veteran politician raila odinga gets one more chance to run for president. a last—minute decision to challenge the result of the presidential election paid off. the presidential election held on 8 august 2017 was not conducted in accordance with the constitution under the applicable law, rendering the declared result invalid, null and void. a shocking and rare judgment. the judges did not limit themselves to what happened on election day until the results were announced. rather they looked at the electoral process in its totality from voter registration to civic education as well as the campaigning and procurement of election materials. and so, in a sense, thisjudgment sets a strong precedent for election disputes globally and a high threshold for the conduct of elections. outside the court, celebrations erupted among opposition supporters. it's now back to the drawing board for presidential candidates. as much as i disagree with it, i respect it. i disagree with it, because, as i have said, millions of kenyans queued, made their choice, and six people have decided that they will go against the will of the people. the court directed the electoral commission to organise a fresh election. but the opposition says it has no confidence in the current commission. they have committed criminal acts. most of them actually belong injail. and therefore we are going to ask for prosecution, of all the electoral commission officers who have caused this monstrous crime against the people of kenya. the constitution states that a new election must be held within 60 days. for now, though, opposition supporters across the country are basking in the glory of the court victory. anne soy, bbc news, nairobi. more than moo people are now known to have died after the catastrophic flooding across several south asian countries. this year's monsoon season has been particularly heavy — affecting tens of millions of people in bangladesh, nepaland india. many who've been left homeless are now sleeping on roadsides and in makeshift shelters — short of food and clean drinking water. plumes of thick black smoke have again been rising from a chemical plant in texas, which was hit by severe flooding earlier this week. owners of the arkema plant, north—east of houston, had warned that its cooling systems had failed and that they would not be able to prevent it catching fire. the authorities have evacuated hundreds of homes nearby. president trump will head back to the storm—affected areas of texas on saturday. at his weekly address, he outlined his relief plans. at the request of governor abbott, i declared a major disaster in the state of texas to ensure that federal aid is available for state and local recovery efforts. i also approved a disaster declaration for louisiana. organisations like the red cross, the salvation army and faith—based organisations are actively assisting on the ground and they are doing a fantasticjob. a us—backed alliance of kurdish and arab fighters in syria says it now controls the old quarter of the islamic state group's main stronghold, raqqa. there's been no independent confirmation of the syrian democratic forces claim so far. it's thought that is still holds about 40% of raqqa, including its most strongly—defended neighbourhoods in the city centre. stay with us here on bbc news, still to come: the former england captain wayne rooney has been charged with drink driving. he's been released on bail. the british security company gas, has suspended nine workers at an immigration removal centre for allegedly abusing detainees. it follows a bbc investigation claiming officers "mocked and assaulted" people. it's alleged there was "widespread self—harm and attempted suicide" at the centre — which houses migrants who are about to be expelled. alison holt has more. brook house immigration removal centre sits a couple of hundred metres from the runway at gatwick airport. it's run by the global security firm gas. here, foreign national prisoners facing deportation at the end of their sentence are detained alongside asylum seekers, illegal migrants and those who've overstayed their visas. covert filming by the bbc‘s panorama programme shows a chaotic place awash with drugs with self harm commonplace amongst the men held there. there are officers doing their best, but the undercover investigation alleges some staff mock, abuse or even assault detainees. the incidents picked up by the hidden camera worn by another officer. callum tully has worked at brook house for two years. there's a culture of violence at brook house. when i started working there i was just... quite quickly became just disturbed by what i was seeing and hearing about. it's the latest scandal to hit gas. last year, another panorama investigation at medway secure training centre in kent led to allegations of the mistreatment of some teenagers held there. the company says it's waiting to see the brook house footage, but has suspended nine staff and put five others on restricted duties. my initial reaction is i'm absolutely disgusted by the alleged behaviour. it's totally unacceptable to me, to the organisation, to anybody else who would work in this kind of vocation. what does that tell you about the culture of brook house, but also the culture of gas? because culture comes from on high. my expectations are very clear. that we care for people, we look after people. on occasion we challenge people. and we do that in a way that is accepted, that is clearly laid down. it's understood an ex—gas officer who now works for the home office has also been suspended. the home office decides who is detained in centres like brook house. it says it condemns any actions that put the safety or dignity of detainees at risk. adding that gas needs to ensure there is a thorough investigation