results has been delayed to check the figures are accurate. there are eleven hopefuls for the democratic nomination. a good performance in iowa provides important campaign momentum and often helps a candidate secure the party's nomination. let's go live to des moines, iowa and join the bbc‘s katty kay and christian fraser. what more do we know about this delay? it's an almighty mess! i've never seen anything quite like it coming out of iowa. the democratic party seems to have lost control of this process. it's a complicated system that they have set up where 1600 different locations around they have set up where1600 different locations around the state each have two report three different numbers, and there are mixed reports about what is going on. do they have to tally all of those numbers by hand? as some of the technology not working? whatever has happened, it is causing an awful lot of frustration here. one person

who was clearly very happy about this however is president trump. has campaign has put out a statement, democrats are stewing in a caucus method of their own creation with this lobbyist train wreck and history. it will be natural for people to doubt the fairness of the process and these other people who want to run our entire healthcare system. so clearly he is making some kind of hay out of this. for democrats this was supposed to be the big exciting kickoff to their 2020 presidential election campaign and right now it is just looking like a real fiasco of a democratic process. just explained to us why there is so much attention on this vote in iowa with yellow iowa is important because it is the first states that votes. that is frankly why it matters. the candidates will have meant much of their time campaigning over the past year here in iowa, meeting people in small farm villages, and small communities, you really do get

to meet the people. i always love coming to iowa, i love the caucus process. it's fun, engaged, people are very excited, the candidate come here a lot and you get to meet them. they have also spent quite a lot of money here, some $60 million. and then, if you win iowa, it gets you a lot of attention. the press talks about the fact of who one iowa. with a joe biden, was a bernie sanders, so traditionally iowa matters for that. this time around, the story out of iowa is not going to be who one. the story is going to be why couldn't the democratic party doa couldn't the democratic party do a betterjob? how strong is the correlation between whoever wins iowa winning the democratic party nomination itself? historically and a democratic party, very strong correlation. not so much on the republican side. this is because the republicans are

caucusing as well. they have already had their caucus had tonight and they have overwhelmingly chosen donald trump as their candidate. in past years, some republicans have one and not gone on to win the nomination be pretty much for the democrat dominic democrats, they do go on to win the nomination, the exception was bill clinton and that is because an iowa and was running and he was a very popular iowa senator so there wasn't much point campaigning against him, but otherwise this should be a good predictor. hillary clinton one iowa, barack 0bama dead, but this time around, i don't think that candidate, whoever it finally turns out to be, is going to get much attention at all because then tomorrow we have the president's state of the union address and the impeachment trial is carrying on with a vote on wednesday. all right, katty kay there for

us all right, katty kay there for us in iowa. and anthony zurcher joins me now from bernie sanders' campaign rally. what sort of sense are you getting off the mood there? the bernie sanders campaign came in today thinking they had a good chance of winning the iowa caucuses. the polls showed them ahead, sometimes by a co mforta ble ahead, sometimes by a comfortable margin, so they we re comfortable margin, so they were expecting a victory celebration here tonight and quite honestly that was the speech that bernie sanders gave. he initially prefaced it saying that the results went on yet but when they come and he expected it to be a very, very good night and then he launched into what, by all accounts, sounded like the speech he wrote earlier today for a victory. he talked about this being the beginning of the m4 donald trump, all of the normal points that he likes to talk about, income inequality, healthcare, taxing the rich, the establishment lined up against him, so if you were expecting something unusual from bernie sanders because of these unusual circumstances, thatis these unusual circumstances, that is not what he delivered.

and then in terms of the result, if it does go on bernie sanders' favour, what does that do in terms of the direction it ta kes do in terms of the direction it takes the democratic party?” think it would be very good news for bernie sanders to get this when under his belt. he lost iowa caucuses by a very small margin four years ago. he looks to be in good shape and the primary, candidates who have won, gerald ford, al gore, john kerry, all of them went on to win the party's nomination so to win the party's nomination so he would have had a lot of momentum going into the whole raft of states that begins weighing and after that. super tuesday, we see california and texas. there was a feeling among the bernie sanders supporters that i spoke with here at campaign stops

