welcome to bbc news. more than 200 mps have written to theresa may calling for assurances given to the windrush generation about their citizenship rights to be written into law. the letter, co—ordinated by the labour mp david lammy, said concerns over compensation, housing and legal rights had not been settled. the home secretary, amber rudd, will give a statement to the commons tomorrow afternoon. peter saull is our political correspondent tell us more about this letter. well i think it keeps the pressure on the home secretary, she will give a statement to the commons tomorrow, the letter asked a series of questions, specifically about the compensation scheme, how much the

windrush migrants might be entitled to, how it would work, how they would get the papers to prove addition citizenship and it calls for all of us to be backed up by legislation. lots of questions for amber rudd to answer when she returns to the commons tomorrow.l lot of calls for her to resign over targets and what she knew or did not know about targets within the home office, what is the latest on that, how much pressure do you think she is under? once again there is another call for her to resign from diane at that he has written a letter to the prime minister calling foran inquiry as letter to the prime minister calling for an inquiry as to whether amber rudd broke the ministerial code. downing street insists there is no need for an inquiry, says she did not mislead the commons, she was not aware of the target introduced to get rid of illegal immigrants from the uk. up is some concern, i think, this saga is doing some damage to the conservative party ahead of the local elections on thursday, a

couple of interventions in the sunday papers today from the community secretary sergei javad who himself is of immigrant stock and he said this could have been me, a member of my family, that's his initial reaction when he heard about the windrush scandal but he says to voters look at our record in pudding right. —— sajid javid. i think in general have of colleagues are rallying around amber rudd, she looks pretty said at the moment at least. the sole windrush saga has gone on and on for the government, they tried to do with it but it doesn't quite go away. no, it doesn't, there will be a lot of questions tomorrow in the commons for the home secretary, another intervention in the sunday papers and the observer newspaper, the labour mayor of london sadiq khan, writes about a0 calls the inhumane treatment of migrants across the country. i think you will hear more

of this in the coming days. peter, thank you. officials in seoul say the north korean leader has pledged to dismantle his country's nuclear test site next month, with foreign experts invited to ensure transparency. kimjong—un is also reported to have told the south korean president during their summit on friday that he would change the country's time zone to match the south. our correspondent laura bicker is following events in seoul. this is all coming from south korea, the presidential palace, some of these courts are coming from the meeting that kim jong boone had with president when on friday. what do we read into it, it seems injohn allan has the news reports saying his announcement last week to close the nuclear test site was met with some scepticism and it seems many people

have said it was badly damaged during a test last september. what he is saying is it's not badly damaged, when we dismantle it i will allow us and south korean experts in and crucially the media in. this has been a closed estate for some time, getting any access to north korea is very difficult, there are some news agencies allowed in some presence but they are closely monitored, i think he is saying, hang on, this is some sign that i am trying to make here, that i am serious but let's put a little note of caution in, this is one side he is allowing us to see, we don't know what other test facilities are out there. many experts speculate that there are various sites underground placed throughout north korea so although this is a step forward there are other steps to take. that was laura dekker reporting from seoul. members of the united nations security council have travelled

to bangladesh to visit refugee camps in cox's bazaar. the area is home to nearly 700,000 rohingya muslims fleeing violence in neighbouring myanmar. on monday, they will meet the country's leader, aung san suu kyi, before visiting rakhine state, the centre of what the un has described as ethnic cleansing. our myanmar correspondent nick beake has more from yangon. this is a significant moment, what we have here is leading members of the international community is siding that the situation in bangladesh, the rohingya crisis, poses a potential threat to the stability of this part of the world, it's not every day we see the likes of china and russia are great with western power is that they should join forces to go and see what is actually happening on the ground, there are two key aspects to this visit, members of the un delegation talking to some of the 700,000 rohingya people who fled from the

military crack down in my own mark. the second part of the visit will be tomorrow, they will talk to aung san suu kyi, the de facto leader, who has come under criticism for failing to speak up against the military. the un says there is no way at the moment that conditions in myanmar are ready for the sake than dignified return of the hinge of refugees, if of course they want to come back because when we listened to the stories of murder, sexual assault and other persecution they speak about, many people are far too frightened to go back. the un drawing attention to a50,000 rohingya still in rakine state, trapped without citizenship, access to education, health care, that's a good thing. as the bus repatriations deal, the big problem is the un and international community is not involved, it is a deal between myanmar and bangladesh and so far we have seen no movement, people have