into the allegations. the company says it has alerted the police. the minister leading britain's effort to negotiate a new relationship with europe has met us business leaders to reassure them that a trade deal will be found. david davis refused to say whether oi’ david davis refused to say whether or not he had read that the eu was trying to blackmail britain into paying a divorce bill. the prime minister showing how it's done. at a meeting with the emperor of japan, a lesson in delicate diplomacy. but it seems her trade secretary hadn't got the memo. speaking injapan, he accused the eu of bullying the uk into agreeing a brexit divorce bill before it'll start negotiating any future trade relationship. we can't be blackmailed into paying a price on the first part. we think that we should begin discussions on the final settlement because that is good for business. it's no surprise there is a bit of rough and tumble at this stage in the talks and it's significant liam fox didn't repeat the word blackmail when asked exactly what he meant. a moment perhaps when frustration got the better of him. but it's certainly not a phrase you can expect the prime minister to be uttering. fresh from his talks in brussels this week, the brexit secretary gave a speech to business leaders in washington today and tried to laugh away his colleague's controversial comments. i never comment, i know what you're doing, i never comment on other ministers‘ views on these things. look, we are in a difficult, tough, complicated negotiation. i have said from the beginning it will be turbulent. what we're having at the moment is the first ripple. and there will be many more ripples along the way. critics here claim liam fox's talk of blackmail will only make matters worse. his language is intensely unhelpful. this is sabre rattling from a trade secretary who is twiddling his thumbs. because he can't do anything until the trade position of the uk has been resolved with the eu. the prime minister rounded off her trip cheering on the gb wheelchair basketball team. but when it comes to brexit the government is still searching for some big points, and will be hoping for more winning ways to come. eleanor garnier, bbc news, westminster. is brexit negotiations continue, um,, financial is brexit negotiations continue, um, , financial institutions is brexit negotiations continue, um,, financial institutions are ready looking for ways to minimise disruption to their business. amsterdam is proving a favourite destination with banks among the firms moving their. our business editor reports from the netherlands. amsterdam, home of the world's oldest stock exchange, mounting a new challenge to post—brexit london. i think it's very young, the cost of living is very good compared to london. and also being part of the continent. after the brexit outcome, we see companies moving to amsterdam, especially the more tax heavy companies, which need a european passport. the passport means companies in the uk can service customers in europe. that may not be possible after the uk leaves, which is why this company is setting up shop in amsterdam. europe represents around half of our business, the eu 27. so as there isn't clarity yet, of course, on the outcome of the negotiations, we need to be prepared for multiple different outcomes. hence we choose amsterdam. so what awaits those looking for a new european home? so, welcome. thank you. this is... harder to pronounce, but easier to afford, the cost of living and working in amsterdam is half that of london. nice view on the canals. you can cycle to work, or even fly back to the uk in underan hour. you may well be thinking, who cares if a few bankers leave the uk? well, apart from the jobs and the tax revenue they bring in, doing business under one roof, the one roof that is london, is very efficient. if you splinter all that business to the capitals of europe, it becomes much less efficient, and that increases the costs of banks and insurance companies, and they pass that on to their customers, and that means you and me. the chancellor would certainly care. he collected £70 billion in taxes from financial services last year. that is 12% of all taxes paid. it helps explain why the french prime minister didn't mince his words to me earlier this year. mr philippe, do you have a message for london? a message for london? come to paris. but in amsterdam, typically, they have a more laid—back approach. we haven't done any aggressive campaigning. first of all because i don't believe that companies are persuaded byjust an aggressive campaign. and secondly because london is our partner city, and i think a strong london is good for amsterdam, and vice versa. aggressive, no, but they are considering loosening the bonus cap and adding 1500 international school places. in the post—brexit beauty parade, this city means business. simonjack, bbc news, amsterdam. the former archbishop of westminster, cardinal cormac murphy o'connor has passed away. the leader of the roman catholic church in england and wales for nearly a decade, he was created a cardinal by popejohn paul the second. our religious affairs correspondent looks back at his life. ..may also keep us faithful to our lord jesus christ forever. cardinal cormac murphy—o'connor served as the head of the roman catholic church in england and wales from 2000 until 2009. he was a man of great faith and of great fun. he had an infectious laugh, and just loved to be cheerful and to encourage people around him. and it's that very, very positive attitude to life, which he saw as a gift of god, and to the challenges that we all face. his theological acumen was recognised early and he served as rector of the english college in rome before becoming bishop of arundel and brighton. and it was in sussex