yesterday and saturday, that they were poised to become the front runner in the democratic race for the nomination if they w011 oui’. race for the nomination if they won our. now of race for the nomination if they w011 oui’. now of course race for the nomination if they won our. now of course it is all thrown into question. i have a feeling they are going to still claim victory here, they are still going to think that they are poised for a success that they are poised for a success despite the fact that the results are taking a little longer to come in. when you look at the demographic of those voting in iowa, would it bea those voting in iowa, would it be a political earthquake? would it be seen as that if bernie sanders as the outsider, the further left—wing candidates were to win it, or does the demographic there tend to lend itself more to his favour? the iowa democratic party is the more white, more liberal, older, so a liberal demographic certainly helps bernie sanders. he is going to have to win in southern states and other states that have a

more diverse tomography than an iowa. in 2016, what happened was he came very close in iowa, he won new hampshire in a landslide and then he went to other states that were more diverse and that is where hillary clinton's firewall kicked in because she did very well with black voters. that is something thatjoe biden is carrying on in places like south carolina and across the south, so will bernie sanders be able to change that sort of a dynamic this time around where he wasn't able to and 2016? there are some indications that he is doing better in his hispanic outreach and a place like nevada, but thejury is and a place like nevada, but the jury is still out, by and large stopping the test will come later but to have that kind of momentum from an iowa victory, i think that would be key for him. is there a chance that once we eventually get the result, that we see candidates potentially drop out at this

stage, or not? it depends on what the results come out as. amy klobuchar, a senator from minnesota, she is relying on a very strong result here. she is running low on money, she has put a lot of resources into iowa, she is not doing as well nationally in the polling. she needs iowa as a springboard and honestlyjoe biden, there were some indications that he may have a less than stellar performance here in iowa and if he doesn't finish in the top two or three, if he doesn't look strong here... he's not going to drop out, but he has owned many questions compared to elizabath warren and bernie sanders and pete buttigieg. also, if he doesn't do well, it raises questions of whether he is the proper standard there for the democratic party. if he struggles, i think a lot of voters may start looking around to see if there was someone, anyone else who can top bernie sanders. if bernie sanders does well here, if he does well in

new hampshire, he is going to ta ke new hampshire, he is going to take a lot of incoming fire from the democratic establishment who are going to be desperate to look for somebody to stop him, because many of him as an outsider, someone many of him as an outsider, someone who is not a member of the democratic party for much of his career, and a view that asa of his career, and a view that as a threat to win the election against donald trump, but if he gets into the presidency, to be a threat to the democratic establishment, kind of in the way donald trump was able to remake the republican establishment when he slipped in despite that establishment lining up against him during that republican primary in 2016. 0k, many thanks indeed. as we were just saying, we are waiting to hear the result from iowa delayed by technical problems. not entirely sure what is causing the delay. let's speak to chris buckler.

is there any sense of the cause of the delay there? elizabath warren on stayed behind me, seeming very neat, but if you talk to people who have been campaigning for her, there is no doubt that there is a great deal of anger and frustration about the way all of this has been handled. you take a look at the different statements and i'm sure you've talked about about this, ben, but you have on one hand the democratic party saying as far as they are concerned, this was not a problem, this was about quality checks for data, trying to look at it in that way. a statement from joe biden‘s campaign making very clear that as far as he is concerned, this was a problem with the app that was being used to report the details. and the telephone system that was a backup plan, thatis system that was a backup plan, that is also having problems as well and it leaves you in this remarkable moment where you

have candidate onstage, yes, taking selfies, but also some making victory speeches, and for this big night for the democrats, they are trying to explain this mess. we did receive a speech from elizabath warren on which she concentrated on president donald trump. she didn't talk about this problem, she tried to avoid this whole issue, but at the same time, you imagine there is just a at the same time, you imagine there isjust a great at the same time, you imagine there is just a great deal of frustration with that campaign as much as any others about the way this has been handled. 0ne interesting thing that she did say during this speech was that as far as she was concerned, it was too close to call. be that as an indication that they have got some information about the voting, and they might well chair, but i suspect the democratic party doesn't feel it has an awful lot to chair about. indeed chris, it is easy to get carried away and had the chairs and think, have they heard something that we

haven't? but indeed we were hearing chairs from the bernie sanders campaign as well. if it turns out to be a close result, and there is this issue around the system of the tallying or the system of the tallying or the reporting of results, do you get the sense that there will be questions and challenges over the outcome, or do you think it is not going to go to that? the democratic party has said that the integrity of the result is in this, and that is why they are making the checks. but if it is as close as elizabath warren has suggested it might be, this isa has suggested it might be, this is a difficult a—way fight. we have always known that, between elizabath warren, bernie sanders, joe biden, and pete buttigieg, and you get the impression that the campaigns will be asking questions if the results do not go in their favour. that doesn't mean it is going to go further than that

