theresa may spent more than two hours with a last—minute talks with jean—claude juncker in strasbourg. they had a welter of documents and declarations, some of them legally binding. about how the irish backstop could be avoided with a future trade deal and how the uk might suspend it if there is a dispute with the eu will stop and there is a plan for how the two sides will agree alternatives to the backstop sides will agree alternatives to the ba cksto p by sides will agree alternatives to the backstop by the end of december 2020. enough, the prime minister said, that parliament could be reassured. mps were clear that legal changes were needed to be backstop. today we have secured legal changes. now is the time to come together to back this improved brexit deal and to deliver on the instruction of the british people. the president of the

european commission, jean—claude juncker, said he was happy to provide clarifications which it didn't change the substance of the agreement. he called this a second chance for the deal, but said they wouldn't be a third. in politics, sometimes, you get a second chance. it is what we do with this second chance that counts. because there will be no birdie chance. there will be no further interpretation of the interpretations, and no further assurances on the reassurances. what matters is whether this pile of paperwork convinces the attorney general, geoffrey cox, to change his view there is a risk the uk could be trapped in the backstop and how many mps are swayed as a result. the eu has helped, a bit, but isn't convinced any of this will work. that was adam fleming in strasbourg. in a few hours, the attorney general, geoffrey cox, will issue legal advice to the house of commons. mps will then have a chance for debate before voting

on what the government says is an "improved deal". our political correspondent, chris mason has been following events from westminster. this is now, for all of the detail, all the verbiage, a numbers game. how many people can this persuade here in westminster? let's be absolutely brutal about it, it could be tremendously successful in persuading an awful lot of people and still fail, because this is a hung parliament, the prime minister does not have a majority to call her own on so many matters relating to brexit, she has to persuade northern ireland's democratic unionist party who prop her up in westminster, and lots of conservative mps as well. now, tonight, plenty of them, including the influential and noisy brexiteers, who we have heard rather a lot of in recent months, people like steve baker, jacob rees—mogg, and others, they are saying let's give this a serious look. we should be fair to them. because as things stand, or they have heard is a statement from david lidington,

the cabinet office minister, and a press conference between the prime minister and jean—claude juncker of the commission, the documents have onlyjust appeared online. the documents to the non—legally trained eye, as adam was reflecting, are a little on the heavy side, particularly at 11:20pm. crucially, both sides will wait for the legal interpretation of the attorney general, geoffrey cox, and also the legal opinion that the european research group of conservative brexiteers are seeking themselves. to try and establish whether or not legally, in the view of mr cox and the lawyers, there has been a substantial change here. that was chris mason picking through the details. there is quite a lot to get through when it comes to brexit. and you can find analysis of theresa may's agreement with eu officials, on what they've described as "legally—binding changes" to the brexit withdrawal deal on our website bbc.com/news — or download the bbc news app.

let us leave brexit there. us aviation authorities say they believe the boeing 737 max aircraft, of the type that crashed in ethiopia on sunday, is airworthy. both black box recorders have now been recovered. the aircraft was flying to the kenyan capital, nairobi, when it crashed minutes after taking off from addis ababa, killing all 157 people onboard. our correspondent emmanuel igunza sent this report from the scene. it's a slow, delicate process of recovering pieces of the plane that might offer clues on why flight et302 came down. more remains of those who died have been recovered from the rubble, as rescue efforts enter the second day. the main focus for the investigators has been that huge crater that was made when the plane hit the ground. now, throughout the day, we've seen them pull out debris, including this mangled wreck

here of what remains of that aircraft. we've also seen them retrieve the black boxes, which will help in the investigations on finding out exactly what happened. there were people of more than 30 nationalities on the flight, including kenyans, ethiopians, canadians, and britons. at least 21 un staff were also killed. as the united nations conference began in nairobi, delegates remembered those doctors, aid workers, environmentalists, and academics who died in the crash. the un secretary—general antonio guterres spoke about the tragedy. our colleagues were women and men, junior professionals and seasoned officials, hailing from all corners of the globe and with a wide array of expertise. they all had one thing in common — a spirit to serve the people of the world and to make it a better place for us all. it's the second time this type of aircraft has crashed in five months.

