storm barry makes landfall in the american state of louisiana, where there are warnings of life—threatening floods. the subway at a standstill and people stuck in lifts, as a power cut hits manhattan for five hours. and coming up... we'll be looking at the this morning's papers with rosamund urwin from the sunday times and robert fox from the evening standard. that's at 9:40am. good morning and welcome to bbc news. the mail on sunday has published more leaked messages sent by britain's former ambassador to the united states. in one of them, sir kim darroch accuses president trump of "diplomatic vandalism" over his decision to abandon the nuclear deal with iran.

the documents were published, despite a warning from police to the media not to print the leaked material. both conservative leadership contenders have defended the rights of the press to publish the document. jeremy hunt described it as a vital part of british democracy. we have to remember that the official secrets act is there for a reason, and it is the police‘s job to decide if a criminal act has been committed, but at the same time, not forget what is precious about our country, which is that we have one of the most vibrant and free media in the world, and this is a country that has always been known for standing up for democratic values, so we have to make sure that we defend the right ofjournalists to publish leaks when they are in the national interest, and when national security hasn't been compromised.

i'm joined by our political correspondent helena wilkinson. took us through these revelations. a week on. the mailfrom kim darroch back to london where he described donald trump as inept. we now have these fresh revelations in the mail on sunday. they focus, billy, on the iran nuclear deal and what we have heard is that sir kim darroch has described trump a's determination, last year, to abandon the nuclear deal with iran as it an act of diplomatic vandalism. there relates toa diplomatic vandalism. there relates to a trip on borisjohnson took in may of last year. he was with sir kim darroch and the aim of that trip was to try to get donald trump not to abandon the nuclear deal. under that deal, iran had agreed to limit the nuclear activities in return for

a lifting of economic sanctions. they were not able to successfully persuade donald trump and sir kim reportedly reports back to london that mr trump has mike administration has set up an act of the asthmatic —— an act of diplomatic vandalism to spite his predecessor barack diplomatic vandalism to spite his predecessor ba rack obama. diplomatic vandalism to spite his predecessor barack obama. in these m essa 9 es predecessor barack obama. in these messages it also highlights there we re messages it also highlights there were various splits amongst presidential advisers and the weight has apparently, according to these messages, did not have day—to—day strategy on how to deal with the aftermath of this. —— at the white house. these memos were published despite a warning from the police. that morning itself has become a hot political issue now. yes, sir kim darroch resigning, many people would have thought that this issue would have thought that this issue would have died down now and gone away. we now have a criminal investigation into what has gone on and who was behind these alleged leaks. as you

rightly say a furious row about whether the paper was right to print it is on the one hand you have whether something is in the public interest or whether it interests a republic. the newspaper have said very strongly that the work they have published as any public interest and they were right to publish it. the assistant commissionerfrom the publish it. the assistant commissioner from the metropolitan police has warned journalists that they could be in breach and it could bea criminal they could be in breach and it could be a criminal act, if you like, if they do carry on and publish these alleged leaked documents. thank you very much indeed. let's talk more about the legality of this. we are joined from our salford newsroom by david banks, who is a media law consultant. could a paper like the mail on sunday be committing a criminal offence by publishing this kind of

material? it is theoretically possible that they could. receiving material that has been a close in breach of the official secrets act and then publishing it yourself is and then publishing it yourself is an offence. but it would be extremely unusual for a prosecution to take place in the circumstances. in any such case in the past, there has been a pursuit of the liquor by the investigating authorities. but they have not gone after newspapers are broadcasters, journalists who are broadcasters, journalists who are publishing something they regard to be in the public interest. —— in the past there has been a pursuit of the past there has been a pursuit of the leaker. if the material is in breach of the official to secrets act —— official breach of the official to secrets act — — official secrets breach of the official to secrets act —— official secrets act and if it has done damage and publication has done damage, then you have committed an offence under the official secrets act. that is the key question. the crown prosecution service, if they got as far as the

