three, two, one... grieving together — an improvised memorial for a tragedy as shocking as it was unexpected to mark the deaths of three teenagers struck by a speeding car in hayes in middlesex yesterday evening. two of those who died have been identified as harry rice, on the left, and george wilkinson. the identity of the third teenager, named locally as josh, has not been confirmed. two were 16, the other 17. jake webb was one of the first on the scene immediately after it happened. i saw the incident in front of me. there was a bus driver in front of us and he came over and said, "yes, there's someone dead in the road" and at that point i relayed that to 999 and within five minutes an ambulance arrived. the three friends were walking on the other side of

the road to a party less than half a mile away. as they reached the bus stop, the car mounted the curb and hit them. the car, a black audi, then smacked into a lampost before coming to a halt in the road, this image showing the force of the impact. eyewitnesses say afterwards a man who was in the car was attacked on a nearby garage forecourt. some locals say speeding cars on this stretch of road is nothing new. it's a 60mph road. and cars, vehicles, drive up here sometimes like it's a speed track. this road's busy 24—7 and if i'm honest, i'm surprised there hasn't been more accidents along it. police believe two men were in the crashed car, and with many other teenagers heading to the same party, they‘ re appealing for any witnesses to contact them. ben ando, bbc news, hayes. and we'll find out how this story, and many others, are covered in tomorrow's front pages at 1030 and 1130 this evening in the papers.

0ur guestsjoining me tonight are nigel nelson, who's the political editor of the sunday mirror and sunday people, and the broadcaster and journalist, penny smith. all current rape and serious sexual assault cases in england and wales are to be reviewed, following the collapse of several recent trials. the director of public prosecutions alison saunders said it was "a matter of urgency" to make sure evidence has been properly disclosed. but the government's chief legal adviser says there's no evidence of "widespread malpractice or dishonesty" in the prosecution system. clive coleman reports. disclosure of evidence in some recent highly publicised rape cases has gone badly wrong. but how widespread is the problem? in december liam allan's trial for rape and sexual assault collapsed. when it emerged evidence on a computer disk, which police had examined, showed messages from the alleged victim pestering him for casual sex.

and the number of prosecutions in england and wales that collapsed because of a failure by police or prosecutors to disclose evidence has increased by 70% in the last two years. now, the director of public prosecutions, alison saunders, has ordered an urgent review of all rape and serious sexual assault cases, and conceded it's likely a number will be dropped. one of the major problems is the amount of digital evidence on phones and social media. it's very apparent that in some cases mistakes have been made that simply shouldn't have been. it is important that when you look at that kind of case that the prosecutors and investigators look at social media traffic, look at text messages that have passed between the two individuals, because they can put what's happened in a very significant, different light. a national disclosure improvement plan has been published. it includes a review of disclosure training, developing a group of specialists

in every police force, and all multimedia evidence to be provided to the defence digitally. yesterday, here, a people—trafficking case — not a rape or sexual assault trial — collapsed because prosecutors failed to disclose critical evidence to the defence. thejudge has demanded an urgent explanation in a case made even more shocking by the fact that one of the young female defendants was held in prison for 13 months, during which time she gave birth. this problem is systemic and endemic throughout the criminaljustice system. it's been known about for many years and it's a result of chronic underfunding of the police, the prosecution service and particularly defence lawyers who have suffered years of cuts to legal aid. if public confidence in our fair trial system is to be maintained, fixing disclosure is now the criminal justice system's biggest challenge. clive coleman, bbc news. earlier i spoke to former cps chief

prosecutor nazir afzal and asked him how concerned people should be about these developments. public confidence has been shaken by a series of cases where very basic things such as disclosure... the most basic thing is providing the defence with a case against them and also the evidence you have that may assist them. the fact it has not been happening in these very high profile cases, and the one that clive mentioned yesterday, suggests to me that something is amiss and it needs to be remedied. we have heard the dpp say she wants every single case in the system to be looked at afresh by a more senior lawyer. the question clive asked, that i asked, as well, is what about other cases? it doesn't have to be just rape and sexual offences. disclosure impacts on all serious cases, everything.

there is no current proposal to look at all such matters. we've got a situation where juries hear the evidence. they don't know now whether it is all the evidence. they don't know what's happening. and i think, as one of your contributors said, the issue is resources. it's not just money. it's experience. a substantial number of experienced police officers have left the service, and there is less supervision now. and so cases are being prepared not as well as they could be. it meansjustice is not being done all the time. when we hear the phrase "failed to disclose", are they saying that teams were aware that the evidence was there and theyjust didn't bring it forward, or they hadn't got to it yet? there is a lot of confusion, here. a bit of both. the disclosure regime is more than 20 years old but social media and the internet isn't.

