held a special goverment meeting on the lunar new year public holiday, where he warned that the spread of the virus is accelerating. a nationwide ban on the sale of wildlife has been imposed. it's believed the outbreak stemmed from the illegal sale of animals at a wuhan fish market. elsewhere, the us has announced that staff at its wuhan consulate will be evacuated on a special flight on tuesday. and here the foreign office has warned against travel to hubei province, where the virus began, and urged britons there to leave if they can. simonjones has this report. this is the reality of life around hubei province, where coronavirus was first detected. checkpoints with warnings that if you enter, you may not be allowed to leave. in wuhan, not one but two new hospitals are to be built. the first will be ready within days to house 1,000 patients. private vehicles are to be banned from parts of the city centre

to curb the movement of people. 0ne visiting academic from cardiff says she is stranded with no idea of what to do. i am disappointed at the absolute silence on the issue of how stranded people are going to get home. it seems that maybe the british government at the moment has either a lack of concern or a lack of planning, i'm not sure. here in london, the foreign office now advises against all travel to hubei province. it says british nationals should follow the advice of chinese authorities and leave if they are able to do so. it insists the safety and security of british nationals is always its top priority. in the uk, s1 people have been given the all—clear after being tested for the virus. the risk to the public is still classed as low. but in china, the president was able offer little reassurance to his people.

the spread is accelerating, he warned, at a specially convened government meeting. translation: and it seems the contagious or the spreading ability of the virus is getting stronger. of course, we will need more clinical data and materials to reach a conclusion. in response to the prevention and control of the disease, shanghai disneyland is temporarily closed. many tourist sites have been shut and lunar new year celebrations restricted. in wuhan, extra medical staff are being brought in, but both residents and visitors alike have no idea how long the lockdown will last, adding to a sense of concern.

we can speak to ttwo british citizens who are in wuhan, sophie and jason moved there in october to teach english there. thank you very much for being with us, sophie ist of all, how has this outbreak of coronavirus affected you? well, we have been housebound now forffour days, we haven't left our apartment. we have had to stock up on food and water, and if we do go out, we have to wear a mask, it is the law to wear a mask outside, but all transportation has been stopped, so evenif transportation has been stopped, so even if you want to do go anywhere, there are no taxis, no cars, no trains, no aeroplanes, so we are on lockdown pretty much. colour wine in lockdown, jason, if you could leave the city, would you leave at this stage? at this moment in time we do just want to get out. we have got a lot of friends who managed to get out before the lockdown, and they

are not allowed back in, and they seem are not allowed back in, and they seem to have got the better end of the deal, rather than us. i gather you live quite near to the market where it is thought that the outbreak of coronavirus began. yes, so we outbreak of coronavirus began. yes, so we live really where the seafood market was, where it is suspected that it broke out, so we ist heard about the outbreak of the virus of the sist of december, so new year's eve, and since then it has gradually got worse. jason, how nervous are you? how apprehensive are you? because it is obviously a virus that is pretty dangerous, it has killed 56 people we know in china, and it has now spread to other countries. it is getting, like a more scary by the day, especially as we don't hear that much. i went to the hospital la st that much. i went to the hospital last weekjust for a checkup, and everyone there was in full body

suits, masks, it is like a scene out ofa suits, masks, it is like a scene out of a film, it is very surreal at the moment. hmm. is your temptationjust to stay in your apartment because it is dangerous to go outside, or are you getting cabin fever there? we are getting cabin feedback, yes, but we know it is much safer to stay indoors whilst we can, so we are just staying put and playing a waiting game until we hear anything else. jason, from what you have seen, what you make of the way the chinese authorities have handled this? are they being quite open about it? we are finding out most of oui’ about it? we are finding out most of our information from friends on we chat through messaging, and there are a lot of rumours, so we get told to ignore misinformation and wait for official statements, but they are few and far between. is there much about it on the chinese state media, orare

much about it on the chinese state media, or are you just getting information from people you know? there are news outlet reports about it, but i think we kind ofjust go with what we hear from our friends and family as well, and just try and trust our instincts of what to do, but we're just waiting on information that we can get at the moment. and have you had any contact from the british government, from the foreign office or anybody like that? way e-mail to the embassy today, but we haven't received anything back, i imagine they are very busy at the moment. we tried to ring the home office, but they are closed, so we are going to ring them tomorrow to try and get in touch with the home office. you have tried to stock up on supplies, jason, but you are reluctant to go out shopping, but you do need food and drink in. yeah, we have got enough food to last another week. we went

