincts. Two noble sets of instincts. Between the deep desire for friendship and free trade and mutual support in security and defence between britain and our european partners, and the simultaneous desire, equally deep and heartfelt, for democratic Self Government in this country. Brexits not impossible, he says, it can and must be done. Well, i look at you this morning and i asked myself, do you look daunted . Do you feel daunted 7 i dont think you look remotely daunted. The people of this country are trusting in us to do it, and we know that we will do it. On the threshold of number 10, still entertaining this crowd. I know some wag who has already pointed out that deliver, unite, and defeat was not a perfect acronym for an Election Campaign since unfortunately it spells dud, but they forgot the final e, my friends e for energise and i say to all of the doubters, dude, we are going to energise the country, we are going to get brexit done. In a new spirit of can do, we are going to unite this amazing country. The campaign is over and the work begins. Thank you all very much. Applause. Hes the master here now. The new leader arriving to meet the party troops at conservative headquarters. A victory for a man whose political career has been down almost as much as up. A triumph of animal spirits over analysis, perhaps. Borisjohnsons big sell belief. You cant question mrjohnsons enthusiasm for the pursuit of ambition nor his promise to making the most of brexit cleaning up the mess he helped to create. But as he was cheered by tory mps in the commons this afternoon, they all know a sumptuous turn of phrase, a love of controversy and power, wont be enough on their own. Laura kuenssberg, bbc news, westminster. World leaders have been congratulating mrjohnson. President trump was one of the first, declaring hell be great. We have a really good man is going to be the Prime Minister of the uk now, borisjohnson. Applause. Good man. Hes tough and hes smart. They say britain trump, they call him britain trump. And people are saying thats a good thing. They like me over there. Thats what they wanted. Thats what they need. Applause. Thats what they need. Hell get it done. Boris is good, hes going to do a good job. Borisjohnson has made brexit a priority, claiming that do or die, britain will leave the European Union by the end of october. The incoming new head of the European Commission ursula von der leyen said mrjohnson faces challenging times ahead. There are many different and difficult issues to tackle together. We have challenging times ahead of us. It is very important to build up a strong and good working relation because we have the duty to deliver something which is good for people in europe and the united kingdom, so i am looking forward to working with him. Our europe editor katya adler says the messages of congratulations are coming in from european leaders, but its very uncertain how the new Prime Minister will fare with the European Union in any new moves on brexit. There were messages of congratulations from across europe today. Jean Claude Juncker said he would work as constructively as possible with borisjohnson and in these divisive times, Emmanuel Macron of france reminded the new Prime Minister that eu uk relations stretch far beyond brexit. That whatever happens with brexit, when it comes for example to iran or to russian sanctions, the eu still sees the uk as a close ally on the world stage. That said, those warm and welcoming words, which are essentially the polite diplomacy shouldnt be misconstrued as the eu taking a just because we are getting a new Prime Minister. On one hand, corresponds and is right, the eu has more flex ability over the brexit deal than it has wanted to let on until now. But he is probably wrong if he thinks the threat of a no deal brexit, and however much we know eu leaders would like to avoid it will cause a major rethink in brussels. The eus flexibility is much more constrained than that. They wont wa nt to constrained than that. They wont want to make decisions or compromises that ultimately will hurt them. So some changes to that irish backstop rnc, possible, if dubs than says yes in ireland are possible, but if it means exposing the lucrative Single Market to non regulation goods it would mean turning their backs on island. I dont see them going in that direction at all on ireland. So when exactly will mrjohnson become Prime Minister . On wednesday, after her final Prime Minister questions, theresa may will go to Buckingham Palace and tender her resignation to the queen. Soon after that, mrjohnson will travel to the palace where hell be invited to form a government. Hell then make his way to downing street to give his first speech as the new pm. Borisjohnson has served as london mayor, foreign secretary and played a leading role in the leave campaigns victory in the brexit referendum. What else do we know about the man who will enter downing street on wednesday . Our chief Political Correspondent vicki young takes a look at his career. Oh, please call me boris. Say brexit today he has fulfilled his childhood dream to become Prime Minister. I have seen in the last few months are becoming increasingly reflective of the scale of the challenges that he is about to take on andi challenges that he is about to take on and i am absolutely convinced that he is emotionally and intellectually ready for this. He knows the scale of it and hes up to it. Boris Johnsons Park to the knows the scale of it and hes up to it. Boris Johnsons Park to the top isa it. Boris Johnsons Park to the top is a well trodden one. The 20th Prime Minister to be as good at it oxford university. A career in journalism followed with a stint in brussels for the