greenhouse gas emissions. hundreds of estonians take to icy waters in hopes of setting a world record in "ice" swimming. hello and welcome if you're watching in the uk or around the world — and stay with us for the latest news and analysis from here and across the globe. we begin here in the uk. the uk prime minister borisjohnson has chaired a meeting to look at the uk's contingency plans, in the event that a deal can't be reached in post—brexit trade talks. trade negotiations with the eu — which are currently stuck in stalemate — are expected to end tomorrow. the sunday deadline was set by mrjohnson and european commission president ursula von der leyen after the pair met in brussels during the week,

after months of talks failed to achieve an agreement. mrjohnson said the eu needed to make a "big change" over the main sticking points on fishing rights and business competition rules. while mrs von der leyen said no deal was the most probable end to "difficult" talks. the ministry of defence has also confirmed that four royal navy ships are on standby to protect british fishing waters if no agreement is in place when the transition period ends on the 31st of december. here's our political correspondent, jonathan blake. in downing street yesterday, the prime minister chaired what has been described as a stock—take on the uk's readiness to end its relationship with the eu without a trade deal. visiting a manufacturing plant in northumberland, he said while it's not the outcome he had wanted, britain would be prepared. four royal navy patrol boats will be ready to protect uk fishing waters, it was confirmed last night, as part of what the ministry of defence said was "extensive preparation for a range of scenarios "at the end of the transition period".

in brussels, the eu rejected borisjohnson‘s attempt to meet key leaders individually to try to make progress. while some member states sound more worried than others about a no—deal outcome, they are united in their approach. plans to manage traffic queues are being tested this weekend — one of many possible consequences whether or not a free trade agreement is reached. but still, so much is uncertain with less than three weeks to go. jonathan blake, bbc news. our political correspondent helen catt said in the last 48 hours there seems to have been a hardening position on both sides of the negotiations. i spoke to her earlier. think about the so—called scallop wars, clashes between fishermen in devon in england and in normandy in france over the fishing of scallops in the channel. so there are instances of this in the past. but it certainly seems that in the last 48 hours, a sense of a hardening of position of both sides. in the uk, decided that

borisjohnson has chaired that committee to take stock of no deal of readiness and this news about the naval boats on standby does suggest that it's trying to send this message of, "look, the uk is ready, "it is prepared to go it alone." in the same way, that on the eu side, emmanuel macron and angela merkel saying, "no, we're not going to have "individual conversations with borisjohnson" hardens up the position of, "no, we are a solid block and we are not "going to be picked off, if you like, one by one. "we are standing united." so it does seem to be that in public certainly, a bit of a hardening of position on both sides. if the uk's deployment of royal navy ships to police its fishing water post brexit, resulted in clashes with french fisherman, it wouldn't be the first time the country has come into conflict over fishing. the cod wars were a series of confrontations between british

ending in the 1970s. tom watson was skipper of the wyre victory fishing vessels during the cod wars, and has since served as national federation of fishermen‘s organisations representative for the northwest in brussels. thanks very much forjoining us. first of all, on news that the royal navy might be deploying ships, do you think that is really necessary? yes, ido, but you think that is really necessary? yes, i do, but the name of the ship wasn't the wyre valley, it was the wyre victory. but yes, i think they will have to deploy the navy to protect the fisheries. and you were involved with the cod wars. tell us what you are involved with? well, we tried to keep fishing when the icelandic government decided that they were extending their limits to protect the stocks. as far as we

we re protect the stocks. as far as we were concerned, protect the stocks. as far as we were concerned , we protect the stocks. as far as we were concerned, we were entitled to keep fishing, so we had several conversations with the gunboats that came out. they resorted to trapping oui’ came out. they resorted to trapping our gear away, and we resorted to a few tactics, trying to stop them. i managed to disable a gunboats when he was trying to catch my gear once. and we had another brush in with a gun boat when we were both locked alongside each other throwing nuts and bolts and anything we could get hold of at each other. are you worried that something similar could happen again now? possibly. it depends how it is handled, but possibly, yes. buti depends how it is handled, but possibly, yes. but i don't think it would get to be as serious as what it was in the cod wars. where exactly would you expect to see an escalation, and why do you think the royal navy is needed? well, i mean, when the president of the european union gave her a little aside about us union gave her a little aside about us being an independent coastal

