a new warning from the united nations that time is running out to stop temperatures rising and a climate disaster. the un says global emissions need to fall by more than 7% every year over the next decade to stop warming by more than 1.5 degrees. three senior figures in malta's government have stood down, and angry crowds have booed the prime minister, as police step up their investigation into the murder of the investigative journalist daphne ca ruana galizia. a report published in the us shows death rates among young and middle aged people have been rising over the past decade, driving down overall life expectancy. thejournal of the american medical association shows the highest relative jump in death rates was among people aged 25—34, rising by 29%. he's a builder, she was until last

week a shop worker, but lenka thomson has given that up after she and her husband steve scooped 105 million pounds in the euromillions lottery. the couple from west sussex have 3 children. they say they were stunned when they realised what had happened. duncan kennedy went to meet them. cheering bubbles amid the disbelief. steve and lenka thomson with the smiles of super winners and the cheque for £105 million. i believe that's mine. it is indeed, and the couple still can't believe what's happened. it's life changing. it's life changing for... not just for us, our family. the family... our friends in the community. yeah. definitely. we are going to do a lot of good with this. lenka has a job in a grocery store, steve is a builder, and he went back to work after his win.

still had to go and paint a ceiling. so, why would you painting the ceiling? because i fell through at the previous week insulating someone‘s loft. the couple say they are going to be sensibly generous with their new pot of riches. richard and emma watson on £52 million, ronnie wood with £85 million, and gareth bale on £91; million. steve and lenka say the priority now is to move house so their children don't have to share bedrooms. while lenka has already given up herjob in the grocery store, steve says he won't be letting his customers down, and he'll carry on building. for now, it is carry on celebrating. a pre—christmas present for a couple now with a gift to spread their good fortune to family and friends. duncan kennedy, bbc news, west sussex. now on bbc news, the real derry girls. derry — or londonderry. famous for its murals, notorious for its troubles,

and now celebrated in the television series derry girls. i've been talking to the real derry girls, who, like their tv counterparts, are gutsy, funny, and brave. i'm sinead, i was born in the bogside in 1981. i am the only protestant in the derry girls. they couldn't have the bus across the street like the ira wanted. they were going to shoot them. i am 100% a derry girl. i get quite a lot of stick, that's why i love them all! a cousin of mine and his wife and child were injured in the omagh bombing. my families experienced the troubles, and his cousin was murdered on bloody sunday. that was the worst experience we had during the troubles. until lyra.

derry has been part of my working life for almost half a century since i first set foot in the city in 1972. on that dreadful day that became forever known as bloody sunday. when you think about bloody sunday, there is one particular image, i think, that comes to the mind of a lot of people. it is the one with the bishop and some men were carrying jackie. and the man with the cap behind the bishop, that is my father. liam bradley. it was on that day paratroopers shot dead 13 innocent civilians taking part in a civil rights march. it was my shocking initiation into reporting for conflict in ireland. the painful legacy lives on.

i think you would have to go far to find a family not touched by the troubles during this time, especially because of bloody sunday. it stretched and reached so many homes. with the fight for decades, to have innocent people's names cleared. few families in derry‘s tight—knit catholic community remained untouched by the so—called troubles. loved ones ended up dead. fathers and sons in jail. i first met my dad in the long kesh visitors room. i have memories being 3.5 years old there and he always gave me a bar of chocolate. so he was the man who gave me bars of chocolate. i do remember being in the kitchen and listening to the bangs out the window and hearing my granny saying prayers, throwing me under the table. i remember the bangs as well. that was the guy on the run from the police. it was here in derry that the seeds of the hard—won peace were sown.

this is derry‘s peace bridge, it was opened on the good friday agreement in 1998. it was the symbol of a bright new future not only for derry but the whole of northern ireland. that future is now overshadowed by brexit and the threat of violence from dissident republicans. it was the so—called new ira that murdered journalist lyra mckee just over six months ago. she had become part of the real derry girls with her partner, sara canning. for the group, this photo is very special, because one of those watching the television is lyra. this is the youth club. we had all gathered in here and we were watching i think it was the first episode of derry girls. all members of the group, bar one, are part of derry‘s lgbt community. they are all incredibly close and supportive of one another.

