mean for traffic in kent? that cannot be allowed to happen. the kitchen like cooking is a serious business. it gives me a reason to get up in the morning, get dressed and get out there. and, the world of strictly dog dancing. it couldn't get more tense, could it?” strictly dog dancing. it couldn't get more tense, could it? i and natalie graham with an told stories closer to home, from all around the south—east, this is inside out. hello, and welcome to the programme, which comes to you from dover. brexit is coming and some of the biggest changes in the south—east are going to happen right here in this town. tonight, we can exclusively

reveal academic research that makes remarkable productions about this region once we leave the eu. on the 23rd ofjune 2016, the uk voted to leave the european union. june the 23rd, independence day! this means there could be changes ahead for the people, and goods crossing the channel. dover and eurotunnel at folkestone par of written‘s busiest frontiers. for now, they are frictionless. at the moment, we have what is considered to be a free—flowing

border between britain and the continent. lorries don't have to and undergo customs check unless they are coming from a non—eu country. that could all change after brexit. really very concerning for us. nobody knows what is going to happen. there seems to be a lack of information about what brexit will mean for dover and folkestone, so we have decided to do our bit to help. we have commissioned a special reports looking into what could happen to traffic as a result of post—brexit border changes. imperial college london has a world—renowned transport research centre. dr ke han is an assistant professor. he carried out the investigation for us with state of the art traffic simulations.

for the purposes of this research, we're assuming that it currently takes two minutes for each vehicle to pass through the border checks at the port of dover and eurotunnel. the research focused on the m20 and a20 and nearby local roads between maidstone and dover. this is what the traffic looks like now with a two—minute check per vehicle. the red lines on the maps show the traffic heading for dover and backing up in a very slow moving queue. as the day goes on, through the afternoon traffic peaks at evening rush hour. the journey between maidstone and dover can take up to two hours, with traffic queues of up to ten miles. but what if there's friction at the border? dr han looked at what would happen if we assumed the border check time is increased byjust one minute per vehicle. in a one minute extra check scenario, traffic becomes more congested. the queues from dover and eurotunnel can approach ashford and affect local traffic

in the afternoon hours. the combined queue length in this case can be up to 20 miles, and it can take up to 3.5 hours to travel from maidstone to dover. so dr han predicts that the cumulative effect of one extra minute per vehicle would result in 20 miles ofjams and a maidstone to doverjourney time of three and a half hours. then dr han looked at what the impact would be if check time was doubled, adding another two minutes to existing checks on every vehicle. the traffic condition on the network becomes far more congested. the queues from dover and the eurotunnel, in the afternoon rushhours, can go as far as maidstone, making the entire study area into slowly moving traffic. in this situation, the combined queue length can reach up to 30 miles. and it can take up to five hours' drive from maidstone. i think people would be pretty horrified by that. yeah, that's very bad traffic. so with two extra minutes

per vehicle, dr han predicts 30 miles ofjams and a maidstone to doverjourney time of five hours. and what is shocking about the research result is that the check time is as little as two minutes of check time increase, applied to each individual vehicle, could lead to hours of traffic delays and tens of miles of queueing on the motorway. norman ives runs his own haulage company based at folkestone and has been in the businesss for 30 years. he delivers food to supermarkets to tight deadlines, so any traffic jams are hugely worrying to him. if he misses his delivery slot, he has to book another and that could mean a wait that seriously disrupts business.

sometimes that can be one or two days waiting. we could potentially end up losing several days a week productivity. just from a two minute delay at the border? indeed. how worrying is that for you? it's very worrying. it's important that other people should see the results of imperial‘s research, and norman's got some ideas about who we should speak to. how about people who live near the m20 ? that's a good idea. we went to stanford — a village which lies near the m20 and to the west of eurotunnel. geoff colledge is a parish councillor. we asked him what he thought of our figures. they're alarming. they are horrific and it will put us into a situation,

a scenario that it will be like an 0peration stack situation on a daily basis. and that cannot be allowed to happen. what is it like? what does it do to your life in this village and other kent villages when you have traffic jams like that? if it's likely to go on a month or longer, as stack has been in operation for a month previously, then itjust becomes worse and worse. the problems manifest. you've got to make sure you have enough food and water in the house beause generally you can't get out. norman, who should we go talk to about this now? how about we go and see eurotunnel? good idea. eurotunnel facilitates huge amounts of trade with the eu — goods worth £100 billion a year are transported through the tunnel. eurotunnel‘sjohn keefe points out

that delays on the motorway could be bad for the economy. those are the goods that our economy relies on, stuck in traffic. that means manufacturing is losing efficiency, it's putting at risk inward investment, employment. so those kind of delays are counter—producutive in their own right. so what we understand from the government today is they want a frictionless border, that will keep the traffic moving as it really should on a motorway. and that's the only way we can envisage running an economy efficiently. the people who run the port of dover told us that dr han's figures support their own conclusions about traffic if there is friction at the border after brexit. the people who run the ferries are optimistic that a frictionless border can be achieved using high—tech methods. guy platten is chief executive of the uk chamber of shipping. i think any delays and intrusive customs procedures which allows those delays is completely regrettable. what we would like to do is avoid that happening in first

place by having a light touch customs arrangement. i think that's entirely possible and technology allowable as well. when dr han did his research, he made no assumptions about what would cause a delay, he simply assumed that post—brexit there could well be one. it seems logical to be concerned that new customs checks could slow things down. but should we also be concerned about passport checks?

