The british Prime MinisterBoris Johnson has less than 36 hours to sell the brexit deal he agreed in brussels on thursday to members of parliament in westminster. He needs at least 320 of them to approve it in a crucial commons vote on saturday. So is it possible . Heres our political correspondent, nick eardley. Many thought simply would not happen to borisjohnson many thought simply would not happen to Boris Johnson hand in hand many thought simply would not happen to borisjohnson hand in hand with Jean Claude Yorker sending of the brexit deal some thought was impossible. This is a great deal for oui impossible. This is a great deal for our country, the uk. I also believe it isa our country, the uk. I also believe it is a very good deal for our friends in the eu. And what it means is that we in the uk can come out of the eu as one united kingdom. Is that we in the uk can come out of the eu as one united kingdomm removes the controversial backstop and replaces it with new arrangements to avoid a hard border in ireland. Boris johnson arrangements to avoid a hard border in ireland. Borisjohnson still faces a massive cattle to get that deal through parliament. Moment he just cannot be sure it is a majority who will back him in the house of commons. The next 2a hours will involve some intense arm twisting, trying to persuade his own mps and some from the opposition to get on board. The Prime Minister runs a minority government here and, officially, every single Opposition Party is opposed to his plan. Crucially, the dup to keep the tories in power are not getting on board. In order to avoid trying to getan board. In order to avoid trying to get an extension he has been too eager by fire to get a deal at any cost. And the fact of the matter is had healed out and held his nerve he would have gotten better concessions. The pm will be back at his desk this morning to try and change minds, to convince everyone in his own party that the former tory mps and some labour mps who wa nt to tory mps and some labour mps who want to see brexit delivered. If he can do that, maybe, just maybe his deal could get through parliament tomorrow. But it is going to be tight. Joining me now is my colleague Nuala Mcgovern who is in brussels. A long day yesterday for everyone there. And, presumably, they are now watching, waiting and hoping that the deal gets through on saturday in the deal gets through on saturday in the uk parliament. Good morning from russells. Still quite early here as people diejust russells. Still quite early here as people die just what happened yesterday. Much of it took place earlier than what we were expecting. They said they had a deal and as you heard there from nick that left them with exactly what comes next, trying to get those votes for Boris Johnson. That was interesting. Yesterday evening there were a number of press conferences, one that took place with people who were intimately involved in the deal. Both leaders, Jean Claude Yorker and donald tusk and the irish leader all talking about this deal and what it took to get it done. They all expressed Great Sadness that the uk was leaving and mentioned that the door was always open if they can sit at returning that was followed by a press c0 nfe re nce at returning that was followed by a press conference with borisjohnson who took questions on some of those issues that nick raised in his report about whether it was a deal oi report about whether it was a deal or the report about whether it was a deal orthe dup, report about whether it was a deal or the dup, for the Unionist Party in Northern Ireland is that, quite clearly even yesterday morning, releasing a statement that they were not happy with the deal. That was reiterated up the deal was done. I think that is going to be Boris Johnsons biggest challenge, perhaps a stumbling block as it comes to trying to get the 320 votes in parliament on saturday special session whichjust to parliament on saturday special session which just to remind our viewers, nothing like this has taken place since the fall falkland walls in the 80s attic wars in the 1980s. They have ticked a box on brexit for this side on the continental mainland europe but what they will move onto with long term priorities in the budget for 2021 2025. The new leader coming in has not had some of her commissioners accepted. That has been a spanner in the work that she will present sessions today and many will watch that. Also, another aspect that has grabbed the attention of people all around the world will be climate change. Interesting to see how the eu set out their direct eaves for the coming year in advance of the Un Climate Conference taking place in december. This another busy day ahead. Another busy day ahead. A senior kurdish commander has said his forces will accept the 5 day suspension of fighting announced by turkey, but they will not be leaving. After the us Vice President flew to ankara for talks, turkeys president agreed to pause its military advance into syria to allow Kurdish Forces to retreat from a 20 mile zone on the syrian side of the border. Turkey began its offensive last week after mr trump said he would pull us forces from the border area. Rich preston reports. For days, turkey has been bombarding kurdish posts in Northern Syria with heavy artillery fire. Now, some respite from the bombing and gunfire. Americas Vice President and secretary of state arrived in ankara for talks after five hours of discussion with the turkish president , the deal was agreed. Turkey will pause its military operations for 120 hours to give kurdish fighters a chance to retreat. In a press conference, tu rkeys retreat. In a press conference, turkeys foreign minister insisted this is not a ceasefire, saying that could only happen between two legitimate sides. But a pause in fighting would become permanent only after Syrian Democratic forces com pletely left after Syrian Democratic forces completely left the area. Turkey wa nts completely left the area. Turkey wants the fighters to push away from the borders where it considers them a threat. But the ef, made up mainly of kurdish fighters, considers this its territory. It said it welcomes and enter the fighting would defend itself if attacked. 