lyra and her partner were warmly embraced and soon lyra became an integral part of the band of sisters. she was funny, smart and intelligent. she was just a bundle of energy and she had a really infectious laugh. we joked about retirement homes when we were 70 or 80! all waking up with dementia together. i really fangirled her. i really did. she was brilliant. she always got us together and it was her organising parties and saturday nights and things like that. she clicked with us all so well from the start. i think her moving to derry cemented the fact that she was in the derry girls club. definitely. before she came to derry, lyra had already been recognised at the age 01:14 as a talented young campaigning journalist. even then, a rising star. she was passionate to address the alienation of young people.

it showed me what i can do and it has mapped out my career for me. i know this is my vocation and just what i want to do. what she wrote was so pertinent. lyra talked about the post—ceasefire babies. there was so much hope at the time, when the good friday agreement was signed, there was so much hope for change, that there would be massive change but there has been nothing but struggle and fighting over the last 20 years, albeit in a different format in stormont. one of the things she wrote, we were the good friday agreement generation, destined never to witness the horrors of war but reap the spoils of peace. the spoils never seemed to reach us. and that article — it spoke to me so much, before i even met her. in the north—west, we haven't seen the spoils of peace. the creggan estate is one of the most deprived areas in the united kingdom.

its poverty providing the soil in which the dissident new ira has been able to grow. it was formed in 2012, and followed four years later by the hard left wing, saoradh — meaning liberation. paddy gallagher is their spokesman in derry. this is a poster they have put up? yes, it highlights the message that states this band have rebranded ruc. it is basically psni in a different guise. a lot of people in the area and republican areas are opposed to british crown forces. the police? they do not trust them or see the need for them.

just over six months ago, relying on intelligence, police searched a house on the creggan for explosives. there were concerns an attack was being planned. none was found. a riot broke out. lyra was standing by a police land rover, covering the events as a journalist. a gunman opened fire at police but killed lyra. i was there, i saw lyra fall and land on the ground. i did not believe even right up until arriving at the hospital that she had been shot. i could not believe that's what happened in creggan. saoradh‘s paddy gallagher was also in the vicinity on the night of the riot. a number of people came out and resisted british crown forces, for want of a better word. and started firing at them. and sadly that resulted in the death of lyra mckee. where was the gunman? from footage i have seen, it appears he was around this area. are you surprised nobody has been charged with the murder of lyra mckee?

not really, no. why not? people have called for members of the community to inform but people in this community know the life of an informer. theyjudge by history and know exactly what happens to informers. if they give information? yes. saoradh blamed the police for lyra's death, claiming crown forces initiated the riot by raiding the house on the creggan. it was more than her friends could take. four days after her murder, they decided to act to show their anger and disgust in the most public way possible. it was kathleen's idea. that was the symbolism of the blood on their hands for what they had done. we all agreed. we would make sure it was done in a dignified fashion. nothing was done that would be adverse to lyra's memory. we went down and took red paint

with us and had our gloves with us. we parked and walked down to william street. it was eerily quiet. so eerily quiet. i definitely must have been nervous but the determination took over. irememberthinking to myself, nothing matters. they've murdered our friend. that was the emotion that day. i've never felt like that before. where the fear has gone. i was not afraid. i remember distinctly saying that, i am not afraid. let's go. they were stood with their arms crossed, staring at us. the saoradh members lined up around the building. staring at us. some were known senior dissidents. it was an incredibly brave gesture, openly confronting them may have put their lives at risk.

she is dead! nothing matters. take me to court. take me to jail. i don't care, i absolutely don't care. the rest of us are the same. we are strong women and we are not afraid. we are not afraid. did that intimidate you? i wasn't thinking about being afraid or intimidated. we can get a bigger message out, a more important message out, if we put hand prints. that is what they have. blood on their hands. saoradh‘s response was coldly dismissive. this what effect did the murder of lyra mckee have on saoradh and its support base? i think it was minimal. isn't that remarkable, given the universal horror? it is a republican community, saoradh were not involved in killing lyra mckee.

the ira took responsibility and apologised for killing lyra mckee. which i publicly asked them to do. an apology doesn't bring someone back from the dead. and it does not remove the trauma. experienced by her partner, experienced by anyone at the scene. there were people absolutely haunted by what happened to lyra and the cavalier attitude afterwards. i was getting stopped in the street and getting text messages congratulating me, saying well done. i think it was brilliant. it is definitely not in our name. not in my name. for you, lyra's nearest and dearest...

