i'm ben bland in london. the headlines: the race to be britain's next prime minister — the final five candidates to lead the governing conservative party go head to head, with all of them clashing over brexit. none of us wants a no deal outcome. i haven't had anyone on the stage to guarantee anything yet. raise your hand, raise your hand. go to. —— crosstalk. the race for the white house — president trump is about to launch off his 2020 re—election campaign in florida. i'm gary o'donoghue in orlando where huge lines of trump supporters have been queuing all day to see the president.

i'm sharanjit leyl in singapore. also in the programme: a warning that the world is taking an "unacceptable step backwards" in the fight against measles. a special report from the philippines. and a long way from home — how a tired and exhausted polar bear ended up in siberia's industrial waste land. it's 7am in singapore and midnight here in london, where just three hours ago, in a studio a few metres away from where i'm standing now,

the remaining candidates hoping to become the next british prime minister went head to head in a live television debate. the clear favourite remains the former foreign secretary, and arch brexiteer, borisjohnson. but he could still face a fight for the uk's top job. here's the bbc‘s political editor, laura kuenssberg. you can't hide in the wings any more. microphone on. there we go. time to talk. 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 you will be able to get your brexit plan through the parliament by october 31? we must come out on the 315t 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 union and the party of hope. i would want to avoid the disruption of no deal. i do respectfully disagree with michael and jeremy on this because we have got to learn from our mistakes. one of the mistakes we have made so far is by having this flexible deadline. if you don't have a deadline you can't concentrate minds. there is only one door out of this and its parliament. i would say to all these people on the platform — take the shock of the european elections, let's get on with it, let's vote it through and let's get it done. we have run into that door three times already, rory. we have to have a different route out. we can't simply represent 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‘s position, we fought together on the leave campaign and hejoined 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 are almost there... crosstalk. i share michael... i think october 31 is eminently feasible. that's not a guarantee. is that your date? can anyone on the stage guarantee? 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 have heard this evening? i'm not reassured at all. i'm really concerned about the future for my children. no—one can give a real answer.

there are, though, other huge decisions and have the 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 the higher rate of tax for middle income earners. 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 £1000 every month without any income tax or national insurance because it would lighten the load. i will be very straight with people. i don't think this is the time to be cutting taxes. i'm not thinking of promises for the next 15 days, i'm thinking of the next 15 years. rory, you are completely out of touch. you just did not answer my question. it's not brexit, it's about tax cuts. the favourites appeared to agree for once, rather than stir trouble. i agree strongly with sajid and jeremy. 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 her and her family. i don't think that case made any difference. but what of accusations laid at the tory party 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 would 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 we all agree, guys? shall we have an independent enquiry into islamophobia in the conservative party? excellent, they agree. neither of the five candidates walked away having loaded their campaigns tonight. they are, in theory, of course, on the same side. but despite the hugging, not for now. more about that debate of course on our website. but now, let's take a look at some of the day's other news. russia and china have called for restraint and reason between the us and iran. russia says the us should halt actions that could provoke war with iran. here's what the us secretary of state, mike pompeo had to say today. communicating to eran that we are there to deter aggression, president trump does not want war. — make eran. we will continue to project that message. —— iran.

also making news today: 12 people are reported to have been killed in the earthquake which struck south western china on tuesday. rescue teams worked through the night to reach people trapped in collapsed buildings in sichuan province following the magnitude 6 tremor. meanwhile, an earthquake with a magnitude of 6.4 has struck off japan's western coastline, triggering an evacuation from some coastal areas. there are no reports of any serious damage of injuries, although the tremor was felt more than three hundred kilometres away in tokyo. now some heart wrenching pictures of a starving and exhausted polar bear. she's wandered miles from her normal home and habitat, and has given local residents quite a surprise. the bear has been seen walking through the siberian industrial town of norilisk. she's belived to be very ill and weak. experts will arrive on wednesday to access the condition of the bear

and decide its fate. president trump has never really stopped campaigning — but his 2020 re—election campaign will formally launch in couple of hours. he'll take to the stage at a rally in orlando, florida. mr trump actually filed his re—election paperwork just hours after being inaugurated in 2017. let's go to gary o'donoghue at the campaign launch venue at orlando in florida: this is really president trump doing what he does best, at a rally, campaigning. this is his ideal climate stop he doesn't much relish business of winning all that much. this is his comfortable place. he

