welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is mike embley. our top stories: after meeting japan's prime minister, donald trump declares he's optimistic about progress at the north korea summit i really believe that we have the potential to do something incredible for the world, and it's my honour to be involved. but other leaders of the world's most powerful nations gather in canada for the g7 summit, facing deep divisions with the us on trade. the senate in canada votes to legalise recreational cannabis, making it the first of the g7 countries to legalise the production, sale and consumption of the drug. and was the red planet always a dead planet? nasa says it's found something that suggests there might have been life on mars. the us secretary of state has said he's received a personal

assurance from kim jong—un that north korea is prepared to dismantle its nuclear programme. that may or may not be a breakthrough ahead of next week's planned summit in singapore. president trump has been holding talks with japan's prime minister, and promised shinzo abe improved trade links, and a serious effort to retrieve japanese citizens kidnapped by north korea. jane o'brien reports. with the clock ticking down to tuesday's summit with kimjong—un, donald trump was visibly excited. i think it's going to be a very fruitful meeting, an exciting meeting, i think we're going to get to know a lot of people that our country never got to know. so the summit now seems to be more of a getting—to—know—you session, rather than a complex and high—stakes negotiation — another insight into mr trump's rather unorthodox approach. i don't think i have

to prepare very much. it's about attitude, it's about a willingness to get things done. but i think i've been preparing for this summit for a long time. that is in contrast to the rather more direct approach taken by the secretary of state, mike pompeo, when asked if both sides were closer to agreeing on a definition of "denuclearisation". yes. reporter: can you describe that a little bit? no. laughter announcer: ladies and gentlemen, the president of the united states and the prime minister ofjapan. but forjapan‘s prime minister, shinzo abe, here in washington to ensure his voice is heard, the direct threat from north korea remains. these drills are a practice for the ballistic missiles that can already reach tokyo, with or without nuclear warheads. but mr abe seems to have been sidelined. kim has met with china's president xi, south korea's president moon, and mr pompeo.

mr trump, meanwhile, is already thinking of other photo ops with mr kim. reporter: sir, if you do invite him to the united states, would it be here at the white house, or at mar—a—lago? maybe we'll start with the white house. what do you think? mr abe has invested a lot of time building a personal relationship with mr trump. but, as other leaders of us allies have discovered to their cost, friendship does not always come up with benefits. and, with mr trump so keen for his own success, mr abe might be right to worry. jane o'brien, bbc news, washington our north america correspondent, peter bowes, told me more about these comments from the trump administration might mean. well, it's looking to me like we're getting different levels of expectations for this summit next week from donald trump and from his secretary of state. we just heard donald trump perhaps playing down expectations a little bit, saying that he doesn't have to be overly prepared, at least that's what he's

suggesting, for this meeting. he doesn't want to get into detail on this first meeting, suggesting that it will be a longer—term process. but we also heard from mike pompeo, the secretary of state, sounding rather more bullish. he's met kim jong—un on two occasions, and it seems, on the basis of their conversations, he is rather more hopeful of something substantial coming out of this. he has indicated to me that he is prepared to denuclearise, that he understands the current model doesn't work and he's prepared to denuclearise and until he understands that we can't do the way we've done it before, just has to be thick and bold and we have to make major changes. we can't stay through this over the years. mike pompeo sounding bullish

about denuclearisation. they are also concerned that mr trump may end up doing a deal about the long—range missiles, if he can, the ones that may threaten the us, and not the others, that threaten japan and its neighbours. yes, the concern from japan, i think, is on the detail of what might be agreed at this summit. whether it's to do with hostages, some of them have been hostages in north korea for a very long time, or as you say, nuclear weapons. whether this will be denuclearisation involving all nuclear weapons, long—range, medium—range and short—term. long—range, of course, would have an impact for the united states, but short and medium—term, are they part of the deal? that would be very significant for closer nations, like japan, and i think the japanese prime minister wants to make sure that that level of detail is part of the negotiation. well, that trump—abe meeting was a precursor to both leaders heading to canada for the g7 summit, which brings together the heads

of the world's biggest economies. awkward moments are expected, mainly because of the tariffs imposed by the trump administration on aluminium and steel imports from g7 allies, including france and canada. prime ministerjustin trudeau is sending a strong message to the us president. translation: we see that there is a lot of pressure within the united states to perhaps revise this laughable statement that canada, france and nato countries could represent a threat to america's national security, when in reality, we are the best allies that the united states has had for a long time. the french presidnet, emmanual macron, has also the french president, emmanual macron, has also had his say. in a tweet, he said: the bbc‘s gary o'donoghue is in quebec for the g7. he told us it'll be a difficult summit for those involved.

