1—0 to tottenham. reports from italy say anti—doping prosecutors there have requested a maximum four—year ban forjuventus midfielder paul pogba after he tested positive for testosterone. that length of ban is standard, but can be reduced to two years if an athlete can prove their doping was not intentional or if they provide "substantial assistance" to help investigators. pogba, who's now 30, has been provisionally suspended since he tested positive after a game in august. it's one of the most iconic clubs in world football, and with eight league titles to its name, one of brazil's most succesful as well. add to that they're seen as the team with the most goals in football history. over 500 of them scored by its most famous son pele. i can't forget their three copa libertadores titles as well. however, the good times at santos are over for now. on wednesday, for the first time in their iii—year history, santos were relegated from brazil's serie a. here's our south american football expert tim vickery in rio. the club was founded the very night that the titanic went down, and now santos find themselves relegated to the second division. they are a miracle. the city of santos by brazilian standards is a very small city. it's less than half a million. it's the port on a good day about an hour's drive from the metropolis of sao paulo. greater sao paulo has 50 million people plus, so the fact that for so long santos were able to compete and win against the big cats from the city is an extraordinary story. i suppose really it kind of belongs to the era when burnley can belongs to the era when burnley can be the champions of england and nottingham forest could win the european cup. and really over the last few years, as financial gaps have opened up, there isjust a group, a small group of the biggest brazilian clubs that have broken away. they are monopolising the major titles, and it's become increasingly difficult for santos to compete. the timing is very, very cruel. this is the first season since the death of the great man, the death of pele. he lives in a mausoleum which is pretty much in view of the santos stadium, and that cannot have been good viewing for the late pele in the first season without them, santos in the second division. but it was i fear a question of time. formula i's governing body has ended its compliance inquiry into mercedes team boss toto wolff and his wife, the fi academy director susie wolff. the fia had launched an inquiry into a magazine's claims that rivals believed the couple's relationship presented a conflict of interest in the sport. but on thursday, the fia said it was "satisfied" fi had measures in place to protect against such issues. the statement added that there was "no ongoing investigation" into the matter. some good news for emma raducanu, who will make her comeback to the tennis tour in auckland in the first week of january. she's been awarded a wildcard into the asb classic in new zealand. the 2021 us open champion has been out of action since april and has fallen to 296 in the world rankings following three operations. the australian open, the first grand slam of the season, begins on january 14th. and that's all the sport for now. back to you, christian. thank you very much indeed. the prime minister has been on the defensive today after the dramatic resignation last night of his immigration minister. robertjenrick has quit over the rwanda deportation policy. in his letter to rishi sunak, he said the newly—proposed legislation does not go far enough, and will not allow the government to override international laws, which so far have stopped them sending asylum seekers to central africa. this morning, rishi sunak summoned reporters to downing street to insist that his draught legislation is the right plan and will prevent most legal challenges. we simply cannot have a situation where our ability to control our borders and stop people taking perilous journeys across the channel is held up in endless litigation in our courts. but that will be enough to quell members of his own party who are fed up with his leadership on this issue? among them suella braverman, his former home secretary and a close ally of robertjenrick. she told the bbc the policy just isn't doing enough. we have made promise after promise. we have put forward plan after plan. they have all failed, and we have now run out of time. this is an issue of huge importance to the majority of british people who desperately want us to fix it. but on the other side of the party, there are members who think the pm has been hoisted by his own petard. one of them is lord garnier, the former solicitor general. - ijust find it difficult to think it - acceptable that we should be passing a bill of this nature when it makes | political nonsense and it certainly| makes legal nonsense. you're sounding quite... we've got a really honourable and decent and hard—working| prime minister who is trying tojuggle the elements- within the conservative party who are deliberately trying . to make his life difficult. jo—anne nadler is a former conservative party adviser, now author and commentator. lovely to see you. thank you for coming on. he called this press conference, the prime minister today, seemingly to reinforce his authority in the party, so we'll has the reaction been?