this is bbc news. the headlines: the white house press secretary, sean spicer, has resigned, reportedly because he was unhappy with president donald trump's appointment of a new communications director. the new appointee, anthony scaramucci, denied there had been tensions over his appointment. the world health organisation has said the cholera outbreak in yemen is out of control — with over 300,000 people affected. the country has been racked by civil war and an intervention by saudi—led forces for the past two years. asa as a result, a government health services have collapsed. the victim of an armed robbery in which oj simpson was jailed has told the bbc why he gave evidence at the former football star and actor's parole hearing on thursday. demonstrations have been taking place in the polish capital, warsaw, against a bill to replace supreme court judges —

seen as a threaten thejudiciary‘s independence. earlier, we spoke with dr malgorzata bonikowska from the polish think tank the centre for international relations. the situation is really serious now and it is very sad because it seems we are losing the ability to discuss things. it is not only among politicians, it is also among people. polish society is very divided, and this division now goes much deeper. it seems like it is one step too far. no one says the ruling party doesn't have a right to propose the changes, or implement reforms, but the way they are doing this and what they are proposing is very controversial and needs wide political debate. but the government is not open to that. so the question would be how are we able to build the community and how are to be able to live under the one roof, if we just want to accept one point of view and polish society as a very difficult and complicated history.

there are people who think many different ways here. not all the people support the party. so the question is are we still able to make a dialogue to discuss. by the way, this is exactly why people go out in the streets to protest and this is really serious. the protests are massive all over the country, because we are very much for the dialogue — this is how we started our transformation process. if you remember, in the late ‘80s, even before the berlin wall collapsed, we had round table discussions — the solidarity movement and the communist party. after 26 years it seems like this furniture is not needed, and that is why people are really worried and frightened. because we understand very well that society is divided, we need to discuss the things, there are people who think in many different ways here, so only the way of dialogue can save us. otherwise we are heading nowhere. now on bbc news, it's time

for the travel show. coming up on this week's travel show. oh, no, 0k! three o'clock, three o'clock, three. i'm in hong kong to find out how their famous pink dolphins are being affected by the fast pace of development here. we meet one of asia's top chefs to get a new take on traditional cantonese cuisine. we're in northern canada to discover how to use an iceberg to make a cup of tea. i actually know him! and going underground in london, we meet the people who help to keep the trains running all night. this year marks the 20th

anniversary of the handover of hong kong to china. since 1997, the pace of development here has been rapid, as beijing pushes ahead with its transitional "one country, two systems" formula. a plan that will eventually see hong kong merge economically and politically with the communist mainland, in 2047. but environmentalists fear that one of hong kong's most iconic creatures may not survive that long. the pink hong kong dolphin

was actually a symbol of the handover of hong kong from british back to chinese rule 20 years ago. but now, their future is under threat. the dolphins‘ vivid pink colour isn't caused by pigmentation. it happens as blood vessels expand and contract as a result of thermo—regulation. it's a system the dolphins used to control their body temperature. the dolphins are meaning good luck in chinese culture and also they go beyond hong kong border to chinese waters, so it's sort of a unity between hong kong and china back in the handover days. so it's sort of a symbol of unification between hong kong and china. they're also a good luck and energetic symbol. unfortunately, you know, their numbers are in decline. so it's not such good luck now. figures from hong kong's fisheries and conservation department show

that the number of pink dolphins here have crashed, from 188 in 2003 to only 65 in 2015. and although nobody is exactly sure how accurate that figure is, there's no doubt that numbers are falling. i've been coming to hong kong for around 20 years now and i'm ashamed to say i had no idea there were dolphins in the waters here. but of course you won't find them in victoria harbour where the tourists are. to be in with a chance of seeing the dolphins you have to leave hong kong island and go west towards the airport. land reclamation, population growth and pollution are all being blamed for destroying the dolphins‘ habitat. huge new infrastructure projects like this new bridge and tunnel

to macau may be good for the economy but environmentalists claim it is playing havoc with the dolphins‘ natural environment. the hong kong government has announced it will create a new 2500 hectare marine conservation park in northern waters to help counter the effects of building another runway at the airport. the conservationists say that the marine park is in the wrong place and won‘t help the situation. so, when we go out to sea we use a long lens to take high—quality photos, as you see, because there is the information we used to identify the dolphin, just like the fingerprints on your hands. like this one, there is a round tip and a big notch. so from this one we can know exactly this individual has been seen, when and where. we need at least 2000 dolphins to sustain the long—term survival. but in the current situation,

no matter how many times we run the simulations, the population is doomed to extinction. so that‘s a very worrying scenario. what needs to be done? what we are proposing is, protect what is important to the animals first. now, it‘s notjust about quantity, about how many kilometres square of habitat is being protected but also where it is protected. those core areas should be highly prioritised areas to be protected in terms of stopping the development, lowering the fishing effort. basically reducing the pressure on the animals. so, give them a place to survive. well, determined to try and see some pink dolphins, i headed to lantau with an advocacy and ecotourism group called dolphin watch, who have been working to promote marine conservation

