the liberal democrats say they'll stop brexit if they win the next election and form a government. at their conference, they promise to abandon our departure from the eu without another referendum. former prime minister david cameron says boris johnson only supported brexit to further his political career. it comes as mrjohnson prepares to go to go to brussels for new talks. also tonight: tear gas and water cannon fired at pro—democracy demonstrators in hong kong. a new police campaign

against knife crime — fronted by a convicted killer. more evidence of climate change — the dead sea shrinking by a metre a year. —— the dead see. and england salvage some pride in the ashes — winning the fifth and final test. good evening. the liberal democrats say they will cancel brexit altogether if they form the next government. at their party conference today, they adopted a new policy — to abandon our departure from the eu without having another referendum. their leaderjo swinson said it makes the liberal democrats the stop brexit party. our political correspondent jonathan blake reports from the lib dem conference in bournemouth — and his report does contain flash photography.

the liberal democrats have just taken their stop brexit stance a step further. so far, they've supported a second referendum as a way back from leaving the eu. all of those in favour of the motion, please raise your speakers‘ cards. but the party has now voted overwhelmingly in favour of revoking article 50 to pull the plug on brexit if it wins a general election. the policy is very clear. if the liberal democrats, at the next election, win a majority, if people put into government as a majority government the stop brexit party, then stopping brexit is exactly what people will get. yes, we will revoke article 50. it's an easy sell to most members here, who see stopping brexit as their mission, but it didn't pass without some dissent.

senior figures deny the policy is at odds with the party's ethos. you are the liberal democrats, is it not anti—democratic to overturn the result of the referendum without putting that question to the people again? it will be no surprise to people if, having elected us in a majority government, that we then deliver on that policy. until then, of course, because we've not yet got a general election campaign, we will continue to campaign for a people's vote. life's not bad for the lib demsjust now. record membership, signs from opinion polls in the recent european elections that their anti—brexit message is winning them support, and yet another mp coming on board. the former conservative sam gyimah is the latest to jump ship. his defection last night delighted delegates, but some here are worried that welcoming former tory and labour mps with such open arms will weaken the liberal democrats‘ identity. and then what? do you scrape it? cancelling brexit without another referendum would only be possible

for the lib dems if they won a general election — unlikely, but that won't stop them from doing their best to build on their recent success. jonathan blake, bbc news, bournemouth. meanwhile, the former prime minister david cameron has accused borisjohnson of only supporting brexit to further his political career. in the latest extracts from his memoirs, he said mrjohnson did not actually believe in brexit. here's our political correspondent chris mason. these two used to be on the same side. we're going to do blue team. do you want to go in goal or up front? i'll go here. but now borisjohnson‘s attempts to deliver brexit as prime minister come with a running commentary about his character from david cameron. mr cameron, who led the remain campaign, has some scores to settle with mrjohnson, the leading light of leave. in his memoirs, serialised in the sunday times, david cameron writes...

you could not accuse us of being anti—european! but mr cameron is accusing him of a loose affiliation with the truth and questionable motives for endorsing leave. nonsense, say his supporters. remain would have been the easier career choice, so borisjohnson led the campaign, he did so because he believes in brexit and he is committed to delivering it. from silly hats to high office, some of the biggest names in the leave campaign just so happen to be among the biggest names in the government now. and mr cameron's book is a production line of put—downs. on michael gove he says... this morning, michael gove was keen to keep up with the news...

are you upset by mr cameron's comments? he's accused you of being a faragist, of becoming a populist. how do you feel about that? ..but rather less keen to tell us what he made of it. the now home secretary had no such qualms, though. david cameron said he was most shocked at how she as a minister during the referendum campaign had been willing to rubbish her own government. the referendum has happened, we've all moved on and the fact of the matter is we're now working to deliver that referendum mandate. that is so important. there is no point going over the past. thank you. david cameron left the political stage three years ago, but the noisy publicity surrounding his book will provide the soundtrack to the week ahead. and chrisjoins me now — some uncomfortable reading for the prime minister ahead of another important week for him? that's right, a busy week for the prime minister. tomorrow he heads to

luxembourg, he will bejean—claude juncker of the european commission, his first meeting as prime minister. —— he will need to. there is not much time to get a deal or much detail about it, he says he will like one but will tell mrjuncker that britain will come out of the eu at the end of october, come what may, you will remember there is a law designed to stop that happening on the deal terms, borisjohnson told the daily telegraph that those who pass that law want to crush brexit. on tuesday the eyes of westminster will be on the supreme court as 11 supreme courtjustices examined whether the idea of suspending parliament is lawful. on wednesday the european parliament will discuss brexit. two thoughts tonight, there is a huge amount of noise around brexit news at the moment and it can lead us to be death of the scale of what is happening, a prime minister being challenged in court, challenged around issues of truth by a