that he faced his greatest public challenge. god of power and mercy... a local priest, michael hill, had been accused of child sexual abuse. then bishop murphy—o'connor decided to redeploy him as a chaplain at gatwick airport. hill went on to abuse children and was jailed in 1997. cormac murphy—o'connor refused to resign, but described his management of hill as "a grave mistake." out of that terrible case came his decision to ask lord nolan to help him rethink how the catholic church in this country dealt with child abuse issues, to try and avoid such terrible things happening again. although he did not engage directly in politics, it was his careful nurturing that led tony blair to convert to catholicism in 2007, after he had stepped down as prime minister. a year later, cormac murphy—o'connor published a book entitled faith in the nation, in which he argued against the erosion of religious values in public life. it was this assertion, that the christian faith must play a role in the public square, that cormac murphy—o'connor had contended for throughout his life. the former archbishop of westminster, cardinal cormac murphy—o'connor, who's died, at the age of 85. kenya's electoral commission has come under heavy criticism after the supreme court annulled the results of last month's presidential election, citing irregularities. and the devastating floods across large parts of southeast asia have killed at least 1a00 people. floodwaters in houston may barely have begun to recede, but already scientists are studying the patterns and effects of storm harvey. michael wehner is one of those scientists — he joined me a short time ago. it is an unprecedented event, unusual in many aspects and, so, it is a serious tragedy for the people of texas but it is also an opportunity because of the high quality data, meteorological data that has been collected about the landfall of hurricanes that stalled out like this one did. and that is why it caused so much damage, it slowed down to a walking pace, didn't it? yes. this has happened before but it is not frequent. the copious amounts of rainfall that fell onto the houston area is of particular interest to me. i study the effect of climate change on extreme weather and it is my opinion that some of that rain, that total rainfall was increased by around 10—15% because of the warm temperatures in the gulf of mexico. you mention climate change. how do you think your research may outline the difference it has made or how we can approach these events in the future? there are two interesting questions. one is easy, one is hard. the easy one is how much more rain there was because it was warmer. the difficult question is did climate change have any influence at all on the chance of the storm stalling as it did? that is a more difficult question. these things will take some time to settle. there will be a difference of opinion among scientists. when somebody makes a hypothesis, they test it, they publish it, it is peer reviewed and if it passes peer review then the rest of the community will critique it with their own point of view. eventually, hopefully, the truth comes out. the former england football captain, wayne rooney, has been charged with drink—driving, after being arrested in cheshire in the early hours of this morning. the everton striker was released on bail this afternoon. danny savage has more. he is arguably england's highest profile footballer. wayne rooney captained the national team and holds the goal—scoring record for the side. rooney scores! he had many successful years at manchester united and has had a promising start to this season, after returning to everton. he's their new poster boy. but it's off—pitch activities that sees wayne rooney in the headlines today. in the early hours of this morning, he was arrested in cheshire for drink—driving. a few hours earlier, he was pictured on social media on a night out. he was stopped by police whilst driving a black vw beetle in wilmslow. beetle in wilmslow. cheshire police say the everton footballer was arrested just after 2am. 31—year—old wayne rooney will appear before magistrates in stockport on the 18th of september, where he can either admit the charge, or contest it. he made no comment to reporters, as he arrived back home this afternoon, driven by his agent, paul stretford. after just retiring from international football and making a new start at everton, this will be an unwelcome distraction for rooney, his club and his fans, as he starts a new chapter of his career. one of the most powerful x—ray machines at the baht has been unveiled in the german city of hamburg. -- ever built. the facility will be used to study the details structure of matter, atom by atom. hidden nearly a0 metres beneath german cornfields in hamburg's residential areas is one of europe's most ambitious, cutting—edge research projects. it will allow researchers for the first time to look deep inside matter. the xfel, as it is known, has been ten years in development, and is housed in a tunnel 3,500 metres long. the machine is a particle accelerator that, 27,000 times a second, can produce a brilliant and extremely short flash of x—rays. translation: the light flashes we generate are about 100 femtoseconds long, which is more or less the light needed to cross a human hair. reaching the moon takes about a second, so we generate extremely short light pulses, which allow us to freeze extremely quick reactions, for example, in biological material. what scientists say really sets the xfel apart is its super fast time structure in the flashes, which will catch proteins and catalysts in the very moment they are made or broken, and even make a film of that change. but the project's head is not driven by questions of immediate use. translation: i'm curious