government over access to federal contracts. the announcement comes as the company's chief financial officer, meng wanzhou, appeared at a canadian court to fight extradition to the united states. the american singer r kelly is back in custody after a court hearing in chicago on unpaid child support. officials said the singer would be detained until he paid more than $160,000 that were owed. and this video is trending on bbc.com. scotland's first minister nicola sturgeon got quite the surprise today after baby grace threw—up on her during a visit to a local hospital. she saw the funny side though — joking that there are many people who would love to do the same. that's all. stay with bbc news. a muslim convert has been given a life sentence for planning to kill dozens of people in central london.

lewis ludlow, who's 27 and from kent, was described by his own lawyer as naive and vulnerable. lewis, who called himself ‘the eagle‘ and ‘the ghost‘, swore allegiance to the islamic state group, and had identified oxford street as an ideal target. he had previously admitted his guilt, at the old bailey, to plotting an attack in the uk, as our home affairs correspondent daniel sandford reports. i am the eagle and i pledge allegiance to dawlatul islam. the moment when white convert lewis ludlow swore loyalty to the islamic state group. we love death as much as you love life. i have nothing for this country. together with his islamic state accomplice in the philippines, this man, eyadzhemar abdusalam, he was planning to kill up to 100 people in central london. it was the end of a ten—year journey of radicalisation for the awkward young man. he's seen here with anjem choudary, who played a big role in drawing him into extremism.

i used to be a fascist, a proper fascist. i mean, i used to be a holocaust denier as well. in this video he made, aged 19, he described his path from neo—nazism to radical islamism. counterterrorism detectives had watched him for years. he'd been through the government's de—radicalisation programme but nothing worked. last february, police stopped him going to the philippines where his is contact was based. then he was spotted by an undercover team taking pictures in central london. he is a man who has gone from spending the vast majority of his time in his bedroom at home online to somebody who is travelling into london, taking photographs of iconic locations. that started to get the hairs on the back of our necks standing up. counterterrorism detectives found the pictures he had taken on his reconnaissance trip on a phone he had dumped in a storm

drain, including this picture taken outside the flagship disney store. police also recovered a chilling handwritten note ludlow had made. in it he proposed using a truck, perhaps with a home—made bomb on to ram into pedestrians here on oxford street. he said that way, nearly 100 people could be killed. he listed other potential attack sites too, including madame tussauds and st paul's cathedral. but his is contact was using encrypted messaging to team him up with someone who turned out to be an undercover police officer and ludlow was arrested. at first he denied everything. but then police showed him the video they'd recovered of his oath of allegiance to the islamic state group. we love death as much as you love life. he is now starting a life sentence of which he will serve a minimum of 15 years in prison.

daniel sandford, bbc news, central london. now on bbc news — click. this week: bending the rules, breaking the rules, and cleaning up the mess. it's that time of year again. we head on our annual pilgrimage to the world's biggest mobile event, mobile world congress in barcelona. the stands are filled with an array of gleaming rectangles. but on the whole, they look quite similar — on first glance at least.

well, there are plenty of great phones here, but mine does a lot already. so, would i really want to upgrade just for a slightly bigger screen and a slightly better camera? well, probably not. and it seems that plenty of other people are in agreement with me. two of the biggest brands, both apple and samsung, have seen sales slow down. but where there has been innovation, like 56 or foldable screens, the prices are eye—watering. huawei showed off its mate 10, which has an 8—inch amoled display. when we saw the device fold, it was a wow moment. the screen is thinner than rival samsung's, as the company proudly pointed out, most of the components live to the side. with no release date yet, it did feel very much like a concept phone, though. we were told to keep our mitts off,

but on a brief moment of holding, it did feel a little weighty. but if you're loving the idea of getting that extra real estate on your phone but you don't want to indulge in buying a full foldable, well, lg have a dual display. although it will initially be sold as one package, it's actually a phone case that has a second screen as part of it, allowing you to maybe play a game with a separate control pad or simply message a friend your location with two apps open. but if you don't want to fork out thousands on your device, then this is what's happening elsewhere. as always, camera functionality is where everybody is trying to make a splash. so the back of the devices are adorned with an increasing number of lenses. the nokia 9 pureview really went for it, though, with five cameras —

two colour and three at monochrome lenses — all working in unison to capture an image so the focus can be changed after the fact. some devices attempt to do this with the help of a depth camera, but the results are less precise. and it's been all about minimising the notch, that black bit at the top, to provide an unobstructed screen, samsung and huawei upped the ante by introducing the discreet punch—hole, which other manufacturers will no doubt follow soon. another illustration of how hard it is for big players to stay ahead of rivals like 0neplus. this is their latest model, and it looks and feels pretty much like one of the high—end phones. it has facial recognition, almost an edge—to—edge screen, and it has a fingerprint sensor built in to the screen. but this uses an optical sensor instead of the more premium

ultrasound sensor found in the galaxy s10. and more chinese brands are expanding into the west. xiaomi started selling its handsets last year. and 0ppo showed off its latest high—end device. i do believe this is what you have been waiting for — 0ppo‘s first 5g smartphone. as the market gets more crowded with similar looking phones, the battle to cram in more functionality continues. the second iteration of microsoft's hololens created quite a stir here. it's lighter than the original hololens, but at the same time, it sort of feels more solid.

