hello. this is the briefing. i'm ben bland. our top story: the brexit border warning. the uk's own officials warn of customs gridlock if there's no deal. the migrants bound for america. president trump calls the exodus a national emergency. the moment an escalator runs out of control in italy. russian football fans are injured. making it to the mountains. amazon's delivering online shopping to the himalayas, but what does it mean for the people who live there? hello, good to have you with us. a very warm welcome to the programme — briefing you on all you need to know in global news, business and sport.

also in the news, data collection and sharing by mobile apps is "out of control" — that is the warning from researchers at oxford university. nearly 90% of free apps on the google play store apparently share data such as age, gender, and location with google parent company, alphabet. so, do you mind your data being shared by apps? is at the price we paid for free technology? -- is it. let me know. just use the hashtag, #bbcthebriefing. hello. the extent of the chaos if britain crashes out of the european union has been outlined by the country's audit office. it says that 11 of the 12 major projects to change border systems might not be ready in time. that could mean freight companies having to find new routes into europe and a rise in crime. with the march deadline approaching, a brexit deal is yet to be agreed, and tensions among the ruling conservatives are growing. andy verity reports. this is how easily goods flow into

and out of the country now. and this is what might happen to the m20, according to the government and the national audit office, if we get no deal brexit next march. government said if there is no deal, the border will be less than. the priority of the uk's newly enforced borders will be traffic flow and security, but what is less than optimal mean? the national audit office's latest report says there is a risk that 11 out of 12 critical systems needed to manage the border will not to scratch by the date we exit the eu, the 29th of march, and the infrastructure to track goods coming in and out will not be built before them. if the government concentrates on traffic flow in security and customs controls are not enforced, organised criminals may exploit the weakness. the risks and movement to the border will not change it day one, overtime, organised criminals ta ke one, overtime, organised criminals take advantage of any weaknesses in the regime that it perceives. that

could mean that it is easier for goods to be smuggled into the country without paying the customs duty, and it could be easierfor people to be trafficked into the country. the government says it is recruiting around 600 border force offices, but the national audit office points out that in the last three years, border force officer numbers have been cut by 7% and it says there is a risk that new recruits can't be deployed before march. with me is tom stevenson from the investment firm, fidelity international. tom, it seems at this point now that the practical realities of a possible no deal brexit are really being set out in much more detail than we have had before. yeah, absolutely. this is the thai hitting the road, if you like. time is running out, we are now five months away and people are really beginning to look closely at what would actually mean on day one, when the

rules do not apply, the old rules do not apply and the new rules possibly not apply and the new rules possibly not in place. and that is the, that is the difficult bit for businesses planning because you set up your systems for a certain way of doing business and suddenly that stops, no one quite knows what is going to replace it. and it is a phrase that we use time and time again but the business world is not like uncertainty, and the warning that is coming from the uk's audit office seems to be that there is a great deal of uncertainty about whether these border systems, with vast majority of them and the changes required will be ready in time. that's right and some of the numbers which the national audit office have put out are pretty scary, the amounts, just the sheer scale of business that crosses the border, 460 billion pounds worth of imports and exports, 200 million people crossing the border. so the potential for chaos if he

crossing the border. so the potentialfor chaos if he number of customs declaration forms, for example, that need to be filled out is going to rise fivefold from 50 odd million to 250 odd million. if the systems are not in place to cope with that, and it looks like 11 and 12 systems are not going to be ready, then it is quite hard to see how we're going to cope with that. and as you say, businesses hate uncertainty. that is why businesses we re uncertainty. that is why businesses were broadly welcoming of the idea ofan were broadly welcoming of the idea of an extension to the limitation period because the period of status quo is obviously much better, even if you know it is going to change in three years time or two years time, thatis three years time or two years time, that is obviously better than suddenly falling off a cliff edge. we heard in the last two days in the prime minister that the plans, the deal was 95% there. it is one thing to have the principles and the ideals set out and reach agreement on how you are going to do things, but actually, being so close to the deadline, there is not a huge amount

of time now, as we hurtle towards the end of march next year, to actually practically implement things. and that seems to be where the real challenge is going to come, regardless of what deal is done, is actually implementing the term. yeah, absolutely. i mean 95% is as good as 0% really, if you are customs officer at the border, you have a set of rules on what you need to apply and if those rules are not in place, then they are not in place. 95% is sort of meaningless. i heard someone described it as a life—saving operation that was 95% successful, it has got to be 100% ready by the 29th of march audit is not ready. indeed. nice analogy there. thank you very much. we will speak to a little later on we go through the papers as well. thank you. —— speak to you. president trump says the us is facing a national emergency — that's how he's described the caravan of 7000 mostly honduran migrants heading to the southern us border. he's threatened to close

