this is bbc news. the headlines at 11:00pm: the prime minister apologises again, this time to mps, for the government's treatment of caribbean migrants. she offers reassurance to the windrush generation, but she still faces criticism of her time as home secretary. people in this generation, who came here from commonwealth countries, have built a life here. they have made a massive contribution to the country. these people are british. they are part of us. under her, the home office became heartless and hopeless, and doesn't she now run a government that is both callous and incompetent? the substance used to poison a former russian agent was a highly and blamed mrs may.

but the prime minister said that a decision to destroy landing cards showing when people first came

to britain was made by officials under the last labour government. our political editor laura kuenssberg has the latest. that was a long time ago. yeah, it was. that veranda — i used to slide down there. jamaica — country of his birth. britain — country of his home. nick broderick came to london as a toddler with his mother and sister in the late 1950s. but decades later, he says he was threatened with deportation, and even lost hisjob. one minute, i'm going back to a country, when i was a little boy, i know nothing about. you know, as far as i know, this is my home. all because, under tightened immigration rules, he couldn't prove he had the legal right to live here. i don't think people have realised the mental pressure it puts you under, to have this on you. you feel like a criminal. it's awful, it really is awful.

i've always worked and looked after my family. that's what a man does. but not like this, you know. especially when you think there's no one there, and i couldn't afford a lawyer. reporter: are you to blame for the windrush fiasco, prime minister? she was in charge at the home office for years when the laws became stricter and stricter. but the prime minister has apologised again, because the windrush generation should never have been caught up in the changes. these people are british, they are part of us. and i want to be absolutely clear. i want to be absolutely clear that we have no intention of asking anyone to leave who has the right to remain here. but what happened to records that could have avoided at least part of the problem? in 2010, the home office destroyed landing cards for a generation of commonwealth citizens, and so have told people,

we can't find you in our system. did the prime minister, the then—home secretary, sign off that decision? speaker: prime minister. no, the decision to destroy the landing cards was taken in 2009 under a labour government. the decision was taken by officials, not ministers, but the anxiety of those affected goes way beyond paperwork. the windrush generation came to our country after the war, to rebuild our nation, that had been so devastated by war. under her, the home office became heartless and hopeless. reporter: was it theresa may? good morning. while this home secretary has to deal with an accidental mess, the overall crackdown under the former home secretary was entirely deliberate.

listen to this. we want to ensure that only legal migrants have access to the labour market, free health services, housing, bank accounts and driving licences. and this is notjust about making the uk a more hostile place for illegal migrants. it is also about fairness. the intense push by the government had eyebrow—raising tactics, but ministers believed the home office had hefty public support. if you haven't got all of the right paperwork, you're basically a bad guy, and they have a culture of disbelief. and their absolute commitment, since 2010, has been to cut immigration and drive as many people as they can out of the country. and i think it is that cultural assumption which has driven a lot of the problems we've seen around the windrush generation. this mess wasn't deliberately made here at the home office, but it didn't come from nowhere. it is rather the by—product of decisions taken over a period of many years, to tighten the immigration rules, then to tighten them again, and then again and again to bring in more restrictions —

moves that ministers believed then had the public support. consequences that weren't intended, but weren't random either. anxiety for thousands of people, for whom britain was and is a place called home. laura kuenssberg, bbc news, westminster. the entertainer and television personality dale winton has died at the age of 62. he presented a range of programmes, including supermarket sweep and pets win prizes, in a career that started as a dj in london, before he joined the bbc in 1986. in a statement this evening, his agent said he died at home. joining me now from south london is tv critic from the tv times emma bullimore. thank you forjoining us. he has

been described as tv‘s mr nice guy. what was his appeal, do you think? he wasjust what was his appeal, do you think? he was just unashamedly himself. you know, he was a little bit cheesy. he was always smiley and up heat and in a world where our presenters on tv can bea a world where our presenters on tv can be a little bit sort of bland or identikit, he shone out and he was a conch at professional as well. whenever you watch one of his programmes you knew he was going to present them perfectly, and hejust exceeded personality. and so many people have so many fond memories, even of shows like supermarket sweep, that yes, they were a little bit cheesy, but they were so much fun and his personality was a big pa rt fun and his personality was a big part of that. yes, i mean, he basically came across as someone who didn't take himself too seriously, but of course, he was a consummate professional. so he made looking relaxed and shield and as if he was having a laugh very easy, but it is a difficult thing to do. it is, looking natural and tv is a very difficult thing to do. and he loved show business, he loved being part

