a warm welcome to the programme, briefing you on all you need to know in global news, business and sport. canada has announced plans to ban single—use plastics that are most harmful to the environment and the world's oceans. it will cover items such as straws, cutlery, bags and cotton buds, and will come into effect in two years‘ time. have you tried? how easy or hard is it to stop consuming single—use plastics? send us your top tips. just use the hashtag #bbcthebriefing. the trump administration says it could still apply trade tariffs if itjudges that mexico hasn't done enough to limit migration to the us. secretary of state mike pompeo says

he expects to see results within four to six weeks. a deal negotiated last week includes more troops being sent to mexico's southern border to stem the number of arrivals. if that doesn't work, the us wants further measures to tackle the issue. david willis reports from california. they come huddled on flimsy rubber rafts , they come huddled on flimsy rubber rafts, across the river that forms the border between guatemala and mexico. for many, the first step of the journey that it is hoped will end on american soil. translation: i know the path along the border well, this man says, and it's very difficult. but this is myjob, to get to the united states. waiting to greet these migrants, however, as they came ashore were mexican

immigration officers, all part of the new deal mexico has struck with the new deal mexico has struck with the united states in order to avert the united states in order to avert the threat of punitive tariffs on mexican goods. approval for the threat of punitive tariffs on mexican goods. approvalfor part the threat of punitive tariffs on mexican goods. approval for part of the deal now rests with the mexican legislature. it's all done, and they have to get approval, and they will get approval. if they don't get approval, we will have to think in terms of tariffs, or whatever, but it's just another aspect of what we've done. it was all done because of the tariffs. migrants are crossing the us border with mexico at the rate of more than 100,000 a month. many come from elsewhere in central and southern america, and the trump administration wants mexico to do more to stop them. it is hailing this agreement as a possible breakthrough. is hailing this agreement as a possible breakthroughm is hailing this agreement as a possible breakthrough. it reflects diplomacy at its finest. it shows the enduring strength as well of the relationship between the two countries, and it's a significant win for the american people. as part

of the deal, mexico has agreed to send 6000 national guard officers to the border with guatemala, which migrant activists have warned could make it all the harderfor those seeking refuge from violence and oppression in other parts of central america. translation: i have heard it said that we are going to militarise the southern border, mexico's foreign minister told reporters. that's not true. we've been talking about deploying the national guard there for a while. we are simply doing it faster than we are simply doing it faster than we are originally intended. the trump administration has given mexico up to six weeks to curb the number of illegal immigrants crossing into the united states. otherwise, it will impose tariffs of up to 25%, prompting fears of retaliation on the part of one of its biggest trading partners. new york's mayor says there is no indication a helicopter crash

in the city is an act of terror. the chopper came down on top of a 54—storey building, killing the pilot. the authorities are investigating whether it had clearance to fly in the area. ramzan karmali reports. smoke fills the new york air, just moments after a helicopter crashed into this skyscraper in midtown manhattan. the crash took place close to the tourist hot spot, times square. for those inside, it was clear that something wasn't quite right. i was on the 20th floor, and everyone was just sitting in chairs, working, and we felt the tremor. and what did it feel like? it felt like a very small earthquake. thankfully, no debris fell from the building, despite the obvious impact the helicopter had on the building.

firefighters were very quickly on the scene to put out the fire. donald trump was quick to reassure new yorkers. many are still traumatised by the events of 9/11. i want to say the most important thing first. there is no indication at this time that this was an act of terror. and there is no ongoing threat to new york city. based on all the information we have right now. the pilot of the twin—engine helicopter died, and was the only person on board. weather conditions were poor, with heavy rain and fog. now, officials say that why the aircraft was flying in such poor weather will be part of the investigation. let's brief you on some of the other stories making the news: researchers say a malaria study which combines medical surveys with data collected on mobile phones represents a major step forward in tackling the disease. the study tracked the movements of people in the chittagong region of bangladesh by using anonymous data from their phones. the project aims to predict where new outbreaks spread by people carrying malaria parasites

are likely to occur. chinese officials say record levels of rainfall in the south of the country have left five people dead and stranded thousands. hundreds of homes and thousands of hectares of crops have been destroyed. state media reports say the downpours are expected to continue for another four days. the us government has declared it is gravely concerned about the proposed amendments to hong kong laws that would allow suspects to be extradited to mainland china. on sunday, hundreds of thousands rallied against the bill in hong kong. many fear it will make it easier for china to target political opponents there. the race to become the next conservative leader and prime minister here in the uk is officially underway. the names of the ten candidates who have gained enough support from fellow tory mps were announced on monday evening in westminster. they all now face the first ballot on thursday, when conservative mps will cast their votes.