telegraph where he relished mocking the European Commission. His profile was boosted by tv appearances. Boris johnson commission. His profile was boosted by tv appearances. Borisjohnson had set his sights on a political career and where better than the safe conservative seat of henley upon terms. But even back then as Boris Johnson tried to become the conservatives candidate, the local party was divided over his talents. Some were attracted to this slightly eccentric larger than life personality, but others were concerned about whether he could be taken seriously. What you see is what you get. You get the hands going through the hair, you get the slightly dishevelled look, its appealing to a lot of people. We found that when we were campaigning with borrowers, when he was an mp, he would lead people behind him to make everything happen, he would be the person with a charisma, the person in charge. And that is the approach he took when he was elected mayor of london in 2008. Such an honour to have you here, mr mayor. 0h, honour to have you here, mr mayor. Oh, please do me boris. He was the charismatic front man, happy to perform for the cameras. And the mishaps only added to the celebrity status. Released the rings into position. Now his supporters that his leadership style is all about getting a feelgood factor. Hes good at bringing people together, actually, some people consider him to be divisive because of the things hes written and set in the past, however, he is able to go into a room and get people feeling positive and feeling like they can achieve some change. He did it in london, lets hope he can do it for the country. Good morning boris. Over the years, his private life brought u nwa nted the years, his private life brought unwanted president ial. During his only five year marriage he had several affairs, he was sacked as a conservative spokesperson for lying about one of them. Last year, his lip and his wife marina. Professional relationships have been strained, to last year his wife marina. He mistakenly told mps that a british citizen imprisoned in iran had been training journalists in the country, he suggested libya had a bright future, if it could only clear the dead bodies away. Collea g u es clear the dead bodies away. Colleagues complain he didnt focus on important details and found it ha rd to on important details and found it hard to make decisions. There is a real trust deficit, so that he hasnt done what is supposed to have done, he hasnt read his briefs, he hasnt turned up to things, he hasnt turned up to things, he hasnt put the Country First but his put himself first. But friends insist his unconventional approach could charm even the toughest of audiences. The bastian and the bad limbs. Many conservative mps are pinning their hopes on borisjohnson because they believe hes a winner, he drew adoring crowds when he led the votes are live campaign. But brexit has proven to be the most divisive of issues. I like it, its brilliant the new Prime Minister will need more than exuberance, charisma and a bit of optimism. Delicious. Young, bbc news.

Thank you for watching. Hello. Temperatures have been soaring across the uk. In fact, to record levels forjosey on tuesday and a newjuly record set in maison saint louis of 35. 7 degrees celsius. And dont be too surprised i think if we dont see some further records being broken before this hot spell is out. The peak anticipated on thursday and some spots could get up to 37 degrees celsius and that would be a new ukjuly record. To start us off on wednesday, plenty of humidity around, and some pretty widespread thunderstorms across the northern half of the uk. Potentially some big hail, gusty winds and a lot of lightning and thunder. Losing their intensity as they drift across scotland through the morning. They clear from all but the Northern Isles by the afternoon. Then we are then left with widespread sunshine. Bit more of a south westerly flow today. So that will just take the temperatures down a little towards the west of the uk but still some hotspots in the east facing highs of 32 or 33 degrees. Through the evening and overnight, not a lot of changes but youlljust noticed some business going on out here towards the western area of low pressure is trying to get closer and what that is going to do is increase the southerly flow for thursday. Thursday morning, again, a very hot affair after a very uncomfortable night. It is all to do with that wind direction though, bringing the extreme heat on a thursday. That southerly wind tapping us in to heat from the continent, where were looking at record breaking temperatures for parts of belgium, the netherlands, luxembourg and germany on thursday. That hot air surges into the uk too. This front trying to approach from the west could spark off a few showers ahead of it. But in eastern areas, as the sun beats down, we are anticipating about an 80 chance of thatjuly record being tumbled somewhere in the south east of england, probably favouring somewhere around the Greater London area or parts of kent. The Current Record stands at 36. 7 degrees celsius and that was set at heathrow on the first ofjuly in 2015. If it is all getting a bit much for you, though, there is some hope for the end of the week. The low finally starts to really bring in its implements overnight, thursday into friday. Nothing actually particularly dramatic in the way of rainfall for many areas but fresher air arriving behind the cold front for friday. Still pretty warm in london but were back down to much more average temperatures for the likes of belfast and cardiff. As for the weekend, definitely a fresherfeel for all, and the potential for some quite rain in places as well. This is bbc news.