state and sovereign state, she should understand that the british government is duty—bound to enforce the international ruling that came out of the cod wars, which is that an independent sovereign state is responsible for, and should control, the fisheries inside its own territorial waters. and for the benefit of its own people. so do you think that should be implemented immediately? are you supportive of a new deal exit? yes, definitely. the europeans, and particularly the french, need to understand that we will decide what they catch up to december 31, and it won't be what they catch now. we aren't saying they catch now. we aren't saying they should be carried out completely, but their coaches need to be reduced dramatically back in favour of the british home fleet. to be reduced dramatically back in favour of the british home fleetm you're going to be in a partnership, though, with the europeans, we have to give as well as take, don't we? one thing we have is water, and therefore, that as i was been the deal, hasn't it? there has to be an

exchange of resources. we have been giving them... well, we haven't been giving them... well, we haven't been giving them... well, we haven't been giving them. they have been taking. the british were outmanoeuvred in the negotiations forjoining the common market back in the 70s. that was the worst thing that ever happened to us. there was never any concern shown when the british fishing fleet was destroyed and all our men were put out of the work for the greater good ofjoining what was called the common market, as it was supposed to be. it is worth mentioning... sorry. obviously, i understand you are speaking on behalf of your industry, but fishing isa behalf of your industry, but fishing is a very small proportion of the british economy overall, and the projections that have come in from going into a known no—deal brexit area going into a known no—deal brexit are a huge fall in gdp from other sectors of the economy. surely there has to be balance and how we go forward ? has to be balance and how we go forward? well, i don't think there's ever been any intention of banning these people together, but they shouldn't be allowed to control the fisheries as they are now. that's

one of the things we have to take into consideration. these are our waters and our fish. into consideration. these are our waters and ourfish. we into consideration. these are our waters and our fish. we control who catches whatever. you're not worried you're not worried that having gone from a0 years of close partnership with the europeans and a whole range of measures, that we are now about to enter tense... no, i am glad. unnecessary fights in the water? no, i'm glad. it's about time we broke away. this european union is the soviet union with money. tom watson, skipper of the wyre victory fishing vessels. thank you for your time today. the us supreme court has rejected an attempt to overturn the election results — which was backed by president trump and more than 100 republican members of congress. the state of texas had filed a lawsuit arguing that voting results in the battleground states of georgia, michigan, pennsylvania and wisconsin — all won by president—electjoe biden — were invalid. but the court said texas didn't have a good reason to bring the case. in a tweet, mr trump accused

the court of letting down his republican supporters, and showing neither wisdom or courage. the pfizer biontech coronavirus vaccine has been authorised for emergency use in the united states — by the us food and drug administration. the agency had come under intense pressure from the trump administration to approve the vaccine. our washington correspondent nomia iqbal has more. this emergency authorisation has taken a bit of time. the fda has approved the vaccine, after being advised to do so by an outside advisory group of independent medical experts. they had analysed the effectiveness of the vaccine. it also looked at the potential side effects, including those reports of two british patients who had allergic reactions after receiving the pfizer jab. and after the recommendation came this intense political pressure by president trump. he had called the fda

a "big, old slow turtle". he was demanding that they approve the vaccine. he had this to say, once that green light came. the first vaccine will be administered in less than 24 hours. the governors decide where the vaccines will go in their state and who will get them first. we want our senior citizens, health care workers, and first responders to be first in line. i promised that we would produce a vaccine in record time, before the end of the year. they said it couldn't be done. but with today's announcement, we have now achieved that goal. there is pressure for protection because the pandemic is surging here. on wednesday, one day alone, there were more than 3,000 deaths and mr trump is keen to turn those headlines away from americans dying to americans being vaccinated as he leaves the white house. and we will now see what will be the largest vaccination campaign in us history. people who are over 16 will receive the jab.