so they are trying to catch up with where the technology is. in some cases you have to remember that prosecutors don't find the evidence themselves. it comes from the police. if the police have not provided them... they don't know what's out there, they don't know what's available. there is a significant issue with policing and the need for specialist officers to take responsibility for disclosure in the same way they do for the investigation itself. secondly, the prosecutor should be asking questions. the examples we have had recently, was there anything on her phone, or online? was it asked, was it answered? clearly it wasn't answered. that evidence turned up very late. we can't have a situation where a team doesn't work as a team and the experience doesn't seem to be there. as a result, justice isn't being done. and what about other cases? those cases that have been dealt with. what about the rape finalised last week, for example? are you going to look at the evidence in relation to that? this literally opens a can of worms

when you say you want to look at all current cases. because lawyers and defendants will be asking, what about my case a year ago? what about the case you have not prepared that isn't rape or sexual offences? you say something is amiss and it needs to be remedied. are the police, who are in charge of collecting evidence like this, are they equipped to do it? we know there is a problem with resources. are they equipped to do this? you have special cyber teams within the police and they know how to deal with that, but what about when it comes to police officers dealing with sexual assaults? technically, only specialist officers should be dealing with sexual offences. but some are relatively new. some may not necessarily have the contacts within the telecommunications industry or the internet industry which enables them to get that information. but these are basic questions which have to be asked by them. in order to collect it in the first

place. again, prosecutors need to ask the same questions. technology is there. the expertise is there. but the supervision is poor. the experience levels are poor. as a result we are not getting the service from them, the prosecutors are not getting the service from them they deserve. prosecutors, as diligent as they are, they don't know what they have got and they don't know what they haven't got. a bomb in the afghan capital kabul has left 95 people dead and more than 160 injured. the taliban say they carried out the attack. an emergency vehicle, packed with explosives, was blown up at a checkpoint. from kabul, zia shahreyar reports. an ambulance packed with explosives, driven into crowds on their way to work. the force of the blast shook the windows of buildings at least a mile away. some low rise structures collapse.

a plume of smoke visible across the city. the attacker had driven his vehicle past the police checkpoint, claiming to have a patient inside. when guards at a second checkpoint became suspicious, he detonated the bomb. translation: i was in an armoured plated vehicle when suddenly there was an explosion. i was in the back seat, my driver was blown out on to the ground and injured. the area of the attack is home to foreign embassies and the city's police headquarters. the road had been closed to public transport. the taliban claimed responsibility. this is their second deadly assault on the city in the space of a week. 20 people were killed in an attack on the intercontinental hotel last week. this evening, work was continuing to clear the scene of the latest bombing. this is a very secure area and security is very tight here usually and the question will be how they got through this far. the afghan military, backed by us air power, has intensified its campaign to drive out the taliban

from its rural strongholds. but, as today's strike proves, they're still able to mount deadly attacks against civilian targets in the heart of the country's major cities. the release of the black cab rapist, john worboys, from prison has been put on temporary hold, following a legal challenge by two of his victims. the 60—year—old was jailed for a minimum of eight years in 2009, for the rape and sexual assault of women across london. lawyers representing the women were granted a stay on his release, after making an urgent application to the high court. homes and businesses in paris are on high alert as the river seine threatens to overflow its banks. weeks of rain have pushed the water level up and it's thought the river will peak six metres above normal. museums including the louvre have been shut. in smaller towns along the seine,

people are having to use boats to get around flooded streets. in the last hour i spoke to james barisic, a lecturer in the city — he told me how the river is looking this evening. it's high but it's not causing any panic. it's saturday night and the bars and cafes are open and we have not run out of wine and coffee and we are getting on with things. laughter wine or coffee, i love it! what are the parisians saying about it? to be honest, i've spoken to some, and the people i've spoken today who i have been lecturing at the school, and staff there, and there hasn't been great concern. they are seeing this rise and there is information on the paris government website. that's showing that there is a risk of some flooding, predominantly locally to the cellars in some of the buildings which are now used for parking and people have moved stuff out. but frankly it is the weekend

and there's nothing we can do. there's a feeling there that nothing that can be done, so why worry about it and let's get on with it. you are quite close to the seine, can we have a look? just so people can get their bearings, that's notre dame over there, and we are... that should be able to get under that quite comfortably, but it can't, as you can see from the size of the people that are walking over the top. it is extremely high. my understanding is that it will continue going up a bit until tomorrow and then it will start going down again. fortunately it has not been raining today. i suppose it's the water flowing through. are you worried?

