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. firstly, what is in this letter that has been signed by 200 mps? more than 200 largely from opposition parties, the labour party, the snp, the liberal democrats and one tory

mp and it accuses the conservatives of making up policy on the hoof, measures announced by amber rudd to be backed by legislation, it once the compensation scheme, more details to 5; given was individuals can get hold of heeee ieeieieuelé eee eee re'e ei the eeeee ieeieieee'e eee eee ee'e ee the they need to eeeee ieeieieee'e eee eee ee'e ee the - they need to prove their the papers they need to prove their citizenship. amber rudd is under a lot of pressure over claims she misled parliament by saying she wasn't aware of immigration targets at the home office for a deporting illegal immigrants. the former immigration minister now currently conservative party chairman brandon lewis has been on the andrew marr programme a short time ago on bbc one and he was sent that memo, it was addressed to him, amber rudd was copied into it and he said i remember that the mob but it dealt with regional internal immigration targets from previous years and an

aspiration to increase deportation by 10% the following year. listen to what he had to say. —— that the memo. the memo did not talk about the internal targets that was referred to in the home affairs select committee, i had the memo and what it outlined was the overall figure will figure of the achievement they'd had in the previous year. i was working on a wee kly previous year. i was working on a weekly basis to ensure we were doing everything we could working with police and local government to make sure we we re police and local government to make sure we were doing public could to vulnerable people, crackdown on criminal is and remove people here illegally and yes i did talk to the home secretary about that and the overall work we were doing and the ambition we had to see... she knew there were targets? she must have known there were targets. what home secretary was very aware of was the ambition to see if the crease and the numberof ambition to see if the crease and the number of people who were here illegally, removing foreign national offenders, those internal targets

we re offenders, those internal targets were not in the memo and not figure she was aware of. that was brandon lewis earlier, amber rudd has been under huge political pressure, calls for her to resign, do you think she has weathered the storm, she said? for the moment she appears to have the support of cabinet colleagues, brandon lewis saying if she said she didn't see the memo i believe her, she is a very good home secretary in his view. but the labour party upping the calls for resignation, it will be interesting to see tomorrow how it goes down in the house of commons, she will return and give a statement, answering questions on the letter from 200 mps, answering this question about the memo which seems to be running on and on and on. peter, thank you. 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. it could mean there's enough choice. a shifting landscape which experts say is already recognised by the competition and markets authority. i spoke to the cma a couple of years ago and they said, talk to us, we are not absolutely wedded to the idea of a big four. we recognise the market changes, there are smaller players. a few years ago tesco had a market share of 33%. now it has a share of 28%. you can actually see if you suddenly had asda and

sainsbury‘s together, they would have a lower share than tesco once had. 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. let's speak to the liberal democrats leader and former business secretary sir vince cable. it's clear that this is a response to huge pressure in the industry particularly from amazon and online, do you understand the reasons for this merger? i can understand the commercial reasons but we have to ta ke commercial reasons but we have to take account of public interest, you are going to get a very substantial

concentration of power in the marketplace, in the mid market for this new market will be competing with tesco, they will have a double their position and more important at local level you will get lots of local level you will get lots of local monopolies being created but i was intrigued by the argument being put out that one of the arguments for this merger is that they will be able to get much better procurement, what that means, they will squeeze the farmers and suppliers even more soi the farmers and suppliers even more so i think there is a very strong public interest case here for getting the competition authorities, the cma to investigate it, probably to force them to make advertisement, that will be the logical way forward and frankly the cma has been weak in recent yea rs and frankly the cma has been weak in recent years and i think for the banking system, i am hoping under the new chairman they will be a little bit more severe. do you think this could cost jobs, little bit more severe. do you think this could costjobs, potentially it might be damaging or the customers but also people who work for asda

