welcome to bbc news. broadcasting to viewers in north america and around the globe. my name is lewis vaughanjones. our top stories: president trump remains hopeful that the summit with kim jong—un will go ahead, after north korea threatens to cancel the talks. the home of the ousted malaysian prime minister is raided by investigators, as the man he once jailed hails a "new dawn". enough of intimidation! no more! we have entered a new era. with shortages of food and medicine, thousands of venezuelans cross the border to brazil every day to seek medical care. prince george and princess charlotte will lead the pageboys and bridesmaids at the royal wedding, but it's still not clear whether meghan‘s father will be there. president trump has hinted

that the much—anticipated summit between him and the north korean leader, kimjong—un might not go ahead next month. he was speaking after the authorities in pyongyang threatened to cancel the talks, if the us continued to push for an end to its nuclear weapons programme. our north america editor, jon sopel has more details. it is an annual event, and each year it upsets the north — a military training manoeuvre involving 100 warplanes from the us and south korea. and last night, pyongyang engaged in their own live—fire exercise, with a threat to shoot down next month's planned summit. but if this was provocation, donald trump was doing his best not to react. his comments in the oval office were conspicuously muted. we haven't seen anything, we haven't heard anything. we will see what happens. though, in the hubbub, he was asked

whether he was still insisting on north korea getting rid of its nuclear programme. yes, he says, but this is the thorniest issue. denuclearisation means one thing to the us, and something completely different to the north. the us national security adviser has said disarmament must be complete, verifiable and irreversible. he says it should be what colonel gaddafi did in libya. i think we're looking at the libya model of 2003—2004. we're also looking at what north korea itself has committed to previously. but look what happened to colonel gaddafi. without his weapons he had lost his insurance policy, and he was ousted from power. north korea isn't going to go down that route. and what was noticeable this morning was that the white house press secretary seemed to put quite

a distance between the president and mr bolton's libya model. i'm not aware that that's a model we're using, but i would... bolton said that over the weekend. i haven't seen that that's a specific thing. i know that comment was made, but there is not a cookie—cutter model on how this works. this is the president trump model. he's going to run this as he sees fit. donald trump has invested heavily in making the summit a success, and there is no doubt there is determination in the white house that it should go ahead. but not at any price, and there are some intractable issues that could still derail it. so will we see an even more improbable handshake moment? in seoul, on a film set, people queue to replicate it. president trump wants this to be his framed moment in history, but we're not there yet. we'll have more on north korea later in the programme. the stay in the united states now, so. “— the stay in the united states now, so. —— let's stay in the united

states now, those. ——— though. president trump has filed a lengthy document with regulators in washington, admitting that he'd reimbursed his personal lawyer more than $100,000. the money is understood to have been used to buy the silence of the porn star, stormy daniels. let's go live to washington and our correspondent chris buckler. so chris, we have it in black and white. a payment was made, what conclusions can we draw from that? this is an ethics disclosure, we can exactly how much was paid or what the purpose exactly was for. but what we can say is that between $100,000 and $250,000 was paid by donald trump to michael cohen. it is listed as expenses and we know what the expense was. it was $130,000 that was paid to the pornography actress stormy daniels before the pretty 16 presidential election, essentially to stop talking about her alleged affair with donald trump, an affairthat

her alleged affair with donald trump, an affair that he continues to deny. 0f trump, an affair that he continues to deny. of course, there will be many russians about his payment and it wasn't included in a previous financial disclosure and the government agency that is responsible for taking in these payments, taking the details, has made it very clear that it should have been, as far as it is concerned. that is denied by the white house but it again raises questions about whether or not donald trump tried to at some stage hide this payment. it was only a matter of a month ago that he was denying exactly knowing any details about this cash or indeed where michael cohen got the cash to pay stormy daniels. that is the key point, the question of whether this payment was an illegal campaign payment. it comes down to this question about exactly why was the payment made? now, they are continuing to deny, certainly donald trump's lawyers are continuing to deny that it was anything to do with

campaign finances. however it is a question that is continuing to be asked because there are many who believe that potentially this payment and stopping stormy daniels from speaking may have influenced the presidential election and if it was a the presidential election and if it wasa campaign the presidential election and if it was a campaign contribution, it would have broken campaign finance rules. therefore, it is something thatis rules. therefore, it is something that is being investigated. i mentioned the us office of government ethics, which has released this information along with the declarations, it has also released a letter which it has said to rod rosenstein, the deputy attorney general and the man who is overseeing that special counsel investigation into allegations that russia interfered with the us presidential election. in that letter, he specifically says that this declaration should have been made earlier and he is sending both this financial declaration and the last one to rod rosenstein and in his words he says you may find the disclosure relevant to any enquiry you may be pursuing. it gives the

