Bring together the best of the international journalism, bring together the best of the internationaljournalism, and bring together the best of the international journalism, and the biggest global stories. Two big interviews to bring you. The first is with a former colleague of Harvey Weinstein. She sat down with Emily Maitlis and gave details of what it was like to work with the former hollywood producer. The second is with President Trumpss National Security advisor, hr mcmaster. About north korea, alleged russian interference and the election. Lets begin with Harvey Weinstein, because a former colleague of his has told the bbc she was warned about about his behaviour and tried to warn other women he could behave in an inappropriate manner. It seems so recent, given how much has happened, but it was only back in october that the New York Times detailed many allegations of Sexual Harassment against Harvey Weinstein. And the allegations have kept coming. Among his accusers are the actresses rose mcgowan and ashleyjudd. To date, 80 women have come forward with allegations. This has become a much broader story, the metoo campaign. More than 100 powerful and influential men across a range of industries faced claims of Sexual Harassment. Including big hollywood stars like kevin spacey and dustin hoffman. Well, this is Zelda Perkins story. She was a colleague of Harvey Weinstein and has spoken to Emily Maitlis. It came to a head when he sexually assaulted, attempted rape on your colleague . Yes, we were at the Venice Film Festival and he tried to rape her. What did you do . What because he knew why i was angry. And so serious. So you accused him of attempted rape . Yes. He denied it . Yes. He said nothing at all had happened and he swore on the life of his wife and children, which was his get out ofjail card. He used that quite a lot. Heres the bbcs entertainment correspondent Colin Paterson with more on this story. Women . . . 15; the women, saidthiswas neba ancl , only if agreement. To the 77 77a therapy ri f, to. At miramax and therapy for Harvey Weinstein. This was not known if these stipulations were carried out. Zelda perkins signed a nondisclosure agreement and received £125,000 in payments. In interview, she calls for britain to follow the example of a number us states and end the practice of allowing sexual assaults to be hidden behind nondisclosure agreements. A spokesperson for Harvey Weinstein says he unequivocally denies any allegations of nonconsensual six. More details of that story on the bbc website. Donald trump is on the brink of his first major legislative victory. In the last hour, what is being described as the biggest overhaul of the us tax system in 30 years was voted through the house of representatives. Heres Speaker Paul Ryan making that announcement. Pdas are 227 and the nays 203. It is adopted and the motion to consider is laid upon the table. Speaker ryan looking pleased about that development. The next test is the senate. It will be a close vote, but it looks like it could go the way of the republicans, partly because of a decision made late on monday by these two senators, Susan Collins and mike leigh, who had been holding off from saying they would support it but have in line. The republicans are looking happy, needless to say, the democrats are not. They are concerned about an estimated 1. 1; trillion that could be added to americas deficit. And it is the principles behind this, the democrats criticising bernie sanders. 0n the democrats criticising bernie sanders. On twitter, he says this. Rajini Vaidya Nathan is in washington. How is it the democrats can say it will not help working families, the republicans say it will . Can we not look at the legislation and work this out . If you look at the way the house of representatives voted, it certainly is very much divided down party lines and not a similar single democrat voted for this tax reform, although 12 republicans did vote the other way, but they still we re vote the other way, but they still were able to pass the bill. In a nswer to were able to pass the bill. In answer to your question, this is very much ideological eat a divided issue. You have republicans who believe cutting taxes, one of the landmark things in this bill, is to reduce Corporation Tax to 21 . Republicans believe by reducing cuts like this, it will stimulate growth in the economy, increase jobs and boost gdp. Republicans have that view and on the other side, democrats look at this tax plan and they see it is poorer americans who will not be making the most games. Rich and wealthy americans are the ones, according to independent analysis, who will make the most in this plan. And there are concerns tax cuts come at a cost. Democrats concerned entitlement and welfare programmes could in the next year be cut in order to pay for this. And aside from the finances, the politics of this are fantastic for donald trump, a great way to finish the year. Yes, he has described this asa the year. Yes, he has described this as a Christmas Gift for the American People. And you could say it is a Christmas Gift for him and for the republican party. This is his first major legislative victory. I spent a long time during the Election Campaign travelling across the United States and two big things people said they wanted changed were repealing and replacing 0bamacare and also reducing taxes. But one thing voters would say, will congress ever be able to get anything done . We have not seen bipartisan agreement on this, but republicans have rallied behind this tax plan eventually and this will be seen tax plan eventually