how some diesel cars produce double the toxic emissions of a lorry or bus. while china's pollution creates a smog cloud over its cities 2000 miles long. # you should come to my hood, my hood, my hood...# and is this the star of 2017? a 22—year—old singer—songwriter tipped for the top. in sportsday, we are at the london stadium for west ham against manchester city. good evening and welcome to the bbc news at six. a terminally ill man has begun a legal fight for the right to help for him to die.

noel conway, who's 67, has motor neurone disease and says he fears becoming "entombed" in his own body as his muscles gradually weaken. mr conway, who is being backed by the campaign group dignity in dying, wants a doctor to be able to prescribe a lethal dose when his health deteriorates further. the case will be the first high court challenge since mps rejected an attempt to introduce assisted dying in 2015. 0ur medical correspondent fergus walsh has this exclusive report. my name is noel conway. i have motor neurone disease. it's incurable and terminal. i fear very soon i shall be entombed in my own body, and the thought of that fills me with absolute horror. got you lunch, love. beans on toast, as requested. day by day, noel conway is gradually losing all strength in his body. increasingly, he relies on his wife, carol.

he is too weak to take his own life, so when his condition gets worse, he wants a doctor to be allowed to give him a lethal dose. it's my body. i have a right to die. i have a right to determine how i should die. and more importantly, when i should die. and i want to do so when i have a degree of dignity remaining to me. noel often relies on a ventilator to help him breathe. he is registered with the swiss suicide group dignitas, but will soon be unable to travel, so he is challenging the law here. our current law condemns people like me to unimaginable suffering. i mean, i don't have acute pain. i'm just heading, really, on a slow, slippery slope to hell.

noel was a keen walker, climber and skier. his family support his right to die but don't want to play a part in his death. it places me in an intolerable position. i can't help him to end his life. that would not be possible. i can't do that. i wouldn't want to do that. we need the assistance of professionals, of medical staff, to ease that passing. the courts have shown leniency with relatives involved in assisting a suicide, but campaigners, most recently tony nicklinson, have never been able to persuade judges that doctors should be allowed to end a life. this issue stirs huge passions, and when mps last voted, they rejected a change in the law. so does that mean this latest high

court challenge is doomed to fail? while it is parliament that makes the law, it is judges that interpret it. so when the case comes here, noel conway's legal team will seek a declaration that the current law is not compatible with his basic human rights, to live and die with dignity. under the 1961 suicide act, any doctor who helped end his life would face up to 1a years in prison. baroness jane campbell has spinal muscular atrophy and has been close to death on several occasions. a disability rights campaigner, she says altering the law would send dangerous signals. if the law were changed, it would feed into society's fear that to be severely disabled, to be trapped within your body, which i already practically am, is a state worse than death.

it would be a huge burden to us. we already have to fight for the right to live. please don't help us with the right to die. but that is exactly what noel conway wants. canada and california have introduced assisted dying in the past year. noel is determined it should happen here. it's not a bad day, actually. but he knows he may run out of time before his case is settled. and fergus is with me now. another challenge to the law less than two years after the last one was rejected. what chance that this will be successful? well, the campaign group behind this knows that they have no realistic hope of

changing the law to introduce assisted dying bill parliament. mps roundly rejected it two years ago, and that included the safeguards they wanted, that two doctors and a high courtjudge would need to approve each case and it would need to involve only terminally ill, mentally competent patients with less tha n mentally competent patients with less than six months to live. so instead of now trying through mps, through parliament, they are putting the proposals in a real—life case beforejudges to see the proposals in a real—life case before judges to see what they make of it. the last time this went up before the supreme court, two out of nine justices before the supreme court, two out of ninejustices said before the supreme court, two out of nine justices said base considered the current rule —— said they considered the current will incompatible with human rights. but those opposed will say, yes, have sympathy for people like noel conway, have compassion, but it is too dangerous to change the law. donald trump is being briefed by us intelligence agencies on how they believe russia conducted

a cyber hacking campaign to try to help him win the presidential election. he has been openly sceptical about it, and has described it in an interview as a political witch hunt driven by his political opponents. but the vice president, joe biden, said it's "absolutely mindless" for mr trump to claim he knows more than the us intelligence agencies. nick bryant has more. did a cyber attack on america organised by vladimir putin help put donald trump in the white house? us intelligence can't say whether votes were changed or opinions altered but they are convinced russia wanted the billionaire to win and conducted a multifaceted cyber campaign using hacking, propaganda and fake news to boost his chances of becoming president. it wasn't just the billionaire who celebrated his unexpected victory, according to us intelligence. intercepted conversations reportedly picked up senior figures in the russian government rejoicing, too, among them officials said to be aware of the alleged cyber campaign. donald trump will be told by america's intelligence chiefs

that the russians tried much harder to hack the computers of the democratic national committee than those at republican headquarters, and also that go—betweens have been identified who allegedly handed stolen e—mails to the website wikileaks. details from the classified report were leaked to nbc news, which has infuriated donald trump. "how did nbc get an exclusive look into the top—secret report", he asks. "who gave them this report, and why? politics". then he went on. vice presidentjoe biden said it was time for donald trump to grow up. the idea that you know more than the intelligence community knows, is something like saying

