this is bbc news, the headlines: sri lanka's security forces say 15 bodies and bomb making equipment have been recovered in the hunt for those behind the easter sunday attacks. earlier the prime minister said he simply "wasn't in the loop" for a briefing on warnings raised in the weeks before the attack. president trump has urged americans to be immunised against measles, despite previously casting doubt on the vaccination. health officials believe the recent rise in people contracting the virus is partly connected to misinformation about the jab. 270 students and staff are in quarantine after cases were confirmed at two universities in california. severe flood warnings have been issued in mozambique as cyclone kenneth, the second in as many months, moves further inland. there are fears that hundreds of thousands of people will need humanitarian aid.

the liberal democrats have launched their campaign for the european elections next month with a promise to stop brexit. speaking at an event in east london, their leader sir vince cable reiterated his party's call for another referendum, saying that parliament was gridlocked and the country was demoralised. our deputy political editor john pienaar reports. vince cable's last outing as leader, and as tough as any he's known. not that that was his message today, launching the liberal democrats‘ push in the european parliament this was. stop brexit. it's simple. it's uncomplicated. it's unambiguous. we are not iffing and butting. it's honest. not easy, though, squeezed by pro—brexit protests, labour, the tories, and the new party of the centre refusing sir vince's call to work together. you reached out to the new party, change uk, and offered partnership.

they rebuffed you and they are coming after your votes. has that made a very difficult election all but impossible? there are millions of people in the country who are craving an alternative to the extremes. which they are now getting on the right and left from the tory party and the labour party. and they do want people to come together to have a more moderate centrist approach to politics. he was sure pro—europe centrist parties would collaborate, just not this time. the brutal logic of the british first—past—the—post system is staring everybody in the face, that you either hang together or you hang separately. a lot of people may admire a tough fight against the odds, but not enough to much help the liberal democrat, if you believe the polls. they are still carrying the baggage and the blame from their years in coalition government. they've been drowned out by the din about europe, and now they are facing a new party equally hostile to brexit. no wonder they are finding it tough just to get a hearing.

you still blame them for bringing in tuition fees at universities and colleges? yes, very much so, i was a lib dem supporter, and then i went over to conservative because i thought they are all as bad as each other. i think they are on the wrong side of it at this stage, i think they should focus on enabling a good brexit. vince cable is a really righteous man. he has good virtues and i respect him. i think they have to convince people that they are actually a realistic option, rather than a tiny party that cannot have any support. you mean, they've got to get people to support them so more people support them 7 yes. defending a single european parliament seat under a leader pledged to stand down by summer, the lib dems are hoping they'll defy all expectations, though just now that is setting the bar rather low. john pienaar, bbc news. now on bbc news, the travel show. coming up on this week's programme. we head to norway to play some chess.

we check out some mediaeval sat nav by studying a map of the world up close. and lucy takes a bumpy ride to test out two new cameras that could add the professional touch. but first, i'm in the norwegian capital of oslo. an unlikely trend is taking hold, all based on one of the world's most enduring games. an unlikely trend is taking hold, all based on one of the world's most enduring games. in chess tournaments, sometimes a match can take two whole weeks.

and here in norway, it's entertainment. this is a really old game, not anything is brand—new, so why is it coming back here in norway? first of all, because we have a really good chess player here in our country. it wasn't before magnus became the best that it exploded. world number one magnus carlsen was a chess prodigy, first reaching the top of the rankings in 2010. he has dominated the game ever since and still holding the crown atjust 28 years old, it's only kasparov who has held the top spot for longer. by official ratings, he is the greatest player the world has ever seen. i would say my favourite player from the past is probably myself, like, three or four years ago.

but it's not all been about magnus. chess fever has spread here thanks to modern tech and coverage online. it's a show, you have celebrities in the studio, we have a good vibe. one, two, three, and to the four, snoop doggy dogg and dr dre is at your door. it's the whole package. at this point, i should say that this unshakeable grand master has agreed to make a rare media appearance outside tournaments to meet me that he is expecting a game of chess. well i have a one—on—one head to with magnus coming up very shortly. so, i'm optimistic. my strategy is, have no strategy.

