the decline of the bewick�*s is being blamed in part on their wetland habitat being destroyed. climate change is also altering their migration routes. longer summers in the russian arctic and warmer european autumns mean the swans don't have to come as far as slimbridge to find winter feeding grounds. it's just one lake and a single species, but chronicled over 60 years the bewick�*s fate is a telling snapshot of our rapidly changing planet. jonah fisher, bbc news, at slimbridge. time for a look at the weather. here's louise lear. great weather for webbed feet, i think, is the best description. it's really trying our patients at the moment. it seems to have been relentless. a lot of the countryside looking like this, fairly flooded.

there are literally hundreds at the moment of flood warnings and i suspect we will be adding to those this evening across southern england, as more heavy rain is expected. so keep watching the forecast, tune into your bbc local radio station for updates, but it's this swirl of cloud that's starting to push on from the south—west and this will bring a spell of wet weather across southern england during this afternoon and then it's going to push its way east. elsewhere a case of sunny spells and scattered showers, blustery across the northern isles, here are a frequent rash of showers and it will be on the cold side, two or three degrees at the very best but generally for most of us we are looking at 7—9 c. let's zoom into the rain. on top of the rain we have gusty winds through the channel. the jersey met has issued for red warning for gusts in excess of 60 miles an hour. it's pushing through at pace, a couple of inches falling on saturated flooded areas could

have an impact. it moves towards east anglia, across east lincoln and the midlands through the night. a scattering of showers continues to the east where we get breaks in the cloud we could see patching mist and may be some frost, but mist and fog more of an issue. tomorrow, the front plus system moves away but this little front here is going to enhance some showers across the far north and east of scotland league and england still. there will be some sunny spells once that mist and fog lifts out to the west, a few scattered showers along coastal areas because of the direction of the wind and still those temperatures generally between 6—9 degrees, but if you are watching countryfile earlier on this week i did promise you something a little bit quieter and a little bit drier, and he has that high pressure starting to move in. what it's going to do is it means the blue colours, the cooler air, will start to dominate. nothing particularly substantial. it could be a shock to

the system as it's been so mild. what will also be a shock is look at this, there is no rain on this chart for the next four days. fine, dry, yes, we will be chasing cloud amounts around so not that much in the way of son from time to time and we could have a problem with early morning frost and fog. that's it, something to look forward to. thanks, louise. and that's bbc news at one. now it's time to join our colleagues for the news where you are. hello and welcome to sportsday. cool hand luke humphries becomes world darts champion, but teenager luke, the nuke, littler brings a whole new audience to the sport. encouraging signs in defeat for emma radacunu as she continues her comeback from injury. and injust a day and half

an extraordinary tournament then that has really caught the imagination of the british public in a way the sport of darts hasn't done for years. matt porter is the chief executive of the pdc, he told jane dougall that humphries is a worthy champion of a tournament that has broken all manner of records. remarkable, as you say, it was a tournament that smashed all records and surpassed anything that we have been able to deliver before but loo countries overcoming so many personal challenges to get to where he is, he's won four of our last five major events and for him to be crowned world champion —— luke humphreys. it is a pinnacle of that. he richly deserves it. one of the reasons why so many people were tuning in was because of the phenomenon that is luke littler. how much is he impacted the spotted such a young age? he much is he impacted the spotted such a young age?— much is he impacted the spotted such a ounu ace? , ., a young age? he has been remarkable. what a narrative _ a young age? he has been remarkable. what a narrative he _ a young age? he has been remarkable. what a narrative he is _ a young age? he has been remarkable. what a narrative he is generated - what a narrative he is generated over the last two are 23 weeks. he just wanted to go out and win one match. as 16—year—old, it was a step into the unknown for him to go on and play in such a major

environment. he delivered time after time. we took it all in his stride. notjust from what he is achieve for himself, but what he is achieve for the sport, opening the doors for a new demographic, there are hundreds of kids out there playing organised darts at academy level from the age of eight upwards, so i'm not saying there are plenty more luke littlers out there, but there is plenty of talent and may be future generation of champions. talent and may be future generation of champions-— of champions. humphreys said last niuht he of champions. humphreys said last night he was _ of champions. humphreys said last night he was so — of champions. humphreys said last night he was so glad _ of champions. humphreys said last night he was so glad he _ of champions. humphreys said last night he was so glad he was - of champions. humphreys said last night he was so glad he was won i night he was so glad he was won because he said not many people can beat luke littler in the future. what do you see in this young youngster�*s future? you what do you see in this young youngster's future? you couldn't back against _ youngster's future? you couldn't back against him _ youngster's future? you couldn't back against him not _ youngster's future? you couldn't back against him not winning - youngster's future? you couldn'tj back against him not winning the tournament after tournament, but in the same way there may be thinking they have had that nose put slightly out of joint they have had that nose put slightly out ofjoint by a 16—year—old new kid on the block. so i think competition will be the spot in the words of humphreys, it was his time