in october, an indonesia lion airplane came down shortly after take—off, killing all 189 people on board. today, china and indonesia along with ethiopian airlines, grounded their fleets of the 737 maxss. recovery efforts are coming to an end but an investigation into what happened to flight et302 will continue for many months. emmanuel igunza, bbc news, bishoftu, ethiopia. our north america correspondent peter bowes in los angeles has more on what the us aviation authorities have been saying. they say this jet is airworthy, but they require boeing to make some software enhancements over the next few weeks. boeing have confirmed that since that indonesia crash at the end of october of last year they have been working on those enhancements to the software systems of this particular type ofjet and they will be implemented over the next few weeks.

so it seems that before this crash in ethiopia that work was in hands. and what the federal aviation administration, the aviation authority here in the states, is stressing is that it is very early days in terms of the investigation to see what happened over this past weekend. they say they need to see the data, they have not seen the data from the black box, they are sending investigators to work with people on the ground. boeing are doing the same. and that it is early days in that investigation. and clearly, at this stage, it is impossible to decide that whatever caused this particular plane to crash, the technical problems, if indonesia was technical problems, may not be the same as what happened in the crash six months ago. peter, we are in this strange situation at the moment when we have some airlines grounding planes, but others not. yes. on that list of countries grounding planes is growing by the hour. ethiopia, indonesia, china, brazil, airlines in those countries and others have decided to ground

this particularjet, whereas others haven't. and here in the united states the biggest user of this particular jet, american airlines, southwest airlines is indeed the biggest user of this particular kind of plane, they are continuing to fly. for the past 2a hours they have been operating normally. it remains to be seen how quickly these enhancements are made and the speed of the investigation. everyone will be hoping it moves very quickly. but there are critics, certainly of the aviation authorities here in the states, saying that this wait—and—see policy isn't good enough and that it could potentially lead to further loss of life is indeed these problems occur on another flight. peter bowes in los angeles for us. algeria's president, abdelaziz bouteflika, has bowed to weeks of mass protests by withdrawing his candidacy for a fifth term in office. but he also postponed the elections,

which had been due to take place next month. he said they would be organised after a national conference and referendum on a new constitution. his statement prompted a mixed reaction amongst protestors in the streets, as bassam bounenni now reports. algerians have not been unanimous in welcoming prezza abdelaziz bouteflika's statements. minutes after an announcement of a package including his withdrawal from the presidential race and the withdrawal of the announcement of the election that was set for april 18, young people took to the streets, but divided this time. some to celebrate, others to protest. opposition parties seen it dithering over the way to deal with this announcement. a former prime minister and prominent opposition

figure said protests were not only about abdelaziz bouteflika's bid for about abdelaziz bouteflika's bid for a fifth term in office, questioning the credibility of a transition period that should be led by his inner circle. others describe the presidential statement as a half victory, but reminding that the constitution does not allow the president to extend his own term, it exceptin president to extend his own term, it except in the case of war. algeria has witnessed one of the largest protests in decades. political uncertainty could prevail. but for now algerians are holding their breath. let's get some of the day's other news. president trump has unveiled his budget plans for next year, including a demand for more than $8 billion to build a wall on the border with mexico. it's far higher than the figure he requested last year, which sparked a dispute with democrats in congress. the row resulted in the longest—ever shutdown of the us federal government.

a belgian court has given a life sentence to a french jihadist who killed four people at a jewish museum in brussels in 2014. mehdi nemmouche carried out the shooting after returning from the conflict in syria. he was found guilty last week. an accomplice who was found guilty of supplying nemmouche with the weapons, received a 15 yearjail term. the inventor of the world wide web, sir tim berners—lee says global action is required to tackle what he described as the web's "downward plunge to a dysfunctional future". in an interview to mark its 30th anniversary, he said the cambridge analytica scandal had helped people realise how their data could be "manipulated". the venezuelan opposition leader and self—proclaimed interim president, juan guaido, has declared a state of emergency as the country enters its fifth day of power cuts. the cuts are affecting businesses and schools, which remain closed.

