good afternoon. the health secretary, jeremy hunt, is threatening social media companies with new legislation unless they voluntarily come forward with safeguards to protect children's mental health. he's written to platforms such as facebook and google accusing them of "turning a blind eye" to the problems arising from social media use. our business correspondent joe lynam reports. it is the new worry of the digital age. how can parents better control what their kids are viewing online? studies for childwise found that children between five and 16 were spending six hours a day in front of screens, more than twice the time spent 20 years ago. now the health secretary wants the social media giants to do a lot more or face sanctions. writing to facebook, google and twitter, jeremy hunt said that they were collectively turning a blind eye to a whole generation of children being exposed to harmful material. he said it was unfair to parents and morally wrong. yes, the government are appearing to do

something but they are not actually doing anything. this is about bullying, cyber bullying. we have no control over anything, and to say to google and facebook, it is your responsibility, it is not, it is our responsibility, it is our government. if we are going to do something about it, then we've got to do something about it. ok, this is how this app works. google, which owns youtube, said it understood the concerns of parents and had introduced a family link to set the ground rules for children, including screen time limits. we allow them to have 30 minutes, in the evening, like at six, after dinner. probably everyone, to be honest, is using the internet too much. that includes parents. it is not so much pressure, we do not have an outlet any more. we rely too much on the internet. it is having a lot of an effect on our communication skills. every generation of parents has faced its own

problems be that alcohol, drugs or video games, but never before have so few companies, facebook and google, for example, had so much of an influence on what our children watch or consume. so the challenge for government is to curb excess, reassure parents, but not stifle technological change. labour has condemned the government's handling of the windrush scandal, where some people who came to the uk from the commonwealth decades ago have been threatened with deportation or refused jobs or healthcare. a government minister admitted that he's ashamed of what's happened but insisted the problem wasn't with policy, but the way it's been implemented. here's our political correspondent nick eardley. the empire windrush brings to britain 500 jamaicans. they came to the uk from the late ‘50s to ‘70s, immigrants from the commonwealth, here in part to address post—war labour shortages. but some have recently been threatened with deportation or denied access to jobs or public services because they

could not prove they had a legal right to be here. it's wrong what has happened, it should not have happened. there have been admissions of failure this week, but on the bbc this morning thejustice secretary defended the government's broader record on immigration. the home secretary should not quit? you're backing her to stay in herjob? absolutely. because, when it comes down to it, the central policy is right but clearly there have been very significant failures in terms of how this has been implemented. opposition parties disagree. labour and the snp both say the home secretary should take responsibility and quit. and the labour leader says there is something rotten in government. at the time the tories were pushing their hostile policy through parliament, some of us warned about the consequences this could have for many people and families. people's lives ripped apart because the personal decision and actions of theresa may and her government. a special helpline has been set up to help the windrush immigrants.

the prime minister says they may qualify for compensation. but whether this scandal sees political casualties remains to be seen. and nickjoins me now. the government obviously under a lot of pressure to resolve the windrush scandal but this coming week will be pretty busy as well. regarding brexit. yes and whether or not we should remain in a customs union when we leave the eu. the government suffered a big defeat on this in the house of lords last week. next week, this week, i beg your pardon, mps will get the chance to vote on it as well. that will be symbolic, it will not change government policy, nor bind the hands of ministers, but some who support the customs union now think they might have a majority in support of that in parliament and they are hoping to put some pressure on. the government this morning not budging at all. we had david gauke

on the andrew marr show, asked about that issue as well. he repeated government policy, their policies to leave the customs union and set up a new partnership in its place. he says it is the job of ministers to persuade mps that that is still the right thing to do. he is determined they will be successful in that. opposition parties say it would solve a raft of problems the government is facing, not least on the hard border in ireland. i suspect the debate on the customs union still has some way to go. thank you. in afghanistan, at least 52 people have been killed and more than a hundred injured in a suicide bomb attack in kabul. the islamic state group says it was behind the blast, which targeted a crowd waiting outside a voter registration centre. zia shahreyar sent this report from kabul. the people who were killed and injured here had been waiting in line at this voter registration centre for identity cards that would have allowed them to vote in elections due to take

