this is bbc news, i'm carole walker. the headlines at 11:00pm: president trump announces the united states' withdrawal from the iran nuclear deal, and makes moves to reinstate nuclear sanctions. i will sign a presidential memorandum to begin reinstating us nuclear sanctions on the iranian regime. we will be instituting the highest level of economic sanctions. borisjohnson still has downing street's support, despite calling the prime minister's choice for customs controls after brexit crazy. rail companies begin a public consultation to make tickets fairer and easier to use, following criticism of the current fare structure. and on newsnight, donald trump has pulled out of the iran nuclear deal, making his biggest foreign policy

the president had been repeatedly urged by allies, including britain, not ta pull gut: nick bryant reports. with a flourish of his presidential pen, donald trump has inked into history one of the most muscular pledges from his "america

it didn't bring calm, it didn't bring peace and it never will. therefore, i am announcing today that the united states will withdraw from the iran nuclear deal. in one of his toughest speeches yet, he said he would reimpose the highest level of economic sanctions against tehran. america will not be held hostage to nuclear blackmail. we will not allow american cities to be threatened with destruction, and we will not allow a regime that chants "death to america" to gain access to the most deadly weapons on earth. today's action sends a critical message. the united states no longer

makes empty threats. when i make promises, i keep them. the nuclear deal was struck in 2015 between iran and six world powers, including the us, uk and russia. iran agreed to limit its controversial nuclear energy programme, which international powers feared could lead to the development of a nuclear weapon. in return, stringent economic sanctions were lifted, enabling iran to sell more oil to other countries and trade more efficiently. iran's president, hassan rouhani, deliberate an almost instantaneous response, saying his country was preparing to restart uranium enrichment, key for making both nuclear energy and weapons. translation: i have ordered the atomic energy organisation of iran to be ready to start the enrichment of uranium at industrial levels. we will wait a few weeks and speak with our allies. all depends on our national interests.

european architects of the deal present at its creation three years ago tonight gave a grim faced response. the european union is determined to act in accordance with security interests, and to protect its economic investments. the nuclear deal with iran is the culmination of 12 years of diplomacy. it belongs to the entire international community. it has been working, and it is delivering on its goal, which is guaranteeing that iran doesn't develop nuclear weapons. but praise from america's closest middle east ally. israel thanks president trump for his courageous leadership, his commitment to confront the terrorist regime in tehran, and his commitment to ensure that iran never gets nuclear weapons, not today, not in a decade, not ever. from barack obama tonight, a rare public rebuke

of his successor. he called the decision misguided, and a serious mistake. this will make america much safer. donald trump is unapologetic. for him it is promise made, promise kept. president trump also announced that the us secretary of state, mike pompeo, is on his way to north korea. it all comes as north korean leader kim jong—un made another surprise visit to china, where he held talks with president xi. china is keen to maintain its influence, as our correspondent john sudworth reports from dandong, on the border between north korean and china. as the two men took their amiable stroll by the sea, it was hard to believe that one was, just a few months ago, an international pariah with whom even china was said to be losing patience. now, he is the man of the moment. the chinese president signalled his approval. dialogue with america,

he said, can bring peace. in the city of dandong, up the coast from where the leaders are meeting, investors clutching property portfolios are hoping that with peace comes something else — prosperity. translation: property prices rose a lot this year. they doubled. they've gone up because of kim jong—un. only a narrow stretch of water separates the city from north korea, and the contrast between the two banks could not be more stark. this bridge ends in a field, because north korea has not yet built the connecting road. it is a pristine, gleaming highway, and it is proof of the huge economic potential if the impoverished country at the other end of it ever were to open up. but this unfinished bridge is proof

of something else, too. that time and again, just as the world has sensed change, north korea has chosen isolation over reform. chinese homes along the border have quite literally been shaken by the nuclear tests. there are plenty here who doubt whether north korea, having tried so hard to get its weapons, will ever give them up. but one chinese couple, in their new home overlooking the new bridge, insist that this time the difference might be kim jong—un himself. translation: he is a young leader. he has been been abroad. i think he wants to develop north korea, and improve its economy, so i think there is hope. but chinese reports suggest mr kim won't accept unilateral disarmament. beyond the goodwill, it is a potential stumbling block,

and a reminder that it is only a few short steps back to the brink. john sudworth, bbc news, dandong. in the house of lords, the government has suffered yet another defeat, the 13th so far, over its brexit plans. a majority of 27 peers backed retaining key aspects of the single market through continued participation in the european economic area, in defiance of both the conservative and labour frontbenches. meanwhile the foreign secretary, boris johnson, dismissed one of theresa may's proposals for handling customs duties after brexit as crazy. his remarks were directed at the idea of a so—called customs partnership, where the uk would be responsible for collecting some duties on behalf of the the eu. our deputy political editor john pienaar has more details. is that boris johnson? what did he call the brexit plan —

