there were other concerns, too, around the summit. john lambert was one of those left wondering about the environmental impact of the bbc�*s coverage: the bbc�*s climate editor justin rowlatt has, in the past, defended on this programme the need he sees to travel and take flights in the course of reporting on the environment. but he was also the subject of another complaint this week, regarding his appearance on air. this is the main conference hall where the leaders speak and as you walk around this truly vast convention centre,

you get an idea of the range of issues under discussion. anthony webb wrote to us, saying: it's not the first time justin rowlatt has caused some controversy by wearing jeans on television. he did so in the news at ten studio injuly and tweeted afterwards: well, it's clearfrom what we've heard this week that some viewers do consider the wearing of denim on screen to be a disgraceful lapse in standards. but if you think it's a refreshing, new casual approach, do let us know. the other big international event of the week was

the midterm elections in the united states. widely covered by different bbc outlets and throughout tuesday night and wednesday morning, the special programme on the news channel. it's election night across america. 50 states, millions of votes and an outcome that will be felt here and around the world. the control of congress is up for grabs with republicans looking to retake the house and the senate from the democrats. tyrone nelson contacted us on wednesday morning to say: and someone tweeting as flatv, thought the priorities used by the bbc online were mistaken:

but another viewer disagreed with those views, asking: russia announced on wednesday that it was pulling out of kherson. but the previous night, a panorama special had focused on another ukrainian city, mariupol, which was bombarded from the start of the war in march until it fell to the russians in may. woman speaks ukrainian.

the hour that followed was harrowing and powerful and was applauded by viewers such as richard prescott, who called it: and fran carrillo wondered: well, let's talk to the panorama correspondent hilary andersson, who is responsible for that film. hilary, it was a very powerful piece of television. there was no reporter or narration on that film at all. how and why did you decide to structure things that way? well, this was a very carefully thought through and deliberate decision right from the beginning of the project, because the whole idea was to tell the story of mariupol and the war

inside out, instead because, you know, every day, we watch coverage of tanks, of reporters talking, narrating with clips of individuals but sort of looking at the war from the outside. and what this film did was to go notjust to the people to allow them to tell their story, but to go right inside their heads and to tell the story of the war in an experiential way. for that to be completely authentic, we felt — our team felt — that they needed to speak in their own languages and that it would be better not to have any narration and just, let's listen to the voices of the people who lived through the siege of mariupol. as we know, it's been pretty much impossible to get access to mariupol for months now. so, how did you find the people involved? and how did you find the footage to tell the story? well, the project began —

i started working on it in march, when the siege was in full swing, and i started out trying to get a phone call through to people in mariupol — which was virtually, but not completely impossible at the time. i soon discovered, though, that people were not only getting out but you could zoom them. so, we then started to track down people who had fled the city and listened to them, and listened to their stories. and then there was a question of footage — a huge problem, because a lot of people — or almost everyone — had deleted everything they had shot on their phones. russians were checking people's phones as they came out, so it was a very real problem. people were scared and the word went round, "delete everything "if you're going to try to get out of mariupol". so, it was very, very difficult to get footage, but we did that by using software to retrieve deleted data from people's phones and also, not everyone deleted everything they thought they'd deleted, so there was footage and we were able to use that.

this is very much a ukrainian citizen's point of view, the whole film. can i ask how you squared that with the important notion of bbc impartiality? well, due impartiality, as you know, is a concept that applies across bbc coverage. this film is only one piece of our overall coverage. what we did was a very authentic piece ofjournalism in circumstances where we couldn't — of eyewitness journalism — and circumstances where independentjournalists couldn't operate in mariupol, as you know, which is now under russian control, and there is a lot of fear. people are even afraid to speak to western journalists openly. but we were not trying to do was litigate. we weren't trying to do a film which said, "is this "a war crime? "who did it? "who is responsible? " we didn't do any of that in this film. this documentary is about people's experiences and we set out to relay their experiences, and that's what we did. and, as we know, the result is quite distressing and powerful to watch. you yourself have worked

