it's brilliant. and this is the size of the chip that hackers have inside them. would you want one? currently today, i've programmed it to send you a text message. tanja does. she's a tech expert at a university, and believes it is important to be a pioneer human with a chip. this is a very simple chip. the danger is not that great. in the future they could be more versatile, more powerful. we don't know what it can hold. that's what we're trying to explore now. there are only 200 in the uk at the moment with a chip. we think nothing of them in cats and dogs. is putting them in people the next logical step? danny savage, bbc news. time for the weather with matt taylor. wave those magic hands and bring some good news. i will try my best. dry, sunny and warm from any

tomorrow. if you think you have got away with it today, think again. eastern areas have been dry and bright. the showers macro moving from west to east. a soaking in parts of scotland. showers turn heavy, potentially thundery, to what is part of england. in west midlands brightens up. tonight, the showers gradually fade. the rain in northern scotla nd gradually fade. the rain in northern scotland users. things turn dry into the start of sunday morning. it will bea the start of sunday morning. it will be a little bit on the cool side. good sunny spells to begin with. cloudier in northern ireland. patchy rain moving into scotland later. the odd isolated light shower. most places will stay dry. feeling warmer

tomorrow and feeling war going into next week. this is bbc news. the headlines: the us president flies to saudi arabia, but as he leaves there's another twist in the controversial sacking of fbi chiefjames comey. a disagreement within labour over trident, after shadow foreign secretary emily thornberry says the party could abandon its support for the nuclear deterrent. the tories defend their pledge to cut net migration to "tens of thousands" after it comes under fire from former chancellor george osborne. the wedding is taking place of pippa middleton, the sister of the duchess of cambridge. she's marrying financier james matthews in a ceremony in berkshire. thank you for your company over the last few hours. sophie long will be here at the top of the hour.

now on bbc news, sir ben ainslie‘s team will continue their bid to win the 35th america's cup when they race in the final qualifying stages of this year's event next week in bermuda. natalie pirks has been behind the scenes to look at their preparation. sir ben ainslie is the most successful sailor in olympic history. but since the first race in 1851, no british team has ever won the america's cup. personally, i think everyone in this team it would be the biggest achievement if we could pull this off and win the america's cup for britain. it is 166 years to pursue a trophy that we made and challenged the world. and we have never won it. sometimes in life, there is a right time. this is the right time. this is the best chance britain has ever had at winning the america's cup. i think it is a very,

very competitive sport. we have a lot of respect for each other. but we want nothing more than to kill each other on the water. it is as simple as that. if you are silly enough to wind him up to that level where he feels like his back is against the wall, he will respond and the only way he knows how, which is to win on the water. unless you are a kiwi fan, that is a beautiful sight. 2013, san francisco. ben ainslie, a tactician upon the oracle. heading to the finish—line. from 8—1 down, they staged one of the greatest comebacks in sporting history. the americans, beating team new zealand 9—8 in the final. the stars and stripes say it all. the comeback of 2013 is complete.

america's cup will stay in america. it is the oldest trophy in international sport, and one of the rules is that the winner gets to decide where the next america's cup will be held. oracle chose bermuda. i have come to find out why 65 members of land rover bar would move their lives and families to this tiny set of islands in the atlantic. all of it is to chase their skipper‘s dream. come in. i guess you could say the america's cup becomes a life obsession. it is certainly very complex setting up a new team. you need to raise the funding get

the right skill—sets across the board, be it sailing, design, technology, or management, and bring that all together. it does takes time. it takes time to get into a dominant position in the america's cup. is this the bit we aren't allowed to film? actually, we're not allowed to film any of this. no worries. no—one else will see. there is no other sailor in the world with a track record like ben ainslie. ben ainslie is well used to calling the shots, just not as a team principal. he sailed solo at five consecutive olympics, winning medals at each of them, four were gold. you are watching someone who has just become the greatest sailor in history. here, though, ainslie‘s

in an unfamiliar role. his rookie team is the firm underdog. if we went racing tomorrow it would be a bit like turning up to a gunfight with a knife. but i'm pretty confident we might be competitive when it comes down to it. people will be surprised that are right now potentially writing us off. speed is the order of the day in today's boats. but it hasn't always been this way. the boats were graceful, the outfits, impeccable. film reel: look down her steel mast, see the beautiful lines of her hull. when the first challenge was held off the isle of wight in 1951, it was held by a schooner called america, giving the trophy its name. and though many tried,

once the cup left britain that year, it never returned. britannia may rule the waves, but someone forgot to tell the crew of the ranger. fast forward to today, though, and the boats are unrecognisable. the america's cup class boats are built to a strict design role. they can reach speeds of 60 miles an hour, and are powered byjust six sailors. they're the smallest boats in the history of the cup. at just 15 metres long, the wing—sail is 23.5 metres high. but the designers are allowed creativity in their designs. and that's where the fun starts. espionage has long been a big part of the america's cup. teams attempt to gain a competitive edge by spying on their rivals. this year, most of the boats

are powered by hand grinders. but new zealand have opted for pedal power, which could result in greater speed. all of the boats, though, fly on the water on foils, using the same technology as an aircraft wing. just as a wing lifts the aircraft off the ground, the foils of the boat lift the boat off the water. it doesn't always go to plan. racing will take place in a natural harbour called the great sound, and i have come to see how rita, as ainslie names all of his boats, looks out on the water. wow. it is only when you see it close up do you appreciate it.

