but the strategies of the two nations are farfrom but the strategies of the two nations are far from clear. the but the strategies of the two nations are farfrom clear. the us wa nts nations are farfrom clear. the us wants north korea to give up its nuclear weapons, but there's been no public indication that denuclearise asian is on the agenda with kim jong—un. this is the closest we've been to any senior figure suggesting it could be. he has indicated to me personally that he's prepared to denuclearise, that he the current model doesn't work, that he's prepared to denuclearise and two, that he understands we can't do it the way we've done it before, this has to be big and bold. but what does big and bold mean and do the us and north korea agreed on what a definition of denuclearise eight and

pressie yes. can you describe that a bit? no. earlier it was all smiles as donald trump met with japanese prime minister shinzo abe for a last—minute head to head on strategy. the president was upbeat. i think it's going to be a very fruitful meeting, i think it's going to be an exciting meeting. i think we're going to get to know a lot of people that our country never got to know. a getting to know you session rather than a high—sta kes know. a getting to know you session rather than a high—stakes meeting. perhaps playing down expectations they could be soon about to sign a deal. mr trump dismissed any suggestions he isn't prepared for whatever the talks might have in store. i don't thinki have whatever the talks might have in store. i don't think i have to prepare very much, it's about attitude, it's about willingness to get things done but i think i've been preparing for this summit for a long time. ladies and gentlemen, the president of the united states and the prime minister of japan. president of the united states and the prime minister ofjapan. shinzo abe has real concerns about a log of

attention to detail over north korea's future. he wants to insure japanese interests are not overlooked as the us warms to kim jong—un‘s vision for his country. donald trump is bullish about his aspirations, talking about a possible invitation to the us for mr kim if it goes well in singapore.“ you do invite him to the united states, would it be here at the white house or mar—a—lago? states, would it be here at the white house or mar-a-lago? maybe we'll white house or mar-a-lago? maybe we' ll start white house or mar-a-lago? maybe we'll start at the white house, what do you think? and that would be quite a photo—op. peter bowes, bbc news. as the anticipation builds for this summit, we'll have an update on the latest developments from our correspondent in the south korean capital seoul, in just a few minutes. before that summit next week, there's another one starting in a few hours' time, the g7 meeting of the world's top economies. the british prime minister has already arrived in quebec where it's taking place, but she's leaving behind yet another

storm in her cabinet over brexit. it's been a particularly tough time for theresa may, with one minister leading britain's negotiations reportedly threatening to resign. mrs may wants a stop gap plan that would see the uk stick closely to eu customs arrangements. but there is plenty of disagreement about that. our political editor, laura kuenssberg, looks back on the last 2a hours. reporter: are you about to lose your brexit secretary, prime minister? she has a lot on, but theresa may's firstjob today was to prevent disaster, to stop the man who is meant to be in charge of brexit from flouncing out. david davis was summoned to an early meeting behind the commons gates, behind closed doors. other ministers were trying to embrace the day. and one of the nice things about this beautiful summer's day is that it's an opportunity, of course, for me to have a chat with my colleagues about the important issues that we're dealing with. an hour of discussion, but back into the jag with no agreement.

david davis was threatening to quit... stop brexit! ..if the prime minister didn't put a specific date for a time limit into a government document. the plan for customs after brexit, if new ways of managing can't be found. who would budge? reporter: are you going to resign, mr davis? downing street was sweating. at stake — notjust this proposal, but the fortunes of the government itself. a nervous wait during nearly another hour of talks, but then david davis's team claimed victory. the document would, after all, include a date, with this crucial line. in other words, the brexit secretary had made the prime minister move. foreign secretary, isn't it rather a problem that the cabinet have been bullying the prime minister in public? no mistake, it's anotherfudge, not a concrete commitment to anything. the smile on borisjohnson‘s face as he left a long meeting suggests one thing. some senior brexiteers in government believe they have won.

borisjohnson, the boris johnson, the british borisjohnson, the british foreign secretary. he has warned his supporters that the brexit negotiations are reaching what he called a moment of truth and there's a risk they may not get the deal they wanted. in comments to a private dinner on wednesday night, which were secretly recorded and leaked, mrjohnson said he believed brexit was irreversible but added britain could end up, as he put it, "locked in orbit around the eu". the g7 summit is our top business story today. the group is supposed to be about co—operation between members, france, germany, the uk, japan, italy, canada and the us. but it's at its most divided in its four decade history. in fact, it's more like the g6 on one side, and the us on the other. president trump's america first trade policy has pitted the us against its allies. priya lakhani from

century techjoins me now. we can talk about g7 in a moment, let's talk about theresa may, she joined the g7 at quebec, getting off the plane, but she leaves a tumultuous 2a hours in terms of brexit, it is theresa may 1—0 david davis, the brexit secratary? this is barely, is barely a fig leaf. that's been the case since the referendum and since she was brought into power. it feels like with david davis he will throw his toys out of the pram, if i don't get what i will resign, that comes through some friends, some eurosceptics. the whole point of brexit was making