police sending a file to them for prosecution of a journalist and newspaper, they would then have to decide, is it any public interest to prosecute this newspaper. and that would be a very tough question for them. to decide, for the first time, as farasi them. to decide, for the first time, as far as i can recall, for the first time to use this lot to prosecute a newspaper in this way. it would be extraordinary. what is covered by the official secrets act? because these are memos with opinions about the weight has, opinions about the weight has, opinions about the weight has, opinions about donald trump. i is actually state secrets? —— about the white house. when we think of state street kids i think we think of issues of defence the new submarine oi’ issues of defence the new submarine or something like that. —— when we think of state secrets. diplomatic communications can be covered by the official secrets act but it covers a wide range of material, from things about the defence of the realm and threats to us as a nation, turn ambassadors nation of the political leader of the country that he or she

happens to be in. —— two the opinion of the ambassador. doctor mike damaging and embarrassing are two different things. with this warning from scotland yard, potentially that a newspaper would be in breach of the law by publishing this material. do you think that they have overstepped the mark? there was a big political reaction to that. i have never seen a morning like this in circumstances like this. i can only think they have. the strange nature of it is indicated by the reaction there has been across the board from newspapers, who are usually pretty cut—throat competitors. but if you look at them today and a statement from political leaders as well. i think that the met called it wrong on this issue. thank you very much for being with

us. a man's been changed with the murder of a heavily pregnant woman and the manslaughter of her baby in south london. 26—year—old kelly mary fauvrelle was stabbed to death at her home in croydon last month. her son riley was delivered by paramedics but died days later in hospital. two whistle—blowers featured in a bbc panorama investigation into anti—semitism in the labour party have said they now plan to sue the party for defamation. the programme — shown last wednesday — included claims that senior figures including jeremy corbyn‘s communications chief and his general secretary, had interfered in anti—semitism investigations. labour responded after the programme by saying the allegations came from "disaffected former officials" opposed to mr corbyn‘s leadership. the whistle—blowers allege that labour painted them as people who had falsely made malicious representations. just one match away from making history, england take on new zealand in the men's cricket world cup final

at lord's later today. it's their first final since 1992, and neither team has ever won the trophy. mike bushell reports. come on over! it's the biggest game so far for england, come on! a cricket home world cup comes along once in a generation and the england squad certainly have not let this opportunity slip through theirfingers. after crashing out of the group stages four years ago, 27 years have passed since england were last in a world cup final. and they now stand on the brink of winning one of sport's top honours for the very first time. it means a huge amount to me and to everybody in the changing room. it's a culmination of four years of hard work, dedication, a lot of planning and it presents a huge opportunity to go and try and win a world cup.

this tournament has seen a good—humoured age—old rivalries at play, selling out stadiums up and down the uk and never short of excited fans. get in! england came into the tournament as the one's to beat, but their progress to the final has not been straightforward. england came into the tournament as the one's to beat, but their progress to the final has not been straightforward. back to back defeats to sri lanka and australia in the group phase left them on the verge of elimination. but then came vital wins against india and new zealand before their semifinal triumph over australia at edgbaston. it's the best sporting live day of my life. fantastic! amazing! we never beat australia like that. # we're just a small island nation! new zealand are now gearing up for their second consecutive world cup final, hoping luck will be on their side at this time around. it's just a great occasion to be part of and i know the guys are really excited by the opportunity to go out and try and play with that freedom that, when we do, gives us the best chance. and for the first time in 11! years, england will play a home international on terrestrial tv after rights—holders sky agreed to share the coverage with channel 4, meaning fans not lucky enough to be inside a packed

out lord's won't miss out on any of the action. mike bushell, bbc news at lord's. the chancellor of the exchequer has said that... the uk will not be able to control key elements of a no—deal brexit, should we leave the eu without a deal. he was speaking to the bbc panorama programme with just days before he is expected to leave. the chancellor has said the eu will control most of the process if the uk leaves without a deal later this year. he's warning that france will be able to dial up friction at the border if the country chooses. millions of people are braced for potentially life—threatening flooding after tropical storm barry made landfall in the us state of louisiana. more than 100,000 households are already without power and flooding is expected to be most severe in areas southwest