predecessor. and there is a huge amount that is uncertain, six and a bit weeks to go until brexit we do not know if it will happen, when it will happen, who will be prime minister at the time and whether we will get a general election. thank you, chris mason. police in hong kong have used water cannon and tear gas against protesters throwing petrol bombs and bricks near government offices. thousands of pro—democracy campaigners marched in defiance of a police ban on rallies — this the 15th consecutive weekend of protests. there was also a demonstration outside the british consulate, as nick beake reports. how much longer can this go on? violence the authorities just can't extinguish. hardcore pro—democracy activists are not backing down, in what is a chinese city, even setting alight the police's latest weapon to try to wash away this protest movement. the police have decided enough is enough. they're making use of water cannon as well as the tear gas. it's worked for a time,

but we've just seen that this hard core of protesters just keep on coming back. because this is how the sunday afternoons now unfold in hong kong. a radical element on the attack. but some say it's gone too far, hitting the economy and frightening off tourists. why not film you? can ijust ask you, why do you think violence is still the answer? earlier, tens of thousands had marched peacefully, defying the threat of arrest and demanding an investigation into alleged police brutality, and demanding more freedoms for hong kong. # god save the queen... others, in much smaller numbers, called on britain to stand up for its former colony. but china has warned both the uk and the us not to meddle. the hardcore crowds finally left when these powerful

jets were unleashed, the water dyed blue to stain activists who can later be arrested. this is a battle for the streets, and for the future of the city. but how much longer can it take on this violent path? nick beake, bbc news, hong kong. after falling for several years, knife crime in england and wales is now rising again for the fourth year running. there were over 43,000 offences in the year to march — the highest since records began. over 4,000 were in the west midlands, where nearly 700 children were the victims last year. well the west midlands police have launched new anti—knife campaign, fronted by a convicted murderer. sadam essakhil was 15 when he and a friend stabbed a man to death. police hope his message — delivered from prison — will have an impact, especially on other young people,

as phil mackie reports. i just went out there, feeling that i need to protect myself. and obviously one thing leads to another and you never, ever think you're going to kill someone... the face and voice of killer. when you actually think about it, you don't need that knife. a lot of the times, i used to think i'm protecting myself... sadam essakhil was just 15 when he took another man's life. now, having just turned 20, it's hoped his message, filmed in prison, will persuade others not to carry knives. it's been shown to year eight pupils at the bluecoat academy in walsall. it's literallyjust on our doorsteps and something so bad could happen so quickly and it only takes someone like that to... to, like, lose someone's life. hopefully it doesn't happen to you, but just to think that it could have happened to you, it'sjust scary. around my area, a lot of bad things happen. like a few weeks ago there was a gunshot fired. and carrying a knife, people carry for self defence, but what they don't realise is if they get caught,

carrying that knife around, so many bad things could have happened to them. it's still not clear why in may 2015 essakhil and his friend abdullah atiqzoy launched what was described in court as a sudden, brutal and shocking attack on two men they didn't know in the street in birmingham. one man was critically injured. he later recovered. another, lukasz furmanek, dying. this is where he was killed. his mother has said that her life has been completely devastated ever since, and she can't forgive those people responsible. but she hopes that sadam essakhil‘s message will help prevent further knife crime. when we realised and he committed... that he has done the mergea... —— that he had turned the murder. and it's notjust the victims' families' lives that have been ruined. he is ashamed on that he feels sorry for the family, that obviously we can't give him...

we can't give that life back to him. do you think that what he's done with this video will atone for what happened four years ago? i spoke to him on the phone, he said at least i'm doing something good now, to give a message to other people. lukasz was an only child. this is the audience they wanted to reach, and the man speaking to them is the detective that led the murder investigation. he admits that using a murderer to front the campaign is controversial. we know he's in prison. it's not a decision that's been taken lightly, but ultimately this is about getting to the children within the school and talking to them in a language that they understand, and it's somebody that can come across and give that message who i think is really important. it's better than ending up injail with a life sentence, or killing somebody. he isn't eligible for parole for another 15 years, and police hope his message to teenagers will help stem knife crime. the person that died, that was his mum's only child, and that child is not there anymore. phil mackie, bbc news, walsall. the european union warned of a real threat to regional security in the middle east after attacks on saudi oil plants that risk disrupting global energy supplies.