sure power went from brussels to westminster. she's the prime minister, she has to bring everyone on board but decide what's best. it feels like one man is sitting in the seat of control and that doesn't feel like the type of democracy we wa nt to feel like the type of democracy we want to be in. there's a big question as to what's happening in parliament, and what she has done is pretty smart, it's not holding us to anything, the potential hard stop date. i'm looking forward to seeing what happens next but definitely i—o to prime minister may. let's talk about the g7, the key issues are trade, whether we're going to get a deal on trade or get any further on trade remains to be seen, very unlikely. but everyone is at a different start point? i'm not sure that's the right position to be at. in an ideal world you will have the g six, looking at this and saying we're not going to retaliate, have a trade war and goat it for tat but how can you not respond to this? the

us is so powerful, trump is exercising the might of the usa, you wa nt exercising the might of the usa, you want them to come together and hit the usa in some sore spots. they're being pretty smart, canada is looking at targeting orange juice being pretty smart, canada is looking at targeting orangejuice in florida and chocolate in pennsylvania and mexico is thinking of doing the same. things are becoming more political than economic? yes, it will have massive economic? yes, it will have massive economic impacts. this will unravel decades of progress and all the work. the us did this in the 1930s with the smith horley bill, they brought in thousands of tariffs and they have thousands of petitions from separate economists. i wonder how many petitions donald trump will get this time? he has to be careful because he could affect fundamentally us companies with supply chain is built around his allies that he's alienating. you will be back with us shortly to talk about the papers. let's brief you on some of the other stories making the news. canada has moved closer

to becoming the first member of g7 to legalise the production, sale and consumption of marijuana. the country's senate has approved the cannabis act, fulfilling a 2015 campaign promise of prime ministerjustin trudeau. the government hopes the law will come into force this autumn. the french parliament has voted to ban mobile phones in schools. the hope is it will improve concentration in class, and help prevent cyber bullying. both teachers and students will be affected. if approved, the law will come into force later this year. that's our twitter question, we been getting lots of responses, keep those responses coming as to whether you think that's a good idea. kaliningrad is the western—most host city for the world cup in russia, a small enclave that's wedged between lithuania and poland. its proximity to europe means it's easier to get to for many football fans. here in britain some members of parliament have again voiced concerns about fans‘ safety. but as sarah rainsford reports, in kaliningrad, some locals are determined to prove them wrong. there is a little bit of england on

this russian street. kaliningrad is almost ready to welcome the team here and crowds of fans. some locals are even taking them into their homes. nicolai shows me the space he's offered three england supporters for free. and from the decor, it's not ha rd to free. and from the decor, it's not hard to guess why. his visitors should feel quite at home with this bathroom. the flat could be a squeeze, bathroom. the flat could be a squeeze, with nikolai's girlfriend living here too. but on match night, nicolai tells me he doesn't think his guests will be sleeping much anyway. you wanted it for free because? because it's fun, it's not about money, it's about

football, it's about friendship. we're not frightening! no, we don't have bears and guns in every room! kaliningrad was part of germany before world war two, and it still looks and feels quite european in parts. but this exclave is now part of russia, and some in britain still have concerns about fans‘ safety at the world cup. this official called fears of racism and homophobia here made up. translation: the main thing, of course, is to respect the laws of the country you visit like any tourist. you don't act like you want, you follow the customs of the country. there are traces of this city's european past even here at the local football club. these columns come from a german church that was almost destroyed during world war two. in soviet times they became part of the grand entrance here at baltica fc.

the club currently plays at the old est the club currently plays at the oldest ground in russia. in the 19305 oldest ground in russia. in the 1930s nazi troops raided here but the swastikas have long since been removed. baltica will inherit this now after the world cup. callinan's brand—new stadium. that's where nikolai's guests will watch england play —— kaliningrad. greg has already got his t—shirt. he tells me he's looking forward to his trip, although others were too worried to come to russia. there's a lot of fans here that have got fears may be. obviously the main thing stems from the political events that have gone on certainly in the past few months. doesn't faze me one bit. i think the world cup is going to be great. you won't have far to go from his hosts' flat —— he won't. the world cup will be right on the doorstep.

