we felt like. new fresh questions raised about the suitability of the installation move the accused. the youngest victim of the manchester arena bombing which happened a year ago tomorrow, we hear from happened a year ago tomorrow, we hearfrom her happened a year ago tomorrow, we hear from her father. i want to put ona hear from her father. i want to put on a concert for the world to stop and listen. the duke and duchess of sussex and they are delighted with the official portraits of their wedding day. and beautiful blooms abound at chelsea as we get a preview of their flower show. and coming up on sports day, it is a massive week for liverpool ahead of

their champions league final on saturday. good evening. relatives of those killed in the grenfell fire have been remembering their loved ones. the first victim to be commemorated was logan gomes who was stillborn in hospital shortly after his pregnant mother escaped from the braves err blaze. 72 people died after flames engulfed... so many killed, so many lives cut short. none more so than logan gomes. not even born when he died. after grenfell. his family

shared pictures with the inquiry. he looks like he was just sleeping. as babies do. at that moment, we felt like our hearts had broken. but at least we were able to hold him and to be with him. the joy of the baby shower, decorating the nursery, choosing a name, all destroyed. you

don't know what you're made of until you are broken. mohamed neda, fled the taliban in afghanistan. his final message for his family played to a silent inquiry run. his wife's tribute read out by her solicitor. his hopes and our genes have been

shattered. he was my husband, he was my best friend. i miss him, so much. he will always be the love of my life. had lived in grenfell tower for more than 20 years, he had three big clu bs, than 20 years, he had three big clubs, family, friends, and chelsea, not always in that order, his sister said. he was the linchpin of our family, and touched the lives of so many people. 0nce family, and touched the lives of so many people. once you had met denis you would never forget his warmth, wit, cheeky smile and love of life. there is a gaping hole in our hearts that can never be filled and it hurts, it really hurts. a short but poignant tribute to 69—year—old joseph daniels, made by his son. the

events of that night took his life and all trace of existence in this world, he never stood a chance of getting out. it should never have happened. mother and daughter, mary mendy, and khadija saye died together, mary was remembered as strong and ha rd—working. together, mary was remembered as strong and hard—working. the dj, a photographer, lauded for her talent, afamily photographer, lauded for her talent, a family solicitor read the tribute —— khadija saye. a family solicitor read the tribute -- khadija saye. for every birthday, christmas and new year ‘s, two empty chair's, christmas and new year ‘s, two empty chair ‘s, but they will forever own a position in our hearts. then the enquiry heard khadija saye's own words about the future she would never have. one of my friends said, you are an artist, and i said, i am, now! it'll be quite an emotional moment to actually say, khadija, you have done it! the tower is now largely covered up, the grenfell

families are desperate for the truth to be exposed. well, as the inquiry begins to look at the causes of the fire, attention will turn to the recent refurbishment of grenfell tower and in particular the addition of exterior cladding and insulation. an investigation for tonight's panorama programme has found that the firm which supplied the insulation, celotex, may have misled the contractors doing the refurbishment about its suitability for use in high rise buildings. richard bilton reports. move back! way back! it started as a kitchen fire. look at this madness that's going on. oh my god. but grenfell burned out of control because the building was wrapped in flammable material. these are the two products that covered grenfell that night, cladding with insulation behind. look at what happens when there's a flame, the cladding core melts and lights the installation.

before the disaster, these two were never tested together. the manufacturers knew they were being combined on grenfell but didn't warn anyone on the project. fire spread up grenfell in 15 minutes from the second floor to the 22nd floor. and that is very, very fast fire spread. because you had so much combustible material, that would be equivalent to having four large petrol tankers full of petrol, all burning at the same time on grenfell tower. this is the type of installation that was on grenfell. —— this is the type of insulation that was on grenfell. it burns this quickly and that smoke is poisonous. the manufacturer, celotex, knowingly misled buyers about this product. they said it was suitable for use on the refurbishment of buildings above 18 metres. it wasn't.