to the shops the other day, and all the fresh food and produce had gone, and we can't really go out to a big supermarket any soon because we are not allowed to get the metro, a taxi, we would have to go somewhere walking distance. when you go out and about, what is the seen light, sophie? describe what the city is like. so we went to walmart, and it was manic, because i think everyone was manic, because i think everyone was the same idea of stockpiling food, and we went to the pharmacy to stock up on the masks to protect ourselves, and they were running out of stock quite quickly. so it is eitheri of stock quite quickly. so it is either i extreme of stock quite quickly. so it is eitheri extreme or the other, eitheri extreme or the other, either chaos or a ghost town. so it is really sad, because we both love the city, it is a great place to be, it is sad seeing it deteriorate over the past few weeks. are you able to talk to your family back home and relatives and so on, jason? yeah, we

have been in contact with everyone back home daily, but we only get in so back home daily, but we only get in so much information, so it is all quite broken up, constantly refreshing the news websites, because that is the only place we can get them, no—i was contacting us. can get them, no—i was contacting us. do you feel, sophie, for the people of the city of the people of china? this is obviously a horrible experience they are going through, they have had things like this before with the sars epidemic, nerve racking for you and chinese people in the surrounding areas.|j racking for you and chinese people in the surrounding areas. i really feel for the chinese people, obviously they had the sars outbreak in 2013 obviously they had the sars outbreak in 201s and it has happened again. we might be able to get out, but this is their reality, they don't have anywhere to go, this is their home, so they have to kind of rebuild of their home, and they are

building ttwo new hospitals, they are trying to deal with situations, but we have a lot of chinese co—workers and colleagues and families, so we really feel for them because they have to deal with these, they don't have anywhere else to go. come out and, jason, i mean, if you did leave, i suppose you would have mixed feelings about the people that you would be leaving behind? yeah, definitely. like, i think if the opportunity came to leave, it would be there for a reason, we can't actually go outside at the moment, so it is not the best place to stay, but not everyone has got the opportunity, which doesn't seem got the opportunity, which doesn't seem entirely fair. and this has been a huge experience for you, to go to china, to teach english, i mean, this is kind of ruining your time there, isn't it? tell a get out well, we literally graduated university in july, and well, we literally graduated university injuly, and we came in 0ctober, so we wanted to travel and

explore this amazing culture in china, and up until now it has been a great experience, but u nfortu nately a great experience, but unfortunately this is carried have tainted our experience a little bit. but i would love to stay and for the situation to resolve itself, but whilst it is not safe, i don't really know what the future will entail. so for the moment you will stay put in the flat for as long as you can? yeah! pretty much! a very good luck to both of you, thank you so good luck to both of you, thank you so much for taking the time to talk to us. both graduate from nottingham university teaching english in wuhan, thank you very much and good luck. thank you, bye! let's turn our attention to some of the day's other news. families affected by the grenfell tower disaster have welcomed the resignation of a member of the inquiry panel appointed by boris johnson last month.

the engineer stood down after being linked to the charitable arm of the company which supplied the tower block's cladding. campaigners had been threatening to boycott the inquiry which starts this week. we can speak now to the grenfell housing caseworker at the north kensington law centre, who gives legal advice to people affected by the grenfell disaster. thank you very much for being with us, what is your reaction to this news? it is definitely positive news, ben. most importantly it is a relief of the anxiety that members of the community had that there was a potential conflict of interest involved. let's just bear in mind a few facts, the enquiry has already ruled that the panels were the main cause for the spread of the fire. arconic‘s lawyers will give their opening statement on tuesday, and

benita mehra has already acknowledged that she has made what she called a regrettable oversight that she had not stepped down sooner than this. the thing aboutjustice is that it is notjust about getting to the truth of what happened, and nobody is really raising doubts about the fact that she wants to help the enquiry, but there will a lwa ys help the enquiry, but there will always be questions hanging over the fa ct of always be questions hanging over the fact of that she was chair of a company that received a very large sum of money from the company that created the panels that caused the spread of the fire and the loss of life. so you feel it was a mistake of the government to a pointer in the 1st place and for her to accept that appointment? — to appoint her. i think everyone can agree that this raises concerns about the government's process and the terms of reference by which they appoint panellist members. this was

