the prime minister says the case is closed after the defence secretary, gavin williamson, was dramatically sacked yesterday over leaked details from a national security council meeting. but today, opposition parties have stepped up their calls for a police investigation into whether the official secrets act was breached. gavin williamson continues to deny telling the daily telegraph about discussions over whether the chinese firm huawei should help to build the uk's 5g mobile network. our deputy political editorjohn pienaar is in westminster for us. after sacking gavin williamson for breaching the confidentiality of one of the government's most secretive committees, theresa may is clearly hoping she might have enforced some discipline on her famously ill disciplined government, may be asserted some authority for what remains of her premiership, if that's possible. if the prime minister believed she could sack a senior minister and leave him accused not just of

senior minister and leave him accused notjust of leaking, but lying, and that row might blow over swiftly, she was wrong. it hasn't. why haven't the police been called in over the leak, prime minister? out she came today to greet a visiting leader and was greeted by this. are you certain you've got the right man, prime minister? and this. is mr williamson a liar? and this. was there a kangaroo court, prime minister? nothing more to say, but yesterday she judged and condemned gavin williamson — just a day after he denied he was the guilty man. absolutely not. but he has admitted speaking to the daily telegraph, after the national security council discussed giving china's huawei corporation a hand in building britain's 5g network. he denies leaking that. now, career wrecked, future blighted, he's not going quietly. he's told journalists... it was a witchhunt from the start in a kangaroo court. "it's the pm's attempt at a show of strength," he told another. "i couldn't have volunteered more information." and to yet anotherjournalist,

"i swear on my children's lives that i'm innocent." but to the government today, it's an open—and—shut case. the prime minister has said that she now considers that this matter has been closed, and the cabinet secretary does not consider it necessary to refer it to the police, but we would, of course, co—operate fully should the police themselves consider that an investigation were necessary. and the message to ministers? members should speak with complete candour within the room and shut up when they get outside. not so fast, says the government's opponents. the prime minister has sacked the secretary of state for defence because she believes there is compelling evidence that he has committed a crime. but despite that, she does not believe he should face a criminal investigation. where is the justice in that? and some tories want to be sure the case for the sacking was airtight. natural justice demands

that the evidence be produced so that his reputation can be salvaged or utterly destroyed. doesn't it?! could itjust be possible that the kangaroo court has made a mistake? to critics, though, it's cabinet conduct in the dock. some members just have completely swept aside any scraps of decency and honour in the pursuit of blatant personal ambition. no ifs or buts, this matter has to go to the police. but there's been no sign the police will be called in. a court case must show beyond doubt that secrets were damagingly betrayed. far simpler for mrs may to decide, on what she'd been told, she no longer trusted her defence secretary, and if ministers are somehow persuaded that destabilising leaks must stop, she won't mind that one bit. and gavin williamson, never shy, often on social attention, he wasn't always friendly as he sometimes looks.

close to mrs may and then as chief whip, he learned the secrets and stories deep inside government. tonight, he's posted this. looks harmless, but he could still cause trouble for the pm who's sacked him — as if she needed more. john pienaar, bbc news, westminster. britain should drastically cut its carbon emissions over the next 30 years and lead the globalfight against climate change. that's the view of the government's independent advisers, who say the uk should cut greenhouse emissions to virtually zero by 2050. scotland's target is five years sooner, that's because of the country's potential to plant more trees. but wales has five years longer because of its reliance on agriculture. northern ireland doesn't have a specific target, because of the lack of government in stormont. today's report says we must all do our bit turn down the heating, eat less meat, take fewer flights, and switch to electric cars. here's our science editor, david shukman. a heavy swirl in the north sea

