Good afternoon. The family behind the British Defence company, cobham, has criticised the government for approving a £4 billion take over by an american firm. A merger between the dorset based manufacturer and Us Private Equity Group advent was agreed injuly, but it was delayed over National Security concerns. Late last night, the business secretary, andrea leadsom, who announced the decision late last night, said it had been taken in conjunction with defence chiefs. Lady cobham said the announcement had been cynically timed to avoid scrutiny. Our Business CorrespondentKaty Prescott reports. One of the uks oldest defence companies. A pioneer of air to air refuelling, cobham started life in the 1930s as a flying circus. For the last few months, the government has been grappling with whether to allow its sale to the American Private equity firmed advent. The daughter in law of the founder has been critical. She says this is a deeply disappointing announcement and one cynically timed to avoid scrutiny on the weekend before christmas. Borisjohnson, arriving estonia to greet uk troops earlier today. In the run up to the sale, the ministry of defence said it was concerned about the change of ownership because of giving away access to information and risk to existing programmes. To allay those fears, the government says advent has agreed to. Defence analysts believe the company is already strongly linked to america, a uk ally. Advent have given every protection to the mod, on top of those protections that were already there, so i am not worried about the National Security aspect whatsoever. And secondly, cobham needs to grow. It needs a better base, it needs the opportunities, and i think under a new ownership, it will get them. It wont have to look over its shoulders at shareholders. The government says that the agreement with advent is legally enforceable, and any breach could be pursued through the courts. Katy prescott, bbc news. Our political correspondent, matt cole, is here with me. The Prime Minister has been demonstrating his support for the military today but presumably that could be overshadowed by events back home . Indeed. This was meant to be a fairly standard pre christmas photo shoot. The Prime Minister among the 850 troops at that estonian base. Downing street billed it as a moment to be thankful for our troops and their deployment over christmas particularly but this late night announcement yesterday that cobham was being bought out by advent has raised political questions, not least over security and information held on cobhams systems but the question of manufacturing and potentially jobs under threat. This isa potentially jobs under threat. This is a high end tech that britain will be focused on as we head towards our future trade relations with the world. Speaking in the last few moments, borisjohnson world. Speaking in the last few moments, Boris Johnson has world. Speaking in the last few moments, borisjohnson has had lots of checks have been gone through to make sure of the security of their set. Boris johnson make sure of the security of their set. Borisjohnson also said the uk will continue to be a very dynamic and creative, his words, contributor to this industry. So he, like his business secretary, is playing down concerns over security but i think the questions on this absolutely set to continue. Thank you very much.

Outside the king Edward Hospital in Central London where the prince is staying. Some debate about how he got there yesterday. Any indication of his condition and how long he is expected to remain . There hasnt been any further update from buckingham palace. Not surprising, given they dont tend to give a running commentary for what they say isa running commentary for what they say is a private matter.

He was brought here yesterday on the advice of his doctor at sandringham and it has been reported that he was flown here by helicopter from norfolk to Central London.

With more on that and the rest of the days action, heres holly hamilton at the bbc sport centre. Good afternoon, holly. Good afternoon. Yes, the news came about an hour before everton kicked off their premier league match at home to arsenal. Ancelotti is there, watching from the stands this afternoon as is arsenals new manager, mikel arteta. The appointment of ancelotti is sure to go down well with the everton fans hes a man with an excellent track record, as Michael Redford reports. Triumphs, titles, trophies, Carlo Ancelotti is a man who knows how to get success. Next challenge goodison park. Etherton will be the tenth club hes managed in a career that spans nearly 25 years. His first big success came in 2003, leading ac milan to Champions League glory. There was also cup and League Success as glory. There was also cup and League Success as well. Another Champions League final followed in 2005, although liverpool would famously triumph in istanbul. Two years later, ancelotti had his revenge. The same teams, a different outcome, this time ac milan would rule supreme this time ac milan would rule supreme in europe. Chelsea soon came calling and success soon followed, a premier league title in 2010 became a domestic cup double as they won the fa cup as well. A sacking at sta mford the fa cup as well. A sacking at Stamford Bridge led him to psg. League title one mission completed. Still, angela t was ambitious. Next up still, angela t was ambitious. Next up real madrid and thats the biggest title of all. A tenth european cup for the spanish giants. From madrid to munich and another trophy, league1 from madrid to munich and another trophy, league 1 with ease in 2017, munich finishing 17 points clear. It would prove to be his last triumph, for now. Two years at napoli without any major success. His sacking led him to everton, whose fans may feel christmas has come early. To bring someone christmas has come early. To bring someone of his category is undoubtably excited. Whether it is the right fit or will last long term is another matter but i think right now evertonians, after the season weve had, after disappointments and underperformance, are allowing ourselves to get a bit excited. New era awaits the ancelotti and a new era awaits the ancelotti and a new challenge to keep their side in the top division. But with a cv is impressive as his, few would rule out ancelotti bringing his magic to merseyside. Michael redford, bbc news. Ancelotti hasnt seen his new side score yet. Its goalless so far at goodison park, nearly half time and it is goalless. This weekends premier League Fixture list is missing the leaders, liverpool, who are in doha for the final of the club world cup. The champions of europe will play the champions of south america, flamengo, and our reporter olly foster is there for us olly, liverpool are taking this seriously, arent they .

