police in wiltshire say two people are critically ill in hospital after being exposed to an unknown substance. the man and woman, who've been named locally as charlie rowley and dawn sturgess were found unconscious at a house in the town of amesbury, about eight miles from salisbury where a former russian spy and his daughter were poisoned with a nerve agent in march. it's understood that tests are being carried out at the government chemical weapons research laboratory at porton down. duncan kennedy reports. four months to the day since the salisbury instant and another mysterious substance in wiltshire. this time the property seven miles away, here in amesbury. two people we re away, here in amesbury. two people were taken to hospital after possible exposure to the substance, after police initially thought they might have taken a bad batch of cocaine or heroin. the man and woman are believed to be dawn sturgess and

charlie rowley, we understand live locally and they are both said to be ina locally and they are both said to be in a critical condition in hospital. this man says he is a friend of the couple. he was sweating loads, dribbling, and you couldn't speak to him, was making funny noises, rocking backwards and forwards. there was no response, didn't even know i was there, it was like he was in another world, hallucinating. the bbc has been given this video showing the video on fold last saturday night. a number of firefighters turned up at the property before the couple were taken to hospital. the police have now declared it as a major incident. it was initially believed that the two patients fell ill after potentially using contaminated, illegal drugs. however, further testing is now ongoing to establish the substance which led to these patients becoming ill. at this stage, it is not yet clear if a crime has been committed.

the metropolitan police said today that following the events in salisbury in march, where sergei skripal and his daughter were poisoned with nerve agent, they are now working with wiltshire police. the metropolitan police haven't taken over the inquiry here in amesbury as they did with the skripal case but because salisbury is only seven miles away, the new incident has left many people here in amesbury deeply worried. at least five sites have been sealed off by the police, including this church in amesbury and this part in salisbury. public health england say it's not believe there is a significant health risk to the wider public and testing of the unknown substance is still taking place. duncan kennedy, bbc news, amesbury. gordon perera is with me now. a really mysterious lumber clearly something the police are taking very seriously. notjust police officials in london but national security officials even though for the moment they stress

they are keeping an open mind. six months ago this might have just been seen as months ago this might have just been seen as a months ago this might have just been seen as a local incident but the proximity to where the skripals were poisoned and the similarity in the symptoms this pair it has led to those concerns on the samples being sent to porton down. this could turn out to be some sort of drugs contamination, some other reason why they fell ill which isn't serious in a national security or wider public health sense but they could find the presence of some kind of nerve agent. if that was the case, it would seem highly unlikely that this pair would have been targeted by anyone and then you are facing the possibility that perhaps it is some kind of contamination, something left over from the poisoning of the skripals. those remain the possibilities. officials are trying to wait for those answers to come from porton down before they say anything, so the testing is crucial and they are hoping for an initial assessment this evening. gordon

perera, thank you. police investigating the deaths of 17 babies at the countess of chester hospital have extended their investiagation to a second hospital. liverpool women's nhs foundation trust say there is no suggestion that any of its patients came to any harm. a 28—year—old nurse, lucy letby is being questioned on suspicion of murdering eight babies and attempting to murder another six. judith moritz reports. lucy letby once said she enjoyed nursing babies, as she could see them progress and support their families. now she is suspected of murdering eight infants and trying to kill another six. today, police searches have continued at the nurse's home. forensic officers searching the house and taking items away for examination. detectives are still questioning the 28—year—old about the alleged murders and attempted murders. police say that their investigation is focusing on what happened to 32 babies

at the countess of chester hospital between march 2015 and july 2016. the babies were all on the neonatal unit, which cares for poorly and premature infants. managers here called in the police because they could not explain the unusual number of fatalities and babies who came close to death on the unit. now, the murder investigation has widened, beyond this hospital. during her training, lucy letby went on placement to liverpool women's hospital. today, the hospital confirmed that it is helping the police. they are reviewing what happened to babies on its neonatal unit during the nurse's time there and say there is currently no suggestion that any came to harm. since lucy letby was arrested, the police have also been at the home of her parents in hereford. tonight the children's nurse is still under investigation, being asked to explain what happened to the babies in her care. judith moritz, bbc news, chester. efforts are continuing

in northern thailand to work out the best way to rescue the 12 boys and their football coach who've been trapped in flooded caves for 11 days now. medics have reached them, they're being given food and the authorities are trying to put in phone lines so that the boys can speak to their families. but they say no attempt to rescue them will be made until it can be done safely and that could take months. our south east asia correspondent jonathan head reports from the scene in chiang rai province. no longer alone. the trapped boys now have an army doctor treating them. they even manage a smile. they're being given foil blankets to keep them warm. they are painfully thin. "the food is coming", promises one of the divers. up on the surface, they've been rehearsing for the scenario everyone here is hoping for, getting the boys out