— the reaction been? well, i think very mixed _ the reaction been? well, i think very mixed because _ the reaction been? well, i think very mixed because the - the reaction been? well, i think very mixed because the devil. the reaction been? well, i thinkl very mixed because the devil will very mixed because the devil will very much be in the detail of this proposed legislation. and there is a lot of detail to it, and it's quite technical. and as lord garnier was saying, it is quite complicated in legal terms. and in a sense, the problem for rishi sunak is he raised expectations upon coming into the prime minister ship that he would in as many words stop the boats. and this was a huge and ambitious claim to make and one which i think many people felt immediately was something that he was unlikely to be able to achieve unless he did take a sort of dramatic approach that we've had advanced by suella braverman. now he has not seemed willing to do that, and it had to be seen with a couple gated nature of these latest proposals are as he says only an inch away from what the former home secretary wanted. lard inch away from what the former home secretary wanted.— secretary wanted. lord garnier is the former— secretary wanted. lord garnier is the former solicitor _ secretary wanted. lord garnier is the former solicitor general, - secretary wanted. lord garnier is the former solicitor general, so i secretary wanted. lord garnier is i the former solicitor general, so he is the man advising those on the more moderate wing of the party and he has already said he won't vote for it. when it comes to the house, rishi sunak can only afford to lose 28. he backed off making this a confidence vote today. was that a sensible decision?— confidence vote today. was that a sensible decision? well, in a sense it is for all intents _ sensible decision? well, in a sense it is for all intents and _ sensible decision? well, in a sense it is for all intents and purposes - sensible decision? well, in a sense it is for all intents and purposes a l it is for all intents and purposes a confidence vote. we can call it what he wants, and of course even with a plate and the significance of it. but as i say, because he had raised this issue and made it so totemic and such an important cornerstone of his success of his own leadership, is inevitable that this second attempt under his leadership to get this problem fixed will receive a kind of political scrutiny that it might not otherwise have done. and there also is the important point, in fact the rather more important point in this sense, that this is a real problem that people are concerned about. and so what we've got going on here is a kind of an interparty dispute in westminster which can make the conservative party feel even more remote from those people who actuallyjust want to see a resolution to this problem. so this is a very, very thorny problem for rishi sunak and his leadership. problem for rishi sunak and his leadership-— leadership. you think 'ust very cuickl leadership. you think 'ust very quickly «mi leadership. you think 'ust very quickly could it h leadership. you think 'ust very quickly could it lead _ leadership. you thinkjust very quickly could it lead to - leadership. you thinkjust very| quickly could it lead to another leadership challenge? welcome on my own view is i — leadership challenge? welcome on my own view is i think _ leadership challenge? welcome on my own view is i think that's _ leadership challenge? welcome on my own view is i think that's more - own view is i think that's more unlikely than likely before another election. the conservative party now feels that it's pushing towards a defeat and those people who want to become the next leader of the party will have to ask themselves what they have to gain from creating more chaos before that election. so i think that in the short term is relatively unlikely, but it is a very febrile situation. and there are people who would like to force the issue. , ~ ., ., ., the issue. interesting week ahead of us. thank the issue. interesting week ahead of us- thank you _ the issue. interesting week ahead of us. thank you very _ the issue. interesting week ahead of us. thank you very much. _ around the world and across the uk, this is bbc news. bbc news, bringing you different stories from across the uk. billed as the future and powered by green energy, this is just a taster of what's to come in the south—west. vehicles running on clean power. some are the first prototypes of their kind in the world. others are already in operation. we see lots of electric cars on the road right now, but it's the other bigger, heavy vehicles and the vessels, they will start to become clean probably post—2030. and we're going to see a big shift in how things are. and this, another world first. we have built a zero—emission all—terrain off—highway vehicle which is destined for places like the mining industry, the quarrying industry, airport operations. and at the moment, we have a prototype vehicle which is driveable and is the first one in the world. for more stories from across the uk, head to the bbc news website. you are watching the context. it's that time, for al decoded. this is the time of the week when we look in depth at