tonight at a public meeting, angry survivors confronted the senior police officer investigating the fire, and the council leader, demanding answers. here's our special correspondent lucy manning. into grenfell tower and up the stairs. the narrow stairs. the only escape route. and it was covered with black smoke. bodies filled this stairwell. now those identifying victims climb up, struggling for breath. many of the residents who were told to stay during the fire didn't make it down these stairs. as the forensic work at grenfell tower continues, slowly, new details are emerging about what those inside were told on the night of the fire. the bbc has seen documents setting out how the residents of grenfell tower were told to stay in their flats until 2:47am. the first 999 call was made at 12:51am.

so for an hour and 53 minutes, those calling for help were told to stay put. it took nearly two hours for the advice to change to evacuate. these pictures from a0 minutes after the first emergency call show just how high the flames had reached. an hour later it had engulfed the whole tower. there's no doubt the firefighters were heroes, but the fire policy for tower blocks was and still is to stay put. the "stay put" advice is broadly sound. but clearly this was an unprecedented fire and at some point it was obvious the advice needed to change. whether it should have been changed earlier, i wouldn't want to speculate. for the families still waiting for relatives to be identified, the information that for nearly two hours the advice was to stay put is hard to digest. this man's mum, sister,

brother—in—law and their three children lived on the 22nd floor. kareem's uncle was on the top floor. does two hours sound like a long time? of course. like within 15 minutes the whole building caught fire. you know, after two hours, it's too late. when after that time, the chances have dropped for them and for everybody else. it's the most appalling... it's like as if... you know, you've taken away that chance. that chance. but when you say "stay in your house," you know, "stay in your house," you know, just... what can you say? firefighters did risk their own lives to try to save others. the bbc understands 31 were injured. almost all from smoke inhalation.

the london fire brigade said the "stay put" policy would be for the public and police inquiries to look at, but the advice can change as the fire changes. this is a flat where everyone did escape. but a month on debris is being sieved for remains. only 3a victims have been formally identified. i deeply understand the frustration families have and the answers they want. it is only natural. all i can say is be patient, we are doing our utmost best for you. but with trust in the authorities low, the new council leader's admission she has never been in a high rise tower block won't help. i accept i haven't been, i haven't been up a tower block, but i have been in a huge number of houses. tonight she and the senior investigating officer faced

a tense atmosphere. he was shouted down with cries of "arrest someone." the test of my investigation will be whether it is done properly. not quickly. can you arrest somebody? arrest the council, make arrests. please, do yourjob, make arrests first. you haven't been listening from the start and you're still not listening. a month on, and the families want funerals and justice. lucy manning, bbc news, west london. tonight hundreds of people attended a vigil near grenfell tower for the victims of the blaze. four weeks on, relations between the survivors and the authorities are still strained. our home editor mark easton reports on how the community has reacted in the aftermath of the fire. a black nail hammered in to london's conscience. grenfell tower demands your attention. in its shadow, the faces of the missing are everywhere.

on trees and walls and bus shelters, unblinking, it's hard to hold their accusatory gaze. more than 250 escaped the tower that fateful night, but around 80 people are missing or confirmed dead. floor by floor, the names and faces of all those we know didn't make it out. they arrived at grenfell from all over the world, more than 20 countries represented among the missing. families with small children who'd recently moved in, pensioners who lived in the block for over a0 years. and then, perhaps, there are others. the unknown. the fact that we still don't know exactly who and how many died in this fire a month later tells us something, i think, about society's relationship with the people who lived in grenfell. some were perhaps happy to be

anonymous, but others were simply marginalised, isolated and ignored. only the most vulnerable and desperate would have been eligible for a vacant flat in the tower. traditional council housing like grenfell has fallen out of fashion. fewer social homes were built last year than at any time since their invention. i mean, you look around, it's actually a beautiful estate. pilgrim tucker tried to give the residents of grenfell a voice through her work as a housing campaigner in the area. the fact that it's become so hard to get good social housing now and that more and more it's only the most vulnerable people who can qualify for the kind of housing that, really, everybody... should be available to everybody, means that there is a section here of people who were really disengaged, and i think that's a real shame and it shouldn't necessarily be like that. the fire has burned through the veneer of london life