of new orleans. and flooding is expected to be most severe in areas south—west of new orleans. our correspondent sophie long reports. coastal towns were battered by winds of up to 70 miles an hour. there was flooding in low—lying areas and whole communities were left without power. now, the storm is moving slowly north through the state of louisiana. barry may have been downgraded from a category one hurricane to a tropical storm almost as soon as it made landfall but people here in new orleans are still concerned. this is one reason why. the mississippi river has been swollen to flood levels for many months and now forecasters are predicting there could be a huge downpour of rain in the next 48 hours. there is so much water with the storm, it will come north. and where some of these rain bands sit, they have the potential to produce a foot or more of rain. that is really what we are watching right now. people here originally heeded warnings to shelter in their homes

but as they started to return to the streets, the city's mayor warned they were not out of the woods yet. while the storm surge risk on the mississippi river has passed, the primary risk continues to remain. heavy rains for new orleans. the levy system that protects the city from major flooding has so far stood up to the storm's force. but there is concern that heavy rain could still overwhelm the city's antiquated drainage system and flash flood warnings have now been extended to this evening. let's ta ke let's take you to paris because it is bastille day and at the commemorations and celebrations are under way there. with the particularly spectacular parade. president macron there. just over

4000 members of the armed forces are taking place in the parade and expected to join president macron, the german chancellor angela merkel and theresa may. they will be watching it on the champs—elysees. the storming of the fortress... fireworks displays. all fire stations will open their doors to the public. that has the scene in paris on bastille day. 9:15am is the time. they had... the headlines on bbc news... more leaked memos from britain's former ambassador to washington suggest donald trump abandoned the iran nuclear deal in order to spite barack obama. police charge a man with the murder of kelly mary fauvrelle —

the 26—year—old who was 8 months pregnant when she was fatally stabbed at home. england's cricketers prepare for the biggest game of their lives — as they face new zealand in the world cup final. schools and hospitals in england and wales could be held accountable if they fail to spot signs of violent crime among young people. that's according to plans due to be announced by the government this week. public bodies would have a legal duty to work together to report concerns about children at risk. here's our home affair‘s correspondent dominic casciani. a community programme putting football at the heart of saving lives. the london—wide premier league kicks initiative has worked with hundreds of young people at risk of falling into a life of crime. now, the home secretary sajid javid wants to go ahead with a new public health duty on public health bodies that will put them all at the centre of spotting serious violence that has blighted cities across the country.

the proposed duty will cover police, councils, health bodies, schools and colleges. it will compel them to share intelligence of youths at risk of serious violence. ministers hope the legal duty will mean professionals, such as mentors, can intervene earlier to turn around more young lives before it's too late. but it is not without controversy. when the idea was first floated in april, teachers and nurses responded with both dismay and scepticism. they warned that the threat of legal sanctions against them for not spotting the warning signs would lead to them overwhelming the system with alerts out of an abundance of caution. the final proposals, to be unveiled this week, have been amended so that institutions such as schools, rather than individual professionals, will be monitored for how well they are doing in identifying vulnerable young people. that change has been welcomed, but the plan will still need parliamentary time to become a reality and critics say it needs to be backed by a massive investment

in youth workers and other experts who have been cut over the last decade. dominic casciani, bbc news. power's been restored to all of new york city after an outage lasting several hours. the difficulties started with a fire in an electrical transformer in manhattan — the most densely populated of the city's five boroughs. street lights and traffic lights were put out of action and the subway system was affected. the bbc‘s tim allman reports. life is certainly never dull in new york city. the upper west side of manhattan, members of the public having to direct cars because the traffic lights weren't working. and this was the new york subway, much of it cast into darkness. the trains providing the only illumination. these photographs were taken by one