place in october. the suicide bomber walked up to the building's entrance and detonated his bomb. translation: this kid was innocent. what was she guilty of? she was killed today in this attack. these people call themselves muslims. curse on such muslims. look at this. this is a voting card which is drowned in blood. who will come to vote when the government asks us to? the government hopes to register up to 14 million people in the coming months at thousands of centres across the country but afghanistan's independent election commission is concerned about security. zia shahreyar, bbc, kabul. sir mo farah broke the british record at today's london marathon as he finished third, two minutes behind the winner, kenya's eliud kipchoge. more than 40,000 runners have been taking part in today's race, which is officially the hottest on record. our sports correspondentjoe wilson

is at the finish line for us. yes, iam yes, i am standing a few metres beyond the finishing line. there are some exhausted people here, triumphant but exhausted, temperatures nudging above 23 celsius. that is a record. we have to hope that people out on the course are trying to pace themselves but that is tough because today's marathon has taking even the elite runners for the than they have ever been before. —— has taken. this london marathon began with history. the queen was the official starter. in 1908, the olympic marathon began in windsor, finished in london. on today's start line, at blackheath, more registered runners than ever before. in the heat, the advice was to think carefully before wearing fancy dress. that was the advice. for some, whatever the weather, a marathon isjust a stage. mo farah is learning this race. look for his fluorescent sleeves at the back here, trying to find his own bottle

at the feeding station. "where is my drink?" in the early stages, the refuelling problem seemed to overtake mo farah. the crowd willed farah on and he fough hard, but he was not in the lead. it's eliud kipchoge who is the champion in 2018. eliud kipchoge of kenya, as expected, was the winner. back in third, digging deeper than ever before, came the king of the track, mo farah exhausted, but he had just run the marathon faster than any british man before him. kenya's vivian cheruiyot won the women's race in a personal best for her but paula radcliffe's world record remained safely intact. madi de rozario of australia won the women's wheelchair race. look, as he puts down the power... but look at the blistering finish in the men's event. the black helmet belongs to david weir, 38 years old, doing it again, london marathon champion for the eighth time. yes, one year ago

yes, one year ago we were yes, one year ago we were wondering if david weir was at the end of his career. today he said he is loving life again. mo farah said he felt a new kind of pain in today's marathon. there are thousands of people here who would concur with that sentiment. thank you very much. you can see more on all of today's stories on the bbc news channel. the next news on bbc one is at 5:35. bye for now. hello. after a few days of unusually warm weather, it looks like things will get back to normal over the weekend. that means it will be cooler, fresher, there will be sunshine around but also showers, and fora sunshine around but also showers, and for a while, they the government is to increase the powers available to police and the security services to try and stop terror attacks

on screens around the world. released by the syrian opposition, a video appearing to show the aftermath of a chemical attack. the allegation that chlorine had been used met with international condemnation. a team of experts from the organisation for the prohibition of chemical weapons arrived in damascus earlier this week, but their attempts to reach the site in douma were thwarted when the security team came under fire, leading to a three—day delay. experts say if chlorine was used, that timescale could now make it hard to detect. if it was a chlorine bomb attack, it is much harder to have any evidence at this point in time, two weeks afterwards. chlorine evaporates very quickly. it does not remain in the bodies. it does not remain in the soil, so it will be difficult to find conclusive proof that it was a chlorine attack. america's defence secretary has accused the syrian government of orchestrating the delays while it cleaned up the area. it's now a week since the us,

uk and france launched air strikes in syria against, they said, chemical weapons depots and production facilities. syria and its ally russia have denied that any chemical weapons attack took place. the team of experts will now send their samples for analysis ..except one—eighth your size. but that never held back mini—me... i shall call him... ..or verne troyer. ..mini—me. screams. the role of dr evil‘s smaller clone in the austin powers comedies brought him worldwide recognition.

