the social media giant, facebook, is under growing pressure to explain the measures it's taking to secure the personal data of its two billion users worldwide. it's facing investigations by the us federal trade commission, the uk's information commissioner, the european parliament and a house of commons committee. it follows allegations that information on millions of facebook‘s users was gathered from the site and used for political purposes by the british firm cambridge analytica. that firm's chief executive, alexander nix, was suspended earlier this evening. our business editor simonjack reports. in the information age, personal data is the new currency and we spend it liberally on social media platforms. how old we are, whether we are in a relationship, what are our political leanings, this can all be gathered and used. cambridge analytica is a company which does exactly that and it is at the centre of a political storm that has rocked one of the biggest companies in the world. it started with an app designed by a british academic that invited

facebook users to do a personality test. 270,000 people downloaded the app, it collected personal information on them, theirfriends, theirfriends‘ friends and so on until it had information on 50 million facebook users. that data was passed to cambridge analytica, who allegedly used it to influence the presidential election in the us, using highly targeted messages, a charge denied by the company. the uk's data watchdog said she had concerns about the company for some time. these allegations are very serious, they came to the attention of our office some months ago. and on the 7th of march, i issued a demand for information from cambridge. they did not comply with that, so now i am moving ahead to seek a warrant so that i can search premises and data. the company worked on donald trump's election campaign and secret filming by channel 4 news shows cambridge analytica's boss

boasting about the role they played in his victory. the company denies any wrongdoing. the company says mr nix's comments did not represent the values of the firm and it has now suspended him pending their own investigation. whether this tiny consultancy was really involved in influencing the us presidential election, there is an old adage, in digital marketing which says if the service you are getting is free, then you are the product. served up to advertisers who are convinced that highly targeted messages constructed around detailed personal information really works. facebook is also right under the microscope. it too denies any wrongdoing.

the us federal trade commission has launched a probe into the company and has the power to levy colossal fines. the company has seen $50 billion wiped off its value in just the last two days. so, could this scandal mark a moment of reckoning for the way we share and companies use our personal data? i think for the first time, things that people suspected have surfaced thanks to the testimony of whistle—blowers. now we are finally seeing that the leaders of these companies are being called to testify in front of parliaments. they are being held to account in the media, analysts in the financial industry are dumping their stock as a vote of no—confidence. this is a real moment where it is going to incentivise change. the facts of our lives are valuable. facebook founder mark zuckerberg has built a fortune out of them. politicians on both sides of the atlantic want him personally to explain how they are used. in a moment we'll talk to north america editorjon sopel in washington, our media editor amol rajan in san francisco but first to simonjack outside cambridge analytica's headquarters. simon, tell us more about the

reaction now during the course of the day. these rather modest offices, the second floor here have become the rather unlike the eye of a storm that has engulfed facebook and drone in the politicians on both sides of the atlantic. when the story broke, cambridge analytica said they had done nothing wrong, that the footage and reporting grossly misrepresented the position of the company, the executives were talking in hypotheticals. they had changed their tune and they are saying that the comments of the firm and he was suspended pending their own investigation. we heard politicians about today, damian collins, said he

wanted to extend an invitation for a mark zuckerberg to appear in person to explain how this information got into the wrong hands. i should say that the company does not deny it worked on the trump election what came by this information, it denies that it use that information in that campaign. 0n the financial markets, a lot of people rapidly friending facebook, its shares have fallen by $50 billion. more than the entire value of the ford motor company. real implications for what is going on in. thank you. and tojon. there are concerns by regulators as well. yes. you're in the position where cambridge analytica are either telling falsehoods, which is not a good look or it is telling the truth, in which case, it could be in a whole heap of trouble with lawmakers here. they claim to have been responsible for the entire digital strategy of the trump

campaign, of the crooked hillary campaign, of the crooked hillary campaign well. leave to one side whether donald trump will accept that cambridge analytica were responsible for the election victory but some of the claims they make about coordinating between the trump campaign and some of what they call, super packs, that are meant to be entirely independent of the campaign, that would breach us electoral la and that could cause problems. then there is mark zuckerberg, if he has been called to come and give evidence, he has a bunker on his estate, i don't think that will protect them from the rout of lawmakers on capitol hill. and to amol rajan... what is the pressure on the company? facebook is facing its biggest crisis since the company was founded in 2004. crisis since the company was founded in 200a. tens of billions wiped from its stock market value, you have the

resignation of a senior figure in the company and the mood here is one of banks and anxiety and investors are getting uppity and talking about rebelling. it has got to be said that the response to this crisis has made things worse. earlier this afternoon, there was a meeting and mark zuckerberg was not there. the chief operating officer was not there. i have just spoken to a senior executive who said that they were taking the time to gather the fa cts were taking the time to gather the facts and when the revelations first came to light, the company said it was not a data breach. it could have been something worse, the mass harvesting of the data of millions