seems he can't wait to get back on the campaign trail. let me give you one statistic. there are 50a days until the next presidential election. 50a days and here we are at the launch of his 2020 bed. the slogan they are using here tonight is keep america great. based of his, of course, make america great again. the queues are very high, as you would expect from an event like this. when i spoke to them outside, isaid this. when i spoke to them outside, i said look, he is now a politician. he was an outsider, he is now one of them. they said no, no, no, he is not one of them. they still believe in president trump as the great disruptor. i just wonder,

in president trump as the great disruptor. ijust wonder, among his supporters, if they are looking at a scoresheet of his first term, what will count in his favour and what will count in his favour and what will work against him? its incredible noise here. they will look to things like the tax cuts that were brought in and will see that were brought in and will see that as a success. a lot of them pointing to the success of the economy and the growth rate over 3%, low unemployment levels. significantly, decades low, unemployment levels. it is interesting, the president doesn't much want to talk about that stuff. he was once quoted recently as saying the economy is boring. so i'm sure we will hear some of the old themes tonight, the question of immigration, the question of democratic challengers likejoe biden, the question of china, building the wall, all of those things i'm sure will come out again. what will be interesting is whether

there is any new themes, any kind of new ideas, to galvanise his base because in a sense, he has to recreate that excitement, but a sense of insurgency, that got him into the white house in the first place. it is no accident he has chosen florida for this launch, is it? florida is a very important state of the president. he won here backin state of the president. he won here back in 2016. of course, it was really the win here, early on that election night, that altered the whole process of him winning the electoral votes that he needed to get. the fact that florida swung for him, that gave us the indication it was going his way. of course, he has his big resort at mar—a—lago and west palm beach, not far south, to the east of where i am here. and of course, in the mid— term elections, when there was a bit of a wave election for the democrats in terms

of taking back the house, florida really laughed that trend. it kept the governors' mansion and flipped the governors' mansion and flipped the senate. it is no surprise that he is here to do the launch. normality is slowly returning to the streets of hong kong after millions of people marched to protest a controversial law allowing extradition to mainland china. hong kong's chief executive carrie lam says it's unlikely her government will move to enact the bill — but did not withdraw it and has refused calls to resign. let's go live to hong kong and the bbc‘s laura westbrook. we still see people behind you and its just two days after that massive

rally we on sunday. tell us a little bit about carrie lam, the territory's leader, because he —— she faced up to the press, something she faced up to the press, something she hasn't done for a number of days. i have been reporting on this for the last week and while the roads are open and the city has pretty much gone back to normal, what has remained is the level of anger against carrie lam. she hasn't appeared in public since saturday when she announced this bill would be suspended. that wasn't enough to calm people's fears because they worry that it could be reintroduced which is why we saw those massive numbers on sunday, the biggest protests in hong kong's history, and yesterday, carrie lam faced the world's media and publicly apologised. she has admitted her mistakes. she said she wanted to reach out to the city's youth, and she also said there wasn't enough

time in this current term to go through the necessary procedures in consultations to pass this bill. which effectively means that it is dead although she didn't officially say that. she didn't however resign which is what many people have been calling for, and so the organisers of that march on sunday i going to be meeting with the pan— democratic camp which is the opposition camp here in hong kong, to decide their next move. let's go back to our main story, the tory leadership race. so the remaining candidates to be britain's next prime minister have held their first televised debate, but did anyone land a decisive blow or make a fatal mistake? political journalist isabel hardman is the assistant editor of the spectator, a british political magazine. this is her assesssment. candidates talking over one another and being unable to present a clear

plans on brexit. i don't think anyone, including those of us who are political nerds and follow these things very closely, really came away with the sense that there was someone away with the sense that there was someone in that group of five candidates who had an idea that was realistic about how to sort out the brexit mess that this country is in. probably on a sort of slightly lighter note people will remember rory stewart's slightly strange demeanour. he was sort of leaning back at points. he discarded his tie after the second question, which left some of us wondering what he was going to discard over the next few questions, as well, and he was as well the most aggressive of the candidates. he promised he was going to go after borisjohnson and he really did, and he gave the tory membership, who are obviously people that all of these candidates were really broadcasting to, a sense of what a contest between him and boris johnson would really look like, and it would look quite polarising and