uncovered by grenfell united and the guardian newspaper. surely the government must have known about it, if they didn't, then that is a question in itself, and if they did, what kind of question is does that raise about how they assess whether somebody is suitable to be on such a position at an enquiry like this? where do you feel it is going, and do you think it is ultimately going to give you and all the victims of the grenfell disaster they kind of a nswe i’s the grenfell disaster they kind of answers that they need and that they have been looking for false along? the report from phase1 have been looking for false along? the report from phase 1 was positive in that it demonstrated that the enquiry team are rigourous enough to go into the facts, they are not afraid to make bold judgements and assessments, so i think that moving into phase 2, there is an air of

cautious optimism that the enquiry is going to progress. i mean, as i have said, the phase1 report has made the finding that the panels we re made the finding that the panels were the main cause of the spread of the fire, that is setting the tone for phase 2. good to talk to, spike, spy question from the kensington law centre, thank you very much indeed. — spike weston. at the death toll from the coronavirus in china rises to 56. a member of the grenfell tower enquiry panel has resigned over links with the firm that supplied the tablet‘s deadly cladding. s1 people are dead after a powerful earthquake in eastern turkey, more than 1600 have been injured.

all the latest sport for you with ben. roger federer is on course to join the likes of novak djkovic and ashleigh barty in the quarter—finals of the australian open, john watson has been a cross at all, the men's singles 1st, bring us up to speed. yeah, roger federer on the cusp of making another australian open quarter—final, 1 breakup in the 11th set, chasing what could be a 7th australian open title this year, and as things stand on the cusp of a place in the quarter—finals. earlier on today we saw novak djkovic breeze through his match against diego schwartzman, another straight sets win for the defending champion, such is his dominance at the australian open he has only lost s matches in the last 10 years here, he loves playing on these hard courts, and just goes to show once again why he could be the man to beat in the

men's singles this year. come remarkable story, that 1. coco mania ended this year, 1 step too far for coco gauff, huge expectations on his shoulders, butjust 15 coco gauff, huge expectations on his shoulders, but just 15 years coco gauff, huge expectations on his shoulders, butjust 15 years old and after impressive victories over naomi 0saka after impressive victories over naomi osaka and venus williams, she couldn't come through this 1 despite taking the 1st set in the match. surely a grand slam champion in the making, no doubt, hoping to reach what would have been her 1st grand slam quarter—final. ash barty is into the quarter—finals, the home favourite, many hoping that she can go on and win the title this year. if she did so, she would be the 1st australian to win in the singles in

42 years, what an achievement that would be, and let's not forget it is australia day today as well. petra kvitova is also through, there ttwo will meet in the next round, a tantalising prospect, as is the big match tomorrow, rafa nadal against nick kyrgios, you will not want to miss that 1. john watson, thank you very much. after bowling south africa out for 18s, england's batsman adding to their considerable lead in johannesburg, joe root elected not to make south africa go out to bat, sacked rowley and tom sibley have pushed the touring side onto 56— 1. great to see him back playing cricket in general, he has had a very tough couple of years injury wise, he has made some changes to

his bowling action, i believe he has extended his run—up, and he looks really good, really fit, he looks like he is enjoying his cricket again, you know, a fantastic character, great guy, as i said, just pleased to see him back. i1 o'clock kick—off at the etihad stadium manchester city housed fulham. pep guardiola's side are the defending champions and have not lost a home cup tie under the spaniard. phil foden starts for the home side. that is on bbc1 with buildup from 12:a5. and before we 90, buildup from 12:a5. and before we go, something that caught our eye on social media, a south korean tae kwon do athlete, you can guess what happens next, 10 feet up in the eye, he manages to land on his feet as well.

