this is bbc news. the headlines: it has officially being the hottest day of the year so far, that which is reaching a scorching 35 degrees in the uk ‘s cannabis is set to be legalised, following the high—profile cases of children with severe epilepsy being denied access to cannabis oil. imran khan claims victory in the country's general election. here, lives are being put at risk because of long delays in diagnosing adults with adhd, says campaigners who call for government action. and at half past 11 will be taking and other in—depth look at the papers with lennon davidson and head of politics at the mirror, jason beattie. —— lyn davidson.

the uk has experienced its hottest day of the year so far, with 35.1dc recorded. predictions are that the all—time record of 38.5 in 2003 could be broken tomorrow. however, the continuing extreme heat is calling problems —— causing problems in the nhs, warnings that the health service is facing similar pressures to the winter. passengers on eurotunnel were subjected to delays of up to six and a half hours when the air conditioning on trains failed. john kay reports from milton keynes. wally is suffering. at 86, the heat has made his lung condition worse. he was rushed to hospital after collapsing at home. i fell, fell backwards

into a radiator. took a chunk out. he's now making sure he drinks plenty of water during the heat wave. second time it's happened. and so is don, on the other side of the ward. he came in dehydrated with a kidney problem. i go into the hallway. and the next thing i knew, i'm on the deck. what, you just passed out? yeah. that's scary. it is. here in milton keynes, the heat has led to an increase in admissions including sunburn and sunstroke. we've got more patients needing more treatment and in fact that this time of the year we've got nearly all of our beds, our winter pressure beds already open, and that is a real concern for us. so you're operating at winter levels at the end ofjuly? absolutely, yes. they have put emergency air con on the ward. next to the ambulances today — an ice cream van. but elsewhere in the uk, medical staff have not been so lucky. we have had nurses feeling sick,

dizzy. we had a nurse who had to be hospitalised after doing a long shift in an a&e environment. jane filmed her fatherjohn in london where she said he was suffering on a hot ward. there is an air conditioning unit last tuesday that has not emerged. doors are not allowed to be opened. it is sweltering. the hospital said it was doing everything possible to keep patients cool. so much for getting away from it all, when carriages meant air conditioning couldn't be used. passengers faced delays of. it is a joke, two and a half hours queueing to the check in, sat on the motorway in 3a degrees. fire hydrants were opened to cool people down.

children are having fun. it is like a carnival, but with less fun and more waiting. they have brought in extra water for festival—goers at womad in wiltshire and some places are set for rain. if you're not travelling or working, and healthy there is fun to be had in the sun. the temperatures are creating delays on the euro train, with eurostar passengers facing six and a half hour delays, forcing the company to cancel thousands of tickets. meanwhile, more delays are likely for thousands of commuters tomorrow as train speeds are reduced to avoid problems created by tracks buckling in the heat. nigel harris is managing editor of rail magazine and joins me now. good evening to you.

could you explain, eurotunnel, that sounds a period is —— pretty serious business, cancelling tickets, people baking in the sunshine, the air conditioning has said to have gone wrong on the trains, is this a common problem? not these days. all of the air conditioning at the minute is put under the most increased pressure, so it is difficult to keep that equipment going and it has fallen over itself. when it comes to air conditioning, a lot of people who have to use trains particularly in london and other urban centres will say that air conditioning, we haven't got any at all. one thinks of tube passengers in london having a terrible time. someone tube trains have air conditioning, and they have plans to introduce air conditioning in the tube. all you do is put more hot air into the tube system itself and it isa into the tube system itself and it is a big problem in that equipment is a big problem in that equipment is on its way. what about this