it would look quite polarising and it would look quite polarising and it would look quite aggressive. you mentioned going after borisjohnson. the former foreign secretary has been a front runner all along so far in this race. she is there any indication that this debate has moved the dial or narrowed the race in any way? not really for him. i think his team will be happy, largely, with the way he performed. he was quite reserved, particularly compared to rory stewart. actually, he didn't commit any gaps. his question, his answer on the particular question about islamophobia in the conservative party, that was not good. it was very poorly executed. i'm not sure whether he fluffed the lines that he and his team will inevitably have prepared, because he started off by suggesting that it was other people's fault that his column on the brca, where he compared women who wear the burqa to post boxes, that other people had decided to ta ke that other people had decided to take those comments out of context. and then he pointed out that his turkish great—grandfather would have been proud of him for being foreign

secretary, which no—one really cares about, and isn't really evidence that there is no islamophobia in the conservative party. i thought sajid javid had a very good approach to this question, which came from a imam in bristol. sajid javid turned on the other candidates and said would you hold an enquiry into islamophobia in the conservative party, and under the hot campaign lights they all squirmed and said yes. it made it look like he was on top of things rather than being on the defensive. just briefly, from what you have seen so far, who do you think is going to emerge victorious? i think it is still boris johnson's to victorious? i think it is still borisjohnson's to lose. he has been running a very safety first campaign. his team have got an interesting approach to trusting their own candidate and they haven't really led him out of the bunker, as some of the newspapers have been calling it, over the last few days. we will see more of him now as the campaign moves to the conservative party leadership, but i think the campaign is still going to be very safety first.

you are watching newsday on the bbc. still to come on the programme: the world health organization issues a stark warning about the global spread of measles because of misinformation about vaccines. 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 newsday on the bbc. i'm sharanjit leyl in singapore. i'm ben bland in london. our top stories: in britain, the remaining five candidates to lead the governing conservative party and the country have been taking part in a tv debate, dominated by the issue of brexit. president trump heads to florida to kick off his 2020 re—election campaign at a massive rally in orlando. let's take a look at some front pages from around the world. we start with the south china

morning post, which says the chinese president's state visit to north korea is set to be a grand affair. xi jinping's arrival on thursday will inject new impetus into the already close ties between beijing and pyongyang. gulf news in dubai has the story that ex—uefa president michel platini is being questioned by anti—corruption police in france. the former french football captain is being held over the awarding of the 2022 world cup to qatar. finally, the japan times carries a report which highlights the country's problem of an ageing population. the un says japan has the world's lowest ratio of people of working age to those over 65. it is a highly contagious disease for which there is a safe and effective vaccine, yet the world is taking an unacceptable step backwards in the fight against measles, according to the world health organization. it says a wave of misinformation

online has contributed to vaccination rates stalling across the world, resulting in an alarming rise in measles cases. one of the worst affected countries is the philippines, from where our global health correspondent tulip mazumdar reports. this is what can happen when measles takes hold. james hasn't eaten for days, and he has now developed pneumonia. some of these babies are less than six months old, too young to have the measles vaccine. they rely on others around them being immunised, so they don't even come into contact with the disease. in the next ward, two—year—old princess lies limp and exhausted. "first she had a cough",

her grandmother tells me, "then suddenly a severe fever." princess was not immunised. her family were worried vaccines might harm her. we were admitting 30 to 40, and even as high as 80 patients admitted every night. we were so frustrated, disappointed, because the vaccine for measles is given free at the different health centres. much of these recent misconceptions around vaccines centre on the controversial rollout of a new dengue vaccine in 2016. the manufacture of dengvaxia later disclosed that its product posed a risk to some children. some families blamed the vaccine for their children's deaths. investigations are under way, but no link has been proven. health officials say inaccurate and sensationalist information about vaccines in general spread online, resulting in the confidence in all vaccines plummeting. misinformation and fear overtook

evidence and science for many parents deciding whether to vaccinate their children. health facilities and medics can also be difficult to access in these poor, slum areas. there are trust issues, too, so when accurate information wasn't available or wasn't believed, many parents instead listened to rumour and scaremongering online. the infection of misinformation, as the un children agency unicef has called it, can spread as far and fast as a computer virus. this woman bitterly regrets her decision not to vaccinate her two children. her two—year—old daughter and her eight—month—old son died of measles within a week of each other. translation: ijust feel so angry. i shouldn't have listened to the tv and social media. i was afraid, but i should have protected my children. these volunteers are on a mission to restore faith in vaccines among concerned parents, whojust want the best for their children. slowly, the trust in the immunisation programme is getting back.

