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. our political correspondent, chris mason, has been taking a look at what lies in store for borisjohnson and brexit this week. tomorrow he heads to luxembourg to meetjohn could yorker does make jean—claude juncker. there isn't much detail but he says he wants a referendum but his will tell him if he doesn't get one the uk will come

out of the eu come october, come what may. there is a law that stops that happening. mrjohnson tells the daily telegraph tomorrow that those who passed the law want to crush brexit. on tuesday, the eyes will be on the supreme court as 11 supreme court justices examine on the supreme court as 11 supreme courtjustices examine whether the idea of suspending parliament which has now happened, 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 deaf around the scale of what is happening. a prime minister being challenged at the court, a prime minister being challenged by the issues of truth by a predecessor. six and a bit weeks to go to brexit and we don't know if it will happen, how it how and we don't know if it will happen, how it will happen, who will be prime minister at the time or when we will get a general election. 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. 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. wright we have now seen 99 days of this. 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 has risen 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. 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's just scary. around my area, a lot of bad things happen. like a few weeks ago there was a gunshot fired. and, like, carrying a knife, people carry for self defence, what they don't realise is if they don't get caught, carrying that knife around, so many bad things could have happened to them. wright the two men in prison launched what was a shocking attack on the streets 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 murder... and it's notjust the victims' families' lives that have been ruined. he is ashamed on that he feels sorry for the family, but 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 who 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. 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 was waiting. thomas is one of an estimated 100,000 people in the uk living with hiv. he hopes this gruelling day will prove they need not be limited by the virus. daniel davies, bbc news, tenby. the headlines on bbc news: david cameron accuses borisjohnson of only backing leave in order to further his own political career. the liberal democrats pledge to cancel brexit if they come to power at the next general election. police in hong kong fire tear gas and water cannon to disperse pro—democracy protesters. sport and for a full round up, from the bbc sport centre, here's adam wild. good evening. we'll start at gleneagles where europe put on a sensational display to win the solheim cup. in a dramatic finish, they won the last three singles matches to win back the trophy

from the united states. there was just one point in it. our reporter sarah mulkerrins was there. 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 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 sensationalfinish. a wild card pick more than justifying his selection from a brave captain,

saluted by a crowd treated to a sporting spectacle. i always think sol home everything else. because it is notjust about you, you pave your today was absolutely a team effort for us to win the singles and prove we can do it on sunday. so really a lot of fun. away from gleneagles, australia may have already retained the ashes but england won the fifth and final test at the oval to level the series at 2—2. england were dismissed in their second innings early on the fourth day, leaving australia chasing a target of 399. despite matthew wade's second century of the series, england completed a 135 run victory, with jack leach and stuart broad each taking four wickets. here's our sports correspondentjoe wilson. one red ball and 11 batsmen dressed in white, england's planned

for sunday ran something like this. exactly like this. stuart broad brilliant again. after harris and warner there was the biggest wicket. smith departed for just 23. now matthew wade was defying england. at afternoon, temperature rising, his contest with jofra archer was suddenly frozen in time. anyone blinking? joe root needed someone else to get rid of wade — him. wade finally gone for 117. the need to resume. the final moment belong to england's upton, rue's as for the match. england levelled the series but the ashes own remains with the holders, australia. so on the final evening of this longest summer was, what should they be? this was the summer they won the world cup but didn't

lose the ashes. they deserved that final smile. he has been a paine really, for me. he is obviously the number one batter in the world —— paine. for a reason. number one batter in the world —— paine. fora reason. in difficult conditions he has stood up and done something very special. and been the difference, really. to the premier league then, where watford fought back from two goals down at half—time to draw 2—2 at home to arsenal. quite some start for quique sanchez flores in his first match since being reappointed watford manager. pierre—emerick aubameyang scored twice in the first half to put the visitors in front, but they really unravelled after the break. tom cleverly taking advantage of some incredibly sloppy play by the gunners. that made it 2—1 before roberto pereyra rolled in a late penalty to help watford take only their second point of the season. and there were four goals

at bournemouth too. they moved up to eighth in the table with callum wilson scoring twice in a 3—1win over everton. and great britain won four golds on the final night of action at the para—swimming world championships in london. alice tai finished as the most successful athlete with seven golds. great britain teammate, brock whiston made her gigabits debut, beating her own world record to win the sb8100m breaststroke. she then went on to win gold in the women's freestyle relay alongside tai, steph millward, and toni shaw. that's all the sport for now. 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 to jordan, an already arid country, to see how climate change is affecting it.

hot, dry, and uninhabited. most of jordan 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 well‘s most iconic spot, is shrinking fast. the shoreline there 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 cause is the diversion of water from the jordan river over the cause is the diversion of water from thejordan river over the past decades by several states, but climate change acts as a threat multiply. that's 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 rising temperature. and it's not just worse by the rising temperature. and it's notjust the dead sea that's suffering. those in rural areas are the hardest hit by climate change.

translation: in the early 80s you would walk around and it was like walking through a forest. but a few yea rs later walking through 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 her to the cities and the highlands, where it's 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 started pumping water out of the ground. many houses only get up to 2a hours of water all week. and over half the capital's supply comes from a massive pool of underground water, and aquifer. but aquifer is need rain to fillup and aquifer. but aquifer is need rain to fill up again and it's raining less and less. well, according to the science reports,

the aquifers can last 50 years. what happens after 50 years? after 50 yea rs happens after 50 years? after 50 years we will 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 would eventually run out. i always believe that the future generations, our kids, they won't forgive us about what doing. because we still have 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 seawater. at that uses removing salt from seawater. at 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 has taken its first steps to wean itself off energy imports. 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. a second world war veteran took to the skies in a spitfire this afternoon, to mark battle of britain day, the 15th of september, when the royal air force turned the tide against the german luftwaffe in 1940. george dunn, who's 97, undertook the flight to thank people who've raised thousands of pounds for the raf benevolent fund. kathryn stanczyszyn reports. this is how it feels to be back in a spitfire after seven decades. 97—year—old george dunn is no stranger to the skies, joining the raf aged 20. a lot of the battle of britain took place over sussex and kent, so, i did see a lot of it. and i suppose, being young, and looking up there and seeing the aircraft flying around, dogfights with the germans, and i thought, well, i think i'll have some of that. he carried out 44 missions

during the second world war for bomber command. when the war ended, he flew spitfires. you couldn't have any instruction on them in those days, because there wasn't a dual aircraft. so, it was a question of getting in and making the best of it. he has since helped the raf benevolent fund raise tens of thousands of pounds by telling his story. this is a thank you. it was still exhilarating, to be there, flying it, knowing it was yours — marvellous. the special flight also marked 79 years since the battle of britain, remembering all those who took part in that crucial campaign. of course, george is a piece of living history himself, and despite it being more than 70 years ago, he says taking those controls today, he felt like he had never been away. could have done with it being a bit longer. kathryn stanczyszyn, bbc news.
