this is bbc world news today. i'm aaron safir. our top stories. european union leaders have endorsed the terms of a brexit deal — after 18 months of negotiation. theresa may says her deal delivers for the uk — and this was her message to potential rebels at westminster. the british people don't want to spend any more time arguing about brexit. an investigation by media organisations around the world has revealed that unsafe medical devices are being implanted into patients. and... just hours to go until nasa's latest probe is due to touch down on mars. getting there's the easy bit — it's the landing that's tough. hello and welcome to world news today. the british prime minister theresa may can now breathe a sigh of relief — after eu leaders in brussels gave the official nod

of approval to her brexit deal. it is a significant milestone — but there are still details which need straightening out — and the focus now shifts from brussels to westminster where the deal must be ratified by the british parliament. we start our coverage with this report from the bbc‘s political editor laura kuenssberg. no celebration, no fanfare, but a huge and serious step. after more than a0 years inside... deep breath — the deal to leave is done. 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. in any negotiation, you do not get everything you want. you need to identify what your vital interests are and stick to them but be prepared to compromise in other areas, in order to achieve a result. i think the british people understand that.

her bet — many of you are bored of the rows, the splits and the spats. the officials who brokered the compromise watching on. before christmas, mps will vote on this deal. on it will depend whether we move forward together into a brighter future, or open the door to yet more division and uncertainty. the british people don't want to spend any more time arguing about brexit. can i ask you to be very straight with the public and tell us who, if anyone, you think is pleased about this deal? what we see in this deal today is a deal that delivers for people, delivers on the vote, delivers in a way that protects jobs and livelihoods, and protects our security and our united kingdom. and, as i have said before, i believe our best days lie ahead of us. the eu's power players have agreed a brexit with caveats. a deal where the uk leaves next march but stays close to the union, with a lot of final

detail yet to be agreed. ahead of us is the difficult process of ratification, as well as further negotiations. but, regardless of how it will all end, one thing is certain, we will remain friends until the end of days. and one day longer. it is time for everybody, everybody, to take their responsibilities. today's agreement will help create the trust and the confidence needed for negotiating our close and unprecedented future relationship. the agreement was hard—fought on both sides, even though sometimes it feels like eu leaders still can't quite believe what's happening in front of their eyes. it's tragic that the uk is leaving after 45 years, angela merkel said.

but there may be more theatre to come. mps at home might kick out the deal. would they budge here, then? this is the deal, the best deal possible and the european union will not change its fundamental position when it comes to this issue. are you concerned that the prime minister may not get this deal through the british parliament? i think it is not now our concern. it is the british concern. this is the best we can do. both theresa may and her government and us in the european union, there are no victors here today. nobody winning. we are all losing. they have been many moments when it has not being clear that theresa may would make it this far. but her next steps, these vital few weeks, will determine her future and the future of the country. for the prime minister there is now only one direction, she cannot know if parliament

and the public will follow along. joining us live from brussels with the latest update, is the bbc‘s gavin lee. a choreographed day and one that achieved what was on the agenda but one thing not discussed is what happens if the deal does not get through the british parliament. happens if the deal does not get through the british parliamentm isa through the british parliamentm is a good point because in one sense you could copy and paste the comments, remarks from the leaders of the doorstepping reporters today on the irish prime ministers said that they had agreed by consensus not to talk about the what ifs. just in case they end up doing something that inadvertently could affect the vote goes they first of all do not wa nt to vote goes they first of all do not want to see this withdrawal

agreement reopened again or we negotiated. only one leader seem to have stepped out of line today, the president of lithuania who said it things did not go to plan in the british parliament then either there would be no deal or they would have to re—negotiate. so i think the other leaders have been told to step back. the feeling if theresa may came knocking, perhaps they would at first pretend they were not in. because they do not want to have that question again, they believed this was the important bit today and they are all aware how it is going to be difficult in the days to come on this side of the water. december the 10th is the likely date for that british parliament vote. and theresa may now selling the steel to the british public, is that something that the leaders in the eu deal, that the leaders in the eu deal, that they've made concessions to the uk? well the language that they

