european leaders have rejected a british government plan for the two sides to agree the terms of britain's status outside the eu — at the same time as negotiating its departure. the president of the european parliament warned britain not to take any unilateral action before it leaves the bloc in 2019. after 44 years together — britain officially started the process of severing its ties with the european union. in a letter notifying the eu of brexit, the british prime minister praised european values and insisted that britain can hold on to its trade benefits with the eu, even after it has left. the ousted south korean president, park geun—hye, has arrived in court for a hearing that will decide whether to approve an arrest warrant against her — over corruption allegations. if the court approves the request, park will be immediately sent to a detention facility. now it's time for click. this week, click is back in india.

we're hitting the road, the rail and the water. there will be dancing... driving in india is an experience. the roads are crammed and the horn is omnipresent and the rules are... well, they're there somewhere, i'm sure. and that's why we will not be doing a story about self driving cars in india any time soon. and despite the fact that it seems

like everybody here owns a car, that's not true. many people choose to travel by train instead. but if you think that is any less intense... think again. yeah, about those rules... mumbai central station is a massive, heaving hub connecting the city to the north and east of india. but if you look closely, you will see something else connecting the commuters to the rest of the world. 116 wireless access points provide free wi—fi to anybody with an indian phone number. it is provided by google which says that about 2.5 tb are being downloaded here every day. and here is the interesting part, this is notjust about this station. along india's railway tracks lie 16,000 kilometres of optical fibre and google is piping internet access down those cables to feed wi—fi

access to 114 other train stations as well. the man overseeing the project is gulzar azad, who i caught up with while he was waiting for a train. if you had to take one place in the country where you wanted tremendous fibre and you had to have reliable power, relatively speaking, power is a challenge across the country, and you had to have the entire country walking through it there is only one place, that is a railway station. can you guarantee that all services on google‘s wi—fi will be treated equally? absolutely. i think the whole motivation for us, if you look at the reason why we did this was to see if we could provide an open internet, completely open with access to the entire web.

the way the web was designed. so, there is a fibre optic network rolling out from train stations like this to the vast rural areas of this enormous country. and david hopped on a train to find out what effect that's having elsewhere in india. it is hard not to be romantic about the railways of india. british colonial rulers laid track for control, shifting resources — mostly out — and prising open markets. now it is about moving people, millions a day. and thanks to optic fibre, data. i took the train tojaipur station to investigate. it has proper broadband and it is free. people are filling their booths.

apart from some controversy, at another station where commuters were using free wi—fi to download hard—core pornography, the provision of high—speed wi—fi has been almost universally praised. 90,000 people pass through jaipur station every day. i use the internet for news and entertainment. mainly for office work. for this studentjournalist it means she can keep tabs on breaking stories. early in the morning, the world changes like... so many things change. i have to come and check. indian stations are full of thriving businesses, feeding off or simply feeding the thousands streaming through them every day.

free wi—fi has been a boon to local businesses here. ashok runs a tea stall on the platform. he makes more money now that his customers can make online payments to him. i use the wi—fi when my ag signal does not catch. when that does not work, i use wi—fi, especially when a customer pays digitally. i need it to confirm i have received the payment. digital payments are worth about 30%—50% of my takings. this is music to the years of people managing the railways of india. a nationalised industry that runs at a loss. they think that high—speed wi—fi could be a good pull for a station like jaipur. they planned to build a huge concourse and attract retail and services business. it mightjust be an earner. as wi—fi expands and it becomes taken for granted then i think people will transfer more

and more of their business. jaipur is a domestic and international tourist hub of high repute. people come out here from all parts of the world. and when you have a huge concourse it becomes an area where you can have shops and entertainment spots. for google, more people online is more people to sell to. india's railway is the country's backbone. its public wi—fi is poised to be at least as far reaching. welcome to the week in tech. it was the week that laptops and other electronic devices larger than cellphones were banned from cabins on us and uk bound flights, leaving from some african and middle eastern countries. a start—up hopes to be able to provide flights from london to paris by electric plane within ten years,

and faster than concorde — supersonic travel between london and new york could be back with flight times of just three hours and 15 minutes after start—up boom supersonic raised $33 million infunding. an app—controlled unstaffed convenience store has opened in shanghai. created by a swedish company, the always—open, never—staffed—by—a human shop requires users to use an app to enter, scan purchases and to pay. a security camera will be watching. nasa has create an origami—inspired robot that can flatten itself to fit into small spaces. the pop—up flat folding explorer robot, or puffer can cope with extremely high temperatures and, finally, if you could do anything in virtual reality, what would it be? well... if your answer was to play a game of catch with an actual ball then you are in luck.