health workers and the elderly living in nursing homes will be the first to receive the vaccination. those with severe allergic reactions are recommended not to take the vaccine. but the us is also waiting for approval on another vaccine made by the company moderna, and that's expected to go through the same robust approval processes next week. anyone arriving in the uk from the canary islands must now go into quarantine. the new rules came in to force at four o'clock this morning — after the islands were removed from the travel corridor list because of a rise in covid cases. however, the isolation period is being cut from 1a to ten days, as john mcmanus reports. with december temperatures in the low 20s, life is still a beach on the canary islands. but for holiday—makers returning from there to the uk from aam this morning, the welcome home is going to be a bit chillier. they'll have to go into quarantine after the canaries were removed from the uk's travel corridors list

because of rising infections there. tour operator tui says it has around 5,000 uk customers on the islands. many will have been unable to change their plans to beat the deadline. there is some good news, though — the time spent in isolation for those returning from high—risk areas will be cut from 1a days to ten. the relaxation also applies to those who have been in contact with virus carriers. the change has already started in wales. the rest of the uk follows on monday. wales is facing a serious challenge, though. with more than 1,900 people in hospital with the virus, there has been a warning that another lockdown may be imposed after christmas if current restrictions, which include school lessons moving online from monday, fail to work. if those measures do not succeed in turning the tide of the virus, then it is inevitable that we will have to consider a move to alert level four

immediately after christmas. in parts of london and the south east, cases are also rising, particularly among secondary school—aged children. past experience shows this can precede a jump in infections for older age groups. elsewhere in england, 67 local authorities which are under the highest tier 3 rules have been given the green light from the government to offer rapid result testing programmes to help them cut transmission rates. ministers say the move follows a successful trial in liverpool, but there are concerns over the tests after preliminary data from the city showed they had missed 51% of covid cases. the government, though, insists the tests are reliable and can help quickly detect the virus in those who don't have symptoms. john mcmanus, bbc news. councils under england's toughest coronavirus restrictions are set to roll out mass testing programmes from monday.

67 local authorities have received government approval for the voluntary scheme — which uses the rapid response test — after a successful trial in liverpool. the virus is on the rise in parts of wales, london and the south—east, and the east of england. the headlines on bbc news: one day left to secure a trade deal. talks resume in brussels with both sides warning they're unlikely to reach a post—brexit agreement by tomorrow's deadline. the us regulator authorises the pfizer biontech coronavirus vaccine — donald trump says it'll be rolled out immediately. travellers returning to the uk from spain's canary islands must self—isolate — some fear they won't get back in time to avoid christmas in quarantine. the uk, france and the un will be hosting a virtual climate meeting later. around 75 world leaders will attend to lay out their plans for cutting greenhouse gas emissions. the summit marks five years since the adoption of the paris climate agreement,

as our chief environment correspondent, justin rowlatt, explains. applause there were celebrations on a global deal on climate was finally done in paris five years ago today. for the first time, the whole world agreed that all nations need to play their part in keeping climate change to 1.5 celsius. the only problem was the commitments made in paris weren't enough to do the job. in fact, until this year, co2 emissions have been steadily rising. the woman who helped secure the paris deal said action is urgent. science has been telling us for decades, "we're running out of time, we're running out of time. but now it's really, really, really dangerous. in paris, world leaders agreed to get together every five years

to try to up their game, raising the tablets raising the targets for cutting emissions. that was to have happened at a conference hosted by the uk in glasgow in november this year. thanks to the covid pandemic, that has been put off until next year. so instead, world leaders will be gathering virtually, today. boris johnson, the uk prime minister, will be chairing the meeting from a room here. the future of our planet is at stake and mrjohnson will be hoping that countries will bring bold targets to the table. that will make getting a really ambitious global both targets that will make getting a really ambitious global deal on cutting emissions in glasgow next year much more likely. myles allen, the head of the climate change programme at the environmental change institute, told me earlier that he hopes one of the key things to come from the summit is a refreshed

