Our top story the Prime Minister has said he wont be deterred by anybody from leaving the eu on 31st october. Borisjohnson says hes cautiously optimistic of getting a brexit deal, but the uk will leave by the deadline, whatever happens. Hes due to have talks on monday with the European Commission president , Jean Claude Juncker. Meanwhile, his irish counterpart, leo varadkar, has said hes not sure mrjohnson will be able to make the compromises necessary to get the deal through, and he played down reports that the dup had agreed to shift its red lines about the backstop. Mr varadkars comments werent the only difficulty for the Prime Minister today. In rotherham, he was heckled by a man who told him to get back to parliament. Our Political Correspondent, jessica parker, reports. In the mood to do a deal . Borisjohnson is in yorkshire today, but will hotfoot it to luxembourg next week for brexit talks. During a speech, the Prime Minister was heckled over why he suspended parliament. I am all in favour of oui parliament. I am all in favour of ourmps. Parliament. I am all in favour of our mps. Why are you not with them in parliament . I would say i am cautiously optimistic. Is that a good enough characteristic . Meanwhile, there is this man. He is loud, expressive. I couldnt give a flying flamingo what your view is divides opinion and until the end of october remains the highest authority in the house of commons. The European Union withdrawal. And enact recently passed is designed to force the Prime Minister to seek a delay to brexit, but borisjohnson says he will not, and ministers have talked about testing the law to its limit. Another speaker has fired his own warning shot, saying he is prepared to be creating and upholding the will of parliament. Not obeying the law must surely be a nonstarter. Period john bercow is making it clear he would do what he can to stop any prospect of mps being sidelined when parliament returns, and he has form for defying convention and delivering some procedural surprises. So these latest comments suggests he will not be shy of doing so again. The office of speaker has become irretrievably politicised. And radicalised. It would have been unthinkable ten or 15 years ago of the house of commons to launch a personal attack on the Prime Minister like this. The way through for Boris JohnsonPrime Minister like this. The way through for borisjohnson is far from clear. A crowd of obstacles await, whether it is getting a brexit deal with the eu or getting his way in the house of commons. In a moment, well speak to our ireland correspondent, emma vardy, in belfast, and our europe correspondent, gavin lee, in brussels, but first lets speak to our Political Correspondent, helen catt, in westminster. The phrase we keep hearing is cautious optimism. What is that based on . It is cautious optimism and the emphasis is on cautious, borisjohnson and the emphasis is on cautious, Boris Johnson says and the emphasis is on cautious, borisjohnson says he thinks the rough shape of the deal. He is set to set to go to brussels on monday for his first meeting with Jean Claude Juncker. This is for his first meeting with jean claudejuncker. This is the first meeting he will have had since borisjohnson first meeting he will have had since Boris Johnson became prime first meeting he will have had since borisjohnson became Prime Minister and will also meet michel barnier, the chief negotiator. Expectations from that though are being slightly downplayed, this is seen as another in those ongoing series of face to face meetings that Boris Johnson has been having across europe, already speaking to Angela Merkel and emmanuel macron, so this is another in the series of those rather than this being thought this is massive breakthrough moment. Downplayed expectations here in westminster. Do we assume this is a weekend of continuing behind negotiations, running into that meeting on monday, that you mentioned . We say it all the time but the deadline is getting ever closer. Absolutely, and Boris Johnson again sing today we are leaving on the 31st of october, which is not all that far away, and the government says it is working ha rd to the government says it is working hard to try and reach a deal and thatis hard to try and reach a deal and that is still its aims so the implication is that is ongoing work behind the scenes and we will see how that plays out when he goes to brussels on monday next week and what happens over those days and weeks. Lepers might head to belfast andjoin emma weeks. Lepers might head to belfast and join emma party. Weeks. Lepers might head to belfast andjoin emma party. A weeks. Lepers might head to belfast and join emma party. A curious day in terms of the issue of the backstop, whether the dup may have shifted a bit, then a denial of that, where are we tonight . M shifted a bit, then a denial of that, where are we tonight . It all comes back to the irish border because if there is going to be a deal, there needs to be a breakthrough on the agreement between the eu and the uk on how to deal with avoiding checks on the irish border. An ep, borisjohnsons allies, they have played such a key role because they have had the staunch red lines. And the dup. Opposing any idea that Northern Ireland might have a separate arrangement to the rest of the uk, thatis arrangement to the rest of the uk, that is what theresa may signed up to under the backstop, an