the headlines: at a summit in brussels, there's been disagreement about how to implement a deal to control migration from outside the eu just hours after it was signed. france and austria have already ruled out hosting secure centres for migrants, a central plank of the agreement. canada has responded to president trump's tariffs on steel with retaliatory duties on more than twelve billion dollars worth of american goods. the canadian tariffs, which come into effect on sunday, target us steel, aluminium, and consumer goods ranging from orange juice to toilet paper. police in maryland say the gunman who shot dead five people at a newspaper office would have killed even more, if he'd had the chance. the man who carried out the rampage has been identified as jarrod ramos. he's been charged with multiple murders and denied bail. the carbon dioxide shortage which has hit britain's food and drink industry has now spread to crumpets. the simultaneous shutdown of several major carbon dioxide plants is effecting supplies of many everyday products, including soft drinks, beers and meat. here's our business

correspondent, emma simpson. her report does contain some flashing images. crumpets, one of our favourite treats. they should be making 25,000 of them an hour at this factory. but the production lines have ground to a halt. two of warburtons‘ big bakeries have run out of c02. this is the point at which we package our crumpets and here we fill every packet with c02. that helps us maintain the freshness and quality of our product over the shelf life. i've got two plants here that haven't run for the last ten days. it's a massive impact on our ability to provide our customers. but supermarkets aren't running out of crumpets just yet. it's notjust some bakery products that rely on c02. it's everything from fresh salads, chicken, meat, ready

meals, sliced cheese. because the c02 in the packaging helps keep your shopping fresh for as long as possible. c02 also puts the fizz into lots of soft drinks and beer. this gas really matters to our food and drink supply chain. why is there a shortage? a lot of carbon dioxide is created as a by—product when making fertiliser. plants usually scale back production in the summer, but this year, even more than normal, just as demand for drinks has shot up thanks to the world cup and the hot weather. the shortages are even causing problems in abattoirs. they need c02 to stun pigs and poultry before slaughter. it's having an impact at scotland's biggest pig processing plant. it's been shut since tuesday and we don't actually know when it's going to open again.

added on to that, a number of the packing plants which would take the product and then make it into sausages and mince and things like that use c02 in that and with the shortage those plants have had, it's hard to see how we're going to avoid some disruption to the product on the shelves. at warburtons, they're not sure when things will get back to normal either. but c02 producers say they're working as hard as they can to resume production. emma simpson, bbc news. how can we be british without crumpets? now on bbc news, it's time for the travel show. this week on the show, i am in bulgaria to get an exclusive look inside one of the most extraordinary abandoned buildings in the world. it

is incredible. i discover an unusual way to go shopping in sofia. i will ta ke way to go shopping in sofia. i will take that one. and uncovered treasures near the black sea coast. 0h! theme plays. we are starting off this week in bald area's beautiful capital, sofia. this vibrant european city is the perfect place for a break, laid—back, affordable, and picturesque. with its roman, is ann keen, and ottoman sites, it is

packed with histories. —— byzantine. but part of the history of bulgaria, it was under communist rule. as you walk the streets you can find reminders of the soviet era everywhere. 0ne reminders of the soviet era everywhere. one of the strangest is at your feet. all across sofia there are shops called cleks. they may seem odd as they are alert to the ground, but it is an interesting history. they were bomb shelters. after the fall of communism, people needed to get results will. there was not much money. they had to use these to sell things from. i will grab some mnms! it drops down another 2—3 metres. he has another step to step up to see me. i will ta ke step to step up to see me. i will take blue! after the iron curtain fell, they were some of the first private businesses in bulgaria,

symbolising the country's move towards capitalism. recently, they have taken a modern twist, and many have taken a modern twist, and many have become art galleries, restau ra nts, have become art galleries, restaurants, and even speak easys. 5l restaurants, and even speak easys. sl is one such bar in a characteristic bomb shelter basement in sofia. these arctic walls because it is as it was. —— are thick walls. 0k, 0k, 0k, it is as it was. —— are thick walls. 0k, 0k, ok, this is cool. this is a typical old dairy and drink?m 0k, 0k, ok, this is cool. this is a typical old dairy and drink? it is a very common drink. —— bulgarian. we wa nted very common drink. —— bulgarian. we wanted to give it another usage outside of the kitchen, we wanted it ina outside of the kitchen, we wanted it in a cocktail. signing up for wind rakia cocktail please. —— one.