pretty impressive! ben, thank you very much indeed. a cabinet minister has said it is his gut feeling that hs2 should go ahead. the brexit secretary described the project is a key pa rt secretary described the project is a key part of the government's levelling up agenda. ministers are currently mulling over whether to go ahead with the high—speed line, and the decision is expected in the coming weeks. i talked to peter saull about the ins and outs of hs2. lots of speculation about how much it would cost to go ahead with it, how much it would cost to cancel it, and it is the main topic of conversation among mps in westminster at the moment, a huge project, the biggest infrastructure project in europe, and steve barclay, the brexit secretary, not the transport secretary, not the chancellor of the exchequer, but someone who sits around the cabinet table anyway, this is what he had to say on andrew marr this morning. we have a strong commitment to levelling up all parts of the united

kingdom, high speed 2 is a key part of that, notjust kingdom, high speed 2 is a key part of that, not just from speed kingdom, high speed 2 is a key part of that, notjust from speed but more from a capacity point of view in the line, and that is a clear commitment we have given the north. gut feeling, yes or no? yes. so i think that is actually the furthest any cabinet minister has gone in recent months about actually whether the line will be given the go—ahead by the prime minister in the coming weeks. now, steve barclay is possibly not going to be in thisjob for too much longer, we will be leaving the european union at the end of the week, so there will be no need for a brexit secretary, and he may feel that he can speak more freely now that is the case. his constituency in north—east cambridgeshire is not really affected by the planned route either, so maybe he feels it is something he needs to speak out about more. he talks about the levelling up agenda, a huge part of what this government says it wants to achieve, so how does the prime minister squares that agenda with cancelling what is the biggest infrastructure project in europe?

it is a hugely tricky decision for him, but there are several newly elected conservative mps in the midlands and the north of england to a deeply sceptical about it, increasingly worried about the spiralling costs. we will wait and see what the review into this actually finds. we have seen a couple of leaked versions of the 0gilvy report, that is due out, again, in the coming weeks, but also some of the advisors that borisjohnson has in downing street are very sceptical about the project too, so he will be mulling this over in the next few days. we understand he will have a meeting with the chancellor and the transport secretary to make a final decision on it. downing street says the prime minister will make that decision shortly. stephen barclay has also been talking about brexit itself, the commemorations on brexit day,

this coming friday. yes, and we have the first images of the commemorative coin with the simple inscription on it, peace, prosperity and friendship with all nations, along with the date of the s1st of january, no mention of the b word on it, a positive message about britain's changing place in the world. a few loose ends to tie up over the course of the next week, there will be a vote in the european parliament to approve the brexit withdrawal agreement, the final hurdle in the way of it actually coming into effect at 11 o'clock on friday night, and there will be events to commemorate it, including on downing street, the prime minister will address the nation, and there is a party planned on parliament square led by leading brexiteers. so an historic moment, really, coming up for our country, although not a lot will change overnight because we will still be signed up to eu rules until the end of this year while the next, you know, ourfuture relationship

with the european union is negotiated, and that really is the next part of the story, and that is what steve barclay was talking about today on andrew marr, and he said that there would be a document coming out in the coming weeks so that businesses have a better idea of what the government is hoping to achieve. we're going to publish our objectives for the negotiation, and we will set that out. now the key issue... when abouts will that happen? in due course, after the s1st. so there will be a speech from the prime minister after the s1st setting that out. but the key issue is that we will have control of our rules. we will not be a rule taker, we will not diverge for the sake of diverging, we start from a position of alignment. but the key opportunity is we will be able to set our standards, high standards on workers' rights, on the environment rights, on the environment, on state aid, as part of that trade policy. so we have talked about hs2 and brexit, we are also talking about the labour leadership, where are we with that?

we heard from the united general secretary, len mccluskey, a very powerfulfigure within the labour movement, labour's largest financial backer, and on friday they officially endorsed rebecca long—bailey to be the successor to jeremy corbyn. she is seen in some circles as the continuity coffee candidate, they carry on coffee candidate, but len mccluskey denied that was the case, saying she was very much her own person. rebecca long— bailey is absolutely brilliant. she was brilliant on the day, very, very good. i think she is brave, courageous, her capabilities are beyond doubt, and i think she's the one that can actually unite the party and take a message to, not only our heartlands, which we need to win back, but to the rest of our nation. she's somebody who believes in lots of the radical policies that have been developed over the years,