us secretary of state mike pompeo has blamed iran for yesterday's drone attacks, but iran has accused him of deceit. our correspondent nawal al—maghafi is here to consider the implications. the aftermath of ten drone attacks that struck at the heart of saudi arabia's oil industry — disrupting the world's supplies. the missiles hit hijra khurais, one of the country's largest oil fields, and abqaiq, which processes about 8% of the world's total oil daily and is the world's biggest crude stabilization facility, really hitting the heart of the saudi economy. more importantly, it's escalating tensions between saudi arabia and the united states on one side, iran on the other. america has blamed iran directly, but they say that the us is using it as an excuse to instigate war.

houthi rebels, backed by iran, claimed responsibility. if true, it would be the biggest attacks in saudi arabia intervened in yemen's wall. the us says that the houthis has the long—range drums, making it possible it was launched from yemen. this would not be the first time the houthis used drones. just last week and attacked by houthis hit a military parade, killing dozens. saudi arabia says there won't be an oil shortage — but the more worrying outcome is a further rise of tension in the region. ben. thank you. four small boats carrying 41 migrants have been intercepted in the channel. they were stopped by the uk border force and brought ashore to be medically checked and questioned by immigration officials. they were of iranian, afghan, turkish and malian descent. prince william has praised the former welsh rugby international gareth thomas as a legend

after revealing he's hiv—positive. thomas, who came out as gay ten years ago, says he's been living with the virus for years and had kept it secret because he feared he'd be treated like a leper. daniel davies reports. dawn on the first day of living publicly with hiv. gareth thomas embarked on the ultra endurance ironman wales triathlon today after revealing a medical condition he'd tried to keep secret. i've got hiv, and it's ok, like. that's what i want to learn more than anything. this is how he first came to prominence, breaking records on the rugby field, known to fans as alfie. he came out as gay at the end of his playing career. now, in a bbc documentary, he says he wants to break the stigma of hiv. one of my fears is that all of a sudden who i was prior to people knowing i have hiv

might be forgotten. cheering. in fact, on social media and on the streets of tenby today, the support for him was obvious. it's hugely significant for somebody with such a high profile to talk about living with hiv. medical advances means now that somebody on effective treatment can have a normal lifespan, and really importantly, they can't transmit the virus to their partners. but the stigma associated with hiv hasn't shifted at all. shouts of encouragement. at the finish line, his husband stephen was waiting. 45—year—old thomas is one of an estimated 100,000 people in the uk living with hiv. he hopes this emotional announcement ona he hopes this emotional announcement on a gruelling day will help change attitudes towards the condition. daniel davies, bbc news, tenby. with all the sport now, here's karthi gna nasegaram at the bbc sport centre.

good evening. it has been a spectacular summer of cricket with england winning the world cup, and today they were victorious in the final ashes test against australia. but with the series drawn at 2—2, it is australia who retain the ashes urn. joe wilson reports from the oval. one red bull and 11 batsmen dressed in white, england's plan for sunday run something like this, exactly like this. stuart broad brilliant again. after harris and warner, the biggest wicket, steve smith caught by stokes. finally they got him cheaply connor smith departed for just 23. but matthew wade was defying england. temperature rising, his contest with jofra archer was frozen in time. anyone blinking? joe root needed someone else to get rid of weight, hidden, bestialstamping and wage gone for 117. then the

tumble resumed. rich called for the match, england levelled the series but the ashes urn remains with holders australia. —— ridge called for the match. this was a summer england won the world cup and did not lose the ashes. they surely deserve that final smile? after three days' play, it all came down to the final putt in golf‘s solheim cup, with europe beating the united states by 14.5 points to 13.5 points. suzann petersen, currently ranked 665th in the world after having a baby, sank the winning putt and then promptly retired from golf. sarah mulkerrins reports from gleneagles. six years since europe won the solheim cup, six and a half points was the target for victory. if the players were feeling the heat it was not showing. scott catriona matthew skippered the side, and with georgia

whole of england proving a cut above, early momentum went their way. at the power began to shift and whenjessica way. at the power began to shift and when jessica korda sank way. at the power began to shift and whenjessica korda sank this point, the american charge was on. after three days of little separating the sides it came time to the final putt on the final hole. suzann petersen, out of the sport for two years after becoming a mother, no sign of rest. after a day in the scottish sun saw the need to inconsistently, it came down to that sensational finish. a wild card pick more than justifying his selection from a brave captain, saluted by a crowd treated to a sporting spectacle. match of the day two follows soon on bbc one, so it is time to pop out of the room if you don't want to know today's premier league results. a late penalty for watford meant their game with arsenal finished in a 2—2 draw.