and off to hospital. but it won't happen soon. translation: we need to be ioo% confident in order to get the boys out, and they don't have to come out at the same time. we are assessing the situation and if there is a risk, we will not move them out. the options confronting this rescue operation are just as tough as when they found the boys. they are healthy enough, but they say giving them some basic diving training and pulling them through the flooded tunnels one by one is feasible, and yet we've spoken to sources inside the thai diving team who say that's still too risky, that they may still have to leave those boys down there for the full four to five months of the rainy season. we visited the class of dom, the football team captain, and mick — both trapped in the caves. did they have a message for their classmates?

translation: i want them to get healthy, to be patient, and to come back safely so they can be with us again. come back quickly, there's lots of homework waiting for you! singing other school friends have been down to the cave entrance to see the rescue effort and to sing them good wishes. spirits are high here. but the task of the divers, either in extracting the boys or sustaining them underground, is formidable. they will need all the help they can get. jonathan head, bbc news, tham luang caves, northern thailand. the work and pensions secretary esther mcvey has apologised to parliament for making "inadvertently misleading" statements about the roll out of the government's new welfare

system — universal credit. she said she had mistakenly told mps on monday that the national audit office felt it should be rolled out faster. but the nao said her claims were incorrect, as it had reservations about the process. our social affairs correspondent, michael buchanan is here. this has become a very public row. how embarrassing is it for her? hugely embarrassing for her. one mp said he had never seen such a row in more than four decades in parliament. it stems from a report the national audit office publisher last month on the welfare change and found significant problems with it, some claimants waiting a long time for their payments, pushing them towards food banks and rent arrears. esther mcvey robustly defended this but today she was forced to say some of the claimed she made were not correct. an open letter was published by the head of the national audit office saying it was

odd to hear you say we had ignored recent government changes to the benefit because your own officials signed up dill fund this week before its publication. he also said they did not say that the roll—out of universal credit should be speeded up universal credit should be speeded up at all. so this is an extraordinary rebuke from an impartial observer of how the government spends taxpayers money to a cabinet minister. thank you. the time is 6:12. our top story this evening. counterterrorism police are brought in as two people are left critically ill in hospital after being exposed to an unknown substance in wiltshire. and we'll have all the latest from wimbledon, as serena williams makes it through to the third round in straight sets. coming up on bbc news, we are live on day three at wimbledon, with the top seed roger federer breezing through to the third round with a co mforta ble through to the third round with a comfortable victory. there are plenty of sore

heads and frayed nerves after england's dramatic match against colombia last night. more than 2a million people tuned in to watch as england finally won a world cup penalty shoot—out. their victory against colombia puts them into the quarterfinals where they'll face sweden at 3pm on saturday afternoon. this morning they returned to their base at repino near st petersburg. our sports editor dan roan is there. england's fans will have been forgiven for waking up this morning and thinking it was alljust a dream, wouldn't they? but it didn't really happen, england finally won knockout match at a major tournament, the first time in 12 yea rs tournament, the first time in 12 years and for the first time in 22, by penalties as well. the first time ever, as you say, as a world cup. there does seem to be something slightly different about this england side, not just slightly different about this england side, notjust in terms of the to detail but its entire

approach a mindset and now would you believe, they find themselves two wins away from the biggest stage football can offer, the world cup final is. so how exactly have they done it and how far can they go in this remarkable world cup, which seems full of possibilities? it was the sight england fans feared they may never see — their team finally able to celebrate winning a penalty shoot—out at a world cup. the manager explaining the mindset in moscow that allowed his players to end one of the sport's most notorious hoodoos. we are trying to write our own history and i have talked to the players about that. they write their own stories, we do not have to be bowed by the pressure of the past, and, you know, they have done that. the way they have played, the style in which they have played. so, if you could choose to win that way, you choose to win it every time. when jordan henderson's penalty was saved by the colombian goalkeeper last night, most england fans would have feared a familiar fate. but this team are more resolute, with two men emerging as heroes. first, jordan pickford for his brilliant save...

