good evening and welcome to the bbc news at six. withjust 11 days until the uk is due to leave the european union, the brexit process has been thrown into confusion and disarray after the prime minister was told she can't now bring her brexit deal back before mps for a third vote — unless there've been substantial changes to it. in a twist that took downing street by surprise, the speaker of the house of commons, john bercow, said he was following parliamentary rules which date back centuries. our political editor laura kunessberg is in westminster. the prime minister has tried twice and failed to get her brexit compromise with the eu through parliament. and she was hoping, despite the many challenges to have another go, and make it third time lucky before the end of the month. a john bercow, the speaker, who is in charge around here, stunned this place by, at half past three, saying that she could not have another try, invoking the ancient rules of this

place to say the government cannot keep bringing the boat back and back again. there is some surprise, and real questions about what happens nextin real questions about what happens next in this whole process. but one government minister told me the speaker was breaking the constitution. time is not healing, it is hurting. every day, it seems theresa may's task gets harder and harder. arriving at the back gates of number 10 today, she planned to have another go at getting her deal through. not knowing what the speaker had up the sleeves of his black gown. order. iwish speaker had up the sleeves of his black gown. order. i wish to make a statement to the house. john virgo has the ultimate power in parliament and, as it stands, he says the government cannot try again. —— john bercow. what the government cannot legitimately do is to resubmit to

the house the same proposition, or substantially the same proposition as that of last week, which was rejected by 149 votes. in other words, the government should forget it, he says, if they think they can just keep asking mps to vote again and again on a brexit deal because it has been lost twice before. order. yes, indeed. point of order? you can hear the surprise at his ruling and see government front benchis ruling and see government front bench is jumping up ruling and see government front bench isjumping up to ruling and see government front bench is jumping up to try to push back. we are in a major constitutional crisis here, a political crisis that we want to try to solve for the country. the prime minister is doing everything she can to try to break that impasse. the chair‘s ruling is the chair‘s ruling and it is binding. but i simply ask the question, what can parliament do to help end the uncertainty? the speaker's to help end the uncertainty? the spea ker‘s many detractors to help end the uncertainty? the speaker's many detractors suggest he is using his powerfar too aggressively. stopping parliament having another say on brexit. his fa ns

having another say on brexit. his fans would argue he is doing exactly the right thing. strangely, the move has united some levers and remainers who both want to stop the prime minister's deal. what was the point in having another week ploughing away on an agreement that it was not going to get through? it is the week of the council, so she can go to the council and open up new and exciting grounds. we know these european deals also happen at the last minute, so something can come out of this. it is claimed she cannot keep flogging the same dead horse now, and she has been doing that for ages. let's get on a different horse. there is anger, too. i think that what will happen, thanks to this announcement, brexit will not occur, and the people of britain, both of those that voted to leave, and the remainers that want to see democracy done, they will be absolutely furious that their views have not been allowed to be heard in the house of commons. there was holed up in number 10, still trying to get their deal over the line, had

no idea this was coming. the mood has turned sour. for me, treating collea g u es has turned sour. for me, treating colleagues with courtesy and respect is at the forefront of that reform. any speaker's is at the forefront of that reform. any spea ker‘s council would is at the forefront of that reform. any speaker's council would have to have that at its heart. i am not confident that would be the case. well, so be it. itreat confident that would be the case. well, so be it. i treat the house with respect. respect? there is not much of that around. a cabinet minister told me the government would just have to find a way around the decision. but none of this has been done before. there is no map, no easy route out. it is far from straightforward to see how the government might go can get its deal back on the table and have another chance to give mps a say. that said, it is not impossible. i can imagine government ministers and government lawyers will be racking their brains to think, can they change the words of what they wanted to put on the table in black and white. could there even, if it would be more dramatic, suspend parliament and start a session again after a couple

of days, essentially restarting the process ? of days, essentially restarting the process? but that would be pretty drastic. and there is an awful lot of head scratching in parliament at such a serious and vital time for oui’ such a serious and vital time for our politics. and i think many of oui’ our politics. and i think many of our viewers watching will feel very frustrated. number 10 believes that there is a huge public demand to get this done, to get it out of the way. sophie, remember, at times like this, it is absolutely obvious we do not have a written constitution. what this place has is a rule book, and it is up to the speaker to interpret those rules. and, whatever else you can imagine is going on with all of the politics, both high and low, that is what has happened. this is an interpretation of the rules thatjohn bercow is absolutely entitled to give, no matter how much it drives the government around the twist, and makes people worried about what is next. police in northern ireland are

investigating the deaths of three teenagers at a st patrick day's party last night. a 17—year—old girl and two boys aged 16 and 17 are thought to have been crushed in a large crowd at the entrance of the hotel in cookstown in country tyrone. our ireland correspondent emma vardy has the latest. this was the scene outside the hotel's nightclub as the crowd waited to get in. people began to scream that they couldn't breathe. there was confusion and disbelief as one teenager died at the scene and two died later in hospital. terrible. terrible, just chaos. young ones, hysterical. a 17—year—old girl who was killed has been named as lauren bullock. her school described her as shining light. deeply saddened at the tragic death of lauren, our year 13 student. she was a beautiful girl, a young person with much talent and much capability.