enjoy. the perfect combination has tomatojuice and enjoy. the perfect combination has tomato juice and spices. wow! 0h, that's nice. there is an ongoing debate about how to make all syria's communists era buildings for the modern century. —— bulgaria. and this could become one of the most tourists draws in all of the country. with me is an architect, she is an expert on the subject. i am excited. it has been a long time i have wanted to come here. it is massive, is in it? at 70 metres high, 60 metres wide, it looks out over the balkan mountains. completed

in1981, it over the balkan mountains. completed in 1981, it was billed as an iconic monument to the nationalist party. this was the birthplace of the ball dairy and socialist movement. —— bulgarian. this is powerful, powerful architecture. following the colla pse powerful architecture. following the collapse of the regime, the building was abandoned, and later shot off to the public as it fell into disrepair. recently, the only people inside are photo hungry explorers who broke in illegally. this is a really big deal, this is the first international team to be allowed through the front doors. we are excited and lucky to be able to do so. excited and lucky to be able to do so. are you ready? 0h, excited and lucky to be able to do so. are you ready? oh, wow. here it is. me first? welcome. it has seen

better days, hasn't it? definitely. it costs the equivalent of $35 million in today's money to build it. since it was abandoned, the yea rs, it. since it was abandoned, the years, they have not been kind. dora, it's... years, they have not been kind. dora, it's. .. it's years, they have not been kind. dora, it's... it's incredible. there's some work to do, obviously, but it is still very impressive. 50 square metres inscribed, the symbol of communism, the hammer and sickle. there is a mosaic on the ceiling, but the entire perimeter is also covered in a mosaic. we have actually more than 8000 square metres inside here. -- a thousand. 0ut metres inside here. -- a thousand. out of all of these, which one is your favourite? over there, with the dragon. it should represent

capitalism and fascism, the enemies defeated by the communist regime. when the monument opened, thousands came from all over the country to marvel at it beauty. there were sound and light shows and talks from artists and poets. 0ne sound and light shows and talks from artists and poets. one person who remembers that time well is this man. he was one of the official photographers for the building. you we re photographers for the building. you were here and you saw this room and is building at its best. what was that like? really, all that is left is the

mosaics and the mosaic on the ceiling. here are the rest of them. it is all gone. what do you feel seeing what it has become? time to be running out for it. if the roof collapses, so will the walls, and the building will be lost. there is a debate about what exactly to do with the monument. those who remember the repression and hardships of the communist era would like to see it destroyed. 0thers wanted restored to its former glory. but dora is working on a

proposal to preserve it as a museum to discuss the past. it does not glorify the communist idea. we do not want to do that. we just want to know history and to understand why it was built. but if we keep it intact and leave the symbols in their present condition, i think it will be much more powerfulfor the next generation to understand. symbol of much more than what it was. communism was a symbol of the ups and downs of bulgaria and what it went through. there is no doubt it went through. there is no doubt it isa it went through. there is no doubt it is a powerful and iconic building, and so it feels worthy of preservation. but it is down to bulgaria itself to remember its past going into the future. sofia has some great fancy restaurants, but if

you want something more close to home, this is the spot for you. this is the outskirts of sofia. she has been serving traditional bulgarian food for over 20 years. it is like grandma's it and in here. what dish should everyone try? —— kitchen. sign me up. that sounds amazing. i will get one. it is served all year round. hot in the winter and called in the summer. —— cold. and here it is. it looks like... it looks like

ice cream. it is extremely rubbery. so... it is quite chewy with mystery crunches in the middle, and very garlicy, but melts in your mouth. it is actually kind of good. still to come on the show. simon's here with tips on copenhagen on a budget and how to find the best spots in croatia. and i go to the black sea to meet a team making some amazing discoveries. so stick with us for that. there we go. if you are covering two bulgaria, this is one tip for getting around. —— travelling to. can you take me to

central station please? 0ne travelling to. can you take me to central station please? one thing thatis central station please? one thing that is important to know is this flick of the head, it means yes, and this means no. it is confusing, but you have to understand it when you come here. let's do it. welcome to the slice of the show that tackles your questions about getting the best out of trouble. coming up, my advice on coastal croatia, and cheap stays in copenhagen. but first, if you're planning to drive in france this summer, be warned that 400,000 kilometres of secondary roads, the speed limit is being cut from 9280 kilometres an hour. there is no grace period, so from the eighth of