and this will be seen as a tax plan eventually and this will be seen as a huge victory for donald trump and something he can say to his base as he completes nearly his first year in office. Thank you very much indeed. And we will go back to the states to look at what this new tax legislation will mean for americas biggest companies. Staying in the us. President trumps National Security advisor, hr mcmaster, has been speaking to the bbc. It was a wide ranging interview he talked about north korea, alleged russian interference in the us election and his boss, donald trump. Yalda hakim was asking the questions. Well hearfrom her in a moment. First, heres hr mcmaster on north korea. You committed to a peaceful resolution to this. Of course, that is what we want, but we are not committed, we are committed to a resolution. We want the resolution to be peaceful, but as the president has said, all options are on the table and we have to be prepared if necessary to compel the denuclearisation of north korea, without the cooperation of that regime. Yalda gave us her thoughts on the interview with hr mcmaster. It is difficult to work out exactly what they intend to do and when i pushed on whether war was imminent, hr mcmaster did not go as far as saying it was, but he said, all options are on the table. What they are trying to do, from what i gathered from the conversation with hr mcmaster, they want to make sure that they maintain the pressure on north korea, and that is why they say talks are not something that they want to entertain at this point. But they must ensure that countries like china, russia and themselves, the United States, maintain the pressure on north korea, to ensure that they do not obtain any weapons. He said it was absolutely intolerable for the United States and for north korea to have weapons, to use against any of the countries in the region and, indeed, the world. On that issue of talks, stay with us please. You got in the us policy on whether to talk directly to north korea and you could be forgiven for being confused. Is tuesday, secretary of state Rex Tillerson said this, grow within 2a hours of saying that, but the white house and the state department was saying, north korea has to abandon its Nuclear Weapons 01 has to abandon its Nuclear Weapons or commit to do that before any talks. What the president has said and the senate of state, if ijust last week, now is not the time to talk. What we have to do is see a fundamental change in behaviour. A fundamental change in behaviour. A fundamental shift in conditions. Because we cannot afford any more, because of how far down the road they are in these capabilities, to repeat the mistakes of the past. Would you be willing to talk to the north koreans and talk across the table bilaterally . Under what conditions, is a question . If there was no agenda, just talk. That is really going to be up to the president to decide. What is clear now is that we cannot in any way rele nt now is that we cannot in any way relent on the effort to continue the isolation, the regime, diplomatically and economically. To what extent it is you feel hr mcmaster was speaking on behalf of mrtrump orjust mcmaster was speaking on behalf of mr trump or just someone mcmaster was speaking on behalf of mr trump orjust someone separate but an adviser to the president . M seems they want to present a united front after that confusion that the secretary of state created last week when he said the door was open. He said they would talk to the north koreans and sit across the table, that there were no preconditions or agenda and they could talk about the weather if they wanted, but at least talk. So he wanted to clarify that. Isaid talk. So he wanted to clarify that. I said there was confusion and can he understand the mixed message from the white house . He wanted to present a united front, that the white house has one message, the denuclearisation north korea. And now is not the time for talks. The door might open at some point, and that was not the case at this point in time. One other thing from your interview is to do with russia. Not releva nt just interview is to do with russia. Not relevant just because of interview is to do with russia. Not relevantjust because of those alleged interferences in the us election, but there is a greater global struggle. America must donald trump admitted such yesterday, he said. This is what hr mcmaster said about russia. What we endeavour to do with russia, three things. Of course we have the counter russias destabilising behaviour and the sophisticated campaigns are propaganda and disinformation. Effo rts propaganda and disinformation. Efforts to polarise communities and pit them against each other, especially in the democratic world and ina especially in the democratic world and in a free and open society, and we also need to prevent war with russia and so we need a more holistic view of deterring conflict with russia. And find areas of cooperation. And do you believe russia medalled in the 2016 elections . I believe that russia has engaged in a very sophisticated campaigns version to affect our confidence in democratic institutions, in democratic processes. Institutions, in democratic processes. Including. Including your elections . What they used as propaganda and disinformation, on both sides. He did not want to a nswer both sides. He did not want to answer that question, did he . No, as you can imagine, this is something that has been the focus of so much in the United States. And globally. Whether President Trump will acknowledge whether russia interfered in the 2016 