he can't read this face if there is no strategy underneath. the bad thing for you is that also that is also often his strategy. so i'd better get practising. ben, hi. hey. nice to see you. i'm here to scrape off the rust. wonderful — magnus will be shaking in his boots. i hope so. at stjernen chess club, weekly tournaments have members compete in the latest trend, rapid chess. with the time limit being just 10 minutes, it's become more popular with rapid chess and blitz chess. you get more games, there's more action and there's also more mistakes. like the one you did now. try to gain control of the centre. if you see the board now... you are in control of the centre.

i can say that because i have two points in the centre. if you try to occupy the centre or at least if you do like this, you see, your bishop is attacking all the way down to my king. i see. so if you want to just keep on doing moves for me, maybe i'll win. if youre playing magnus, i would suggest to try to attack as soon as possible. because if he gets to attack, you'll lose. i think it's going to be inevitable, but either way... people keep on filing in here so it seems like it's very soon to competition time. let's just forget about this game. let's do it. we'll start from scratch. anyone can join the weekly tournaments here and everyone plays five games, even me. the game is about to start, there it is. i'm already late. here is my squad.

have some coffee and the game is on. first time playing timed chess, actually. and it's not going well. didn't even know i'd lost. the club has seen its membership nearly double since magnus came on the scene. nice game. ouch. good game, that was a good game. out of five, we won one but i had a plan, a strategy that was moulded

over the course of five games. ben help me and by the end of it, ifelt some confidence, take that strategy and bring it to the world champion and if i last six turns, that's a win for me. some going to go back home and rest the biggest muscle in my brain, the most important one, and get ready for the match. but get out of the chess clubs and people are playing chess everywhere, online and on their smartphones. i've arranged to meet magnus where they develop his three apps. they have had 5 million downloads. i'm here for magnus, is this the right place? yeah. it is? ok, great. i'm not exactly sure where to go. ah, by the chess board. a good place to find magnus. in this day and age, there's probably a million different games all competing for the spotlight but here in norway, chess seems to be in the front lines.

do you think that your influence on the game has had a long—term impact on the culture of this country? well, i would like to say that it's mostly about the game, that is great and if i played a role in sort of leading people towards realising that, then i'm very happy about it. it is a part of the culture in so many countries, it's truly a global game so i don't think it's going to go away. we've got a timer here and i played my first game of timed chess just last night, but what are we playing today? i will have 30 seconds and you will have 3 minutes. i don't know about your level but i'm guessing the main challenge here is going to be the time. i think so. and so you go first? yeah.

my heart is beating so fast. is that it? yeah. how many seconds was that? well, it was about 20. you only used about 15 seconds of your time? well, a little bit less because the clock ran a bit before i stopped it. well, maybe chess isn't your game and that's totally fine, there's lots of ways you can travel the world and have fun and here is our travel

show list of tips for you. why don't you try your hand at kick sepak takraw, or kick volleyball? dating back to the 15th century, you can find locals playing this popular south—east asian sport in bangkok's public parks, city streets and even in temple courtyards. this game is fast—paced and wildly entertaining with the players displaying an impressive level of speed, agility and even acrobatic skill. if you're travelling alone or have never been one for team sports, and you're injapan, then give pachinko a go. you'll need plenty of skill to play this old—school mechanical arcade game and it's something of a national obsession. though gambling is prohibited injapan, you can bypass these laws by swapping your winnings for tokens which can then in turn be exchanged for cash. although it's not likely to be declared an olympic sport anytime soon, this annual bog snorkelling event takes place in wales

and involves competitors from all around the world donning their most imaginative outfits and snorkelling 60 metres through a peaty and murky bog. warmer and drier spectators can watch from the banks of the trench accompanied by live music and local ale. and petanque, or boules as it's often known, is a game steeped in french culture that seemingly every town has a sandy bouledrome at its centre. a social focal point for locals, the game involves throwing a large metal ball at a smaller metal ball while trying to fend off your opponent, and travellers who like a contest are usually welcome to join in the fun. still to come on the travel show. we find out how mediaeval mapmakers in europe saw the rest of the world. it's a kind of visual encyclopaedia but at the same time, it's really beautiful.

