arsenal captain laurent koscielny is described as devastated as it confirmed the defender will be out for six months following surgery to his achilles tendon. good afternoon and welcome to the bbc news at one. president trump is preparing to announce this evening whether he'll abandon an international deal with iran reached in 2015 and seen by britain and other western allies as the best way of stopping the country from developing a nuclear weapon. mr trump has long been scathing about the agreement, and there's been a frantic round of last minute diplomacy from other countries to try to stop the president pulling the united states out of the deal. richard galpin reports. the world once again focusing on

donald trump and his decision to go out iran nuclear deal. many times he's expressed his desire to see it scrapped. yet for the past three yea rs scrapped. yet for the past three years it is believed to have curtailed iran's ability to develop nuclear weapons while giving the country respite from punishing economic sanctions. unravelling the deal now could further destabilise the middle east which is already mired in conflicts such as here in syria for iran is playing a prominent role. it's very possible that escalation in the region is going to hamper peace, help a proxy war with other regional countries and full impact saudi arabia but also possibly with the united states as well. in recent days and array of

european politicians including boris johnson have travelled to washington to try to persuade the white house not to pull out of the deal and reimpose sanctions on the iranians. how much impact they have had is not clear. but already in iran the fear of what may be announced later today has led to the local currency crashing to almost record lows against the dollar. and the price of oil globally has increased over concerns iran's oil exports could be cut if the united states reimpose sanctions. today at a meeting in tehran the iranian president said whatever happens now iran would stand on its own two feet. but he also said tehran would still keep sick constructive relations with the world if the us pulls out of the nuclear deal. richard galpin, bbc

news. the iran deal was seen as the key foreign policy achievement of the obama presidency — but it has had its critics from the moment it was signed. our diplomatic correspondent paul adams explains what the deal said, and examines the impact it's had. is the iran nuclear deal about to be killed off? it came after years of tension over iran's alleged efforts to build a bomb. iran had always said its programme was peaceful but no one believed this and for almost ten years the un imposed sanctions. the deal brought together the five permanent members of the un security council and the eu. it was called the joint comprehensive plan of action, the jcpoa. but what exactly was in it? iran agreed to do away with large parts of its nuclear programme and allow international inspectors to monitor the rest. this involved giving up large stockpiles of enriched uranium and thousands of centrifuges. as a result experts believed it would take iran much

longer to make a bomb in the future. up from 2—3 months to around a year, giving the international community much more time to respond to a crisis. in return, the international community agreed to lift sanctions. iran could recover billions of pounds of frozen assets, it could sell more oil on the international market and trade like a normal country. iran is sticking to its side of the bargain but the deal has always had its critics. israel and saudi arabia say, it isn't tough enough. israel's prime minister benjamin netanyahu in particular says iran should not be trusted. iran lied. big—time. donald trump says it's the worst deal in the world. the iran deal was one of the worst and most one—sided transactions... i've ever seen drawn by anybody... ever... ever! he's been threatening

to walk away unless what he sees as the deal‘s flaws can be fixed. what are these perceived flaws and can they be fixed? for one thing many of the deals key provisions expire after ten, 15 or even 25 years. for some, this is a problem. nor does the dealer address the ballistic missile programme or iran's singing aggression in the middle east. no one quite knows what mr trump has in mind but if he does make good on his threat the deal‘s other backers have a problem. do they try and keep it alive by themselves or pressure iran into accepting new conditions? if that happens, iran too could walk away. paul adams, bbc news. our correspondent barbara plett usher is in washington. so what's the thinking there barbara in terms of what its expected president trump will do what we are expecting is that he

will impose sanctions on iran, the middle ground of the approach he would take that is the decision, he could fix for its reimpose sanctions in phases starting with those that affect iran's oil sales and he could give wiggle room to allies to allow them to keep eyeing the oil while there are negotiations over the final outcome or he could announced the intention to reimpose sanctions and use that as a brinkmanship to see how the parties respond. with that force iran back to pre—negotiate the deal ultimately? would that mean the europeans could be pressured to be tougher on iran, what would it mean be effective? those are lots of questions to be answered but the bottom line is we are entering uncharted territory, there is no set formula for how you on fine with this deal, i rather suspect it's not