approach to the issue. i hope one of the main things to come out will be a new way of thinking about how we deal with climate change. the conference coming up next year has been very much billed as the conference where the private sector gets brought in to dealing with the problem. we've had all these pronouncements from governments. in the end, governments don't emit, it is companies and individuals who emit and so on. so, we need actually to broaden it out from governments making commitments to companies changing the way they do things. and, above all, we need to get the fossil fuel industry itself inside the tent, helping with the solution to the problem caused by the products they sell, rather than being part of the problem. specifically, what would you like to see from them? well, i would like to see a recognition. and, increasingly, companies are making rather mealy—mouthed to acknowledgements that they have to get to net zero, along with the rest of the world. i would like to see, rather than just a number, i would like to see a plan. i don't think any major fossil fuel company has a plan for getting

to a durable net zero future. and they've got the resources to do it. energy is about 10% of the global economy and 85% of our energy is still fossil fuels. that's down from 87% in 1990. this is an enormous industry. it's the one institution in the world that has the resources, access to capital, engineering capability to stop climate change, it's the fossil fuel industry. and right now, governments are setting all these targets, but they aren't even seriously asking the industry to try. of course, all governments, including here in the uk, are facing massive covid challenges and economic challenges. it's going to be tempting for everyone, isn't it, to say, "look, this is still some way off in the future, it's expensive "and difficult, we can't actually do much right now?" which is precisely why we should not depend on throwing public money at this problem as the solution. obviously, public money is helpful

to get a technologies rolling, to get technologies rolling, to get them moving. and the way we subsidised wind and solar in the early years was incredibly effective at getting prices down there, but in the end, you've got to get private companies on board. and that isn't going to happen by expecting companies to do it out of charity. in the end, they're just going to have to be told to get on with it. reports from iran say the journalist ruhollah zam has been executed. he was accused of stirring up violence during anti—government protests in 2017. ruhollah zam, whose amadnews feed had more than a million followers, had fled iran and been granted asylum in france. but last year the revolutionary guard said they'd seized him in iraq and taken him back to tehran.

archaeologists have unearthed more sections of an extraordinary aztec tower under the centre of mexico city. it's been described as one of the most impressive historical sites in the country, as gail maclellan reports. behind this nondescript door in the center of mexico city lies a building as historic as it is gruesome. it was built when the city was called tenochtitlan, and ruled by aztecs over 500 years ago. it is made of skulls. the tower was first discovered five years ago. now more than 119 skulls have been found. archaeologist raul barreras describes how they were made out. translation: this is the external facade of the skull

tower on the east side. these skulls were mounted on a fence—like structure, and set in place with mortar. archaeologists were surprised to find skulls of women and children, suggesting that some of the remains were of people killed in ritual sacrifices aimed at appeasing the gods. the majority, though, were young men, possibly captured warriors. these skulls are placed facing outwards on the tower in an effort to terrify enemies. but their power didn't last. the spanish conquistadors captured the city in 1521. last night, hundreds of estonians took to icy waters in hopes of setting a world record in "ice" swimming. 505 participants took part in a relay of 25 metres each in a pool of icy water at former imperial russia's submarine shipyard following the ice swimming festival. aivar tugedam is an ice swimmer and the organiser of the record attempt.

thanks forjoining us. what happened last night? well, we beat the finnish people, because the previous record belong to them, and we doubled it. according to our information, they had a record to 250 participants, and now this belongs to estonia and estonian winter swimmers, and the new record is 505. and what on earth is the appeal? because it sounds pretty terrifying to me. it is really easy, because the idea was to have a relay, and every person who participated has to swim 25 metres in the sea water, according to our information. this isa according to our information. this is a degrees at the moment. so it is

plus degrees, above zero, so it should not be problematic. plus degrees, above zero, so it should not be problematicm shouldn't be problematic, but it is extremely cold! no! isn't it extremely cold! no! isn't it extremely unpleasant? no, i disagree, because it is not ice, and outside, it is —a, so it is plus 8 degrees warmer climate. you have to do... don't think, just decide, go into the water and enjoy the swim. it will be very good for the health, and maybe against corona as well. so maybe this is the estonian vaccine! why do you think it will help against... i don't think we should be suggesting false coronavirus cures, but is it because you think it helps boost your basic strength,