they were warned their marketing was misleading but they didn't stop. that is remarkable and staggering and i think people will be extremely angry about that. it is unbelievable that people can operate like that. it gets worse. we have discovered the insulation on grenfell had never been tested for tower blocks. panorama understands the product that passed the safety test contained extra fire retardant. we think a more flammable version was then sold for public use. well, words fail me. this is absolutely mind blowing. this material is all over the place. the insulation that burned out of control on grenfell

should never have been there. but celotex targeted the grenfell refurb and specifically offered their untested insulation. we have been advised that the company's behaviour could amount to corporate manslaughter. celotex say they can't comment because they are cooperating with the police investigation and the public enquiry. but they haven't denied panorama's allegations. richard bilton, bbc news. lucy manning joins me now. how would you sum up the first day? there is a time for everything, there will be a time for evidence and experts and difficult questions and experts and difficult questions and difficult answers, but today was

and difficult answers, but today was a day, a time for the bereaved, a time for them to remember and cry and there was certainly lots of tea rs, and there was certainly lots of tears, everyone in the enquiry room was weeping as they heard the details of the lives of the young and the old and those who were not yet born who died at the fire in g re nfell yet born who died at the fire in grenfell. the enquiry chairman told those who spoke today that he was finding it emotional to listen to them but appreciated giant to hear more about the lives of those who had died. the families will give their tributes for the rest of this week and into next week and then, the first phase of the enquiry will hear from those experts, there will be evidence from the firefighters who were there that night and evidence from the survivors. the enquiry trying to find out how and why the flames burned so quickly and what decisions were taken that night. 72 seconds of silence at the start of the enquiry, 72 reasons we re start of the enquiry, 72 reasons were heard and are being heard as to

why it is so important this enquiry finds out just what why it is so important this enquiry finds outjust what happened that night. and you can see the panorama programme, "grenfell: who is to blame?", at 8 o'clock this evening on bbc1. the former labour mayor of london ken livingstone says he's leaving the party. he had been suspended after allegations of anti—semitism following comments that adolf hitler had at one time supported zionism. this afternoon he spoke to bbc london. well, i've decided that rather than this drag on for another two years, it's better for the labour party if ijust resign. i can go back to campaigning on issues like the environment, supporting jeremy's economic plans, and all of that. but if i was to stay in and fight this, my lawyers say, it could take two years more. our political editor laura kuenssberg is at westminster for us. laura what's prompted this? jeremy corbyn and ken livingstone are old friends, ken livingstone was

one of the people who came back in from the cold whenjeremy corbyn took over the labour party, having been frozen out for quite some time. but he got himself into trouble over comments he made suggesting adolf hitler was at one time a supporter of zionism, comments he made on many occasions, making what he believed we re occasions, making what he believed were historical arguments. but he was caught up in an investigation by the labour party, and withjeremy corbyn himself saying that labour had not done enough to stamp out anti—semitism, that prejudice againstjewish people, ken livingstone, for many people, staying in the labour party was a block for the party being able to move on block for the party being able to move on and crack down with the problem and deal with it as so many mps have called for. some labour mps will frankly be absolutely delighted to see the back of him, knew is due to see the back of him, knew is due to have his case raised very shortly by the party's governing body. he has said that he was not pushed out,

he has jumped rather than has said that he was not pushed out, he hasjumped rather than wait has said that he was not pushed out, he has jumped rather than wait for the process to continue but i understand conversations between the two old friends may well in the end have hastened the departure of mr livingston. the duke and duchess of sussex have released official portraits from their wedding. in a message released with the photographs, the couple said they felt "lucky" to share their day with their guests, and also with those watching around the world. the pictures were taken by photographer alexi lubomirski, as nicholas witchell reports. there were certainly no shortage of photographs being taken on saturday, as the carriage procession made its way through windsor and up the long walk, it seemed as though everyone was holding up a mobile phone to take a snap. but it was after harry and meghan had reached the end of the procession and made their way into the comparative calm of windsor castle that the official wedding pictures were taken is a group shot of the couple,

their close family, and the bridesmaids and page boys. standing to the couple's left is meghan's mother, doria ragland, who made such a deep impression at the wedding with her poise and dignity. the queen and the duke of edinburgh are seated in front of prince charles and the duchess of cornwall. among the bridesmaids and page boys, prince george is smiling broadly, princess charlotte is sitting on her mother's lap. the second picture shows harry and meghan in a more relaxed pose with their young attendants. george has an even bigger smile. the third photo is a black—and—white portrait of the bride and groom relaxing and looking very happy on the east terrace of windsor castle. so, what do people make of the pictures? to see a woman of colour in the royal family which inherently has been white,