but she has something else as well. she wants to talk to the aspirational views of ordinary people. the backing of unite effectively means rebecca long—bailey will be on the final ballot that is sent to members, joining lisa nandy and sir keir starmer, who have already reached that threshold. emily thornberry, the 11th candidate in the race, still struggling to get enough support. we will see if she manages to do that. rusty in eastern turkey are continuing to search for survivors ofa continuing to search for survivors of a powerful earthquake. rescuers. 45 survivors have been rescued from

the rubble so far, but it is feared there may be many others trapped beneath. you are watching bbc news, a weather forecast now with tomasz schafernaker. after a week are very settled weather across the uk, not necessarily sunny but settled, things are changing now, and it has turned quite wet across western parts of the uk, rain for a time, now it is spreading to other parts of the uk, so in any1 place probably not lasting for too long. this is what it looks like around roundabout lunchtime, you can see the rain across central and more eastern areas, where as in the west at this stage it looks as though it is already going to be turning clearer. through the call stop tonight, the weatherford moves away, then sky is clear, expecting wintry showers for a time, so the early morning rises may encounter some

wintry weather across the northern hills particularly, but for most of us hills particularly, but for most of us mandates looking like a bright date with on and off showers. bye— bye. date with on and off showers. bye—bye. — monday is looking.

good afternoon. the government has said it is looking at all options to help british people leave the areas of china. the united states is flying its staff out of the area with the disease emerged. the chinese authorities have stepped up travel restrictions and banned the sale of wildlife as they try to ban

the spread of the virus. 0ur correspondent reports. warnings echo through the city of 11 million, almost deserted. 0nly medical staff free to travel. checkpoints ring the city, leaving the zone is not an option. hospitals stretched to capacity. foreign nationals unable to get home. the us and japanese governments plan to evacuate citizens but some british travellers say they are getting no clear guidance. the government is saying that people should leave if they can but then the uk government is aware now that all the transport links are closed. so i find it a little bit surprising that we have been totally that we can when there is no possible route. all the transport links have been closed down. the home secretary says all options are being considered. in light of

the urgency of the situation and invite be so we are working with the chinese authorities, the world health organization, public health england to look at actually what is going on and to ensure that we are doing our utmost to stop the virus coming from the united kingdom and obviously becoming a widespread problem. chinese health officials revealed more about the virus which has killed over 50 people, spreading to humans from animals. it is contagious during incubation with no symptoms. that intu bation contagious during incubation with no symptoms. that intubation can last up symptoms. that intubation can last up to two weeks. as a result, all wildlife sales are being banned. but there is evidence of the illness has already spread abroad. in france, three passengers from china are known to have been infected. in hong kong, with five cases, as a precaution the authorities even close to disneyland. every part of daily life affected by the fear of a

virus which knows no borders. they speak to our correspondent who joins us now speak to our correspondent who joins us now from hong kong where the authorities have declared an emergency because of the spread of the virus. this is a virus that is spreading with alarming speed. that is right, ben. i mean, the statistics and predictions as to what is going to happen in the coming days are quite frightening. now, we should remember that this virus appears to have a fairly low mortality rate of around s% so it is not as serious as the virus back in 2002 that had a much higher mortality rate but this virus can spread much more quickly. they are saying in china that there are 2000 cases so far discovered. a study done by scientists in britain has revealed there may be more than that. there may be between 4000 9000

cases which have not been detected yet. those same scientists in the uk at imperial college are predicting that by the end of next week, by the 4th of february, in alone, there could be 200,000 cases. that gives you an idea of how fast this virus is now likely to spend. thank you. families of people died in the grenfell tower fire. there are fresh concerns about the process after an enquiry panel

member resigned had caused serious concern to the families. i am confident that had i continued in my role at the enquiry i would have approached my work with complete independence and impartiality. however, i recognise and respect the depth of feeling about my appointment. the grendel united group welcomed the resignation but accused the government of failing to carry out basic checks before appointing her. it had a new panellist with

expertise in community relations must be found urgently. a murder investigation has begun after a footballer died after being attacked on a night out. he was found unconscious in nottinghamshire in the early hours of friday morning. the 25—year—old suffered a fractured skull and died in hospital. a man has been arrested. the government has given its clearest indication yet that the vhs to high—speed rail project will go ahead. formal review of the new line from london to birmingham and the north is taking place after concern over rising costs. stephen barclay said the rail link will be a vital pa rt said the rail link will be a vital part of uk's transport network. we have a strong commitment to link all parts of the united kingdom and high speed two is a key part of that more from a capacity point of view.