of people without them knowing. this is making people wake up that for all its innovation, facebook is a mass surveillance tool that used to be about selling products which is now selling politics as well and that has implications for western democracy and facebook have not got their head around it. thank you. the royal air force has announced that a member of its red arrows aerobatic team has died in a crash in north wales. the engineer was killed when a hawk jet came down near the raf valley base on anglesey earlier this afternoon. the pilot, who is injured and receiving medical care, managed to eject. there are no details about the cause of the crash, as our wales correspondent sian lloyd reports. the remains of the hawk vastjet, which crashed within minutes of taking off from raf valley. two members of the red arrows display team were on board. plumes of smoke were captured by people walking on the nearby sand dunes. later, confirmation came that a crew member had died. the engineer's family have been informed, and have asked for a 2k hour period of grace before further details are released. a pilot of the aircraft survived the incident and is currently receiving medical care.

an air ambulance arrived within 20 minutes of the tragedy taking place, and fire crews were quickly at the scene. as night fell, the investigation continued. peter glover saw what happened from his nearby caravan. the canopy come off, i saw a chute open, and the plane just hit the ground severely hit the ground, and a massive bang, and a massive bang, then a bowl of smoke. the red arrows aerobatics team are famous for their displays. the two crew members had been training on anglesey, and the jet was returning to its base at raf scampton in lincolnshire, when it came down. we're not expecting any further details to emerge of what happened until well into tomorrow, but tonight, the thoughts of those here and across the service with the families of the two people involved in this crash.

sian lloyd, news, raf valley. twenty—three russian diplomats and their families have left the uk, after they were expelled in the wake of the salisbury poisoning attack. they left on a plane bound for moscow this afternoon, as theresa may chaired a meeting of the national security council. ministers have again accused russia of involvement in the attempted murder of former spy sergei skripal and his daughter yulia, as our diplomatic correspondent james landale reports. this report contains flashing images. it was dubbed ‘expulsion day‘ — the moment russian diplomats and their families began the long journey home from their embassy in london, sent packing after their government was blamed by britain for the nerve agent attack in salisbury. those staying behind gathered outside to hug their colleagues, wave goodbye, and yes, shed the odd tear, as the long cavalcade of coaches and cars left for the airport. in a tweet, the russian ambassador

bade farewell to his colleagues, after what he called ‘the hostile move of the uk government'. at stansted, the ambassador stood at the aircraft steps to shake the hands of the 23 departing diplomats accused by britain of being undeclared intelligence officers. his embassy said that with spouses and children, about 80 people were leaving in total in what's the biggest expulsion of russian diplomats from britain since the cold war. this afternoon, the russian plane carrying its diplomatic cargo finally took off from moscow. finally took off for moscow. this weekend, british diplomats will travel in the opposite direction. today, the foreign secretary boris johnson confirmed that the former russian intelligence officers sergei skripal and his daughter yulia have been in a coma since they were poisoned two weeks ago. morning! what's our next move against the russians? ministers gathered to decide what britain should do next.

russia's already announced that 23 british diplomats must leave moscow by the weekend. in the end, the government decided not to impose further sanctions on russia. it wants to avoid a bilateral tit—for—tat row and instead keep up the european and international pressure on moscow. a task made harder today by the european commission president jean—claude juncker controversially writing to president putin congratulating him on his re—election. james langdale, bbc news in downing street. a two—year—old girl has died after being pulled from a car in the river teifi in west wales. kiara moore was found in the vehicle in the river in the town of cardigan. dyfed—powys police have described her death as a ‘tragic incident‘ —— and say they‘re not looking for anyone else in connection with the case. enter there‘s been a bigger than expected fall in the rate of inflation, the latest figures show that prices rose by 2.7% last month,

compared with 3% injanuary. a small drop in petrol prices and a slower rise in the cost of food were some of the factors cited, as our economics editor, kamal ahmed, explains now. mixing in a new ingredient, after over a year of rising inflation, today better news — the rate is falling, as food costs ease and fuel costs drop. inflation can often start here, firms that make the stuff we buy. if their costs are cut, then prices for us often go the same way. there‘s not many costs that are coming down, but the two things we have identified are distribution costs for us. we‘ve definitely seen those ease off, but also in digital and technology. for millions of people, today‘s fall in inflation brings into sharp focus one of the most important issues facing the uk economy — that income squeeze. prices rising faster than wages, leaving people worse off month by month.