so don't go away. oslo is a beautiful city but there can be problems if you're travelling on a budget. there is a hidden gem right around this corner and if you look at the graffiti, you can probably figure out exactly what it is. norway's take on the humble hotdog is known locally as polse. for the equivalent ofjust a few pounds, you get high—quality hotdogs marinated in a unique broth covered in things like mashed potato, all in a thin tortilla calle a lompe. i heard the hotdogs are a big deal in norway. we love hotdogs. we are eating a50 million hot dogs and we are just 5 million people. we are eating almost

100 hot dogs each every year, per person. per person? that is a lot of hot dogs. once there were well over 100 of these hot dog stands in oslo, but since the ubiquitous convenience stores started selling them, now there's less than five left in the capital. like this. look at that masterpiece. yeah, thank you. home—made mashed potatoes, hand—picked mushrooms, we have home—made mustard, and also home—made ketchup and our main event. it is a hit. mm, so good. the important parts of a high—quality hot dog, there's a click — they have a word for it — the click it makes when you bite it, as well as the temperature. i am doing a lot of talking and not a lot of eating so i'm going to have another bite. and if you are in oslo, come try one of these.

since the first cam recorder was released in 1983, holiday videos have gone from a blurry betamax grey thing you'd only show to family members, to an incredible hdr 4k spectacle filmed on your smart phone and viewed by millions. this month it is a head—to—head between two new cameras that could take your travel movies to the next level. the dji osmo pocket and the humaneyes vuze xr. and to help me test them out, i'm bringing along my mate, tommy, aka youtube‘s gadgets boy. so everyone‘s got a smartphone, right, which means we've essentially all got a camera in our pocket. so what would you say some of the benefits of using something like the osmo pocket over your smart phone? i think for me, i do not want to carry my phone

out and about with me all the time because it is just in your face, everyone can see it. but this is nice and compact and discreet so i canjust — i can even pop this in my pocket and let it do its thing while i walk around and enjoy the scenery. so i am not always looking at my phone, when i'm recording things. i can actually be in the moment as well. so perfect for travelling. we are putting these cameras through their paces on a speedboat ride down the thames. so tommy, you're armed with the oslo pocket. so my camera is a little bit bulkier than yours but what's interesting about it is it's far from your average camera. i am looking forward to see what this thing can do. should we cast off? yes, please. the chief selling point of the osmo pocket is its 3—axis gimbal stabilisation, that means video that is smoother and steadier than your average camera. wow, this is amazing. i can actually see what i am recording on there. it looks really stable. my arms aren't aching because it is nice and light.

i think there's nothing more i can ask from a pocket camera. the vuze xr also offers some stabilisation, but it's big feature is 5.7k resolution and the 360 degree video, or, when the lenses are flicked out, a virtual reality 180 degree angle. formats which give it your footage that extra bit of immersion. i know this is a quality kit but, unlike the osmo pocket, there's no screen, which i think puts me at quite a disadvantage. i can pair it up to my app review finder but i don't necessarily want two devices in my hands so i feel like i'm losing out a little bit. it is one thing filming at a gentle speed but how does the footage compare when the boat throttles up?

ok so i've got a question for you, would you use your osmo pocket for your youtube videos? i really would, i definitely would for this, like, when we were on the boat, here, it was very stable — so stabilization on this is amazing. there's a modem there that follows — it can follow me so it can track my face. so it is almost like carrying a bunch of cameramen around with me. so that's a big thumbs up from tommy for the osmo pocket. but what about the vuze xr? it's stabilization might be more limited but its 360 degrees capture offers the chance for a more engaging experience. so viewing your video on a vr set like this is pretty impressive, the high—quality visuals only serve to make the footage feel more immersive by giving you an alternative and awesome option to enjoy your handy camera work. finally this week, we head

to cathedral city of hereford, in the south—west of england, a place that has attracted worshippers of the centuries but many have also been drawn to one of its more unique treasures — the mappa mundi, the largest european mediaeval map of the world to survive to the present day. we went to take a look. hereford cathedral is wonderful because it's got so many ancient treasures that were not swept away at the reformation or lost during the civil war, such as the mappa mundi, the chained library and we have one of the first 17 magna cartas here. it is a great mystery how we have the mappa mundi. it has the equivalent status of a world heritage site in a single object. mappa mundi is usually translated as "cloth of the world". it is by far the largest mediaeval

world map to survive. the map has pilgrim routes and trade routes that you can trace on it, but it is not primarily intended as a navigational map. hereford it is depicted on the map and it is shown more in wales than england. it has almost been rubbed out because, over the centuries, people have put their fingers on hereford. "this is where we are". it shows lots of strange peoples and beasts on it. some of them are very odd to us today. all sorts of people of different races, some of them depicted with dogs heads or faces on their chest.

