to her brexit deal with the eu. mrs may has won the support of some of her key brexiteer ministers, but she has had to defend herself against further calls from critics to stand down. donald trump says he has personally finished writing his answers to questions posed by the mueller inquiry into russian interference in the 2016 us presidential election. mr trump said he had not yet submitted the responses because he'd been very busy. he again described the investigation as a witch hunt. the white house has agreed temporarily to allow the cnn journalist, jim acosta, back into press briefings, after a court ordered it to do so. the journalist's pass was revoked last week after he argued with president trump during a news conference. is the latest headlines —— those are the latest headlines. in about a quarter of an hour, here on bbc news, we'll have newswatch. but first, here's click. here on click, we are constantly

coming across jawdropping medical marvels. from robo—nurses, to ai which can outdiagnose experts. we have seen the future of medicine evolving before our eyes. it is fair to say medicine has come a long way. this is the old operating theatre museum in london. of course there is an old operating theatre museum, why wouldn't there be? back in the late 1800s for example, this was the cutting edge — literally.

and in the 130 years since, surgery has changed beyond recognition. but, as with all technology, we mustn't become overreliant on it. we mustn't think that it will do everything and we mustn't think that it will work every time. last week, we were given a sombre reminder of this when an inquest found that a cardiac patient, stephen petit, had died as a result of undergoing pioneering heart surgery using a da vinci robot. had the surgery had been of the traditional kind, he almost certainly would have survived. i if a surgeon is going to use a robot, and use is the right technical term, he has to be very well practised with it. i think that was an example where the team were not sufficiently trained or prepared to do that operation. and therefore, it was a very, very, very long

operation that ultimately went badly. we reached out to intuitive surgical, the company behind the robot used in stephen petit‘s operation. they provided a statement expressing their condolences to his family and reiterating that patient safety is their priority. but they said they don't provide and can't enforce a mandatory medical training regime before a surgeon uses their robotic system. this training and validation remains with hospitals. they say that more than 5 million da vinci robot procedures have been performed by more than 40,000 trained surgeons worldwide. so, where now for robotic surgery? well, paul carter has been to see one robo—manufacturers centre of operations, as well as getting an inside look at real—life surgery. at london's royal marsden hospital, we have been allowed to see the surgical robots in action.

following the death of stephen petit, it was interesting to find out more about how surgeons are trained in vr and how they overcome the sense of touch they would have if they were using their hands. before anyone goes anywhere near a patient they are expected to do a good deal of training on that system in virtual reality beforehand. yes, you lose the tactile feedback but you have got very clear imaging and you can very clearly and precisely define your dissection. in this procedure, robotic technology will be used to remove a cancerous tumour in the patient‘s stomach, with fluorescent dye used to light up the area. during the procedure, surgeon miles smith, assisted by assif chowdry, controls three robotic arms which he manipulates to remove the tumour. the aim is to greatly reduce surgical trauma as the robot method is far less invasive than more

laparoscopic traditional surgeries. the da vinci robot makes it possible for surgeons to operate deep inside the body through microscopic incisions. can you keep your voice down a little bit because this is quite a critical part of the operation and what is actually happening behind me is that they are putting in ports into the patient‘s stomach where the robot will dock onto in order to perform the actual operation a little bit later on. the robotic console actually uses keyhole surgery, whereby instruments into the patient‘s body through small holes instead of large cuts. that means less blood loss, less trauma and also quicker recoveries. the robot has four arms, three of which carry tiny surgical instruments and one of which sports a camera. ports need to be put in place before the robot can be wheeled in to dock its arms. what is remarkable about this system is it is generally remote. you can see the arms moving behind me and they almost look like they are moving independently, they are actually being controlled by miles,

who is sat at a console several feet away from the patient. the remote consoles provide the surgeon with 3d visualisations and magnified images allowing complex dissection or reconstruction. the surgeon controls the arms through finger loops that mimic the hands natural movement. so the tumour has just been cut off, for lack of a better phrase. it is just extraordinary, put in a little tool and bagged it up. yes, that's it. let's take it out of the ports. intuitive surgery, who make the system used at the royal marsden, have almost complete market dominance. but now, new robotic surgery players are starting to emerge. we've come to california to visit alaris health, who are developing robotics for a different type of surgical procedure. alaris' monkier platform concentrates on endoscopy,

a procedure which allows treatments to be given to organs through natural openings, such as the mouth, meaning no incisions are required. it can manourvre through a patient‘s airways, even into the far and narrow parts of the lungs, and combined with ct scans, it can provide a gps map of the patient‘s internal organs, allowing surgeons to navigate precisely on areas of concern. i am using what is essentially a modified games controller to operate this scope here. and i am no surgeon, i have been using this for a couple of bits and i am able to make quite precise movements. it's pretty extraordinary. it's clear that robotics finding different surgical niches is one area of growth, but what else does the future hold for surgical robotics? there's no reason why in the future we shouldn't be able to train robots to differentiate between structures that we want to preserve and structures that we want to remove. perhaps a bit like driverless cars, but in this case