the one theresa may supports? crazy? surely not. if the brexit plan is that crazy, are you ready to resign? how are you? how are you, he said. fine, can't say the same for him or the cabinet. sir, is the government's customs partnership a crazy idea? word is the brexit secretary is not keen on the pm's choice of plan either — thinks it is too complex. the buck stops here. the prime minister has to get a plan, and her divided cabinet, together. so what are the customs options? the brexiteers' favourite is a sharp break, and use new technology to avoid stops at the border. and mrs may's — a customs partnership. britain collects customs duties, passes on some cash to the eu, and refunds traders when there is a cheaper british trade deal. so no blockages, and no hard border with ireland. in today's daily mail, mrs may's favourite paper, borisjohnson called that idea crazy, tied to the eu. could you ever support a plan you call crazy? so now the prime minister

must win the argument, somehow convince colleagues like the home secretary she has just promoted, or maybe her ally the defence secretary, if she can, or repackage the plan. no—one is sure how to pull it off, ministers least of all. in a word, do you think there can be any kind of compromise on customs? she laughs. you don't sound too confident. there will be a fight here, whatever is agreed. brexiteer mps seem immovable. i think they would be seriously certifiable if they go for the idea of the customs partnership. it really would run against everything i know about government. mps doubtful about brexit want to steer a course close to the eu, for the sake of british business. ultimately, it's about getting the right deal in the national interest, something that means that we don't go backwards in northern ireland, but also that our manufacturers are able to conduct trade across borders without unnecessary barriers. tonight, there are signs borisjohnson may rather stay and fight for his vision of trade

after brexit inside the cabinet. but brexiteers won't like any customs compromise. there is still a chance that parliament may demand britain stays inside the eu customs system, and brussels mayjust throw out the whole idea. brexit was always likely to lead to trouble in the cabinet, in parliament, and in brussels. theresa may surely can't have imagined it would be quite this tough. labour has sacked debbie abrahams as shadow work and pensions secretary, after investigating allegations of workplace bullying. ms abrahams, the mp for oldham east and saddleworth, rejected the allegations and said the investigation had not been fair or independent. rail companies are launching a consultation to try to make buying a train ticket simpler and fairer. the rail delivery group, which represents railfirms, says there are some 55 million different fare combinations in the current system, and it admits that customers aren't always offered the cheapest fare available. our transport correspondent victoria fritz reports. crowded, expensive,

and the busiest in europe, and with 55 million different types of fares on britain's railways, it is little wonder that two thirds of passengers aren't even sure if they've bought the right ticket. i'm very confused as to what to pick. so if it's simplified, maybe journey byjourney, and it's made easier tojust pick where you're going. i do think that there is a need for it to be slightly better regulated, because otherwise you could end up making the wrong choice, and ending up paying more than you need to. there's a lot of disparity between what the prices are, when they come out, and stuff like that. so i think, actually, this consultation is a really positive step. for the first time, the numbers of people choosing to travel by rail in some parts of the country is falling. train companies admit that change is needed to restore trust in the system.

well, we know that customers don't always feel that they're getting the right ticket, or they're not confident of that. we want to improve that trust so they have confidence, and we can drive further improvements through radical reform of fare regulation, and improve things for customers and the economy. the mid—‘90s brought privatisation, and with it, over 400 pages of new regulations for the railways. but those rules no longer apply in a world of flexible working and travel. the way we are buying our fares is changing, too. we're far less likely to go in there, the ticket office, than we are to go on here, online. and some passengers are managing to pay less for their journey by splitting up their fare into a series of single tickets. for example, if you were to buy a ticket from london kings cross to sheffield today, for 7 july, leaving at 7:00am

in the morning, it would cost you £32. but, if you bought two separate tickets, from london kings cross to doncaster then sheffield, it will cost you £18. that is a saving of 56%, and you would even get there ten minutes early. although train companies have pledged that average fares will not rise as a result of reform, some journeys could still become more expensive. where to set fares is ultimately a decision for the government. what is fundamental is that the government commits now to implementing the findings of this review and this consultation. a simpler system will be welcomed by all rail users, but closing cost—saving loopholes like split ticketing may be a far harder sell to passengers. victoria fritz, bbc news. now it is time for newsnight. the iran deal is defective at its core. if we do nothing we know exactly what will happen. donald trump ends the iran nuclear deal and reimposes tough economic sanctions, ignoring the pleas of germany, france and the uk. so what happens now?

the europeans vow to defend the deal, but we're in uncharted waters now, while tensions in the middle east run high. we'll hearfrom, among others, former deputy assistant to the president, sebastian gorka and journalist nazenin ansari. also tonight: borisjohnson is on manoevres again, deriding theresa may's proposals for a customs partnership with the eu as crazy, but cabinet arithmetic suggests she can't lay a glove on him. the longest—serving mp, ken clark, has his own boxing gloves. and ronan farrow helped bring down weinstein. now he's co—authored an expose on the new york attorney general. how hard is it to pursuade women to speak out? we are living in a very different climate right now.