business of tracks buckling. can you explain to us why in this day and age, that should still be an issue? here is the science bit. if you have one kilometre of rail, if it heats up one kilometre of rail, if it heats up to 55,60 one kilometre of rail, if it heats up to 55, 60 degrees, it will be getting onto two feet longer than how it started out. what track engineers do is a peak it down and a physically —— they physically stretch it to the length it would be if it was 47 degrees. so the track is always under that tension. as it gets hotter, that stretch gradually relaxes until at seven degrees. once it gets above, the metal wants to expand but because it can't go lengthwise it debts into a compressive force held in place by the sleepers and clips and particularly the stone doubts down the side of the railway. it can be 20 degrees higher than at

temperature, if we have 35, the railton project is 55 and it is starting to get into the temperature where it can buckle and if i give you a little demonstration, if you have a piece of paper and you pull it it is very strong. very little effort if you push it. that is what will happen to a piece of rail if he gets to that temperature and given that it does happen, it would happen, that is why you have speed restrictions of. there are railways all around the world, one of this —— one doesn't hear this happening in other places. i wish i had £1 for each time i entered this question. so, you can't change the laws of the sixth. it happens everywhere. you stress the rails for that range of temperatures, coldest to the hottest and all that happens in hot countries is you do it to a higher rate to stop it if it gets hotter than their normal rate, track but

will that in there as well. i have also asked, why don't you stretch the rails for a higher temperature here's that has an impact on the other end, in the winter, you have broken rails as they shrink. so it isa broken rails as they shrink. so it is a compromise for the most typical temperatures that you get in your country and at the minute we are starting to get outside of it and thatis starting to get outside of it and that is not usual. many thanks indeed. a teenager is missing after going into the sea at essex, it is thought he had been in the water with a friend this afternoon. the lifeboat station confirmed one boy had been rescued, but the police say the search for the missing teenager is ongoing. specialist doctors in the uk will be able to legally prescribed medicinal cannabis from the autumn, following a review. ministers decided to relax the rules after a series of high profile cases

of children with severe epilepsy being denied access to cannabis oil. other forms of cannabis will remain illegal. tj is 111 and has a rare form of epilepsy. he used to have up to 100 seizures a day, but since he went on a trial of a cannabis oil medicine, he's been seizure—free. he's just full of life and he lights up the room. having seen him go for years and years suffering, going for treatment, endless visits to hospitals. now he's alive. the epilepsy medicine tj takes was developed by a british company at this cannabis research facility in kent. it also has a licence drug for multiple sclerosis. no doubt then that cannabis medicines can work. but a series of sick children like alfie dingley were denied access to cannabis medicines, because

the drugs, produced overseas, has not undergone rigorous clinical trials. he ended up in hospital, having multiple seizures, until his mum was granted a special licence to import the drug. now, parent power has persuaded the home office to reschedule cannabis products to make it easier for specialists here to prescribe them. just impossible not to be moved by what they had to go through, they had to climb mountains on behalf of their children. now, we found licences and solutions for them within the existing law. but the home secretary and i came out of those experiences feeling these rules feel very out of date. alfie is now doing well, his mum said the rule—change will help other families with sick children. this announcement today gives every person in that situation hope that they can try this medication and that itjust might work. i've always been clear that it doesn't always work for everyone, but when it works, it works like a miracle. the government

is adamant that this will not lead to the legalisation of cannabis for recreational use. cannabis remains an illegal class b drug. so the production, possession and dealing of cannabis are still criminal offences. anyone trying to grow this lot at home would risk a jail term. there are more than 100 active compounds in the cannabis plant. this change in the rules should make it easier for researchers to investigate their potential benefits, as well as harms. fergus walsh, bbc news. we can talk to charlotte coldwell, one of the parents who very much campaigned on this issue. her son billy has epilepsy and it was his 30th birthday today. i presume, a very happy 13th day. incredible. --