indication that the last questions have not been asked about this payment. thanks for that. very briefly on the russia investigation, the alleged collusion, there were another bank of documents released about this put the 16 trump tower meeting. what you think the significance is here? this is the senatejudicial significance is here? this is the senate judicial committee releasing this, they have released 2500 pages of documents. they detail a lot of interviews and evident that was taken, specifically they look particularly at donald trumpjunior and some things that he said. it raises more questions. for example it talks about an e—mail in which he says, i love it when these suggestions, that in these trump tower meeting is that took place to inhibit and tower meeting is that took place to inhibitand a tower meeting is that took place to inhibit and a number of individuals connected to russia, that they may get some dirt about hillary clinton but the biggest questions go on to be just exactly what he said to his

father, the president, shortly after that. there are questions about a block number, it was known that he took a phone call and had phone calls from a blocked number, the question is was that blocked number from his father, who has been known to use a block number on occasions. there are also questions about exactly the misleading statements that were given shortly afterwards, questions about whether or not donald trump potentially gave some guidance as to what those statements should be. thank you very much. police in the malaysian capital kula lumpur have been seen raiding the home of the former prime minister najib razek. man who until a week ago was the prime minister. mr razek‘s lawyer said the search was in relation to a money laundering probe and that the police did not find anything incriminating. he was put under a travel ban at the weekend. 0ur correspondentjonathan head is in kuala lumpur and spoke to mr ibrahim after his release.

0ne one of the things he was keen to stress once he was out, was that he was very confident in the job that he was doing, that he is happy to let him do thatjob. they have and agreement, but a need was one that was repeated. he will hand over power, to anwar ibrahim within two yea rs of. power, to anwar ibrahim within two years of. anwar ibrahim is looking tired and certainly older before he went into prison. he was saying, let him govern, i have no desire to get into politics, i want to travel. he also stressed that as far as things are going, he is comfortable with the processes that have been undertaken even in these last few days while he has still been technically incarcerated.

importantly, cabinet technically incarcerated. importa ntly, cabinet positions technically incarcerated. importantly, cabinet positions are starting to be confirmed. he raised no objection to the secretary general of the democratic action party, the mainly chinese party, taking the finance minister, a powerfuljob taking the finance minister, a powerful job that was taking the finance minister, a powerfuljob that was cruise controlled by najib razek, that go into a big chinese parties. they at one third of the coalition in terms of seats, an important symbol that cabinet positions will be given fairly. as far as the message we got from anwar ibrahim was that he was very comfortable with the way that ends are and was not in a great rush. let's take a look at some of the other stories making the news. more than 300 women who were sexually abused by larry nassar are to share $500 million in compensation. many of the women gave testimony against the former us gymnastics team doctor, which resulted in him being jailed for life. european union leaders have agreed to try to keep the iran nuclear deal alive and maintain their economic cooperation with teheran. meeting in bulgaria, the 28 also agreed a plan for dealing with trade tariffs that

back home in venezuela she rarely ate more than one meal a day. and with a packet of nappies costing four months' wages, she had little choice but to leave. "there's nothing like my country, i really miss it," she tells me, but admits with the prices in venezuela decent medical help was hard to come by. so there's 64 beds in this hospital, and they say that every day they are full. it's the only maternity hospital in the state. later i found karina and her friends waiting on the street, unsure where to go. eight months pregnant, karina tells me she had to sell the baby milk she'd brought with her from venezuela to pay for her transport here. translation: in venezuela you have to buy everything for the birth, and it is all so expensive. i also have two brothers who are dying because they can't get the medicines they need. my mum didn't want me to come here in my condition, but i can't stand by and watch my

brothers the way they are. i have to try and help them. i ask how she'll do that with a new baby. translation: here i thinki can help more than back home. you can get more here. if you sell something here, it's worth something. there, you can sell a thousand things and it's not worth anything. back at the hospital and demand for health services in this city has soared more than 3000% in the last couple of years. doctors say it's reached crisis point. translation: we're running out of supplies, basic medicine and beds. we are seeing cases of anaemia in pregnant women and urinary infections, because there is no medicine to treat them in venezuela, and people there aren't vaccinated. we're trying to fix all these problems, and i think this situation is going to get worse. but each new day brings new people, packing their whole life into a couple of suitcases. at this un camp, families are given priority, but there's no room for eight months pregnant karina,