300,000 people, mostly civilians, have been displaced from the area and there are fears that this pause in hostilities will do nothing to help that. Well they want us to go . There is no place we can go. We are from here. These people have nowhere to go because this area is traditional kurdish area and the majority of people are kurds. Rot erdogan want, he wants the turkish cities. People are kurds. Rot erdogan want, he wants the turkish citiesm people are kurds. Rot erdogan want, he wants the turkish cities. It is not doable. President trumps withdrawal of us troops was condemned across the american political spectrum with many of them accusing him of abandoning us allies but mrtrump accusing him of abandoning us allies but mr trump has praised the amazing outcome saying will save millions of lives to their doubts over whether the agreement drawn up in ankara over the last 20 four hours is workable at all. Neither the kurdish leadership nor other key group such as syrian or russian governments we re as syrian or russian governments were involved in the talks. Lets return to brexit while Prime Minister borisjohnson is working out how he will sell his new brexit deal to Parliament Businesses are weighing up how it could affect future trade between britain and the eu if it gets approved for decades to come. Mrjohnson has written an open letter to businesses trying to reassure them. It says the deal is the basis for a new relationship with the eu based on free trade and friendly cooperation. Melanie eusebe, is a professor at Hult InternationalBusiness School and shes also the chair of black British Business awards. Shejoins me now. Do you think that what we saw yesterday and this deal that has been agreed finally gives business the certainty they have craved for so the certainty they have craved for so long . No, i dont think it gives us so long . No, i dont think it gives us the certainty. And that was reinforced some of from some of our Business Leaders yesterday. Most importantly it was reflected in the volatility of the pound. Throughout the day yesterday from moment the announcement was made and then the dup announcement as well, we saw how reflecting volatility we are not at a point of certainty. I think eve ryo ne a point of certainty. I think everyone understands that much is hinging on the boat tomorrow. Is it fairto hinging on the boat tomorrow. Is it fair to say that is holding back on decisions like investment in premises, taking on new staff and will continue to hold back until they have a bit more of a concrete idea about the future relationship between the uk and the certainly. We have been here before where a deal was taken and approved the eu and it comes back and is not approved by parliament. And so i think that most of the businesses will be holding back and saying all this look like on monday . And if there were to be any delay to the departure of the uk from the eu, what effect you think that would have on business . At this point there will be a delay because there is a two year period we must allow for. So i dont think it will change very much the reaction. We keep calm and carry on just as we did on monday. Perhaps with the stirling falling a little bit because we dont have that agreement that we desperately want very much. Come back later and we shall go through the papers together. The streets of the mexican city of culiacan have descended into violence after the son of notorious drug lord el chapo was arrested and then released by police. The detention of 0vidio guzman lopez led to a fierce street battle between masked gunmen and security forces. The countrys security minister says the decision to let him go was taken to protect lives. Lets go live to mexico city and speak to the bbcs will grant. What exactly does the security minister mean by that is to mark well, if you look at the images that are on social media taken by eyewitnesses of some of violence, it was extremely sustained and prolonged attacks going on by scores of government from the cartel against many police on the other side. Now the way that the local government, the State Government are explaining is that they took the decision to essentially release the son of el chapo for the protection of the town. But it is a murky picture and difficult to know. Is not wanted kingpin was briefly detained and in the and then he was back with the cartel. So an embarrassing moment, i would say, for the mexican government. In the circumstances in which he was found, what led to those . Well, again we are basing this largely on what was planned by the state security authority. They said that there was a routine role that was shot upon by members of the cartel in one house which, again, seems like strange but this is their version of events. 0nce seems like strange but this is their version of events. Once they got it under control they are dead one of them as being the leader of the cartel and when this huge reaction from the cartel members. What i would say is that the images show real panic on the streets. This was taking place in the Main Business district, in the Main Commercial district, in the Main Commercial district and some images show people running from shopping malls and restau ra nts. Running from shopping malls and restaurants. And the noise of the gunfire is harrowing. So we still dont know exactly how many people died or were injured in this attack. Thank you very much.

Hey, peter bowes, has the details. Guys could this bet gun . An apparent admission from one of the most seniorfigures in an apparent admission from one of the most senior figures in the white house that military aid was being withheld from the ukraine in return for a politically motivated investigation. A quid pro quo. Mike mulvey new surprise reporters when he said funds were held back to put pressure on ukraine over an investigation into the hacked server belonging to the Democratic National committee. I was involved with the process by which the money was held up temporarily, 0k . Three issues for that. The corruption in the country, whether or not other countries where participating in support of the ukraine and whether or not they were cooperating in an Ongoing Investigation with the department of justice. To be clear you, you just described a quid pro quo, funding will not flow unless there is an investigation into the democratic server . We do that all the time with foreign policy. Democrats, who launched an impeachment investigation into the president , have seized on mr mueller they needs words as evidence mr trump had been acting inappropriately. The idea that vital military assistance would be withheld for such a patiently political reason, for the reason of serving the president s re election campaign, is a phenomenal breach of the president s duty to defend our national security.

Im ben croucher with your friday sports briefing. Well start with golf, and its the european tours french open, scene of where europe and the usa battled out at the ryder cup last year, but its a new zealander and a South African with the first round lead at Le Golf National in paris. Ryan fox and this man, george coetzee, are a shot clear of the field on six under on a day where 49 players went under par. Coetzee made a birdie on his first hole and followed it with six more.