the world watched as father magill gave tribute to lyra at her funeral in belfast cathedral. the congregation included a roll call of political leaders from westminster, belfast and dublin. why in god's name does it take the death of a 29—year—old woman with her whole life in front of her... applause it was an unforgettable moment. the political leaders seemed embarrassed and didn't know what to do or where to turn. it was as if father martin's words had shamed them. for a fleeting moment, it seemed there was hope of a political breakthrough, but, alas, it was not to be. it was an incredibly courageous event. i acknowledged the bravery and the courage and creativity of those women in derry, friends of lyra's, when we can stand together and try and break some of this control. lyra's murder drew the world's attention to the new wave of violence festering in northern ireland's political vacuum.

a new ira bomber parks a car outside the courthouse in derry. he makes his escape. people pass by unaware. miraculously, no—one is killed or injured. it was the opening of the new ira's intensified campaign. a campaign that also continued to target police officers. the troubles aren't over for my family. and that's because i have a member of my family who is a catholic and a serving police officer. it's strange because after the good friday agreement, when we're supposed to be in a peaceful time, our house, my family home has been shot at. our family car has been burnt out. there has been sympathy

cards sent to my parents. sympathy cards? as in, with sympathy during times of death. peace is a very, very questionable thing at the moment because we know we have had lyra's murder in the last six months, but it seems to be every few days that there is a shooting or a beating, and that's not peace. it absolutely is not peace. last year, i watched these supporters of saoradh commemorate the easter rising of 1916. they recognise the new ira's determination to resist british rule. the new ira is believed to have a hardcore of around 100 gunmen, bombers and engineers, paid between £50 and £100 a week, backed up by up to 400 active supporters. brexit offers irish republicans the opportunity to realise our first—grade objective —

the end of british occupation. initially, they were on the back foot after lyra's tragic killing, but actually they gained confidence, borne out by the rising number of attacks in recent months. their sophistication is increasing. they have access to firearms and to explosives and to the sort of engineering that means they can make viable and dangerous devices. a priority of the police is to stop the organisation winning new recruits. in particular, from amongst the unemployed and alienated youth in deprived areas like the bogside and creggan, and similarareas in belfast and elsewhere. look, there are young people who are not doing particularly well at school, who do not have realjob prospects, who don't have great sense of what the future will hold. these for me are vulnerable young people to me and the likes of paramilitary organisations who will prey on these young people, who will groom these young people.

i would personally use the language of grooming in the sense of recognising and grooming and then bringing them into the ranks to continue the armed struggle. how do they do that? how do they recruit the next generation? well, it's similar to the isis model, if you like, where they exploit vulnerable young people. they will sell them drugs or get them into drugs and alcohol and they will influence them. they mobilise them onto the streets to bring them into the cause. dissident supporters of saoradh maintain that they and the new ira are the true heirs of militant republicanism. commemorating hunger strikers who have died down the years as martyrs for the cause. their sacrifice is designed to incentivise this new generation to carry on the fight. paddy gallagher left sinn fein. he then joined saoradh and became its spokesman in derry. he denies saoradh has any

connection to the new ira. "saoradh salute the men and women of violence." many people would take it to mean that saoradh salute the successes of these figures, which here, is the new ira. doesn't that imply that saoradh support the new ira? no, saoradh support the new ira? it is in reference to ongoing no, it is in reference to the ongoing struggle. most people would see it in contemporary terms as that. most people round here who support saoradh understand what saoradh is about. they acknowledge what they do within our communities. they know what media, british crown forces and pro—establishment parties put out in regards to the party is false. there's a fluidity that not every member of saoradh as we'd see it would be a member of the new ira and, similarly, not every member of the new ira may be a member of saoradh, but there is an overlap. i know some of these people. i grew up around some of these

people in the same area. the mural on the side of the wall saoradh has a rocket launcher. i don't think you can have a more simple message than that. they are one and the same. it is the political wing of the army. it's sinn fein in the area in the '80s. we've seen it all before. they cannot be any different because of the personalities. they are the same. derry‘s creggan estate is the stronghold of the new ira. here, it's a battle, as ever, for hearts and minds. the police need intelligence and the dissidents need both tacit and active support. when they kneecap drug dealers, dissidents say they are responding to community concerns over antisocial behaviour. the sentiment in the community in which they're based is one that they don't want them there and they are seen as people who ruin their lives, they exploit vulnerable young people.

