president moonjae—in following mr moon's summit with the north korean leader kim jong—un. mr trump said the time and location of his meeting with mr kim was being set. us media say singapore and mongolia are being considered as possible venues. more than 30,000 people in the spanish city of pamplona have protested against the conviction of a group of men for sexual abuse rather than rape. it's the third day of demonstrations. protesters say the verdict is too lenient and sets a dangerous precedent for gang—rape cases. there have been more mass demonstrations against corruption in armenia, with the protest leader rallying support for his bid to become prime minister. the parliament is due to choose a new prime minister on tuesday. the ruling party says it won't nominate a candidate in an effort to ease tensions. the supermarket giants sainsburys and asda are in advanced talks about merging. sources say sainsbury‘s would buy its rivalfrom its american owner, walmart.

the two firms are the second and third largest supermarkets in the uk and, if combined, would overtake tesco in terms of market share. our business correspondent, joe lynam reports. they are two of the best—known brands in the uk, but now they want to merge into one company. the surprise announcement that asda and sainsbury‘s are tojoin up has shaken up the grocery market, and it may affect where and how we shop. in a statement, sainsbury‘s said that it confirms that it and walmart, which owns asda, are in advanced discussions regarding a combination of the sainsbury‘s and asda businesses. a further announcement will be made at 7am on monday. this whopper of a deal could certainly shake up britain's supermarket sector. at the moment, tesco is the biggest grocer in the uk with 28% of the market. asda and sainsbury‘s have almost 16% each. put them together and their combined 2800 stores would hop over tesco into the top spot.

but not everybody likes it. it makes no sense to me at all. the trouble is you've got businesses which are on opposite poles of the mass—market. asda are attracting a younger, less affluent customer. sainsbury‘s an older, more affluent one. as much as you try to bring those businesses together, you will end up undermining both. britain's retail market has already been shook up by the emergence of the german discounters aldi and lidl. and amazon is beefing up its presence in the fresh food sector with one hour deliveries. so this deal could be in anticipation of that happening. but it could yet falter. the competition and markets authority could well say that cutting the number of supermarkets that consumers could choose from is not on. the competition and markets authority will look at this line

by line, store by store, location by location, and that's what their concern will be. will competition lessen as a result of this? so the deal may get approval, but with some very long strings attached. joe lynam, bbc news. now on bbc news, the travel show. this week on the travel show, we help celebrate 90 years of australia's legendary flying doctors service. what a remarkable bit of kit! yes. we investigate the mysterious ghost lights spotted over a town in texas. and we head to china to try out a style of skiing which is reckoned to be over 8000 years old. this week i'm in australia's northern territory.

this massive state covers nearly 1.5 million square kilometres. it is the most sparsely populated part of australia and living out here can be hard. because of the sheer size of this part of the country, air travel has been an important part of life in the northern territory for the past 100 years. it's also the reason that the royal flying doctor service was set up 90 years ago, pioneering the then—revolutionary idea of using planes to bring medical ca re to remote communities. i have come to their central operation based in alice springs airport. from here, the service dispatches emergency response planes all over the northern territory, and it is a busy place. as we arrived we saw one of the planes bringing in patients

from the outback. one of the planes has just arrived. two patients were taken off, whisked away to hospital. it is a perfect opportunity to see what's on—board, as one of the senior flight nurses, cathy, is waiting for me. the service's fleet of planes are packed with cutting—edge medical equipment ready for any emergency. hello. hi! how are you? good, thanks, henry. what a remarkable bit of kit you've got here. yeah. explain what you have here? we have a miniature intensive care unit, really. we have monitoring, we have drugs on board, we have anything to do with what you would see an intensive care unit. we can take anything from a sore toe to a fully intubated patient who has probably had some trauma or cardiac arrest or something like that. how many square kilometres do you cover out of this base in particular? about a million square kilometres, which is about four or five times larger than great britain.

that's a lot of ground to cover. how essential would you say the royal flying doctor service is to the people of the outback? extremely important. it's their lifeline. if they had to come by road, it would be up to eight hours by road, and the roads are not always that good. there are camels and donkeys and potholes and water. as opposed to probably up to a one—hour flight. so they get into definitive care much quicker. but the high—tech standards we see today didn't just happen overnight. 1917 founder reverend john flynn first had the idea of creating a flying doctor service, but it took him another ten years to turn his plans into a reality. the first planes took to the skies in 1928. those first planes were very basic boneshakers by today's modern standards, but slowly innovations

like pedal—powered radio were introduced, helping to build a lifeline between the flying doctors and the remote communities they served. newsreel: this time the doctor is landing on a regular periodic visit. the sisters are waiting as it lands, welcoming former raaf pilot robert chadwick and dr miller. news of the success of those early pioneers quickly spread, and eventually the service became a national network across australia. in 1955, queen elizabeth visited from the uk to officially bestow the service with its royal title. today, as modern planes and medicines save even more lives, the story of the flying doctors continues to capture the public‘s imagination around the world. tourism is a crucialform of income for the service. here at the flying doctor tourism facility, visitors can learn how the service works and what flying was like back in the day. 90 years of history are brought to life with some of the objects that made it all possible.