"i know more about physics than my professor. i didn't read the book. ijust know i know more." grow up. time to be an adult. you are president. donald trump this morning complained of a political witchhunt, and his spokesman said he is right to be cautious. the president—elect has a healthy scepticism of everything, and that's important. people need to know that when decisions are made, we've seen in the past that a rush tojudgment is not in the country's best interests. this morning donald trump got into an online dispute with arnold schwarzenegger over ratings for the tv show the apprentice. and so he continues with his unconventional journey to the white house, but troubled by that nagging question, did russia help him on his way? nick bryant, bbc news, new york. hundreds of people have attended the funeral in huddersfield of yassar yaqub, who was shot dead by police on monday on the m62 motorway. the inquest into his death

was opened this morning and heard that a gun was found in the foot well of the passenger seat, where mr yaqub had been sitting. danny savage has more. hundreds of people came to yassar yaqub's funeral at a mosque in huddersfield this morning. many didn't know him personally but were here to support his family. his father, mother and sisters were deeply distressed. the consistent thoughts from those present is that they want answers as to why he was shot by police on monday night. parents have lost their son. sisters have lost their brother. they need answers. his friends, family, they need answers. i think they need answers quick. as far as the gun culture is concerned and criminal activity is concerned, we strongly condemn that. but the question arises that the way this was carried out, in my opinion it was totally

out of order. investigators say they are working as swiftly as possible and keeping mr yaqub's family up to date. but one key question about the shooting was answered today. the police have already said a gun was found in the white audi yassar yaqub was shot in. we know he was the front seat passenger in the car. at the inquest into his death this morning it was revealed the gun was found in the front passenger footwell of the vehicle, exactly where he was sitting. yassar yaqub was listed in court as being a 28—year—old office clerk. he was once accused and cleared of trying to murder two people, and a firearms offence. his family and friends, though, stress he was never convicted of anything. meanwhile a 30—year—old man arrested on monday as part of the police operation here has appeared in court today charged with possession of a gun, bullets, and a silencer. moshin amin from dewsbury was remanded in custody after his

hearing at leeds magistrates. modern diesel cars produce more than twice as much toxic emissions as a lorry or bus of the same age, according to new analysis from the international council on clean transportation. the report comes as one road in central london breached its legal air pollution limits for 2017, just five days into the new year. 0ther london roads are expected to breach the limits shortly. richard westcott reports. it doesn't seem to make sense. how can small diesel car engine speed twice as polluting as the engines on 20 tonne lorries and buses? this research comes from the same group

that exposed vw cheating its emissions, so why do they think there is this huge difference between the latest cars and lorries? it is not about the technology, because the technology for cars and trucks is quite similar. it is more about the relation to how the vehicles are tested. for trucks, they are testing real trucks under real driving conditions, whereas for ca i’s real driving conditions, whereas for cars at its prototypes in the laboratory, which makes a very big difference. the research focuses on the average amount of poisonous nitrogen oxides being produced. lorries and buses belch out around 210 mg per kilometre. the latest ca i’s 210 mg per kilometre. the latest cars produced more than twice that amount. what is worse, cars can become six or seven times dirtier once taken out of the laboratories and put on the road. welcome to brixton road, london, which hasjust become famous for the wrong reasons. it has become the first st in britain to breach one of the

european pollution laws for nitrogen dioxide, a poisonous gas from diesel engines. the thing is, this is an annual limit, and it breached it in just five days. london is the worst, but many places around britain are breaking air—quality laws. but this isn't really about cars, but about the impact of pollution on our bodies. those particles get into the lungs and penetrate the lungs and get into the blood circulation. and there, they circulate to the rest of there, they circulate to the rest of the body, and that is where you get the body, and that is where you get the effects of pollution on not only the effects of pollution on not only the lungs, but on the heart, on the brain, on the immune system. car testing is about to get much tougher. new european rules are being rolled out from september but they will not be fully in place until 2021, so it will be years before the tests are as rigorous as they are for lorries. our top story this evening.

a man who is terminally ill with motor neurone disease begins a legal fight for the right to die. and still to come — we hear from britain's triple tour de france winner chris froome. he talks about doping in cycling and the future of the sport. coming up on bbc news, we will look ahead to the third round of the fa cup in sportsday. it starts here with west ham against manchester city but we've also take a closer look at some of the non—league teams. as i mentioned earlier, pollution is already a problem in london just six days into the new year. but imagine leaving your house and seeing this? this is beijing — which is currently experiencing one of the worst bouts of smog to hit the city in years — reducing visibility to less than 200 metres. and it's not just china's capital that has been affected. a smog cloud 2000 miles long is now blanketing cities from beijing to chengdu to hunan province —

leaving them on the highest alert for serious air pollution. 0ur china correspondent john sudworth reports from shiijazhuang in the last month has become china's most polluted city. somewhere, underneath this murky gloom, is a city of 10 million people. and for the unfortunate residents, this is normal. for the past 30 days, the average air quality in this city has measured as hazardous on the official scale. you can smell, even taste the coal dust in the air, the grim, tangible reality of this country's model of economic growth. and people have no choice but to live, eat and sleep in this toxic smog, 2a hours a day. "it's like living under a cloud", this noodle seller tells me.

