and welcome to bbc news. the former immigration minister, brandon lewis, is supporting a claim by the home secretary that she didn't know about home office targets for removing illegal immigrants. amber rudd told a commons committee earlier this week that she wasn't aware of the targets, then on friday said she hadn't seen an email lastjune which gave details about the policy. she has resisted growing calls for her to resign. our political correspondent peter saull reports. another day, another government minister leaping to the defence of the embattled home secretary. amber rudd denies reading a memo about the

deportations of illegal immigrants. that memo was addressed to the then immigration minister. it was a memo to me. do you remember reading it? yes, i do actually. brandon lewis went on to say that he and amber rudd discussed an ambition rather than a target to increase the numbers. i was working through on a weekly basis to make sure that we were doing everything that we could, working with the police, working with local government, making sure that we were doing all we could to help vulnerable people, to crack down on criminals and to remove more people who were here illegally. yes, i did talk to the home secretary about that and the overall work that we were doing and the overall ambition to see an increase in numbers. last week, amber rudd told a commons committee that there were no targets at the home office. we do not have targets for removals. brandon lewis says she was being asked about regionalised internal targets that she wasn't aware of. the chair of that committee, yvette cooper, has tweeted that that is clearly not true. meanwhile, more than 200 mps have signed a letter calling for assurances given to the windrush generation to be written into law. we have had a lot of nice words

from the dispatch box but it means nothing if there aren't rights enshrined, in legislation and the best way to do that is with a quick statutory instrument in parliament. so people know what compensation they are getting, they know what the burden of proof is and they know that they won't be deported. the empire windrush... the windrush scandal has prodded some awkward questions for the conservative government. but a former liberal democrat minister thinks all the main parties share some responsibility. goes back to new labour, i think the working assumption that successive governments have made is that the public out there are pretty bigoted and they have got to be given red meat in the form of these very restrictive measures and it has done a lot of harm. i think the interesting thing about windrush, is that perhaps for the first time the public opinion has been ahead of the politicians in seeing that there is a terrible injustice. the home secretary has apologised several times in recent days, for the moment she appears safe in herjob. there will be more contrition when she

returns to address the commons tomorrow. the north korean leader kimjong—un is reported to be promising to dismantle his country's nuclear test site next month — with international experts invited to ensure "tra nsparency". kimjong unis said to have made the promise during friday's historic meeting with the south korean president, moonjae—in. from seoul, laura bicker, reports. as they celebrate their past, south koreans are trying to envisage a different future. their once threatening neighbour is now promising peace. but can kim jong—un be trusted? i used to think of north korea negatively. little by little i realise that we are one people and i am touched by it. our country is the only divided country in the world and it hurts me. i hope unification really happens.

this time, kimjong—un speaks with conviction i think this time it will be different. north korea has pledged to destroy its nuclear sites before. they even blew up a cooling tower in 2008, a gesture of goodwill. secretly, they continued to build weapons. this time, they want to close this... the last six nuclear tests were carried out out here. they are prepared to let experts and the media witness the closure. some fear they are putting on a show. they are masters of propaganda. now is the time to collect ourselves and concentrate on the key task, which is dismantling north korea's weapons. kim jong—un is also turning

back time, literally. in 2015, he changed their clocks and since then they have been half an hour behind seoul. now they will become one time zone. changing the clocks is a huge symbolic gesture of unity. he has also told south koreans that his weapons pose no threat to them or the united states. but the us does not want them to have those weapons in the first place. south koreans have to wait and see if the us president can do a deal on the neutralisation. history has told them to be wary of the north, but there is hope here that this could be the start of a new era. police have taken two wanted men back into custody after they were found tied up on a bench in a county armagh village.