the men's elite race in third place, breaking the british record. the met office has confirmed it is the hottest race on record, with a temperature of 23.2 degrees recorded at st james's park. our correspondent kate grey spoke to sir mo and asked if he was happy with his third place finish. oh, i'm pleased with that with that in terms of third. today was a big, big, big marathon. as you know, the london marathon doesn'tjust have local guys, it has everyone in it like eliud kipchoge, kenenisa bekele, myself, daniel wanjiru. there's so many guys in that field and to come away with third, i'm pleased. it would have been nice to have, you know, run an even pace, but i had no choice. the guys were going for world record pace. whether you let them go and try and close the gap at the end, and i knew that wasn't going to work, or you go with them and see how long you can hang in there, and that's what i did today. so you felt you kept

to your game plan and did everything you could have done to finish as you did? definitely. i did my best. it would have been nice to have run a little bit quicker, but at the same time, that kind of pace, when you set off at that pace... it's really hard to run a lot quicker than that. our correspondent kate grey also spoke to two runners who found the hot conditions challenging. we can confirm it is about 23 degrees here, but i think most of the heat is actually coming off the ground, off the road. so as they finish here, it is absolutely sweltering. but i'm actually very pleased to say i'm joined by some guests who featured quite well last year. we have david and we've got matthew. people may not remember you, but i'm hoping they will because david, last year you were helped across the line by matthew. this time you've made it through in what looks like good fashion, how are you doing? i'm great, delighted. it's been an amazing day, it's been so much fun out there, but hard work, i can tell you that. was it anything like last year when it came to the fatigue and were

you expecting something similar? no, i wasn't expecting anything similar, but will have caused havoc today for people. i felt i'd gone out and kept the first half quite easy and just tried to press on. but it wasn't that kind of day for pressing. it was good to enjoy the crowds as much as i could and then try and knuckle down for the tough bit. matthew, did you have to keep your eye on him this time round, make sure he was keeping himself well hydrated? no, we've been training together this week and i've seen his training, he's in such good shape. i knew even with the heat, he's a sensible guy and he was going to run it well. it was amazing out there, incredible. i had so much fun. it's so tough, but the crowds just kept you going. when i came across the line, i turned round and david was right there. the first person i got to hug. so it was really nice. was it the plan to stay together? no, it wasjust natural and he stuck on me, didn't he? i didn't see him

at all on the course. that is amazing, over 26 miles, 41,000 people out there and you managed to stay together. what a brilliant way, you must be sort of in tune with each other, i guess. in terms of the heat, how much did that affect, because that has been the story, it has been confirmed to be the hottest london marathon to date? that's what i meant as well with it being tough out there, the course is great, the crowds are great, the fellow runners were brilliant. the amount of people i got to chat with and shake hands with around the course, such brilliant guys, brilliant girls. the heat, it was unbearable, really. we all had to rein it in. finally, matthew, what a year it's been for you. strange to think last year you were just sort of the average marathon runner and then with the spirit of london award, it is amazing that people do like to see that human power taking over and giving back to each other? it's been an incredible year, such an honour to get the spirit of london award and it's been great to run this year with david.

time for a look at the weather with darren bett. hello there. we've got the last of the heat today across the south—east of england and east anglia. it's been a lovely day. probably a bit too warm for running a marathon, mind you, but a lovely day along the thames. we are hitting that heat we have in the south—east. there may be a few sharp showers later, but already turning cooler and fresher in the west. we end the day with sunshine and showers towards the north—west. that is where we will have most of the showers, across northern areas overnight, although even those become fewer and lighter. we will have lowered temperatures, a much more comfortable night for sleeping. no storms, which will help things. tomorrow, a bright start with some sunshine. our weather is coming from the atlantic tomorrow, which means more cloud and outbreaks of rain for

northern ireland into south—west scotla nd northern ireland into south—west scotland and the western fringes of england and wales later. towards the south—east, it should be bright and sunny, another lovely day here. elsewhere, with more cloud, normal temperatures for the time of year. this is bbc news, our latest headlines: social media companies are threatened with new laws by the health secretary, if they don't do more to protect children online. he's accused them of "turning a blind eye" to the problems arising from social media use. ministers may increase the powers available to police and the security services to try and stop terror attacks at an early stage of planning. verne troyer, who is best known for playing mini me in the austin powers films, has died at the age of 49. sir mo farah finishes third in the men's london marathon