but what it has done is tarnish this system and remember, this year the democrats will vote to reveal more information than ever before. they plan to reveal details of the first vote, and then what is a second vote, and then what is a second vote, and then finally the numbers of delegates that will represent each candidate as they went to that national convention. instead, they will be left being able to reveal no result, on the big night for the democratic party, when they have the chance to show off some of the front to challenge donald trump for the election, and instead, we have the trump campaign putting up statements that just called campaign putting up statements thatjust called this a train wreck, and indeed, donald trump of course is due to give his state of the union speech in 2a hours time. all of the democratic party that hope to get the media attention is now going to find themselves with comment after comment that suggests that they have been in charge of a mess, and i would be very surprised if mr trump

doesn't make some comments about it in the next 2a hours time. thanks very much indeed. we will of course bring you that result as soon as we get it. the delays are ongoing in the iowa caucus, but we are keeping across that. stay with us on bbc news. still to come: hitting the right note. the choir of young women who escaped the atrocities committed by the islamic state. this is the moment that millions in iran had been waiting for. after his long years in exile, the first hesitant steps of ayatollah khomeini on iranian soil. south africa's white government has offered its black opponents concessions unparalleled in the history of apartheid. the ban on the african national congress is lifted immediately, and the anc leader, nelson mandela, is to be set free unconditionally.

is confirmed in hong kong. let's stay with that now. there are now over 20,000 confirmed cases of coronavirus worldwide, and 425 people have died from the illness, the vast majority in china. the authorities there are struggling with the scale of the outbreak, despite a huge push to build new hospitals in record time. and we have heard in the last few hours that hong kong has reported its first death from the coronavirus, which originated in the chinese city of wuhan. 0ur corresponded robin brant joins us now from shanghai. do we have any more details about the death in hong kong at the moment? well, we know this man's age. he was 39. it's not clear at this stage whether he had any underlying health issues which may have increased

his vulnerability to this infection. we are told that he travelled to wuhan on 21 january on a high speed train and return to hong kong a few days later. his mother, a p pa re ntly days later. his mother, apparently in her early 70s, has also contracted the virus. she, though, according to the hong kong authorities, did not visit wuhan. so the first death in hong kong. we can add that to one fatality as well in the philippines two days ago. the total now stands at 425, according to official figures from the chinese government, and yet again, as we have been discussing almost daily now, there is a double—digit percentage increase every 2a hours, so it would seem. the death toll of about 18% on yesterday's figures, and the number of confirmed cases, as well, as you said, that is just over 20,000 now, that is up i just over 20%. so it would seem

this trend continues consistently, day by day. and in terms of the efforts to contain it, robin, we were speaking about 2k hours ago about the fact there is going to be this staggered and to the lunar new year holiday. have the authorities given any more information, any steer on that yet? well, this country's premier, li keqiang, who is kind of leading the task force in charge of this, said during a meeting several days ago now that different provinces would be given the authority to, you know, enforce their own extensions to the holiday as they saw fit. i mean, hubei, which is the epicentre of the whole thing, nothing in terms of work, school is going to resume their until at the very earliest the weekend of 14th february, and we are seeing other provinces enact similar extensions to the holiday. i mean, here in shanghai, today

and yesterday would usually be and yesterday would usually be a period of a mass exodus of people, migrant workers coming back after a two, three week break. it is a bit more busy out there in terms of the centre of the city where i am broadcasting from at the moment, but it is far from what you expect. a few shops open, the food delivery drivers doing good business, that's about it. there is a trickle of people returning, but nothing like what you would expect. so even here, 1000 kilometres away from the epicentre of this outbreak, people aren't returning or people aren't returning or people aren't returning or people are just staying at home forfear, of course, of spreading or contracting virus. thank you very much for the update. —— contracting this virus. a choir of young women who escaped atrocities committed by the islamic state group is visiting london this week to perform. the yazidi girls‘ choir was created in the displaced people's camps of northern iraq.

the choir was brought together by charity amar international to help people living in camps to overcome psychological trauma. david sillito reports. if you pass them on the streets, you really wouldn't give them a second glance. a group of cheerful and rather glamorous young women doing a bit of sightseeing. but what you don't see are the horrors they have endured. translation: i was nine years old at the time when isis attacked sinjar. i don't know anything about where my father and mother are, nor about my brother or his five children. the choir was only formed a couple of months ago. the women are yazidis, they are from the sinjar mountains of northern iraq, a religious minority that suffered appalling persecution.