agreement which would have voided checks on the irish border per meaning that Northern Ireland had to stick to some eu rules will address the uk did its own thing. They were opposed to created this hurdle to overcome. What dropped on the front page of the times today was the suggestion that some of the dup would soften on those red lines, rode back a bit and allow borisjohnson to get a deal. But that was instantly dismissed as soon as those front pages were published last night by arlene foster. We had the dups brexit spokesman rubbishing those stories, saying they are nonsense. The dup will not accept any difference between Northern Ireland and the rest of. Great britain when it comes to introducing new checks over the irish sea that do not already exist, that is because the dup says gb is its most important market. We are back to the irish border question over how we can reach an agreement, that the eu, the republic of ireland and the dup and Northern Ireland will sign up to. It is proved the most difficult hurdle to ove rco m e proved the most difficult hurdle to overcome all the way. Perhaps we thought there was a chink of hope with that, suggestions overnight slapped down tonight, there was a suggestion there could be this all ireland deal which would have reduced the need for some checks on the irish border but the Irish Government says that does not go far enough and the irish Prime Minister has already said today he believes two sides are still a long way apart. And we will go to brussels as well of course. Gavin lee following all the twists and turns there. Some continuing talks there, gavin, what are you hearing as we approach the end of the week . I have had a Whatsapp Message in the past hour also by a senior official of the European Council who said to me if he could have a euro every time a predecessor of borisjohnson and theresa may, david davis, exit negotiator, dominic raab said the words they were cautiously optimistic time and time again, they could buy a round of belgian pay for all of the people in the European Commission. We have been here before, what has happened today, the language coming from downing street on the site of the water, official saying that is not what they see is the case. It is not a reality. David frost, the convoy for borisjohnson, has been in brussels today, meeting Michel Barniers teams. He laid out according to the representatives for him today that they have a new idea foran him today that they have a new idea for an alternative to the backstop, an sps solution, so checks on food link animals away from the border. The eu says this will not work because if you just have a customs rule the animals, it opens up all sorts of loopholes for smuggling elsewhere, it opens up other possibilities for other eu countries to say, we will take these rules but not x and y. We are going round in a circle as the eu see it despite this new positive movement, and lets see what happens on monday because Boris Johnson comes to luxembourg, meets for the first time with Jean Claude Juncker and also the luxembourg Prime Minister. The optics look good, a sense of movement as we head towards the 31st of october, nobody wa nt to towards the 31st of october, nobody want to see that, but until then, the eu are tight lipped, they are saying what will be said when they see it. Interesting what you were saying about the contents of that Whatsapp Message. It is fairly acerbic wouldnt we all love to be a fly on the wall in those meeting some day . Will want to pay from the british side, something concrete and new . Yes. I get a sense. Michel barnier will pass these cameras a couple of hours ago today, and as polite as the eu chief negotiator is, iget polite as the eu chief negotiator is, i get a sense the abode of their own rhetoric, we hear the same thing time and time again, they are waiting for something new. Maybe there will be something on monday but nobody here is holding their breath. Thanks for now. Just to bring you news about Brexit Associated with. Bring you news about Brexit Associated with. Brexit. In the last few moments, the Times Newspaper has just put on its website, excerpts from an interview with David Cameron. I believe it is running in the times magazine tomorrow but as you might expect they have put experts on the website in advance. Some of them we can we tonight. There is the headline, i know some people will never forgive me, David Cameron the man who took britain through an av referendum. He has been writing a book about all of this. And eu. We have our political correspondence at westminster, looking at what the interview says thus far to see crucially what he thinks about the direction the country has taken over the last three years since he took that decision. So, as soon as our political correct contents have had a chance to read that, we will have more on the views on David Cameron. We will for now take a look at some of the days other main stories. An inquest has ruled that a teenager who died from an allergic reaction to a chicken burger hadnt been made aware of the ingredients in the dish. Owen carey, who was 18, collapsed after eating at a branch of byron in east london in 2017. His family has called for a change in the law to protect people with allergies. Keith doyle reports. It was a meal to celebrate owen careys 18th birthday. But the teenager died a short time after eating a chicken burger and suffering