going to be a simple in or out which in some ways may be preferable to the europeans rather than having the deal limp along in limbo under co nsta nt deal limp along in limbo under constant threat. thank you. the chinese president xi jinping and the north korean leader kimjong un have met in northeast china during an unannounced visit. it's kim's second trip to china since march and comes ahead of a planned summit with donald trump. our correspondent, laura bicker, is following developments from seoul. how much of a surprise is this second trip? this is a big surprise, there is been speculation for the last few hours, is he, isn't he back in china, turns out he is. for a leader that hadn't left his country since he took power in 2011, this is a flurry of diplomacy. why? johnson has promised his people a move towards an economy, he has been focused on building his nuclear weapons and the economy, he is now saying we are nuclear state, let's

focus on trade and he needs his key trade partner. china accounts for 80-90% of trade partner. china accounts for 80—90% of north korea's trade, over the last few months china has been taking part in un sanctions. if north korea and china form an alliance and if north korea shows to the chinese president that he is prepared to get around the table with the us and prepared to discuss denuclearisation, it may well be enough for the chinese president to say let's talk about trading once again. but there are things to note in the statement that came from china, it talked about the relevant parties talking in a phased manner about eventually denuclearise in, this isn't just about eventually denuclearise in, this isn'tjust kim about eventually denuclearise in, this isn't just kim jong—un about eventually denuclearise in, this isn'tjust kimjong—un handing over his weapons, he is going to wa nt over his weapons, he is going to want something in return from the us and it may well be that us troops here on the peninsula are hard of that adam and chips. laura, thank you. —— that bargaining chip.

the foreign secretary, borisjohnson, has described one of downing street's options for post—brexit customs arrangements as "crazy". the proposed customs partnership would involve the uk collecting import tariffs on behalf of the eu. number ten says the idea is still on the table after ministers failed to agree a plan last week. 0ur political correspondent eleanor garnier reports. no holding back from the foreign secretary this morning, he is on the move, warning against one of the options for trading with the eu after brexit. is the brexit plant crazy and are you ready to resign? cabinet ministers are still struggling to answer the question of how britain should trade with the bloc once we have left. 0ne how britain should trade with the bloc once we have left. one idea thatis bloc once we have left. one idea that is thought to be the prime minister's preference would mean the uk collecting tariffs on goods coming into britain that are destined for the eu and then later sending the money on to brussels. known as the customs partnership it's been heavily criticised by tory

brexiteers including boris johnson. who's told the daily mail customs partnership is a crazy system... adding it's totally untried... i think they would be seriously certifiable if they go for the idea of the customs partnership. it really ru d e of the customs partnership. it really rude run against every thing i know about. —— it really would run against. the government believes there is a high—tech solution, one that would avoid a hard border between northern ireland and the republic at the same time allowing britain to do new trade deals. but other conservatives aren't so sure. it shouldn't be about the foreign secretary or anybody, ultimately it's about getting the right deal in the national interest, something that means we don't go backwards in northern ireland but also our manufacturers are able to conduct trade across borders without unnecessary barriers. with no

consensus so for unnecessary barriers. with no consensus so for downing street says theresa may has asked for more work to be done on both options but with such deep divisions in the conservative party over brexit this complex issue of customs won't be easily solved. and these rankings arejust among easily solved. and these rankings are just among conservatives, easily solved. and these rankings arejust among conservatives, all this still needs to be sorted with negotiators on the other side of the channel. 0ur assistant political editor norman smith is in westminster — norman, boris speaking out is not new but would this be a step too far for theresa may if the proposal is kept on the table? well, so far downing street have chosen not to rise to this extraordinary intervention by boris johnson saying the prime minister still has confidence in him but i rather suspect she was probably scrunching per copy of the daily mail this morning she read or is johnson's words because let's be clear, he has pretty much publicly

trashed what seems to be her favoured option of a customs partnership with the eu after we leave the european union, describing the idea as crazy. now, if you are prime minister you might expect an opposition politician to describe your policy is as crazy, you might expect a newspaper columnist to describe your idea is as crazy, or a panellist on have i got news for you to describe your idea is as crazy, you don't expect foreign secretary to describe your ideas as crazy! two things follow from this, one the prospect of any compromise with mr johnson on the issue seems a no—hoper, there is also a question over whether any compromise can be reached with any of the key brexiteers who seem to be join a red line on the issue. the other big question is whether or isjohnson can remain in government, given that he views the option which the prime ministers seems to favour as crazy. as for the prime minister, she seems determined to hunker down, keep making the argument for the customs