july, fines are being imposed. —— 90-80. july, fines are being imposed. —— 90—80. michael is taking his family to croatia. he asks... 0f 90—80. michael is taking his family to croatia. he asks... of all leisure's fine coastal cities, my favourite is split. split has a perfectly good city beach, but if he wa nt perfectly good city beach, but if he want to be a little quieter, head for the islands. and our offshore by ferry, the island is charming. and at the end of your stay, take a trip to the port of trogir, will don where it isjust five minutes by road to the airport. next, owen peak

has been invited to a wedding in new york, and was to combine it with a trip to havana. but he says...” have received advice between the two countries that have addae historically frosty relations. we are uk citizens and their peers to be regularflights, are uk citizens and their peers to be regular flights, and are uk citizens and their peers to be regularflights, and all of the rules i've seen so far suggests that you cannot travel to the us from cuba for tourism, even if we are not us citizens. this is understandable because the rules on flights between the us and cuba keep changing. until one year ago, many individual tourists could fly from america to cuba on what was called a people— people basis. that has now stopped and if you are a person subject to your —— us jurisdiction, and if you are a person subject to your —— usjurisdiction, which you are, you are not allowed to redeem the user ‘s lives. unfortunately that rule only applies going from the us who do make to cuba. site

would suggest that you fly out to havana, then to new york, then back on, and you should not encounter any problem. now here's a question from dilip gilliam. we are a family of three go to denmark in august. it seems to be a bit of a nightmare. it is very expensive in copenhagen, so i was wondering you could help us. -- philip. i was wondering you could help us. —— philip. we are struggling to get anywhere and a reasonable price. accommodation prices in the capital are challenging. i think for corresponding prices in european cities, you are typically paid more by that youtube said in copenhagen. fortu nately by that youtube said in copenhagen. fortunately the youth hostel network offers a lower rate and higher standards. —— high standards. —— that you would pay in copenhagen. you might also want to consider spending some of your time across the bridge in southern sweden, where, in my spirits, hotel prices

are significantly lower than copenhagen. if i can help you with your travel enquiries, please get in touch. just e—mail the travel show. i will do my very best to find you an answer. from me, simon calder, the global guru, goodbye for now and see you next time. welcome to varna on the bulgarian coast to the back seat. this is the area's summer playground. but the site into the beach, if you are a little bit more adventurous, you can go beneath the surface and discover what is hiding. we are meeting some divers yesterday and dagger to take us out on the boat. nice to meet you. due to. welcome on board. —— you too. boat. nice to meet you. due to. welcome on board. -- you too. today i'm heading out with this man and

his team. his was a sharia should practice a few miles off the coast. deepak the gunners nannup from its colour but by its reputation for being a very dangerous sea to grass. below is an uncomfortable number of ship tracks, an attraction for divers and tourists from around the world. —— the black sea got its name. this fishing boat has a special connection with the back. today we are going on a ship which was discovered six years ago and it was discovered six years ago and it was discovered six years ago and it was discovered by accident, this fishing boat brought back its nets. the that we are now, it was fishing committee nets snagged, and it sounded but we are going to. we went down there and we found it. the water here in the black sea can be very cold. a thick wetsuit is vital.

it is a magical experience descending down and suddenly seeing the shipwreck appearing. this particular ship is a cargo ship called the swift. it is thought that it was british made in 1884 and sank in unknown circumstances in 1933. ships in the black sea are far better preserved than in other cities like a mediterranean. the black sea is actually more like an enormous lake that funnels into the mediterranean through the bosphorus. it grates conditions that keep the cracks in tax —— racks intact. —— wrecks. it is incredible down there.

you first one and you see all these incredible moon jellies, the white jellyfish, just floating around you. and that is all you see for about the first minute as you are pulling is done along the line. —— moon jellies. and then all of a sudden the shipwreck looms out of the green depths. but it was incredible down there. there are countless shipwrecks to explore along the black sea coast. mostly they are from the last 100 years or so. but i have arranged to meet a group of bulgarian underwater archaeologists who are making some ground breaking discoveries that are far far although. this man is part of the centre of underwater archaeology in bulgaria. they had been working all along the black sea. but today they are planning to explore a site at the bottom of lake varna, just inland. what brings us to this particular location today?‘ inland. what brings us to this particular location today? , is divers, it will not be a perfect

