a major crackdown on migrants crossing the channel in small boats. the uk government is planning to ban them for life — from returning to the uk. we have a special report from the seychelles — the country with the biggest heroin problem in the world. after a century, perfectly preserved at the bottom of the antarctic ocean — lloyds of london locate the insurance policy for shackleton�*s ship the endurance. and — it's already won four baftas and been nominated for nine oscars. the team behind the irish comedy "the banshees of inishiren" have been speaking to the bbc. to feel it and then said go out onto the world and received by all sorts of, you know, the corners of the globe, pretty surprising and cool.

a very warm welcome to the programme. are you a twitter user? if programme. are you a twitter user? , ., . , programme. are you a twitter user? , ., ., , , current and former staff at twitter have told the bbc�*s panorama programme that the company is no longer able to protect users from online abuse, following mass sackings and changes under owner elon musk. exclusive academic research, and testimony from twitter users, supports their claims, suggesting abuse is thriving under mr musk�*s leadership. our social media and disinformation correspondent marianna spring reports. with more than 350 million users, twitter�*s often described as the town square of the internet. but since elon musk took over last october, the company's been in chaos. the personal abuse i receive on twitter has tripled. so i headed to san francisco to look for answers. twitter used to have

around 7,500 employees. now, at least half of them have been fired or chosen to leave, including lisa jennings young. she worked on features designed to protect users like me from online hate. thanks so much for having us. it was not at all perfect, but we were trying and we were making things better. one of these protective measures was a nudge function, to scan tweets and ask users if they wanted to reconsider posting something potentially abusive. twitter�*s own research, seen by the bbc, appears to show the nudge and other safety tools being effective. so overall, 60% of users deleted or edited their reply when given a chance via the nudge. is it still happening? is there anyone working on it? no. there's no—one there to work on that at this time. the nudge does still exist. but when lisa and i tried it out, it appeared to be working less consistently. no nudge. 0ne engineer still working at twitter agreed to speak anonymously about what's been unfolding on the inside. it's like a building where all the pieces

are on fire. when you look at it from the outside, the facade looks fine, but i can see that nothing is working. like others i spoke to, he said it's been difficult to maintain features intended to protect twitter users from trolling and harassment. people like ellie wilson. while at university in glasgow, she was raped. she started sharing her experience as a survivor on social media last summer. but when she tweeted about her attacker injanuary — after the takeover — she received dozens of abusive replies. the trolls' accounts targeting her had become more active since the takeover. some were newly created, or appeared to have been reinstated after musk�*s amnesty on previously banned accounts. what would you say to elon musk if you had the opportunity?

i would ask — why are these accounts that are bullying and harassing people still allowed on the platform? i would like him to read some of the messages that i've been sent and tell me why those accounts are still allowed to be on twitter. musk has used votes on twitter to make decisions about its future. these polls have no statistical value, but having contacted him every way possible, i used one to try to catch his attention. over 40,000 twitter users voted and 89% of them said they'd like elon musk to do an interview with me. neither twitter nor musk have responded to the points raised in this investigation. twitter says defending and respecting the users' voice remains one of its core values. but the users i've spoken to are left with questions. marianna spring, bbc news. the prime minister of greece, kyriakos mitsotakis, has asked for forgiveness from the families of 57 people who died in a rail crash on tuesday. he said it should not have been possible for two trains heading in different directions to run on the same line without anyone noticing.

thousands of protesters, including striking rail workers, have again clashed with police. they blame the collision on government neglect. sofia bettiza reports. there's an outcry in greece. for the third day in a row, people have been protesting all over the country. this is a sign that anger is pulsing across greece and the systemic failings of that allowed this disaster to happen. on 28 february, a passenger train and freight train that were travelling in opposite directions ended up on the same track. 57 people were killed, mainly students. on sunday, hundreds of balloons were released in the sky above syntagma square in athens

to honour their memory. later that day a stationmaster appeared in court. he was charged with manslaughter by negligence. his lawyer said he's admitted to having a share of responsibility in the accident. and the prime minister, kyriakos mitsotakis, apologised to the bereaved families on facebook. ..he wrote. he promised a fast investigation. but many feel that's too little, too late. the crash has brought into sharp focus years translation: despite | the continuous warnings of the railway workers, those responsible were indifferent to our requests over the safety systems and that is what led to this traffic accident. translation: the government needs to change the way - they think.

they need to start caring about our lives. this must never happen again. we shouldn't be afraid to take our children in the metro and in trains. this is rapidly becoming a defining issue in the next greek general election, which could be just weeks away. sofia bettiza, bbc news. here in the uk... the government's planning a major new crackdown of migrants who cross the channel in small boats — by banning them for life from returning to the uk. the measure will be part of a bill to be introduced on tuesday — and there will be only some narrow exemptions. refugees groups say the scheme's unworkable and will leave thousands of people in limbo. our political correspondent helen catt has the story. small boats like these brought more than 16,000 migrants into the uk last year. an unfair and immoral trade, according to the prime minister, which he has personally promised to stop. it

but with some sunshine. frequent snow showers in northern scotland. temperatures dropping — barely above freezing by the end of the day. but through wales, the midlands, southern england, it's as you were — temperatures similar to the weekend, plenty of cloud, just one or two sunny breaks. here into the evening, though, we'll see some outbreaks of rain just as our weather front drifts its way south. there could be some sleet and snow for a time, notjust on the hills. in its wake, icy conditions for tuesday morning as temperatures drop quite widely. widespread frost away from the south and frequent snow showers the north coast of northern ireland, far north of scotland and down through some eastern counties of england. odd one elsewhere can't be ruled out but a cold day for all. this is what it will feel like — sub—zero for many through the bulk of the day. and what will follow will be a particularly chilly night. temperatures into minus double digits as we go into wednesday morning where the snow is lying across parts of northern scotland. from there on, though, it gets a bit complicated because we've got atlantic air trying to work its way back, fighting against that arctic air. 0n the northern edge of that, we could see some snow and that's dependent

on wriggles of weather fronts and pushing in areas of low pressure. certainly for wednesday, there is a chance we could see some snow across southernmost counties of england if that weather front gets close by, easing through the day before returning into the night towards the south—west. many, though, further north will see some dry and sunny weather continue. it will still be cold. but then, through the end of the week, it's just how quickly that boundary pushes northwards. there is a potential, particularly through friday into the weekend, of some more disruptive snowfall before things turn milder and wetter across the south. take care.
