this is the briefing, i'm samantha simmonds. our top story: after the eu agrees theresa may's brexit agreement, the prime minister is today trying to convince parliament to back her deal. i'm philippa thomas in westminster, where opposition mps and many in her own party say they won't back the agreement. russian special forces seize three ukrainian navy vessels off the coast of crimea, in a sharp escalation of tensions. after six monthes in space, the nasa insight spacecraft is due to make its final descent onto the surface of mars. a warm welcome to the programme, briefing you on all you need to know in global news, business and sport. and you can be part of the conversation. have you been waiting for cyber monday, or did you nab your bargains on black friday?

are there any genuine deals to be had? what is the best discount you have found? i know i've been shopping this weekend. do get in touch. tell us what you think. just use the hashtag #bbcthebriefing. so, after all the negotiating, the drafts and then the redrafts, it seems to have come down to a straightfoward choice. it is her deal, or a no—deal brexit. that is what theresa may will repeat to mps in the house of commons later, as she tries to unite them behind the draft withdrawal agreement. let's go to westminster and philippa thomas. good morning, samantha. yes, theresa may has already started her pr tour. she has a very clear message, doesn't she? she says this deal will allow britain to take control of its

borders, it's money and its laws. no matter that other people are saying, critics are saying, it means we still need to take rules from the eu while we are in the customs union. other critics are saying this will really damage the british economy. she says this is what the people of reason voted for in that referendum in 2016. -- reason voted for in that referendum in 2016. —— people of britain. so she now has to try to get a deal through parliament, through westminster, and in the coming hours we are going to hear a lot of debate back and forth about whether that is possible. because already some of her own mps as well as opposition mps have said they are not going to back this. alex forsyth has more. theresa may a right turn yesterday with the ink fresh on the deal that will take us out of the eu. in brussels, she got the backing of eu leaders. now she must sell it to sceptical mps and the public. there we re

sceptical mps and the public. there were those who said that reaching a brexit agreement that worked for both sides was an impossible task. from the start, i rejected that counsel of despair and set about negotiating a deal that worked for the uk and the eu, one that delivered on the result of the referendum and set us on course for a prosperous future. there are two parts to this deal. the withdrawal agreement deals with our exit. there will be a transition period after we leave in march when not much changes until december 2020, so new arrangements can be worked out. it settles the divorce bill and guarantees the rights of eu and uk citizens living abroad. and it contains that controversial backstop plan to avoid a hard irish border if there is no trade deal. then there isa there is no trade deal. then there is a political declaration, which talks about an ambitious future partnership in trade. free movement will end. but the details haven't been agreed, and this document isn't legally binding. the prime minister

and other eu leaders say this deal is the best it gets. back home, many disagree. what she's created satisfies very, very few people, so the chances of getting this deal through parliament, i think tom is effectively nil. here, all the opposition parties and many conservative mps have said they won't support this deal. so the challenge for the prime minister is to try and win them around for a crucial vote in a few weeks. —— before a crucial vote in a few weeks. so what happens next, now that the brexit deal has been endorsed by eu leaders? the biggest potential hurdle lies at westminster, and mrs may's chances of getting the agreement through parliament next month. if mps approve it, it would then be put to the european parliament. but if, on the other hand, it is voted down by mps, there are a number of possible consequences. they could try to force a a renegotiation, a general election, another referendum, or we could leave without a deal.

the european commission president, jean—claude juncker, addressed what would happen if mps rejected the brexit deal. he was speaking to our europe editor katya adler. this is the best deal possible for britain. and this is the only deal possible, so if the house would say no, we would have no deal. it's not the intention of the prime minister nor of the cabinet nor of the parliament to go for a second referendum. this is the deal — this is the deal. and you are trying to help the prime minster sell it, actually, by saying this is the best deal possible. but surely it can't be the best deal possible, because right from the beginning, you and other eu leaders said it has to be very clear in this deal that life on the outside can't be as good as on the inside? if you're out, you are out —

you are not part of the decision—making process. this is, by the way, a very sad moment for the european union and for britain. and we will discover in future years why i say today that this is a sad moment. i'm not happy, but i'm happy that we have a deal. there is a perception in much of the uk that this was a punishment process, the negotiations process. that even though today there were nice words for theresa may, like from the dutch prime minister, she negotiated in a very tough way — that actually, in the end, the uk had to concede most of the time. i do not understand why the british people, and i like the british people for so many, including historical reasons, why they are feeling that they are humiliated. i don't see that, because numerous points of view of the british have been taken into this deal. so this is not a humiliation for britain. he said it was a very sad moment for