today, a glimmer of hope. with inflation easing and wage rises strengthening, could that income squeeze be coming to an end this year? before 2017, wages were rising faster than prices, meaning that people were slightly better off each month. then last year that reversed, inflation rose quickly following the brexit referendum, which saw a fall in the value of the pound and an increase in the price of imports. now the pound is stronger, the rate of inflation is falling and wages are catching up. could those lines cross in 2018? the impact of the fall in the pound, of course, meant that imported inflation was quite high. that effect is fading. increasingly now we‘re seeing inflation coming from domestic sources. so higher wage growth in particular is driving up costs. inflation risk has not drained away and wage growth will keep minds focused at the bank of england. it‘s signalled that it will raise

interest rates in the next few months to control any future price rises. kamal ahmed, bbc news. a bbc investigation has revealed that rohingya girls as young as 13, who fled myanmar in the past six months, are being trafficked into prostitution in bangledesh. the undercover team filmed traffickers openly offering the girls for sex in cox‘s bazar, the town nearest to the refugee camps, where hundreds of thousands of rohingya muslims now live. the bbc‘s mishal husain has the story. a small city on the bay of bengal, where the main business was tourism, is now the hub for aid agencies working in the nearby refugee camps. but alongside the shop fronts, the beachside bars and the hotels of cox‘s bazar there‘s an open secret. after hearing repeated stories about children trafficked into prostitution, we went in search of the evidence.

0ne14—year—old rohingya girl we met in the camps, and whose identity we‘ve protected, told me what happened to her as she crossed from myanmar into bangladesh. translation: women came with a van, they asked me if i‘d go with them. not long after that, in a building in cox‘s bazar, they brought two boys to me. they showed me a knife and punched me in my tummy and beat me because i wasn‘t cooperating. then the boys raped me. i wasn‘t willing to have sex, but they kept going. we heard other accounts from girls of a similar age. a 13—year—old told me she was lured out of the camp by a woman from within the rohingya community offering her work. with the desperate conditions the refugees are living in,

her family agreed to let her go. translation: she came to my home. we know her. she said, "you‘re not being fed properly, come with me to cox‘s bazar, i will give you a job." when we got there, she put me in a hotel in the morning. by the afternoon, a boy was put in my room. he beat me and raped me. i asked the woman, "why i should do this"? she told me, "if you don‘t do this, i will kill you." after only 48—hours on the ground, our team had identified a number of people offering children for sex. this was one of them, not only boasting about his own collection of women and children, but of a network of traffickers, all of whom had more than ten girls under their control. we had to be careful not to create

a demand and asked for girls who were immediately available. we were offered these three and told they were all rohingyas, aged between 13 and 17. we went to the police and told them what we had found. they agreed to conduct an operation that same evening. 0ur undercover investigator posed as a client who wanted to have sex with children and arranged with the trafficker for the delivery of two young girls to a hotel. bring the girls down here. as we waited, the trafficker sent a scout. 8.00pm, red hoodie. he asked our investigator to go with him, but we needed the trafficker to come to us. he‘s away with the girls.

he appeared to change his mind. we are go, we are go. but when the girls arrived, it was a driver who was with them and who collected the money. how it‘s going? 1a,15,16 and and two for you. ask him, if tonight‘s good, can they get more? we handed over around £140. as soon as the deal was done, the police moved in. come on, girls. hey, come here. the girls were two of those we‘d seen in the photograph. as they were taken aside and into safety, they told us they were 15 and 21 and that their families depended on the money they made from sex work. what the two girls told me here tonight reveals so much about how they and others like them get trapped in the sex industry in cox‘s bazar. they‘ve never been to school and have no idea how they would support themselves without this work. and with the arrival of so many

refugees in the nearby camps, there are even more vulnerable young people for the traffickers to prey upon. childcare professionals and trafficking experts helped us to arrange care for the girls afterwards. the younger one went into the care of social services, but the 21—year—old refused. we handed over all the information we had to the police. but the trafficker is still at large, part of an established network that puts children into sex work here and, as our investigation found, also sends them further afield, to india and nepal. now the presence of a large refugee population, including many unaccompanied children, is providing easy pickings for the traffickers and another danger for the rohingya people. mishal husain, bbc news, bangladesh. the parents of a 6 year—old boy,

with a rare form of epilepsy, say they‘ve been told that a special licence will be granted for their son to use cannabis oil on compassionate grounds to treat his condition. alfie dingley was joined by his family and the actor sir patrick stewart as they handed in a petition at downing street earlier today. his parents say cannabis oil, which is illegal even for medical use in the uk, will help control his seizures. the health secretary, jeremy hunt, has suggested that plans to reform the adult social care system in england will include a cap on the cost of care. mr hunt has set out seven key principles which he says will guide the changes,