the map has one or two discriminatory images. there's a not very complimentary image ofjews. there are lots of other images around the outside of the map which reflect races that people were perhaps suspicious about or did not know anything about. but these also appear in pliny‘s natural history. in a sense, you could say that it is presenting what was convention of the time. the hereford map is most definitely a work of art. i would not call them races — that is a modern term. they were a marvellous peoples and they demonstrated the wondrousness of god's creation.

in a way, perhaps, it is a little bit like, in today's world, people saying, do little green men exist? some will say, "yes, there are people in outer space, yes, there are other races on other planets" and others will say, "no, there can't be". mappa mundi it's just a wonderful creation in terms of its size, skill that were used to create it, and i think it has an incredible impact when you see it for the first time. it gives you some idea of how a mediaeval person might have been kind of overwhelmed when he saw it. it had a huge wow factor. it is a kind of visual encyclopedia but, at the same time, it's really beautiful. the map is obviously based on christian and a western perspective.

jerusalem is the centre of the world. in the middle ages everything was symbolism. the christian year and the way it unfolded it was all a vast symbol system within which people lived and found meaning and direction and hope. well, that's all for this week but coming up next week... ade is in dubai to get a high octane supercar ride out into the desert. oh, yes! screams.

so make sure not to miss it. remember, you canjoin our adventures by following us on social media but for now, from me, mike corey, and the rest of the travel show team here, by a chilly shore in norway, it's goodbye. hello. it will be a stormy start to the weekend for many parts of the uk. in fact, storm hannah has already brought power outages to parts of ireland. the winds have been escalating through the night and severe gales are expected quite widely around the coast and the hills in the west. this is a deep area of low pressure so late into the season, of course, when the trees are now

in full leaf in many areas so we do expect some damage to trees, buildings, power lines and that disruption to transport. there are warnings out there on the website for this storm, mostly for the winds but not entirely because it looks pretty wet as well. we've had one band of rain moving through the night. this next one coming in becomes a slow—moving feature, so with all the cloud around, it's not going to to be a cold start to this saturday morning, but it will be a very windy one. particularly for england and wales where we're expecting severe gales around the coast and over the hills, but inland we're expecting gales, gusts up to 55 miles per hour, which is pretty unusual anyway, and remember, we are very late in the season now. as well as that we've got this rain which will be persistent across parts of northern ireland, south—west scotland, into northern england, north wales, the midlands, across towards the humber and, with that rain and the wind combined, it is really going to feel quite chilly. temperatures barely reaching nine or 10 celsius. to the south, showery, and to north as well with some good spells of sunshine potentially for western scotland. but some heavy thundery showers around too.

and the afternoon may bring a strong wind to northern ireland, south—west scotland and the isle of man as well as north—west england and north wales. it will still continue to blow a gale or severe gale further south. a very windy day, certainly not a day for the outdoors. but the winds do ease through the night, and that's because storm hannah starts to blow out to the north sea. and we get a ridge of high pressure building for the second part of the weekend. it's not plain sailing but i think for the london marathon probably the better day of the two and almost great conditions for the runners because it will stay cool, we think, quite a bit of cloud around, i think there will be some brightness coming through, and temperatures will be doing a little better than saturday. however, you can still see this weather front draped into western parts, so northern ireland and wales and south—west seeing further dank weather. further east we'll have the remnants of our weather front. in eastern areas, a few showers around. a cool northerly breeze will be much lighter. 12—15 looking like our highs. they're a little bit more respectable from the days ahead. then high—pressure starts the new week so it could be a bit chilly first thing monday.

could be a little bit of mist and fog around, but as the day wears on, we'll start to see this next weather system winding itself to bring some rain into the west. so generally we keep an unsettled picture into early next week. bye— bye.