not been willing or put in a position where they could come back if they wanted. the competition watchdog is being urged to begin an immediate investigation into plans for a merger of two of the uk's biggest supermarkets. the lib dem leader and former business secretary vince cable has warned that a deal between asda and sainsbury‘s threatened to create another monopoly in a market already dominated by a few big players. simon clemison has more. two may become one, but it's whether the big four becomes the big three which is now the key question. for years, having at least four separate supermarket giants has been seen as important, meaning customers can shop around. so what if sainsbury‘s and asda come together, still as separate brands but one company? as well as tesco and morrison, there are now other players — the discounters aldi and lidl. amazon also has a growing presence.

i spoke to the cma a few years ago, they said talk to us, we are not wedded to the idea of a before, tesco had a market share of 33%, now it's 20% you could see if we had asda and sainsbury‘s together they would have a lower share than tesco one sad. but labour says shoppers would sufferfrom rising prices and some staff could be out of a job. the lib dems say an investigation should start immediately. its competition which has led to pressure on the main players and while that and the need to act has been known for a while, news of the talks between sainsbury‘s and asda has onlyjust surfaced, and yet what would be a huge deal could be put forward as early as tomorrow. simon clemison, bbc news. it's been claimed thousands

of russian twitter accounts could have been used to rally support for labour, before last year's general election. an investigation by the sunday times and swansea university identified six—and—a—half thousand russian accounts which tweeted supportive messages for labour. the culture secretary, matt hancock, has described it as "extremely concerning". australia is promising to spend 290 million pounds to help restore and protect the great barrier reef. the world's largest reef system has been damaged by warming sea temperatures, which has bleached large swathes of coral in recent years, as well as pollution and run—off of pesticides and fertilisers from farms. phil mercer reports from sydney. the australian government says the multi—million dollar pledges the single largest investment ever in the great area reefs. there'll be new measures to reduce the flow of fertiliser from farms into the reef and a water will be waged on coral

eating starfish. ministers said there will be a bridge to mitigate there will be a bridge to mitigate the effects of climate change. we've had significant bleaching events in 2016 and 17 as reefs around the world and the great barrier reef is no different with heat stress. we've seen no different with heat stress. we've seen cyclone deadbeats and the insidious impact of the crown of thorns starfish. the bulk of the money will go towards improving water quality, this is what the world heritage committee told us was a priority. critics accuse them of being hopelessly unable to tackle the climate emergency facing australia's greatest natural treasure. the government has previously set an ambitious target to cut the nation's emissions by 2030. it's eight weeks since a nerve agent attack left a former russian spy and his daughter in a critical condition in hospital in salisbury. yulia skripal has been released but her father sergei is still receiving treatment.

the events of the ath of march have had a lasting impact not only on them, but on salisbury, with businesses and tourist attractions across the city continuing to report a fall in takings of as much as 70 percent. simon jones has more. most of salisbury may be open for business, but the police cordons remain. a reminder of what happened here eight weeks ago. at this shop overlooking the spot where sergei skripal and his daughter yulia were found poisoned on a park bench, they say some weeks' takings have been down by 70%. to suddenly go from a busy walkway, having a very busy shop to having almost no one coming, i can go three hours with no one walking past, it's a shock and i think everybody has found that difficult. we've actually come together and supported each other. here at salisbury cathedral visitor numbers have fallen by up to 30% this month,

compared with the same period last year. some of that is being put down to the weather, they are hopeful that reassurances by government officials that salisbury is safe for visitors will finally start to get through. the start of a pub crawl. if you want to go on an historic tour, see ed. put your hand up, ed... the latest event to try to persuade people back to the city, but some want reassurance. it's a scary world at the moment. i think anywhere you go, you didn't expect it in salisbury, definitely not. hopefully it will pick up. i'm a little bit concerned about the children. my son walks through the town centre every day, but not unduly. no concerns whatsoever. the decontamination process is beginning slowly. yulia skripal has been released from hospital but her father remains there. at this shop they hope some good can