13th. billy had three present today. celebrating his birthday. he had presence from the family and from the announcement from the home secretary, absolutely incredible, incredible news not just secretary, absolutely incredible, incredible news notjust for billy but for all of the children in our country and all the people throughout the uk who desperately need the medicine. he also got issued with his possession licence today in northern ireland, which means that now i can administer his medication here at home in his own environment, which isjust amazing. now, for the many other parents who hope to benefit from this, there are still some hurdles to overcome. it is not quite as simple as saying it is not quite as simple as saying it is all fine from now on. no, in the interim i think what the home

secretary announced today was that i the autumn, clinicians should be able to prescribe to the people. in the interim, they have set up the expert panel, which is the process that myself and billy have been through this last number of weeks, which is a process where you go to the dock, the doctor fills out the application and the application is submitted to the expert panel and the expert panel then decide. there are three actual things that they decide, one is that the doctor has given permission to actually treat the child with medicinal cannabis, the child with medicinal cannabis, the trust in your area is given permission to supply and administer, import companies given permission to import companies given permission to import the medicine. that is for the whole of the uk, that is what happens in the process with the expert panel. then, for the families

in northern ireland what happens is we have to do then, because it is only in northern ireland, we have to apply for a possession licence. so for the mother or the father or whoever is administering the medication, you have to go through a police search and also your doctor has to recommend that the parent or the carer is fit to administer the medication at home and then you get issued with a possession licence. tha nkfully issued with a possession licence. thankfully today, billy is well and so we can now do that. so the process for the expert panel, going back to your question, it is probably a three—week process, but it is getting the doctor initially to fill in the application that is sort of where a lot of the are struggling at the moment. sort of where a lot of the are struggling at the momentlj sort of where a lot of the are struggling at the moment. ijust wa nted struggling at the moment. ijust wanted to be clear with you, what

are the actual effects likely to be of actually having this treatment? is it very quick, will it make an enormous difference straightaway, will it take a period of time? how will it take a period of time? how will it take a period of time? how will it benefit billy? in his case, he has already been on medicinal cannabis to two years and we spent eight months in los angeles where he went through a programme supervised bya went through a programme supervised by a medical, went through a programme supervised bya medical, medicinal cannabis expert, and as everybody is aware, ea rly‘s expert, and as everybody is aware, early‘s prescription was stopped and under the uk rules it had to be a medicine that actually had gone to a clinical trial, hence that led us to canada where billy was then prescribed medicinal cannabis, a medicine that had been to a clinical trial and here reviewed. —— peer of. —— peer. so, you know, the process now, what

iam so, you know, the process now, what i am trying to say, is getting the doctor convinced that actually put in the application for the patients and then the effects, that depends on what particular medical condition the patient has. in early‘s case with epilepsy, it wasn't the particular product that worked, it took a couple of products, then the medicine has to be micro— ghost slowly. normally cbd first and then in billy's case that was helping to control the seizures, then thc has been added, which has been the illegal component. thank you very much, sorry we have to cut it short, good news today and good news for a lot of people. thank you very much for talking to us. thank you very much. a high court

judge has refused to give the bbc permission to appeal against his ruling that the corporation breached the privacy or sir cliff richard in coverage of a rate on his home in berkshire in 2014. the bbc apologised for the distress caused but wanted permission to appeal because it argues the judgement could threaten press freedom. it will have to decide whether to take the case to the court of appeal. the corporation agreed to pay £850,000 to cover the legal fees sir cliff richard has incurred. let's have a look at the headlines on bbc news. the temperature reached 35 degrees this afternoon at heathrow and hotter in surrey, making it the hottest day. medicinal cannabis will be legalised on prescription in the uk following the high—profile cases of children with severe epilepsy

being denied access to canada's oil. and as we have just been saying the bbc will pay £850,000 to sir cliff richard's legal cost of following his privacy case. the official vote leave campaign spend more than 2.7 million on ads targeted at people on facebook to help it to win the 2016 european union referendum. the us social media giant has released these ads two mps on fake news, meaning everyone, not those that they were aimed at, can now see them. let's go to our correspondent at westminster. what does the data actually show? this data set, which has been given by facebook to the house of commons media select committee contains images and the

