welcome to bbc news, i'm mike embley. our top stories: in the us, the house intelligence committee releases its impeachment inquiry report, accusing president trump of putting his interests ahead of america's. he was willing to sacrifice the national security of the united states in order to get what he wanted. the two men who founded google, larry page and sergey brin, are stepping aside from running its parent company. the tech billionaire elon musk claims in court that he did not literally call a british cave diver a paedophile. and the winner is — all of them. all four artists shortlisted for the turner prize declare themselves a collective and the prestigious prize is shared between them.

with president trump in london at an international summit, his opponents in washington have moved against him, with the next phase of the impeachment inquiry that has the potential to remove him from office. he has described it as an "unpatriotic witch—hunt", a "one—sided sham." but the latest report from the house of representatives, which is dominated by the democrats, claims there is "overwhelming" evidence that mr trump placed personal political interests "above the national interests of the united states", pressuring a foreign government to interfere on his behalf in next year's presidential election. there is flash photography in this report from peter bowes. page after page, the case to impeach donald trump. overwhelming evidence of misconduct and obstruction, according to the house intelligence committee, which is controlled by the democrats.

after hearing from more than a dozen witnesses, the panel concluded that mr trump solicited the interference of a foreign government, ukraine, to benefit his re—election. he put personal political interests ahead of the national interest. this is the result of a president who believes he is beyond indictment, beyond impeachment, beyond any form of accountability and indeed, above the law. and that is a very dangerous thing for this country, to have an unethical president who believes they are above the law. the white house slammed the impeachment enquiry as a "one—sided sham", which had "utterly failed to produce any evidence of wrongdoing" by president trump. but the investigation goes on, moving to the housejudiciary committee, which will consider specific charges, the articles of impeachment, against the president. again, the democrats are in control, and if, as expected, the full house of representatives votes in favour of impeachment, a trial could take place as early as next month in the senate,

where the republicans are in charge. it's all in the house at the moment. and as i've said over and over again, if the house does in fact act, then the senate will be in business with an impeachment trial. donald trump has repeated his view that the impeachment enquiry is a "hoax", being used by the democrats for political gain. but like it or not, and with the president still out of the country, the process is moving quickly. peter bowes, bbc news. a big move in one of the world's most powerful tech outfits, the two men who founded google — larry page and sergey brin — have announced they are stepping down from running its parent company. they will leave their roles as ceo and president of alphabet but will remain on the company's board, still controlling 51% of voting rights. our north america technology correspondent, dave lee, has more. this move represents the most significant shake—up of leadership

at google since its inception. the first time the dynamic duo of sergey brin and larry page — a legendary silicon valley partnership — won't hold important management roles in the company they founded back in 1998. in reality, though, that has been the case for some time. the public face of google has been its current ceo, sundar pichai. but tuesday's announcement makes it absolutely clear mr page and mr brin aren't running the company anymore. however, while the pair are willing to sing managing duties it, won't mean giving up their ultimate power. between them they control 51% of voting rights on alphabet‘s board. this won't change. they liken their role to being proud parents to the company, looking on with close interest and care. it means, should they feel the need, they can

override any decision mr pichai makes with little more than a parental "because we said so." dave lee, bbc news in san francisco. let's get some of the day's other news: china's foreign ministry has expressed "strong indignation" at the passing, by the us house of representatives, of a bill demanding sanctions on senior chinese officials for the repression and detention of hundreds of thousands of uighur muslims in xinjiang. the bill passed overwhelmingly and now goes to the senate for debate. at least three people have been killed in a powerful typhoon which has lashed the philippines, with winds gusting up to 200 kilometres an hour. typhoon kammuri passed just south of the capital, manila. but the international airport there remains closed. officials say the evacuation of around 225,000 people prevented greater loss of life. the president of the european commission, jean—claude juncker, has officially handed over to his successor ursula von der leyen at a ceremony in brussels. the former prime minister of luxembourg was emotional as he made a short speech. his five—year term was marked by some stiff tests for the eu,

including the migrant crisis, internal tensions and of course, brexit. nasa says the wreckage of india's vikram lunar lander has been identified, three months after it crashed onto the surface of the moon. it was thanks in part to an indian space enthusiast, an it engineer who spotted it when he ran side—by—side comparison images on two laptops. the us space agency had released satellite images and asked people to search for it. australia has controversially repealed a law which allowed sick refugees held offshore to be treated in the country. the ‘medevac law‘ has been criticised by the government as compromising australia's borders. the prime minister believed it posed a threat to national security and has won a vote to scrap it. let's get more now from our sydney correspondent shaimaa khalil.