an allergic reaction in april 2017. The inquest heard that despite telling staff he had allergies, he was not made aware that the chicken was marinated in buttermilk something he was allergic to. The coroner said a lack of information on the menu, which did not mention the presence of buttermilk in the chicken, meant both owen and the staff were reassured by it. His family spoke outside the Coroners Court and called for what they named as owens law. Owen was the shining light in ourfamily and his death should not have happened. We hope now that something good can come out of it and we are calling on the government to change the law on allergen labelling in restaurants. The restaurant chain said its procedures were Industry Standard for the time but accepted more can be done to protect people with serious Food Allergies. It is clear that the current rules and requirements are not enough. And the Industry Needs to do more, more to help support customers with allergies and more to raise awareness of the risk of allergies. The coroner concluded owen carey died from a serious anaphylactic reaction less than an hour after eating the meal, a meal he had been reassured would not trigger his allergies. Keith doyle, bbc news. With me is thomas jervis, the solicitor for owen careys family. A desperate situation, fundamentally what more have the family been saying to you, what did they want to come out of todays ruling and all the publicity that comes with it . Come out of todays ruling and all the publicity that comes with mm has been a really long road for this family. They have been through hell and back. They finally got some a nswe is and back. They finally got some answers today following the coroners conclusion. And their primary focus is to make sure that other people with Food Allergies do not end up dying after simply going out for a meal, so they want to see a change in food regulation across the uk. We will talk more about that. A lot of people following the details of this case today would be astonished that a member of staff anywhere would not realise that a certain ingredient was in a certain dish, that they could not then pass that information onto the customer, does what does that say to family about the state of regulations today, the knowledge within the industry . I think there are millions of people in the uk alone with Food Allergies. There is a certain section of people with Food Allergies where it can be fatal. It is serious stuff. We are seeing incidents like this happen more and more often and, in this day and age, you would think that big food businesses like byron would take theseissues businesses like byron would take these issues more seriously. There clearly needs to be a change in the Food Industry as a whole. And when you talk about the change in legislation that the family would like to see, people might be watching, thinking, we heard so much about the case of a girl who died after eating a packet, there were changes after her particular case, but there is a distinction here. Changes after her particular case, but there is a distinction herelj also represented natashas parents in that case. They have achieved what is called natashas low. There isa what is called natashas low. There is a distinction between those two cases. Natashas law meant it is now mandatory to go to full labelling forfood pre packaged mandatory to go to full labelling for food pre packaged for direct sale, so if you were to go into a shop like pret a manger where they make up foods on the premises, they now have to label whether the item contains any of the 1a eu allergens. 0h contains any of the 1a eu allergens. Oh ins case is similar in that we are talking about Food Allergies still but we are looking at it within the context of a restaurant. And the law as it currently stands means that massive chains like byron can get away with providing customers with allergen information verbally if they have a particular notice saying, speak to a member of staff if you have allergies. A particular notice is normally buried at the back of menus in tiny print and, if you are relying on staff provide that Important Information verbally, you can introduce this element of human error, you can get it wrong. So owens law is to provide uk consumers with mandatory eu allergen information on menus in writing as well as having the ability to have that dialogue with staff. It was to be a double pronged approach to make sure that people with allergies say. Thank you so much for coming in. Thank you for your time. Its the most powerful Greenhouse Gas known to humanity, one that can cause terrible damage to the atmosphere, yet most people will have never heard of it. Sulphur hexafluoride, or sf6, as its known, is widely used to prevent fires and accidents in Electrical Equipment in power stations, Wind Turbines and right across the electricity grid. But when it leaks, it can have dire consequences for the environment. And it has been leaking the levels of sf6 have risen rapidly in the atmosphere in recent years. Across the eu alone, leaks have been equivalent to putting 1. 3 million extra cars on the road in just one year. Matt mcgrath investigates whats behind the rise. We are about to witness the startling destructive power of electricity as technicians prepare a short circuit test at this laboratory. This is why industry relies so heavily on sf6. It prevents overloads that destroy in