the border completely to halt illegal immigration. the migrants are currently in the town of huixtla in chiapas state, almost 50 kilometres north of the guatemalan border. our correspondent will grant is with them. they have been described as an army, an invasion, as gang members and as an invasion, as gang members and as a legal, but right now, it would be ha rd to a legal, but right now, it would be hard to describe these people as anything other than just exhausted. the days, they had trouble to central america in southern mexico, much of it on foot. it is only now that they have taken a day to recover, to rest weary limbs and treat injuries, and the quietly mourn. one of their number, a young man that, died en route as he fell from a truckie was hitching a lift on. his death is a sign of the risks of migrants on his perilous route north to the united states. it is exactly because of the inherent dangers of this journey, from the dreaded extortion or violence and trafficking gangs to two tragic

accidents on the road, that these people are choosing to travel together in the first place, for safety in numbers. meanwhile, the trump administration has repeated its position on the migrant, that they will not be permitted entry in they will not be permitted entry in the united states under any circumstances. —— through to. the united states under any circumstances. -- through to. united states also has a message for those who are currently part of this ca rava n who are currently part of this caravan or any caravan which follows, you will not be successful at getting into the united states illegally, no matter what. at getting into the united states illegally, no matterwhat. i at getting into the united states illegally, no matter what. i repeat, the caravan will not cost a southern border illegally under any. mexico can border illegally under any. mexico ca n ofte n border illegally under any. mexico can often be a hostile place for migrants from central america, yet one of the most noticeable features around this caravan has been helping local people, whether clothing, food or words of support, the people in this small town in chiapas have tried to lift the morale of those passing through their state. despite the ground covered, the migrants are gathering themselves for the next journey ahead. they still have

around 1000 miles to go before they reach a us port of entry, but between here and there, many say they are simply trusting their faith to god. let's brief you on some of the other main stories making the news this hour. the us state department says it's identified some of the saudi officials responsible for the murder of the journalist, jamal khashoggi. secretary of state mike pompeo said they were from the intelligence services, the royal court, and the foreign ministry. president trump has criticised saudi arabia's handling of the killing, calling it "the worst coverup in history". the italian government is to press ahead with its planned budget, despite its rejection by the european commission. the eu is worried about the impact of higher spending on already high levels of debt in italy — the eurozone's third—biggest economy. the european commission described the budget proposals as a blatant violation of eu fiscal rules. it's given italy three weeks to come up with an alternative.

hurricane willa has made landfall on mexico's pacific coast, with maximum winds of nearly 200 kilometres an hour. forecasters have described the storm as "potentially catastrophic" and have warned of the risk of flash floods and landslides. thousands of people in the south of sinaloa state have moved into shelters. an official visit by the duchess of sussex to a market in fiji has been cut short because of security concerns caused by large crowds. the duchess, who's pregnant, was due to spend 15 minutes meeting stallholders at the venue in the capital suva, but left after about six minutes. royal officials say they weren't expecting the market to be so busy. the authorities in rome are investigating after a metro station escalator collapsed, injuring at least 20 people. it's thought most of those involved were russian football fans. witnesses say some of the supporters were singing and jumping up and down

before the escalator broke. lebo diseko has more. they should've been watching their teams play football. instead, they found themselves in what's been described as a scene like something from the apocalypse. most of the injured were russian fans of cska moscow. they were in town to watch their team's uefa champions league match on tuesday night. repubblica station, in the middle of rome, was packed with people on their way to the game. this video shows the escalator they were on as it suddenly speeds up. travellers on the opposite side try to catch people as they fall. the escalator then comes to an abrupt stop, with what looks like dozens of people crushed at the bottom. firefighters worked for about an hour to try and free people who were trapped between the metal plates of the steps. at least seven were seriously injured. one fan had to have his foot amputated.

translation: the scene that we found was people piled up at the bottom of the escalator. people, one on top of the other, looking for help. two investigations have been launched — one by rome's public prosecutor, the other by atac, the company in charge of the city's public transport system. the task now, says rome's mayor, is to try and understand just how this could have happened. lebo diseko, bbc news. stay with us here on bbc news. still to come on the briefing: we reveal evidence of a vast new network of internment camps in china. it's thought as many as a million muslims are being held inside without trial. an historic moment that many of his victims have waited

for for decades. the former dictator in the dock, older, slimmer, and as he sat down, obedient enough. dawn, and as the sun breaks through the piercing chill of night on the plain outside korem, it lights up a biblicalfamine, now, in the 20th century. the depressing conclusion — in argentina today, it is actually cheaper to paper your walls with money. we've had controversies in the past with great britain. but as good friends, we have always found a good and lasting solution. concorde bows out in style. after almost three decades in service, an aircraft that has enthralled its many admirers for so long taxis home one last time. you're watching the briefing.