it promises to be an extremely awkward summit between seven country, seven economies, that are meant to be in lockstep, and have been in lockstep in terms of their attitude to trade and to other international matters for a number of years. so there's a good reason why many people are calling this the "g6 plus one", and this will be the first opportunity that those allies have face—to—face to tell donald trump what they think about those tariffs. and you heard there the prime minister of canada, the host country, describing them as laughable. he's previously called them insulting and unacceptable. the european union, and those countries who are in the g7 from the eu, have also said that they are going to retaliate, as is canada, to those tariffs. so there's going to be a lot of pressure on the american president when he arrives here on friday. there will be some room for

agreement between these countries. they've been working on other initiatives, such as the education of girls around the world and progress for women in leadership issues. but on things like trade, on things like economic development, on things like some international affairs such as the iran nuclear deal, the moving of the us embassy from tel aviv to jerusalem, all these things have created huge tensions between these countries which would normally be allies. dario donoghue for us in quebec. —— gary owed on the. the senate in canada has voted to legalise recreational cannabis. it fulfils a campaign promise by the prime ministerjustin trudeau and makes the country the first of the g7 states to legalize the the production, sale and consumption of the drug.the initial timeline for legal pot sales called for it to be available byjuly ist, canada's national day, but august or september now appears more likely. sales to anyone under 18 would be banned under federal law but provinces and territories could set their own age limits. senator tony dean voted for legalisation, and we can speak

to him in ottawa. thanks very much for your time. canada already legalised cannabis for medicinal use, why recreational? because we've recognised in canada, and the government has recognised, the harms of cannabis, particularly to young people. we have the problem of world leading consumption of cannabis by young people, one in 320-25 cannabis by young people, one in 320—25 —year—olds, one in 515—19 —year—olds, there are health problems associated with that and there are health problems,,, problems for in digitised and other canadians who are world overrepresented in the criminal justice system. products aren't

often tested for potency, they are often tested for potency, they are often co nta m i na nts, often tested for potency, they are often contaminants, so moving to a legal and regulated system will be safer for users and combined with harm reduction and public health initiatives, this will start to tackle issues we have with cannabis in canada. senator, briefly, in a nutshell, fill in some of the detail. will it be widely available, oi’ detail. will it be widely available, or only specific retailers. will people be able to grow their own? inaudible we can see senator dean talking but we have lost the audio feed. we will get back to it if we can. senator dean. we hope to be speaking to him again injusta dean. we hope to be speaking to him again injust a moment. as the death toll rises from sunday's volcanic eruption in guatemala, the most

violent in four decades, the government has asked for urgent international assistance. it's now confirmed 109 people have died, but many others are still missing. worst affected are villages on the slopes of the fuego volcano. we went with one man as he returned to san miguel los lotes searching for his family. eddie sa ntiago's desperate search for his family following the volcanic eruption in guatemala. a police sergeant who led an elite unit in baltimore that went dramatically rogue has been sentenced to 25 years in prison. wayne earljenkins sobbed in court and apologised for robbing baltimore citizens, planting drugs on innocent people and re—selling seized drugs. andrew plant reports. a drug bust in baltimore. a small, elite team of officers breaking open open a safe, thousands of dollars in drug money inside. but what's been captured on camera is far from the full story. in fact, they'd already opened the safe and stolen bundles of cash

before closing it up and putting on the whole performance. the gun trace task force was led by sergeant waynejenkins, a decorated former marine, arrested last year and now convicted of corruption on a massive scale. jenkins and his team would steal money, plant evidence, and even re—sell drugs they had taken from dealers. these officers would drive their car, gun it towards a group of black males on the corner, most of the people they stopped were black males, then they would stop it and see who would run. well, these officers are riding around in unmarked cars. so if you have an unmarked car coming at you, and 300—plus murders, you're going to feel that, oh, my goodness, it's probably someone's coming to shoot up the sidewalk. jenkins didn'tjust stealfrom criminals. prosecutors showed evidence of him building up the tools needed to commit crimes of his own. the jury was shown axes, machetes and crowbars, as well as black masks found in his van.

