international pressure mounts on facebook over allegations about the use of millions of people's data. founder mark zuckerberg has been summoned to parliament to answer questions. it follows allegations that a british firm, cambridge analytica, used data from 50 million facebook members. of course individuals should be careful. of course they should think twice about who they're sharing their information with, but on the other hand it's really up to the companies to get this right and comply with the law. we'll be asking what impact the claims could have on the giant tech firm. also tonight. a red arrows hawk has crashed at an raf base in north wales. two people were on board — it's not yet known if they survived. expelled after the nerve agent attack — a plane carrying 23 russian diplomats leaves britain on its way to moscow. cheaper fuel and food lead to a bigger than expected fall for inflation — it drops to its lowest level since last summer. and on the brink of extinction — the last male northern white rhino in the world has died in kenya.

and coming up on sportsday on bbc news. england scrum half danny care admits they let the fans down after their worst six nations finish. but they're still aiming to win the world cup. good evening and welcome to the bbc news at six. there's growing international pressure on the social media company facebook tonight, over measures it's taking to ensure the security of the personal data of the two billion people who use it around the world. it follows allegations from a whistleblower that information about 50 million of its users has been harvested from the site by the british firm cambridge analytica and used for political purposes. facebook‘s boss, mark zuckerberg, was today ordered to appear before

mps to answer allegations. here's our business editor, simonjack. in the information age personal data is the new currency 5 and we spend it liberally on social media platforms, how old we are, whether we are in a relationship, what our political leanings, this could be gathered an used. cambridge analytica is a company which does exactly that and it is at the centre of a storm that has rocked some of the biggest companies in the world. it starred with an app which invited facebook users to do a personality test, 270,000 downloaded it. it collected personal information on them, theirfriends, theirfriends, friends and so on until it had info on 50 million user, but that data was passed to cambridge analytica, which allegedly used it to influence the presidential election in the us, using 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 march i issued a demand for information to cambridge, they did not comply with that, so now i am moving ahead to seek a warrant so i can search premises and data. separately cambridge analytica executives were veeblingtly filmed by channel 4 on advice on how to influence politicians. —— secretly. cambridge analytica said it has been grossly misrespected. whether this tiny consultancy was involved in inflews the election there is an old adage which says that if the services you are getting are free, then you are the product,

served up to advertisers who are convinced that highly targeted messages constructed round detailed personal information really work. since the scandal broke, facebook has seen £50 billion wiped off its value and the pressure on the company was cranked up today, when the federal trade commission announced it will investigate its handling of customer data. it has the power to levy enormous fines. facebook denied any wrongdoing, could this be a moment of reck cob for the way our data is used? for the first time things that people suspected have surfaced, thanks to the testimony of whistle—blowers, now we are finally seeing the leaders of these companies are being called to testify in front of parliament. analysts are dumping their stock as a vote of no confidence. this is a moment it will incentivise change. the facts of our lives have value. mark zuckerberg

will have the chance to tell mps how safely the information is kept. simonjack, bbc simon jack, bbc news. our north america technology correspondent dave lee is in san francisco. facebook, a huge global company now, the pressure is mowning, how significant a moment is this for them? i think this could be a hugely significant moment for them, indeed for silicon valley in general. the mood here is that the era of tech self regulation may be reaching an end, we nuns the last hour, there has been a meeting at face book with employees but it wasn't chaired by mark zuckerberg or his deputy, we haven't here from either of them since this news broke on friday. internally and externally as we have been hearing they are facing investigations on both sides of the atla ntic investigations on both sides of the atlantic and the impact on the company's value has been to the tune of round $50 billion, so in the

short—term, hugely significant and also as we are learning in the long—term it will have real impact on how this company does its business. thank you. a red arrows jet has crashed at raf valley airbase in anglesey. two members of crew were onboard the hawk aircraft — their condition is unknown. our correspondent sian lloyd is at raf valley. yes, the red arrows hawk crashed round 1.30 this afternoon shortly after take off. it was on its way back to raf scampton which is where the red arrows were based. two people were onboard, currently we don't know anything about their condition. an investigation has already begun here, and this afternoon we have seen a great deal of activity, both in the skies and also on the ground. the air ambulance was called, an emergency ambulance was called, an emergency ambulance was called to the scene and we have seen a number of police