used, i think there are still areas we re used, i think there are still areas were other countries are not happy, the dutch, the belgians, the portuguese and french all talking about wanting reciprocal rights to fishing. the french resident saying today if talks to words a trade deal start to get tough the leverage point would be the fishing issue. he had the spanish onlyjust agreeing to the future terms of for the these things could reopen again but for 110w things could reopen again but for now the leaders are unanimous saying we had done all we can at this end and let's see if it goes through, they hope, the british parliament. thank you. and of course plenty more on that throughout the programme. let's take a look at some of the other stories making the news... there's been a sharp escalation in a naval dispute near crimea. the ukrainian navy says a russian coastguard vessel has fired on one of its gunboats in the waters between russia and crimea — the ukrainian territory annexed by russia four years ago. it said russian special forces had seized the gunboat and two other ukrainian naval vessels. ukraine also accused the russians of shooting to kill. there's been no

confirmation from moscow. the main border crossing between mexico and the united states has been closed in both directions after migrants broke through a security perimeter in the city of tijuana. tensions have been high in tijuana since the arrival of thousands of migrants earlier this month. president trump has deployed thousands of troops along the united states' southern border to stop the caravan, which he says is illegal and politically—motivated. the deadliest wildfire in california's history has now been fully contained. the blaze, known as the camp fire, started over two weeks ago, north of san francisco. firefighters were able to extinguish the flames following several days of rain. the fire killed at least 85 people and destroyed thousands of buildings. almost 250 people are still unaccounted for. an investigation has revealed that medical devices that are unsafe and have not been adequately tested are ending up inside patients' bodies. bbc‘s panorama programme, together with the international consortium

of investigativejournalists, investigated how potentially dangerous products get approved. the industry says it has transformed millions of lives for the better. deborah cohen reports. medical devices can transform our health. they keep us walking, seeing, and our hearts beating. there are thousands of companies trying to sell the latest gadgets. what they won't necessarily tell you is that new does not always mean safer or better, or that some devices might actually damage your health. here we go, that is where you put it. maureen mccleeve was the first person in the uk to be fitted with a new type of pacemaker that sits inside the heart. but the battery died after just three years, and doctors could not get it out. i don't like the thought that i've got a piece of metal in my heart that is doing nothing, and it's just laying there. the pacemaker was withdrawn for safety reasons.

at least two deaths and 90 events in which patients were seriously harmed by the device were recorded. our investigation also found an implant that was approved for humans, despite failing in a study on baboons. and a treatment for children with curved spines that was only tested on pigs and dead bodies before being approved for use in the uk. critics say medical devices should be tested more thoroughly, and the results of studies should be made public. as a patient, i would be terrified not to know the the adverse effects. but you have to have data in order to know if something is safe or dangerous. we are talking about people's lives, it is really important to know whether these devices are safe or not. the european union has legislated to make the industry more transparent, but panorama understands the crucial information

about medical devices will not be shared because it might scare the public. it's not about scaring patients. there are risks. that's the issue, you have to inform people even if it is one in a million, you have to tell people. that is immoral, unethical, and illegal, in my mind. the manufacturers say their products were tested thoroughly and met all regulatory requirements. the industry insists there are already proper checks in place to protect patients. deborah cohen, bbc news. stay with us on bbc world news. still to come: the final of the copa libertadores has been postponed again, after a bus carrying one of the teams was attacked by rival fans. what does this mean for the region's biggest match? this is bbc world news today. the latest headlines... european union leaders have endorsed the terms of a brexit deal — after 18 months

of negotiations. theresa may says the deal delivers for britain, and she urges people from all sides to unite in the national interest. staying with that story and how the british prime minister now has to convince mps from all parties to support her deal. i spoke to rory stewart, who is the uk'sjustice minister and a supporter of the deal. i asked him what kind of a day it was for the prime minister. i think we should acknowledge that for europeans, for many europeans anyway, europe is a very precious thing particularly because they associate it with peace after the second world war. and britain is a very major economy, the second largest economy in europe. so i think it is a difficult day for europe. but i think this could be the beginning of a positive new relationship. you may think so, lots of people back in the uk don't. what chance does theresa may have of selling this deal to the british public?

it depends whether we can explain the deal and also depends whether we can explain clearly that there are essentially only three choices here. you can either try to remain in the european union, which is effectively to deny that the referendum happened. or you can go for a hard brexit, or you end up talking about this deal. in a letter she released to the british people she talked about renewal and reconciliation, she talked about getting rid of the labels leave and remain once the uk leads the european union. that is something you have been quite concerned about. whatever happens at the end of this process, is it going to be possible for the british people to reconcile these quite strongly held, opposed views? the question is, and you are right, there are these strongly held views and of course on social media for example i'm being attacked almost equally from people who want to remain in the european union and people who want a no—deal brexit. the question is how many of those people are there.