jenkins has now been given 25 years in jail, alongside evodio hendrix, daniel hersl, jemell rayam, maurice ward, marcus taylor, and momodu gondo — all but one member of the gun trace task force convicted of racketeering, robbery and falsification of records. the unit's corruption has led to 1,700 criminal cases being thrown out, their evidence now impossible to trust. the damage to the police's public image, though, much more difficult to measure. andrew plant, bbc news. you can find more details on this story on our website, when cops become robbers — inside one of america's most corrupt police squads. simply go to bbc.com/news. stay with us on bbc news. still to come: how does donald trump's foreign policy go down with his supporters? we are at a baseball match to find out. 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. this is bbc news. the latest headlines: after meeting japan's prime minister, donald trump says he is optimistic about progress on the issue of denuclearisation at his summit with kim jong—un. meanwhile, other g7 leaders gathering in canada are at odds with president trump over his imposition of trade tariffs. the british prime minister is now in quebec for the g7 summit, but she left behind another storm in her cabinet over brexit. it has been a chaotic 2a hours for theresa may, 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. here is our political editor laura kuenssberg. 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. 0ther 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 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 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. laura kuenssberg reporting. 0ur europe editor katya adler assesses the eu's reaction to the latest brexit shenanigans in london. this was a very big day for brexit — in the uk, that is. but in the eu, it's

seen as a significant if limited step forward. why significant? because, four weeks after these rows, there was no progress made in brussels in the negotiations about the issue the eu warns could bring the brexit bill crashing down — the irish border conundrum. and this, they say, is the absolute key of it. and this is why they are looking today at the paper to see whether it helps them in that at all. tomorrow we will hear from michel barnier, the chief brexit negotiator for the eu, that the eu sees many holes in this paper, and have many further questions. this will be not the end of the irish border chapter, because the eu of course wants cast—iron legal guarantees that there will be no reintroduction of a border between northern ireland and the irish republic after brexit.

today, the uk came with its proposal, and this means the two sides can get back to the brexit table. but, despite the criticism, there will be words of encouragement as well for the uk, because from here they can see that theresa may is in trouble from all sides, and they do not want to help, here in brussels, to unseat her altogether. let's take a look at some of the other stories making the news: a software bug means millions of facebook users may have unknowingly posted private information to the public. the glitch set some users‘ posts to be shared to everyone, even if the user had chosen a more restricted option, such asjust share with friends of friends. facebook has apologised and says the problem is fixed. 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. now, over the past few weeks we have

heard endlessly from politicians and pundits about donald trump's foreign policy. so what are his voters currently thinking, those who put him in the white house? nada tawfik has been finding out, at a baseball game in pennsylvania. president trump has turned american foreign policy into something of a must—watch sporting event. look away too long, and risk missing an important play. pennsylvania was one of the key states that swung the election, and here, his loyal base approves of his strong—arm tactics. we asked his supporters at the fightin phils game to grade his diplomacy so far. susan likes president trump's unpredictability. the hard—core, rough face that he's had comes out, there's no question about that. but i think it's somewhat refreshing, and no—one is expecting it.

critics of this administration believe the world is less safe now that the united states has pulled out of the iran deal, the paris climate accord, and has provoked a trade war. but they have been unable to discredit president trump in the eyes of his supporters. from iran... they probably already have nuclear weapons. we gave 'em all that money, skids of money, and what did we get out of it? nothing. ..to imposing tariffs on allies. i realise what they could do to us, well, we might have to pay for that, but it has to be done to keep the country safe. i'm all for keeping the country safe. and they reject the notion that these actions will leave the us increasingly isolated. america will never be alone. the billions of dollars that people come to us for aid and help, we're never gonna be alone. in fact, the upcoming north korea—us summit is further proof to them that america is winning.