as we travel to a new wind farm. every swish of the blades generates zero—carbon power. until recently, this was one of the most expensive sources of energy, but breakthroughs in technology have dramatically lowered the costs, so in their report the government advisers say a sevenfold increase in offshore wind should be possible. this is a good day in the north sea. imagine what it is like building and maintaining turbines out here in all weathers, but the country is getting more and more of its electricity this way, and the report says we need to install thousands more turbines if we are to take climate change seriously. that will be a huge challenge. it was britain with the industrial revolution that first started pumping out the gases that have been raising temperatures. now the report says britain could lead the way to a cleaner future and help limit global warming. we are responsible for a great deal of the warming the world is now

seeing, the climate change we are now seeing, but more than that we also consume a lot and those two factors especially mean the uk really means the uk to go further and faster earlier. the advice is that we will keep driving cars but they should be electric by 2030. eating red meat is ok but ideally 20% less of it. flying will continue, the report says, but shouldn't grow any more. and you should set your thermostat to 19 degrees in winter, assuming your home is well insulated. there is a glimpse of a low—carbon future in nottingham. they are drilling to install a new kind of heating for social housing. it draws warmth from the ground. the homes are also fitted with solar panels. in a communal energy centre there is a battery to store power. there is no need for gas. and monthly bills are far lower. joan warburton says it is a pleasure to live here. in the winter it was terrible,

even in the summer i was sat here with dressing gown on and socks on and the doors are shut, now you can see the doors are wide open, they are always open. i don't have a dressing gown on now and i don't have my socks on. i've never had socks on for 12 months so it's been great. last month, protesters demanded action on global warming. what do they think of the new plan? we are still living in the thing that if ijust turn the thermostat down, if ijust take one less flight, it is all going to be ok, and i think the truth extinction rebellion are telling everyone, this is not going to be ok, stop kidding yourself. you will have to make fundamentally different choices. in any event, major change is likely. here, a new blade for a wind turbine is tested. it's a staggering 88 metres long. new designs like this mean it is plausible that by 2050 britain will not add any more to global warming, but the key question is what the government will do and whether it will agree to push for a zero—carbon future.

david shukman, bbc news. you can find out plenty more information about climate change and today's report on the bbc website, including oui’ report on the bbc website, including our newjargon buster, which explains all the key terms. a burglar who was fatally stabbed by a pensioner in his home was lawfully killed. that's what an inquest ruled today. 79—year—old richard osborn—brooks described how he stabbed henry vincent with a kitchen knife at his home in south east london after being threatened with a screwdriver in april last year. mr osborn—brooks was initially arrested on suspicion of murder, but was later told no further action would be taken. richard lister reports. henry vincent's mother and sister arriving at court today, still furious that no—one's been prosecuted for his death. vincent was wanted in connection with another burglary when he went to the house at hither green armed with a screwdriver. he left it fatally injured. stabbing, stabbing.

they are trying to revive him, i think he's gone. the inquest heard today that, when threatened by vincent, richard osborn—brooks held up a knife, saying, "mine's bigger than yours, and if you don't leave my house, you'll be sorry." police initially arrested mr osborn—brooks on suspicion of murder before releasing him with no further action. but he received death threats which meant he couldn't return home. outside the house in the days that followed, the vincent family put up tributes to the man who'd gone there to threaten and stealfrom a pensioner. the tributes were quickly taken down by other residents, and the police had to intervene. it prompted a nationwide debate about the fine line between murder and self—defence. at vincent's funeral, feelings ran high, and there were threats made against journalists. but the coroner confirmed today that the 37—year—old was lawfully killed. richard lister, bbc news. the aerospace firm bombardier is putting its belfast operation up for sale as part of a reorganisation

of the business. it's the biggest manufacturing employer in northern ireland and employs almost 4,000 people. unions say the government should nationalise the company. the governor of the bank of england says interest rates could go up more frequently than expected in the next few years. it's currently being held at 0.75%. the market had been expecting just one or two interest rate increases by 2021, but mark carney said if brexit is resolved and inflation and growth continue to pick up, then more increases are likely. that would affect the 3.5 million people in the uk with variable or tracker mortgages. a fresh inquest is to be held into the death of nine—year—old ella kissi—debrah, who died after suffering an asthma attack in 2013. the original inquest concluded that her death was caused by acute respiratory failure and severe asthma, but her family says new evidence proves her death was directly linked to illegal levels