of it and you could tell. so he took it seriously and it wasn't a joke for him. he had this amazing warmth and you had these contestants on his game shows. you really felt like he got on with them, he connected with them, he made them feel at ease, and thatis them, he made them feel at ease, and that is how he made us feel as viewers as well. he made us feel relaxed so that when he was presenting something such as pets win prizes, where anything could happen, he made us feel like we were a long for the ride because we were so warm. a long for the ride because we were so warm. he was a joy to watch. as you alluded to, he challenged —— channelled his inner cheesiness, didn't he? he did, even when he had his leather jackets on, didn't he? he did, even when he had his leatherjackets on, always a little bit cheesy. that is what we liked about him. he was himself. and you can't present a show like supermarket sweep and be really serious about it. he knew that, and he was a professional, and he did a fantastic job. he is going to be missed by many. dale winton, who has died at the age of 62 the head of the 0pcw,

the global chemical watchdog, has rejected russian claims that traces of another nerve agent were discovered in salisbury, where the former russian agent sergei skripal and his daughter were poisoned. the british representative to the 0pcw said that a highly—purified version of novichok had been confirmed as the nerve agent used which could only be made in a sophisticated facility. 0ur moscow correspondent steve rosenberg has been to speak to a retired russian scientist who worked on the novichok programme. six weeks after the salisbury poisoning, britain and russia are locked in a war of words about the nerve agent that was used and about who attacked sergei and yulia skripal. at the un, britain's ambassador was in no doubt who was to blame. in our view, mr president, only russia had the technical means, operational experience, and the motive to target

the skripals. but at the 0pcw, the global chemical weapons watchdog, russia's representative said his country had never had any novichok programme. 0n the russian riviera, though, i meet a scientist who worked for the soviet union's nerve agent programme. vladimir says he created the novichok that was later used against the skripals. it has been identified in russia by the code a234. how certain are you that the substance which you synthesised is the one that poisoned the skripals. translation: i have no doubt that it was a234 that poisoned them. judging by how pure the test sample is, this may well be a batch that i made with my own hands. it has a long shelf—life, virtually no expiry date. the nerve agents were developed and tested at this site in southern

russia. one day, vladimir uglev was involved in an accident there. translation: my right hand got covered in nerve agent. i put it in hydrochloric acid straightaway, then washed it with a special alkali solution, with hydrogen peroxide. you could say the skripals and i were baptised with the same novichok. as for the poisoning in salisbury, the scientist is convinced his country was behind the attack. translation: you'll never prove it, unless you find the actual test tube that contained the poison. but the logic of events suggests that this was russia, and so do the action of our leaders. they were quick to shout, "we didn't do it," just like a thief who points the finger at somebody else. the russian state insists it is innocent, but the world isn't convinced.

following the nerve agent attack, trust between russia and the west has faded. the new dawn is confrontation. steve rosenberg, bbc news, southern russia. president trump has confirmed that the director of the cia, mike pompeo, travelled to north korea last week to hold secret talks with the country's leader, kim jong—un. the meeting, the highest—level contact between the united states and north korea since 2000, took place after mr pompeo was nominated as us secretary of state, but he has still not been formally confirmed in that post. president trump says he plans to hold a face—to—face meeting kimjong—un in the coming months. the rate of inflation in the uk slowed last month, meaning an expected rise in interest rates could be delayed. experts say it is further evidence that the long squeeze on pay might be coming to an end. inflation as measured by the consumer prices index dropped from 2.7% in february, after recent rises, to 2.5% last month. that is the lowest rate in a year. wages have also risen, increasing at a rate similar to prices, by 2.8%. if the trend continues, it would confirm the pattern

of rising wages and lower inflation. a man who deliberately infected five sexual partners with hiv has been given a life sentence at lewes crown court, in the first case of its kind in the uk. daryll rowe tried to transmit the virus to as many men in brighton and northumberland as possible. he will serve a minimum of 12 years in prison. plastic straws, drinks stirrers and cotton buds could be banned from sale in england under plans being put forward by the government. a consultation on banning the disposable plastic products will launch later this year in an effort to cut the amount of waste which ends up in rivers and oceans. the prime minister will call on other commonwealth countries to adopt similar policies at a heads of government meeting tomorrow. that is a summary of the news. newsday is coming up at midnight.

now on bbc news, it is time for newsnight with evan davis. clayton barnes — shut out of britain and cut off from his family. this is where we got married, had kids, where he worked. so it is — i don't want him to die without that memory. and i want to be there if he does pass. i will not be there to say goodbye really. it would be a phone call. i did want to say goodbye to my dad on the phone. the home office really did take the instruction to create a hostile environment seriously — far too seriously. can we trust them with anything, let alone brexit? and can politicians get away with blaming poor administration? or do they have to take responsibility for setting the culture? the former head of the civil service and a supporter of rigorous immigration control will argue that out.

meanwhile, commonwealth leaders gather in london and meet the queen. is it still relevant to us these days, let alone to the other 52 member states? and how does it feel to have your business ruined by your bank? i cannot explain the pressure in your chest when something like that happens. you feel you cannot breathe properly. you shake. you do not sleep. it is not until you go through it, you cannot explain it. hello. home office scandals tend to have a weird and extended life—cycle.