that acceptance does mean it's a step forward. the commonwealth history, our history and a bit of history in the making. it's nice to see philip there as well. for the queen, visiting the chelsea flower show this evening, the wedding and the positive reaction to its images of diversity will surely be a matter of relief. she knows the family's younger generation is stepping forward now and it seems well—equipped for the future. nicholas witchel, bbc news. our top story this evening: moving tributes are paid to some of the 72 victims of the grenfell fire on the first day of the inquiry into the disaster. we are at the chelsea flower show where after preparations for months, finally designers and gardeners show off their work. coming up on sports

day in the next 15 minutes it is a coup for harlequins but it could be bad news for england as paul gustard ta kes bad news for england as paul gustard takes on the top job at the stoop. tomorrow marks one year since 22 people were killed by a suicide bomber at an ariana grande concert at manchester arena. eight—year—old saffie roussos was the youngest victim of the attack. as the anniversary of her death approaches, her father has told the bbc that he wants her life to be remembered with a special concert. judith moritz has been hearing from andrew roussos, as well as from others affected by the tragedy, about how they are coping one year on. losing your eight—year—old child is, it's changed life for ever. it'll never be ok again. at night i couldn't sleep, like crowds, loud noises, ijust hated. this experience has brought us all together.

it's the psychological part that's been the hardest, i think. devastation caused in seconds has changed lives for ever. children traumatised, survivors recovering, families broken. like that of little saffie roussos, the youngest child to die. her parents are still reeling. how has this year been? dreadful. you know, having a child that young and losing her in such a way, we'll never be ok. this concert‘s not for us.

i want it to be there to support victims of future attacks. we are all really shocked at the lack of support from our government. so there's no government support? nothing. you're turning to charity? yes. when it happened, it wasjust a really scary experience. ii—year—old ava wasn't directly caught in the blast, but still struggled emotionally afterwards. she's one of hundreds of traumatised children to be supported by the warrington peace centre. we have been talking about different coping techniques. it's like always good experiences coming here. it's helped a lot? yeah. ava and her mum have also found solace in music. the manchester survivor's choir is giving them strength. everyone singing here survived the bomb.

singing together with other people who understand what you're going through, is a positive message instead of seeing the negative in the world. it's not just about the choir. the people here know how it felt so that makes a big difference. the choir have agreed to perform in the city centre for tomorrow's anniversary, although they know that'll be difficult. that is a common theme, we are struggling going into crowds and busy places. with each other, hopefully we'll all do it and that she's already serving a five year

sentence for plotting to topple the iranian regime, a charge she denies. the 39—year—old was detained in april 2016 while travelling home with her daughter. there's been further disruption to rail services across england. a big overhaul of train timetables has led to delays and cancellations for a second day. danny savage is at manchester piccadilly for us this evening. what's the picture where you are? this area was one of the worst affected in the uk today. the main provider of commuter services in this part of the country is northern rail. 90% of the services have been affected by the new timetable. they say 1300 services have been added per week, but a rush hour this morning they were quickly dubbed northern fail. passengers were

turning up for service is scheduled to run on the new timetable to find them cancelled. from bolton, people trying to get into manchester said the scheduled rush—hour services failed to turn up and the few that did were severely overcrowded. stu d e nts did were severely overcrowded. students going for their gcse exams we re students going for their gcse exams were missing services and going late and having to be taken by car to make sure they did get there in time. northern rail said it was down toa time. northern rail said it was down to a shortage of drivers be combined with the new timetable to cause serious problems with andy burnham, the mayor of greater manchester calling the situation appalling and calling the situation appalling and calling for the transport secretary to intervene. also problems in the south—east where most of the commuters are in the uk. go via thames link put hh.’ ' commuters are in the uk. go via thames link put g trains ifiifi§§ilfik gut fifi. ii!!! essa £5323 the igimee’uge gut efi. 321g eete3 $32.3 the but there igimee’uge gut efi. 321g eet.e3 $32.3 did 1e but ibea . the ram? the m was it wasn't was expected e the .. —~ was expected ; the south—east. you. a leading scientist believes he has

found the cause of the most common cancer in children. he says that coming into contact with too few microbes early in life can leave a child vulnerable to a type of leukaemia. 0ur health correspondent james gallagher has more. hugo has a cancerous immune system. he was diagnosed with acute lymphoblastic leukaemia when he was two and the disease means he has difficulty walking. he's now in his third year of chemotherapy. it's all he's ever known, but yes, certainly the early part of his treatment was really gruelling. all the side effects you'd expect, vomiting, hair loss, tiredness, lack of appetite. hugo's type of leukaemia is more common in affluent societies, but the reason why has been hotly debated. now scientists think they have the answer. it starts with a genetic mutation in the womb and then in the first year of life, a lack of exposure to microbes fails to train the immune system correctly. so if there is an infection