one of the two boys who died has been named locally as connor currie. today, local youth clubs offered young people support. 17—year—old kyra says she watched as people tried to resuscitate her friend on the floor. i just was with my friends and ijust started crying, just having to see everybody there depressed and having to see him laying on the ground and that. why do you think it became such a crush? i don't know, i think everybodyjust wanted to get inside and drink, it is what everybody wants to do. police have appealed for people not to post pictures of the incident on social media, but to get in touch to help piece together what happened. there was a crush towards the front door and in that crush, people seem to have fallen. we are examining now to see if the people who had fallen are the deceased. there was a little bit of struggling going on to get people up off the ground and that might explain also why there was a report of some fighting. emergency services have described

what happened here is a truly appalling incident and, today, there are questions about how the event was advertised and how the crowd was being managed outside. staff at the greenvale hotel are assisting police with their inquiries. there are calls to look at what lessons can be learned from the st patrick's day which turned to tragedy. emma vardy, bbc news, cookstown. new zealand's prime minister says she will announce detailed reforms to the country's gun laws within days after friday's attack on two mosques which left 50 people dead. clive myrie is in christchurch for us now. yes, the prime ministerjacinda ardern has said her cabinet backs changes to gun laws in principle. police say the killer brenton tarrant used military—style assault weapons which had been modified to make them more deadly, which is not illegal under current legislation. our correspondent hywel griffith reports on the day's developments here in christchurch.

hosne, shot while saving her disabled husband. mucad, a three—year—old remembered for his smile. and sayyad, a high school student at the mosque with his mother and friends. it's the stories of the victims, and not the gunman, that new zealand wants the world to hear, as it faces the question of whether they were failed. abdigani would have been at the mosque if he hadn't overslept. but his housemate, mohammed, was there, one of 20 friends he lost as the gunman kept on shooting. women and children have died, you know? a very cowardly act, i would say. we're coping the best we can. he's not succeeded. if anything, this will bring us a lot more closer, and we still have our faith, which he can never take away from us. within hours of friday's terror attack, new zealand's government

pledged to reform gun controls. the suspect, brenton tarrant, had five weapons, two of them semiautomatics. after the 1996 port arthur massacre, australia banned semiautomatic weapons and held a national amnesty. new zealand may now follow. the prime minister says measures have been agreed in principle. when australia found itself tragically in a similar position to what we find ourselves now, they took 12 days to make their decision. we have taken 72 hours. there is still some detail that needs to be worked through. i want to do that, but still move as quickly as we can. just as in australia, just as in america, it's taken a terrifying, violent act to provoke a debate on new zealand's gun laws. but, just as in those of the countries, there is a powerful gun lobby here, likely to resist change.

the christchurch gunman bought four firearms online within four months, from this company. its store in the city remains open, and its owner defiant. he was a new purchaser, with a brand—new licence. it was an ordinary sale. and while he was keen to go before the cameras, he wouldn't answer our questions on restricting gun sales. i totally agree there should be a gun debate. but today is not the day. please respect me on this. i am going to leave if these are the only questions you have. on wednesday, a mass funeral will take place for many of the victims. families have been desperate to arrange burials in line with islamic custom. the need to honour the dead, to cherish their memory, is what now sustains this place. hywel griffith, bbc

news, christchurch. people here continue to remember those who lost their lives and the scores of people still in hospital recovering. a particular focus today has been the children who died in the two mosque attacks and young new zealanders have been gathering together to see how they can help help their community. this silent memorial shouts its poignancy. 50 pairs of white shoes. for the 50 people who died. among them, little children. as so many reflect on this tragedy, lost in a world of painful thoughts, it is sobering to remember that the killer didn't see human beings in those mosques. he saw targets and children were fair game. the tributes right across christchurch reflect that abomination.

five perished who were under the age of 16, including a three—year—old and a four—year—old, given no chance in life. sayyad milne was 14. now at peace, says his father, and mourned by one of his best friends. in the morning, the news was confirmed and i was devastated, it was awful. he was known by so many people and loved by so many people and it is so sad that this community has been brought down by this shooting and it is awful, yes. i don't know what to say, really. no one knows what to say. but ocirano talaier, who is 17, says it is important young people have a voice in helping a community heal. i know that my school has been majorly affected. many students have lost loved ones and just making sure that they know

that the school is behind them and, you know, getting involved in the events i've led just shows them that, you know, hatred cannot drive out hatred, only love can. and this is the fruit of his labour, organising a huge vigil. an opportunity for thousands of young people to celebrate life. i think it's amazing how we all gathered together to show our support and especially how it was done by kids in high school students, i think that isjust a really good thing. local schools now have counsellors on hand to help traumatised children out of a calamity. after the calamity. recognition that no one should have to walk through gates of grief and sorrow, especially the young.