That is the title that goes with this club world cup. You go back to 1981, they lost to flamengo, the brazilian, south american champions. They still slip leek sing songs about that, thats what it means to theirfans. There about that, thats what it means to their fans. There will be 30 40,000 of them. Not so many liverpool fans but they come in the hope that they can be crowned world champions to go with that european champions title. Rewind to the beginning of the week when liverpool arrive, a mishmash of a team, when liverpool arrive, a mishmash of ateam, a when liverpool arrive, a mishmash of a team, a few injuries, jurgen klopp was honest with us and said, what are we doing here in december . The weather is very nice but this might distract us, might stop our winning momentum. Theyjust got through their semifinal on wednesday night against the mexicans of monterey, an injury time winnerfrom against the mexicans of monterey, an injury time winner from roberto firmino. He relied on their substitutes. They will be, we think, at full strength at this final and he sensed the intensity and passion from the fans of the mexicans. We realised this is a big deal to stop liverpool will give it their all. They say they havent travelled 30,000 milesjust to make up the numbers, but flamengo, the brazilians, are also a very good team. Could be interesting, thank you. And that match is live on bbc one, kick off at 5. 30. Back to you sean. Thank you very much, holly. You can see more on all of todays stories on the bbc news channel. The next news on bbc one is at 3 55 bye for now. Hello this is bbc news. The man who fought off the attacker at fishmongers hall near London Bridge using a narwhal tusk has given a dramatic account of how he was able to stop the knifeman and pin him to the ground. Two people died in the attack last month. Civil servant darryn frost has described how usman khan was running towards people with knives raised above his head, and wearing what looked like a suicide vest. This report from rich preston. This is the dramatic moment passers by attempted to stop convicted terrorist usman khan. His attack had begun at fishmongers hall, where he had just killed two people. It was there darryn frost, a civil servant, took on khan, with others attending a prisoner rehabilitation event. Describing for the first time what happened, mr frost told the press association that he took a narwhal task to defend himself after hearing a commotion from the floor below. He described the moment khan ran at him with knives raised above his head. He went on to recall chasing khan onto London Bridge, where a group wrestled him to the ground, stopping him attacking anyone else, or set off what they thought was a suicide vest. Talking about jack merritt and saskia jones, who were both killed by khan, mr frost said he will always feel the deep hurt of not being able to save them. He said he hoped speaking out would urge people to unite against terrorism and raise money for the victims families. The government has rejected concerns that one of britains biggest defence contractors, cobham, is being bought by an American Private equity firm, advent. Critics say the £4 billion deal is a threat to National Security. Eric grove is a visiting fellow at the International Institute for strategic studies and says its not surprising the government has said this wont be a Security Risk. Well, of course, it is an American Company, and were so closely integrated with the United States, i mean, the f35s carried by our aircraft carriers, in fact, our aircraft carriers will be carrying a Us Marine Corps aircraft as well as raf slash fleet air arm aircraft on the first deployment. So, in fact, having an American Company taking over is not really a tremendous Security Risk because were so integrated anyway, and cobham in fact have more sites in the us than they have in britain. I was going to say, i think, looking at the figures, its 10,000 people employed by cobham around the world, 1700 of them in the uk. I think its main base is dorset in this country. But in terms of the importance of the technology, how significant is the air to air refuelling capacity . Well, very significant indeed. I mean, obviously in Flight Refuelling is an important part of any countrysaviation capability. But on the other hand, we are so dependent on the americans anywhere that i dont really see this makes a huge amount of difference. I mean, we are very heavily integrated already, probably even more so after we leave the eu and so on. So im not too concerned. I can understand why the cobham family are a bit concerned about this, because this was very much a British Initiative and so on, in Flight Refuelling was very much pioneered by alan cobham and so on. But i dont really see this being a great problem. In fact, as i say, we are so integrated with the United States anyway that this is just, you know, an additional. Just a slight change in the balance. Nearly 100 Flood Warnings remain in place in england with further heavy rain expected across the south of the country. The met office says up to 30 millimetres is forecast in some areas and yellow weather warnings are in place. On the final weekend before christmas. Flooding is causing disruption to travel plans for those intending to take the train with lines in parts of sussex submerged. And these pictures of from teston bridge near maidstone in kent this morning show the flooding there. Earlier i spoke to our reporter adrian harms who was just outside guildford, and gave us this update. I am by the river wey, im actuallyjust outside guildford. You can probably see from the pictures that it is raining heavily. Its gone outside guildford on these fields. It is still raining. It looks like the situation will get worse before it gets any better. There is a lot of water making its way along the river. Across the county, how is the picture looking . You still have pretty heavy rain where you are, right . Across the county, how is the picture looking . You still have pretty heavy rain where you are, right . Yes, and there is more rain forecast for the rest of the day and overnight. Two main rivers. There were six Flood Warnings on the river mole. Some of those have been dropped to the lower state of flood alert, but there is still a Flood Warning in leatherhead. The Environment Agency have been working very hard putting up flood defences around the town. Currently they seem to be working. The same has been happening in guildford, there are a number flood defences around the town towards the bottom of guildford, around the cinema, and around towards the depot and Police Station areas of guildford, where flood defences are in place. People will be hoping that with the levels dont go any higher, certainly for the rest of the day, but more rain forecast.