elections. And so hr mcmaster was really quite relu cta nt to and so hr mcmaster was really quite reluctant to go as far as saying that russia had interfered. But in the end, he said the president had acknowledged publicly and he acknowledges it and he acknowledges what the us community has said for well over a year now, that the russians had been involved in some form of interference. But he went back and reiterated that really it was cyber tools the russians are using to challenge the democracy is not just using to challenge the democracy is notjust in using to challenge the democracy is not just in russia, using to challenge the democracy is notjust in russia, but other places like mexico and catalonia, he pointed out as well. But i really had to pushing to get an answer on that. He is hugely influential, what impression did you leave of what this man wants to create . The sense that i got is that he is known to be a soldier and scholar, he is a strategist who thinks long term. When i asked him if his life would be easier if donald trump stopped treating you said i can only control what i can control. He said his focus was on the National Security of the American People and to present all the options for the president weather on russia, china 01 president weather on russia, china or north korea. You really want to serve his country. Thats the sense i got. If youd like to see a full interview it will play out on friday. You will also find it online as well. In a few minutes we will go to the west coast on the latest investigation into that train derailment. It was going almost three times as fast as it should have been. A man has been sentenced to 20 years in prison for throwing acid into the crowd at a packed nightclub. Arthur collins, the former boyfriend of a reality tv star, was seen squirting the liquid into a group. The commander of Hackney Police says the sentence is appropriate. Its a very clear message that anyone who carries or uses acid will go to prison for a long period of time. The trauma and psychological distress of those people is huge. This was a predetermined attack. He knew exactly what he was taking into that they club. For whatever reasons he used it three times. His intended victims were burned with acid but lots of innocent people were there and he did not care about what he did. Were live in the bbc newsroom. Donald trumps National Security adviser has been speaking to the bbc about the threat posed by north korea and russias meddling in the us election. First of all, at least 11 people have been killed in mexico when a bus carrying Foreign Tourists crashed. The bus was travelling to the eastern tip of the peninsular when it veered off the road. The nationalities of the dead have not been established. A mass grave has been established. A mass grave has been identified. 650,000 muslims have fled an offensive by the military. Lets talk about that train which derailed in the us. It was doing almost three times the speed limit. Heres a statement we heard from the authorities. The information we have, the investigator in charge has obtained the download of the data recorder. Preliminary investigations are that it was travelling at 80 mph in a 30 mph track. This train was travelling at 130 kilometres when it was supposed to be doing 50. The derailment happened so far seattle. Three people died and 70 were injured. It was heading towards portland but it never reached its destination. It left the tracks on a bridge over the interstate high five. This is one picture we have of the scene. You can see this arrow. This is the front of the train, a long way from the tracks. You can see the devastation between the front and the back of the train. Let me show you some of the latest pictures to come into the scene. You can see some very heavy lifting as the carriages dangling from the bridge are being moved and placed on particularly large lorries which have the facility to take these carriages away. Lets speak to james cook, who is following this story from los angeles. Some people might be surprised to hear that a train can be driven at three times the speed limit without some system or another kicking in. Yes, that has been a matter of some controversy for several years. The technology to prevent a train from exceeding the speed limit or at least reduce the speed limit or at least reduce the speed has been available for many yea rs speed has been available for many years and safety campaigners have been agitating for it to be introduced for a long time. Theyve had some success, in that it is now legal that it must be introduced but not until 2018. The campaigners said if it had been introduced on this track and train it would have saved these lives, possibly. In terms of these lives, possibly. In terms of the situation that played out on the road below, do we know how many were in the car is and how many were in the trains . We dont have a final breakdown of those numbers but we know that there were several injuries on the motorway. As we see from the picture you were pointing out, the train has gone essentially straight on that curve. It has crashed over that bridge, landed on the motorway and hit seven vehicles including a lorry that was on the road and several cars and trucks. Nobody on the motorway was killed. There were injuries but the three deaths all occurred on the train itself. In a sense it could been a lot worse but clearly there are no a lot worse but clearly there are no a lot of about this new routes, was the driver unfamiliar with the route . Was he distracted . Clearly there is a debate about whether ra i lwa ys there is a