disney research have been examining how the ball‘s path can be tracked, predicted and matched up in its virtual view as it approaches the catcher. 0r... you could just play without the vt headset. you may have noticed by now that the roads here are in india are... well... utter chaos. what is ever more astonishing — consider that so few people own a car here. there are just 32 motor vehicles per 1000 people in india. in the united states, there are 797. but that number is changing and i'll tell you a secret, it is not going down. look at these roads. that is a scary thought. one solution could be to make better use of the cars that are already on the road.

enter 0la cabs, india's biggest taxi hailing app, the uber of india as you will. or as they say prefer to say... uber is the 0la of india. founded back in 2010, three years before uber launched in india, 0la has taken full advantage of their head start. 0la have historically been number one in india but uber has said that that is changing. it looks like the battle for the cab cash in india is onlyjust beginning. these are the head offices in the silicon valley of india, bangalore. this is 0la's employee number one. india is not designed to have a car ownership rate of... not even 10%. what are the specific needs of your customers and drivers? we made an inclusive platform that is notjust about cabs but auto rickshaws, three—wheelers, tuk—tuks that you have, about many other things in india.

supporting buses, bikes, electric rickshaws. an inclusive platform for mobility wher eyou have transport options at different price points for different cases. so that brings an a lot of options for users. 0la say that it is better because it is local and it knows what works in india. they offer things like walk—in centres for drivers and being the first to allow customers to pay by cash. uber is coming into the indian market. how are you different from them? how will you stay ahead? there is a fundamental difference in the way we operate. we believe in what we want and not what we have. in terms of plugging in things have worked well elsewhere. you need to build from the ground up.

it is about the connection that you make, notjust about the transaction. part of that connection is offering centres like this. here, drivers can talk face—to—face with the company, for example when they join the service for training or if they have a problem, an issue with their wages, for example. but 0la does not actually employee any of these people. 0la calls everybody here a partner. in reality, they are self—employed. that means they do not get things like holiday pay and they are responsible for maintaining their car and paying for fuel. the flipside is that drivers can, in theory, set their own schedule and work when they please. it is a controversial system that transport and delivery companies around the world have used to keep costs down. despite this, 0la really, really wants drivers to drive. a lot. so much so that there are carrots if you stay on the road and sticks if you don't.

what india really needs to focus on is to enable mobility for a billion people with the infrastructure we have. we need to leapfrog all sorts of road construction, etc, because it will not take us where we need to go. we need to promote shared mobility, new sustainable options, our government is focusing in a big way on all vehicles being electric by 2020. 0la is one of the most successful start—ups to come out of the education sector in recent years. called indian institutes of technology, or iits, these top—level universities are dotted across india and they are the driving force behind many of india's technology successes. getting into iit is an incredibly

competitive business. only a tiny fraction of applicants get in in any year. but if you do, you get to work in incredible campuses like this. my first appointment is at the olympic—sized swimming pool — although it's not me who's taking a dip. this is matsya, named after the avatar of vishnu — which takes the form of a fish — it's a multipurpose underwater robot that can operate autonomously, without a human controller, to locate sounds, and recognise, grab and manipulate objects. the team tell me it might be used to find flight recorders from crashed aircraft, although they're also pitching it to the military to fire torpedoes. the project is in its fifth year, and the team leader tells me the work is hard, but can be massively wide—ranging. "like a racing car, or a satellite." brilliant!

matsya is one of 100 projects that have been supported by iit bombay‘s society for innovation & entrepreneurship since 200a. sine is an umbrella for start—ups and, as with incubators everywhere, you'll find all kinds of ideas bubbling away behind its doors. as you might expect, there are aerial ideas, there are medical ideas, but there are also musical ideas — which is why you find me making strange noises with my face... doooo—deeee—doooo. .. very good.