and then substitute eric dier, who held his nerve to seal victory and send england through to the quarterfinals. so, how have they broken their shoot—outjinx? it is about our togetherness, our mentality, resilience. as a group of lads, the squad, the staff, on and off the field, that is our biggest threat, really. we are that strong and we just reset and went again. if it goes all the way to penalties, our mentality is to win the game. england, who were back in training today, have worked tirelessly practising penalties and undergoing psychological testing to help them pick those players best equipped to handle the pressure, and their scientific approach has paid off. they have practised being under pressure. they have practised for a range of situations, and they have spoken to the players a lot about their mindset, and playing with freedom, about not having the burden of the expectations or the worry of making mistakes. and as a result, i think it allows

the players to express themselves more and to perform at a high level. the first of england's six heartbreaking penalty shoot—out defeats at major tournaments came in the 1990 world cup semifinal against west germany, and their goalkeeper that night believes the side can go one step further. i am just elated. it has been so long since we have had a little bit of success. but looking at it now, i mean, it is there to get to the final at least. i do not fear sweden, i do not fear russia or croatia, i think we are capable of beating those sides. we can play better, and if we do, i think we could go the way to the final, which would be unbelievable. a well—organised and useful sweden side in samara on saturday promises to be another stern challenge, but the first world cup

semifinal for 28 years awaits. and if it has to be decided by penalties, at least these fans can now finally watch with a little more face. dan roan, bbc news, repino. there were jubilant scenes from england fans across the country as the three lions earned their place in the quarter finals of the world cup. it was the young goalkeeper jordan pickford's heroics that helped clinch the victory. fiona trott has been talking to some of those who developed his love of the game. this is what world cup celebration looks like. from leeds, to back gardens in birmingham... backbenchers in westminster. and in sutton coldfield, majorca and london. but here on wearside, nobody was celebrating harder than the teachers at the jordan pickford's old school in washington. during the lunch break today, they relived that world —class lunch break today, they relived that world—class save. lunch break today, they relived that world-class save. he was immensely tough kid in year seven and he wa nted tough kid in year seven and he wanted to win in every sport he took

pa rt wanted to win in every sport he took part in. that penalty shoot out showed the same characteristics we saw here in school. out on the sports field, pupils here are world cup crazy, and jordan pickford is the role model. really proud because he went to our school and everything. jordan saved that. i was all over the place, i don't know what to do. we have the same chance as him now. on the other side of the city at sunderland academy, jordan pickford and jordan henderson's former coach, he has known both since they were the age of eight.|j did not watch it, i went into the family room to watch it. but looking back, i was like an expected father pacing the floor waiting for something to happen hoping it would be something great. this was newcastle's fan zone last night. this afternoon, a much calmer scene,

relaxing in front of wimbledon. thanks to the world cup, business is booming in this part of the city. and if you do not have a ticket and visa for the quarterfinals, travel experts have said places like this might be the best way to watch. fiona trott, bbc news, newcastle. a huge moorland fire near stalybridge in greater manchester may have been started deliberately, according to police. the force is investigating reports that people were seen lighting bonfires on the moorland 11 days ago, shortly before the fire was first reported to emergency services. the blaze went on to cover several square miles and is still burning. a nurse who became the first briton to be convicted for slavery offences overseas has been jailed for 14 years. josephine iyamu trafficked five nigerian women to germany to work as prostitutes. she was arrested at heathrow airport in 2016. judge richard bond told her her vile actions exposed the women to a real risk of death. police on the scottish island of bute say they're treating

the death of six—year—old alesha macphail as murder. tributes have been left outside the home of the little girl's grandmother, from where she vanished in the early hours of monday. detectives say a vehicle has been seized as part of the investigation. trawler crews have welcomed the government's new proposals on how it will manage fishing in british waters after brexit. ministers say that from 2020 they'll be able to negotiate access as an independent coastal state, allowing a fairer allocation of fishing opportunities. but others are warning of new barriers to the eu market for british fish. our scotland editor sarah smith reports from the uk's biggest fishing port, peterhead, in aberdeenshire. british boats are currently allowed to catch only 40% of the fish in uk waters. under eu rules the fishermen think are deeply unfair and the government

is promising will change. when we leave the european union, we'll have control of our territorial waters, and that means we can reverse what's happened in the past. in the past, we've had a situation where more than half of the fish that's caught in our own waters is caught by foreign boats. now we can say that we'll decide who catches that fish. now, of course, we'll negotiate with other countries, but we'll negotiate with our control in our hands. after brexit, the government say we will control the catch in all uk coastal waters, extending up to 200 miles out to sea. british fishermen recognise that eu boats will still be able to negotiate some access to these waters, but they say they hope the uk will double their share. we need access to fish. if we can't get access to fish, well, the bigger picture is the business suffers. no access to fish, you've not got an income. are you confident the government will fight for the british fishing industry? i hope they do, i hope they do! there is, of course, always a catch. most of the fish that's landed