debate about whether railways in the us are up to scratch. This is the latest in a string of accidents. The focus is on the behaviour of the driver at this stage. President trump tweeted this was evidence of underinvestment in the infrastructure of america. Is there any evidence that that played a role . Its complex. The president has a point in the sense that if this technology had been available it could have prevented this crash but the point he tweeted, nobody really knew for certain what had happened. Is this a case of a crumbling track with an old train . It doesnt seem to be the case. This was a new stretch of track. It was a stretch that had been upgraded to carry this train on its inaugural run. It was designed to shave ten minutes of the journey time from seattle to portland. Some have criticised the president for jumping to conclusions. We will stay in the us but come back to the east coast. It looks like the biggest tax overhaul in 30 years is going to go through. Its been approved by the house of representatives. The senate looks likely to approve it. One of the Biggest Challenges it will take is Corporation Tax. It will bring it down to 21 from 35 . That is seen as being a good thing if youre a republican, kick starts businesses, a bad thing if youre a democrat, worried about the deficit. The hope is some of that money will come back on shore. Is that right . Yes. The big hope is the savings the company will make full be reinvested here and create more jobs. Will make full be reinvested here and create morejobs. Another part of the bill is when us Companies Move profits overseas, what is currently happening, they are taxed in the us as well. Now they will not be taxed for profits made overseas. Any cash or asset they are holding overseas, there will be a one time tax rate for them to repatriates that to the us. So President Trump obviously hopes that money flows back into the us. There will be more jobs here. There are questions being asked about that because even if the company has extra money it does not mean it will reinvested in a way that will actually create jobs on the ground. Weve got to leave it there. Apologies. We will have further opportunities because while that legislation has been signed through and you sort paul ryan announcing that a few minutes ago, the Senate Must Still vote on that. We expected to approve but we will bring you further coverage. I thought i would start this by talking about the weather conditions across north america. This quite a lot going on. Weve got a possibility of thunderstorms in the next few days. Weve got this big winter storm ringing heavy rain and snow. A little bit might reach Northern California but the south is expected to remain dry. The windows light which is good news for the firefighters. It will increase from a northerly direction to 60 mph. We will keep you up to date on that. This is what i was talking about earlier on in the bulletin. It will bring thunderstorms to the south east of the United States on wednesday. Still capable of producing strong downdraughts of of torrential rain. A cross into the south east of asia this tropical or am has brought up to a metre of rainfall. It will give us some heavy rainfall. It will give us some heavy rain with this glancing blow to southern vietnam. More heavy rain moving into central and southern philippines and this could cause further flooding philippines and this could cause furtherflooding problems. Into europe, weve got quite a contrast. To the south we got heavy rains and storms. To the north and the west, wintry conditions. I pressure is controlling the weather. Largely fine unsettled but for problems across parts of france and germany. Weve got this weather front slowly moving southward. It will bring outbreaks of rain in central areas. Find it it will be a little bit colder with some sunshine for Northern Ireland and scotland. To the south skies will remain cloudy. 0ther the south skies will remain cloudy. Other values here. As we head into thursday it will be a pretty benign picture. Rather cloudy skies in southern and western areas. By chile across this corner. There will be some sunshine in the south. The milderair some sunshine in the south. The milder air will spread across the uk. You can see a fool Weather Forecast rate here in about half an hour. Hello, im ros atkins. This is 0utside source. Harvey weinsteins. His former personal assistant has spoken to the bbc about how he would respond to allegations of sexual misconduct. He said nothing at all had happened and he swore on the life of his wife and he swore on the life of his wife and his children, which was his best get out ofjail card that he used quite a lot. In another bbc interview, President Trumps National Security advisor has this message for kim jung un. All options are on the table and we have two be prepared, if necessary, to compel the denuclearisation of north korea, without the cooperation of that regime. And we will report on saudi arabia. The saudi military says its intercepted another rocket that was fired into saudi arabia from yemen. Well talk to bbc arabic. And well report from seoul after the death of one of south koreas biggest pop stars, in a suspected suicide. That story now in saudi arabia. The saudi military says its intercepted a rocket that was fired into saudi arabia from yemen. Houthi rebels have confirmed they were targeting a gathering of seniorfigures here. At king salmans official residence in riyadh. Remember, last month, a similar missile came close to hitting riyadhs airport. This is one of several unverified videos. A lot of people saying this is the smoke caused by the interception of that rocket. And then these are people who witnessed what happened. I heard a big bang. Suddenly, after around 30 to 45 seconds, i heard a next sound, a little thud, then i came up here up the tower and then i saw some people here looking at that place. Its a road leading to the airport, and we saw white smoke. I see the big explosive outside and icy outside the people coming out. We saw smoke up here on the rooftop. The context to all of this is that on one side of the conflict in yemen is the government supported by a saudi led coalition. 