who we met on the street. little max, though, is heading home to meet his family. his big sister is excited to see the new addition. "home sweet home," says his mum. but she and her husband richard tell me they are worried about the mosquitoes and the heat in these tents. the family arrived in brazil with nothing. they still have very little. not even any clothes for baby max. but with a worsening crisis in venezuela, returning is not an option. katy watson, bbc news, in boa vista. stay with us on bbc news. still to come: could disrupting our body clock lead to depression and other mental illnesses? the pope was shot, the pope will live — that's the essence of the appalling news from rome this afternoon that, as an italian television commentator

the latest headlines. president trump remains hopeful that the summit with kim jong—un will go ahead after north korea threatened to cancel the talks. let's stay with that story now. i'm joined by stephen costello, political advisor and writer on korea. he runs the policy ngo, asiaeast.org. thank you very much have been with us. thank you very much have been with us. this is a critical moment in the lead up to this summit due on the 12th of june lead up to this summit due on the 12th ofjune in singapore. what do you think the calculation here is by north korea? you think the calculation here is by north korea ? why you think the calculation here is by north korea? why are they threatening to pull out now? happy to be with you. i think now they have,in to be with you. i think now they have, in their view, to be with you. i think now they have, in theirview, offered to be with you. i think now they have, in their view, offered several confidence building measures since the winter olympics as these would include the three captured

americans, the summit with south korea, destroying part of their nuclear test site and so on. in return, the us is not really offered any confidence building measures and has raised the bar so from their point of view, it is pretty easy to imagine they would think that they are being played here. has this been are being played here. has this been a misjudgement from washington in obviously not offering a great deal of concessions but also the time in which they have gone about speaking about the summit? that's exactly right. this is a matter of tone and preparation. this is diplomacy 101. this is what you do. the trump folks are proving themselves to be amateurs at diplomacy. they have a great opportunity here and perhaps this is part of their learning curve. do you think the summit will go ahead now? there will always be

posturing and complications on the way to any agreement? can you see that going ahead? i am cautiously optimistic. there is quite a bit of investment on both sides and there really is an unusual moment you. all three of these leaders, kim jong—un, moonjae—in of south korea and president trump, are very lucky to be here and have the other two leaders to work with and this is a golden opportunity after more than a decade of frozen diplomacy. the big sticking point will of course be the issue of nuclear weapons. both sides seem issue of nuclear weapons. both sides seem to have different definitions of what denuclearisation means. but i think that's a problem. north korea even in the 1990s indicated that in exchange for security guarantees and access to economic development, they were willing to forego their nuclear programme. despite all our done, that remains the case today. the real question is

not them, the real question is america. the americans shot down a working agreement when the bush administration came in and in that sense, they are largely responsible for the current korea nuclear programme. the question is whether this trump administration can go back and be an honest negotiating partner and deliver those security and economic assurances that the north needs. we have to leave it there, thank you very much. experts have found more evidence of the harm caused by disrupting our body clocks. they're linking it to depression and bipolar disorder among other things as our science correspondent, james gallagher reports. inside every one of us is a biological clock keeping time. it drives huge changes in the way our body works. it is why you want to sleep at night and be active during the day. moods, strength, hormone levels, body temperature, metabolism and even the risk of a heart attack all fluctuate in a daily rhythm.

but we are getting very good at disrupting our body clocks. many of us are guilty of being up late at night checking our phones? thers's always something else to tweet, an article to read, another message to send. we know that messing with our body clocks is bad for our health. ask someone how they feel after a night shift or when they are jet lagged. but now there are concerns it could also be bad for our mental health. the study looked at 91,000 people, it showed that those with disrupted body clocks were more likely to have depression and bipolar disorder, and they were more lonely and less happy. i think the big concern is these devices that people use during the night time have blue light exposure which can affect your sleep rhythm. that needs more research but i think people should be vigilant and i think a good general piece of advice would be for people to turn off their mobile phones

in the evening and not look at them until the morning. but for many of us it seems that finding time to get enough sleep is a challenge. stressed and just can't sleep early. i think your body becomes acclimatised, like having a child for the first time, you get no sleep and you get used to having no sleep. i stay up too late, i watch box sets, and can't stop watching the next episode. this study on our bodies' time piece is not perfect, it cannot say for certain that disrupting our natural sleeping pattern is damaging our mental health. but the findings do add to a growing recognition of the importance of the body clock on both our health and well—being. james gallagher, bbc news. princess charlotte and prince george will be among the bridesmaids and page boys at prince harry's wedding to meghan markle on saturday.