a surgeonless robot. possibly under the control of the surgeon. next we're going to talk golf — a stubbornly traditional sport, but one which is ready to embrace the newest technology, as lara lewington has been finding out. this is wentworth club, which in just a few years is going to be celebrating its centenary. but over that 100 years, a lot has changed. in recent times, much of that has come down to technology. so we are going to go and see how both amateurs and professionals in the making good use of that. lasers, radars, sensors, and motion capture have transformed data collection.

and analysing these statistics means training and play can be more precise than ever before. and who better to show us in one of the greatest golfers on the planet? francesco molinari, fresh from wins this year in both the ryder cup and the open championship. one of the difficulties of golf is that there are so many elements, and even so many parts of the body moving through the swing, that any little difference, any little difference makes a change. those tiny differences are captured by the kind of tech usually reserved for big budget hollywood films. 27 reflective markers over his body helped to create a digital double francesco's swing to be analysed in detail. this will pick up endless, endless parameters, in terms 0ptical motion capture analysis uses high—speed cameras to capture every movement in the body and club. this provides francesco's team with data that would have been impossible to measure a few years ago. this is trackman.

the radar basically picks up all the data surrounding the golf course, surrounding the golf club. it picks out points of that will stop and that gives us the data that we can see. so we have ball speed, we've got launch angles, we know how high the ball launched out of the golf club. 15 years ago he would have been in the field watching the ball, whereas now we can physically see. slightly intimidating being this close, but i guess he does know how to hit the ball the right way. the technology tracks the distance, power, and trajectory of the ball, using a combination of hd cameras and a doppler radar. it also registers microwave transissions that move away from a golf club and ball. it is a crucial measuring tool.

0therwise, if you think about it, old school, you would hit all five balls and go look at them and measure them and write them all out. that's the only way that you are going to learn — to have immediate feedback — and this is sensational for that. but is this in some ways ruining the game? before it was a lot of guessing going on, and really going on the feel of the players, and ourfeel. there is now just a lot more feedback. these people with lasers zapping our ball after every shot so we know exactly how far we hit every shot, how far off—line, how farfrom the flag. so far, it has been impossible to track everything, but with the technology you've seen today, we're getting closer and to getting exactly an idea of what is going on. definitely technology has been a massive help in tracking every bully getting immediate feedback, so i would would not be as good a player, for sure, without that knowledge. and that may well be true.

but ultimately the player has to be skilled enough to act on the data that is being recorded, and, of course, this is not there to turn just anyone into a star player. and that is it for the shortcut click this week, the full—length is available to watch right now on iplayer. to forget, we are all across social media, youtube, instagram, facebook and twitter. all you need to say is click and we will see you there. thank you for watching. sometimes being in the driver seat is... she's dead in school, she is

a... this isn't a spaceport, this is... the simple act of standing, and you are... . you don't need superpowers to change the world. 100 women, a series of inspiring and challenging screws across the bbc. hello and welcome to newswatch with me, samira ahmed. no shortage of drama in this week's news coverage, but has there been more speculation than fact? after andrew neil deletes a controversial tweet about a female journalist, has the bbc got a problem with its presenters on social media? first, a week of high drama in westminster began with a challenge forjournalists. it was clear that something important was about to happen, but no one quite knew what that was.

this was how political correspondent chris mason responded on monday morning's breakfast. so, where are we in this brexit process? people like me are paid to have insight and foresight and hindsight about these things and be able to project where we are going to go. to be quite honest, looking at things right now, i don't have the foggiest idea what will happen in the coming weeks. will the prime minister get a deal with the eu? i don't know. will she get it through the commons? i don't know about that either. you might as well get mr blobby back on to offer his analysis because i think his will probably be as good as mine. don't do yourself down, chris mason! was that an embarrassing admission of defeat or a welcome outbreak of honesty? it may have been pseudo—analysis, but in the absence of mr blobby, bbcjournalists over the next couple of days queued up to offer their versions of what was going on inside the brexit negotiations and inside government

and what would happen next. for nick porter, much of this was not news. i was watching the six 0'clock news on tuesday and became concerned when, in response to rumours about the deal on brexit, the bbc decided it was justified in spending almost ten minutes on the subject, using more than one reporter and interviewing several people, but what they were discussing was all speculation. at that point, no hard factual information was available. the bbc‘s mission statement from its website is to "inform, educate and entertain". on this occasion, the bbc has failed miserably on all three points.