james white and alexis guesto were wanted for offences including a breach of their licences. images shared on social media appear to show them tied up and covered in paint. our correspondent in belfast, john campbell is following the story. well, the police public protection branch had issued an appealfor information about these two men, they have released their pictures, they had also given details of a car which was seen in the south armagh area. south armagh is a particular closely knit rural community. last night, police were called there to the village of mullaghbawn and they found these two men tied to a bench, their hands bound with cable ties and paint poured over their heads in what was apparently a vigilante attack. a local councillor says that this incident was unfortunate but understandable given that tensions have been running high in the area. the police say it is completely unacceptable, the two men had to be treated in hospital and they are now investigating an assault. rohingya refugees in bangladesh have been appealing

to visiting un ambassadors to help them safely return home. a delegation from the un security council is visiting refugee camps in cox's bazar — home to nearly seven hundred thousand rohingyas who've fled violence in myanmar. their tour comes amid warnings that the coming monsoon season could worsen conditions in the camps. nick bea ke reports a break from the misery of life in the biggest refugee camp in the world. hundreds of rohingya people gathered to greet the un delegation. but as come to hear their harrowing stories. we are standing here to demand justice as the myanmar military have killed our men and tortured women. this is what she's talking about. burmese military torch rohingya villagers glastir and villagers last year and

forced muslims to flee for their lives. it is not known how many exactly were murdered before they could escape. now in camps across the border in bangladesh, the survivors have placards but not much else. the security council says it wants to help the authorities here prepare for the imminent monsoon season. and try to find a way for refugees to return safely to myanmar, if indeed, anyone too. tomorrow, the delegation will leave bangladesh and fly to myanmar. the leader has been widely criticised for not doing more to protect the rohingya. the burmese army has always claimed it did not target these people but was rooting out terrorists. many believe this is the face of a crime against you manage of a crime against humanity 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 have 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 great barrier reef is australia's greatest national treasure. but it is under siege. for two years running, it was hit by major coral bleaching, which scientists blame on warmer sea temperatures. then there was an assault by coral—eating crown of thorn starfish. these ferocious predators will be targeted by the new multi—million dollar plan to revive and restore the reef. farmers near the queensland coast will be encouraged to change their ways, to reduce the flow of fertilisers and pesticides into the sea. it is part of a pledge that the australian government says is the single largest investment ever in the great barrier reef.

we will also be providing money for scientific research to build more resilient coral to deal with heat stress and light stress. this is $100 million for these activities. we will be putting money towards better data management, so that we understand better what is happening in the reef, so that we can deal with the challenges. we will be spending money, in terms of working with local indigenous communities, the traditional owners who have such a big role to play. ministers say there will be efforts to mitigate the effects of climate change, but they gave no specific details. critics accuse them of being hopelessly unable of tackling the climate emergency facing this underwater paradise that snakes down north eastern australia. the government in canberra has previously said an ambitious target to cut the nation's emissions by 2030, but this is a country heavily dependent on cheap supplies of coal for its power. conservationists argue

that until this reliance on fossilfuels is broken, there can be no real hope of preserving the great barrier reef. an 18 year old man has been arrested after four people were taken to hospital — two with potentially ‘life changing' injuries — following a collision in newport. a police cordon has been set up in the city centre — after the incident at about five thirty this morning. a car was found burned out in a nearby street, a short time afterwards. the former speaker of the house of commons — lord martin of springburn — has died. his son confirmed the 72 year old passed away this morning after a short illness. he was speaker from 2000 until he was forced to step down following his handling of the mps expenses scandal in 2009— the first speaker to do so in 300 years. the eu's chief brexit negotiator, michel barnier,

has said the time has come for the uk to "resolve the contradictions" in its irish border policy. mr barnier was writing in ireland's sunday independent newspaper, ahead of a visit to the country tomorrow. he said there needed to be "substantial progress" on the issue by the next meeting of eu leaders, injune celtic have won the scottish premiership for the seventh year in a row. they thumped their traditional rivals rangers 5—0 at parkhead. if they beat motherwell in the scottish cup final next month, they'll complete the treble for the second season in a row. let's speak to our reporter chris mclaughlin at parkhead. afternoon. an emphatic win for celtic, how did they do with? absolutely. it was indeed an emphatic win. they were determined to put on a show here this