him and many in the eu, and in britain it is such a narrow vote. almost 52% voted to leave the european union, but 48% voted to stay. so we still have a very divided britain, as well, and for those who felt we should go and that 29 march is a great day to look forward to, well, many of those voters and those members of parliament feel that this deal doesn't actually give them what they wanted, what they felt they voted for. so there are not many people who are very happy here, which is why theresa may has to keep on saying this is a deal that will offer a brighterfuture, saying this is a deal that will offer a brighter future, and saying this is a deal that will offer a brighterfuture, and she will keep on repeating that mantra about it giving us back control of oui’ about it giving us back control of our borders, our money and our laws. we are going to hear that again and again. let's brief you on some of the other stories making the news: mexico says it will deport a group of migrants who forcefully attempted to cross the border

into the united states near the city of tijuana. the government said some of them incited violence and encouraged others to run towards the fence that separates the two countries. the ugandan president, yoweri museveni, has said the operators of an unlicensed vessel which capized on lake victoria will be prosecuted. at least 29 people are known to have died and many are still missing. the vessel was designed to transport 50 people, but is said to have been carrying 120 passengers. turkish riot police fired tear gas to halt an unauthorised march in istanbul marking an international day calling for an end to violence against women. the police moved in after the crowd ignored calls to stop the march. peaceful protests were held in many other cities around the world over the weekend. up to 145 pilot whales have died after becoming stranded on a remote beach near the southern tip of new zealand. officials said half of the mammals had already died by the time they were found and then they decided to euthanise the rest due to their deteriorating

only way in and out of the azov sea, which ukraine and russia share. russia says three ukrainian vessels illegally entered its waters. first it blockaded them, then it fired at them. ukraine says six of its sailors were hurt, while the russian security service says only three we re security service says only three were wounded and were getting medical care. in kiev, ukraine's president, petro poroshenko, described the russian actions as unprovoked and crazy. mps they will vote on whether to introduce martial law on monday. translation: martial law on monday. translation: martial law would be introduced in order to strengthen ukraine's defence capabilities, amid increasing aggression and according to international law, a cold act by the russian federation. it does not mean oui’ russian federation. it does not mean our refusal to resolve the issue i political and diplomatic means. we intend to adhere to all international obligations including the minsk agreements. ukraine's key

ports are in the azov sea, but since russia annexed crimea four years ago, it is able to block access in and out of the kerch strait. overnight in kiev there were protests outside russia's embassy. these events like assault in words that have not healed. both sides have asked for an emergency meeting of the un security council, which will be held on monday morning, the hope being that this crisis doesn't escalate any further. stay with us on bbc news. still to come: it has been rescheduled twice because of fan violence. when will boca juniors play river plate in the copa libertadores final? president kennedy was shot down and died almost immediately. the murder ofjohn kennedy is a disaster for the whole free world. he caught the imagination of the world. the first of a new generation of leaders. margaret thatcher is resigning

three ukrainian navy vessels off the coast of crimea, in a sharp escalation of tensions. after the eu has agreed theresa may's brexit agreement, the prime minister is today trying to convince parliament to back her deal. let's stay with brexit and back to my colleague philippa thomas at westminster. after everything that happened in brussels and the speed with which that deal was signed off by eu leaders now we are really into the uncertainty. i will be totally honest, we do not know what is gained to happen but we have some options. the professor of government at lsejoins me. options. the professor of government at lse joins me. we do not know and there are lots of things we will find out as we go along the process. theresa may signed everything in

brussels yesterday and the action comes back here. there will be a vote on this deal. as of now, it looks as if there will be enough conservative mps voting against it. the question is what happens next? will there be an opportunity for mps to amend this proposal? will that allow portal to then be able to vote for something else, perhaps a second referendum or a different kind of deal, not much time to renegotiate that. lots of options and still the possibility of no deal at all and britain crashing out. it was made very, very clear byjean—claude juncker that this is the best deal, he said this is the only deal. he