vehicles which have secured the perimeter here of the base. now, later on this evening, we are expecting a statement, but the ministry of defence have said that they would not be speculating about any of the details, or the possible cause. it is far too early days for that. when we get that information we will bring it to 23 russian diplomats and theirfamilies have now left the uk after being expelled by the british government over the salisbury nerve agent attack on a former spy. they left on a plane bound for moscow this afternoon as the prime minister theresa may chaired a meeting with the national security council to decide if further sanctions should be imposed on russia. our diplomatic coreespondent, james landale reports. 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. the embassy released pictures of a reception last friday, in honour of the 23 departing officials accused by britain of being undeclared intelligence officers, forced to swap the attractions of london diplomacy for a new and perhaps different life in moscow. at sunset, the russian ambassador shook the hands of the departing officials, spouses and children, as they boarded the aircraft home. his embassy said in all, about 80 people were leaving, in what is the biggest expulsion of russian diplomats from britain since the cold war. in a tweet, he bade farewell to his colleagues, after what he called ‘the hostile move of the uk government'. morning!

what's our next move against the russians? today, ministers gathered to decide what britain should do next. russia's already announced that 23 british diplomats must leave moscow by the weekend. and the decision was to impose no further sanctions on russia — at least, for now. the government clearly wants to keep up international pressure and not get sucked into a bilateral tit—for—tat row with moscow. today, the foreign secretary, borisjohnson, confirmed that the former russian intelligence officer sergei skripal and his daughter, yulia, have been in a coma since they were poisoned two weeks ago. this afternoon, the russian plane carrying its diplomatic cargo finally took off from moscow. this weekend, british diplomats will travel in the opposite direction. james landale, bbc news. the rate of inflation dropped sharply last month, from3 to 2.7 %. the price of petrol and food played a key part in the fall. economists believe the fall will ease the pressure on the bank

of england to raise interest rates. here's our economics editor, kamal ahmed. mixing in a new ingredient, after over a year of rising inflation, today better news, a fall, 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 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. a bit more upbeat maybe. were people in east london though feeling the effects quite yet? all the necessities you need to live, nothing's cheap — gas, electric. you spend more day—to—day on things that are going up than what you go to buy that's going down. 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, inflation is falling and wages are catching up. inflation risk has not drained away and wage growth will keep mind

focused at the bank. its signalled that it will raise interest rates in the next few months to control any future price rises. kamal ahmed, bbc news. our top story this evening: international pressure mounts on facebook over allegations about the use of millions of people's data. why this air ambulance team is heading to the is a haarwhere for the toughest foot race on earth. coming up on sportsday, on bbc news: we meet the man trying to take anthony joshua's heavyweight titles away. wbo champion joseph parker takes on the british fighter in just under two weeks in cardiff. now, if there's one thing that can really unite motorists and cyclists,

it is potholes and the state of britain's roads. one in five roads is in a poor condition, according to new figures, and local authorities are struggling to fund improvements. the recent snow and cold has certainly not helped. the bbc‘s looked at data for roads — it doesn't include motorways — in england, scotland and wales and found that in england just 5% of them were deemed to be in a poor condition. meanwhile, 10% of the roads in wales are in a bad way. in scotland, more than a third of the roads are of poor quality or in need of inspection. lorna gordon reports from glasgow. cracking, crumbling and potholes. look familiar? you don't have to go far to come across them. as you travel on our roads. well, dreadful, aren't they? potholes everywhere. do you find yourself dodging them much? very much so, especially in the wet. my car and my van we've had broken

springs due to potholes. they're just everywhere, you can't avoid them really. you just keep going over them and hoping you're not on average, about £100 is the damage damage per customer because this one's a bit more exes spencive. expensive. going to be looking probably about £1,000 for the four tyres. many of us, whether in a car or on a bike, will have found ourselves dodging potholes. motor organisations say the recent cold snap will have led to some roads deteriorating further still to the point where the potholes are not just annoying and potentially costly, but increasingly dangerous too. keith ralph has cycled all his life. in january, while commuting through south london, he went over a