let's see what the experience is like. there we go. after a brief set—up, i found myself working in construction — albeit of the mixed reality variety. the upgrades include an improved display, doubling the viewing range, adding voice control, and more precise hand gestures. they allow you to stretch, rotate, and move what is in the virtual world, or as was demonstrated at the launch, do something as detailed as play the piano. or i can play the keys one at a time. the field of view is wider, but the experience is definitely better when i'm standing further back, which, initially, when i was trying to move things on the table, that wasn't ideal because i was having to go forward. but right now, i can move the timescale just here to take

a look at how the building work was going at each point. 0k. that's pretty cool. this still isn't a consumer product, though, it's squarely aimed at professionals, with a price tag to match of $3,500. so all the demos are of this nature. well, whilst it's easy to get caught up and trying to get the knack of the gestures, the visuals are actually quite amazing. microsoft wouldn't say if its future plans include a less pricey consumer version, but speculation was rife amongst the crowd that hololens 3 could find its way into our homes. hello and welcome to the week in tech. it was the week that facebook took down the page of anti—islamic activist tommy robinson for violating its policies on hate speech. it also removed his instagram profile

and said he would not be allowed back on the platforms. elon musk‘s tweets landed him in hot water — again. regulators in the us have asked a judge to find him in contempt of court after they said he breached an agreement from last year to have his tesla—related tweets vetted in advance. and the bbc and itv have announced plans to launch a new subscription—based streaming service. called britbox, it will contain archive content for both broadcasters, as well as original commissions. it was also the week that two companies unveiled just what we need — new military drones! yay! weapons maker kalashnikov announced a new kamikaze drone that explodes on impact. meanwhile, boeing announced it's developed a newjet plane sized uav codenamed loyal wingman, which i'm sure is intended to be reassuring. fedex is the latest firm to trial a new autonomous delivery robot. based on technology from powered wheelchairs for disabled people, the delivery company claim that the sameday bot can navigate on paved surfaces,

kerbs and even steps. no word as yet, though, on its capacity for "sorry we missed you" cards. and, finally, do you have trouble sleeping? have you always craved a robot pillow that breathes like a baby? then you're in luck. dutch engineers have created something to fill this particular niche in the market. somnox weighs as much as a cat. it also plays music and aims to calm your breathing. sweet dreams. away from the show floor, this week, nick kwek has been talking rubbish, but at least he went to sunny dubai to do so. dubai, the persian gulf. year—round sun, scorching temperatures. er. ..ot exactly the weather i was hoping for. a bit of winter sun, they said. ah, well, despite being soaked to the core, the show must go on. in these unsuspecting waters lingers a cunning creature —

a wide—jawed wading guzzler on the hunt. meet the wasteshark. this aqua drone sails around marinas and coastlines scouring the surface for plastic waste, debris, seaweed and other pollution. and it's off, setting sail on a mission to gobble up as much garbage as possible. it essentially works like a giant roomba vacuum, hoovering up floating rubbish in its path. the wasteshark is the world's first autonomous marine waste and data collection vessel. 80% of waste that reaches the marinas, the marine environment and the ocean is from the land. so we need to approach the issue of marine protection and ocean sustainability

from multiple angles. so this trash sucker is designed to patrol marina waterways for up to 16 hours before the battery inside requires recharging. it's actually designed up to the whale shark. its big mouth being able to suck up 200 litres of trash at one time. its black plastic zip tie teeth keep bits and bobs inside its mouth, handy when needing to reverse. three independent thrusters control the sharks direction and speed. this current model is actually being remote—controlled by its captain on the pier, but other models have lidar sensors on them, allowing them to autonomously navigate waters. they also have a collision avoidance system aboard too so they can detect nearby objects and, if necessary, move out of the way.

there are big trash skimmers that are very expensive to buy, to operate, they use fossil fuels, they don't reach into hard—to—reach places. it's not the only waste eater that's cleaning up waterways. over in the us, the baltimore—based mr trash wheel sucks in and processes heaps of rubbish. so far, it's cleared well over 500 metric tons of the stuff. and in chicago, the inventively named trash robot is another remote—controlled robot tackling pollution. designed by dutch partner ranmarine, the wasteshark is just one of the solutions being used by ecocoast to improve dubai's waters. the company has also deployed bubble curtains to prevent silt and other contaminants left over from construction reaching the ocean, a real problem due to dubai's ever evolving landscape. the bubbles behave like a barrier,

restricting the movement of floating