to reveal the capital's invisible people. we are a tale of two cities. we have many invisible londoners, and i'm afraid there will be hidden victims. london mayor sadiq khan believes the fire has exposed the failure of politicians. their experience of politicians — of all parties, by the way — local politicians and national politicians, is them letting them down, is them making promises they don't keep. more of us have got to spend time there. more of us have got to walk in the shoes of some of those residents. the community has had to be resilient. this is the boxing club that used to meet in a gym at the bottom of grenfell tower, now destroyed. but a public fundraiser has meant the local boys and girls are back in training, in the corner of a nearby car park. it's harrowing, really that, you know, we might never know some of those victims, you know? nameless people. it's very, very, very sad and, you know, i wouldn't have expected something like that, actually,

to happen in the 21st century in london, to be honest. "in the heart of our great city, people live a fundamentally different life, don't feel the state works for them." the words of the prime minister week after the fire. along with a hope that its legacy is that we never forget the hidden people of grenfell. mark easton, bbc news, north kensington. the greatest witch hunt in political history, that's what donald trump has called the controversy surrounding his son after he released e—mails revealing that he met a russian lawyer last year who was said to have information from the kremlin which would help his father's election campaign. today the president said his son had been open and transparent and was innocent. our chief correspondent gavin hewitt is at the white house tonight, gavin. tonight, we have donald trumer... donald trump's son out defending himself after revelations from e—mails that last year he met a russian lawyer who he believed

would offer him incriminating information and hillary clinton. in retrospect, i probably would have done things a little differently. again, this is before the russia mania, this is before they were building it up in the press. for me, this was opposition research... in his interview, donald trumer said he hadn't referred the meeting to his father. it was such a nothing, there was nothing to tell. i mean, i wouldn't have even remembered it until you start scouring through this stuff. it was literally just a wasted 20 minutes, which was a shame. president trump was quick to praise his son's television performance, tweeting. .. so who are the key players involved in the meeting last year? the initial approach to donald trumer about a potential russian meeting came from rob goldstone, a british publicist. he helped schedule the appointment with natalia veselnitskaya, a russian lawyer.

also in the room was paul manafort, trump's campaign manager, and jared kushner, trump's son—in—law — a clear sign they thought the meeting would be significant. the e—mail shows an intent and a desire to have a foreign government interfere in the american election of the president. asking for that kind of assistance, if that was the assumption of the meeting. that in and of itself can be a crime. the white house has been active, pointing out that there has been no illegality, no law broken, no sensitive information exchanged. but that doesn't mean there are no risks in all of this for the trump administration. in this atmosphere of political crisis, focus turned towards capitol hill and the confirmation hearings for the new director of the fbi. he was asked whether he agreed with the president that the investigation by special councel mueller into russian meddling and lasted's election amounted to a witch—hunt. do you believe that, in light of the doanr e—mail and other allegations, that this whole thing about trump

campaigning in russia is a witch—hunt? is that a fair description of what we're all dealing with in america? senator, i can't speak to the basis of those comments. i can tell you that my experience with director mueller... i'm asking you is the future fbi director, did you consider this endeavour a witch—hunt? i do not consider director mueller to be on a witch—hunt. in an interview with the christian broadcasting network today, president trump tried to refocus attention back onto his latest legislative agenda and away from the questions about russia so preoccupying his administration. gavin hewitt, bbc news, washington. a state banquet has been held at buckingham palace tonight for the visiting king and queen of spain. this afternoon, king felipe addressed both houses of parliament. he said he was confident the uk and spain can reach an agreement over the future of gibraltar. our royal correspondent nicholas witchell reports. a state banquet at buckingham

palace, where hospitality is deployed in pursuit of diplomacy. tonight, one of the world's oldest monarchs, elizabeth of the united kingdom, accompanied one of its newest and tallest, felipe of spain, to dinner. a lavish occasion, but an opportunity for britain to cultivate another important european nation. the queen didn't mention the word brexit in her speech. but she did dwell on the power of the anglo—spanish connection. a relationship like ours, founded on such great strengths and common interests, will ensure that both our nations prosper, now and in the future, whatever challenges arise. the state visit had begun on horse guards parade, with a greeting between two monarchs who are distantly related — they‘ re both descendants of queen victoria. from horse guards to the carriage ride up the mall, one of the highlights for visitors, something donald trump is keen to do if he ever comes.

and in this relaxed atmosphere, business can be done and difficult issues touched upon. in the case of britain and spain, that means gibraltar. last year, king felipe called it a colonial anachronism. today, in a speech at westminster, he was more tactful. but he did call for a negotiated settlement. i am confident that, through the necessary dialogue and effort, our two governments will be able to work out towards arrangements that are acceptable to all involved. to that, the british government said the sovereignty of gibraltar was not up for discussion. a firm response, among the warm words of a state visit. nicholas witchell, bbc news, buckingham palace. that's a summary of the news. now on bbc news, it's time for newsnight.