you got some score over here. "some score"! if you do it better, your score will increase. yeah, the worst karaoke india has ever heard. but then, this singing—training app is so much more than normal karaoke—style games. most karaoke apps do a very cursory kind of evaluation of your singing. some of them don't even value the singing, theyjust some input — you just open your mouth, you get a good rating. what we do is a multidimensional evaluation of your singing on different aspects of music — pitch, rhythm, falsetto, dynamics, timing... eeeehhhh—oooohhhh... what?! you asked for a hard exercise! eeeehhhh—oooohhhh... eeeeeh—eeeeee—eeeeehhh. .. echo|ng if my singing went right through you, i've got something upstairs that will really cut to the bone. the algosurg team are working

on a system for surgeons to plan surgery. they've created software that's learned to create a three—d model of bones from just two two—dimensional x—rays. i can imagine, after a lot of experience, a bone — if i just look at an x—ray, i can imagine it in three—d. can we do the same thing with computers? a surgeon can do it, because he has learned a lot of correlation between x—ray image and that 3d bone which he sees during the surgery. we used the same logic to develop the software. we have a machine—learned algorithm which has learned the 3d shape of bones across the population. we have created a lot of 3d models from ct scans, and we used this as a kind of database, and we create an algorithm to understand that database in a very particular way to predict a 3d model from an x—ray image. these 3d models also allow for tools and guides to be designed to the patient‘s specific dimensions.

for example, if a surgeon was preparing to cut and realign legs. we have special, specific instrumentation which uses the bone surface in 3d, and it is like a negative of the 3d bone surface. if you make that part and print it in 3d, and put it on the real bone, it will exactly fit in a very unique fashion. so what we do is, we use that concept to cut, to make surgeon cut more accurately, so this part will be exact fit on the bone, but it will also have a slit which will be aligned with the cutting plate. that slit can be used during the surgery to guide a cutting tool. two x—rays are, of course, cheaper than a full 3d ct or mri scan and, once again, it means patients can be assessed who can't get to a fully kitted hospital. there's no surprise that many of the projects here concentrate on low—cost, rugged solutions to developing—world problems.

you may have come across braille displays before, which allow you to connect via bluetooth to your android tablet, then whichever menu item is highlighted on the screen, the text is mirrored on the braille readout here, and you can control the navigation using up and down buttons here. well, this is a prototype braille display called brailleme, which works in a slightly different way. the braille displays currently existing on the market are based on piezo—electric technology. because of that very thing, the cost of these devices are around $2,000 to $3,000 each. we developed a completely new technology based on magnetics through which we are able to reduce the cost 10 times. we can sell it to the user at a price point around $300 to $400. this machine needs to work for at least 10 million cycles of up—and—down movement, it has to be quiet, low power — all of those features make it very difficult to make such a compact device. so that is the challenge. this is the anjuman urdu

primary school in the town of kundapur in karnataka. there are 155 kids here from grades 1 through to 7, and a whole bunch of dedicated teachers. and this is how they start their day. singing. over in vuaya nayak‘s classroom, things are a little more serious. so, at the back of the projector, there's an android device which is plugged in and is running videos on english, maths and science. the videos are made for the entire region. but then they're dubbed

in different dialects, different languages, depending on where they're being sent to. today, we're learning about fractions. it is great teaching tool — as long as there is electricity. but there are plenty of times when there isn't. translation: this is a billet school. 0rdinarily, it would be difficult to teach because of power cuts. we would get electricity in the mornings but, as the day passed by in the afternoon, we would have power cuts for more than two hours. that's why the projector and tablet are hooked up to this box, which is itself attached to a solar panel on the roof. together, they can provide up to five hours of electricity a day, meaning that classes don't have to be interrupted or cancelled if the power cuts out. then, we started using solar power, as it is an easy and natural source of generating electricity. we have introduced a study of generating power through solar energy to our students, and are teaching them the importance and working of it.