our headlines: there are warnings of queues, delays and criminal gang activity at the uk's borders, if britain leaves the european union without a deal. as the migrant caravan heads closer to the us border, donald trump has described it as a national emergency. the bbc has new evidence that china is building a vast network of internment camps for its muslim population in the western region of xinjiang. experts say one facility we've identified, could be one of the biggest detention centres in the world. it's thought as many as a million muslims from the uighur community are being held without trial in xinjiang. china denies the claims, saying it has a programme of "vocational training centres" — needed to combat the threat of terrorism. but the bbc has seen analysis that suggests the number of secure, prison—like facilities in the area has more than doubled in the past two years. accounts of life for individuals inside these places tell

of abuse and humiliation. our china correspondent john sudworth reports from a part of the country where journalists are often prevented from filming. in xinjiang, displays of police might are everywhere. but there's something here they don't want you to see. huge fences all around it, look. behind these blue steel walls, in a former school, is what china calls a vocational training centre. but it looks more like a prison. nearby, relatives queue up to visit. from above, the grim details can be picked out. last year, the school had a football pitch. today, it's covered with what look like accommodation blocks. watchtowers are visible. on a corner, just outside the camp fence, we stop to speak to a family.

what are you guys doing here? some officials try to stop us filming, but another intervenes. "let them speak", she says. i ask who they're visiting. "my dad", he replies. why can't we ask them questions? china denies it is detaining muslims in xinjiang. in response to the allegations, state tv has been showing classrooms of supposedly grateful adults, willingly undergoing reeducation. "without this, i might have followed religious extremists", this woman says. but the bbc has seen new, detailed satellite analysis

of dozens of suspected camps across xinjiang. few of them look much like schools. this giant compound is surrounded by a high wall with 16 watchtowers. we try to approach the site by car. look at this. only to discover that it's being expanded on a massive scale. wow. it's like a city. then the police block our way. if this really is all about education, then why the effort to stop us getting close? the satellite analysts show us a more recent image. it's clear how much the site has grown. but the team is able to show that this one camp is part of something much bigger, by identifying many other similar secure facilities right across xinjiang. plotting their growth over time shows just how fast they're being built.

satellites see beyond what the human eye can see. as the years pass, we have detected that the number of infrastructures being built increases and, most significantly, in the past two years. and prison design experts tell us this could now be one of the biggest detention facilities in the world, holding 11,000 inmates at the very least. xinjiang's main muslim minority are known as the uighurs. now, many of their homes are locked and deserted. sinister official notices on the doors say the missing are being "looked after". "re—education", "vocational training", to use china's euphemisms, suggest something limited and temporary,

but our evidence shows that the camps and prisons being used for that purpose are large—scale and seemingly permanent. the big question then, is where does all of this end? and the history of mass incarcerations, of course, offers some pretty ominous precedents. from a vegetable field to another one of china's new schools, in less than six months, complete with watchtowers. we tried to film one of them. but once again, while trying to get to the truth, we're asked to leave. john sudworth, bbc news, xinjiang. here's our briefing on some of the key events happening later. we begin in brussles at 8gmt, where apple ceo tim cook will deliver the keynote speech at an international conference on data security.

a few hours later in strasbourg france, the european parliament will vote on a new law to forbid the sale of single use plastics in the eu from 2021. and finally in paris, the latest bansky print goes up for auction. will it self—shred like the last one did? we'll have to wait till 6pm gmt to find out. now it's time to get all the latest from the bbc sports centre. hello, i'm tulsen tollett. coming up in your wednesday sport briefing: liverpool and barcelona are in champions league action later. the wta finals continue in singapore. and cristiano ronaldo always has time for his fans even when security are trying to eject them. liverpool forward sadio mane could feature in his side's champions league game with red star belgrade a week after having surgery on a hand injury. mane missed saturday's premier league win at huddersfield after sustaining the injury playing for senegal. jordan henderson and naby keita won't play and reds boss jurgen klopp says the support

at anfield is the key to his side's success. we need to be ready for a really ha rd we need to be ready for a really hard fight, we need to fight for each little square metre of space, or whatever, with all we have, and for that we need our crowd, so that's very, very important. we learned last year, not only what we learnt last year a specially, that atmosphere can make the difference and that's what we have to make sure again. also in action on wednesday are barcelona, the spanish champions are at home to italian side inter. the catalans have scored eight goals in two games in this competition but they're without talisman lionel messi, who's suffered an arm injury. inter have won both their games so it promises to be a pivotal game in group b. it's another big day at the wta finals in singapore on wednesday and it could see a big name on the verge of exiting the competition early in the red group. world numberfour naomi osaka is up against world number two angelique kerber.