sara green spread, bbc news, kalinic grad. —— kaliningrad. stay with us on the briefing. also on the programme: organic molecules on mars, nasa with a tantalising new discovery on the red planet. the day the british liberated the falklands, and by tonight, british troops had begun the task of disarming the enemy. in the heart of the west german capital, this was gorby—mania at its height. the crowd packed to see the man who, for them, has raised great hopes for an end for the division of europe. michaeljackson was not guilty on all charges, the screams of the crowd testament to his popularity and their faith in his innocence. as long as they'll pay to go see me, i'll get out there and kick 'em

down the hill. what does it feel like to be the first man to go across the channel by your own power? it's pretty neat. feels marvellous, really. you are watching the briefing. our top story: days before the us—north korea summit, america's top diplomat says kim jong—un has assured him that he is prepared to denuclearise. let's stay with that now. our correspondent robin brant joins us live from seoul. we have heard from the us secretary of state that he has received personal assurances from kim jong—un that he will dismantle his nuclear programme, but it is still unclear

whether this is a proper step forward or not. yes, and the issue of denuclearisation, what that word means to either side in these talks, is at the very heart of the dispute, is at the very heart of the dispute, is at the very heart of the dispute, is at the very heart of solving it, is at the very heart of solving it, is at the very heart of solving it, is at the very heart of trying to get some semblance of progress after these two men sit down in singapore on tuesday. mike pompeo, the us secretary of state, who we learned today will be coming to seoul after the summit next week, has said that he has had personal indications from kimjong—un, he has had personal indications from kim jong—un, who he he has had personal indications from kimjong—un, who he met several weeks ago, that north korea and its leader is willing to denuclearise. now, for the americans that means complete, verifiable and irreversible denuclearisation, essentially getting rid of their devices, the missiles that possibly deliver them, prove to the world they are doing that, proved to the world they can never go back. to north korea, that means something

very, very different. the first thing is that kim jong—un very, very different. the first thing is that kimjong—un has very, very different. the first thing is that kim jong—un has spoken of not just north thing is that kim jong—un has spoken of notjust north korea denuclearising, but everyone else, including the united states, and only then would they consider handing over their devices and missiles. i think what we are likely to get, if indeed there is any progress on tuesday, is the beginnings of a timetable, maybe. the beginnings of some kind of reassu ra nces the beginnings of some kind of reassurances from the americans towards north korea, to try and help build trust, and maybe in return for that, from kim, the commitment to some kind of timetable, to look at addressing the issue of denuclearising. very slow progress, possibly. thank you very much indeed. nasa says new discoveries on mars could mean some sort of life is present on the surface. the red planet might not been home to little green men, but it does have organic compounds, as well as a source of methane gas, both of which could have

a biological origin. andrew plant reports. it is not evidence of life on mars, not yet, anyway. but it could be one step closer. ta ntalising not yet, anyway. but it could be one step closer. tantalising signs of potential biology. organic molecules and methane. both could be an indication that something's happening on all beneath the red planet's surface. we don't know that there was ever life on mars. there is the organic molecules that we have found are not specifically evidence of life, because there are other sources of making those molecules, including things that are nonbiological in nature. the samples have been taken by a curiosity rover, slowly exploring the chemistry of mars, rolling down into the billion —year—old rock of what was once an ancient lake. 9596 of the methane on earth is produced from

biology, is produced from termites or rice paddies or cows or sheep or termites, et cetera. because of that, there has always been this interest in mars methane. at the moment it is not clearjust how common life might be on other planets. we only have one example, here on earth. at discovering life on our next—door neighbour, even if it is only little green microorganisms, would tell us a lot about both ourselves and the likelihood of life outside our solar system. now it is time to get all the latest from the bbc sports centre. here's our briefing on some of the key events happening later. in the next couple of hours, the former south african president jacob zuma will appear at durban high court accused of corruption in a $2.5 billion arms deal. later, in london, eltonjohn will give a lecture on hiv in memory of diana, princess of wales. he will set out his vision for an aids—free future, and call on governments and the private sector to fulfil the united nations‘ goal to end the disease by 2030.

and also in london, men's fashion week kicks off, with international and homegrown british designers showing off their latest collections until monday. now it is time to get all the latest from the bbc sports centre. hello, i'm tulsen tollett. coming up in your friday sport briefing: the golden state warriors can wrap up the nba finals later with victory over the cavaliers in cleveland. rafael nadal continues his bid to win an 11th french open title. and we will show what happens when the women's steeplechase is set to the men's height by mistake. the golden state warriors could lift the nba title later on friday night if they beat the cavaliers at home in cleveland. golden state hold a 3—0 lead in their best—of—seven series. last time out, the cavs started the stronger, lebron james once again standing out from the rest. but warriors forward kevin durant was the hero, a late three—pointer sealing the win, and james admitted the warriors are a more balanced side than the cavaliers.