partnership, trying to win over individual ministers to get a majority and to face down boris johnson and then, it's up to boris johnson and then, it's up to boris johnson to decide what he's going to do. norman, thank you. rail companies are to hold a public consultation on ticketing, to try to make the system fairer, and easier to use. the industry has admitted that people are not always offered the cheapest fare available. the consultation will lead to a series of proposals for the government to consider. passenger groups say reform is overdue, as our correspondent leigh milner reports. it's fair to say for most of us rail fares are either confusing or very expensive and not for the first time since privatisation rail companies across the country have launched a public consultation to make that process much simpler, easier and hopefully much cheaper. the regulation that was designed in the 1990s, that still drives the structure of our terrace system and since then we've had massive changes

in the way we work, travel, we've had much more flexible lives and we wa nt flexible had much more flexible lives and we want flexible ticketing. the industry admits passengers are not a lwa ys industry admits passengers are not always currently offered the cheapest available due to long—standing anomalies such as the ticketing, that means it can be cheaper for passengers to buy several tickets for a single journey rather than one. for example if you we re rather than one. for example if you were to buy an advance ticket from london kings cross to sheffield today but the 7th ofjuly leaving at 7am it would cost you £32. but if you bought two separate single tickets from london kings cross to doncaster then sheffield it would cost you £18. a saving of 56%. and you'd even get their ten minutes earlier! the rail delivery group says a reformed ticketing system could include integrated tickets which also include other modes of transport such as buses and trams but what's more interesting, they are focusing on sophisticated technology which automatically selects the lowest bare. but the

rail delivery group which represents private train operators and government owned network rail says it doesn't have all the answers which is why they want to hear from passengers. it's converted it. yes, it is, it's not clear, easy to pick the fear that you want, that suits you best. i'm very confused as to what to pick, if they are simply fired, maybe journey byjourney, and it is made easier to pick her you are going. if you can put it into one side, when you go on to other sites you have followed different sites you have followed different sites but onto one side so it is manageable and easier, you are saving time as well. the consultation will be launched next month running until september but when will we start to see changes? this will produce options on the table by the end of the year, they'll be put in front of government hopefully in the next 12-18 government hopefully in the next 12—18 months we will start to see change because it's got to happen. passengers are being reminded by the end of the reform is to make here is

cheaper and easier to access it doesn't necessarily mean average fa res doesn't necessarily mean average fares will change at all. it is 17 minutes past one. our top story this lunchtime... all eyes on the united states as president trump prepares to announce whether he'll abandon a nuclear deal with iran. and coming up, the spider hoping to help scientists in manchester make a huge leap in robotics. and coming up on bbc news... just 12 months ago we thought his career was over, but last night mark williams claimed his third world championship title, becoming the oldest winner of the tournament in 30 years. whether it's the struggle to get on the property ladder, or the cost of university education, the financial pressures facing young people continue to rise — which means the generational wealth gap is widening. now a report has suggested 25—year—olds should get a £10,000 payment from the state, and some pensioners should be taxed more.

the resolution foundation says the contract between young and old has broken down. here's our economics correspondent andy verity. a family gathering in cannock, staffordshire. 0n the left, stephanie garden was born into the post—war baby boom generation that enjoyed higher incomes and more wealth than their parents. her daughter karen, who's a8, hoped for the same but her grandson dan, born in the 1990s, has been dealt a far weaker hand. dan's age group earn no more than the same age group 15 years ago. they are half as likely to own a home at 30 and four times as likely to rent privately. i'd love to move out, get my own place, but the reality is just... you're not going to now until your, maybe, late 20s if you're lucky. so... it's just the way it is at the minute. while many pensioners are poor, on average, those drawing the state pension have higher incomes than they have ever had. after housing costs, they are higher than for people of working age. yet, if they work, pensioners pay no national insurance.

