regional branches of the governing zanu—pf have passed a vote of no confidence in president robert mugabe, following a military takeover on wednesday. they also want his wife grace, who was apparently planning to succeed him, to quit the party. the lebanese prime minister, saad hariri, has left saudi arabia for france on his private plane to meet president macron. he's been in the kingdom since tendering his resignation two weeks ago. in a tweet, mr hariri said it was a lie to say that he had been held by the saudi authorities against his will. the president of the european council, donald tusk, has warned britain's prime minister theresa may that "much more progress" is needed on brexit talks, before discussions can begin on a future trade deal. the irish prime minister leo varadkar also wants a guarantee there'll be no physical border with northern ireland after brexit. in around ten minutes‘ time, it's newswatch. before that, time for this week's click. just across the water

from hong kong, on the chinese mainland, lies a city at the heart of the country's technological revolution. welcome back to shenzhen. this is where stuff gets made. when you think of china's electronic scene, this might be what you think of. more than 70% of the world's mobile phones are manufactured in china. but all that industry is taking its toll on the city. as the buildings go up to accommodate the influx of businesses, the smog has come down to remind everyone of the price you pay for a rapidly expanding industrial economy. the middle—class here is also

consuming more power, as well as demanding something else — good quality home—grown products. and chinese brands are rising to the challenge, with names like zte, xiaomi and huawei even breaking out of china and becoming recognised and desired worldwide. one such brand is oneplus. now, despite only being four years old, it's already turned out a number of phones that have been compared favourably to the top end samsungs and iphones and this week it unveiled a brand—new handset, the st, with all the fanfare that a big phone launch gets these days. are you all excited? the secrecy that surrounds these new phones‘ prelaunch is intense and, let's be honest, it's part of the hype. look, it's another black rectangle! but as such it's really rare to get

a look behind the scenes at the design, the manufacture and the launch of a new device. but in shenzhen, two weeks before the unveiling, we were given exclusive access to the inner workings of the production line on the run—up to d—day. now i'm qualified to serve you pastries. they make loads of different types of phones in this factory, so to keep the st as secret from all the other workers, everything happens behind the blue shroud of secrecy. are you ready? thank you. come in. welcome to production line 27. the phone starts life as just a tiny camera there and then it's gradually assembled around this u shaped production line, which means by the time it gets to the end it's a fully featured phone, just about there. this is the reason china has come to

dominate electronics manufacturing. a ready supply of a disciplined, relatively low—cost workforce. each person here has one uniquejob which requires concentration, speed and precision. a single speck of dust caught in the camera lens and the finish phone will be rejected. what i found most surprising about this is it's all people. i would have thought with this kind of high precision job, these phones would have been built solely by machines, but it's pretty much all humans. each line can produce more than 90 phones an hour. it's exhausting just watching this. fortunately, the staff get a two—hour lunch break and also, suddenly at 3pm... bell rings this might look weird,

but having seen how intense this job is and how much concentration you need, this ten minute eye break is invaluable. i think if i was doing thisjob i'd just want ten minutes to get my head down and close my eyes and reset my brain too. wow! now, these people are bringing to life a design that has been anguished over, squeezed for efficiency and ultimately compromised to keep costs down. i'm meeting with one of the designers to get the inside track on how he's made this black rectangle ever so slightly different from all the others. for every new phone, you come up with lots of different designs, like this. 200. oh, my word! do you think we've achieved peak design now? in the end, these are all physics. we are still making some choices, some sacrifices, in favour of the beauty of the exterior,

still a little bit. such as? well, such as, actually the best place for this would be leaning directly on the corner. in our design, we have this angle here, so that doesn't allow us to put this directly here. if you could get rid of one part of the phone, back at the factory, simon would be horrified by what happens to his design. dramatic screaming this is where an unlucky few phones are pulled off the production line to check extreme tolerance. elsewhere, other test phones escape that big plunge, but instead are dropped 5,000 times each. others have their charging ports wiggled and buttons pressed 10,000 times. and then there's the tumble dryer. only when about 70% of the sample phones start surviving this vigorous testing will a build be deemed successful. for me this is a fascinating look at how a phone is born and now that