and i guess that is what we are discovering. there are clearly some people in britain who violently either don't want any change at all or a very radical break. of course i believe and i think the prime minister believes that the majority of people are pragmatic, they recognise the referendum happened, they recognise something different needs to happen. they recognise it should happen quickly. and they want to move on with the minimum economic disruption. surely there will be a lot easier to sell this to the british public if you knew exactly what was in this package that you are offering them. the withdrawal agreement is quite detailed. the political agreement outlining the future relationship is a lot shorter, a lot more vague. can you give the british people are guaranteed that you can tell them exactly what it is they will be getting if they back theresa may? the political agreement is a heads of terms,

it lays out the basic headlines of what will be negotiated over the next couple of years. this is an ongoing negotiation, but as the beginning i think it is very reassuring. people who said that europe would try to punish us, this would be humiliation for britain, that is not the language of that deal. and europe is also, one of its strengths is it is an extremely legally bound organisation and therefore when it puts something in black—and—white that is likely to have quite a lot of impact on the way that negotiations go. the british justice minister rory stewart there backing theresa may's deal. but will the prime minister be able to convince british voters? the bbc‘s olivia richwald has spent the day in skipton, in the north of england finding out what some voters think. skipton in the yorkshire dales is a prosperous market town, attracts plenty of tourists, and votes tory blue. but in the red lion pub, it was time a sunday at lunch and a chew over the brexit deal. it might be pleasing both sides, and that's what she is trying to do. she's tried to please everybody, and it will not be a good deal for either side.

it looks unacceptable, and if enough brexiteers have left the cabinet because it's so bad, then theresa may and all her remain colleagues are just pushing it through, it looks awful. in the referendum, 53% of people here voted to leave the eu, similar to the national result. among them, zoe venn, who has lived in the town all her life and helps to run the family canal business. i think it isjust dragging on a bit now, i think they could just do with getting the deal done, and then, we can move forward. in the town centre, the local band is on stage. the majority of them voted to remain, but we took two members with opposing views aside. i think it's a piece of paper that has something on it, i cannot see this deal ever happening. i don't think this country

will leave the eu on those terms. i'm not sure we could leave the eu. but i don't place a great deal of stock in this. it was presented as being a simple job, a simple negotiation. and actually, it has been incredibly complicated, we've been tied in to so many aspects of the eu. do you think that me and you, that we will get a square deal out of any of this? i think the only thing we can hope is that the country becomes more prosperous in the future, but it doesn't look like it will happen for a long time. despite their differences of opinion, the band played on. whether the same could be said for those in power is anyone's guess. olivia richwald, bbc news, skipton. mars has many mysteries — and one nasa hopes to solve

in its latest mission — is what lies beneath the surface. the mars insight lander — which runs on solar power — is due to touch down on monday night. but landing on the red planet is far from simple. most missions fail in the final moments. to be successful — the spacecraft must enter at exactly the right angle. if everything does go to plan — the mars insight will study and monitor deep within the planet until 2020. i've been speaking to our science correspondent victoria gill — she's in pasadena california — mission control for the insight lander. a very risky operation indeed, yes. only 40% of attempts to land on the red planet have been successful. you can probably hear the hubbub around me because there is a real sense of anticipation growing here. scientists are arriving from all over the world because this is truly an international mission. the scientific kit aboard this lander, there is actually a life—size model of that behind me. it is a 3—part experiment contributed to by scientists and engineers from all over the world. and the world's media is arriving because tomorrow evening

here there will be an attempt to land on the surface of the red planet near the equator. but that attempt, as the first entry points, from the first entry point to it actually touching down on the surface, is commonly is commonly known in nasa terms as the seven minutes of terror. because in that seven minutes this lander will have to actually slow down from six times the speed of a high velocity bullet to a safe touchdown speed, plant its three legs on the ground, and only then when it is sitting safely, can it start to do that two year—long or possibly longer science mission. drilling down into mars, studying its deep interior for the first time. ok victoria, and briefly if you can, this probe is looking to study the interior of mars. what will that tell us, why do we need to know this? there is so much more we can learn by looking beyond its surface which is all that scientists have been able to do with missions so far. so understanding the structure of mars will tell us

exactly what it is made of. so listening for mars quakes and also understanding what those waves of sound are travelling through, to understand what mars is actually made of deep inside. that will tell us exactly why when mars and earth are made of the same stuff, they have evolved into very different worlds. and why earth is so special that has allowed it to become so habitable. holly hamilton has the sport. hello, and thanks for joining us on sport today. we start with what's been described as a huge embarrassment for south american football. the final of the copa libertadores has had to be postponed yet again. the second leg between argentinian rivals river plate and boca juniors had already been suspended after the boca bus was attacked on its way to the game on saturday. a number of players were injured by glass and tear gas which caused the game to be delayed by 2a hours. well, earlier, organisers decided the game could not be played in buenos aires today... this match was in doubt ever since