in some parts of caracas, people have been forced to collect water from rivers and springs. mr maduro blamed the power cuts on foreign sabotage and has promised deliveries of food, water and fuel. but the us says the power cuts are due to ailing infrastructure. with respect to the power outages, those are a direct result of years and years of neglect to the venezuelan energy system. you can talk to any international energy expert, they have seen it, the system has had problems for an awfully long time. their ability to get it back online has always present difficult. and over the past several years it has gotten worse. that was because of the blackouts that have taken place and my guess, without a little bit of engineering, will continue to take place. stay with us on bbc news. still to come: 50 years after neil armstrong's moon walk, a photographic celebration of our nearest celestial neighbour.

this is bbc news. the latest headlines: the uk government says theresa may and eu officials have agreed legally binding changes to the brexit deal. investigators have recovered the voice and data recorders from the ethiopian air crash. as more airlines ground the type of plane involved, us aviation officials say they believe it is airworthy. it's a war that's claimed 500,000 lives and made refugees of nearly 6 million people. this week, it's eight years since bashar al—assad's syria collapsed into conflict. many of those fleeing the fighting have taken refuge in neighbouring lebanon. many want to return, but fear both for their safety and for what they might find when they do as mishal husain has been finding out. many seasons have passed since the beginning of the brutal war that brought more

than a million syrians here. it is four years since i first met nura, who fled the fighting in 2012. she is still living in the most basic of shelters, her old life destroyed. are you thinking about going back to syria? when i last met the family, her teenage daughter, dalal, was already working in the fields. now, her younger sister, suriya, has joined her. they've been robbed of their education and the life they hoped for.

with the conflict now in a new phase, syrian refugees face difficult choices about when and if they can go home. in lebanon, most live below the poverty line. how many of you think you will go back to syria? all of you? but as i ask them when that might happen, doubts and fears emerge. what i've heard from syrians here is that returning now is not possible. some come from areas where there is still fighting. others don't know if there's any work available in syria. they fear being picked up

by the security forces or being sent into the army. all say that the syria they knew is gone. it's not only the bricks and mortar of the country that have been torn apart, but families and the very fabric of society. tonight, nura has managed to get through to relatives back home. she asks how the situation is. there's no stability, she's told, in the whole of syria. it's an answer that will keep her in lebanon for now. and in the camps here, many other families are caught between the hardships of refugee life and the risks of returning. mishal husain, bbc news, in the beqaa valley. families have told the bbc about how they've lost loved ones

to a bizarre cult. universal medicine was found to be a socially harmful cult by the new south wales supreme court. its main centre and leader, serge benhayon, is based in australia, but its european headquarters are based in a village in rural somerset. rachel stonehouse has been investigating. kasha clifford was 12 when she says her mum moved to somerset to follow universal medicine. one of the main things i can remember was turning everything anticlockwise, because if you didn't, then you would let entities in. so, it was like, cooking food had to be done anticlockwise, things like that, turning doorknobs and handles. i was sitting here, my dad was over there. my mum came upstairs and she started burping ridiculously, and he was like, "what are you doing?" and she said, "i'm just burping out bad spirits." universal medicine was founded in australia in 1999 by bankrupt tennis coach

serge benhayon. in october, an australian civil court found the organisation to be a socially harmful cult, and serge benhayon a dangerous charlatan. among other things, he claims that people have been sexually abused because of what they did in their past life. if you have been sexually abused, then you have been an abuser. he says those with autism were former dictators. down syndrome, or are past—it, or any other disabled child. he teaches that alien—like creatures seek out vulnerabilities by smelling us. fact — and that happens everywhere. you can be on a train, on a bus, you are being smelt all the time. twice a year, he holds workshops for followers in the lighthouse, in tytherington near froome, where universal medicine's european headquarters is based. nina foy has lived in the village for 30 years. she says it's changed since serge benhayon brought universal medicine here. it does concern me, because i think they prey on vulnerable women, because it mainly seems to be women.

you see people walking through the village like zombies. follower simon williams is the managing director of the lighthouse. he's also the president of frome chamber of commerce. he didn't want to be interviewed on camera, but we had a 20—minute conversation. he did admit that he is a follower of universal medicine, that serge benhayon is a great friend of his, who he loves very much, and that the court ruling in australia is totally untrue, none of it is true. and when i started to question him on some of serge's beliefs around disabled children and victims of sexual assault, he refused to answer that, and at that point, he asked me to leave and said the conversation was finished. serge benhayon has always denied running a cult and any wrongdoing. rachel stonehouse, bbc news, somerset. this summer will mark 50 years since neil armstrong became the first person to walk on the moon. now, a new york museum is looking at how humans have captured the moon in photographs.