at the moment, passport checks on british citizens are carried out by both the british and the french on this side of the channel. it's possible that post—brexit passport checks could take longer. so says tony smith, the former chief of uk border force. it's very possible there could be additional delays at the french border by the french police checking british passports going into eu. if the french are required to ask questions of us or stamp passports, for example, then those transaction times are realistic and that queue time could materialise. but we just don't know yet what the regulatory framework is going to be and there are various options available and on the table where we could reduce that transaction time on both sides. maybe we should speak to the local mp? that's a good idea. in dover, the western docks is undergoing redevelopment to create a large cargo terminal. we met dover's mp charlie elphicke in a waterside cafe next to the redevelopment. he says there is one way to avoid friction at the border. the obvious and logical thing,

certainly at the beginning, is to have a no tariff deal. because that way trade continues to flow between britain and the eu and everyone wins. ireland is not leaving. but these irish lorry drivers are worried about post—brexit delays. any delay in the port at all, it's 0peration stack on the motorway out there. so it's going to be disaster for the whole lot. do you think it's feasible a two minute delay could cause a four—hour traffic jam ? that is what the research is saying. it will cause it. it will. without a doubt. so, the research from imperial college london indicates that this is what the roads will look like if an extra two minute delay per vehicle is created at the post—brexit border. everyone agrees that a frictionless

border would be the best outcome, however it's achieved. it's up to the politicians what happens next. rachel royce reporting. coming up on inside out... louise and her dog, troy, aren't having much luck trying to qualify for crufts. yeah, 0k, we kept going. it wasn't quite the routine we had planned. now, not farfrom here, in deal, there's a cookery school. of course, they are there to teach good cuisine. but in fact they're serving up much more than that. this is the chequers kitchen cookery school in deal.

just give it another stir. as i said, use the back of the spoon. it's the brainchild of pieter van zyl and stephanie hayman. put it on the website, starts at 10:30. so our kind of fundamental purpose is to enable people to learn how to cook, with fresh ingredients, so they can access a healthy diet, but on a budget. and this is one of the most healthy ways of eating vegetables. it's a community interest company, a type of company recognised in law which uses its profits for public good. you won't cut your fingers off, not while i'm here. i don't like doing the paperwork. pieter is taking the keen2cook weekly session today — it's free to people on low incomes, and is funded bya grant from the lottery. then i always, always wash the rice, it's very important to wash the rice. in the class today is chris king.

he volunteers as an assistant, helping everyone to be the best they possibly can in the kitchen. he loves it, because chris's passion is cooking. just salt, when we're roasting vegetables, helps bring out that flavour. ijust find it better going in before. i love cooking and putting a meal in front of someone. it's all about seeing them enjoy my food. it just lifts your soul! shall we do this one as well? so he is really encouraging with some of the participants who maybe lack a lot of confidence or are a bit younger, orjust need a bit of extra support. chris has got a great way of helping them without doing it for them. so if you put that in first, soften it up. chris is very well qualified for this role. 0ver decades, he worked his way up to being head chef in pubs and restaurants across the country, often working 100 hours a week. but one day, that all changed.

sorry... two years ago, i had a massive stroke on the right side of my brain. and i lost the left side of my body. so i was a chef for 30 years and overnight i was nothing, and i had nothing. so i phoned steph and i said, can i be of any use to you? to give me a reason. and she invited me down, and i met pieter, the head chef. and it was the best thing i ever did because i can give back a little something. you know, i've got so much knowledge when it comes to catering, and just felt like it was all wasted.

there is no such thing as "can't" is there? i told you, whoever put the t on the word can, should have been shot. hold that onion tight. it keeps moving. that's cos it's round. so obviously some things are more difficult for him because he's just using the one arm and hand. so to see what he can manage with his circumstances, it's an inspiration. it makes you realise that they can too. chris is planning to invite some of his fellow stroke survivors to the class. he would like to pass on some of his skills and knowledge to them. i want other survivors to realise that even with one hand, you can. sorry... if you can get that can—do attitude, you got a reason to keep

going. it's a big day for chris. today he is not the assistant, he's the teacher. hello, barbara, hello, roger, hello, tony. for the first time, he'll be teaching three members of his stroke club. this is a basic white bread mix, just to make a small loaf. we are just going to crumble the 25 grams of butter into the flour. then just make yourself a well, in the middle. because we're going to add half the water. we can adapt, we can change and make things work for us, if we try. if you use the heel of your hand to break it down. why is mine sticking to the surface?