acknowledging that patients with conditions such as dementia faced a far greater financial burden than those with other illnesses. the government is due to publish its strategy later this year. 0ur social affairs correspondent, alison holt, reports. 0k, charles? are you going to watch... charles, are you going to watch ginge? the care system in england is a punitive lottery for people like charles major, who has dementia, according to today‘s speech by the health and care secretary. here at woodbury manor in north london, he gets good care, but his wife who used to look after him at home had to fight for the local authority‘s support they needed. they don‘t have funding, enough funding, for everyone. and i think you‘ve got to really get to the state where you‘re at rock bottom before they really take notice of you. here, care staff work alongside nhs nurses to assess the needs of residents. the government sees more integrated services like this as a key principle for the future. it also acknowledges staff need to feel more valued. sometimes ijust get frustrated,

fed up and say, you know, the money is so small. i cannot cope. the pressures that come with an ageing population mean something has to change. by 2026, one in five people in the uk will be 65 and over. by then, more than a million people will have dementia. but by 2020, councils in england estimate there will be a £2.3 billion shortfall in care funding. as the secretary of state set out his principles for a better care system today, he indicated a green paper on funding, due this summer, will contain a cap on care costs to give people more certainty. they want to have a sense that, even if they‘re unlucky enough to get an illness like dementia, which affects one in three over 65s,

it can potentially clean you out of your life savings, people want some security and comfort that that isn‘t going to happen. at the moment, that is what happens. whilst the principles have been broadly welcomed to many in the care sector, they want to know if enough money will be there to fix a system that is struggling. it will only be real if money comes with the principles. he now needs to go and discuss with colleagues in the government the amount of funding needed, both new money and the money that currently may be spent in the nhs that could be better spent in social care. and with the care system already under great strain, the government knows it will be under increasing pressure to make sure that these plans for reform really do lead to change. alison holt, bbc news. the northern white rhino is a species on the brink of extinction following the death of a 45—year—old male in kenya, the last of his kind in the world. his name was sudan, he was put down on monday after his health problems worsened significantly. his daughter and granddaughter are the only female northern white rhinos left. 0ur correspondent, alistair leithead, reports from kenya. and then there were two — the last remaining northern white rhinos on earth, now that the last male, sudan,

has died of old age. a subspecies of rhino ever closer to extension. one is najin, 27—years—old, sudan‘s daughter. the other is fatu, his teenage granddaughter. the last of what was once a great species that roamed central africa. this was sudan, and for the last few years scientists and conservationists have been trying to get him to mate. they even put the 45—year—old on tinder as part of a publicity campaign. there was no other animal quite like him. it highlights first and foremost the fact that human greed and sometimes human activities that are not controlled can drive species to extinction. the last wild northern white rhinos were seen here in garamba national park, in the northern democratic republic of congo, but that was many years ago.

they became extinct in the wild in 2008. well, fatu and najin are now the last two remaining northern white rhinos, and obviously they‘re both females. they‘re here under armed guard 24—hours a day, such is the continuing threat to these animals from poachers. they are now incredibly rare. there are only 30,000 rhinos left on the planet and sudan was unusual for his kind, in that he died of old age. now it‘s up to the scientists and a never before tried fertility treatment in a last gasp effort to save these animals from extinction. alastair leithead, bbc news, in northern kenya. more than 50 years after the beatles were awarded mbes at buckingham palace their drummer, ringo starr, has returned today to receive a knighthood. the musician, who was presented with the honour by the duke

of cambridge, spoke of his shock at being given the award in recognition of his services to music. next month a team of pilots, paramedics and doctors from the london air ambulance will take on the toughest foot race on earth. it‘s called the marathon des sables, and they‘ll be running 150 miles across the sahara desert — six marathons in six days — carrying all their own kit to raise money for the air ambulance charity. and running with them will be former patients and families who owe them their lives in many cases. sophie raworth went to meet them. there are some flashing images in the report. i remember wheels turning across me, and then i don‘t remember the impact as such, but i remember being on the floor, and really panicking because i tried to get up and i couldn‘t move my legs. she was deathly white. she had lost a lot of blood, she looked like she was dying. can you hear me? three years ago, vicky labrecque was cycling to work when she was knocked off her bike by a lorry.

vicky, what we're going to do now is we're going to give you an anaesthetic. her life was saved thanks to a pioneering medical technique carried out at the roadside. so we really need to then crack on and get her into the ambulance and get her to the royal london as quick as we can. i mean, if it hadn‘t been for the air ambulance then i wouldn‘t be here because they‘re the only people that do this procedure and, if that hadn‘t happened, then i would definitely be dead. they managed to save her life, but the surgeon, tom koenig, wasn‘t able to save her leg. now, three years later, he will be part a team of medics and patients heading to the sahara to raise money for the air ambulance. running alongside will be another cyclist, who also owes her life to london air ambulance. i remember it happening. i remember going under the wheel, trying to get the wheel off, trying to speak to the driver afterwards to say sorry, because i thought i was going to die and he would have to live with that. chloe baker, now a doctor, was a medical student