many of their songs are their own stories of kidnap, torture and rape at the hands of isis. it is almost impossible to comprehend what some of these women have gone through, and this musical project, well, it's an attempt to save a culture, but it's also therapy. translation: when isis attacked sinjar, they kidnapped me and my brother and my sister.|j sinjar, they kidnapped me and my brother and my sister. i am a yazidi survivor. i was 14 years old when isis attacked out years old when isis attacked our home. translation: when isis attacked, they kidnapped me and my family. isis soldiers came and chose some girls and took them away. then they sold

me to one of them who was from turkey. and this is the world they grew up in, the small yazidi community. their musical traditions go back thousands of yea rs. traditions go back thousands of years. nothing is written down, and there are just 16 official musicians left. 0ne and there are just 16 official musicians left. one reason they are here is to deposit at 0xford's bodleian library a record of this endangered musical culture, before it is too late. the yazidi people have been through a terrible time. there are only 16 left of these people who are allowed to record music. this is about preserving and recording the music around the year, so we are recording the whole year's music and depositing it in the bodleian but more than anything, the music is a way to cope with experiences no—one should face stop it is a really good thing, i enjoy and ifeel good thing, i enjoy and ifeel good when i play music with girls in this group, and i make

new friends. really it is good for us. thank you. 0ur talking point today is about smartphones, after an industry report found half of 10—year—olds in the uk have one of these, a smartphone. i was asking you whether or how you limit children's screen time on their devices. should you limit them? one viewer their devices. should you limit them ? 0ne viewer says their devices. should you limit them? one viewer says i would love to know why parents think a ten—year—old needs a cellphone. another says it is new technology that will help to limit their screen time, embedded systems and apps. and this one from natalie says limit their screen time? no, they shouldn't have one. i was happy with a colouring book at

the age of ten. so was i, natalie, except i could never keep it within the lines. stay with us here on bbc news. hello. 0urfairly hello. 0ur fairly unsettled speu hello. 0ur fairly unsettled spell of weather continues through tuesday. 0ut there at the moment, we have got some strong winds and some fairly chilly conditions as well. in fa ct, chilly conditions as well. in fact, through the early hours of tuesday we could well see some travel disruption due to a combination of severe gales and also some icy stretches and wintry showers, particularly across scotland and northern england. you can see lots of isobars on the map showing the strength of the wind, and we've got low pressure that's slowly clearing out into the north sea. but certainly first thing tuesday morning, temperatures close to freezing for many of us, a degree or two above freezing and most of our towns and cities, but could be a bit below freezing in the countryside. and take a look at their wind gusts we are expecting, up to about 45,

perhaps 55 mph widely across scotla nd perhaps 55 mph widely across scotland and northern ireland, the pennines, 55 mph possible here, and watch out for those icy stretches. windy further south across england and wales. so tuesday looks like a day of blustery showers, and there will be a little bit of sunshine on offer as well. so through the day, then, you can see the extent of the shower particularly for eastern scotla nd particularly for eastern scotland and eastern england. those showers mostly falling as rain buta those showers mostly falling as rain but a bit of wintering us over the highest ground. more sunshine developing, i think, by tuesday afternoon, and those showers will gradually ease away, so showers will gradually ease away, so a showers will gradually ease away, so a slowly improving picture. temperatures only between about eight to 10 degrees on tuesday, and you will notice it will feel colder we've got those brisk north—westerly winds around as well. eventually we will lose the showers as this area of high pressure builds through the west through tuesday night and on into wednesday. so that will quieten the weather down as we look towards the middle pa rt as we look towards the middle part of the week. still the odd shower around late on tuesday, initially around the east coast, and then later in the night some more cloud and a few showers across the north of

scotland. but under those clear skies, with lighter winds, it could be pretty chilly first thing on wednesday morning, with temperatures around about freezing. so some frost and also some mist and fog possible, particularly across the southern half of england and wales. that should clear away through the day. on wednesday, for most of us, less windy certainly compared to tuesday. still quite cloudy and damp across the north—west of scotland, and temperatures fairly cool, around seven to nine degrees for most of us on tuesday. as high—pressure on through thursday and friday, mostly dry, a bit of sunshine by day, do watch out for some mist, frost and some fog overnight. goodbye.