these are like planes. they glide on the water to be the aim is to not touch the water as much as possible, as it will minimise drag and make them go faster. it is just amazing to watch. this is the formula 1 of sailing. what does that mean? i think in formula 1, it is the pinnacle of motorsport. this is the pinnacle of sailing. formula 1 has the most technologically advanced cars in the world, and the same is said of the america's cup with boats. if you can now call them that, as now, of course, they fly. ceo, martin whitmarsh, knows plenty about formula 1, having been in the sport for 20 years. many others with car engineering knowledge have also been brought into the team.

and a base back in england at the headquarters of the team. it may not have the glamour of the need, but it is a vitally important piece of the puzzle. it is here in portsmouth‘s historic dockyard where rita was built. the designers are all based here. they capture and examine all of the data sent back to them from bermuda to mission control all in a bid to refine the systems of rita. it has taken 85,000 man hours and £110 million to get to this point. personally, are you feeling a lot of pressure? we all do. but it is self generated. everyone here is working late. everyone here is doing their best to think of every idea we can and to deliver those ideas to be needed so that the guys can make the boat faster. the trick is to keep positive. if you let yourself get too much pressure, you will go backwards and make silly decisions.

jimmy spittle could write the book on pressure. the look onjimmy spittle‘s face told the entire story. a skipper of the american team, oracle, sailed with ben ainslie in the last campaign. the team is nowjust one win away from the america's cup. they had to use every ounce of their sailing knowledge to engineer the greatest victory the sport has ever seen. against all the odds, the comeback of the century is complete. from 8—1 down to an eventual 9—8 winners, the sailing press may be dismissing the chances of sir ben ainslie this year, but there is no way spittle will. what i have learned in this game, especially in san francisco, many people said we were taking a knife to the gunfight. most people were saying at 8—1 it was over. then we saw what happened. i think, in sport, the great thing

about sport, is that you never know. i, for one, will not be discounting that team. both of us are very, very competitive. we have a lot of respect for each other. but we want nothing more than to kill each other on the water. it is as simple as that. i think the relationship has changed quite a lot since san francisco for that very reason. you know, when you are a team—mate, it is a certain type of relationship. when you are competitor, it is a certain type of relationship. it doesn't change respect for each other, but it is natural. so you might not be going out for dinnerjust yet. very unlikely. jimmy may not be keen, but the cup organisers are. ben is an incredible talent. their team is packed

with sailing talent. the america's cup needs a strong team from britain. you know, that's created a lot of interest back there. i think sir ben ainslie, if he wins this, he is obviously going to be... . . become even more popular in the uk, and, you know, that's fantastic. he could become a king. king ben, yes! that one might be impossible, even for an olympic legend. but his team are certainly giving it a go. you know, seeing the effort the guys are putting it the gym and being involved with other teams, you can see the actual determination they have. they are doing it for queen and country. it is very special. chasing the dream of becoming the first british team to win

the america's cup doesn'tjust require great sailors. only elite athletes need apply for this most demanding of endeavours. these boats are essentially are powered by the sailors on board. we have no form of stored energy. we don't have an engine. we are the engine. there are four grinders on the boat. there's a helmsman, a wingsman. we produce all the power that is needed to move the foils and essentially get the boat going as fast as possible. the guys who provide that power need to build muscle. the other two roles are more likejockeys. they need to be as light as possible. with an overall weight limit, it is crucial the likes of sir ben ainslie don't sneak chocolate on the side. during the olympics,

my weight was roughly 15 kilos more than i am now. i haven't been this weight since i was about 18 years old so be it has been a bit of a change, a bit of a challenge. but, you know, the physicality of these boats is immense. we obviously take the fitness programmes very seriously. i think the whole team probably dislikes me a little bit for the nutrition we put in place. but, you know, that isjust part of the level of the sport they are operating at. they cannot afford to take on a bad fitness regime, a bad nutrition regime. we spent three years building 20 hours on the water. these guys are doing 35 hours a week of physical exercise. i don't think the athletes have ever had to be this fit. and that fitness has been paying off.