what an incredible bunch of teenagers there, truly impressive and that young man, okarina tilia, i spent 40 minutes with him, truly impressive and fast becoming one of the faces of reconciliation here, trying to bring back together a community that are terrorist gunmen tried to rip apart. remember, preparations are still under way for some of those funerals. we expect the first could take place as early as wednesday but potentially further later in the week. we are expecting the majority of those families who lost loved ones in this appalling charity to —— tragedy to bury their dead. back to you. clive, thank you. our top story this evening. drama in the house of commons as the prime minister's told there'll be no new vote on her brexit deal unless there are substantial changes. and still to come, bringing home the cup, the wales rugby team prepared to meet crowds in cardiff following their grand slam victory at the

weekend. coming up on sportsday on bbc news for you, rory holds on. his year—long wait is over, he wins the players' championship. parts of southern africa have been hit by a devastating cyclone, with fears that thousands of people may have lost their lives. cyclone idai has reached speeds of up to 120 miles an hour and brought with it torrential rain. the countries worst affected have been mozambique and zimbabwe. idai came in off the indian ocean at the port city of beira, which has been largely submerged underwater, before making its way into zimbabwe. our reporter shingai nyoka has managed to get to chimanimani close to the border and has just sent this report. shops with their fronts torn off, windows shattered in the street. the roofs rendered useless,

ripped from theirjoists. this is beira, where it is thought there has been the greatest loss of life. while the damage on the ground is bad enough, it is from the air that you can see the scale of what has happened here. beira is the major port on mozambique's coast. now it's largely underwater after the cyclone tore through it, bringing the sea in its wake. the city's tightly packed suburbs are submerged. no one knows yet of the true loss of life here. translation: flying sheets of metal decapitated people. some people are in hospitals. it's really bad. we don't eat properly, we don't sleep properly. we have no home. from the suburbs, cyclone idai's destructive force spread inland, no respecter of borders, it crossed into neighbouring zimbabwe. landslides, rock falls and raging waters have marooned hundreds.

as you can see, the devastation of cyclone idai, there is a major crater here. now this is one of the main access roads between the city of mutare, where the support teams and the supplies are, and the villages of chimanimani, which have been cut off. we met an elderly couple who were trying to check on family members on the other side. he tells us he's been trying to call his family, trapped in chimanimani, to find out if they survived the storm but he hasn't been able to reach them. his wife miriam makes the sounds that that the wind and water made as the storm approached. she says the rains have been relentless. five million people were in need of food aid before the floods. this makes matters so much worse. shingai nyoka, bbc news, chimanimani, eastern zimbabwe. police in the netherlands say they've arrested a man after three people were shot dead on a tram in the dutch city of utrecht.

five others were hurt when a man opened fire at a tram stop not far from the city centre this morning. it sparked a manhunt as police tried to find the gunman. an arrest was made in the past hour. damian grammaticas is there for us now. sophie, yes, this is where it all happened, the man with a gun at this tram stop in utrecht shooting people. as you were saying, three dead, five injured was the toll here. all day, police kept people indoors, children in schools, people in offices here, as they hunted for the man. it seems he was known to them. what is not clear is whether this was an act of terror or whether he was targeting specific people, perhaps a family feud. but it all began here at about 10:50am this morning. sirens. late morning, a tramline at a standstill and dutch medics scrambling. the reports were of multiple casualties. armed police units responded fast, too.

they moved in as well, hunting at least one attacker who it was thought was still nearby. dan molinar was in the tram. he says all of a sudden, the shooter game running, waving a pistol in the air. "i thought, i had to get out of here." what eyewitnesses said was that this morning on the tram, a man pulled a gun and began shooting. there was panic as people tried to escape the scene and, within minutes, police and ambulances were here but it is thought that he fled around the corner and now police have a house surrounded in one of the adjacent streets. erwen van der linden was just getting ready to catch the tram himself when it all happened. i heard a lot of screaming, i heard a lot of honks from the cars then, all of a sudden, sirens and hell broke loose. it was chaos. soon, several city blocks in utrecht had been sealed and police issued this picture,

of the suspected attacker, gokmen tanis, 37 years old and originally from turkey. anti—terror teams thought it might have led just a few hundred yards around the corner. as they tried to track him, they ordered people in the area to stay indoors. offices, schools and universities all in lockdown. "this has been a jolt for our country," the dutch prime minister mark rutte said, adding, "we are horrified and in disbelief". and late in the afternoon, the suspect gokmen tanis was detained. the police siege at an end but the sense of shock here still deep. damian grammaticus, bbc news, utrecht. eurostar is urging passengers to avoid travelling until after wednesday unless their journey is "absolutely necessary". the cross—channel rail operator warned that industrial action by french customs workers, who are demanding more pay and resources ahead of brexit, will continue to cause delays.