site to dive. exciting, interesting, attractive. buffer us, it will be beautiful. —— for most divers. attractive. buffer us, it will be beautiful. -- for most divers. it is thought that for a long period it was a bronze age settlement. they are handling the dive flags and making sure that no bus can close to them. like he said, it is his first time on this site. i know the feeling of being on a site the first time when you do not know exact we what you are going to find, especially in a situation like this, where they are looking for a rtefa cts , where they are looking for artefacts, thousands of years old. the team here, together with the centre for maritime archaeology at the university as southampton, and experts across the world, have risen in its groundbreaking discoveries thousands of metres under the sea. they have uncovered what is thought to be the world's biggest cash of a rtefa cts to be the world's biggest cash of artefacts from to be the world's biggest cash of a rtefa cts from a to be the world's biggest cash of artefacts from a variety of agent

periods. thanks to the conditions you, they have been preserved, even cause of road. he finds show how just to make just how important the black sea has been for archaeologists over the ages. after an hour underwater, the dow is an surface. —— the divers. they have found some especial. well. so we have blown. this is like rock, though. this is really old. maybe bronze age, early bronze age. but without the posts, some 30 centimetres in diameter. which reads people did live here in the bronze age. yes. that is a big fine, then. we were not sure if we would find something and i was so happy when i saw this wooden posts protruding from the silt, from the mud. saw this wooden posts protruding from the silt, from the mud” saw this wooden posts protruding from the silt, from the mud. ijust taken over the fact that right next to trash their areas all of this

treasure just to trash their areas all of this treasurejust hidden to trash their areas all of this treasure just hidden from the eye. just if few metres down. it is only a few metres. and there are all these things from the bronze age is laying around. it is amazing. not many fines, but significant fines. yes. —— finds. there are museums along the black sea coast. we are just arriving back to shore. on a work of this morning i did not figure would be able to hold something that normally belongs in a museum in my hands. that is it for this week, but next week we have a food fiesta fear as jo this week, but next week we have a food fiesta fear asjo tries her best to beat the italians at their own game at a pizza eating contest in naples. and adi goes big in london for a day. this is good. eating food that will keep us alive forever. so try to catch that again

if you can. remain —— a reminder that you can follow from the team here bulgaria, goodbye. hello there. for the fifth consecutive day, temperatures in the uk got above 30 degrees on friday, and there could be more to come over the weekend. still plenty of heat, plenty of sunshine, butjust the chance for the odd downpour, particularly on sunday. because, if we look back at the recent satellite picture, you can see this area of cloud that's just been swirling around across iberia. this more unsettled weather is going to drift its way northwards, clipping into the south—west

as we go into sunday. but for saturday, we're going to be drawing in some very warm air from the near continent, so those temperatures are going to stay very high. we start the day between 11 and 15 degrees. notice a bit more in the way of cloud rolling its way in from the north sea. that could take a little while to break up through the morning. so, if you're out and about through the first part of the day, could be a bit of cloud around. but the sunshine will get to work, and there will be lots of it as we get into the afternoon. blue skies, strong sunshine with high uv levels, high pollen levels as well. and as far as the temperatures go, well, look at the extent of the orange shades on our temperature chart — widely in the mid—to—high 20s. some spots, perhaps to the west of london, maybe west wales, again could get up to 30 degrees. a little bit cooler, perhaps, for some of these

north sea coastal areas. now, as we through saturday night, notice the way that the orange colours try to hold on down towards the south. whereas the last few nights have been cool and fresh, saturday night into sunday morning will be a little bit more muggy, a little more humid. 16 there in cardiff and in london. not as muggy further north, nine there in newcastle. but we are going to see more in the way of muggy air wafting its way in from the near continent as we go on into sunday, also this area of low pressure that's starting to churn its way towards the south—west of the country. so here we could see some showers across the south—west of england, into wales, maybe the midlands, maybe northern ireland. also a weak frontal system, which could bring rain into north—west scotland. but everywhere else sunny skies again, and remember that warm and humid air — the orange colours getting deeper, really, across the south—eastern areas.

temeprature on sunday afternoon in london up to around 31 degrees. some spots in the south—east could get to 32. but even further north, birmingham, manchester likely to hit 30 degrees. and then we get into the new working week. low pressure still churning around to the south. good morning, welcome to breakfast with naga munchetty and steph mcgovern. our headlines today: no baths, car washing or hosepipes — water companies warn customers to urgently cut usage as demand surges in the heatwave. from varicose vein operations to snoring surgery — new nhs plans to cut procedures it says are a waste of money and often don't work. hopes for an end to uncertainty for workers at the port talbot steel plant as a merger deal is agreed. as the world cup reaches the knock—out stage, fifa suggest that harry kane's treatment against tunisia prompted a var clampdown.