going straight here, going straight. bar won the world series of races that built up to this event. all clear. six teams are contesting the cup this year, not only from britain and america, but also japan, france, new zealand and sweden. go wide! the deck, though, is skewed heavily in favour of the defending champions, in this case the americans, oracle, who are guaranteed a place in the final match. the qualifiers determine who will face them. land rover bar will start with two bonus points for winning the world series. everyone races against everyone twice, scoring one point per win. one team will be eliminated. oracle skipped this part. four teams go into two semifinals

and then a play—off final is held to find out which team will challenge oracle in the first of seven series finale. the winner takes home the oldest trophy in sport. but with just days to go until the qualifiers begin, bar has found real challenges with the design of their boat, compared to most of the others. their straight—line speed is proving to be a real issue and has led to frustration. we have had over 1,000 sensors on the boat, which... every area the designers can see a strain, the stresses, the performance of the boat, and obviously that all gets fed back to team base in portsmouth to get analysed and work out what improvements we can make. and when you see that information, if you're unhappy with something, do you then start shouting?

do you get on the phone? there have been a couple of times where maybe i've voiced my disapproval on a few things... "voiced your disapproval" — shouting? i don't think i've ever shouted yet. he told us that he hasn't shouted yet. is he lying? that's a massive lie! he has shouted at the dog a couple of times. i'll tell you what he does do, he throws his helmet. does he? yeah. the helmet disappears. gojim, go on! go after biggles, go on! lady georgie ainslie is sir ben's wife. a sports presenter in britain, she's moved with their young daughter, their two dogs and the kitchen sink to a rented house in bermuda. good girl! well done! there's a great saying, generally, you've got a happy wife, you've got a happy life and i think that's very true. it's massive, but when you marry a sailor who wants to compete in the america's cup, you sort of sign up for it.

and it is funny and it does amuse me because a lot of wives stress about it and you think, you know what you signed up for! this is the way of our lives. yep, ok. so slightly above ben. georgie has clearly bought wholesale into her husband's dream. no one has a better insight into how he's dealing with being the underdog. he knows there's pressure, he understands the pressure and i don't think there's anyone better to deal with it or cope with it, but if you're silly enough to wind him up to the level where he feels like his back is against the wall, he will respond in the only way he knows how, which is to win on the water. it's interesting, actually, because the mind games have started, the opposition are getting a bit testy, they're pushing all of his buttons, but no one seems to comprehend, despite people having worked with him previously, how he will respond to that and the only way is to go out and win.

everyone else is living in a hotel in the capital, hamilton. such is the attention to detail that the team has started a school for the children. so why are there so many exclamation marks? what page are we looking at? page 1a. can you find page 1a for me, you two? what do you guys do most days after school? go fora swim. iswim. swim! i either go to the pool or i go sailing. i've got a club at sailing now, so i go sailing. wow, so do you want to become a sailor? yeah. do you think one day you might become an american‘s cup sailor? maybe. giles scott shared the same dreams at the same age. 22 years later, he won olympic gold for britain at his first attempt

in the finn class, in rio, the same class of boat that ben ainslie dominated for so many years. the pair were rivals on the water, but great friends off it. now he's also devoted to bringing the cup home. it's one of the greatest sporting trophies. it's certainly the greatest sailing trophy. we realise, as sailors, that we're incredibly fortunate to be involved in a team capable of winning the america's cup and i suppose that's it, it's as simple as that. when you have that much passion for something, working hard, working long days and not getting weekends is the easy part. there's no denying, though, that you need great wealth to pursue this trophy. the owner of oracle is worth a reported $50 billion. criticism that it's too elitist won't be helped by holding it here, one of the most expensive places

on earth, but organisers are trying. a new framework agreement between the teams has been agreed to modernise the sport and bring costs down in future. sir keith mills has been instrumental with helping bar with funding. well, this is the final countdown, where it all comes together. the last two or three years, all of the effort, the money was raising, the sponsorship, all the physical fitness, all the technology. in the next two or three weeks it all comes together in a package which we hope will win the america's cup. he hasn't ploughed in all of this cash for just a trophy, though, he sees it as a long—term investment. and, for him, ainslie is the key. i know he sees what i never see on the water. he takes tactical risks that i never take. he sees gaps in the water

that i never see. but more than anything else, he never, ever gives up and that's the great trait of a great sportsman. sometimes in life there's a right time and this is the right time and this is the best chance britain has ever had at winning the america's cup. we've got the best sailor in the world. will we win it this time? who knows, it's sport. but if we don't win it this time we are certainly very close to winning the america's cup, ithink. from my short time with ben ainslie racing, i've learnt that this is a team that would go into battle with ben any place, any time. the task is great. no team built from scratch has ever won the america's cup at the first attempt. there's a lot of pressure and there always is.

if you throw your hat into the ring of what is the pinnacle of any sport, then you're going to have a tough battle on your hands and we've certainly got that. but within the team it feels like a question of when and not if. i could sit here and say with reasonable confidence that at some point in the next 20 years we will win the america's cup for britain. it may not be this america's cup, but certainly in the near future we'll get thejob done. personally, and i think for everyone in this team, it would be the biggest achievement if we can pull this off and we can win the america's cup for britain. you look at our sporting maritime heritage, it's the one thing that's missing. it would be huge if we can bring the cup home. good afternoon. things are looking