it was the start of quique sanches flores's second stint as manager of watford. also today, bournemouth beat everton 3—1. there's more on the bbc sport website. thank you very much. over the last few weeks we have been focusing on the changing climate, and today we head to the middle east, which scientists estimate average temperatures in summer could be up to four degrees higher by 2050. bbc arabic‘s rami ruhayem has been tojordan — an already arid country — to see how climate change is affecting it. hot, dry and uninhabited. most ofjordan is desert. this country is one of the poorest in the world when it comes to water, and climate change is making things worse. the dead sea, one of the world's most iconic spots, is shrinking fast. the shoreline here is receding at an alarming rate. the water level drops by one metre every year. the main cause is the diversion of water from thejordan river over the past decades by several states.

but climate change acts as a threat multiplier, that is a term increasingly in use when it comes to the subject. the idea is that many problems that are already there are made much worse by the rise in temperature. and it is notjust the dead sea that is suffering. those in rural areas are the hardest hit by climate change. translation: in the early 19805 you would walk around and it was like walking into a forest. but a few years later, a drought suddenly seemed to take over the area. you would no longer see so many trees. so, farmers started leaving their farms. many who leave head to the cities and the highlands where it is getting much more crowded. jordan has received huge numbers of refugees from almost every war in the middle east. to meet growing demand, the government has started pumping water out of the ground. many houses only get up to 24

hours of water a week, and over half the capital's supply comes from a massive pool of underground water, an aquifer. but aquifers need rain to fill up again, and it is raining less and less. well, according to the science reports, these aquifers can serve us up to 50 years. what happens after 50 years? after 50 years, we go to the deep aquifers. but the deeper they go, the more expensive it gets to pump the water up to the surface. and even that water will eventually run out. i always believe that the future generations, our kids, they won't forgive us what we are doing because we still have the time to act. but in a few years we will be beyond the recovery rate. many countries in the region rely on desalination, removing salt from sea water. but that uses a lot of energy, and jordan can't afford it.

on the bright side, jordan has sunshine and wind. with projects like these, it is taking its first steps to wean itself off energy imports. it is energy the country will desperately need to power its search for more water, as it heads towards a hotter future. rami ruhayem, bbc news, jordan. on bbc one, it's time for the news where you are. goodbye.

hello. this is bbc news with martine croxall. 11—year—old british skateboarder, sky brown, has achieved her best competition finish of the year, by winning bronze at the park world skateboarding championships in sao paulo, brazil. here she is in action.

the result means she's virtually assured of qualifying for next year's tokyo olympics. and that would make her britain's youngest ever summer olympian. james hope—gill from skateboard gb, has been telling me when sky first came to their attention. we have known about sky for a number of years and she started skateboarding quite young, but the skateboarding community in the uk has been aware of herfor four or five years. she's very prolific on instagram and it's hard to miss her if you are into skateboarding, so we've known for a while that she's very special. what it is about her? raw talent or incredible commitment to the training? there's not really any such thing as training with skateboarding, they would call it practice because it's a lifestyle

sport and it is your life, and she skateboards for fun and we don't put pressure on her in term of giving her a training regime and our attitude is for her to go out and have fun and when you go to tournaments, have fun and that is what she does and she's very, very good at skateboarding and she has fun. she's only 11. how many other girls or children is she inspiring? a huge amount. anecdotally when she came across to the national championships and we announced the gb tean in april a lot of skating shops were telling us and skate parks that a lot of girls were inspired by them and they were trying skateboarding for the first time. and she is very clear around her mission, if you like, even at the tender age of 11, that she wants to inspire girls and wants to tell girls that you can achieve anything you want if you put your mind to it, and it doesn't matter how young you are. we are looking at some pictures

i think of her family and they must be incredibly dedicated to her skateboarding career as well then, because they find themselves in brazil. yes, they are, absolutely. it's a skateboarding family and the family's from cornwall and herfather was someone he went over to japan and because it's a lifestyle it becomes part of the family, so they are pretty dedicated and they are a great family. very well grounded and they are looking out for sky and making sure that if she wants to skateboard, she can skateboard and if it turns out she doesn't want to skateboard, thatis fine and she will do something else. how likely is it that she will make it to the tokyo olympics and, even better, get a medal? well, absolutely. we are now able to show

she can get to the podium, and coming third in the world championships it shows there is potential she can get a medal in the olympics. the way the qualification process works, and we are confident she will qualify, she's just finished season one and has another coming up but the number of points she has achieved through coming third and the other results she has had, it will be very hard for her not to be in that top 20 that qualify to the olympic games. we are very confident that she will be on the top five or six, at worst, really. stay with us because we'll be taking an in—depth look at the papers with our reviewers lynn faulds wood and giles kenningham — that's coming up after the headlines. time for a look at the weather with philip avery. hello, once again. for some, sunday has been a really decent sort of day and when the weather is that good, you really would sit around in it but it hasn't been like that everywhere. we