would say that. it is in negotiation. his sound really convinced. his sound convinced that oi'i convinced. his sound convinced that on the other hand, mrs may was not far short of winning and went back to brussels and said i nearly one these vote. we are near the 29th of march, mps will be worried a hard brexit, could they change their mind. that is a possibility. but before that, mps may find a way of amending whatever motion is put to them. it could then we opened a bigger canon of worms back in brussels. what nearly wants to avoid is what you refer to as a cliff edge. you could do damage to both the british and european economy. figures this week coming up from the

treasury, the latest of how different kinds of brexit might affect the uk economy. it is unlikely any of those forecast are going to be for a smaller economy. that would described as project fear by those who support brexit but in the end, the uncertainty going on and on and on must mean there is less investment and the economy is growing more slowly and that is a reality. tony travers, thank you very much. we will be talking about the implication of a no vote in the next few days because of this vote is likely to happen... possibly around the 10th of december for the 12th for the vote which in the writ wraps all this up, assigns it off,

but we absolutely cannot be sure of that and frankly anything could happen. a spacecraft launched by nasa, six months ago, will attempt to land on mars later. the probe, called insight, carries a number of instruments to explore the internal structure of the planet. from mission control in pasadena here's our science correspondent, victoria gill. they call it seven minutes of terror but this last stage of the journey to mars, the insight lander would need to sell itself down from 20,000 kilometres per hour to a safe landing speed. this is the full—size, life—size model of the insight land. it will power everything on the lander. doing amazing sights on the surface of mars. we are giving it its first

checkup in a million years. the pressure of a safe touchdown will trigger a beacon to be sent back to earth, it is first call home. once we land, we get a message back from the spacecraft and then we have to check on the spacecraft and when we get that first indication our hearts arejust going to get that first indication our hearts are just going to explode. it will be really exciting. its robotic arm will put down a monitor, detecting any vibrations. this will be the first robot to drill deep into the surface, in an effort to understand the structure of this planet. surface, in an effort to understand the structure of this planetm surface, in an effort to understand the structure of this planet. it is a kind of like a meditative spacecraft. sitting there and listening for quakes. all these other instruments have centre stage but now we are going beneath the surface. we have only scratched the surface. we have only scratched the surface previously. these

measurements will allow scientists to step in time and work out how rocky bodies like mars, earth and the men formed 11.5 in years ago. something of a tradition at mission control, the whole team it's peanuts because on the seventh attempt, when it finally was successful, the chief engineer was eating peanuts. just another small detail to help this spacecraft lands on mars. very exciting and we will bring you all the details of when it doesn't land, fingers crossed. now it's time to get all the latest from the bbc sports centre. hello, i'm tulsen tollett. coming up in your monday sport briefing: newcastle and burnley both look to pull away from the relegation zone when they meet in the premier league later and the boston celtics will look to turn their nba season

around when they face the pelicans in new orleans. rafael benitez has every reason to hate this week's fixture list. newcastle united have lost 11 of their last 12 premier league monday games. if the stats are anything to go by then victory away at burnley might be a tall order. after a shaky start to the season though newcastle are on a bit of a roll. they've won their past two games but did the international break come at the wrong time? i think sometimes it is true that when you are doing well, the international break changes everything and sometimes when you have injuries it is you more time for players to recover so you have to ta ke for players to recover so you have to take it as it comes and hopefully you can carry on winning. as a say, it isa you can carry on winning. as a say, it is a long—distance race and we started walking, and now we are running and hopefully we can then sprint. despite making the eastern

conference finals last season, the boston celtics have failed to fire so far in the nba this campaign. saturday's defeat to the dallas mavericks was their 10th of the season. this layup from kyrie irving kept them in the game, but he missed all five of his 3—point attempts. boston need to be on target later when they face face the new orleans pelicans. sunday's rescheduled copa libertadores final second leg between boca juniors and river plate was postponed again after violence had forced the match between the bitter argentine rivals to first be delayed on saturday. the boca juniors team bus was attacked by river plate fans on its way to the game at river's estadio monumental and sunday's game was then postponed three hours before the new kick—off time. a decision on whether the match will be rearranged for another date has yet to be announced. marin cilic beat lucas pouille in straight sets to secure croatia's second—ever davis cup title. cilic beat pouille 7—6, 6—3, 6—3 to give them an unassailable 3—1 lead over hosts and defending champions france. france had pushed the final