text from 1400 adverts placed on facebook by various parts of the vote leave campaign during the eu referendum. these adverts in total we re referendum. these adverts in total were seen between 170 million and 370 million times. they were posted bya canadian 370 million times. they were posted by a canadian company called aggregate i0 on behalf of the official vote leave campaign, , aggregate i0 on behalf of the official vote leave campaign,, a campaign called beleave and the dup vote to leave campaign, and there is some interesting information contained within the data with more than half of the adverts referencing the controversial claim that £350 million a week could be saved if we left the european union. 180 of the adverts spoke about the nhs. another 100 taught about immigration and really what you can get from this

data set is a sense of what the leave campaign was trying to tell people on facebook but also who it was trying to talk to. and you mentioned the dup. some interesting sidelights on the dup situation? yes, absolutely. the dup have been controversial in this partly because they got involved in spending money within the referendum campaign very late in the day, within the last few days of the campaign in fact, and all of the money they spend, £425,000 was donated to them by an organisation called the constitutional research council. they used about £30,000 to place adverts on facebook. this data set contains the details of 40 adverts that was placed on behalf of the

dup's leave campaign by aggregate i0 and of those 40 adverts, remember, they are targeted by the people who placed them, of those 40 adverts, 24 of them were not seen inside northern ireland despite the fact they were placed by the dup, they we re they were placed by the dup, they were only seen in england, scotland and wales, they were seen by somewhere between two and 4 million people. you may remember controversy a few months ago when it emerged the dup paid fora a few months ago when it emerged the dup paid for a newspaper advert in the metro newspaper that only ran in england. well, it appears that they we re england. well, it appears that they were doing something similar on facebook. indeed. well, thank you. the former pakistani cricket captain imran khan has claimed victory in the election. his political party has won the most seats and he's set to become prime minister.

but his opponents claim there was widespread vote—rigging and interference from the armed forces. here's our pakistan correspondent secunder kermani. crowds gathered outside imran khan's home on the outskirts of islamabad, hoping for a glimpse of the man set to become pakistan's new prime minister. he can bring real reforms and we think that he's the only one who can take pakistan forward in the right direction. from inside his home, imran khan addressed the nation. pakistanis across the country watched him promise to create a fairer, more equal society. translation: we will run pakistan in a way it has never been run before. we will provide the kind of governance it has never had. khan first became a star as an international cricketer. in britain he was known for his good looks and playboy lifestyle. in 1995 he married — and later divorced — british socialitejemima goldsmith. he developed a keen interest in charitable causes, one he shared with his

friend, princess diana. after entering politics 22 years ago, he initially struggled but in recent years his anti—corruption message has energised young voters. he has, however, faced accusations that pakistan's powerful military has been working behind the scenes to bring him to power. his political rivals have rejected the results of the vote. we are all united tomorrow in islamabad and we will give our strategy to the people of the country from a united political front, and will spell out our concerns over these historic rigged elections in pakistan. khan's party, though, dismissed those claims. for his supporters, imran khan represents a break with the old form of politics, one that was dominated by a few influential families. imran khan's promised

to create a new pakistan, but as prime minister he will face real challenges. chief amongst them will be reaching out to those who didn't vote for him, as well as continuing questions about the fairness of this election. secunder kermani, bbc news, islamabad. the royal college of psychiatrists has long delays in diagnosing adults with attention deficit hyperactivity disorder are putting lives at risk and in some parts of the country patients are waiting several years for a health assessment. campaigners say the government is failing people with adhd, many of whom face anxiety, depression and suicidal thoughts. symptoms of adhd can include inattentiveness, impulsiveness and hyperactivity. it is often associated with children but it also affects around 1.5 million adults. stephen spencerfrom