0n the other side are houthi rebels, who are backed by iran. But iran denies saudi claims that it supplied the rebels with these rockets. Bbc arabics rasha qandeel. The potential that the iranians are helping the houthis rebels is more than the other times. This rocket that was fired today, it is basically a rocket that has been modified and the rockets made in russia. So if you trace back the history of this rocket, there is a big potential that according to the saudis, iran has been providing the houthis. Newsnight arabic speaking toa houthis. Newsnight arabic speaking to a saudi official thinks that the rockets are not being smuggled as one piece, but in three pieces, and this makes it easier to smuggle. So the evidence of saudi saying iran has provided the houthis with the rockets, this time is stronger than other times. That saudi official you are talking about, did he talk about the blockade the saudis have been putting in place . He was not, he was just talking about this is the third rocket fired from yemen by the houthis towards saudi arabia, and riyadh. And the blockage has been talked about by the un big time because the un has recently released another report saying that the coalition, led by saudi arabia, killed in one month 126 civilians. A huge toll compared to the entire history of this conflict in 2015. |j mentioned the blockade because this is the primaryjustification for it, the fact that the rebels are getting weapons smuggled in. They are, the houthis are pushing towards that this is reaction, not an action, to the blockade provided by saudi arabia and yemen recently, especially after the assassination or targeting of assad. How do we see this behaviour of the houthis in the context of the former president of yemen a couple of weeks back . The hugest escalation because even the houthis themselves that used to be su btle houthis themselves that used to be subtle about the targeting saudi arabia inside saudi arabia, this time it is like pride. They say that this moves the battle one stage up and they are ready for the reaction of the coalition in yemen by the armies and the forces that saudi arabia is leading. So it might be a new phase, a new stage, worse, the conflict between saudi arabia and the houthis on the ground. And the ambition of the houthis is to defeat the government and control all of yemen, or most of it . This is what they say, especially that in the last few days, there have been reports that one of the very important points in yemen has been lost to the coalition by the houthis, and that means that the battle is getting fiercer. And since there is no other support by the others, the houthis runaround. If there is support by iran, lebanon, it will show on the ground in the coming months, isuppose. It will show on the ground in the coming months, i suppose. You can get more on that through bbc arabic.

Dont forget, you can get much more detail on our top stories on our website. The uk government has had its first full Cabinet Meeting on what it wants the uks final relationship with the eu to look like. The referendum was back injune 2016. Given that the referendum was almost 18 months ago, some have suggested this might have happened sooner. Scottish first minister Nicola Sturgeon tweeted that the delay is negligent. We know a bit more about the nature of this meeting. You can do the maths, none of them would have been able to talk for that long. The meeting took place at 10 downing street. With the Christmas Tree just outside. Prime minister theresa may told the ministers a deal which secures the best possible trading terms with the eu, enables the uk to set rules that are right for our situation, and facilitates ambitious third country trade deals. Iain watson is in westminster. I guess the catch here is that the European Union is already saying, you cant have your own regulations if you want to do business with us. That is right, clearly. While this cabinet discussion was taking place, one and three quarters hours, the chief negotiator of the eu Michel Barnier publish something circulated the eu leaders, which is best. This little chart. Effectively, he says, we cannot have a norway type trade deal because we will not accept freedom movement. And we cannot have easily steal because we do not want to pay a great deal of money into the European Union. We cannot have a turkish deal because we want to strike our own trade deals and we cannot have the same customs relationship as turkey, which he says leads to a logical conclusion, we become the british version of canada. The problem with becoming canada. The problem with becoming canada that trade deal which is seen as ambitious seven years to negotiate with European Union, it says very little about Financial Services. In a separate interview with the Guardian Newspaper and subcontinental newspapers, Michel Barnier made it very clear these type of trade deals do not include Financial Services and that is a vital sector of the british economy. The response from downing street is simply this, that they would expect this type of approach as an opening gambit in negotiations, based two ahead of the formal trade talks, but they say is that everything is up for negotiation and the Prime Minister was emphasising a part of the agreement this morning was an ambitious trade deal which would be much better than a trade deal that canada has and would include Financial Services, that is the sort of thing she wanted. As she has done before, she ruled out becoming a new norway because she does not want simply to accept eu rules. We are now getting a clearer idea of the relationship between britain and brussels. What the Prime Minister had to sort out was the real inch relationship between her own ministers. 