do you have plans in place if the banks burst? no. i don't live here. i live in brittany where it is perpetually wet anyway so we are not that concerned. i'm getting on the train tomorrow and the trains will be running and if not, it won't be because of this. i wasn't planning a walk down the seine today, and your viewers may know... they may know there's a walkway that goes down the side of the seine and that is the walkway — it doesn't exist all the way along. so for most people it's not having much effect really, other than to have a look, just as a spectacle. but apart from that, most people are quite relaxed about things at the moment. the headlines on bbc news: three teenage boys have been killed when they were hit by a car in west london. a man has been arrested. the attorney general has acknowledged that "very serious mistakes",

over the disclosure of evidence by prosecutors, have led to the collapse of recent trials in england and wales. at least 95 people have been killed and more than 160 wounded, in one of the deadliest attacks on the afghan capital, kabul, in recent months. sport now and a full round up from the bbc sport centre. it's been a busy day in the fourth round of the fa cup with a couple of premier league casualties but tottenham hotspur narrowly avoided an embarrassing exit at newport county. the league two club more than held their own and the rodney parade crowd erupted when newport went ahead through padraig amond. a big upset looked on the cards until harry kane got the premier league giants out of trouble with eight minutes left on the clock. newport fans can at least look forward to a trip to wembley for the replay. delighted. like i said, which we

held on, it would have been the biggest result in the history of the club, for financial reasons and everything, but i'm so proud of my players. they gave everything, and the second half., we knew they could come at us and we could not get out much, but they didn't switch off and they stuck with the game plan and they stuck with the game plan and they followed their runners and i'm so they followed their runners and i'm so proud of them. west ham were the highest profile casualty in today's fourth round ties. they lost 2—0 to league 0ne wigan athletic. will grigg scored both goals. liverpool are also out after being beaten 3—2 at home by west brom. jay rodriguez scored two goals in quick succession after roberto firmino. ajoel matip own goal then put west brom 3—1 up and even a late mo salah strike couldn't save liverpool. all the results are on the bbc sport website and match of the day is on in about ten minutes on bbc one.

in the scottish premiership, celtic moved 1a points clear at the top after beating hibs1—0 aberdeen climbed above rangers — who play tomorrow. the dons beat kilmarnock 3—1 with two goals from scott mckenna and another from niall mcginn who ran round three—quarters the length of the pitch to score aberdeen's third. a dream come true is how caroline wozniacki described becoming a grand slam champion. playing for nearly three hours in 30 degree heat in melbourne, the second seed from denmark defeated romanian simona halep in three sets to win the australian open. it took her 43 attempts to win a slam — and her reward isn't only that shiny trophy. she'll also become the world number one. she was playing really well and i was thinking it looks like it may not be my day but i was never really nervous. i was just going to go out there and give it my all and swing for it and play aggressively. i think i played well. it could have gone either way

but i'm happier it went my way. rory mcilroy will tee off in the final group tomorrow at the dubai desert classic — chasing a first victory in 17 months. the four—time major winner is just a shot behind leader haotong li on 19 under par. mcilroy shot a third round 68 — aided by two birdies in the last three holes. it was good to make the birdie at the last and stay within one of lee. yeah, i will need to play better tomorrow to win, but it is two weeks into the season and i've given myself a second chance to win a tournament so looking forward to tomorrow. and now rugby union. english sides had a good day in the anglo welsh cup saracens, harlequins and leicester all beat welsh opposition. london irish thrashed a much changed wasps line—up 66—7. bath made it three wins from three against newcastle. worcester beat exeter whilst george north missed northampton's victory against sale.

the professional darts corporation are to stop using so—called "walk on girls" after talks with broadcasters. this weekend's masters will be the first where no women will accompany players to the stage. world number one michael van gerwen says the tradition should end whilst his compatriot raymond van barneveld is supporting a petition to reinstate it. that is all the sport for now. one of the world's richest men, prince alwaleed bin talal, has become the latest high—profile figure to be released in saudi arabia — after a major anti—corru ption drive was launched in november. a saudi official has said the prince was released after a settlement was approved by the state prosecutor. but the prince said no charges were brought against him, and no deals had been done. 0ur arab affairs editor sebastian usher reports. just hours before his release, prince alwaleed bin talal