affects around 1.5 million adults. stephen spencer from york seems an unlikely adhd patient. he is professional, calm, confident, but the condition has blighted his life and set back his career in finance. it is not that you speak too much or you are fidgety, it is just the fact that may be because you have less ability to retain information you have to get people to explain things more and you know you are not an idiot. you are treated that way and thatis idiot. you are treated that way and that is destroying. stephen was 42 when he was diagnosed with adhd. that is destroying. stephen was 42 when he was diagnosed with adhdi first started asking questions when i was 25 and i got a diagnosis around christmas 2016. i have been to gps on and off all over those times. fewer than 896 of adults with adhd have a formal diagnosis. this clinic in leeds has one of the shortest waiting list. but across the country, people face long delays to get the help they need. there are huge variations in services

depending on where you live. here in yorkshire you will be waiting anything from six months to two yea rs anything from six months to two years to see a psychiatrist who specialises in adult adhd. and for many people that is too long. specialises in adult adhd. and for many people that is too longm specialises in adult adhd. and for many people that is too long. if we look at all of the available evidence what we see is that adhd is connected for example with higher rates of suicide, higher rates of depression and higher rates of other mental health needs. this, in addition to the fact that untreated adhd can in fact physical health, means people can be in a very serious condition while they are waiting for adhd treatment. michelle beckett from harrogate was diagnosed in her 40s. she runs a charity supporting adults with adhd. adhd nearly claimed my life. i was suicidal. how many people have lost their lives because they haven't been able to access the treatment? people are contacting me saying that they have been on a waiting list for three years. we have heard of wait times of over seven years in parts

of the country. the government says early intervention is essential and the national history to full clinical excellence recently updated guidance to make it easier for doctors to diagnose the condition. but michelle wants adhd to have a much higher priority. she has now formed a campaign group which demands equal access to support services. people are contacting me saying we have been on the waiting list for three years and we have heard of wait times of over seven yea rs heard of wait times of over seven years in some parts of the country. this cannot continue because people are suffering. as a society we are not dealing with this effectively at all. there are huge swathes of the population missed out by the education system, the medical system. everything. we will look at the prospect of the weather in a moment. stay with us. we will take a look at the papers with lyn davidson, whitehall correspondent for the sun, and jason

beattie, head of politics at the daily mirror, coming up after the headlines at 11:30pm. now, what about the weather forecast? let's get the latest details. can it get hotter? well, finally we have significant changes to the weather as we reach the end of the week with some much—needed rain in the forecast. thursday was another very warm one across—the—board, particularly thursday was another very warm one across—the—boa rd, particularly in southern and eastern parts, with the warmest day of the year so far recorded in surrey, 35 degrees, scorching hot. thunderstorms have broken out and the heat and humidity, some will be very lively with the risk of flash flooding and the risk of hail. low pressure is responsible for destabilising the weather. this area of low pressure will bring wet and cool conditions to our shores to end the week.

weather fronts pushing to our shores to end the week. weatherfronts pushing into western areas on friday will bring more cloud, rain, heavy thunderstorms clear from the eastern side of england, then more than push into southern and eastern parts later in the day. another hot one in the extreme south—east, the low 30s, elsewhere not as warm as it was on thursday. on saturday and low pressure slap bang on top of us. it will feel very different. more cloud around, outbreaks of rain, one band becoming confined to the north—east scotland, more rain and showers pushing into northern and western areas. some of them might be thundery. i think we will hold onto some dry and bright weather in the south—east. it will be breezy, but noticeably cool, temperatures of 19— 24 degrees. more rain and wind pushing into the south—west of the country on sunday. that is something we haven't seen in quite a while. widespread rain in northern and

western areas. we need the rain. this is good news. south and east, heavy, may be thundery showers. i added the wind arrows on to show how blustery will be, another thing we haven't seen in a while. with the cloud and the breeze and the rain, it will feel a lot cooler with temperatures in the high teens to low 20s. low pressure is still with us on low 20s. low pressure is still with us on monday. another front passing through will bring another spell of rain and showers. and notice them into colours, the blue colours to the west of the uk. we are getting this cooler air in on a brisk west to south—west wind. on monday it is a similar story. more showers to northern and western areas. some better spells of sunshine developing across england and wales but the odd heavy