so now, mothers are visiting the health centres, demanding for the vaccines, because they are afraid for their children. the measles outbreak had slowed dramatically from its peak earlier this year. families in the philippines have paid a high price for the dip in vaccination rates here, but confidence in these life—saving vaccines is returning. tulip mazumdar, bbc news, manila. you have been watching newsday. i'm ben bland in london. and i'm sharanjit leyl in singapore. stay with us to find out what happened when we hit the streets of streets of london, beijing, delhi and singapore to ask what you are doing to reduce plastic waste. and before we go, we would like to leave you with these pictures of the strange undersea worlds filmed by a chinese research vessel. these images were filmed at the floor of the western pacific ocean, not far from the mariana trench, the deepest part of the sea.

we can't tell you what all of the creatures you are looking at are called, because many haven't yet been given a name. quite beautiful, though, aren't they? hello there, good morning. by thursday, the weather should be much more straightforward. but we still got cloud around at the moment, bringing some outbreaks of rain. there are some storms around as well as this warm and humid air pushes its way northwards. that cloud

bringing the rain, this cloud bringing the rain, this cloud bringing the rain, this cloud bringing the storms as well. and they are tending to track their way across the south—east of england and east anglia, and this is the main area at risk of further thunderstorms as we head well into wednesday. there could be some really gusty winds, some hail and some thunder as well. this is the story as we head towards the end of the night. we've got a lot of cloud of england and wales. outbreaks of rain, storms moving away from the south—east of england, pushing across east anglia and into the north sea. things are more straight board for scotland and northern ireland, where we've got sunshine and showers arriving from the north—west. but by late morning and into the afternoon we could see a fresh crop of thundery downpours arriving in the south—east and east anglia, even if few patchy bursts of rain across the midlands and lincolnshire. much brighter further west across england and wales, and those temperatures very similar to what we had on tuesday. so some rain u nfortu nately what we had on tuesday. so some rain unfortunately again for the tennis at queens, and some rain for race—goers at royal ascot. thursday probably drive a ladies day, certainly drier, i think, on friday by then. but it will be feeling a little bit fresher. the humid air ahead of that weather front that's going to push into the near continent, the storms heading away as well, and this fresh air were pulling from the atlantic around that area of low pressure. closer to that area of low pressure. closer to that area of low pressure in the north—west of the uk, this is where we keep showers going over night into thursday. clear skies, cooler, fresher feel for england and wales, but the promise of smelly sunshine. now, some places may stay dry, but

there are some showers heading eastwards from wales in the south—west of england, the driest weather and sunniest weather across northern england. a scattering of showers were northern ireland, some heavy showers across scotland, and again those temperatures 16— 20 degrees. as we head towards the end of the week, were starting to see high pressure building up from the south. but across the northern half of the uk, particularly northern scotland, we are closer to that low pressure. that means some showers will keep going in northern scotland, and it will be quite blustery as well. after a sunny start for many other areas, we are going to find cloud building up, but there is a good chance you will stay dry with them spells of sunshine into the afternoon. and those temperatures really unchanging very much at all over the next few days, 16- 20 much at all over the next few days, 16— 20 degrees. however, over the weekend, it looks like all of us will get warmer. saturday looks mostly dry with some sunshine. things start to change on sunday as we see some rain beginning to arrive in from the west. that's it from me. goodbye.

i'm ben bland with bbc news. our top story: the five conservative candidates vying to be the next british prime minister have clashed in a noisy tv debate. they disagreed over whether a brexit deal could be negotiated before the current deadline at the end of october. they also clashed over a key stumbling block — how to avoid physical checks at the border between northern ireland and the republic of ireland. president trump is about to launch his 2020 re—election campaign at a rally in orlando, florida. and this story is trending on bbc.com. scientists say this picture of a dog—sled team in greenland wading through a lake of melted ice, shows the impact of climate change. that's all. stay with bbc world news. now on bbc news, hardtalk‘s