your immunity and so on? yes, because it improves your immune system and you are not so... how do you say in english? addicted to the cold and flu and so on. you will be much more healthy. this is also why there are people who are running in there are people who are running in the wintertime all over the district. so i would recommend 100% to two, or to try it, and if you are lucky, you will like it, and you will not choose coffee for waking up in the morning, but you will decide to do in the morning, but you will decide todoa in the morning, but you will decide to do a little swim, 30 seconds, one minute orso, and to do a little swim, 30 seconds, one minute or so, and you have good health and live long. 0k, health and live long. ok, we will leave it there. many thanks indeed forjoining us. great to see you on location. i have to say, i have indian finnishgenes, and

iama say, i have indian finnishgenes, and i am a warm water, sunshine person. i'm sure it is genetic! it is all in your head! thanks for watching. this is bbc news. hello there. turning more and settled this weekend. wet and windy weather spreading in of the atlantic, but today looks pretty quiet. quite a bit of sunshine across the western half of the country. still a bit of clout and showery bursts of rain across the east, courtesy of that area of low pressure. this ridge of high pressure. this ridge of high pressure will bring the sun to the west, and this low behind me to send av west, and this low behind me to send as wet and windy weather. it has been bright to the morning. parts of wales in the south—west, sunshine encroaching, but it stays damp and cloudy across north and eastern scotland, most of eastern england. temperature wise, and the cool side across eastern areas. seven or 8 degrees, closer to nine or ten. this evening and overnight, the clearer

skies encroach eastwards. it will turn drier here for the eastern half of the country. wet and windy weather sweeping into the west and south—west by the end of the night, and here, temperatures will be rising. seven to 9—10, turning chili and a clearer skies across central and a clearer skies across central and eastern areas. this area of low pressure will bring wet and windy weather through the course of sunday, and it may start dry and bright. quite chilly across the far north and east across the money, but the wet and windy weather will sweep to all areas. there could be transient snow over the scottish mountains as the rain bumped into the cold air. some will be heavy in places, particularly western hills, and windy across all areas, particularly southern and western coasts, gusts of a0 or maybe 50 mph. with strong winds and rain, particularly across the south, much milder, 11, 12 or maybe 13 degrees, still on the cool side across the far north—east. low pressure sticks around into the start of the new working week. just anchored to the west of the uk. it will push the

milderairat west of the uk. it will push the milder air at northwards across scotla nd milder air at northwards across scotland and the northern isles as well, so a very mild day to come on monday. but it will be another blustery one, lots of isobars on the pressure chart, so windy once again, showery bursts of rain, mainly southern and western areas particularly over the hills, some of them could be heavy. but it will be not a complete wash—out. temperatures in double figures for most. 12—13 again across the cell. it stays unsettled throughout the coming week. they could be another round of rain and gales on thursday, then sunshine and showers, but you could notice it stays mild throughout.

welcome to dateline london the programme that brings together bbc expertise with foreign correspondents reporting back home around the world, on events here with the dateline, london. this week, borisjohnson has, within days, gone from having a fish supper with the european commission president to threatening european fishermen with the british navy if they overstep the mark in the channel. is an abrupt, hard, no—deal brexit really what the people of the uk voted for?

is this what they were promised and how many members of the government really believe that this is best for britain? president macron is being portrayed as the hard man of europe — but with all sides potentially losing if there's isn't a deal, has the eu overplayed its hand? and how is this all being perceived around the world? borisjohnson has reportedly been invited to delhi to be chief guest at india's republic day celebrations in january. nothing confirmed yet and it might just be speculation. in the indian newspapers. but if borisjohnson wants better trade with india, he might want to brush up on his politics. he was caught out embarassingly in the house of commons this week. when asked about a punjabi farmers strike, he replied talking about tensions with pakistan. the look of astonishment on the sikh mp's face who had asked the question was definitely my moment of the week. with me today are marc roche, who writes for the french weekly political and news magazine le point and ashis ray of ray media.