come from the traumatic events. i believe we could look back in years to come, and whilst this has been a difficult time in salisbury‘s history, we could see this as a turning point. financial support is being made available for badly affected businesses, but many fear a return to normality could be a long way off. it's just it'sjust approaching it's just approaching 9:15am. the headlines on bbc news: more than 200 mps sign letter to the prime minister calling south korea says kimjong—un has promised to close north korea's nuclear test site next month — and has invited the world to watch. there are calls for an investigation

by the competition and markets authority into a potential merger between british supermarket chains sainsbury‘s and asda more on that story that more than 200 mp5 more on that story that more than 200 mps have signed a letter calling for guarantees to those affected by the windrush scandal should be written into law. on the line is the lib dem mp layla moran who's signed the letter our concern is that the government seems to be making things up as it goes along, the home office as a goliath of a department, all of us face in our post—backs, issues with migrants who don't have the right paperwork and you can't suddenly say that all go away, we want assurances and rethink the way to do it, let's

see if the home secretary comes on monday with that and that is the sort of assurance parliament needs. when you say you want legislation, what does that mean, and act of parliament? not at all, that should bea parliament? not at all, that should be a way of bringing this forward using a type of secondary legislation, that can be debated in the house, probably it would need to be in this case, we don'tjust need fa ke be in this case, we don'tjust need fake promises, we need a hotline and the decisions made on a case—by—case asus is entirely unclear. dissident ira on clear how the windrush generation, the children will get the justice they rather than have trust in the home office when i think is completely nonexistent, we need her to come before parliament and make sure this is being dealt with in a thoughtful and logical way stop —— it is paid the unclear. with in a thoughtful and logical way

stop -- it is paid the unclear. said judith javad says his parents emigrated from pakistan, he said it could have been his own family potentially being deported but he said he believes the government is committed to putting things right. -- sajid committed to putting things right. —— sajid javed. committed to putting things right. -- sajid javed. if that was the case we wouldn't see case after case after case of people falling through cracks. i don't doubt the government is saying we have this in hand, we wa nt is saying we have this in hand, we want proof and i think that is entirely reasonable to ask parliament. do you think this episode if you want to call about or scandal are some people have called it is this a problem that goes back to when theresa may was in the home office? theresa may, possibly even a fork, but hostile environment was created towards the end of the labour government but certainly accelerated under theresa may, we

remember the go home banshee instituted and i am told, i am a new mp elected last summer, i am told by my colleagues who have been around much longer that the home office has got more to call and in approaching immigration cases, i have seen that in the ones coming through in my constituency, they are taking you at your word even if you are getting involved as an mp, the computer says no seems to be the way it functions and that is not i think what the vast majority of people believe democracy should do, there are roads but you need to apply common sense and what we are seeing in the windrush generation and i think it isa windrush generation and i think it is a scandal, is the lack of common sense, the fact the individual is lost in this and if you don't have a small select number of documents that they can take off on a list you are considered to be part of this country and that is a scandal. —— you or not. many people will say you

are making political capital out of this and this is why you are writing a letter to the prime minister, you are using this scandal to score points against the government. are using this scandal to score points against the governmentlj don't points against the government.” don't agree with that, the letter is simply asking for assurances to parliament that this is being dealt with properly after a week of amber rudd keeps coming back and apologising because she keeps getting it wrong. what i do think we should do is wait, i am not calling for amber rudd to resign, i think her position is precarious but what we wa nt her position is precarious but what we want is for this to be sorted and what's clear is it is not being sorted. i am interested to see what will happen on monday, i expect think she will come to the house again but rather than apologise, what we are looking for is clear action, how is she going to sort this, is this the end of it, we don't want this happening more than anyone else. thank you. a bbc radio 5 live investigation

has uncovered a boom in fake online reviews — despite official warnings three years ago that they needed to be curbed. the competitions and markets authority has estimated that around 23 billions pounds spent every year is influenced by feedback on review sites. adrian goldberg from 5 live investigates is in our salford studio and can tell us more. explain a bit more about these fake reviews, because nowadays almost everybody goes by reviews from and for restaurants, holidays except. this is big business, £23 billion worth of influence, £23 billion worth of influence, £23 billion worth of influence, £23 billion worth of goods that are bought following the reading of online reviews. as you say, three years ago the competition and markets authority said there needed to be a crackdown, we decided to look at how