eurostar is offering a free ticket exchange or a refund. a woman has been sent to prison for at least 18 years after being convicted of drowning her daughter in a bath. winchester crown court was told that claire colebourn, a former biology teacher from fordingbridge, in hampshire, killed three—year—old bethan after her marriage broke down in 2017. large crowds are expected on the streets of cardiff tonight to celebrate the welsh rugby team's grand slam victory at the weekend. our sports correspondent katie gornall reports. it's been a weekend to remember for the grand slam champions. for the past three days, they and their country have been in party mode. now at the welsh assembly in cardiff, it was time for a more formal celebration. to see the turnout today, you can see how much it means to everyone and it is nice to put a few smiles on faces. it is nice to be here as well.

with a little dink. hadleigh parkes! wales' match with ireland was meant to be a nailbiter. instead, they blew them away 25—7, suffocating them in defence and punishing them in attack. never did they look like anything but winners. they haven't had it all their own way in the six nations, but even when they were behind against england and france, they found a way back. when the pressure is on, wales have proved themselves to be masters of the big moment. their demolition of ireland gave warren gatland a record third grand slam title in his final six nations game in charge. his side are now on a 14—match winning streak and climbed above ireland to second in the world rankings. they will travel to the world cup in japan later this year as a major title contenders. as major title contenders. i think mentally, they are strong, they have great leadership on and off the field. they have beaten everybody apart from new zealand, so i'm sure they will be cautiously optimistic. excellent chance now. i mean, we are second in the world now. where do you go from here? only up.

it is notjust good from wales, it is good for the whole country it is notjust good for wales, it is good for the whole country and other parts as well. it is putting us on the map. there is a togetherness about wales, a sense that when you play them, you play a nation, not a team. this is a small country that believes it can conquer the world. and there is a sizeable and very buoyant crowd here at the welsh assembly. the players, the staff, just there with the trophy on display as well and you have to say, really, when all of those dies down, attention will inevitably turn to the world cup and wales are now in the world cup and wales are now in the best shape of all of the northern hemisphere teams. ireland we re northern hemisphere teams. ireland were made to look ordinary by them, england have been accused of being mentally fragile by their own coach whereas wales, in the words of warren gatland, have forgotten how to lose and how they would love that to lose and how they would love that to stretch all the way to a world cup final to stretch all the way to a world cupfinal in to stretch all the way to a world cup final in november. thank you. time for a look at the weather. here's nick miller. and a lot of water around.

yes, so much rain, flooding in york and at the met office says northern ireland has seen its wettest march on record and it is only the 18th, but there is a weather change on the way this week and for many others, it is going to settle down. it is not going to be bone dry or flat calm, but much less stormy than we have seen of late and it is all down toa have seen of late and it is all down to a change of the position of the jet stream. it has been coming right at us with deep areas of low pressure and is lifting to the north, which allows high pressure to building across more of the uk for the next few days and that means things are going to be settling. we haven't got there yet and more of us haven't got there yet and more of us have seen rain today, though not as heavy as recently but damp and drizzly with a good deal of cloud around overnight. some clear spells across the east and south—east of england but there could be some fog patches. it is eastern areas that get the lowest temperatures, close to freezing in the coldest spots but most of it at around 4—7d. tuesday begins again with a lot of cloud

around. not as much blue, rain, showing up, but still damp in some spots and heavier bursts in northern scotla nd spots and heavier bursts in northern scotland on a stronger win compared to today. elsewhere, winds are fairly light, some sunny spells here and there and notice temperatures are edging up a little bit. that is asa are edging up a little bit. that is as a slice of milder or even warmer air is coming our way for mid week. the colours represent the warmth, not necessarily the sunshine. let me lower your expectations, there isn't going to be a huge amount of blue sky but it will be mainly dry and a few sunny spells coming through. all the while, northern scotland close toa the while, northern scotland close to a weather front so they will see rain at times, breezy compared to elsewhere, but notice the temperatures are heading up, into the high teens in the warm spots. mainly dry until the end of the of the week, the winds pick up again in scotland, a bit cooler into the weekend but for the moment, a hint of spring a reminder of our top story... coming back.

thank you. downing street is taken by surprise as the prime minister is told she cannot bring her brexit deal back to the commons for a third vote unless it is substantially different. that's all from the bbc news at six, so it's goodbye from me and, on bbc one, we nowjoin the bbc‘s news teams where you are.