here is sold into the eu, so we'll still need smooth and easy access to their markets. that, say the government, is a totally separate issue, unrelated to allowing eu boats to fish in uk waters. but the eu do not see it that way, and market access is a battle still to be fought. any barriers to free trade could be devastating for parts of the industry, like creel fishing for seafood. with all the stuff they catch, it's only going to the continent, or 90% of it going to the continent. if tariffs get involved, the tariffs mean a hold up, and they can't have lorries sitting waiting at ports with fresh produce on them. a lot of the time the prawns are live, they've only got a matter of hours. there's a timescale in getting them to the market live, that will be lost. fishing is only a tiny part of the uk economy, but it's politically important. regaining fishing rights will be a highly symbolic example

of taking back control. the government's made its position clear today. the eventual outcome, of course, will be subject to negotiation. sarah smith, bbc news, peterhead. tomorrow the national health service will be 70 years old. there'll be events to celebrate its birthday all over the uk. one and a half million people now work for the nhs, making up the biggest care team in the world. adina campbell has been to meet one family who've been part of the nhs for four generations since the 1960s. my name is elaine unegbu and i am a retired nurse. my name is ngozi?edi—osagie and?| am a consultant neonatologist. my name is ndidi and i am a third—year medical student at king's college london. for this family in manchester, working for the nhs has provided lifelong careers. well, i was brought up around hospitals because my mother was a nurse and my grandmother was a cook, and my grandmother

looked after us a lot and we would come to the hospital and wait for her, while she was finishing work, to come and pick us up. i was the first nurse in my family, and i think i am still the only one, because my family just thought nursing was a bit heavy and they tried to dissuade me, but i loved the uniform and that is why i went into nursing. and now your daughter is also following in your footsteps. she is. what is it like to see your daughterflourish? well, i must say, when she first said she was going to do medicine, i tried to dissuade her, actually. but in the end i was really pleased that i had been such a good role model for her. because, ithought, there are so many other things you can do, and when you are in a profession, you always think the grass is greener on the other side. but i actually really enjoy myjob and she said to me, "mum, but you love yourjob," and i do love myjob. so i am quite pleased that she had decided to become a doctor in the end. and it is hard work — the long hours, the shifts, that has not put you off? no, i do not know what else i would be doing, to be honest.

it is sort of... i have just got used to it. and all my friends are in the hospital with me. my mother has recently become associate medical director. i think you are one of the first black women in this position as well, in the hospital, so, i think that is a really, really proud achievement. and i am really proud of her, and we all are. no pressure then, your children years down the line, are they going to continue this legacy? i think we will all get tired of it by then, probably go into something else. who knows? my experience, i suppose, is very different to my grandmother's and is very different to my mother's and probably will be different to my daughter's, but the fact that we have all been able to contribute and we all enjoy what we do, i think that is a great testament to the nhs that we work in and we all love. roger federer is through to the third round of wimbledon as he chases a ninth singles title at the all—england club. he beat slovakia's lukas lazko in straight sets. both serena and venus williams are also thorugh to the next stage, asjoe wilson reports. roger federer, second round at

wimbledon, it was never going to go to penalties. so, get your banner on camera as quickly as you can. other way around. there you are. slovakia's lukas lazko at the top of the screen competed well, but federerjust the screen competed well, but federer just has the screen competed well, but federerjust has that ability the screen competed well, but federer just has that ability to manoeuvre 01’ a federer just has that ability to manoeuvre or a rally and an opponent to his requirements. he won in 90 minutes, exactly. the master on centre court. newcomers elsewhere. on court number three preparing for the biggest match of her tennis life is katie swan, just 19, one of the group of young british woman with real tennis potential. keep the word potential in mind as we watch are serving here against romanian opponent, ranked 28 in the world. there were glimpses and opportunities but in the end, the romanian won 6—0, 6—3. katie swan left court with an idea ofjust how

far she has to go. and so to the gritters, serena williams in 2018 is the superhero checking if she still has all of our powers. that is classic stuff. serena williams was too strong for her bulgarian opponent. but she could be too strong for anyone. joe wilson, bbc news, one can. time for a look at the weather... here's matt taylor. there has been a tiny bit of rain. yes, can you believe it? 29 degrees for scotland this afternoon. tomorrow will be cooler. there has been some rain, look away if you are a gardener. some in the west. here is where we are at the moment. across parts of the south and east wales, and showers. the odd spot will push through into wimbledon. we will push through into wimbledon. we will see some of the showers continued into the first part of the night, most will fade away. mostly