here for two decades. many of the dead ones that are found every year are juveniles or babies. i‘m going to show a dead dolphin. if you‘re very sensitive, then you may wish to not look. just looks like it‘s sleeping. so, what could have happened to this dolphin? 0k, there‘s no crisscross scarring, it didn‘t drown in a net. what are we going to see today? are we guaranteed to see dolphins? no, no. it‘s a 97% success rate and if we don‘t see any then people will get to go again free, assuming they have the time here, but that‘s a pretty rare occasion because after 20 years of doing this we have a pretty good idea where the dolphins will be, given the wind and rain and time and tides, but they are wild animals so we can‘t make promises. you‘ll see lots of garbage, lots of concrete, lots of boats and hopefully lots of dolphins but, you know, i have to lower expectations because some days it just doesn‘t happen. i really hope we see a dolphin.

the conditions are in our favour, it isn‘t too windy and where we are now in these waters is near the mouth of the river sowed the sea isn‘t too salty. this is their usual habitat, this is what dolphins like. for awhile while there‘s nothing and then as we head into the western waters of lantau island, we suddenly get lucky. oh, gosh, there‘s one over there! oh, i missed it. got to be quick. it‘s a pink one, is he going to come up again? yep. yep. yep- oh, no, no. three o‘clock, three o‘clock. 0k, over there! people love concrete here.

where is the tipping point where you say the dolphins are no longer sustainable, if you like? and even if they are, the gene pool is going to be shrinking with fewer and fewer dolphins so, by the time you list something as endangered, it‘s quite often too late. as a cosmopolitan city which is very wealthy, we have the resource to make a balance between development and conservation of the environment. we can do both. we have to strike a balance. we can have all the development that we want but at the same time we also need to build up the capacity for the dolphins to withstand all the threats. we use the dolphin as the mascot, the symbol of the handover so it‘s our responsibility to ensure that they will be here for a long time, notjust for us, but for the next generation and future generations to come. time now for the last in our series

of films looking at the people who keep london moving, long after most people have gone to bed. and this time we meet latoya, who works overnight at one of the capital‘s busiest tube stations. my name is latoya raymond and i‘m a customer service assistant here at the london underground. and i work for the infamous oxford circus station. since the launch of the 24—hour night tube last year, we actually run 2a hours on fridays and saturdays. my role begins the minute you walk through the station and if you need assistance along the way, anywhere, i‘m here. that‘s what we‘re here for.

that‘s fine, if you want to touch your 0yster card. 0n there? yeah, that‘s it. there you go, my love. sound result that for you. and that‘s done. thanks so much. you‘re welcome, take care. at night, this is where oxford circus comes alive. central london comes alive during the night. everyone‘s coming out, everyone is going out and having a great time, especially on fridays. you finish work, you don‘t want to just rush home, so they take advantage of the nightlife, they take advantage of the pubs, the fact that we have 24—hour services. people enjoy it and the atmosphere is always amazing. it‘s great. i am a people person, i‘ve always been a people person. so you are the actual monopoly man! it is fun, it is absolutely fun. so we've done all the 26 pubs.

0n the monopoly board? yes. they come down the stairs singing. wejoin in! i don‘t know how you‘re still standing. take care. along with persons that are going out, having fun, going to clubs, we have persons who work and these pubs. i actually know him. i‘m sorry, i have to run and hug him. now they can just come through and go home. if you can imagine working throughout the night and then having to wait another two hours for the trains to start running, it‘s not nice. we go out as well, you know. we aren‘t all about work, work, work. we‘re a great bunch, we get on. this is a family. where did you go?

aw! yeah, there is no more trains for the bakerloo. at nights, at the moment, we only have five lines that are running. so the problem with that is, most persons, they aren‘t quite aware of what lines are running and how to get home. so again, this is where knowing the job, knowing the stations and knowing how to help persons. we have all the resources we need to make sure that we can get everyone home. so now that the last bakerloo line has left, it‘s time for us to shut the gates so no—one else can enter. they can always use the northbound or southbound victoria line or the central line if they need to get home, but for tonight, there‘s no more bakerloo line trains.

stay with us, because still to come on this week‘s show — coming up next, we eat out here in hong kong with one of asia‘s top chefs. chrysanthemum is not traditional for this dish but it really as a nice floralness, and we got this inspiration from having snake soup in hong kong. and head to the far north of canada to meet the local people who survive some of the harshest winters on earth. the travel show — your essential guide, whether you‘re heading. up next, here‘s another in our series of films to mark

canada‘s 150th birthday this year. and this week, we‘re off to the far north of the country to meet some of the people who live in the town of qikiqtarjuaq, inside the arctic circle. well, to finish off this week, we‘re heading back to hong kong — a melting pot of cantonese and western cultures and an amazing place to visit if you love food. may chow was voted asia‘s best female chef earlier this year and she is building a reputation as the driving force behind a new generation of chefs who are specialising in what‘s being called neo—cantonese cuisine. we were lucky enough to go behind the scenes at her happy paradise restaurant in hong kong to watch her cook one of the most popular dishes. today, we‘re going cook for you a three yellow wine chicken. so basically it‘s originally a hong kong dish but at happy paradise we do neo—cantonese