from a talent perspective, if you look at golden state, from their top five best players to our top five players, you will say that they are stacked better than us. i mean, that's just to speak truth. kevan durant, and you have two guys with mbp is on their team, and a guy in clay who could easily be on the team and carry the team, scoring a0 in the quarter before, and you have dray, who is arguably one of the best defenders and minds in our game. rafael nadal will take onjuan martin del potro in their french open semi—final later, as he looks to take another step towards an 11th title at rolland garros. after rain delayed the match overnight, the world number one concluded his quarter—final on thursday, and it didn't take him

long to turn things around against diego schwartzman. the spaniard was simply too good as he wrapped up the match in four sets. simona halep has another chance to win her first grand slam title after beating garbine muguruza in the french open semi—finals. the world number one raced through the first set, taking it 6—1, before coming through 6—a in the second. the romanian has already lost twice in the final at roland—garros. this time she will face the us open champion, sloane stephens. she also came through in straight sets after beating her fellow american madison keys 6—a, 6—a. european champions portugal warmed up for the world cup with a 3—0 win over algeria in lisbon. goncalo guedes scored twice for the hosts. while elsewhere, england were 2—0 winners over costa rica, thanks to goals from marcus rashford and danny welbeck, and iceland accounted for ghana in reykjavik. and team sky's gianni moscon has

moved into the overall lead of the criterium du dauphine after stage four. moscon finished ninth in the tour‘s first mountain stage in france. quick—step floors rider julian alaphilippe took the stage victory. there was drama aplenty at the diamond league meeting in oslo on thursday, with the barriers in the women's steeplechase having been set to the men's height. american world champion emma coburn had been gesturing, trying to bring officials' attention to the blunder. they tried to adjust it mid—race, at one point the field hurdling it after it had been lowered at one end but left too high at the other, with several athletes falling over the sloping bar. you can get all the latest sports news at our website. that is bbc.com/sport. but from me, tulsen tollett, that's your friday sport briefing. and tell me what you think

about our talking point today. in france they are going to be banning mobile phones in schools from septemberfor banning mobile phones in schools from september for kids banning mobile phones in schools from septemberfor kids up banning mobile phones in schools from september for kids up to the age of 15. we have had so many tweets about this. many of them, the majority, by have to say, are in favour of the french government. eric says absolutely a good thing, only cellphones restricted to pa rental only cellphones restricted to parental and emergency contact should be allowed. i do believe cellphones are not allowed at all. emily says here in the us the number of lives in danger from school shootings means it is a sad day when you need a phone because you are not safe in public, but many people are in favour. another viewer says i am happy france is doing this, children have too much freedom. keep those opinions coming. from us, goodbye. hello there, good morning. we had a

few showers around yesterday. some localised flooding, actually, in central parts of scotland. but on the other hand we just had the warmest day of the year so far in wales. lovely blue skies here. some sunshine over the next couple of days, not just today, sunshine over the next couple of days, notjust today, but still the chance of catching one or two showers. the worst of the storm is staying over the near continent. we got a few home—grown ones to worry about in the next couple of days or so and we've still got this line of weakness, if you like, from wales afterwards the humber and north yorkshire, so a more showers developing here, a few towards the south—west of england, and some slow—moving downpours again the western pa rt of slow—moving downpours again the western part of northern ireland and particularly thundery downpours therein central scotland. nothing to move them on at all. large parts of the uk will be dry, temperatures may bea the uk will be dry, temperatures may be a shade lower than they were yesterday. the sunniest skies south—west scotland and north—west

england and perhaps later in the south—east. a lot of those storms, the showers will tend to fade away overnight. we will see a fair bit of cloud coming into eastern areas in chilly of the north—east england and eastern scotland as well. and here it will start rather grey and misty, some patches of fog tending to break up. sunny spells developing more widely. showers around on the whole the saturday, most of them concentrated again across central and northern parts of scotland, where they could he slow—moving, heavy and thundery. so temperatures typically in the low 20s, cooler around those north sea coasts. as we head into the weekend we have still got high pressure across most of the uk but it is not completely dry. we have also got lower pressure over the near continent threatening to bring some downpours. and on sunday they are more likely to be through they are more likely to be through the channel islands, through the in the channel islands, through the in the channel, a few showers further north, perhaps, but most of them in scotland. probably more widespread,

again heavy and thundery in scotland. large parts of the uk, again, seeing temperatures in the sunshine into the low 20s. so for most of us not a bad weekend at all. now, at one stage it looked like this weather front was going to bring some much wetter weather close to our shores into the south—east. but pressure is high enough across most of the country to keep that day. mind you, the very heavy rain is not far away from kent. most places will be dry on monday, with sunny spells. some showers again to the north, maybe over the pennines into scotland, but not quite as many and not quite as heavy, and those numbers are not changing much at all. this is business briefing. leaders arrive for the g7 summit in canada. but with tensions high over president trump's america first policies, is it more a case of the g6 versus the us? plus, a change of flight path. we meet the former telecoms boss now battling to turn around south african airways.

and on the markets, asian shares on the retreat, with investors focusing again on that widening rift between the us and its major trading partners.