last night, it was his night and he took his opportunities. away from the darts, preparations for this months australian tennis open are well under way. britain's emma raducanu, who this week was awarded a place in the main draw despite a difficult year of injuries, has been in action this morning. she won first set against second seed elina svitolina in the asb classic in auckland, but was eventually beaten two sets to one. she has every reason to be delighted with the way she played and, yes, there will be disappointment that there will be disappointment that the third set was so one—sided, but there were two hours and 15 minutes on the clock when the third set began. to be realistic, you have been out since april, three minor operations, then you are going to tire in the first set of a match of the quality and physicality. meanwhile, great britain has gained an extra competitor for next week's australian open qualifying competition. oliver crawford, who has two

parents from birmingham, has now switched his nationality from the united states to britain. the 24—year—old from south carolina, with a world ranking of 215, immediately becomes the british number 9. now, when you think of arsenal football club, you might think of great players like charlie george, ian wright or thierry henry. their iconic red shirt probably also springs to mind. but this weekend, when they host liverpool in the fa cup, the gunners will be wearing all white. its part of the clubs no more red campaign — an initiative aimed at tackling knife crime in london. 18 teenagers died as a result of being stabbed last year. iam i am obviously in a fortunate position where i have become a footballer and now, i was that young kid once that looked up to people like myself, and it is an honourfor me to be able to help young kids, to talk and use my voice to show that i was a youngster once and i've been

in top positions as well. for me it is all about youngsters growing up, being happy, feeling comfortable in their environment and living a good life. that is the main thing. you only get to live once and if you get a big opportunity, take it with open hands are so many doors can open up. kevin sinfield will leave the england rugby union coaching set—up later this year. he has been the defence coach, but as head coach, steve borthwick reshuffles his team after the world cup, sinfield has moved to coaching individual skills and kicking. felixjones, who joins after winning two world cups with south africa, has been confirmed as the new defence coach, with former all blacks coach andrew strawbridge also joining the team. to cricket, where india have beaten south africa in what is the shortest ever decided test match. none of the drama of the opening day, when 23 wickets fell. india today knocking off the required runs in cape town with 7 wickets to spare,

injust a day and a half. they probably have got time to play that all over again and still win within five days. you can get all the latest sports news at from the bbc sport app, orfrom our website — that's bbc.co.uk/sport. from me and the rest of the team at the bbc sport centre, goodbye. breaking news, rishi sunak said it expected to have a general election in the second half of the year. speaking during a visit to mansfield, in nottinghamshire has appeared to rule out holding a general election in the spring. let's hear what he had to say. it is a new year. it is also going to be a general election year? yes! my working assumption is we will have a general election in the second half of this year, and in the meantime i have got lots that i want to get on with. this saturday, we will be introducing a significant tax cut for millions of people in work,

worth on average £450 for an average worker, because we have halved inflation and we want to keep managing the economy well and cutting people's taxes. and i want to keep tackling illegal migration. we cut the number of arrivals last year by over a third, but we have got more to do and we plan to get the rwanda scheme through parliament and up and running. so i have got plenty to get on with and that is what i am focusing on doing, delivering for the british people and it is great to be talking to people here in the east midlands about that progress today. just to clarify, you said the second half of the year. so you are ruling out the may election? i said, look, my working assumption is there will be an election in the second half of this year because in the meantime i have got lots i want to get on with, and that means cutting people's taxes this saturday. that is a tax cut worth £450 for an average person in work. we can do that because we have halved inflation. and i want to keep going, managing the economy well and cutting people's taxes, but i also want to keep tackling illegal migration. last year, we got the numbers down by a third and now we need to get our rwanda scheme through parliament, up and running so we have a full deterrent,

and that is how we are going to really solve this problem once and for all. so i have got lots to get on with and i am determined to keep delivering for the british people. it has been great to be talking to people here in the east midlands about our progress today. the bbc�*s political editor, chris mason, has speaking to the labour leader, sir keir starmer, he gave his reaction to the prime minister's election date comments. we are ready for a general election. i think the country is ready for a general election, to turn its back on this decline and usher in the hope and change that a labour government can bring. the prime minister is now hinting, without setting a date, that it might be later in the year. what is he hiding? why can't he set a date? you know, squatting in downing street for months on end, dithering and delaying when the country wants change, what is he hiding? and you can see the full interview with sir keir and our political editor, chris mason, at five o'clock this afternoon here on bbc news. live now to our political correspondent, harry farley.
