welcome to bbc news. i'm mike embley. our top stories. president trump launches his re—election campaign for 2020 in florida. he says his supporters are part of a new political movement. it's a movement made of hard—working patriots who love their country, love their flag, love their children and who believe that a nation must ca re for its own citizens first. here in the uk, the remaining five candidates still in the race to become the next prime minister clash over brexit in a noisy tv debate. wiped off the map — satellite images show mosques in western china destroyed — the second of our special reports from xinjiang.

and a warning that the world is taking an unacceptable step backwards in the fight against measles. hello to you. president trump has officially launched his bid for re—election in 2020. he claimed the american economy was the envy of the world and he prompted the 20,000 supporters who turned out in orlando, florida, to boo what he called the "fake news media." he drew huge cheers announcing his new campaign slogan: "keep america g reat". we're going to keep fighting for every man and woman and child all gci’oss every man and woman and child all across this country. with every ounce of hard work we are going to keep making america great again and

we will indeed keep america great. we will keep it so great. better than ever before. we are going to keep it better than ever before. and thatis keep it better than ever before. and that is why, tonight, i stand before you to officially launch my campaign for a second term as president of the united states. thank you. well, the united states. thank you. well, the president is finished now. 0ur washington correspondent gary 0'donoghue is at the campaign launch in orlando. gary, it's been some surprise in social media to see his already campaigning, there are over 500 days to go until the election, but in a way he has never stop campaigning and he loves it. that's right. he's continued to hold rallies like this right through the first couple of yea rs of right through the first couple of years of his presidency as well. right up to the mid terms. he doesn't need an election as an excuse doesn't need an election as an excuse to do this kind of events but

this was paged and described as the loins of the 2020 campaign. if you look back at the last couple of presidents, it was a full year, really, later, that president 0bama and president bush went on the campaign trail. he's gotten into this a year early in many ways. i think that's because he sees the democratic field sucking up a bit of the oxygen, perhaps getting their message out there. he wants to get out there and do a bit of fighting. he thinks that the record is not being put straight and so tonight we re being put straight and so tonight were long list of what he said were his achievements. stop on the economy, some reruns of old favourites from the 2016 campaign, he's still doing the hillary clinton bed. that is still getting huge cheers and chance of lock her up from the crowds here. what we haven't seen tonight is any new road testing of original messages or original thoughts for the next campaign, perhaps it is too early for that. this is not a stump speech

you will see in a year's time from now, i think they will hone its and make it different. this feels as if we have heard this all before. gary, florida is a crucial stage in any presidential election but particularly significant for him? he calls it his second home, florida. he has mar—a—lago on west palm beach, on the eased coast, a bit further south from here. florida, of course, it's a purple state, a swing state. it's that date on election night, when it went his way started people to think, hang on, he could win here —— state. he has affection for that in that lens. it's also to some extent bucking the trend of the mid—term elections back in autumn when there was a wave of democratic victories that is of the house of representatives. here they held onto the governors mansion, and flipped a senate seat. he has a lot of

affection and support here in florida. gary, thank you very much indeed for that. let's get some more now. dave levinthal is federal political editor at the centre for public integrity and he joins us now from washington. what did you make of the speech? it was i going to listen to your favourite band in a way. sure you wa nt to favourite band in a way. sure you want to hear some of the new stuff, but while you are there is to hear the old head. donald trump had lots of old heads about hillary clinton, about the e—mails, about the 2016 campaign he served up as red meat for older people were there. make no mistake, it was an energetic crowd, a big round, the exact type of card that donald trump loves. donald trump has had more than 60 rally since becoming president of united states. he is a campaigner, it was the day of donald trump's inauguration where he filed

paperwork to run for re—election. it's not just paperwork to run for re—election. it's notjust today, he's been doing it for 2.5 years, this is just the icing on the cake in a way. what do you think of his chances. the economy is looking good and the received wisdom is when the economy as good a sitting president is usually re—elected. as good a sitting president is usually re-elected. donald trump can talk about investigations, there are many the democrats are going after him with. he can talk about all sorts of different things but really, pay attention to the economy, its pocketbook issues, the ability for americans, particularly in key swing states, which are likely to determine whether he becomes president or not next year — the economic numbers there are crucial. if the economy goes into the tank a year from now or if you months from now, that is going to be incredibly difficult for donald trump. conversely, if the economy continues to be strong, as it has been, by a large —— continues to be strong, as it has been, bya large —— by continues to be strong, as it has been, by a large —— by or large in many parts of the united states,