this is going to be controversial? extremely controversial. this medevac law has basically brought to the fore that extremely contentious political issue between a government and the opposition, the government is unrelenting in its policies to deter asylum seekers who are coming to australia by boat by sending them to australia by boat by sending them to offshore detention centres. there have always been doctors complaining and reports saying there have been medical and mental health crises on these islands, and island, children as children as young as 11 committing suicide. that is really what prompted a public outrage that resulted in the medevac law is essentially allowing medicals and doctors to transfer sick refugees —— medicos and doctors to transfer sick refugees for treatment in mainland australia. that has always been seen by the government as a security loophole, as some of them put it, to bring people into australia via the back doors. so even though we're

talking about very vulnerable individuals who need treatment that is not available in these areas, here it is a very political issue about a government that is still very insistent that it is deterring refugees to protect australian borders. and for as long as the bill has been in force, i think it was what, 135 refugees brought to the mainland for treatment. is that it? is that the end of their chances for treatment? it looks like it. got morrison, the prime minister was speaking to the press just a few minutes ago before i spoke to one hour. he seems pleased with the result. it's controversial because it seemed to hinge on the vote of one independent mp sided with the government and said once overall, this repeal is shutting the door, as he put it. a door that labour, the opposition party has been trying to open. 135 australian mac refugees came to australia for treatment, but 110w came to australia for treatment, but now this has been repealed, nobody has the chance to apply for

treatment because they basically don't have the right to anymore. -- 135 refugees. thank you for that. divisions between nato leaders have been exposed, with president trump accusing france's president macron of being "nasty" and "disrespectful", for describing nato as "brain—dead." mr macron defended his comments and highlighted differences with turkey, which is threatening to derail efforts to set up a new missile defence system. this report from our diplomatic correspondent james robbins contains some flashing images. buckingham palace and a birthday party for nato leaders to celebrate their military alliance and 70 years success keeping the peace through collective defence. everyone on best behaviour for the queen, but nato is a family currently at war with itself. france's president macron has been strongly critical of donald trump's isolationist role and called nato strategically brain—dead. today he stood by those remarks, even after mr trump

rebuked him publicly. when you make a statement like that, that is a very, very nasty statement to make to, including them, to essentially 28 countries. i think that, you know, they have a very high unemployment rate in france. france is not doing well economically at all. in fact, the alliance faces another far larger threat to unity — the military action by nato member, turkey, inside northern syria. turkey's president erdogan is enraged nato isn't100% supportive of his fight against kurdish troops that he brands terrorists. but president macron completely rejects the turkish position. when i look at turkey, they now are fighting against those who fought with us, shoulder to shoulder, against isis. 70 years ago when nato was established it all felt

so much simpler. the american—led alliance faced a single enemy, the soviet union underjosef stalin. it was soviet communism which eventually collapsed. nato survived, but now struggles to agree its future role. nato is the most successful alliance in history, because we have been able to change when the world is changing. that is exactly what we're doing again, and the fact is that we're doing more together in this alliance now that we've done for many decades. but that sounds far too upbeat to those leaders who think the alliance has lost its way and needs to face up to developing threats. so, what are some of those future threats nato has to face? well, still from russia and there's talk now of china, too, not an adversary, nato insists, but a worry, nevertheless.

and there is concern about possible future cyber attacks on satellites in space. how would nato react to that? president trump is now claiming success, pushing other states to increase their nato spending and so reduce america's 70% share. but other splits over the way ahead won't be resolved in a few hours of formal talks tomorrow. james robbins, bbc news, buckingham palace. stay with us on bbc news. still to come: empowering communities in africa, the simple device that delivers the data to fight pollution. it's quite clear that the worst victims of this disaster are the poor people living in the slums which have sprung up around the factory. i am feeling so helpless, that the childrens are dying in front of me and i can't do anything. charles manson is the mystical

leader of the hippie cult suspected of killing sharon tate and at least six other people in los angeles. at 11am this morning, just half a metre of rock separated britain from continental europe. it took the drills just a few moments to cut through the final obstacle. then philippe cozette, a minerfrom calais, was shaking hands and exchanging flags with robert fagg, his opposite number from dover. this is bbc news. the latest headlines: the us house intelligence committee has released its impeachment inquiry report, which accuses president trump of putting personal gain ahead of the american national interest. the white house says there is no

evidence of any wrongdoing. the co—founders of google, larry page and sergey brin, are stepping aside from running the company they built into a giant of the digital economy. elon musk, the billionaire founder of electric car company tesla, has told a court he did not literally call a british cave diver a paedophile. the tech billionaire, seen here, told the defamation trialjury he was simply defending himself from unprovoked insults. the spat with vernon unsworth took place as the diver was helping rescue young soccer players trapped in a cave in thailand. sophie long has more. well, the first opening statement came from vernon unsworth‘s lawyer, the man leading his legal team. and he told the court all about that rescue that you talk about, the rescue that really captured the world's attention, and how that despite that, when the world was celebrating, vernon unsworth had gone on television and given an interview in which he was asked about elon musk‘s attempt to help,