he's going to do what he thinks is right. he's not going to kowtow to anybody. do you think he's going to be able to make a deal on north korea? maybe, maybe not, but at least he's trying something. what we've done in the past hasn't worked. we also asked those who didn't vote for president trump to grade his foreign relations. they were less generous. his ego and everything gets in the way of his decisions. i don't like his policies. i think he's antagonistic. i don't know how anybody can take anything that comes out of his mouth seriously, because tomorrow it'll be something different. in baseball, they say attitude is everything, and that is also president trump's guiding principle in foreign policy — to project american strength. and, while his unconventional approach is often criticised, with his base, it's a hit. nada tawfik, bbc news, in reading, pennsylvania. nasa believes it has detected organic molecules on mars,

raising the possibility that there was once life on the planet. the space agency says its mars curiosity rover discovered the molecules in rocks dating back three billion years. we found organic molecules in rocks from an ancient lake bed. those organic molecules could have come from life. we don't know that there was ever life on mars. there is — the organic molecules that we found are not specifically evidence of life, because there are other sources of making those molecules, including things that are non—biological in nature, things like meteorites, 01’ even i’ock processes. we can attribute geology all by itself, without life, to making organic molecules, and the information that we have doesn't tell us which source is responsible for what we have. a reminder of our top story: america's top diplomat has said the north korean leader has indicated to

him that the country is willing to denuclearise. they said they are reaching a common definition of what that word means. hello there, good morning. in wales, it's just been the warmest day of the year so far. here, 27 degrees. day of the year so far. in scotland, we had some slow—moving, thundery downpours yesterday, bringing some flash—flooding. and, across the southern half of the uk, much more cloud, and there's sufficient cloud over the next few days to bring the chance of one or two heavy and perhaps thundery showers. again, the worst of the storms, the more widespread storms, are likely to stay over the near continent. but we're looking at a few home—grown downpours in the next couple of days or so. difficult to pick out exactly where they'll be. but we've got this zone of weakness on friday, from wales up towards the humber and north yorkshire, where we could see a few more showers developing, perhaps towards the south—west of england, too, hence the odd slow—moving downpour across western

parts of northern ireland, and particularly central scotland — some thunderstorms here. large parts of the uk will be dry. best of the sunshine, south—west scotland, north—west england, and later in the south—east of england. those storms in the north will tend to fade away. most of the showers in england and wales fading away, too. but a fair bit of low cloud coming into eastern scotland and eastern england overnight, and a chillier night, actually, across eastern scotland and north—east england. quite a grey start here. a lot of that low cloud, misty weather, will tend to burn off. we will see sunny spells developing more widely. quite a grey start here as well. a lot of that low cloud, misty weather, will tend to burn. we'll see sunny spells developing more widely. very few showers on saturday, the bulk of them are going to be in scotland, and these again will be heavy and thundery. not moving at all, so if you catch one, you will know about it. but it seems to be all or nothing again, and most places will have a dry day.

now, we've got very little wind to stir things up at all, or to move things around. this lower pressure towards biscay threatens to bring some thunderstorms our way. at the moment, it looks like on sunday they're more likely to be through the english channel, affecting the channel islands. the odd shower further north, but again the bulk of the showers will be in scotland. probably more widespread showers on sunday, and again, heavy and thundery. but large parts of the uk dry, and temperatures into the low 20s. now, at one stage it looked like this weather front will bring all these downpours into the south—east of the uk. but now, we've got sufficient high pressure to just keep that at bay. mind you, it's not far away from kent on monday. 0therwise, some good spells of sunshine. again, no wind at all. a few showers, not quite as heavy this time for scotland, but one through the pennines, too, and temperatures 22, maybe even 23 degrees. and, looking ahead to tuesday and wednesday, not a great deal changes. most places will be dry. temperatures in the low 20s in the sunshine. mid—week, though, things may change. this is bbc news. the headlines: the us secretary of state has said

kim jong—un has indicated to him personally that north korea is prepared to denuclearise. president trump has been talking with the japanese prime minister ahead of next tuesday's meeting, and said he's optimistic about progress with north korea on the nuclear issue, and on retrieving japanese citizens who've been kidnapped. leaders of world economic powers are preparing to confront donald trump over the new us tariffs on steel and aluminium imports. before joining them for the g7 summit in quebec, donald trump complained that france and canada were also hurting the american economy. the american space agency says it's detected organic molecules on mars, raising the possibility the planet may have harboured life. nasa scientists say the mars curiosity rover discovered three different types of organic molecules five centimetres down, which are not evidence of life in themselves, but could have come from living organisms. now on bbc news, hardtalk.