manhattan resident who told the bbc what it was like when the lights went out. it is a very eerie because half of the city is essentially black and the other half to the south was essentially fine. it was a strange place to be from my vantage point. one part of town that was affected was broadway with many shows are having to be cancelled. jennifer lopez tweeted: "devastated and heartbroken that i can't perform for all of you tonight. we will make this up to you, i promise". irony of ironies, all this happened 42 years to the day after the famous new york black out of 1977. that was on a much larger scale and lasted nearly two days. but a reminder of how things can go — very wrong indeed. but a reminder of how things can go - very wrong indeed. this could have been much worse. when you're talking about a city like new york with a significant piece of the city suffering a blackout, that could be a very chaotic situation. we saw the

exact opposite. some traffic problems continued into the night, as work went on to restore power to all new yorkers. times square was unaffected, still lit up like a christmas tree. new york is always defiant. tim allman, bbc news. most of us are familiar with drones that fly.....but could aquatic drones be part of the solution to tackling water pollution? remote controlled machines, fitted with sensors that measure the health of the water, are being tested in scotland's canals. it's hoped that one day they might even be used to clean the water. laura goodwin reports. it looks like a small aquatic batmobile and to be fair, this water drone does have a superhero potential. it's the latest technology in the fight against water pollution. dale invented the bot to travel along the surfaces of rivers and canals to monitor water quality.

now it's being tested on some of scotland's busiest waterways. all these parameters measure different aspects of the water. we have dissolved oxygen, ph, electro—conductivity, orp, temperature and dissolved solids. when we bring all these parameters together we can get a bigger picture of what the activity is like within the water. can you tell me what these bits are for? yes. these are actually for feeding swans. i'd read a bit about people feeding swans the wrong type of food so i thought why not go the extra mile and feed them while we are out there? the drone collects multiple samples as it travels across the water and then can relay the data. the oxygen levels are looking good because we've got lots of amazing fish in the canal. proves the point. fish are great. oxygen levels show that's possible. what's great about it, you don'tjust have one person with a small bucket collecting

individual samples, we can sample continuously along a long stretch of the canal and get much more information, much more quickly and cheaply. it matches very nicely with other work that we are doing on the smart canal in glasgow which is looking at how we can understand quantities of water as well as quality and control things like flooding in the glasgow area so it's hugely innovative and it's exciting because all of these things come together to protect us with the climate emergency which is coming on to usjust now. at the moment the drone is using sensors underneath the water to measure things like oxygen level and ph that gives an indication of the health of the water. but, ultimately, the aim might be to create a drone that not only measures the quality of water, but also improves it as it goes. cleanliness of water is something that's really interesting when you start looking at drones. we'd like to know if it's possible to be able to develop a small water treatment plant. with a larger drone. with summer here are canals and lochs our canals and lochs become all the more attractive

with people keen to explore scotland's iconic waterways. perhaps a small but mighty fleet of water drones could soon be central to ensuring they stay that way. this week marks 50 years since man first landed on the moon, and if it wasn't for a ground—breaking british invention, it might never have happened. a scientist at cambridge university developed the fuel cell which provided the electricity to power part of the apollo 11 space craft. here's our science correspondent richard westcott. tucked away on board apollo 11, just behind neil armstrong is a small device without which president nixon said they would not have reached the moon. going to go for a landing... and here is one part of it. it does not look much. this is a classic example of an object that looks so simple on the outside, incredibly complex on the inside and actually change the course of history.

