coming up: the travel show comes from hong kong to see how the famous pink dolphins are being affected by the fast pace of development. before that, time for a look at the weather and thomas, there has been rain at lord's and thomas, there has been rain at lords and sunshine at royal birkdale. tell us more. a bit of everything. some rain around yesterday and more today. chance of downpours almost anywhere in the uk. let's look at the forecast for the middle of the afternoon. rain across the south, rain across the north—east and in between, sunshine and showers. some already turning thundery for example gci’oss already turning thundery for example across wales and the south—west. take a brolly today and expect rain. rain and cloud across eastern areas

tonight. western parts of the uk, it is clearing up and there will be a big contrast between the east of the country and the west. the east will be cool and breezy whereas western areas will enjoy a fine day. tomorrow has a stunning day on the way for the south—west of scotland. temperatures in glasgow could be in the mid—20s. a beautiful day there in south—west scotland. this is bbc news. the headlines... some of the bbc‘s most high—profile women have written to the director general, calling on him to correct gender disparity in pay. a 20—year—old man has died after being confronted by a police officer in east london. cctv footage has emerged of the officer wrestling the man to the floor of a shop in hackney. prince william and prince harry have spoken of their regret that their last conversation with their mother was a "desperately rushed" phone call. health secretaryjeremy hunt has

described the abuse of staff at great ormond street hospital, where baby charlie gard is being treated, as "totally unacceptable". blood donation rules for sex workers and gay men are being relaxed in england and scotland after improvements in the accuracy of testing procedures. 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 use 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 numbers 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 2,500

hectare marine conservation park in northern lantau 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 the 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 2,000 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 the waters is near the mouth of the river so the sea isn‘t too salty.

this is their usual habitat, this is what dolphins like. for a while 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 2a 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. —— who work at these places. 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? 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 adds 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, wherever 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 to 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 did nose to 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. 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. shaoxing wine is 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. we‘re trying to get a bit of colour. then we‘re going to add, this is really nice, this is the chrysanthemum butter. that‘s going to add a really nice floralness to the fried rice. we‘re layering the flavours into the chicken. just a little bit more of that shaoxing wine. so this we‘re going to

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. it isn‘t traditional for this dish but it really adds a nice floralness. we got this inspiration from having snake soup in hong kong. the chrysa nthemum also

represents chicken feathers. and then, table—side, we garnish with the soup. so this is our version of yellow wine chicken. refined cantonese food with super comfort levels. 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. the weather is very changeable today. a risk of downpours. a nice picture from worcestershire. blue skies and cloud. this is the satellite picture so rain across southern areas. also cloud and rain across eastern parts of scotland. not a pretty picture anywhere from —— around newcastle. in the midlands, a case sunshine and showers. let‘s look at the weather around five o‘clock in the afternoon. looking pretty good

across cornwall, devon and western parts of wales. the showers would have moved into south—western —— south—eastern parts of england. that mixture of sunni stars and showers. the best of the weather today across northern ireland and parts of scotland. a bit like yesterday. whether better in the highlands and western isles. what can we expect tonight? clarrie rain across western areas but the rain will be mostly light. some western areas enjoying clear spells. tomorrow will be a different day for many of us. the low pressure is pulling away so taking the bad weather with it. western parts of the country are really starting to dry out. it big contrast in the weather compared —— if you compare hull to belfast. even

in the mid—20s in glasgow. wind of the north sea coast and cloud and spots of rain. the best day of the week overall will be tuesday. temperatures getting up to 20 degrees throughout yorkshire, even. and wednesday, outbreaks of rain coming in off the atlantic so a wash—out for some of us. from thursday, it will dry out to an extent and sunny spells and showers. so changeable week ahead. the wettest day will be on wednesday and then rather cool for most of us. then a sunny spell tomorrow in glasgow and western scotland. have a great day. this is bbc news. i‘m shaun ley. the headlines at 2pm. more than a0 of the bbc‘s best known women broadcasters have written to the corporation‘s director—general demanding he "act now" to deal with the gender pay gap. the point of the letter is to say in 2020 it will be fifty years

since the equal pay act of 1970 — tony, we all love the bbc we want to carry on working for it, i think we need to do things a little bit quicker. a 20—year—old man has died after being confronted by a police officer in a london shop. new insights into the relationship princess diana had with her sons regrets about a final phone call. william harry open up in a documentary on the 20th anniversary of her death. international trade secretary liam fox has given his backing to a two year transitional deal with the eu after brexit. frankly i‘ve waited a0 years to leave the eu,