some of the most eye—catching stories in the world of artificial intellligence. we're going to begin tonight with this story from the team at the new york times, who report that the technology is now advacning so rapidly and in so many directions that legislators in europe are the united states are now struggling to keep track and to regulate it, with big implications down the line. the guardian reports that google's ai offering gemini, which is only yet available in the united states, outperforms chatgpt in most tests and will perform with advance reasoning. gemini will soon be folded into most google product, including the search engine. fortune magazine looks at how ai has developed in the workplace. they report that in some sectors it has become so indispensable that nearly 60% of the workers who use it say they'd rather take a 10% pay cut than go without it. the bbc news website has a piece today on the rise of ai—powered clones. the idea is that very soon we will be able to deploy our own digital clones to do the more mundane jobs that take up most of the day, freeing up more time. these clones which will learn from you. all your habits and behaviours will be indistinguishable to the client. scientific american raises the alarm on malign chatbots which have been trained to find ways through the built—in restrictions of other chatbots. supposedly these malign actors would learn prompts that would unlock information on how to build a bomb, how to synthesise methamphetamine or how to launder money. and finally a warning from the new scientist, which says beware what you type while attending a virtual reality meeting. the ai can now work out subtle hand movements to reveal sensitive information, passwords and log—on details. good job i'm not in virtual meetings very often. stephanie hare, author and commentator on technology and artificial intelligence. lovely to see you. so this story in the new york times, we are losing the new york times, we are losing the battle to regulate ai because it is moving so fast. in fact if you talk to legislators in the us, which we have done actually on this programme, they would open look that they barely understand how it works now. so how likely is it they can draw up legislation for things we don't even know about?- don't even know about? well, certainly the _ don't even know about? well, certainly the american - don't even know about? well, - certainly the american legislatures are not going to a passing any laws any time soon, not until the election is long over. but over on this side of the atlantic, we may see some movement tomorrow from the european union. we were hoping he would get it today. the negotiators have been haggling for 22 hours straight over the eu ai act. they call time is everyone home and are starting tomorrow at 9am as we may get landmark legislation tomorrow. they already had a draught of this which they worked on for three years, and it was already out of date. it did not even mention opened al's chatgpt. the great they work for the night and got to something but next week you could already be out of date. but next week you could already be out of date-— out of date. they've already got something _ out of date. they've already got something that's _ out of date. they've already got something that's been - out of date. they've already got something that's been added i out of date. they've already got i something that's been added since chatgpt came in on foundation models, was looking at the models that are used to train large language models. looking at the kind of data that used and we know that's really contagious is because most of it is still when people are not being comes for it. open ai have gotten a mark on that so we might see some movement. but there's a lot of things that are up for grabs i suspect we probably took about it more next week because anything we say now could all be rendered useless by tomorrow in the haggling. if there is a vacuum, as some of the policy makers think that there is, then clearly it is left to the ai companies themselves to police the rules. they are not very good at that when it comes to social media. what could go wrong?— that when it comes to social media. what could go wrong?

it means text, audio, images, video and code. it can who were them up and do cool things with them simultaneously. it's only going to be coming back to people in terms of the output is a generates an in terms of texting code which is already going to be very useful. so you could for instance point your phone at your physics homework, that's one of the examples they gave, and it could look at it and market. that's crazy. it's like having a teacher in your phone. so again this will be a massive challenge for actual teachers who are out there trying to chat but it could be an incredible learning tool for students worldwide.— learning tool for students worldwide. �* ., , ., worldwide. and for my wife and could not turn your — worldwide. and for my wife and could not turn your phone _ worldwide. and for my wife and could not turn your phone off— worldwide. and for my wife and could not turn your phone off in _ worldwide. and for my wife and could not turn your phone off in church i not turn your phone off in church last week at carol's. can just show you