thatis many parts of the united states, that is going to play into his favour and be something he can run with all the way to election day. his approval ratings are low. some polls suggest he is in trouble. you guess it depends on the democrat selected to fight against him? he has never been over 50% popularity at any point either when he was a candidate or president of the united states. what he had in 2016 was a democratic candidate who was also significantly unpopular, even among corners of her own democratic party and certainly along republicans, highly unpopular. he had a perfect storm in a cup of confluence of factors that allowed him to win on election day and it could be a very different case this time around. poll numbers are a snapshot in time, they are here today, gone tomorrow. poll numbers are not heartening or

donald trump at this stage in the game showing he has a lot of ground to make up if he is going to continue this run of success he has had a ballot box. thank you very much for that. my pleasure. let's get some of the day's other news. patrick shanahan, who's been acting us defence secretary since january, has withdrawn. there've been accusations and counter—accusations of family violence. mr shanahan said a painful episode had been dredged up during the confirmation process, and he wanted to protect his children from reliving it. it's the longest time the us has been without a confirmed secretary of defence. the german chancellor angela merkel has insisted she is doing "very well" despite visibly shaking during an appearance with the ukranian president in berlin. she seemed to be struggling to stand as she listened to national anthems during the military honours on his arrival. afterwards she said she was dehydrated and felt much better after a drink of water. a former uefa president is being questioned by french anti—corru ption investigators over the award of the 2022 world cup to qatar.

michel platini was head of european football's governing body until he was banned in 2015 for ethics breaches. he denies any wrongdoing. an earthquake, magnitude 6.4, has struck off japan's western coastline, triggering an evacuation from some coastal areas. there are no reports of serious damage of injuries, although the tremor was felt more than 300 kilometres away in tokyo. in a live bbc tv debate, the five men still in the race to become the next british prime minister have clashed on brexit and whether the uk can realistically leave by the current deadline of the end of october. the former brexit secretary dominic raab was eliminated earlier, in the latest round of voting. 0ur political editor laura kuenssberg reports. he can't hide in the wings any more. microphone on... here we go, there we go. time to talk. thank you very much.

nervous? they all should be. this is nothing less than a public job interview for the biggest role in the land. job number one for all of them, how to clean up the brexit mess. can you guarantee that you will be able to get your brexit plan through the parliament by october 31? we must come out on the 315t of october because otherwise i'm afraid we face a catastrophic loss of confidence in politics. you sometimes have extra time in football matches in order to slot home the winner. my view is the most important thing is to win for britain and that means getting out, honouring the vote you gave. if there was a prospect, if we were nearly there, then i would take a bit longer because the conservative party is the party of business, the party of the union, we're the party of hope, and i would want to avoid the disruption of no deal. i do respectfully disagree with jeremy and michael on this because we've got to learn from our mistakes. one of the mistakes we've made so far is by having this sort of flexible deadline.

if you don't have a deadline, you do not concentrate minds. there's only one door out of this, which is through parliament. i would say to all these people on the platform who voted for the deal, take the shock of the european elections, let's get on with it, let's vote it through, let's get it done. but we've run into that door three times already, rory. we've to have a different route out. we can't simply re—present the same cold porridge for a fourth time. this is about all of our future but the past is never far away. but the worry i have about boris‘ position, we fought together on the leave campaign, boris joined me on that campaign so we both believe it in our heart, but my worry is that, boris, if we got to october 31 and we were so close to getting that deal over the line, would you at that point say, michael, we're almost there... crosstalk. i share, i share, i share, i share michael's... questioner: i haven't heard a guarantee, can you just give me a guarantee it was october 315t? i think that october 31 is eminently feasible. no, that's not a guarantee.