on the outside, incredibly complex on the inside and actually changed the course of history. it's an electrode from a bacon fuel cell. a prototype because the original was left in space. as we can see from the old manual, 30 of those discs combined into a cell that provided the electricity for apollo 11. it consumes hydrogen and oxygen to water and produces electrical energy. he makes it sound simple but the inventor cracked a huge — —— the inventor tom bacon cracked a huge scientific problem scientific problem — to turn the theory of a fuel cell into a practical working device. it seems to me that this is almost as revolutionary as the discovery of steam traction. would you agree? i would like to think so but remember, i am an enthusiast perhaps you should have that confirmed by someone else. professorjohn davidson knew tom bacon well. he was always terribly polite. he would ask you what your interests were and if they had any bearing

on the fuel cell he was deeply interested. but if they did not, he switched off. but why was the fuel cell quite so good? and how does it work? new students in bacon's old cambridge department showed me. pretend you're on tv, funnily enough, tell the people what you have. we have a small part of a soapy water and a balloon filled with hydrogen gas. what we will do is generate a layer of hydrogen bubbles on top of the water and then we will ignite it and you shall see a small—scale explosion. the cells used hydrogen and oxygen that were already on board apollo as rocket fuel. when combined, they create energy. which can generate electricity. even better, the only byproduct was water. which the crew drank. it is safer, lighter,

it is smaller, quieter and, above all, more efficient. the bacon fuel cell. the small british invention that made the moon landings possible. it's been called the "poldark—factor". the bbc drama, which is based in cornwall, has become such a successful global brand that it's attracting tourists from all over the world. ahead of the new series, we caught up with a group of american fans who were visiting some of the locations used in the show. eleanor parkinson reports. what are you up to? daydreaming. the drama of poldark has captured the hearts of millions across the uk. there's the romance, the scenery, its swashbuckling hero... oh, and did i mention the romance?

and the drama is notjust confined to cornwall because behind me are a group from virginia in america and they are part of a growing band of global fans of poldark. the american fans are on a tour of just some of the locations that provided the tv series with its stunning backdrop and they haven't been left disappointed. i knew it would be beautiful but, honestly, it's breathtaking. every time you turn a corner, it's so lovely. you're very fortunate. i've always done a lot of reading about england and cornwall was a place that captured my imagination when i was just a young girl and so, being able to see that visually was just tremendous. i love it. ijust love it. and now you are here, is up to expectations? she sighs. i think itjust surpasses expectations. it is just staggeringly beautiful. the history... i knew nothing about this area. i love the fact that poldark himself, ross poldark, is pulling for the common man, even though

he is an aristocrat. and the george character is such an incredible nemesis. and all of the casting is so well done. after the mining heritage, it is back on the bus. next stop — the beach. the beach is a favourite spot for ross and demelza. they can walk windswept, barefoot and indulge in a bit of that romance. today there were just a few more people on the beach but they were still able to walk in the footsteps of their favourite characters and get their feet wet. just around the cliffside which you can't see until the tide is out, is the beach where they filmed the shipwreck scenes. poldark is now a household name in many countries all over the world. and those making this poldark pilgrimage are also boosting the county's tourism industry. maybe something this brooding miner and adventurer didn't foresee.

eleanor parkinson, bbc news, cornwall. now it's time for a look at the weather with helen willetts. eastern parts of england woke up to some charity rain this morning and thatis some charity rain this morning and that is heading its way southwards are now quite quickly. —— showery rain. it will be a dry sunday. we have already had some sunshine in western areas, but as i say, a cross at the london area we have the early rain at the cricket. it has an improving picture by hand that band of showers —— improving. we have a sunny skies coming through are certainly more sunshine than when we started the day. the best of the sunshine will continue to be further west, we will see the higher temperature here. there's quite a keen breeze coming onshore across east anglia and the south—east of england. temptingly feel of the day. leiter went further west and it

could trigger the odd shower over the hills in the afternoon. temperatures up across northern ireland, scotland and a bit cooler near the north sea coast. hello. this is bbc news with ben brown. the headlines... more leaked memos from the uk's former ambassador to washington suggest president trump abandoned the iran nuclear deal in order to spite barack obama. a man is charged with the murder of kelly mary fauvrelle — the 26—year—old who was eight months pregnant when she was fatally stabbed at home. the chancellor philip hammond warns that the uk will not be able to control key elements of a no—deal brexit. storm barry makes landfall in the us. state of louisiana, where there are warnings of life—threatening floods.