mark davies is the ceo of the strategy consultancy camberton. he is also a member of the conservative party, so ultimately when we get down to two you will have your say. i will. but looking at those in the running, the ten, is this boris johnson's at those in the running, the ten, is this borisjohnson‘s race to lose? at those in the running, the ten, is this borisjohnson's race to lose?|j think this borisjohnson's race to lose?” think the issue is whether the conservative mps put borisjohnson through, if they do, he has 59% support on the basis of current polls. what is interesting is that the mps on the whole are more left—wing than the membership. so i think there are some mps who would really like not to put borisjohnson through, but probably can't see a way to avoid doing so. as things currently stand, if he goes through, he is going to win, so the answer to your question is yes, it is his to lose. what about the other

contenders? michael gove of course has been dominating the headline since the beginning of the weekend, and this morning, if you look at the front pages, it is mainly him on the front pages, it is mainly him on the front page. he is, partly because of his campaign revelations that make cocaine revelations, and partly because he is the only one to have a go atjohnson, alluding to the last campaign and saying boris, don't drop out. he decided to have a direct pop, the others didn't do that. i thought the person who came out best yesterday was jeremy hunt, partly because i didn't think that michael gove had a great day, and when they are looking to put somebody in front of the membership, alongside boris, there's really at the moment only one place to be taken, and it's probably going to go to hunt or gove. he is a remainer, jeremy hunt, he is seen as calm, perhaps a safe pair of hands, but whoever gets the job, many are arguing it is a really poisoned chalice, and this will be a really

brutal, bitter and divisive process. absolutely, the parliamentary arithmetic has not change just because we are about to change leader, but what was good from a jeremy hunt perspective was the fact that penny mordaunt came out to back him, she eventually decided she would support hunt, and she is a key brexiteer, so the fact that she who —— he, who was seen as a remainer, got her backing is really significant. he already had liam fox, but penny mordaunt was expected to run, and didn't, and has come out onjeremy to run, and didn't, and has come out on jeremy hunt's side. we will be looking later at what the papers are saying about this race and some of the other stories, in a news briefing. the us envoy for africa will leave for sudan on wednesday to urge the ruling military council and pro—democracy opposition groups to resume talks.

tibor nagy will call for an end to attacks against civilians. on tuesday, the regime took journalists to see hospitals which they claimed were ransacked by protestors, but as our africa editor fergal keane reports, the propaganda tour didn't go as planned. it must have seemed like a good idea to somebody — showjournalists the government's side of the story. but, as we approached our destination, the ominous reality loomed into view. the rapid support force, a militia that is terrorising civilians. they are known here as the janjaweed, because of their past atrocities in da rfur. they were camped outside the clinic we were being taken to. we were shown ransacked offices — the work of protesters, our minders claimed. the militia had followed us, and were camera—shy. tony, roll on me, roll on me. officials pleaded with them so that we could film.

this is supposed to be a propaganda trip, the government showing us the iniquities of the other side. but what it is actually turning into is a farce, because as we're going on the tour, the rapid support forces are interfering. gives you an indication of the real story here. that, we would discover, was very different from the official version. translation: this is a hospital where damage was caused by the revolutionaries. they completely destroyed the equipment, medicine and furniture. do you really believe that? it was definitely attacked and destroyed. we can't confirm who did it, we can only confirm that it was attacked. but a witness who didn't want to be identified told us it was the militia who attacked.

we crossed to omdurman, this time, a hospital visit designed to show life returning to normal. for the last two days, this hospital was closed because of insecurity in the area. now, sick people crowded in, waiting for help, but too little available. without intending to, like so much of this propaganda journey, the government has given us an insight into the anger which fuels the protest movement — in this case, the chronic state of the health services. the family of 45—year—old ali omar hilal were mourning. he died in what they said was a diabetic coma. his younger brother lay nearby, in shock. the family had struggled to find medical help, amid the chaos of recent days, in a country being pushed beyond consolation.

stay with us on bbc news. still to come: sending plastic packing. canada says it will phase out single use items like straws and bags by 2021. 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 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 to the division of europe. michaeljackson was not guilty on all charges. the screams of the crowd, a testament to his popularity and their faith in his innocence.