successful the crackdown and the abuse of online in reviews has been and we found for example we could buy for a dollar 99 cents, a positive review on ebay. is a review that we wrote which was then posted on the trust pilot website. we discovered for example bad amazon which in 2016 cracked down on free products in return for positive reviews, you can go on too close to facebook groups and if you go onto one of these you will be contacted by people who say to you, if you write us a positive review we will refu nd write us a positive review we will refund what you paid for the product in the first place. although amazon we re in the first place. although amazon were trying to crack down on free reviews, that's effectively what is still going on fire is closed facebook groups. we've even been told in developing countries there or review farms for people will write you bulk positive reviews for

relatively small amounts of money. clearly it's a booming business. adrian, thank you. and the full report will be on radio 5 live investigates at 11 o'clock this morning. a small solar power plant is in the process of opening at chernobyl — about 100 metres from the sarcophagus that covers the old nuclear plant. at the moment it's enough to power a small village but the ukrainian authorities are hoping it's the start of something bigger — making use of land that can't be farmed and is effectively abandoned by people and the fact that chernobyl is well connected to the national grid... but there are doubts about whether it's safe for people to work long term, as jonah fisher reports. why are you putting a solar powered station on probably the world's most famous radioactive site? in the

soviet union, the aftermath of the two double disaster was given prominence on the news bulletins to night. let me give you a sense of horror we are. that metal structure is a hundred metres away, covering chernobyl‘s reactor four that exploded catastrophically in 1986. does it worry you being so close to the nuclear reactor? not really. first of all we are fans of solar and we want to bring back this territory to the people, currently it has been uninhabited for the last

32—year is and this land cannot be used for anything else and we should be thinking about the development of solar plants. we are inside the arch of the new safe confinement, the area we are in this relatively safe, we were at these respirators simply to keep out contaminated dust particles and what you see in front of you is the shelter that was built over the damaged reactor. gaming is big business. the billion pound industry is creating a new wave of celebrities and it's even been tipped as a new olympic sport. now, a 13—year—old from kent has become one of the world's youngest professional gamers. kyle jackson has become so good at the game fortnite that he could start earning serious money. joe lynam went to meet him. for many of us, fortnight is the length of time you spend on your holidays overseas every summer. but for millions of young people, it's the hottest video game on the planet right now.

and for this 13—year—old, it's potentially a lucrative future career. kyle jackson is so good at fortnite that he has been signed to play with a team of professional gamers. so how did he start? played video games all my life basically. i started playing competitively when i was around nine or ten. i got into, like, halo, call of duty, games like that, and ijust — i realised that i could probably, like, go to a pro level if i kept playing at the level i am at that age. gaming is no joke. it's big business. thousands of people pay to watch the experts at play around the world. there are even celebrities. it's becoming a multibillion—dollar industry, just games, production of games, publishing of games, and the e—sport scene, so it's notjust one thing now, it's a whole industry that's, you know, wrapped up in a bow. in the game, you need materials to build. kyle says he is doing well

at school, and that allows him to do what many boys dream of — play games and make money. joe lynam, bbc news. for the second year running president trump did not attend the white house correspondents' dinner last night. it is the second year that mr trump — who has a turbulent relationship with the mainstream media — has declined to appear, instead spending time with supporters in michigan. andrew plant has more. a glamorous a—list extravaganza. a fixture of the washington calendar. but this year's white house correspondents' dinner had one notable absentee — the president, who left in helicopter marine one earlier in the day, snubbing the event for the second year running, holding a rally in michigan instead. you know, you may have heard i was invited to another event tonight, the white house correspondents' dinner. booing.

but i'd much rather be in washington, michigan than in washington, dc right now, that i can tell you. mr trump was stung here seven years ago — before his presidency — by barack obama, who mockingly called mr trump ‘the donald' and ridiculed his alleged belief in conspiracy theories. mr trump has said it is due to fake news stories that he chooses to forego the event, often arguing he receives unfair media coverage. the correspondents' association dinner now attracts the biggest names in american entertainment, but after around 100 years of evenings with the president, the biggest name in american politics has clearly decided he won't be continuing the tradition. andrew plant, bbc news. time for a look at the weather with matt taylor hello, strong winds and heavy rain