is that your date? can anyone on the stage guarantee yet? crosstalk. can you just raise your hand if there is a guarantee... a cacophony of promises, no guarantees and not much impressed the questioner, worried about leaving without a deal. carmela, are you reassured with what you've heard this evening? i'm not reassured at all. no—one can give a real answer. i'm really concerned about the future for my children. there are, though, other huge decisions and other huge disagreements too. would they all, as the frontrunner promised, cut taxes for higher earners? i think it's very sensible to have an ambition to raise... an ambition? ..the higher rate of tax for middle income earners. ididn't understand... i think that is wrong. i went into politics to help the very poorest in our society. i would focus on tax cuts for working people through the basic rate of tax. i would like to see everyone in this

country be able to earn the first £1,000 every month without any income tax or national insurance because that would lighten the load. i'm going to be very straight with people. i don't think this is the time to be cutting taxes. because i'm not thinking of promises for the next 15 days, i'm thinking of the next 15 years. rory, you're completely out of touch. you just did not answer my question. it's nothing to do with brexit, it's about tax cuts. the favourites wanted to appear to agree for once, rather than stir trouble. i agree strongly with both with saj and withjeremy. did the others deliberately go after rory stewart who was the outsider? and borisjohnson, of course, faced questions on his loose talk about nazanin zaghari—ratcliffe, the british woman held in prison in iran. i have deep sympathy, clearly, for nazanin and herfamily. in that case it didn't, i think, make any difference. but what of accusations laid at the tory party's door that they are prejudiced against muslims, and borisjohnson casually offensive

with his language? do the candidates agree that words have consequences? insofar as my words have given offence over the last 20 or 30 years when i've been a journalist, people have taken those words out of my articles and escalated them, of course i am sorry for the offence that they have caused. they did, in 60 minutes, all manage to agree on something. sajid javid, you've said you'd be happy to open up the conservative party to an independent investigation of allegations of islamophobia. would you like to commit to that? yes, i would. do you all agree, guys? shall we have an external investigation of the conservative party into islamophobia? absolutely, go for it. stamp it out. they all agree. rory, do you agree? excellent, they agree. none of the five walks away having imploded their campaigns tonight. they are in theory, of course, all on the same side. despite the hugs, not for now. laura kuenssberg, bbc news, westminster. much more to come for you on bbc

news, including this: restored to its former glory, the theatre at the palace of fontainebleau is reborn after 150 yea rs. there was a bomb in the city centre. a code word known to be one used by the ira was given. army bomb experts were examining a suspect van when there was a huge explosion. the south african parliament has destroyed the foundation of apartheid by abolishing the population registration act, which for a0 years forcibly classified each citizen according to race. germany's parliament, the bundestag, has voted by a narrow majority to move the seat government from bonn to berlin. berliners celebrated into the night but the decision was greeted with shock in bonn. just a day old and the royal baby is tonight sleeping in his cot at home. early this evening the new prince was taken by his mother and father to their apartments in kensington palace. the real focus today was valentina tereshkova, the world's first woman cosmonaut.

what do you think of the russian woman in space? i think it's a wonderful achievement and i think we might be able to persuade the wife it would be a good idea if i could to get her to go up there for a little while. this is bbc world news. the latest headlines: president trump launches his 2020 re—election campaign in orlando in florida with a promise to, as he put it, keep america great. here in the uk, the remaining five candidates to lead the governing conservative party and the country have clashed over brexit in a tv debate. now a second special report from china's remote western province of xinjiang. the bbc has gained rare access to the secure facilities thought to be holding more than a million muslims, and to religious sites and senior islamic officials. the authorities are trying to refute allegations that, in the name of combatting extremism, they are wiping

out religious belief. here is our china correspondentjohn sudworth. at the id kah mosque, xinjiang's largest, china's supremacy over faith is being made clear — from the flag fluttering on the roof, to the clean—shaven faces below. inside, though, the government—approved imam denies that long beards are now banned in xinjiang. translation: chinese citizens have religious freedom. it's a part of that freedom to choose whether to have beards or not. the locked and deserted homes tell a different story. hundreds of thousands of uighurs, kazakhs and other muslim minorities have disappeared, and even mild expressions of belief are now forbidden. so here it is in black and white, a notice telling people living