and sainsbury‘s? but also people who work for asda and sainsbury's? yes, it's potentially bad news for the employees, customers and suppliers. for all of the reasons they are hoping to get large amounts of frost out of it is by getting rid of staff, they don't put it like that but that's an inevitable consequence. the competition inquiry has to focus on the customers, that's their job has to focus on the customers, that's theirjob and i think potentially that is very serious. what will happen, when you get a big out—of—town stores that has got a com plete out—of—town stores that has got a complete local monopoly, there will be many more of those once the group emerges. since we have you here let me ask you about the continuing pressure on the home secretary. a lot of calls for her to resign, what is your view and also this letter from 200 mps asking for the windrush promises that have been made by the government to be put into law, is that actually necessary?” government to be put into law, is that actually necessary? i would support it, it is a terrible

episode. i don't think it was intended, it is an unintended consequence of this pressure that is what they are on vulnerable groups of this kind. as far as amber rudd is concerned and notjoining a lynch mob, i think we have to hear what she says tomorrow, she's either misled parliament, i know it's unlikely, it could have been the case or she simply did not know about something that was almost public knowledge, that the home office was operating some kind of quota office was operating some kind of q u ota syste m office was operating some kind of quota system for their staff to get rid of people. and we are talking about individuals, large numbers of people are not being given, if they are facing deportation, due process, they are just being got out of the country to make up a number, and is absolutely unacceptable. when you say this wasn't intended use a you absolve the government of blame? no, no, i certainly did not mean that, but what is happening across—the—board, it wasn't just

but what is happening across—the—board, it wasn'tjust in relation to the windrush family, you see this with visitors when there is no longer an appeal, random rejections, lot of hardship calls, rejections, lot of hardship calls, rejection of people marrying people from overseas, ruled out on the basis of some error in an application, i get hundreds and hundreds of cases in my constituency, all mps do, lost paperwork, massive delays, but of course at the end that the people who suffer are people like the windrush victims who are treated to inhumane treatment as a result of the very inefficient and oppressive system. good to talk to you. thank you for coming in. 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 quotes are coming from the meeting that kim jong—un had with president moon on friday. what do we read into it, it seems kim jong—un has read 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 state 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. the new american secretary of state — mike pompeo — who's on his first overseas tour of the middle—east — has arrived in saudi arabia. it is expected that iran's missile program will be a major topic in talks on sunday between pompeo and leaders from saudi arabia and israel. our correspondent tom bateman is following developments from jerusalem... how significant do you think this visit is? well, remember mike pompeo has only been sworn into office as secretary of state for eight few

days and he started with this hastily arranged trip to key allies of the us in the middle east, wanting he says to bring swagger back to the us state department, i think that gives you some sense of the line of his thinking at this crucial moment. just a couple of weeks before we get a decision from president trump and whether he will recertify or withdraw the us from the iran nuclear deal. remember over the iran nuclear deal. remember over the last week there have been european leaders in the white house urging mrtrump to european leaders in the white house urging mr trump to stick with the deal or at the very least try to re—negotiate and fix it as mr trump has one of those options, potentially open to him. what is to pompeo will hear from leaders potentially open to him. what is to pompeo will hearfrom leaders in saudi arabia, also in israel, is deep opposition to the nuclear deal. they believe as mr trump has said in the past, that the deal in boldon is iran, it enhances its strategic position in the middle east and

these countries deeply opposed to that. they have always said they don't think the nuclear deal goes for enough in that it gives sanctions relief to iran on the nuclear issue but they think it does nothing to halt the iranians ambition towards ballistic missiles. thank you. the headlines on bbc news: more than 200 mps sign letter to the prime minister calling for government promises to windrush migrants to be written into law. there are calls for an investigation by the competition and markets authority into a potential merger between british supermarket chains sainsbury's and asda south korea says kimjong—un has promised to close north korea's nuclear test site next month — and has invited the world to watch. sport now and for a full round up, from the bbc sport centre, here's richard. manchester city playing today.

