The Grenfell Tower public inquiry has come under attack from politicians for failing to include the issue of social housing in its terms of reference.
British Prime Minister Theresa May set out the scope of the probe following recommendations from Sir Martin Moore-Bick, the retired Court of Appeal judge leading it.
At least 80 people are dead, or missing and presumed dead, from the inferno that destroyed the 24-storey tower block in west London on 14 June as families and children slept, and that figure is expected to rise.
The inquiry will examine the actions of authorities before the blaze last June, including Kensington and Chelsea Council, and how the aftermath was handled, but stops short of scrutinising broader social concerns.
Mrs May said the problem would not be "unanswered", instead allocating Housing Minister Alok Sharma to review social housing.
Emma Dent Coad, the Labour MP who represents the west London neighbourhood, said the development was "precisely what we feared".
She said: "We were told 'no stone would be unturned' but instead are being presented with a technical assessment which will not get to the heart of the problem: what effects, if any, the lack of investment into social housing had on the refurbishment project.
"The Government has delegated this responsibility to an in-house team. We have no confidence whatever in the ability of Alok Sharma and a few politically compromised individuals to take on the task of answering this most important question."
The MP also criticised the apparent speed of the announcement, coming less than two weeks since the public consultation closed, having received more than 550 submissions.
She continued: "How can the community possibly have faith in an inquiry with terms of reference so hastily determined by the Prime Minister and her Government?
"It is a complete betrayal of everything we were promised. Clearly, the Government are running scared."
Shadow housing secretary John Healey said on Twitter: "Deeply unsatisfactory for PM to set Grenfell Inquiry terms of ref to exclude housing policy failings - closing off criticism of govt policy."
With the terms of reference announced, the inquiry has officially begun and will hold its first hearing on September 14, with an initial report by Easter.
Judge Moore-Bick will also scrutinise the "adequacy" of building regulations, the recent refurbishment of the block and the causes of the fire, the Government said.
He suggested in a letter recommending the scope of the inquiry that social housing policy should not be included.
Mrs May accepted in full the recommendations, but said: "I am determined that the broader questions raised by this fire - including around social housing - are not left unanswered.
"We are taking action, with the Housing Minister meeting social housing tenants to discuss the challenges they face and we will be setting out further proposals in due course."
Survivors and campaigners had pressed for systemic issues underlying the cause of the tragedy to be scrutinised.
Addressing these concerns, the Government said Mr Sharma will meet as many social tenants as possible, both in the west London neighbourhood and across the country, to build up a picture of the issues confronting them and work out a national approach.
Joe Delaney, who has worked with the Grenfell Action Group and was evacuated from an adjoining block after the fire, said the scope seemed "decent enough".
He told the Press Association: "The terms of reference seem wide enough to be able to cover the immediate causes of the Grenfell Tower disaster but won't cover wider issues regarding social housing.
"Whilst I think such a debate should be had, I don't think Moore-Bick's inquiry is the forum.
"However, it is vital that Moore-Bick's inquiry covers relevant issues in detail and with a thoroughness that will ensure that all those responsible are identified."
Judge Moore-Bick himself came in for criticism from some campaigners following his appointment amid suggestions he was not suitable for the role.
Justice4Grenfell, one of the campaign groups working with survivors, said it was pleased that Judge Moore-Bick had taken on board residents' concerns, but voiced concern at the absence of wider issues.
Despite previous indications that the group could withhold support from the inquiry, spokeswoman Yvette Williams said it could consider working with Sir Martin if he appointed community advisers.
She said: "When Moore-Bick first came down he said he was only going to go for something narrow and so it is good that he has listened to the community voice in terms of broadening those terms of reference.
"If he makes an announcement ASAP that he will have a team of community advisers on that panel, then we will start to develop some more trust in the process.
"He is not looking at the broader social issues for one, which we think is majorly central to this situation, and if he goes on with no community advisory rep, we would have a lot to say about that."
Elizabeth Campbell, the leader of Kensington and Chelsea Council, said: "We are fully co-operating with the inquiry and we will make any person or document available to the authorities, as required.
"I echo the wishes of the local community - we must find out what went wrong and make sure it never happens again, not only in this borough, but anywhere in the UK."