pothole, was knocked unconscious and left with several injuries, including a bleed on the brain. when i came to a guy got me to the side of the road and apparently i was unable to remember my name, where i lived or anything. then i got popped into an ambulance and taken to lewisham hospital where i was dealt with quite swiftly. put on painkillers and had the ct scans on my brain, etc. i was there for two—days. from silverstone to suffolk, motorists have been recording the state of the roads and the damage caused to their cars. 0h. across the country, from the centre of leeds to leafy lanes on the norfolk borders, there are now thousands of miles of roads that need fixing. those responsible say they are going as fast as they can, but warn it will cost billions to get them all back into a good state of repair.

lorna gordon, bbc news, glasgow. a two—year—old girl has died after the car she was in plunged into a river in wales. kiara moore was pulled from the vehicle in the river teifi in cardigan. police officers say they're investigating the incident and have appealed for witnesses. from cardigan, tomos morgan reports. kara moore, just two years old, had it not been for the tragic events of yesterday afternoon, she would have been celebrating her third birthday a week today. it's understood that two—year—old kiara was left in the silver mini while a family member went into offices nearby. by the time the family member returned the car car had disappeared. the police we re co nta ct car car had disappeared. the police were contact and a search was under way. they believed the car to be stolen. it transpired that the car was in the river teifljust yards away. the toddler was airlifted to the university hospital of wales in cardiff, but doctors were unable to

revive her. young families in the town today have been paying their own tributes by laying flowers by the river. she was a very lively little girl. very smiley. cheeky little girl. very smiley. cheeky little smile she had all the time. she... her and her little smile she had all the time. she... herand her mum little smile she had all the time. she... her and her mum were always together, always fun days out. and... she had a happy little life. short life, but a happy little life. commenting on facebook, kiara's father thanked the work of the emergency services whilst also paying tribute to his daughter saying she had an "amazing but short life." it's saying she had an "amazing but short life. " it's unclear as saying she had an "amazing but short life." it's unclear as to how the mini came to be in the river teifl as family and friends mourn the loss of young kiara the investigation into exactly what happened continues. tomos morgan, bbc news, cardigan. hundreds of disabled people are to benefit from an increase in funding for a scheme designed to help them into work.

from next month, the maximum grant will rise to £57,000, money designed to pay for support workers and transport costs. our disability news correspondent, nikki fox, has more details. ben has worked at this large accountancy firm for more than 17 years. work is hugely important to me. i always had the goal of having a career, to have a job, to be able to support myself. he has cerebral palsy and needs this specialist wheelchair and his support worker, mohamed, to help him do the things he can't. thank you very much. ben relies on funding through access to work, a government scheme set up to help with extra costs like this. but in 2015 a cap was implemented and because of this ben was denied the funding he needs to replace his ageing wheelchair. you feel that you battle so hard to be able to come to work and work full—time and hold down a job for the length of time that i have done and, in order to be able to do that, you do need support,

and there seems to be a complete lack of support through the imposition of the funding cap and the way that it's managed. could problems like ben's be a thing of the past? today the government has announced an increase to the cap from just over £42,000 to £57,200, twice the average salary. but campaigners say any limit on the amount of money available will have a negative impact, particularly for deaf people. many need multiple interpreters, and that comes at a cost. the best way is to remove the cap altogether. what's most important is that people have access to the employment market regardless of how much that costs. i think a slight raise in the cap, we'll still be facing and dealing with the same situation. there are lots of disabled people and campaigners that feel there shouldn't be a cap at all. would that not be something that you would consider? we've really carefully worked with our stakeholders and i'm confident that this level of support will meet the vast majority

of needs of disabled people, enabling them to get into work, stay in work and make progress in work. so while i am sat at my desk during the day, i can move my feet. without this chair, ben would be unable to work and he's spent thousands of pounds of his own money keeping it going. but the government says it's confident he and many others will now be benefit from the increase. nikki fox, bbc news. a 45—year—old male northern white rhino has died in kenya, he was the last of his kind in the world. sudan was in poor health and was put down on monday after his condition worsened significantly. his daughter and granddaughter are the only female northern white rhinos left, which means that species is now on the brink of extinction. from kenya, alistair leithead reports. 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 are 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. the television and radio personality katie boyle has died aged 91. now our first model is reg, and he's wearing a navy blue suit and a peaked cap. well, no. she appeared in a number of tv shows, but was perhaps best known for presenting the eurovision song contest