we also explain to our students that this process will help us, in the future, to generate electricity. this whole system has been provided by the selco foundation, an indian charity with the aim of helping to alleviate poverty by improving access to energy. with this, students can get a better education through audiovisual teaching, and also there is no problem with electricity. so any time the teachers can take their students to the classroom, they can teach through this medium. selco and other ngos they work with pay for half of the cost of installing the projector and solar system — the other half comes from local schools or local government. how important is the projector? translation: before this project came in to use it, we had very few students. but since we have started using the solar power, our number of students has increased in a good way. we have students coming to us from different villages to learn, and not only students — we have other schools coming down

to our institute for smart classes. the smart class is a good way of teaching kids these days. they seem to enjoy and learn more than usual. after we introduced smart class, our school stands proudly in the educational sector. we plan to grow larger as the years pass by. cool whoa! the same system is already in hundreds of rural schools, and they're aiming to add hundreds more this year. and it's notjust key for schools — across rural india, businesses can be helped massively by having a reliable power supply. somana is a seamstress who lives a short drive from kundapur. she became the main breadwinner for the family after her father was taken ill. the more clothing she can repair, the more she gets paid.

with her old, hand—operated sewing machine, she could fix a couple of items a day. but thanks to the solar panels on her roof, her electric machine can whiz through five or six clothes per day. plus, she has a fan, a tv and a light, so she can work earlier and later. 0ne—quarter of india's rural population lives below the official population line — that's 260 million people whose livelihoods could be improved by the addition of basic facilities like electricity. and of course, one key way of helping people out of poverty is... ..education. it's always such a privilege to come to a place like this and see how the simplest technology can make a world of difference. that's it from india for the moment. you can see plenty of photos and more backstage gossip on twitter — we live at: thanks for watching.

see you soon. hi there. mixed weather fortunes for today's weather picture. some will have the best weather so far. for others it will be cloudy, damp and breezy. western areas will have rain today. rain coming from the south and west. across eastern areas of england, the air has been coming up from the near continent, and that will bring temperatures into the low 20s in the warmest spots. as i say, the warmest day of the year so far.

a mild start to the day for many of us with temperatures staying in double figures, 11 to 12 degrees as we start off. always the risk of pulses of rain affecting northern ireland. western areas of scotland looking pretty wet. and maybe for cumbria as well. and in fact there will be some further pulses of rain across these western areas through the day on and off really through the rest of the day. for the east, after a rather cloudy start to things, things will brighten up with some hazy sunshine coming through. for scotland, south—western areas the warmest. dumfrees and galloway. not too much rain towards the murray coastline. here there could be some brighter spells coming through. northern ireland, rain. there or therabouts for much of the day. but there will be some drier spells from time to time. western england and wales also prone to seeing some pulses of rain even into the afternoon. but further east, that's where we've got the warm sunshine. sunshine will be hazy. we could see temperatures pushing up to 22 degrees in the warmest spots. now, during the evening and overnight, there will be some more wet weather coming across western areas of the uk. the rain turning more persistent and heavier.

there'll be some rather murky conditions developing over the hills as well with mist and fog patches. but it wil be another mild night. temperatures 11—12 degrees for many of us. let's take a look at friday's weather picture. low pressure is in charge. we're going to see a band of rain moving its way north and east through the morning. then the weather will try to improve as we head through the afternoon. northern ireland brightening up. there'll be some sunshine spreading across much of england and wales. southern areas of scotland too by the end of the day. it will turn quite windy for northern scotland later on. never that warm in the far north. but in the sunshine, temperatures pushing well into the teens. pretty mild for the time of year. and for the weekend, it's an unsettled start to things on saturday. a mixture of bright spells and passing showers. temperatures between 12 and 16 degrees celsius. the winds tending to be quite light. showers will stay with you if you are hit by one. showers will be killed off. we will look at a decent kind of day on sunday. sunday, on the cool side. cooling off in the afternoon. perhaps one or two passing showers for the north and west of the uk.

temperatures reaching a high of 17 towards the south—east. and that's your weather. crewmen are the a very warm welcome to bbc news, broadcasting to our viewers in north america and around the globe. my name's tom donkin. our top stories: signed, sealed and delivered — now the hard part begins — britain formally triggers brexit and the prime minister says there's no turning back. europe's message to the uk — we're ready for negotiations but it's not a happy moment. we already miss you. thank you and goodbye. south korea's ousted—president in court — prosecutors are seeking the arrest of park geun—hye over a long—running corruption scandal. leading democrats and republicans in the us senate say they'll work

together to establish any russian interference in the presidential election. and a global football star immortalised in bronze — own goal, or work of art? you decide.