in this village that certain religious practices are banned. at this point here, at number ten, it says that the wearing of long beards for young men is not to be allowed. and there is this — right across the region, mosques are being destroyed. over the past two years, in cities, towns and villages, dozens of religious sites, once clearly visible on satellite images, have been turned into patches of bare earth. china's case is laid out in gruesome detail in this exhibition, designed to show that xinjiang has suffered years of separatist violence. and it hopes that by giving us access, including to some of the secure facilities for muslims that it calls schools, such policies will be seen as restrained and reasonable. but this is the gatehouse

to the id kah mosque. its distinctive shadow shows it was still standing in late 2017. now, it's gone, overwhelmed by the surrounding commercial development. work is still under way when we visit, with construction machinery on the spot where the gatehouse once stood. nearby, traditional uighur neighbourhoods are being demolished too. the old homes are visible in this image from two years ago. just a few months later, whole swathes have disappeared. this patch of land encapsulates perfectly the two driving forces of modern china — political stability and economic development. there is no doubting that these neighbourhoods were poor, but by demolishing them, by repressing the faith of those

who lived in them, and by forcing hundreds of thousands of them into re—education, the concern is that a whole history and culture are being wiped out. in 2015, we filmed the crowds, young and old, turning up to pray at the id kah mosque. four years on, this is the scene just before prayer time. inside, a few elderly men gather in silence. isn't the truth that what we've just seen is proof that china has suffocated islam in this region? translation: it's true that a few years ago there were many more people, but nowadays, the government is creating jobs. people are busy making money. so, naturally, fewer come to pray. until recently, this place was the vibrant heart of a deeply devout society. now, there ims almost no—one left.

john sudworth, bbc news, xinjiang. at least 83 people have died since saturday as a blistering heatwave sweeps the indian state of bihar. the north—eastern state is experiencing the second—longest heatwave on record. at least 180 lives have been lost. temperatures have gone over a0 celsius in many places across bihar on tuesday. and water is short across many parts of india, including the capital, delhi, as ramzan karmali reports. delhi, and yet another day of extreme heat. people here are doing their best to keep cool, but that is proving harder each day. this is india's second—longest heatwave on record, 32 days long. lives are being lost due to lack of drinking water in many places. translation: you have to be in line early in the morning.

otherwise, you will not get anything anymore. often enough, many go empty—handed. translation: i have never experienced anything like it. it breaks all records. only rain can save us, but it does not come. and that rain is late, 11 days late. monsoon has been delayed because of huge climate change effect, and with summers, your water bodies are being — because the source of water is being depleted. the worst—affected region is to the east of delhi, in the state of bihar. hundreds of been taken to hospitals and treated for heatstroke caused by prolonged exposure to sun or physical exertion and high temperatures. the death toll in the state is rising, with the temperatures in some places over seven degrees above average. there is little relief. schools and colleges are closed until the end of the week, and many markets across bihar remain

closed during the daytime, but it may not be until the end of next week that many parts of india will see any relief from the deadly heat. ramzan karmali, bbc news. in france, a very special theatre has reopened. it has not been used for nearly 150 years. it was built at the legendary fontainebleau palace during the reign of napoleon iii. it has taken 12 years of careful restoration to bring it back to life. the bbc‘s tim allman reports. palace of fontainebleau is as much a pa rt palace of fontainebleau is as much a part of the history of france as versailles and the elysees. kings lived here, it was a symbol of opulence, decadence, absolute luxury. 0ne opulence, decadence, absolute luxury. one of the most impressive rooms was this grand theatre, now finally restored. ornate gold, the finest of silks, around 80% of the original materials were used.