of air pollution near her home in south london. claire marshall reports. ella was cheeky and bright, says her mother. here she is playing with her phone in their car. this little cough a sign of how ill she was. a few months later, she had a severe asthma attack and died. i'm going home today. her home was just 25 metres from london's busy ring road. she was breathing air so polluted that it broke legal limits. pollution wasn't put as a cause of ella's death, but her mother has always believed that it was linked, and now she is one step closer to finding out. today, at the high court, a judge said in the interests ofjustice there should be a new inquest. we spoke to rosamund after the ruling. it's incredibly important. i loved her so much, so, so much, and i'm so proud of her, that she is doing this

for everybody else. even you and me, because we all breathe air. ella was rushed to hospital almost 30 times in the three years before she died. new medical evidence, key to today's decision, showed a striking correlation between these visits and spikes in air pollution. we've known for many years that air pollution and asthma go together, but what we haven't had are clear demonstrations of individual human beings suffering as a direct result of this pollution. the government says it's taking concerted action to improve air quality. ella's family will have to wait a yearfor the inquest, but it could prove without doubt that illegal air pollution can kill. claire marshall, bbc news. police in northern ireland say that any witnesses to the dissident republican murder of journalist lyra mckee will be offered anonymity if they agree to give evidence against her killers.

she was shot dead two weeks ago by the new ira, a killing which has sparked a backlash against the hardliners who continue to launch attacks more than 20 years since the signing of the northern ireland agreement that ended the troubles. our ireland correspondent emma vardy reports from londonderry on the efforts to stop the violence. # we shall live in peace, we shall live in peace... # the spectre of an old conflict still haunts this city. now derry is trying to heal new wounds. the violence which led to the death of lyra mckee was orchestrated by so—called dissident republicans. they see themselves as part of a decades—old struggle against british rule in northern ireland. i would just say to them, lay down your arms. stop the whole thing.

i would hope that they would take that on board. and this is the public face of modern—day dissidents, a legal political party known as saoradh — irish for "liberation" — who oppose northern ireland's peace process. police say saoradh are the political voice of the new ira — with a significant overlap in the leadership of the two organisations. nobody wants you — nobody! now their headquarters in derry have become the focus of a backlash. in the wake of lyra mckee's death, saoradh have had their account closed by twitter and have faced repeated calls from people to shut down their operations here. the group haven't responded to any of our requests for an interview, but in a statement on their facebook page told people they wouldn't be going away. as 11 men were convicted in derry this week for an illegal republican parade, we caught up with

the prominent dissident and leading member of saoradh, seen here in the bluejacket, thomas ashe mellon. mr mellon, we're from bbc news, we've got a few questions about saoradh. many people in derry don't want your organisation here, mr mellon. what do you have to say to them? people see you as having endorsed the violence which killed lyra mckee, mr mellon, how do you justify that? how do you justify that, mr mellon? you say you represent the community, but the community here have made it very clear you're not welcome. another problem, mr mellon, youth workers tell us that what saoradh does is deliberately target young people with your propaganda and that helps encourage people to go out rioting. you don't really care about their welfare, do you? is that responsible? saoradh is a very vocal organisation at times, very vocal on social media. what do you have to

say to people today? people feel dissidents like you are just trying to drag northern ireland back to the past. isn't that what you're doing? any words for lyra mckee's family? saoradh says it played no role in the death of lyra mckee. police have promised that witnesses who can identify the gunman will receive protection. the new ira, and their supporters, represent a tiny minority in northern ireland, but with new blood coming through their ranks, their presence will be difficult to erase. emma vardy, bbc news, derry. wikileaks wikilea ks co—founder wikileaks co—founderjulian wikilea ks co—founder julian assange has formally began a legal battle to avoid extradition to the united states to avoid computer hacking charges. he told a caught fire video link that he would not surrender voluntarily to us authorities. he is