for the uk during the ‘60s and ‘705. its paramedics, pilots and doctors save lives across the capital every day. next month a big team from the london air ambulance are taking on the toughest foot race on earth — the marathon des sables. 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. i went to meet them, and a warning, there are some flashing images. 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. joining them is vicky's sister, marie. i'm forever in debt to this charity. what they did for me, vicky and my family is incredible and they do it every day. it's going to be an incredibly emotional experience to be doing this big challenge with a team of people who saved my sister's life, ultimately. running alongside marie and tom 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 when she was knocked off her bike 11 years ago. the pilot who came to rescue her remembers that day vividly. this patient was self—diagnosing herself and she, being a medic of some sort, knew what she thought she'd done, which is is really rare, and we'd never really heard of before. for chloe, just over 15 minutes to get a trauma team service right next to her, i think that makes a massive difference to any patient in that situation. chloe now works alongside the team who saved her, and in three weeks' time they'll all be swapping the london chill for the saharan sun. we will suffer in those seven days, but i think our suffering pales into insignificance when you think about the suffering that our patients suffer. i think from the first step to that very finish line, which we hope, i hope that we will all

pass together, it's going to be emotional. it will be great. it will be great to bring everybody home, and i'm thoroughly looking forward to it. the trauma surgeon tom konig, who's about to set off on a gruelling challenge. time for a look at the weather. here's tomasz schafernaker. different in the sahara. certainly not 45 degrees. today is the first day of astronomical spring. the weather has changed in time wem have milder, i want to emphasise the word "milder" weather for the next few days. tonight it will be pretty chilly. the jetstream is days. tonight it will be pretty chilly. thejetstream is broken up here. that means that things are starting to change in the atmosphere. this side of the atla ntic we atmosphere. this side of the atlantic we are starting to see this strong winds putting in weather systems in our direction. that is a clear side sign that the atmosphere is reversing rather than weather systems from the east, they will

come out of the west. the temperatures will start to rise. relatively compared to what we've had. tonight, lots of clear weather across the country. good touch of frost around, even in city centres first thing in the morning on wednesday. the weather going down hill, the jetstream pushing wednesday. the weather going down hill, thejetstream pushing in weather fronts. from the word go for scotland, northern ireland, pretty cloudy here. rain to the western isles during the course of wednesday. to the south the skies will clear over a little bit. temperatures up to 10 degrees. despite the cloud in belfast it is still up to around 10 celsius i think on wednesday. wednesday into thursday we see this plume of milder aircoming in our thursday we see this plume of milder air coming in our direction. we could get into the low teens depending on how much sunshine we will get. thursday the mildest day out of the lot, not necessarily sunny. we have a weather front bringing rain to belfast, cloudy

skies here. in the east and south it will be dry and brighter. despite the rain in belfast temperatures up to around about 10 degrees. spring has kind of sprung. kind of. thank you. a reminder of our main story: two people were on board. the raf has said an engineer died in the crash. the pilot survived and is currently receiving medical care. that is the latest from the raf in the last few moments. that's all from the bbc news at six, so it's goodbye from me this is bbc news — our latest headlines. an raf red arrow hawkjet flying out from raf valley in anglesey has crashed. the raf have confirmed that one engineer has been killed. the pilot

survived and is currently receiving medical care. a committee of mps has written to the facebook founder, mark zuckerberg, calling on him to give evidence to them following the latest revelations about the harvesting of users' data. a plane carrying russian diplomats has taken off from stanstead for moscow — after being ordered to leave the uk by the prime minister, following the poisoning in salisbury. a two—year—old has died after being pulled from a car found in a river in cardigan. kiara moore was taken to hospital in cardiff but later died. in a moment it will be time for sportsday but first a look at what else is coming up this evening on bbc news... at seven o'clock, beyond 100 days will assess what impact the cambridge analytica allegations will have on facebook.