arsene wenger travelling to old trafford to take on manchester united for the last time as arsenal manager. full commentary on bbc radio 5 live from 4:30pm, after so many battles against united, is an in reflective mood. i don't know the kind of reception i will get but i will be focused on winning the game. some great battles in 22 years. for me, it will be at stake to recover from that result and before we go to atletico madrid. if i get a good reception i'd take it. day nine of the world snooker championship, just

under way, let's cross live to the crucible. look at what's happening. judd trump playing the world number 27 ricky walden, in the first frame of the second—round match. trump looking for a more consistent performance after throwing away a big lead in the first round match against chris wakelin. watching the black going. there it goes. on the other table, another former finalist is generally playing anthony mcgill, that in its early stages. to a rising star in american football, shaquille griffin has become the first one handed player to be drafted by an nfl team after being selected by the seattle seahawks on the fifth round. he had his left—hand amputated when he was for having been born with a condition which prevented his fingers growing normally. hejoins his brother at the seahawks. i was seven years old

and my coach was telling me but all was for two handed players, my first interception... griffin, linebacker, university of florida. griffin! everett, knows about the ball, relentless, big hitter. this is an outstanding player. who is to say he cannot lay in the nfl? people call me shack. don't tell my brother, he doesn't like that. my brother plays for the seahawks, doesn't like that. my brother plays for the sea hawks, we doesn't like that. my brother plays for the seahawks, we are a typical twins. he helped me get my maths grade and he helped me get my english. i'd talked to all my friends and they kept saying why are you talking, why are you ignoring me? it was game over, that was the

last time i went to classes. basically, the circulation was cut off to my hand before it fully developed, i remember waking up and i grabbed developed, i remember waking up and igrabbed a developed, i remember waking up and i grabbed a knife to cut my own fingers off, my mum stopped me and the next day she took me to have an operation to have my fingers removed andi operation to have my fingers removed and i was out playing football the next day. after that surgery, i wouldn't change it for nothing in the world. obviously me and my brother had big dreams about playing together, drafted, iwant brother had big dreams about playing together, drafted, i want to be excited, it is a dream come true, i can't truly say i dream about this andi can't truly say i dream about this and i am loving it. —— i can truly say. what a fantastic character. that's all for now, more from the sports team throughout the afternoon. 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 details on the visit. this is a significant moment, what we have here is leading members of the international community deciding 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 agree with western powers 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 from the military crack down in myanmar. 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 safe and 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 450,000 rohingya still in rakine state, trapped without citizenship, access to education, health care, that sort of 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. 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 6,500 russian accounts which tweeted supportive messages for labour. the culture secretary, matt hancock, has described it as "extremely concerning". 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 spent every year is influenced by feedback on review sites. earlier i spoke to 5 live investigates presenter adrian goldberg, who told me more about theirfindings. this is big business. we're talking about £23 billion worth of influence, £23 billion worth of goods that are bought following

the reading of online reviews. as you said, three years ago the competition and markets authority said there needs to be a bit of a crackdown, so we decided to look atjust how successful the crackdown on the abuse of online reviews has been and we found, for example, that we could buy forjust $1.99 a positive review on ebay. so that's a review that we wrote which was then posted on the trust pilot website. we discovered, for example, that amazon, which in 2016 cracked down on free products in return for positive reviews, you could go on to closed facebook groups and if you go onto one of these closed facebook groups you'd be contacted by people who say to you, well, if you write us a positive review, we will refund what you paid for the product in the first place. so although amazon were trying to crack down on free reviews, that's effectively what is still going on via these closed facebook groups. we've even been told that

in developing countries there are review farms where people will write you bulk, positive reviews for relatively small amounts of money. so clearly, it's a booming business. and the full report will be on radio 5 live investigates at 11 o'clock this morning. 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 4th 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, its 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. australia is promising to spend £290 million 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 pledge is the single largest investment ever in the great barrier reef. there'll be new measures to reduce the flow of fertiliser from farms into the reef and a war will be waged on coral eating starfish. ministers said there will be efforts 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 cyclone debbie 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. 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. time for a look at the weather with matt taylor.