ijust like being with the people. because they are people who understand how you feel. you're learning, barbara. i'm not! you are! really good, really therapeutic. really good for your brain. thoroughly enjoyable. if anyone has upset me in the week, you can take it out on the dough. and then into your tin. after a short while in the oven, the bread is baked. just check it. but the proof of course is in the eating, so what will they make of it? thanking you. i would highly recommend all this activity, that we have done today, to every single member of our club. there is no such word as can't. so the stroke club class was a success, and chris believes that the cookery school not only

teaches you how to cook but also boosts your self—esteem. for a lot of people, it saves their lives, it gives them that meaning that once a week, get out of bed, go and do it, which is what it gave me. it gives me a reason to get up in the morning, get dressed and get out there. normally i'm asking for help for that sort of thing. now, there's a woman from swanley in kent whose big ambition is to get her dog into crufts. not because he's good looking or best in breed,

no, she's hoping he'll dance his way there. john cuthill reports. it's a wet and windy saturday in coventry. it's raining cats and, well, dogs. and more dogs. they've all gathered here to sniff out a golden ticket. they're competing for a place at the most prestigious dog show in britain. there are ten places up for grabs in each category, here at this semifinal for crufts. excited and nervous, and everything at once. but these dogs aren't being judged on looks. this competition doesn't require a pedigree. this is strictly dog dancing. welcome to the world of heelwork to music. next up, louise ince from swanley in kent, and troy. their complicated routine to flash, bang, wallop what a picture has been

months in the making. you've been really naughty, haven't you ? behave, thank you. helping to fine tune the moves is husband gary. if you can come up, and as i say walk back, you're going to guide him with a sausage, where he needs to go. 0k. walk back. he's gone off again. walk back. the little bits that are going wrong all the time, they are the bits we want to put a stop to. we have to find ways of finding what it is that's going to make the dog do it correctly. keen to maximise her chances of success, louise is entering two categories. and doing a round trip of 160 miles from her home in kent for lessons with gina, a dog trainerfrom hampshire. i still haven't got the ending right. we can look at it. little troy has come on leaps and bounds. he is a cheeky little character.

that is what we try to bring out in both routines, the character of the dog. these are all your props? i've got a better frontage. i was going to say, the frontage is a bit naff. are we going to have photographs on these? you know, i really should, shouldn't i? got the frontage sorted out, photographs on these, and i think we are good to go. # what a picture, what a photograph! photos in place, will troy stay focused and get a place in the final? it's looking good, until it's time to pick up the newly laminated pictures. louise carries on, but knows she is out of the running in this category. the cards come i change them and put stuff on the photographs. he doesn't like them very much. they are slipping in his mouth.

that is why he is mucking about. for louise, there is still a chance that she could get a place at crufts. she has one more routine up her exotic sleeve. troy has to dance his socks off. well done! he enjoyed that, he really enjoyed that. we kept going. it was not quite the routine that we have planned. louise has done well, but competition at this

advanced level is very tough. 0nly ten more dogs will be going to crufts. as the places are awarded, it looks like louise may have missed out. couldn't get more tense, could it? with nine places already called, there is only one place left. thank you so much. i am gobsmacked. i don't know what to say. well done, you did it! next stop, crufts. good luck to louise and troy.

that's all for this week. thank you for watching. goodbye. hello there, is a picture outside at

the moment. we have seen significant is crossing and in wales. we are seeing quite a bit in eastern and southern scotland, as well. amber warning out for the rest of today. specifically part of south wales and the south—western quadrant of england. that is where we are expecting some of the most persistent is slow—moving snow. it is pushing its way westwards, towards devon and cornwall. it has been snowing quite steadily across parts of wales, but it is clearing its way westwards, so following on behind far fewer showers, even than we had yesterday. lots of cloudy weather and a few snow here and flurries there. the showers are still coming in on that strong easterly wind in the yorkshire area. they also coming in to northern ireland, particular and tim and down

—— antrim and down. that snow in the south and west will linger for much of the day. a very slow—moving feature. 0nly of the day. a very slow—moving feature. only a degree or two above freezing for most of us, and bitingly cold in that strong easterly wind. that is starting to ease across the far north of scotla nd ease across the far north of scotland that wind. here, we will start to feel the effect of that high shirt, diminishing the risk of showers. as we go through the night, there will be a hard frost. further south, the penetrating frost for the strength of the wind. it is blowing that snow out of the way, but by and large, because higher pressure is thinking southwards, it will cut of this easterly wind, this bitter siberian winds we have had. the most

of us, much drier tomorrow, brighter, some sunshine, some cloud coming down the north sea coast. it will still be called, and it will still be icy. very icy than the return to work tomorrow morning, but then as the week bears on, tebbit is recovering, perhaps double figures inafew recovering, perhaps double figures in a few spots which is a bit more springlike than it has been in the... this is bbc news. the headlines at eleven. another cold snap leaves