that is very clear commitment we have given the north. gut feeling, yes or no? yes. yes, gut feeling yes. let's get the thoughts of our political correspondent. this is the clearest indication yet that hst will go ahead? what is noticeable about what steve barclay had to say this morning is that up until this point ministers have been at pains not to give any idea which way they are going to go on hst. he had the brexit secretary, his colleagues have been waiting to see what happens with that review. with the prime minister. in consultation with the transport secretary and the chancellor. so is it not clear what insight steve barclay has. as brexit secretary he

downing street says the prime minister will be making his mind up shortly. thank you. cricket, and england are well on top on day three of the final test against south africa in johannesburg. of the final test against south africa injohannesburg. they are currently adding to their big first innings lead. this is billy cooper's last test. this player is playing his last test after playing 16 years for south africa. at times like this

they throw the ball to ben stokes. the highlights belonged to mark wood. this bill was so fast it not only bold, it broke one of his bales. he had five wickets to go with it. south africa 18s all out. with the lead still 200 runs england could make south africa bat again put up and said they decided to have ago put up and said they decided to have a go themselves.

they were looking at my hand and already i had got them... this is a typical maths lesson for year twos in alicia's class. even though she is profoundly deaf, she teaches at a mainstream school using british sign language and lipreading. she has just received a national award for her outstanding teaching methods. itjust breaks it down for them visually.

so today... it's notjust for maths, it helps the skills to grow. we have to say, good morning, look at each other during the register. their friends looked at them. saying good morning to each other, eye contact. alicia's is not the only class that uses british sign language at this school. every single pupil learns it. we are going to have a little peek at the zebras, a year 5 class, and see what they are up to. it is very rare for all children in a uk school to learn british sign language. initially there were some reservations from some parents when she started. however, i think when they see how

amazing she is and the progress of the children, and how quickly they pick up the different signs, and for a lot of the children now, they have learned sign language for a couple of years, so they have already got some of that knowledge as well. and then there are other adults in the classroom, supporting different children and supporting across the whole classroom, and they see that, actually, it's a team effort as well, and everybody is supporting and working together for the best of the children. it's my favourite thing to do at school! it makes me feel happy. if you learn how to sign, you can communicate with deaf people. alicia started as a teaching assistant at a special needs school before training as a teacher. anybody thinking about becoming a teacher, think about it and do it. because children need more role models. and anybody thinking, you can't do it, you can.

now time for a look at all the developments in the world of technology, click. three, two, one, zero. getting into space is an expensive, dangerous, highly complicated business, where hundreds of thousands of precision—made parts all have to work together perfectly. if they don't. ..

but as the race back to space hots up, commercial ventures are looking for simpler, cheaper, quicker alternatives to building spacecraft. and here in la, ifound a startup trying to solve all of those problems in the unlikeliest of ways — by sd printing rockets. this is relativity space. existing rocket bits are not sd printed. what is the advantage of sd printing? a lot of it, from our perspective, is flexibility. traditionally, factories are made of tonnes of fixed tooling. it's then very expensive, very hard to change, then where you have to retooling factory in order to make a new product or even change a product slightly. for us, we can change all of that in software. so it's digitising the manufacturing process and providing flexibility, where, if you push new code to the printers and the hardware on the factory floor,

you can actually make an entirely different product without changing anything in hardware. after a stint at spacex, jordan formed relativity space with his friend and ex—blue origin engineer tim ellis. the two twentysomethings realised that sd printing could help in several ways. because it builds up objects layer by layer, it can produce complicated structures out ofjust one part. also, much of the manufacturing can be done autonomously, which leads to a rather remarkable aim. the team wants to send robots to mars which can then build rockets on the surface. and that means that the astronauts who eventually land there will have a way of getting home. it's both better, cheaper, faster. it's going to actually evolve more quickly than other technologies and we'll launch factories to mars, actually build things like housing,