even the building itself is historic. this building behind us was the original building in alice springs. this is where we ran our head office and also our communications department. so it's a listed heritage building, and it's now a tourist facility and cafe. as well as educating tourists about the service, the facility and shop are a crucial source of income. so how important is tourism to funding services like the royal flying doctor service? tourism is extremely important. 100% of our profits from the tourist facility go back into the royal flying doctor service. it helps fund the purchasing and also the medical equipping of our craft. 25% of ourfunding is a gap which needs to be filled and that is where our money comes from. over the decades, the flying doctor service has saved countless lives.

it's amazing to think that it's thanks to a small—town church minister who wanted to do his bit to help people living out in the bush. something tells me he would be very proud of the people who still fly to save lives today. we have gone from just a few planes to 67 aircraft, from 2a different locations in and around australia. next up, we leave the australian outback behind and head to america, where for over a century people have reported seeing strange lights next up, we leave the australian outback behind and head to america, where for over a century people have reported seeing strange lights on the horizon in the texan town of marfa. no—one is exactly sure what they are, but many people claim to have seen them, so we went to meet them.

this is the rambling boy, broadcasting live from the radio studios in downtown marfa, texas. i want to say a few words about marfa. it's a very small town, 2000 people. it was a cattle town and a ranching town for many, many years. we have become an international arts centre. but we are still a small texas town and it's an interesting combination. i have never seen the martha lights. i have been told that the best time to see them is in the winter. a couple of hours after sundown, or a couple of hours before sunrise. a couple of hours after sundown in the winter is my suppertime. and a couple of hours before sunrise is my sleeping time. and besides that, it's cold out there in the viewing station in wintertime. but i believe they are there.

at least, i believe something is there. because i know a lot of reliable people who have seen some sort of light out there. scoffers will tell you that the marfa lights are the lights of automobiles travelling north from presidio on highway 67, or the lights of aeroplanes, or ranchers on mitchell flats, or a border patrol helicopter. many people who think they are seeing the marfa lights are undoubtedly looking at automobile headlights or ranch lights. but it is clear that there were other lights out there before there were either automobiles or electricity, and they are still out there. i grew up in marfa.

i was born in 1950. so i've been around, i have seen the lights and i've heard about them all my life. we show the lights regularly to people from our ranch. today we're in front of the viewing centre which is on the road between martha and alpine. it does cause some confusion because of the way it's pointed. the orientation points you to where it's easy to be misled by automobile lights, which are coming up from presidio and 0jinaga. not very many people know that from right here,

there is a mesquite tree right there, and if you stand about ten yards from the mesquite tree and look straight ahead, there's a bush, there's another green bush, and you'lljust see a line, if you really look, of little green bushes that form a line out to a tree, and that tree is about a mile and a half away. right over the tree is where the lights are. i don't remember a single time that someone didn't say, have you seen the marfa lights? so now when people ask if i've seen the lights, i say, have you seen the lights? and most of them haven't. but the ones that have, they are the ones who are really

interested in knowing what the lights are. came here about three years ago, to marfa, and immediately fell for the landscape. i was stalking the lights every night. i think maybe i saw something like them what i wasn't paying attention. i do try very hard to find them. i'm neverquite sure. i got this poem, which is called western poem. purple clouds, my doubts. iridescent cream, my loss. and the street light, my reading. my appetite, my appetite. red striped sky, my confusion. bright yellow, grey sky, my otter. car lights, my commotion, telephone poll, my wishes. stop sign, my fear. black cloud, white sky, bliss. linking signals, my intentions. black mountains, too many suggestions. skipping lifelines, my attention. a young cowboy first saw the lights. the horns on your van, my defensiveness.

that old train, my dreams. that old train. still to come on the travel show: the incredible journey of one woman who has a passion for wild swimming. water is my domain. i'm happiest in the water. and we learn to ski the traditional chinese way. so stay with us for that. next up, we continue our series looking at incredible journey is happening around the world, as we visit snowdonia national park in wales. it's here where one woman's passion for swimming has led her to exploring this wild and unique landscape in a completely different way. it feels pure.

i don't think i've feel anything more pure than swimming. the water is my domain. i am happiest in there. over the last few years i have in exploring snowdonia national park, and wild swimming its 250 lakes. i have swum about 150 now. i am always searching for somewhere for a quick swim. if i can squeeze in a new lake then i will always go for that. snowdonia national park is a mountain range in north wales. it is a beautiful area to live in. the mountains here feel very rugged.