the submarine, the mini—submarine he offered, and how he had dismissed it in that television interview as a pr stunt. he then talked about the tweets, the succession of tweets that came from elon musk later, and he said that the particular tweet in question in which he called vernon unsworth "pedo guy" was very damaging. he talked about how he felt the shame of being accused of being a paedophile, at what should have been one of the proudest moments of his life. we then heard the lawyer leading the defence, elon musk‘s lawyer. he gave a very different picture of the same series of events. he said that this is a case about an argument between two men trading insults, and he said that it was vernon unsworth who went on television first, and he made the first insult. and he said it was not an allegation of a crime, it was that — an insult. he also said that that tweet was deleted. he said it was a joking, deleted, apologised—for tweet. there was no damage caused. he went on to say that, instead of damage caused

to his life, that was set out by vernon unsworth‘s lawyers, actually it had expanded his social media profile, and he now needed an agent to deal with all the requests. so two different accounts of the events that led up to this case. the california senator kamala harris is ending her campaign for the democratic party's presidential nomination. the former prosecutor says she will keep fighting for people whose voices are ignored. originally seen as a frontrunner, she has recently been polling in single digits and has struggled forfunding. the family of the man who carried out last week's attack near london bridge say they are shocked and saddened by what happened, and that they totally condemn his actions. usman khan killed jack merritt and saskia jones and injured three others before being shot dead by police. in a short statement, his family expressed condolences to the families of the victims. a new study says the growth in global co2 emissions has slowed

this year, largely because of an unexpected drop in the use of coal. the report, issued at the climate change conference in madrid, says the overall rise in carbon dioxide levels will be 0.6% this year, down from 2.1% in 2018, but experts are warning that the drop in coal is offset by the strong growth in natural gas and oil consumption. one of the consequences of carbon emissions is air pollution. it is thought to kill around 7 million people across the world every year, according to the world health organization. one group of african scientists is trying to alert people to the problem with a low—cost sensor that allows citizens to monitor and record the air quality in their community. solomon serwanjja reports from nairobi. tina and her one—year—old daughter clarissa live next to a steel mill in a pollution hotspot on the edge of nairobi. the white, powdery ash from the mill has to be washed away every day.

the particles and some other black smoke that normally comes out, that is the worst thing. when you breathe those particles, it's so painful. at this local clinic, the number of cases of pneumonia, asthma and chest infections has doubled in the last 12 months. the world health organization recognises air pollution as one of the causes. cecilia can hardly breathe, and this woman's lung capacity is not what it should be. there are nearly 750,000 people living in this community, and many of them are struggling to breathe because of the air quality. there is a team of african scientists who have come up with ways of measuring the air quality here, and they think that it is a step forward in finding a solution to this problem.

these low—cost air pollution sensors are easy to install. they detect and record the amount of dangerous small particles in the air. that data is then transmitted to a website, where it can be accessed by anyone for free. our data is accurate, which means anyone in any city across any african country will be able to use it, deploy it, and get real—time local data for their neighbourhoods, that they can use to petition governments to solve problems that they face around air pollution. that is what the community living next to this asphalt factory did after they started having breathing problems. they installed sensors in their homes. our campaign got the attention of the media and the government agencies that were ignoring us before. the director of the environment agency came over and instructed them, the factory, to shut down, and only open after they

complied with the laws. another part of town, rashida and nazir, who like tina live near a steel mill, are still mourning their two—year—old daughter who died in april. the cause of death was a respiratory disease, and the doctors say it could be caused by air pollution. now, they are worried about their surviving son. look at all these inhalers. i have to use this. the doctors are wondering. you know, this is too much for him. he is coughing. when he coughs, he coughs for a whole week. nazir believes that the data from the sensors in his community will help his campaign for clean air. data will not lie. sensors will not lie. it's very clear. all you need to do is use that, and you will get the answers you need. that's all we need. their hope is that this technology

will empower communities like tina and clarissa's to fight for their right to clean air. the south korean singer and actor cha in—ha has been found dead in his home. he is the third k—pop star to die injust three months. no details have been released about how the 27—year—old died. cha's death comes less than ten days after k—pop singer goo hara was found dead in her home. a british veteran who escaped the siege of dunkirk during the second world war by paddling out to sea on a door has died at the age of 101. les rutherford became trapped during the evacuation of the port injune1940. he and a fellow soldier used the door which had been blown off a garden shed to paddle out to sea, where they were picked up by a french trawler. he was given a glass of rum and returned to england wearing only a blanket and socks. he was described as a wonderful man