translation: all that has been preserved is all that can be seen. that was the most important thing for us. the furniture, for example, was taken to an outdoor workshop. the carpets were removed for cleaning and then restored, and then we intervened in areas that were not visible. the theatre was built at the urging of napoleon iii's wife, eugenie. but it was only used a handful of times before the emperor was captured during the franco—prussian war. was captured during the franco-prussian war. translation: we must imagine that, when this place was created, it was only used very, very briefly. in the second empire fell, and the palace closed its doors. it was completely forgotten until the museum was created, but the theatre was forgotten about. until the museum was created, but the theatre was forgotten aboutm was a sizeable gift from the abu dhabi royal family that finally prompted the restoration. it is thought the room is too fragile to

be used for any major performances, but some small recitals may take place. the theatre at fontainebleau is reborn. just finally, some much less cheerful pictures, heart wrenching pictures, in fact, cheerful pictures, heart wrenching pictures, infact, a cheerful pictures, heart wrenching pictures, in fact, a starving and exhausted polar bear from pictures, in fact, a starving and exhausted polar bearfrom siberia has wandered miles from her normal home and habitat and given people in an industrial town quite a surprise. it is thought she is weak, ill and undernourished. the team will arrive on wednesday to decide what is best to do. sad to say this is likely to become a much more familiar scene in the future. there is much more on that and all our stories anytime on the bbc website. and you can get in touch with me and most of the team on twitter. i'm @bbcmikeembley.

hello there, good morning. we still got some rain around, still got the potential for some thunderstorms as well. we got this warm and humid air coming up from biscay, together with the storm clouds that we had earlier on moving across the south—east of england and east anglia, and this is the main area that continues to be at risk of some thunderstorms well into wednesday. some torrential bursts of rain and gusty winds as well. there is one area of storms moving away into the north sea, so we could see more developing late morning and into the afternoon. again, towards the south—east of england and east anglia, may be some patchy rain for lincolnshire and through the midlands, but further west it will be turning drier and brighter with some sunshine, and for scotland and

northern ireland there will be some sunny spells and some showers. and temperatures on wednesday similar to those of tuesday. so some rain for the tennis at some rain again for royal ascot. but thursday, four ladies day, probably dry, and certainly on friday the weather is improving. the heat and humidity in the storms are getting pushed away into the near continent as that weather front leaves our shores, and instead we are introducing fresh air around that area of low pressure. and over night into thursday, towards the north—west, closer to that low, that is where we will see most of the showers. clear skies for england and wales, it will feel cool and fresh overnight. there will be the promise of some sunshine and dry weather to start with an thursday. the showers are going temperature across from wales in the south—west of england. probably the drier, sunniest weather likely to be across the north—west of england. there will be scattered showers across northern ireland and some frequent and heavy showers for scotland. those temperatures again 16 to 20 degrees. as we head towards the end of the week, the signs of this area of the week, the signs of this area

of high pressure building up from the south. but across northern most parts of scotland, we are closer still to that area of low pressure, so here we are going to find some more showers. a bit breezy as well. but away from here, while we will see the cloud building up after a sunny start, it is probably going to stay dry with them spells of sunshine. those temperatures aren't really changing very much at all over the next few days, still stuck at around 16— 20 degrees. as we head into the weekend, however, it should get one everywhere. and a decent start to the weekend, i think as we headed into sunday we will start to see the weather changing, with some rain beginning to put in from the west.

the president trump has launched his campaignfor four more years in the white house. he railed at length against hillary clinton, and what he called the fake news media, and said his supporters believed that a nation must care for its own citizens first. his election slogan for 2020: "keep america great". here in the uk, the five candidates still in the race to become britain's next prime minister — and leader of the conservative party have clashed over brexit in a noisy tv debate. conservative members of parliament will vote again on wednesday to reduce the candidates further. the world health organisation has issued a warning about the global spread of measles. it says the huge amount of misinformation about vaccines shared online — in particular on social media —

is damaging the fight against the disease. now it's time for panorama. personal debt is on the rise. it is just easy, easy money. and there are so many ways to borrow. ijune lending stream, i took out £510 with lending stream and a quickquid loan extension, 166. but up to 8.3 million people are not able to page and it does not matter but up to 8.3 million people are not able to repay and it does not matter where the money came from, if you cannot afford it it can have the same devastating consequences. i was depressed and taking time off work. i'm going to travel the country to meet some of the people

at the sharp end.