food, so we‘re going to do it with more cantonese techniques, having a bit more refined. what we have here is a local breed three yellow chicken. we‘ve already slow—cooked it. for the breast, we‘ve cooked it at 58 degrees. for the thigh, we‘ve cooked it at 83 degrees. and for the feet, just a little garnish, because chinese people don‘t notice the tail first. we‘re going to do a rice on top with seasonal mushrooms, a little bit of chrysanthemum butter just to lighten it a little bit, to make it more floral, and it‘s going to be finished with a shaoxing broth. so we‘re going to put the chicken in. it‘s already fully cooked, so what we‘re really doing is reheating it. we‘re going to start the broth. this broth is shiitake—based. you can really smell a lot of shiitake mushrooms in there.

we also have shaoxing wine. and of course shaoxing wine is like, you know, the most commonly used cooking wine for chinese people but when you cook it with something like yellow wine chicken, we‘re quite aggressive with adding the shaoxing wine. we‘re going to stir—fry the mushrooms. in cantonese terms, it‘s actually called chicken mushrooms, so that‘s why we‘re adding it as well. so we‘re trying to get a little bit of colour on. then we‘re going to add — this is really nice, this is the chrysanthemum butter. so that‘s going to add a really nice floralness to the fried rice. so we‘re kinda layering the flavours into the chicken. just a little bit more

of that shaoxing wine. so that‘s where we‘re gonna put aside for garnish. just going to chop the chicken. the chicken should be ready. so we‘re going to take the chicken out. now we‘rejust going to ladle the rice on top. now we‘re going to garnish with a bit of chrysanthemum. chrysanthemum is not traditional

for this dish but it really adds a nice floralness. we got this inspiration from having snake soup in hong kong. the chrysanthemum also represents like chicken feathers. and then, tableside, we garnish with the soup. so this is our version of yellow wine chicken. £57.75; ez":*zzz 11-5» ——— — -,-,,,,, f”— well, that‘s all we got time for in this edition of the programme. coming up next week — as pakistan prepares to mark 70 years of independence, we go to karachi to get a taste of life in the city. there‘sjust so much more to karachi than we know.

it has depth in terms of the people who live here, the cultures that exist, the lifestyles, the architecture, there‘s so much to see. well, i hope you canjoin us for that if you can. don‘t forget, if you want to join the rest of the travel team on theirjourneys, in real—time, you can sign up to us on our social media feeds. all the details should be on your screen now. but until next time, from me, carmen roberts and the rest of the travel show team here in hong kong, it‘s goodbye. hello and welcome to the weekend — although you may view that

as a somewhat hollow greeting once you have seen the forecast. some really very wet weather on friday in south—west england and wales in particular. but that transferring further east around this low pressure, which is still a player in our weather going to the weekend. not a washout. more of a sunshine and showers picture. but some of those showers will be heavy. some sunshine in between, and after a really windy day for some of us on friday. over the weekend, it is still breezy, but the winds are looking lighter. showers could be gusty. this is what it looks like for early risers. showers move in towards south—west of the uk, and band of rain pushing away from the uk but still there in northern england and southern scotland. breezy picture in northern scotland. but north—west scotland should fare well throughout the weekend. northern ireland picking up the odd shower here and there. quite wet across parts of northern england, the further north you are. here is a drier, brighter slot

across much of wales and down towards south—east england. already, at this stage of the morning, a few showers popping up in south—west england and south—west wales. outbreaks of rain affecting parts of eastern england, but beginning to push away. so on through the day. where we start with sunshine, showers build. where you start wet, it may ease. throughout north—west scotland, it will stay dry, breezy, but warm in, with some sunny spells. one or two showers in northern island. you could catch a shower across southern scotland into northern england. it could well be torrential and thundery. the risk of hail, too. a rumble of thunder maybe to the south. could be a lot of rain to come. going to the evening, some of the really heavy showers to fade. could be, compared with friday, a quieter day at the open golf at royal birkdale. fewer showers around, but on sunday still some wet weather as we go into the final round.

so this is how sunday is shaping up. again, it is reallyjust sunshine and showers. maybe more of us, on sunday, escape the showers. temperatures through the weekend in the high teens, low 20s for most us — close to average for this time of year. as we go into monday, this system pulls away. it may have some lingering cloud and outbreaks of rain for eastern parts of england, but for monday and tuesday, for most of us, it is looking like a quieter story. briefly high—pressure and some fairly warm sunny spells coming through. hello. this is breakfast, with naga munchetty and charlie stayt. a big rise in the number of children declared homeless. councils in england say nearly a thousand each month are being forced into temporary accommodation. the government says it‘s taking action to tackle the problem. good morning.

it‘s saturday the 22nd ofjuly. also ahead: people who fly drones will have to pass safety courses and register their devices following concerns over the danger they pose to aircraft. white house spokesman, sean spicer, explains why he‘s stepping down from the job afterjust six months. ijust think it i just think it was in ijust think it was in the best