"the smog is harming my children's health". "of course i want to leave", this man says, "but i can't afford to, and anyway, the whole country is polluted". it's not much of an exaggeration. 200 miles away, the pollution literally rolled into beijing earlier this week. and stayed. a toxic mix of coal dust from power stations and car exhaust. the smog now regularly blankets a huge swathe of northern china. and it is believed to cause more than a million premature deaths a year. public concern has forced the chinese government to begin investing heavily in renewable energy. those working in the sector believe china can clean up its air,

just as wealthier and more developed countries once had to. so the experience in the uk, they have spent, i think, over a0 years in solving the air pollution issues. now comes to china. actually, we don't need that much time for the science research. we don't need that much time to develop relevant technologies. so i think a lot of things are ripe for us to make faster solutions. those solutions can't come fast enough for this city. fossil fuels may have lifted china's economy to ever greater heights, but they are poisoning its people. john sudworth, bbc news. scotland's first minister nicola sturgeon has suggested her preferred option of a second referendum on independence could be put to one side if the uk follows a strategy of so—called soft brexit from the eu. let's talk to our scotland correspondent glen campbell outside holyrood, does this signal a change of heart by ms sturgeon?

does this single a change of heart? not quite, she remains committed independence. watch it has made clear today is that she would be prepared to put talk of another independence referendum on hold for at least the next couple of years. —— what it has. whilst brexit is being negotiated. if the uk government accepts her proposals for what she regards as a compromise. you may remember, she set out last month her idea of a compromise deal that would allow her to hold her nose and accept that travel tobacco leave m ea ns nose and accept that travel tobacco leave means leave if the scottish parliament becomes more powerful and if the uk government seeks to remain within the single market, or six a deal that would allow scotland to stay in. —— that leave means leave. theresa may is apparently considering these proposals. there are no signs that she is prepared to accept them. that is why nicola

sturgeon has taken to social media to say that she believes another referendum on independence is more likely than a soft brexit. thank you. britain's triple tour de france winner chris froome has been speaking about allegations of doping in cycling. he says they've been "bad for cycling and bad for sport" — and he said he would never take substances usually banned but that are allowed for medical reasons — as his former team mate bradley wiggins did. he's been speaking to our sports correspondent natalie pirks in monaco. 0lympic bronze and his third tour de france victory in four years, 2016 might have been a year to forget for some but not chris froome. whilst british cycling enjoys a golden age, off the road and track is mired in controversy with doping's blurred lines at the heart of it. a tue, or therapeutic use exemption, allows athletes to take a banned substance for genuine medical reasons. the issue is whether some have exploited the system for competitive game. —— for competitive gain.

just the fact that we're having that debate about authenticity of tues, i think there's a problem with the system. i think wada, the anti—doping authorities, need to tighten their regulations around tues, so that they're not something that is questioned. in those leaks by russian hackers it was revealed that froome's former team—mate, sir bradley wiggins, had received three tue injections before three major races in the space of three years. it's perfectly legal, but froome revealed to me he refused one in 2015 on moral grounds. i didn't feel as if having a tue in the last week of the tour de france was something was prepared to... itjust didn't sit well morally with me that that was something i was going to do. do you think, therefore, it's right we are asking questions, for example why bradley wiggins had three corticosteroids in the lead up to the races? sure, i mean, i think it's only healthy to ask those questions. froome's team, team sky, is currently the subject of a uk

anti—doping investigation over an incident involving a mystery package delivered to bradley wiggins in 2011. both parties deny any wrongdoing. i mean, it's not good for sport in general, the fact that we are discussing the validity of results and... and, as i said, that brings it back to the authorities and something that they hopefully need to tighten up on. as he attempts to win his fourth tour this summer, the doping questions will again come thick and fast. froome's biggest desire is to leave a cycling legacy no one will be left doubting. natalie pirks, bbc news, monaco. michelle 0bama has made her last speech as america's first lady. she was speaking at the white house — and it all got quite emotional. she gained her remarks at the country's students. i want iwant our i want our young people to know that they matter. that they belong. so don't be afraid. do you hear me?

young people, don't be afraid. be focused. so, i want to close today by simply saying... thank you for everything you do for our kids, and for our country. being your first lady has been the greatest honour of my life, and i hope i've made you proud. applause a 23 year—old singer songwriter called ray blk has won bbc music's sound of 2017 poll. it's the first time an unsigned artist has topped the list — which is picked by music critics to recognise emerging talent. the panel has an enviable record of picking future stars. recent winners include sam smith and adele. 0ur entertainment correspondent lizo mzimba reports. # don't make me beg #. the sound of list highlights