Alexander rublev is one of two russians through to the quarter final at the kremlin cup tennis in moscow. He beat Egor Gerasimov in three sets to join defending champion karen kachinov in the last eight. In the womens draw, there was a surprise as top seed Elina Svitolina was dumped out by veronika kudermetova. It was the biggest win of kudermetovas career, playing against a top five player for the first time. From moscow to antwerp, where andy murray is in quarter final action at the european open on friday. Its after another win, this time over eighth seed pablo cuevas.

Getting there is hard enough, but what do you do once you arrive . Well, nasa has been looking at some possible, albeit unusual, living arrangements, as the bbcs tim allman reports. At first glance, this looks a bit like a big bouncy castle thats fallen over. But it might, just might, be the solution to living among the stars. Its called expandable architecture, an inflatable habitat that could be used for a possible orbiting lunar space station or as a potential home for astronauts staying on the surface of the moon or even mars. And the whole point is to define what we like and dont like about these different habitats. And, from that, we will aggregate all the data and come up with recommendations and even requirements for what we actually want to go to flight with. Neil armstrong thats one small step for man, one giant leap for mankind. When Neil Armstrong and buzz aldrin first set foot on the moon 50 years ago, it was only the briefest of visits. They were there a matter of hours, rather than days, weeks or months. And they travelled in cramped conditions, effectively in a small metal box. Neil armstrong thank you, mr president. This is the sort of Living Environment modern astronauts could expect. Its not exactly spacious, but its positively roomy compared with what came before. Potentially, we think that for the rest of this century this, the expandable architectures, is where it is out, not in the aluminium cans. This is a mock up of what a potential lunar space station might look at like. Construction is due to begin some time in the next decade. Another giant leap could be just around the corner. Tim allman, bbc news. Hour talking point today is based on this article on the bbc news website, a study that has found actually banning out of hours e mail for staff to try to give them some downtime and reduce stress could actually do more harm than good if it stops them achieving work goals. It can actually cause more stress. I was asking for your tweets on this, do you check work e mails from home . Do you check them on days off and how do you deal with inbox overload . Gareth says, i regularly check, deal with and answer e mails outside work time and its the only way to deal with workload stop peter got in touch and said luckily myjob doesnt involve getting work e mails but i think there needs to be a clear divide twin home and work life. Charles says, i check my e mails out of work, i like my phone on 2a 7. Do you . I think the answer is right there, isnt it . Keep them coming in, make sure you use the hashtag and we will go through more of them later. Coming up, the news briefing. Dont go away. I dont doubt many of you have seen scenes like that over the past few days. Longer spells of rain, some pretty hefty showers around, that was certainly the way of it through thursday across many parts of the British Isles and i dont think were going to a great deal of change going through friday because the big area of low pressure is very much the dominant feature and it could be really quite a wet start across the transpennine england, some of the eastern counties will have seen a lot of rain overnight so a lot of surface water. Showers from the word go in the west but once the rain has cleared from the east, but not the north east, there could be rain lal in proceedings with brightness breaking out but dont be full because some showers in the west and south will go north and east. Parts of scotland will be drier away from the south eastern borders, Northern Ireland will have a mixture of sunny spells and showers. Into saturday, not a great deal changes. The low pressure still there, a banner of cloud associated with a weather front in the north east of scotland, on into the north of england and central belt through the morning and into the afternoon. Elsewhere, quite a bit of dry weather around but if you catch a shower it will probably be sharp and things turning cool in the north and things turning cool in the north and west of scotland and Northern Ireland, for the exposed to a strong, north easterly wind and you can see the isobars im putting onto the chart. 0n can see the isobars im putting onto the chart. On sunday, apart from that old legacy frontjust hanging on in there to give you a fair amount of cloud, drab conditions in eastern scotland and the north of england, to the north and south of it, though, theres the chance of drier conditions, fewer showers to speak of, a couple in the mix but a com pletely speak of, a couple in the mix but a completely different kettle of fish to recent days. Thats how we move into the start of next week. At least on monday and tuesday, a lot of dry weather around and a bit of mist and fog around. The winds dropping out in your neck of the woods . That could lead you into a bit of frost, mist and fog to start monday, but there will be a lot of dry weather because we got rid of that area of low pressure and its attendant fronts. The High Pressure is toppling in. Once the day gets going, sunshine and a lot of dry weather around. Temperatures down a degree or two. Tuesday, not a great deal of distance no difference, still the High Pressure holding on across the greater part of the country but turning wet and windy by midweek deal of difference. This is the business briefing. Im ben bland. Free trade and friendly cooperation. Borisjohnson promises business a Bright Future after brexit. But he could face years of negotiation over eu rules and market access. Plus the trade war takes its toll. Chinas growth slows to its weakest in more than a quarter of a century. And on the markets sterling fell as investors fret over Boris Johnsons chances of pushing his brexit deal through parliament, while asian markets were mostly down after that data from china