the first rock was thrown at the bus on saturday. the one consistent factor was boca's adamant refusal to play the match despite heavy pressure from the south american football authorities. boca said conditions were not equal for both sides and their captain is still recovering after sustaining flying glass to his eye. then the head of south american football agreed with that decision and a new date is expected to be announced soon for the match. in the english premier league arsenal extended their unbeaten run in all competitions to 17 games with a victory at bournemouth. arsenal took the lead through a first half own goal but bournemouth equalised with a brilliant strike from joshua king. pierre emerick aubameyang scored the winner with 25 minutes to go. arsenal remain fifth

in the premier league but are only three points behind spurs ahead of next sunday's north london derby. in sunday's other premier league match huddersfield started the day bottom of the table but a 2—0 victory at wolves, which sees them move out of the relegation zone to 14th. two goals from aaron mooy helped them to a deserved victory. in spain, sevilla went to the top of la liga — one point ahead of barcelona — after a narrow win over real valladolid — portuguese forward andre silva with the only goal there. elsewhere, girona beat espanyol while atletico bilbao had to settle for a draw with getafe. in the late kick off, villa real are currently leading betis 2—0. in italy, second—placed napoli dropped two valuable points in their serie a title chase when they were held to a 0—0 draw at home by chievo. elsewhere, empoli come from 2—0 down to beat atalanta 3—2. and lazio snatched a 1—1 draw against ac milan.

croatia have beaten holders france to win their second davis cup title. holding a 2—1 lead heading into sunday's singles rubbers, marin cilic had the chance to give croatia the trophy and his straight—sets win over lucas pouille was enough. this is the final staging of the team competition in its current format before it changes next year. croatia last won the competition in 2005. lewis hamilton rounded off another title—winning year with his 11th formula 1 victory of the season in abu dhabi. it marked the end of the campaign, and the f1 career of fernando alonso, who could only finish 11th — failing to win a point in his final race. red bull's max verstappen and daniel ricciardo took third and fourth on the podium, while hamilton took his place on top — in unusual attire...

or lack thereof. australia beat england by eight wickets in the final of the women's world t20 in antigua. england, who are reigning one—day champions, were bowled out for 105. danni wyatt top—scoring with 43 and australia chased that down fro —— for the loss ofjust two wickets with almost five overs to spare. it's australia's fourth t20 world title. that's all the sport for now. and that is all from us. thank you for watching bbc world news. a complete change on the way in the

coming days. atlantic weather systems start to not on the door from tuesday. monday is still looking fine. over the next few hours we have the wind dragging in some cloud from the east. temperatures by early on monday above freezing in the city centres but outside of town there will be some frost. then tomorrow very much an east west split. a lot of thick cloud to the east of the country. whereas in the west we have sunshine. then tuesday morning onwards those weather fronts. to line up in the atlantic and head are away. on top of that we have an increasing wind as well. by the afternoon central parts of the uk affected by that heavy rain.

northern areas will stay dry for most of the day. by the middle of the week we have low pressure in charge. dominating the whole of the north atlantic. with that comes much milder weather reaches all parts of the country by wednesday. lots of showers, a gale force wind inland and severe gales around some western coasts. these are the average wind speeds and in some cases they could even triple. 1a in london, 11 degrees in the north so double figures due out the country. on thursday low pressure caused by sending ina thursday low pressure caused by sending in a strong wind and frequent showers. in between those showers you get the sunshine as well. that is unless you're stuck underneath a weather front across southern areas. not all bad however,

not winning all the time. 1a degrees in london but not feeling like that if you're in the wind and the showers. then low—pressure moving in across the country on friday bringing some wind as well. goodbye. this is bbc world news — the headlines: a european union summit in brussels has backed the brexit deal. calling it a sad day, the president of the european commission, jean—claude juncker, said that it was the best and only agreement possible. it needs to be approved by the uk parliament, with many mps opposed. theresa may has insisted that the deal is the best way of implementing the referendum decision. the american space agency says its latest mars probe — insight — is on track to touch down on the red planet on monday. only a third of previous international missions have succeeded. one of the biggest football matches in argentina's history — the copa libertadores final — has been postponed again after the boca juniors team bus was attacked by rival fans in buenos aires.