gave his first interview from the gilded cage of the ritz carlton hotel. in hard cash terms, he has been the biggest catch of the saudi purge. the idea of a man worth $17 billion being reduced to sleeping on a mattress while bargaining for his freedom has been a powerful one, and an image he was keen to dispel as he gave a tour of the suite where he was held in recent weeks. i have been all the time here at this hotel. it's been fine. i have exercised, i stretch, i swim, i walk. i have my old iphone, so it's like home. i call my family every day. i'm in touch with my office every day. my private office, my kingdom office. everything is functioning. the saudi attorney general has said that 90 detainees have been released after charges were dropped against them while others have reached financial settlements to win theirfreedom. around 90 are believed to still be in detention. some will go to prison

and face trial. the man behind the anti—corruption drive and all the recent startling shifts in saudi arabia is the crown prince, mohammad bin salman. it's part of his ambitious plan to transform the country, economically and socially. finally weaning it from its twin dependance on oil and religious austerity, as well as granting women basic new rights such as for permission to drive. his vision 2030 project needs massive funding, and the authorities say the purge should deliver at least $100 billion to state coffers. those who cooperate might be somewhat lighter in cash, but they should be able to continue with their businesses and their lives. but it's still a risky move which could consolidate the crown prince's power or build up resentment against his dominance. sebastian usher, bbc news. elderly survivors have gathered in auschwitz in poland to mark holocaust memorial day.

six millionjews, and millions of others were murdered in concentration camps by the nazis during the second world war. evening prayers have been said at the former auschwitz—birkenau concentration camp, and tributes paid at the monument to the victims at the site. a mural by the world famous graffiti artist banksy has appeared in hull. hundreds of people have been turning up to see it on a disused bridge in the city. the artist has appeared to confirm that it his work on social media. not everybody is happy about it — one city councillor said today, it's vandalism and should be rubbed off. matthew bone has the story. the bankside area of hull is no stranger to graffiti, but this latest addition is a little different. the artwork certainly looks like a banksy, and the artist seemed to confirm its identity on social media. it's caused a lot of interest.

this is a quiet, old industrial part of hull, but ever since rumours of the banksy appeared last night, a steady stream of people have come here today to check it out for themselves. it's really good. fantastic. i like the way that the writing on that is like on a chalkboard or a school. i like his shoes. he has got a nice pair of shoes on. you've got to wear a nice pair of shoes. of the hundreds of people who have come along to see it, gavin is more excited than most. a lifelong banksy fan, he works just around the corner. for me, personally, the culture i grew up with, it is a dream come true. what does the mural mean? it depends who you ask. the bridge is raised. it is the drawbridge. for me, hundreds of years ago, we never let the king into hull. a sort of defiance, a sort of challenge. it could have been to do with us voting out, for brexit. it's all about pulling up

the drawbridge again. not everyone is happy to see the graffiti appear. 0ne conservative opposition councillor has an idea of what to do. record by whatever means we can banksy‘s contribution to that piece of work. then clean it off. it is graffiti. all graffiti is damage. if banksy wants to create real art, and i'm sure he does, then perhaps it might be a good idea to buy some canvas. the graffiti has already been graffitied, with some green spray just nicking the toe of the mural. this afternoon, new fencing was put up to prevent people from getting up close. now the weather with darren bett. mild conditions will return on sunday. the mild air is coming from the mid—atla ntic. it from the mid—atlantic. is mild air,.

the skies have a cleared little bit but further north we have windy conditions. by the end, more cloud comes in, meaning more hill fog in wales and more rain in northern ireland and sneaking into scotland so the temperatures rising at the end of the night. as it cloud throw over. cloudy for most of scotland on sunday morning although the far north is not as windy and they might have some sunshine. central and southern scotland, it is wet, with a damp start for northern ireland. drizzle is over the hills of northern england and wales and the south west. elsewhere, probably dry, probably cloudy and very mild, temperatures about 10 degrees. sunday, it stays wet across central and southern scotland.

damp and cloudy around the hills and western england, and a generally cloudy scene. mild, typically, 12—13. temperatures could be even higher. colder further north, north of the weather front which is producing the rain in scotland and the weather front will move south overnight into england and wales on monday, and brings about a change as we change our wind direction. the mild air will be swept away to the near continent and something colder will follow. ahead of the rain, we have gusty winds, the higher temperatures in southern england where it is wettest in the afternoon, and eventually we have sunshine for northern england and northern ireland and scotland where there might also be a few wintry showers as the air gets colder. on tuesday the coldest start in the south of the uk. dry and bright but increasing

amounts of cloud. turning colderfrom midweek.