afternoon. that is exactly what they did. five goals. in all honesty, it could've been a lot more than that. they have been dominant, of course, since he arrived here in glasgow. also, remember this is the fixture that the authorities here in glasgow and in scottish football wanted to avoid. there were some fairly nasty scenes in 1999 here, when rangers clinched the title. everything peaceful here, so far, today. but celtic increasingly dominant. they have that one game left ago, the scottish final. if they win that they complete a historic double trouble. it is all down to brendan rodgers, many of the celtic fans believe they will party into the night. for rangers, it is more disappointment for them. the club

believe they are on the brink of securing steven gerard as their new manager. a penny for his thoughts if he was watching today. we will find out, hopefully, in the next few days whether he has agreed to take on that new role. but it is all about celtic, today, here in glasgow. any sign ofany celtic, today, here in glasgow. any sign of any team who can challenge this dominance? no. absolutely not. at the moment, the gap between celtic and rangers is pretty much as big as it has ever been. it is all about finance and football these days. celtic‘s finances dwarf their rivals. rangers have been trying desperately to claw back some ground on celtic. there is a feeling that

here in scotland that as long as brendan rodgers remains in charge, rangers are going to struggle. the headlines on bbc news: labour's david lammy leads 200 mps who've signed a letter calling for government promises to windrush migrants to be written into law. south korea says kimjong—un has promised to close north korea's nuclear test site next month — and has invited the world to watch. in northern ireland, police have taken two wanted men back into custody after they were found tied up on a bench in a county armagh village. and in sport, as we just heard, celtic have won a seventh consecutive scottish premier ship title. brendan roger's side are aiming for back—to—back troubles. a

lewis hamilton has won the azerbaijan grand prix. the mercedes driver overtook sebastien battle and ba ftas got a driver overtook sebastien battle and baftas got a flat tire. i will have details on those and a lot more for 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 billion spent every year is influenced by feedback on review sites. the 5 live investigates presenter, adrian goldberg, gave more details about theirfindings. this is big business. we are talking about £23 billion of influence, £23 billion worth of goods that are bought following the reading of online review stores. as you say, it was said

that there needed to be a crackdown. we decided to look atjust how is excess full of crackdown has been. we found, for example, that we could buy forjust $1 99 a positive review on ebay. that is a review that we wrote, which was then posted on the trustpilot website. we discovered that amazon, which in 2016 cracked down on free products return for positive reviews, you can go onto closed facebook groups and if you go onto one of these groups you will be contacted by people who say to you, if you write us a positive review, we will refund what you paid for the product in the first place. although amazon are trying to crack on free reviews, that is effectively what is still going on. we have 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. clearly, it is a booming business. and you can get more on that story via the 5live website. the prime minister theresa may has held talks on the telephone with both french president emmanuel macron and the german chancellor angela merkel. they discussed the importance of the iran nuclear deal as the best way of neutralising the threat of a nuclear—armed iran agreeing that the priority of the international community remained preventing iran from developing a nuclear weapon. the european leaders' talks came as new us secretary of state, mike pompeo also reiterated america's determination to prevent the iranians ever getting a nuclear weapon. on his first visit to the middle east, mr pompeo said than iran has shown worsening behaviour since the 2015 nuclear deal, and he blamed tehran for supplying weapons to houthi rebels in yemen.