however it's still not clear who will walk the bride down the aisle, following reports that meghan's father — thomas — is being treated in hospital. our royal correspondent nicholas witchell has the latest. on her way to her daughter's wedding — meghan markle's mother doria ragland left her home in california for the flight to london. good luck with the wedding! conspicuously not travelling was markle's father, thomas, who, according to reports, is in hospital in mexico — possibly undergoing surgery, probably not attending the wedding. though kensington palace has still said nothing officially. leading the page boys and bridesmaids on saturday will be prince george and princess charlotte, who played the roles at pippa middleton's wedding last year. harry and meghan will have ten young attendants — six bridesmaids and four page boys — ranging in age from two to seven. and while the leading players prepare, so too does the supporting cast. the harmlessly fixated, who attend all major royal events, have already bagged their places just outside windsor castle,

to the fascination of foreign broadcasters. is this level of interest representative of the country as a whole? well, of course it's not. indeed, according to some polls, among a good many people there is, well, polite indifference to it all. but not here in windsor, a town whose identity is aligned with royalty, whose rooftops have been commandeered by international broadcasters, and from where this saturday this royal wedding, with its international twist, will be broadcast to audiences around the world. nicholas witchell, bbc news, windsor. the national air and space museum in washington dc has been open for more than 70 years and is one of the nation's most popular attractions. now, for the first time, its director is a woman. ellen stofan is a former nasa scientist who spent her career studying planets. jane o'brien went to meet her. ellen, thank you for having us here.

after 25 years in nasa, what made you decide to become the director of this museum? you know, here at the smithsonian's national air and space museum, we actually have the largest collection of aviation and space artefacts in the world. what better place to try to get the next generation of explorers interested in science, technology, engineering, and math. you're the first woman to become the director of this museum. why is it that women are still so underrepresented in the space industry? you know, it's really a pipeline problem. so, you really have to attack all parts of the pipeline. issues of the pipeline, from girls at age 11 to 13 where they get discouraged and disinterested in science, to when they go to school where they're not encouraged, they're even sometimes harassed, to say how do we attack this problem at every level to make sure women are made to feel welcome? you've always focused on mars. what's so special about mars? i think mars is inspiring.

as a scientist, though, i'm really keen to get humans to mars because we think that, at about the same time life evolved here on earth, life also evolved on mars, but probably after 500 million years or so, the conditions changed, so life either migrated underground on mars or went extinct. so it's going to be hard to find. so that means i think you need people on the surface breaking open rocks and doing what scientists do to notjust find evidence of past life on mars but to try and understand it. what are the implications of life that evolved on another world for life here on earth? don't forget you can get in touch with me and some of the team on twitter. i'm @lvaughanjones. the weather for the rest of the week

and the weekend really is looking very promising. as far as the short term is concerned, really chilly this morning. we've had clear skies, so the temperatures have dipped away and in fact in some areas to barely above freezing. there's been quite a big gap in the cloud across the uk. you can see scotland, northern ireland and northern england so here, the lowest temperatures. you can see those cool colours here from scotland through the lake districtjust about into wales and northern ireland. in the south, slightly less cold. around 8—10 degrees. newcastle, first thing in the morning, possibly around two degrees above freezing but lots of sunshine on offer and it will not change through the morning of the afternoon apart from a bit of fair weather cloud building up. that's pretty much it. the temperatures not spectacularly high because it would have been

at chilly morning. around 18 in london, 13 in newcastle, maybe 15 degrees in belfast and thursday evening is looking absolutely fine across the uk. a beautiful end to the day is forecast. let's look at friday's weather forecast. lots of fine weather around but the weather will go downhill a little bit, at least for a time across western scotland, possibly some spots of rain as well but for the bulk of the country on friday, it's looking fine. maybe 19 in london, 16 in newcastle. then the important weather forecast for the weekend, high pressure anchors itself across the uk. the weather fronts are not too far away, just to the west of our neighbourhood but they will stay, can't move in any closer, because of that area of high pressure keeping the fronts at bay, the winds will be coming in from the south, dragging in warmerair, and the weather looks absolutely perfect in windsor on saturday, starting at a fresh 9 or 10 degrees and warming up to the low 20s by the time we get to the afternoon. and it promises to be a fine day across the whole of the country on saturday, light winds as well, lots of sunshine around, maybe just a bit of fair

weather cloud again, and 20 degrees in cardiff, 20 there in liverpool. eastern scotland also getting temperatures in the high teens as well. now, the weather does change a little bit in the north—west on sunday. a weather front moves in so there is some rain in the forecast for belfast, for glasgow, maybe getting into edinburgh as well. but for england and wales, the weather should hold and, again, another fine day on the way on sunday. so many parts of england and wales having a dry weekend all the way through. how about early next week? we'll start to draw in warmth once again from europe and the temperatures will keep on climbing. this is bbc news. the headlines: president trump has said it's not clear if his planned summit with the north korean leader kim jong un will still go ahead, but he's still hopeful. pyongyang has threatened to cancel the talks if washington continues to press for its unilateral nuclear disarmament. police in malaysia have searched the home of the former