photography has always been something where you are trying to capture a single individual moment. photography was, for one thing, indispensable in planning the missions to the moon. we had to make sure that we knew what the surface was like, we had to make sure that we knew where you could land, they made sure that when they landed, they were not in a place that might have recently been in shadow, so it would be too cold, or in daylight for too long so it would be too hot. the eagle has landed. ranger 9 was a mission to launch something at the moon and see if they could actually strike the surface, see if they could navigate that accurately, and it took these images as it was heading in, and you can see it's getting closer and closer and closer. that's the last image

that it returned before it smashed into the surface. this exhibit is called a century of lunar photography and beyond because these are actually more than a century old. these images were taken by a specialised telescope at the paris observatory, and these are standard surveys where they would take this image, take another one a few months or a few years later to see if anything had changed. i just love the texture of these, they‘ re really, really beautiful prints. some of the images that we have in the gallery are notjust images of the moon, but images comparing the earth and the moon, and it is interesting that we have this really strong desire to look back and record images of our own world. so, one of the things which happened when we went to the moon, the astronauts said, is that they basically discovered the earth by stepping outside of the earth and seeing it from far enough away that you could block it out with less than the palm of your hand.

that allowed them to see the earth as a small, fragile, unique object surrounded by basically infinite deadly nothingness. this is very close to what they saw looking through their visor, and the idea that we can explore a place where no human being had ever been and we can bring back images that make you feel as if you're there, that's sort of a revolutionary idea, i think. amazing images. marking 50 years since neil armstrong became the first person to walk on the moon. theresa to walk on the moon. may has insisted legally binding theresa may has insisted legally binding changes she has secured to have brexit deal are enough to address some concerns about the controversial irish backstop. you can reach me on twitter. i'm @lvaughanjones.

you are watching bbc news. i will be back with the headlines in a couple of minutes. hello there. although it was quite windy out there on monday, it was probably the quietest day of this week. through the next few days, the rest of the week, we're going to see some outbreaks of rain, which will be heavy at times, and accompanied by some very windy conditions. in fact, we've got a storm on the way. the latest storm is being named storm gareth, and it's around that curl of cloud there, already pushing ahead this thickening cloud to bring some outbreaks of rain, and on and ahead of those weather fronts, we've got some strong and gusty winds, as well. but it's really as the storm, the low centre, approaches later on on tuesday and into tuesday night that the winds really start to pick up. so, this is what we look like early on in the morning. those are the sort of temperatures — pretty mild out there. that's not the main story, mind you. you can see we've got that band

of rain around from that cloud, and these are the sort of gusts we're looking at early in the day, so gales, i think, in many places. and it could be particularly squally, briefly, in that rain band, as it sweeps its way across northern england, wales and the south—west of england in the morning, into the south—east of england through the afternoon. we may well find some sunshine and showers following on, and the winds easing just a little. but then they really start to get noisy again around that swirl of rain, around our storm that approaches the north—west later on in the day. and we're drawing down some chillier air as the day goes on, so temperatures will be dropping a bit. the winds, though, really picking up through the afternoon, into the evening and overnight in northern ireland, western parts of scotland. 70, maybe 80mph around some coasts, and we've got that rain around, too — that'll push its way into england and wales. 50—60mph gusts quite widely. very slowly, the winds easing down just a little bit on wednesday, but still a very windy day, and there will be some sunshine and some showers, before we get some more persistent rain coming back

into northern ireland. those temperatures should be a little bit higher, typically in double figures. now, our storm is heading across the uk and out into the north sea, so the winds are easing down a little bit. but then we've got that next weather system coming in rapidly from the atlantic, which you can see overnight it brings rain in many areas, that weather front then sinking its way southwards on thursday. some of the heaviest rain likely to be over the high ground in north—west england. you can see we've got some strong to gale—force winds, and then by friday, sunshine and some showers. the strongest of the winds, though, arriving with storm gareth later on on tuesday. through tuesday night and into wednesday, there's likely to be some travel disruption and some damage. you can keep up to date with the forecast here, and all the details on bbc local radio.