there are inevitable pressures for public spending to go up on health care and social care. and it is reasonable to expect the baby boomers, who have a very substantial part of the nation's wealth, to make that contribution towards meeting those costs, especially as it will be for services from which they themselves directly benefit. among the commission's recommendations are 2.3 billion more for the nhs, paid for by national insurance on pensioners‘ earnings and all 25—year—olds will get a £10,000 citizens‘ inheritance, which could be paid for by scrapping inheritance tax and instead taxing large cash gifts. i don't think the young ones today have got it as easy as what some people think. i think it's quite difficult for them. if the reforms were adopted, it would mean that pensioners that work pay more than they do now. the money that needs to go into health and social care is much greater than you would raise by changing this particular policy, and people of all ages need to pay

for it, because people of all ages use health and social care services. thomas, who was 1a at the time, urging him to tell police that he was the one who pulled the trigger. the trial is continuing of an army sergeant accused of trying to kill his wife by tampering with her parachute. emile cilliers denies attempted murder and criminal damage. 0ur correspondent duncan kennedy is following the case at winchester crown court. duncan?

this volcano has been erupting constantly for 30 years, but not like this. nearly 2000 people have been evacuated from the area as the lava coursed through the forest, flowing onto the roads and buildings. at the crater, geologists have been using time—lapse footage to keep watch. they expect another explosion to come, but no one knows where the next fissure might appear. there are concerns about the gas stored in this geothermal plant close to one lava flow. and worries too about the sulphur dioxide in the air, which can be deadly. experts are monitoring the volcano, but predicting it is next to impossible. it could continue for months, with little to do but watch in awe as fire and lava edge ever closer. caroline davies, bbc news. mark williams has claimed his third world snooker title — 15 years after his last. the welshman beatjohn higgins from scotland in a dramatic

final in sheffield. 0ur sports correspondent andy swiss reports. ina in a sport note the dapper clothing, this was a night her naked ambition. as mark williams celebrated his title, his winning streak was not finished. i wonder whether you will make good your promise to bare all the media conference afterwards? i have to do it, i have to do it. just moments later, there he was to face the world's media, with only a bath towel to protect his modesty. williams never dreamt he would have to carry out his promise, he watch the tournament last year on television in his caravan. it is fairto television in his caravan. it is fair to say this triumph was barely believable. 12 months ago i am thinking about chucking it, here i am doing an interview having just won the 2018

world championships. bleep. an unbelievable 12 months. briefly it seemed he might be able to keep his cloves on. that pink would have given him the title, but instead john higgins conjured a remarkable fightback. unbelievable! one of the tightest finals of recent times, but eventually, thrillingly, it was williams‘ night. he is the oldest champion since 1978 and hopes to do it again next year, but perhaps with one crucial difference. i will keep my mouth shut next year, i will keep my mouth shut next year, i will not say anything stupid and end up like this. i mean, to be honest, if i won this next year i would do it again, i would cartwheel naked! it is something he probably never considered when he won his first world title in 2000, but if 18 years seems a long time, last night‘s

press c0 nfe re nce seems a long time, last night‘s press conference probably seemed even longer. can ivri breathe out now?! andy swiss, bbc news. i am trying to do a segway, but i‘m not going to! now i don‘t usually mind spiders — but if you‘re not keen i would look away now because this might test you. scientists in manchester say they‘ve made a huge leap in robotics, after studying this spider — the regaljumping spider — this one nicknamed kim. kim can leap six times her body length from a standing start. experts say their studies of her could help design a new generation of robots. 0ur science reporter helen briggs explains. ready, steady, go! ajumping spider shows off the skills she needs to hunt her prey. nicknamed kim, she canjump six times hunt her prey. nicknamed kim, she can jump six times her body length with remarkable precision. unlike other spiders, she was trained to lea p other spiders, she was trained to leap in the lab. and she was giving

up leap in the lab. and she was giving up her secrets in the name of science. the lead researcher on the project was amazed by the spider‘s agility. the moment when we succeeded to train kim tojump between the platforms was amazing. we started collecting the data very quickly and they were saying how small she is, to the limit even sometimes i was looking to her in the eyes, she is very small, she will get shy and gave me her back when i looked at him in the eyes. simply fantastic. researchers are looking at a new generation of jumping robots which could be used in the future to catch pests, just like spiders do. consolation for arachnophobia, spiders have many practical uses. time for a look at the weather. here‘s darren bett.