who will be sorely missed. the winner of this year's turner prize has been announced at a ceremony here in london — or that should be winners, because for the first time ever, the world—famous art prize was awarded jointly to all those artists who had been nominated. rich preston has the story. the british seaside town of margate was the backdrop, and the traditional fairground park dreamland. now in its 35th year, the turner prize is known for its shock value. damien hirst‘s nomination in 1982 of a tiger shark in formaldehyde was one of the decade's most controversial pieces of art. in 1999, tracey emin‘s work my bed caused a storm, though it didn't actually win. but this latest shock wasn't anything to do with the art itself. here's something quite extraordinary. at a time of political division in britain and conflict in much

of the world, the artists wanted to use the occasion of the turner prize to make a strong statement of community and solidarity, and have formed themselves into a collective. applause. the four nominees wrote to thejudges explaining that their art is about social and political issues. lawrence abu hamdan‘s work recreates the noises inside a syrian prison, oscar murillo's is a congregation of human effigies, while tai shani's is described as a feminist fantasy beyond patriarchal limits, and helen cammock produced a film commemorating the role of women in the northern irish troubles. we each work with specific issues. we're each dealing with things

we feel passionately about, but it doesn't mean that those things, we see them in separation from each other. for us, it was important to use this platform in a specific political momentm and kind of do something that would go beyond just the normal thing that happens in this prize, really. in their letter to judges, the nominees said it would feel problematic to be pitted against one another, asking if, at a time of so much division, they could instead be considered as one. the judges unanimously agreed. and, staying with the subject of art, a malaysian minister has called a tattoo exhibition obscene and ordered an investigation after pictures of half—naked men and women went viral. the ministerfor tourism, arts and culture said that, while a permit was issued, there was no green light for any form of nudity at the event. around 60% of malaysia's 32 million people are muslim, and critics say the country has been moving towards more religious conservatism.

and finally, here is proof that almost anything is possible when it comes to photography, with a bit of patience. these 17 cats and dogs are all owned by kathy smith, from corwen in wales, and she says it took her several days to get them all lined up in one go for this portrait. a reminder of our top story: the democrat—led us house intelligence committee has released a report setting out its case for impeaching president trump, accusing him of a sweeping abuse of power for personal gain. it accuses mr trump of obstructing justice and congress and soliciting the interference of a foreign government, ukraine, to help his re—election next year. mr trump denies the accusations and regards the impeachment process as a democratic witch—hunt. and you can get in touch with me

and most of the team on twitter. hello there. we've got quite a mixture of weather coming our way for wednesday. now, the satellite picture shows a stripe of cloud approaching the west. this is a weather front that's going to be bringing us some rain. further east, though, we're under the influence of high pressure across much of england and wales, so the skies relatively clearer. now, if you're heading outside over the next few hours, we've got cloud and rain encroaching across western scotland and northern ireland. further south and eastwards across england and wales, there are some patches of cloud, but we've also got some clear spells. so contrasts in temperatures — it's mildest towards the north—west of the uk. with the clearer skies across england and wales, it's cold, and indeed, cold enough for some patches of frost. could even be the odd fog patch to start the day

on wednesday, as well. for many, though, it's a bright start across england and wales, eastern areas of scotland. the rain in the north—west will continue slowly pushing its way eastwards, reaching parts of northern england and north wales through the course of the afternoon. still bright to the south and east, but it's chilly still. highs of around 6—8. the mildest weather towards the north—west, with blustery showers following into western scotland, and some fairly gusty winds too. then, through thursday and friday, we're going to see weather fronts really target western scotland, bringing large amounts of rain here. now, we could see around 70—80 mm, maybe more than that over the high ground. that's enough to cause some flooding impacts, but it's not the only place that will see rain. on thursday, we'll also see some wet weather pushing in across northern ireland. the rain getting into northern england and north wales, too. further south and eastwards, probably a bit more cloud around, but it should be bright enough. it's turning milder as south—westerly winds spread in across more of the country. high for most between 9—12 degrees. what follows thursday night will be a very mild night. now, that might come as something of a surprise, especially when you consider recent

nights have seen some very sharp frosts. as we head into friday morning, these are the kind of temperatures —11—12 degrees. now, the reason it's so mild is it's cloudy, it's wet and it's windy, and initially we have the winds coming in from a south—westerly direction. later in the day we'll start to get north—westerly winds following in across the northern half of the country, and so temperatures will be dropping away. highs of seven degrees in stornoway. mild day for the midlands, east anglia and southern england, temperatures here around 12—13 degrees. now, the weekend looks like this. a ridge of high pressure to start things, but sunday sees a weather front move in across the uk. so saturday looks at the moment to be the better of the two days of the weekend, where it should be largely dry and bright. perhaps a bit of rain, though, getting in to northern ireland later in the day. sunday looks like it will turn more widely unsettled, with rain at times. that's your weather.