much more tightly packed. and in between that is where you get the lakes, and although they may be much smaller and a bit of a trek to get to, i don't know, for me, it makes it a little bit more special. i have always found since childhood, my mum was a swimmer. my mum passed away 11 years ago and i found grieving was very hard for me, so i think the time alone was part of it. i do obsessively swim now and i did not before, but i did not make a conscious decision to start swimming this way, it was definitely subconscious.

i have always had this, i call it a nervous anticipation in the tummy, but the nerves can be intimidation because sometimes the water is dark, you don't know what is inside, beasties or weeds, but that's an important part for me, is wanting to feel those nerves. i am not somebody who wants them to die down. sometimes i just want to be submerged up to my shoulders and just feel that feeling of the cool freshness on my skin

and, yeah, sometimes that is just enough for me. it is a time to leave everything behind and that's a huge part for me. documenting the lakes visually came about by being scared of what was underneath the surface. and i would take a camera under the water with me to capture what was — what was in there, and i would rush home to have a look, to see what i had captured, and discover that there was nothing, i never saw anything, but occasionally, i would get a glimpse of myself on the camera or other people i was swimming with, and there was a great beauty and grace in seeing people underwater. you are seeing the landscape for a totally different reason. most people are coming here to go walking or to hike to the top of mount snowdon or whatever. because i'm doing this, i have seen parts of snowdonia i would never have seen before. i have no desire to go to the top of anything any more, i — yeah, there is still so much to discover.

vivienne rickman—poole wild swimming in wales, and we will have more incredible journeys for you soon. to finish up though, we are off to china, which strangely for some has been described as the birthplace of skiing ever since cave paintings of skiers were discovered in the country's altay prefecture. i'm afraid that is all the time we have this week, but coming up next week... if you invite was lost in the post like mine,

ade visits windsor to experience ways to experience britain's upcoming royal wedding without heading to the church on the big day. don't forget, you can follow us wherever you are in the world byjoining is on our social media. all the details are on your screen right now. but from me, henry golding, and all the team here in alice springs, goodbye. hello there. yesterday we had a lot of cloud in the sky across much of england, thick enough to bring some rain as well. further north—west, showers developed through the day, but that cloud has been melting away as well. some passing showers in scotland, but a fine looking sunset here in 0ban. as the skies have cleared more over recent hours we have more pictures

of the full moon being sent to us, spectacular shots from people out and about under those clear skies. clear skies, yes, but a chilly start to the day. for the early risers, frost patches to look out for in the rural areas of scotland. not quite so cold further south under this zone of thick cloud. most areas of cloud could be thick enough to give us a few spots of light rain on and off through the day. the best of the early morning sunshine again through western areas, but slow—moving showers will form again, particularly in northern ireland. later in the day we will see a band of rain moving in from the continent, bringing some wet weather to end the day across south—east england, with strengthening winds here making it feel particularly chilly. that wet weather will continue to extend across south—east england and east anglia as we go on through sunday night. 0n into monday. we are going to get this area of low pressure moving up from the near continent. the rain gets more extensive and the winds get colder and stronger. this is what is in

the forecast on monday. heavy rain, a windy day with gales around the east coast, and it's going to feel cold, more like a february day than one in late april. so the wet weather is there. a bit of uncertainty as to how far west this band of rain will reach. there is the chance of seeing a few snowflakes mixed in with this and some sleet, mostly on high ground, above 200 metres of elevation. even that won't settle. it's mostly cold rain that will be falling, with those chilly winds. temperatures really struggling. highs in birmingham, five celsius. it is going to feel that cold. 0n into tuesday, that area of low pressure continues to feed cloud and bits of pieces of rain across eastern areas. another weather front moving in from the atlantic, bringing wet weather to northern ireland later in the day. in between these two systems the weather should be quite quiet on tuesday with some

sunshine around. chilly where it is cloudy with the rain moving in, and in the best of the sunshine, temperatures climbing at least up into double figures fairly widely. looking at the outlook over the next few days and the week ahead, you will be pleased to hear once we have got rid of that chilly weather and the rain to start the week, the weather should improve. highs of 19 in london as we head towards next weekend. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is nkem ifejika. our top stories: president trump confirms negotiations to set up his meeting with kimjong—un are under way — the talks could take place in may. and we are doing things that are

good, we will have a meeting of the next three or four weeks, a very important meeting. the denuclearisation of the korean peninsula, of north korea, denuke, denuke. tens of thousands return to the streets in spain after a court acquits five men of raping a teenager — convicting them of sexual abuse instead more mass demonstrations in armenia. the ruling party says it won't put forward a candidate for a new prime minister, to try to ease the crisis.