serving a 50 week sentence for breaching bail conditions after spending nearly seven years in the ecuadorian embassy in london. the leader of plaid cymru, adam price, has called on anyone in wales wanting another eu referendum to back the party in the upcoming european elections. at plaid's campaign launch in cardiff, mr price said he wanted to "make wales matter in europe and the world." here's our wales correspondent sian lloyd. applause stepping up to the challenge of leading plaid cymru for the first time into an election campaign. adam price took over as party leader last september. today he was setting out his message to welsh voters, ahead of the european elections. we passionately want to remain in order to transform wales' future place and prospects inside the european union. plaid cymru currently has one of the four meps from wales, but they're a party still striving to make waves with the welsh electorate, who voted as a nation

to leave the european union. adam price talks of these elections as an opportunity to reach out to supporters of other parties who are dissatisfied over brexit. and we have to demand a people's vote and argue the case for remaining in the eu. we need to actually change things by taking power into our own hands as a country, placing wales at the heart of europe. he wants to navigate a new course for wales and is calling for a referendum on welsh independence if brexit is delivered without a second public vote. sian lloyd, bbc news. for the past 50 years, the royal navy has been patrolling continuously with nuclear armed submarines ina programme currently known as trident. tomorrow, westminster abbey will hold what's been described as a service of thanksgiving for the crews who conduct the patrols. but it's been condemned by the anti—nuclear campaign the campaign for nuclear disarmament. as our defence correspondent

jonathan beale reports, the government is already making plans to continue the operation for the next 50 years. flood, flood, flood in the diesel compartment! royal navy submariners are training for another patrol on britain's most expensive... emergency stations, emergency stations. ..and lethal weapon. diving stations, diving stations. these are the crews who man the trident nuclear armed submarines and who carry out the uk's longest unbroken military operation. at the faslane base, one submarine has just returned from patrol somewhere in the atlantic. the four boats are showing their age, but work's under way to replace them at a cost of more than £30 billion. the navy and the government say it's helped keep the peace for the last 50 years and will continue to do so for decades to come. and this is from where britain can fire her nuclear missiles. there are 16 tubes on board the submarine. at the moment, eight of those tubes

are loaded with trident missiles, and each missile can carry up to eight nuclear warheads, and each of those warheads is about eight times more powerful than the bomb dropped on hiroshima. this really is a weapon of mass destruction. for the crew, who have little contact with the outside world on duty, it is a huge personal sacrifice — on a machine that could wipe out cities. how does that feel? yeah, it's quite mad, isn't it? it's mad, that, to think, but for us, like, it's just get the job done in the galley more than anything. i've got a very supportive group of friends that are very proud of what i do, so i've not come across many people who have given me any flak for the job i do. and this is where they get the command — in these safes are the codes and keys and the prime minister's directions if britain ever came under nuclear attack. but what if the crew questions those orders?

if the submarine crew decided not to follow those orders, then that is possible, but our training and our doctrine and the circumstances whereby nuclear weapons would require to be fired, in my opinion, means that we would be able to follow those orders without question. gavin williamson came on board to thank the crews just before he was sacked. at least on the case for renewing trident, he was in step with the prime minister. it is not about status, it is about safety, it is about security, it is about deterrence. that's why we have an independent nuclear deterrent. it'll be up to his successor, penny mordaunt, to face the questions over whether britain can afford it and, if in future, it might be vulnerable to attacks from space and cyber. and the scottish government's already made clear it wants nuclear weapons out of these waters. jonathan beale, bbc news, faslane.