iran has only behaved worse since the deal was approved. in yemen, iran continues to support the houthi rebels. this is in violation of the un security council resolutions. the houthi continued to fire missiles into saudi arabia, threatening the saudi people. while we will continue to assist saudi arabia and support its right to defend its own borders, a political solution is the only way to advance long—term stability in yemen. to talk more about mike pompeo's visit, let's speak to our middle east analyst alan johnston. tell us more about his message and what it reveals about the

divergences on differences in us policy in iran and the policy of say, uk, germany. we saw all of this play out when president macron was with trump. the line from mr macron and today from mrs may and from mrs merkel of germany, is that we need to keep the deal as is but we need to take into account the american concerns. we need to broaden the deal, and handset, if you like. renegotiated with the iranians and rein in their ballistic missile programme and so on. so, we keep seeing this

divergences between the americans and europeans. the americans feeling that the deal is way short of what they want and the europeans saying let's keep it, but that enhance it. mike pompeo was also talking about golf unity, what is not about? that's right. just one line and it might sound a bit bland and diplomatic, but deliverance by the new us secretary of state carries some weight. this was a reference to the long—running and damaging dispute between the gulf state of qatar and its neighbours. saudi arabia and others accusing catarrh of being too close to a run. they're very erratically isolated qatar. the

americans are wary of this. they don't like to see divisions in their allies. they want to see that rift being healed. if that was to happen, there would have to be a degree of compromise, a degree. no sign whatsoever, at the moment, but the saudis are ready to do that. injury slim, as we speak, there could hardly be a more welcome visitor injury slump than mr pompeo. the israeli leader has long railed against the steel. we may be just a couple of weeks from mr trump

walking away from the steel. the israelis will see mr pompeo as being exactly the kind of figure who they would like to push this forward. 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 11th 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 to it weeks ago. in the shop overlooking the spot where sergei skripal and his daughter were found poisoned on a park bench, they say some weeks takings have been down by 70%. to suddenly go from a busy walkway

and having a very busy shop to having almost no one in, it can go three hours with no one walking past, it is just a huge shock. i think everyone has found that difficult, but we have all come together and supported each other. yet at salisbury cathedral, visitor numbers have fallen by up to to 30% this month compared with the same period last year. some of that has been put down to the weather. they are hopeful that reassurances by government officials will finally start to get through. the start of the salisbury pub crawl. the latest event to try to persuade people back to the city. some want reassurance. it is 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 concerned about the children. my son walks through the town centre to school everyday. 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 that some good can come from the traumatic events. i believe we can look back in some years' time, but i can see years' time, i can see that we might see it as a turning point. many fear a return to normality may be a long way off. for the second year running president trump snubbed the white house correspondents' dinner last night. mr trump — well known for his turbulent relationship with the mainstream media — decided to spend time instead with supporters in michigan. andrew plant has more. a glamorous a—lister extravaganza.

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 michelin, instead. you may have heard i was invited to another event tonight, the white house correspondence dinner. but i would much rather be in washington, michigan then at the white house right now. mr trump was once stung here by barack 0bama who called mr trump "the donald" and ridiculed his belief in conspiracy theories. donald trump said it it is due to fake news

stories that he has chosen to forego the event. the correspondents association 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 will not be continuing the tradition. it is time now for a look at the weather forecast. here it is time now for a look at the weatherforecast. here is lucy martin. hello, the best of the brightness in the north and west today. in the south-east, it will be a wet and windy start. that area of low pressure moving up from the south, could bring some disruption to transport. that rain heavy, working its way north and west. it could fall as sleet or snow over high ground. away from it a lot of dry weather. but it will be chilly,

with temperatures falling below freezing. we could see a touch of frost to start the day. a bright start to the day for part of the country. for central and eastern parts, a bit more cloud. it will be windier. winds gusting over 50 mph. it will gradually move its way north and west. pushing through parts of the midlands, yorkshire and lincolnshire. in the north, we're looking at highs of 1a celsius. this is bbc news, our latest headlines: more than 200 mps have signed a letter coordinated by labour backbencher david lammy, sent to the prime minister, calling for government promises to windrush migrants to be written into law. south korea says kimjong—un has promised to close north korea's nuclear test site next month and has invited the world to watch.