the loser of this match would then have to win their last match and rely on things going their way after both suffered defeat in their opening matches. sloane stephens plays kiki bertens in the other match on wednesday with both having won their first matches. in case you missed it, cristiano ronaldo's return to old trafford ended in a 1—0 victory for hisjuventus side over manchester united in the champions league. paolo dybala grabbed the only goal of the game in the first half with ronaldo coming close to scoring after half time only to be denied by a brilliant david de gea save. the italian's remain undefeated in all competitions this season and sit top of group h with united second a further five points back. in the first half they were in control by having a lot of the ball. they managed to have the ball, to hide the ball from us, to frustrate

us, to frustrate our intention to be positive in the game. in the second half, we were more aggressive, a big effort by the boys. holders real madrid got their stuttering season back on track as they head towards this weekend's el classico with barcelona. julen lopetegui's side were 2—1 winners at home to czech side viktoria plzen with karim benzema getting the opener before marcelo grabbed a second and despite a late plzen score it leaves real second in group g on goal difference behind roma. cristiano ronaldo'sjuventus won against manchester united but the portuguese has no shortage of supporters from his time at old trafford and many still want a picture with their hero. and the man who's won the champions league five times is usually happy to oblige with a selfie although this may be one for the scrapbook as he's getting a picture with a fan who security are attempting to eject. it was after the full time whistle and ronaldo was even doing his best to be the diplomat when he realised what was happening to his fans. you can get all the latest sports

news at our website, that's bbc.com/sport. but from me, tulsen tollett, and the rest of the team, that is your wednesday sport briefing. great stuff. the world premiere of the film detailing the rise to fame of freddy mercury, the frontman of the iconic rock band queen, has taken place in london. among those in attendance were the band's surviving members brian may and roger taylor. may said freddy mercury, who died in 1991, would have loved the movie. it's called bohemian rhapsody, and is named after one the band's best known songs. it follows freddy mercury's early career with queen in the 1970s, including his personal struggles with his sexuality and substance abuse. today the talking point we have been

and as long as we're to the south of these weatherfronts, dominated by high pressure, it's going to stay quite mild. once those weather fronts move soputh, so the colder air is going to arrive. fairly quiet—looking day, really, on wednesday. it probably won't be as a windy. i won't be as wet in the northwest of scotland either. just a bit of drizzle here, perhaps into north—west england and north wales over the hills. always more cloud towards the northwest, eastern scotland, eastern england, southern parts of england and south wales seeing the best of the sunshine. temperatures may get as high as 16 or 17 degrees. through the evening and overnight, we'll find a little bit more rain arriving in the northwest of scotland. we will also find some cloud pushing its way down further into england and wales, so it won't be as chilly. those temperatures perhaps no lower than 4, 5, 6 degrees or so and they again pretty mild across the bulk for scotland. this is where we've got some rain in the north of scotland. the far north of scotland actually seeing some breaks in the cloud and perhaps a few showers. the rain really gets going later on in the day in the nortwest of the mainland of scotland.

over the highlands in particular some heavy rain. elsewhere, probably dry to the south. some sunshine. those temperatures easing awayjust a little bit —12—14 degrees. but the really cold air comes behind that rain, which is that cold front there. that's the weather front. that is starting to move southwards overnight and into friday. allows us to draw in the air all the way from the arctic so it is going to feel much colder on friday. there will be quite a bit of sunshine around. but there will be some showers, paticularly down the western side of the uk and then later near the north sea coat. but those temperatures come the afternoon. and 8—9 degrees is going to be fairly typical, struggling to make double figures in southern part of england. high pressure instead of being over the uk is out towards the west so that's why we are drawing down this really cold northerly wind. a significant windchill again across northern half of scotland, where there will be soem wintry showers continuing overnight and into saturday over the hills. probably more showers coming into eastern parts of both england and scotland on saturday. further west, a lot of those showers moving away and probably you will see the best of the sunshine here but cold. 7—9 degrees or so.

it stays pretty cold right the way through the weekend and into the beginning of next week. the winds tending to ease down. some sunshine but also some showers or longer spells of rain. hello. this is the business briefing. i'm ben bland. taking on the trade tensions. with the world's two biggest economies locked in a trade war, canada launches a plan to modernise the rules on global business. making it to the mountains. amazon's delivering online shopping to the himalayas, but what does that mean for the people who live there? and we will keep an eye on the markets. this is a little snapshot for you right now.