in a number of war zones, including darfur in afghanistan over the years. can i ask how it has affected you, dealing with this trauma, in mariupol? well, if you spend six months talking to people who have lived through mariupol and who have lost family members under the rubble and been extracted from the rubble themselves and who have nightmares about seeing young children who were — honestly, it's... this isn't about the journalists who cover it. it's distressing to hear their stories — yes, i have cried a lot over the last six months — but this isn't about me or our team. we are the conduit for people who went through this to tell their stories, and their stories are incredibly powerful because they wanted so badly to tell their stories because they wanted the world to know. and because the particular people we spoke to really and about what this war really means and what it really means to live through the decimation

of your city. hilary andersson, thank you so much. finally, this week saw the death of the pioneering election analyst sir david butler. one of the many ideas he had for transforming the bbc�*s coverage of politics was a pendulum device, shown in action here on general election night in 1959. and back in the studio here, david butler wishes to give a short session in swing. up here. i think it was 3.5 hours ago that bob mackenzie said that labour needed that swing — 2% or more — to win the election. well, at the beginning of the night, it was all over the place, one to the other way made us think we might hesitate. but after 30 results, it has settled down, and it has been staying steady now. the average swing over the whole country, 1.3% improvement of conservative position over labour. the swingometer has become a little bit more high—tech in the years since, as used

by the likes of peter snow and jeremy vine, but the ground—breaking principle remains the same. among the tributes paid to sir david butler was this from the bbc�*s current election analyst, sirjohn curtis. thank you for all of your comments this week. if you want to share your feelings about what you see or hear on bbc news on tv, radio, online and social media, e—mail. or you can find us on twitter. you can call us. and do have a look at previous interviews on our website. that is all from us. we'll be back to hear your thoughts about bbc news coverage again next week. goodbye. hello. this exceptionally mild weather is producing some remarkable temperatures — 19.5 degrees

celsius at myerscough in lancashire on friday, 19.1 at lossiemouth in moray. so, what's going on? we've got a big dip in thejet stream to the west of the uk and it's around the base of this dip we're drawing up close to the azores some of this exceptionally mild airourway. so, temperatures are so far above average for the time of year. in fact, on thursday night, provisionally, according to the met office, both scotland and northern ireland had their warmest november nights on record. and, of course, climate change is notjust about those big, headline—grabbing daytime temperatures, it's how far we keep warmth overnight as well. very windy on friday across northern areas and yet more rain in the highlands — in fact, achnagart, since monday, has had 258 millimetres of rain — some months' worth of rain in a week. a lot of that rain has gone this weekend, keeping the very mild weather. not as windy, though, and that does increase the risk of seeing some mist and some fog. and actually, a cooler start to the day for saturday. in fact, under the clear skies in north—east scotland, low single figures in some

spots, six or seven degrees in east anglia. with a lot of low cloud and mistiness across a large part of wales and england, northern ireland seeing some overnight rain clearing away as that trundles north across scotland. behind it will brighten up, though. still the cloud thick enough in a few spots for a bit of drizzle. some eastern parts of england may stay with some low cloud, whereas for much of england and wales, it will turn sunnier. a cooler day but still very mild for scotland, northern ireland, northern england. through much of england and for wales, we're talking 16 to 18 degrees celsius. and, yes, those lighter winds, allowing more in the way of low cloud and mist and fog to form as we go overnight and into sunday morning. thick enough for some drizzle in places, particularly through eastern scotland, central, eastern parts of england. a milder start to the day on sunday. so, for remembrance sunday, then, a grey, misty, murky start in many places and although for many places it will brighten up and get to see some sunshine, there'll be some spots from eastern scotland and down through central and eastern parts of england that could well hold on to some grey conditions, maybe quite

widely into yorkshire. another very mild day out there. wind freshening in the west, some rain to northern ireland as we go on into the evening and the main feature of the weather for the week ahead is that temperatures are going to come down much closer to average. spells of strong winds and heavy rain at times.