it's being launched this small preproduction line can expand, once the company has an indication of how many orders it will get. and that's the secret. not to produce more than you can sell. so when 0neplus decided to take on the big brands, which can all afford to fail, it decided to sell its first phone by invitation only. what was the thinking behind that? ‘cause i would have tried to make it as available as possible. so being a brand—new company and not making such a complicated product as a smartphone and being based here, we didn't really have the opportunity to test the product in all the countries where we sold it and adding to that we didn't know how many phones to make. if you end up having too many phones in your warehouse that you can't sell, it's over. with the launch over, 0neplus will nervously await the first reviews and, more importantly, the advance orders. and they will decide whether these people will be joined by hundreds

more or not. the uk's anti—bullying week is now coming to an end, but behind closed doors, computer screens and even smart phones, the bullying that some encounter in the school playground still lives on after—hours. after i did come out, i then received online anonymous messages from an account set up to message me, telling me i should kill myself, because obviously they didn't agree with my sexuality. it destroyed me because not only was the bullying happening at school, it had followed me to my home. it followed me to my room,

my safe space where i feel happy and i am myself, isuddenly couldn't be any more. thomas moved schools and went on to become one of facebook‘s anti—bullying ambassadors, a scheme funded by the social network to train up pupils to provide peer—to—peer support within secondary schools. it's really important to have someone there because it's someone they know they can come to as well. and with the ambassadors being their generation, children are more likely to come to us and know that they're there for them. because we are their age, we have similar interests so they can come to us much easier. but with so many different places to communicate, the problem is hard to police, hard to monitor and hard to solve, as those at the frontline of dealing with cyber bullying attest. 0ur concern is just how awful the things are that people write.

it's very sad, but we do regularly see those sorts of comments about "everybody hates you, go kill yourself". those sorts of things, which i can't imagine would happen in a face—to—face environment. as the big and small players try to overcome the issue, one british company has big ambitions. they want to get their software on every single child's device before they use it for the first time. safetonet don't like to refer to their software as parental control because they feel that could put people off. some of the functions, though, could be considered that. for example, monitoring the amount of time that your children are online and limiting that however you see fit. you can block devices and websites, but it also is planning on upping the game of what these sorts of products can do by adding a bit of artificial intelligence. by later this year, it's going to be aiming to track the behavioural changes, so they can pre—empt any bullying before it actually happens. it aims to understand context,

providing triggered alerts for parents, rather than letting them actually spy. one of the ways that we identify when children are trending sad and maybe even depressed is they stop posting selfies of themselves because they've lost that self—confidence. so our software is designed to be able to pick up those trends and recognised, again, there's a change in behavioural patterns. so we are identifying cyber bullying, abuse, aggression, sextortion, grooming and other predatory risks. great if it works, but of course it's all really about human behaviour. culturally we obviously do have an issue that young people believe that you can behave this way online. we need to send a clear message, you don't, and i think it takes all of us to work together, educators, parents and tech companies, to make sure children understand that. so whilst none of the solutions may be foolproof, maybe these ideas together could make cyber bullying

a lesser problem in the future than it is today. that is it for the shortcut of click in china this week. the full—length version is on the iplayer right now. i promise we will be back in this fascinating country very, very soon. in the meantime you can check us out on social media. thank you for watching, and we will see you soon. now it's time for newswatch. halfway to brexit, so how is the bbc‘s coverage doing? biased, baffling and boring, say viewers. we asked how to inform viewers on this most divisive issue. first, events in zimbabwe which first came to the attention of news desks on tuesday evening. it has been taking a while to work out what exact has happened, whether it was a military coup or not.

the confusion was not helped by the bbc quoting as a source a fake twitter account in the name of the ruling party, zanu—pf. 0n radio, bbc one television, breaking news alert and the website. it is not clear who runs the account which referred to an elderly man who had been taken advantage of by his wife being detained in a bloodless transition. some people were unimpressed. brian silvester tweeted: bbc world news later apologised and a spokesperson said: on wednesday, borisjohnson met richard ratcliffe, whose wife is in prison in iran, and that prompted the dimensions mentions on the bbc the foreign secretary's incorrect

statement last week that she had been working in the country training journalists. she was on holiday. on sunday, andrew marr followed up on the comment by asking michael gove about nazanin zaghari—ratcliffe. what was she doing when she went to iran? i don't know. one of the things i want to stress, there is no reason why nazanin zaghari—ratcliffe should be in prison in iran as far as any of us know. you say you don't know what she was doing, her husband is clear she was on holiday. i take her husband's assurance. he said she was training journalists, that has been grabbed by the iranian judicially to put her plight into an even worse position. that is surely his fault. whatever we as democrats choose to do or say, extremists will choose to deploy for their own purposes. we play their game.