0n the surface, it looks like an agreement, but a bigger debate to be had and maude discussions, no final decisions take taken discussions, no final decisions take ta ken today. Discussions, no final decisions take taken today. Do we want to get a massive divergences, if need be, between eu rules and regulations at the end of a transition period . Something the foreign secretary is said to favour. Some unity within the cabinet, which may come under strain later, but differences between the cabinets position and the position in brussels. Help out the position in brussels. Help out the viewers thinking, how is this conversation not happening considerably earlier in the process . Two different points of view on this. The official line from downing street is simply this, they were discussing bay is one issues about the money and relationship with ireland phase one. They said there was no point having a wider discussion about the end point until negotiations officially moved on to the second phase. More cynical people would say because of those differences in the cabinet that i mentioned between the chancellor and the brand secretary and others, theresa may was making sure she did not have to have a big argument and possibly cabinet resignations before she had to. Members of parliament have widely criticised social Media Companies for not doing enough to combat hate crime. They are accused of providing a platform for extremism. Harmful content online ta kes cou ntless forms, but not all of them are illegal. There is the hate speech that attacks individuals on the basis of attributes such as disability or gender. That is quite separate from extremist content, which propagates the worldview of those ranging from neo nazis to so called islamic state. How easy is it to find this material online . Very easy indeed. 0ne campaigner working with mps on the issue believes social media platforms youre vulnerable adults into the extremist web. How big an issue is soft extremism . It is a significant issue because actually the material clearly is not removed, it is not illegal in the eyes of social media providers. The other factor is their algorithms are diverging individuals who may have an aggressive worldview, and the algorithms direct them to join other groups who may have similar content. Today mps called Tech Companies as part of an enquiry into hate crime. The Committee Chair set twitter still had not removed a an offensive to eat it was warned about in march. That is still on your platform. Why is it . I dont know the answer to that question. I really do all think we should kill a tory. Think of the benefits were we to killjust one tory. That is on twitter. Your home say she will not tolerate violent threats of individuals or groups. How does that comply with your code . We have 500 million tweets a day, 330 million users. Twitter is used in multiple languages. You are actively recommended what is effectively raises material into peoples timelines. We will look at that and get back to you with a good and solid response. Isnt the truth that your algorithms and the way you want to attract people is doing that grooming and radicalisation . That is not how facebook sees it. I recognise we have a problem which is a shared problem with civil organisations of addressing that person who may be going down a channel which can lead to them being radicalised. Mps have a personal stake in the fight against harmful content online. But its not clear that turning tech giants into centres is the best way to safeguard democracy. Next, a new study. The number of cheeta hs in the wild in Southern Africa is falling. Researchers analysed two million pieces of data across six years in namibia, botswana, south africa and zimbabwe. This is what they found. For instance, the cheetah population is around 3600, it might sound like a lot but it is down and as you can see, one of the biggest issues is only 18 of the animals are in places where they can get the protection they need. Here is the lead author of the study. The situation is a bit complicated. They are rare and lucid and competing with larger predators. A majority of their range is unprotected. They are facing a risk from habitat loss. That is from agricultural expansion and lifestyle production. It reduces the availability of wild prey and increases the likelihood of conflict with humans. 0ur increases the likelihood of conflict with humans. Our study found that while the majority of farmers do not persecute the animals, those that do have the potential to cause serious impact on the population. This could be framed in a hopeful way. It could be framed in a hopeful way. It could be the future of the cheetah rather than that by creating and maintaining tolerance for the species. This has the benefit of raising awareness in the general public about the precarious nature of the population of cheaters in the wild.