as long as they'll pay to go and see me, i'll get out there and kick 'em down the hill. what's it feel like to be the first man to go across the channel by your own power? it's feels pretty neat. feel marvellous, really. you're watching the briefing. our headlines: a pilot's died after crashing his helicopter into a skyscraper in new york during bad weather. the us warns mexico it will impose trade tariffs if their plan to reduce border crossings into the us falls short. a pilot's died after crashing his helicopter into a skyscraper in new york during bad weather. the little island of porto santo near madeira has begun an experiment to store power in the batteries of electric cars as a back—up to the island's electricity grid. the cars top up their batteries

from solar power when the sun's shining, then return that electricity back to the island to power people's homes at night. some experts expect this form of energy storage will become a global trend. from porto santo, our energy and environment analyst roger harrabin. the savage beauty of porto santo a tt ra cts the savage beauty of porto santo attracts tourists to love nature. but people need energy, and the way it is generated here is damaging nature. this pollution is coming from the diesel generator which powers the island's homes. transporting the diesel is expensive and it is fuelling climate change. the local government want clean, renewable energy instead. but wind power and solar power band flow, so they need a way of storing energy for use at night time. here is the chosen solution. the electric car,

but not as we know it. in future, electric vehicles here will be fitted with a reversible battery, which stores energy for the electricity grid. so how does a reversible battery work? when the sun is shining the electricity flows out of the grid, down the cable and into the car. then it is stored in the battery until night time, when it flows back out of the car, up the cable, and into the grid, to power people's homes. it is a huge innovation. the car is smart, so it keeps enough power for itself to be driven. the car is only used part—time for its mobility function, and so the rest of the time it is available next to an electricity grid to be used for the grid. the firm that is installing the reversible battery system believes the technology will transform our relationship with our cars. what we're doing here is really exciting.

normally you would think having a car costs you a fortune, a lot of money. if you have a card that can feed electricity back into the grid you can actually earn money during time it is parked. yourfeedback and earn money, so it really changes the whole idea of owning a car. on porto sa nto, whole idea of owning a car. on porto santo, some whole idea of owning a car. on porto sa nto, some police whole idea of owning a car. on porto santo, some police are already powered by electricity. to run an effective backup for the local grid, half the cars on the island, like this electric taxi, will need to store power, as well as use it. so is this the road to the future? well, a couple of years ago if you had suggested car batteries could play a major part in supporting an electricity grid, a lot of people would have laughed. but that is exactly what has happened. the electricity revolution is going to create a lot more surprises. here's our briefing on some of the key events happening later. we begin with nicola sturgeon, the first minister of scotland,

visiting brussels for a briefing with the european policy centre to discuss the relationship between scotland and the eu after brexit. later on today, defence lawyers for the 12 catalan leaders charged over last year's bid for independence from spain are due to take the stand for a final time this morning, as the leaders' trials come to an end. and finally, french graffiti artists ella and pitr are due to unveil europe's largest ever street art piece. the work, on the roof of paris expo porte de versailles, will cover 23,000 square metres. now it's time to get all the latest from the bbc sports centre. hello, i'm tulsen tollett, and this is your tuesday sport briefing, where we start with the news that on mondayjapan began their quest to reach a third straight women's football world cup final, with a goalless draw against argentina, who earned their first ever point at a world cup. despite numerous chances forjapan it ended level,

meaning england are top of group d after they beat scotland on sunday. while kadesha buchanan's goal on the stroke of half—time saw canada beat cameroon 1—0, the two other teams in group e, new zealand and netherlands, play later on tuesday. in men's european qualifiers, three second half goals were enough to see spain beat sweden in madrid. sergio ramos and alvaro morata penalties were added to by mikel oyarzabal‘s goal and it means spain have taken maximum points from their four games, moving them five points clear at the top of group f. south africa are still yet to win a game at this year's cricket world cup after their match with west indies in southampton was abandoned due to rain. the proteas came into this game having lost their first three played. they were two wickets down when the showers started in the south of england and their next chance for a win will be when they play afghanistan on saturday. on tuesday it's sri lanka and bangladesh in the south west english city of bristol. both sides enter the contest having played three games with one win

each, but bangladesh come into it off the back of a heavy defeat to hosts england. and their captain is also wary of making predictions based on his side winning the last time they played each other. whatever happened in the past, i think we shouldn't think about it. like i said, england, even england, the same question was being asked twice. what is going to happen? we lost badly. so nothing is going to work that way. we have to play and play hard, and try our best to win the match. defending champions and pre—tournament favourites united states get their women's world cup campaign underway later on tuesday against thailand. the usa are aiming for their fourth world title after victories in the first tournament in 1991, in 1999 and again four years ago. as well as thailand, usa also face chile and sweden in group f.

we have all those expectations for ourselves. we don't need anything outside. we have high standards, we wa nt to outside. we have high standards, we want to win, we want to come out of the group with nine points. we want to move onto each of the games after that. i thinkjust the more that we kind of bond and come together as a group, you will be able to see that, you know, on the field. stage three of the criterium du dauphine heads out in the coming hours and it's a 177km flat route from le puy—en—velay to riom. last monday, belgium's dylan turns edged out guillaume martin in a sprint finish while three—time champion chris froome moved up to eighth. now, we've seen videos of marcelo junior before, which means his dad, the real madrid left back, is proficient on instagram — or his son is pretty good. probably the latter. his name is enzo and he's nine years old. and of course, he's signed up to the spanish giants, but too young to be part of zinedine zidane's rebuilding job at the bernabeu just yet.