they also have a softer and more subtle way of winning those hearts and minds. we've recently launched a food bank appeal. we've seen in the last couple of years the rise in the use of food banks, specifically here in derry. and where do these come from? it's local people that donate these items. isn't this the soft, friendly face of saoradh? well, you say soft, friendly face as though saoradh has another face. we're a socialist party. we work on behalf and for the working—class communities that we come from. if people need food banks, there's a food bank down there in springtown where you can get vouchers from your local representatives for it. you do not need to go to saoradh to get the food bank. we need more money for the welfare system and the health care system.

we definitely need serious crisis intervention services in terms of mental health and drug addiction support. but saoradh aren't providing those. as a community worker, kathleen has first—hand experience of where she believes the state is failing. i'm not surprised that saoradh and groups like saoradh exist. i'm sad that the reason why they exist is poverty. to me, saoradh and those groups are gap fillers. they fill the gaps that the state has left. dissident groups like the new ira also exercise community control through fear and intimidation. in the days after lyra's death, ominous graffiti appeared on the street where she was shot. it was a clear message to residents. they spoke to police at their peril. there's an undertone of threats and intimidation that you can understand. even if you were the person overlooking where that gunman

was standing and pulled that trigger, and you could identify them, you would be frightened about putting your name to a statement and giving evidence in court. the supreme challenge for police is to break the wall of silence. they say some of the community have provided information. but as yet, no—one has been charged with lyra's murder. do you know who killed lyra mckee? i think there's a groundswell of intelligence that would point us towards certain people. are you confident that the person who shot lyra mckee will be charged and prosecuted? i remain optimistic. six months on, the real derry girls continue to defy the dissidents. spraying a tribute to lyra on the free derry wall. it's now six months since lyra was murdered. no—one has yet been charged. does that surprise you? it doesn't surprise me. it does disappoint me. because lyra was the kind of woman

who would have said anything can happen. don't discount things. wait and see. so, i will continue to hope that something may happen. whether it's six months, a year, six years, ten years. i think it's important to stay focused on the hope. hope drives them on. hope, not only that her killer will finally be brought to justice, but that peace and the spoils of it that lyra referred to will finally prevail in derry and in northern ireland. hello, once again. i don't know about you, but i'm struggling to remember the last time i saw any meaningful sunshine and there's not a great deal of difference as we lose tuesday

and move into wednesday, with that low pressure very much the dominant feature, a number of attendant fronts. so, really quite wet conditions right from the word go across parts of eastern england, gradually migrating towards the borders. north of it, we've got this ribbon of cloud and rain stretching from the northern to the western isles, fringing into north of the great glen and, at the same time, some blustery showers just running along the channel coasts. still relatively mild, 9 to about 12 degrees or so. on into the evening commute, still a lot of rain to come across eastern scotland to the north—east of england. somewhat brighter skies in south—western scotland. maybe some western fringes of britain. even as far ahead as thursday, it is still that low pressure that's really driving our weather, but beginning to cede ground and that's allowing the first signs of a change in our weather type, certainly into the northern parts of britain but for the greater part of england and wales, you've still have the relatively mild air, enough cloud across northern and eastern parts of britain for there to be bits and pieces of rain. as the weather front comes south, heralding the change to brighter but colder conditions, initially on thursday

across the greater part of scotland, but eventually, as the low pressure finally moves off to scandinavia. so the high pressure comes in to dominate and it's the combination of the high to the west, the low to the east that generates quite a strong northerly wind and the clue there is the wind direction. it is a northerly, it's going to be a cold day but a much, much brighter day for the greater part of the british isles. but forget all about double—figure temperatures, bar the very far south—west. 3, 4, 5, 6 degrees for the north of britain, 7 or 8 in the south. and that's the way we start the weekend, a cold and frosty start to the day but yet another set of weather fronts wrapped around an area of low pressure just moving towards the south—western quarter. some really wet conditions there, but away from that south—western part of england, the southern part of wales, it's another cold and bright day. a lot of dry weather around as well, but again, maximum temperature somewhere between about 3 and 7 degrees. now, that weather system really dominates southern parts of britain

as we get on into sunday. the flow around its northern flank quite a noticeable easterly or north—easterly wind, a lot of cloud associated with those weather fronts. but elsewhere, until quite late in the day when we bring another little weather front to the north of scotland, again, it's a cold and frosty start followed by a bright, dry, sunny sort of day, but those temperatures again locked into single figures.