in childhood, the immune system malfunctions and it can lead to leukaemia. part of the problem is how sterile and germfree our lives have become. but the researchers say using bacteria may prevent the disease. if all of our conclusions are correct, it should be preventable by exposing young infants to benign bacteria which primes the immune system adequately. coming into contact with beneficial bacteria is complicated, playing with other children, having older siblings, going to nursery and being breast—fed all play a major role. it's notjust about embracing dirt. i think you have to let the toy which drops on the ground go and just sort of say, well, that's that and not get too caught up on it. ijust believe sometimes it's good to have some germs around, probably it's better for the immune system. this study adds to growing recognition that bacteria are vital for our health and well—being. failing to train the immune system has been linked to diseases

like type one diabetes, to allergies and now leukaemia. but this is absolutely not about blaming parents. it's an acknowledgement that the progress we are making as a society and in medicine comes at a price. james gallagher, bbc news. it's the highlight of the horticultural calendar, showcasing some of the most creative garden designs from around the world. ahead of the chelsea flower show‘s public opening, we were given a sneak preview. the theme for this year's event is health and well—being, exploring how plants and green spaces can improve lives. helena lee is there for us this evening. helena. this is one of the more beautiful gardens here on the main avenue at chelsea. one of many that are being showcased here throughout the week. this, the world's most prestigious flower show, after months of preparation, garden designers finally get to showcase their work. and everything's in full bloom.

one of the main showpieces aims to promote the benefits that green spaces have on mental health. this garden aims to highlight the importance of gardening to families who have been displaced by war. and this, another exhibit, designed to make an impact. highlighting the issue of plastic waste ending up in our oceans. these really tell the story. that's the stomach contents from from one albatross chick, and the parents go to the ocean to pick up food, and it should be something like squid or cuttlefish, but instead they are picking up plastic. today, some well—known faces share their love of gardening. i sit in it, that is what i do and i enjoy it. i am trying to think of the names of some of the flowers that i have, i tried to learn them before they came out, allium... probably a peony. and i love old—fashioned geraniums. dark red geraniums, all because i was brought up in suffolk, and it's

a very suffolk thing. some final finishing touches before the show opens to the public tomorrow. tens of thousands of people are expected to enjoy the very best of what the gardening world has to offer. time for a look at the weather. here's ben rich. spring sunshine was part of the story today, but not the whole story. in places, storm clouds have been gathering. you can see the way beast blunder storms kicked off across part of the south—east, some into the midlands and parts of north—west england as well. they have brought a lot of rain and frequent lightning. they will fade away this evening. for most it will bea dry away this evening. for most it will be a dry night with clear spells. more cloud for northern ireland and north—west scotland but much of the

rain from today will tend to fizzle. temperatures overnight around eight to 11 degrees. tomorrow, high pressure in charge of the scene. a lot of fine weather again but this frontal system will hang around across scotland and northern ireland. while it won't be as wet as it was today across scotland and northern ireland there will be large areas of cloud. could be misty and murky close to the north sea coasts as well with an easterly breeze making it feel cool. away from these areas, good spells of spring sunshine and again, the risk of thunderstorms in the south. i wouldn't want to completely rule out a shower at the chelsea flower show but it should be mostly dry. but the thunderstorm cannot be ruled out. on wednesday, a lot of the same in many places. should be bright across scotla nd places. should be bright across scotland and northern ireland but a chance of a thunderstorm in the south. where we will have most of the heat. 23 degrees but even

further north in edinburgh, a high of 20. a quick look at things towards the end of the week, some spring sunshine but the potential for showers in the south. but mainly it's not too bad. that's it. now on bbc one we can join the bbc‘s news teams where you are. this is bbc news — our latest headlines: the public inquiry into the grenfell tower fire has opened with tributes to the 72 people who died — the inquiry chair called it the worst tragedy to hit london since world war two. ken livingstone is to resign from the labour party — the former london mayor is currently suspended over allegations of anti—semitism, which he denies. rail timetable changes have caused problems for some commuters — disruption and cancellations have hit many routes in england. nazanin zaghari—ratcliffe — the british womanjailed in iran —

has been warned to expect to be convicted of a fresh charge of spreading propaganda in the country. in a moment it will be time for sportsday, but first a look at what else is coming up this evening on bbc news.