you can get all the latest sports news at our website. that's bbc.com/sport. but from me, tulsen tollett, and the rest of the team, that's your tuesday sport briefing. canada's announced a ban on the single—use plastics that are most harmful to the environment and the world's oceans. prime ministerjustin trudeau says the ban on items such as straws, cutlery, bags, and cotton buds will come into effect in two years' time. the european union made a similar decision in march. tim allman reports. floating almost serenely beneath the waves, this isn't a jellyfish — this is a plastic bag. and here, fish swimming through discarded netting, more sea life endangered by man—made pollution. each year, millions of tons of plastic are dumped into the world's oceans, but one by one, countries say they will do something about it.

plastic pollution is a global challenge. you have all heard the stories and seen the photos, and to be honest, as a dad, it is tough trying to explain this to my kids. canada alone thows away around 3 million tons of plastic waste each year. bags, straws, cutlery — things that do make life a little more convenient. but it seems people are willing to make sacrifices. if you see any pictures on the news or online of oceans of plastic and animals that are getting killed by eating it, whales, turtles et cetera, i think it is stupid to have a straw for five minutes for a latte or whatever and then it goes in the ocean. i mean, come on, give me a break.

canada and the european union have already made commitments to dramatically reduce plastic waste in the coming years, but there is still a long way to go to clean the earth's oceans. this is a story we know you are keenly aware of. many of you are taking action to try to amount —— try to reduce the amount of plastic you consume or what you do with your waste. we have heard from quite a few of you, thank you for getting in touch. one listen —— one reviewer says it would be good if we could make a plastic that starts to slowly break down in contact with saltwater. perhaps a good idea, but it still may be harmful in the sea, evenif it still may be harmful in the sea, even if it does break down. guy says it is easy to stop using single—use plastics if they stop producing them. we have one viewer from plastics if they stop producing them. we have one viewerfrom delhi who says, here we have tried to ban plastic bags, we have replaced them with paper bags but unfortunately

the plastic has come back again, so i believe it should be banned permanently. many are arguing it does take government policy to really change our behaviour. see you soon really change our behaviour. see you soon for the business briefing. monday brought about a month's worth of rainfall to some southern parts of rainfall to some southern parts of the uk. tuesday is going to bring yet more rain but it looks as though the rainfall is going to be a bit further north, as far as today, tuesday, is concerned. in the forecast, here is the satellite image first of all. lots of clouds rolling around western parts of europe, we've seen thunderstorms in the near consonant, heavy rain here in the uk, and basically this vortex has formed in western parts of europe. it has been responsible for dragging the colder air from the north, going into france where it

has also been cold. northern spain not particularly warm. eastern europe central and eastern europe in the midst of the heatwave, with temperatures in excess of 30 degrees. in the early hours you can see where it is raining. many northern and central parts of the uk still getting rainfall. the south—west of parts of britain as well. wales, heavy rain, scotland and northern ireland, a very different story. by the end of the night the thinking is that the south—east will slowly start to dry out. they may even be some sunshine first thing in the morning. let's pick up on that forecast on tuesday. here is the weather front. it is not com pletely here is the weather front. it is not completely stationary, it is moving very slowly to the north so the anticipation is that we will get lots of rainfall around yorkshire, the pennines, the of england, and the pennines, the of england, and the south—west. to the north of that, in scotland and northern ireland, it is a case of sunny spells and some sunshine in the south—east and central and southern england, but here we could see some

thunderstorms developing. there could still be some big downpours on the way for tuesday. the heaviest of the way for tuesday. the heaviest of the rain will be a bit further north and then on wednesday, it is still raining across parts of northern england, wales, and they will be yet more heavy showers drifting and swinging in through the south on wednesday. a very unsettled spell on the way for much of the week. beyond that, wednesday to thursday, but vortex i mentioned, otherwise low pressure is still here. it has gone across the uk. in summery, it is a case of heavy rain at times. it will be cool, and at times windy. goodbye.

this is the business briefing, i'm sally bundock. game on. we visit the world's largest gaming expo, and get the lowdown on why the industry is moving towards streaming. everyone is crazy about going inside to see what is the next thing. we wa nt to to see what is the next thing. we want to be the first one in line to see what is in the future and what is coming out. and pakistan's government unveils a tough budget, in the hope of securing a large loan from the international monetary fund. and on the markets: the focus once again is on the trade

spat between the us and china, with new threats from the