in what i may see in five or ten years. today, i would say, not for all the will in the world can i imagine the specific use of it. but, from the history of science, we see that often someone said there is no utilisation. what is the need of electromagnetic waves? researchers hope using xfel will lead to new routes in understanding the causes of disease, and to improve the efficiency of industrial processes. the project will begin operations with 11 nations as members of its consortium. a nurse at a hospital in the us state of utah has said she was assaulted by police after refusing to give officers a blood sample from one of her patients. alex wubbels declined the request, because the police didn't have a warrant or the patient‘s consent. the city's mayor has now apologised — saying it was completely unacceptable. the bbc‘s tim allman has more. the university of utah hospital in salt lake city. a nurse, alex wubbels, is talking to police officers. they want a sample of blood from one of her patients — the driver of a lorry, who was badly burned in a crash, and is now in a coma. he's not under arrest, he can't give consent, and the police don't have a warrant, so the nurse says they can't have a sample. ijust trying to do what i am supposed to do. that is all. in the end, one of the officers, named by local media as detectivejeff payne, decides he's had enough. done. we're done. you're under arrest. done. he grabs hold of the nurse and takes her into custody. screaming somebody help me! screaming visibly upset, she's taken outside and put in handcuffs — arrested, she believes, for simply doing herjob. the onlyjob i have, as a nurse, is to keep my patients safe. a blood draw is not — itjust gets thrown around like it's a simple thing. but blood is your blood — that's your property. now, the city's mayor has waded in, saying it was completely unacceptable, and that she's personally apologised to alex wubbels. the city's chief of police was similarly contrite. i'm sad at the rift this has caused between law enforcement and the nurses we work so closely with. i want to be clear: we take this very seriously. it's reported that the officer involved has now been stopped from collecting bloods, but has not been otherwise disciplined. the university of utah issued a statement, praising the nurse for her decision to focus, first and foremost, on the care and well—being of her patient. the headline is coming up surely, but first the weather. hi there. we've got some decent weather coming up to start the weekend. with high pressure in charge, we'll have some sunshine to start the day on saturday. mind you, some of you might have been woken in the night by the odd rumble of thunder. a few storms from lincolnshire, down through cambridgeshire, hertfordshire and essex, as well, all clearing out of away, hertfordshire and essex, as well, all clearing out of the way, and starting off then on saturday with relatively cool air in place. temperatures 10—12 degrees in the towns and cities, but cooler than that out in the countryside, so certainly a chill in the air. will be fine start to the day, though, on saturday. i mentioned the high pressure with us, that is going to bring some sunny spells. but the second half of the weekend will bring a change in the weather. we'll have a bright start for many, but outbreaks of rain will work in from the west. ok, here is saturday's weather forecast, and it should be a glorious start to the day, with clear blue skies for many of us first thing saturday morning. into the early stage of the afternoon, there will be a little bit of cloud bubbling up, particularly across parts of southern and eastern scotland, eastern areas of england, and that cloud could bring one or two very isolated, light showers. but the vast majority will enjoy fine and dry weather. it will tend to cloud over, though, for western counties of northern ireland as we go through saturday afternoon, the breeze picking up here ahead of a weather front. but for england and wales, plenty of sunshine around, and in the sunshine, widely, we'll see temperatures climbing into the high teens to low 20s. the highest temperatures probably around london and the south—east of england, at around 22 celsius, so very similar to what we had yesterday. it will feel pleasantly warm in that sunshine, but there are those isolated showers towards the coastline of essex and into parts of east anglia. here is the charts from saturday into sunday. we lose this area of high pressure. these weather fronts on the way. they will begin to show their hand as we go through the night time, with an area of rain working into northern ireland first, and then later in the night we'll start to see the cloud thicken, and outbreaks of rain arrive on strengthening winds across the south—west, wales, the north—west of england, and western parts of scotland, too. it will be a relatively mild night, though, as the clouds continue to work in, 12 to 15 degrees for saturday night. here is the chart for sunday — well, quite a different day. a bright start, yes, for eastern scotland and central and eastern england, but the brightness will not last. we will see the cloud thicken up, as this band of rain pushes its way east, with with one or two heavier bursts around. even behind that rain, at will probably stay cloudy at times, before brighter spells come in. monday will have a few spots of light rain and drizzle across western coasts and hills, and more persistent rain working into the north—west. despite the cloudy conditions, temperatures are not doing too badly, highs again about 22. that's your weather. this is bbc news. the headlines: there have been celebrations in kenya after the supreme court annulled last month's presidential election and ordered a rerun. president uhuru