and to football, in the europa league, arsenal hosted spanish side valencia this evening, while chelsea travelled to germany to play against eintracht frankfurt. our sports correspondentjoe wilson was watching from the emirates stadium and sent this report. arsenal's season comes down to this — two legs of a europa league semifinal and then the chance of a trophy. the club's priority has changed course, towards azerbaijan. between them and the final, valencia. you'll spot their man in blue, diakhaby, outjumping three arsenal defenders, and so easy even a manager could have scored. well, valencia's manager thought so. ok, so arsenal's defence is dodgy, but what about attack? there they have a partnership. wherever aubameyang runs, lacazette is sure to follow. there he is. valencia soon lost sight of him again,

when lacazette watched his header, he was convinced it had crossed the line. a replay confirms it clearly, and goal—line technology told the ref it was in, via his watch. just 25 minutes gone, by the way. lacazette had ample opportunities to score again. instead of the net, he hit neto — that's the valencia goalkeeper. with the clock ticking to 90 minutes, a chance fell to the other half of the double act, aubameyang. 3—1 with the second leg to come. now, which way to the final? yes, we have been talking about the significance of this europa league competition right now to arsenal football club. you know, the same could be said, really, for chelsea. they were at frankfurt this evening in the first leg of their europa league semifinal, their goal came from pedro just before league semifinal, their goal came from pedrojust before half—time, and that made it 1—1, that is the way the game finished. i think chelsea will be content with that, a lwa ys chelsea will be content with that, always important to score the away

goal. so the strong possibility remains we could have two london clu bs remains we could have two london clubs competing at this european final in azerbaijan, sophie, just 4000 kilometres from london to baku. polls closed just under half an hour ago in the local elections in england and northern ireland. huw edwards with be with you throughout the night as the results come in. this is no normal set of local elections — they affect 248 councils in england and northern ireland, but they take place in the most turbulent political period since the second world war. how will the brexit stalemate affect the outcome, and what will that mean for the party leaders at westminster? join us at 11:35 tonight on bbc one for election 2019. here on bbc one, it's time for the news where you are. goodbye.

hello and welcome to sportsday. lacazette gives arsenal the upper hand in their europa league semi final. chelsea snatch a crucial away goal in their semi final with eintracht frankfurt. and the ecb say alex hales would still be in their world cup squad if his ban for recreational

drugs hadn't been made public. thanks forjoining us. alexander lacazette struck twice to put arsenal on top in their europa league semi final with valencia, three one their advantage after tonight's first leg. joe wilson is at the emirates. we should have him in a moment. and this is a big win for arsenal, one foot in the final and as we know win the competition and you qualify for the champions league. absolutely. it really has become this competition for arsenal, overlook may be in august but it

really co m es overlook may be in august but it really comes miss one ma because other than that, did that to look forward to? fifth place in the lead, but the thing that has been a real progress u nless but the thing that has been a real progress unless you get a trophy to back it up, it up, it is hard to feel that progress is really tangible. after 11 minutes of this match that i'd come i think a lot of the arsenal fans thought this is the arsenal we have seen the last premier league your last three defeats when they a three goals. beating their arsenal defenders there to put that into the net. and to give valencia that early lead. what have arsenal done this season? they have capped an attacking partnership. almost throughout. although the defence looked dodgy in the first half at times, continue to look dodgy, a bomb again could run with the ball and when he looked up, there was lacazette. there was the combination to make it 1—1 are important for the whole atmosphere of the evening for arsenal to get back into the game. and then a few minutes later, the valencia defence

and loss lacazette once again. their header, lacazette was convinced across the line. it did take a bit ofa across the line. it did take a bit of a goal line technology to sorted out. they came through. that made it 11. we have been playing 25 minutes then. 2—1. —— 1—1. 11. we have been playing 25 minutes then. 2-1. --1-1. it 11. we have been playing 25 minutes then. 2—1. —— 1—1. it became 3—1 but we had to wait until the end of the game. this time it was the other half of the double act, aubameyang finishing from close range. we will see that goal right now. there it is. squeezing it in between the near post in the goalkeeper. 3—1 so different then 2—1. you sense that in the reaction of the players and the manager and the reaction of the crowd. before the match, we were talking about which kind of arsenal might we see here this evening. the arsenal which has been dominated times in the europa league, their victory against napoli or what would be the arsenal that has conceded the

nine goals in the
