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.
The Prime Minister set out the scope of the probe following recommendations from Sir Martin Moore-Bick, the retired Court of Appeal judge leading it.
It will examine the actions of authorities before the blaze, including Kensington and Chelsea Council, and how the aftermath was handled, but stops short of scrutinising broader social concerns.
Prime Minister Theresa 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 Tuesday's 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.
Sir Martin 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.
The Prime Minister 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 on June 14 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."
Sir Martin himself came in for criticism from some campaigners following his appointment amid suggestions he was not suitable for the role.
Their concerns centred on a 2014 case in which Sir Martin sided with Westminster City Council's decision that mother-of-five Titina Nzolameso should be rehoused 50 miles (80km) away.
His ruling was later overturned in the Supreme Court, but, with the majority of those who escaped the tower waiting to be rehoused, Sir Martin's decision-making prompted alarm.
Justice4Grenfell, one of the campaign groups working with survivors, said it was pleased that Sir Martin 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."
Mayor of London Sadiq Khan called on Sir Martin to "do everything in his power to deliver the inquiry's interim report as quickly as possible".
He said: "Residents urgently need answers, and more lives are potentially at risk if we do not act quickly to establish the facts.
"We need to ensure such a tragedy can never happen again.
"There are some key concerns not covered by these terms of reference.
"It is vital that the wider questions around social housing are answered if the community's shattered confidence is to be restored, alongside an investigation into our ability to respond to emergencies and the fire risk from household appliances.
"If these are not to be addressed in the public inquiry, the Government must set out urgently how it will make sure these critical issues are fully addressed in a parallel process."
The Lancaster West Residents Association called the inquiry's scope a "missed opportunity".
They said: "The Prime Minister first said that 'no stone would be left unturned'. The terms of reference fail to achieve this.
"We strongly believe that the public inquiry should investigate not just the cause and spread of the fire but also the underlying cultural attitudes and ethos prior to the fire towards tenants from both KCTMO (Kensington and Chelsea Tenant Management Organisation) and RBKC (Kensington and Chelsea council)."
Chair of the association, Olesea Matcovschi said: "This disaster did not happen in a vacuum but has its roots in longer term failure and indifference to social housing by the KCTMO and RBKC.
She added: "Wider consideration of culture and social housing cannot be left to separate politicians and needs independent scrutiny."
The Radical Housing Network, of which Grenfell Action Group is a part, said: "Prime Minister May pays lip service to 'broad questions on social housing policy' and yet these very questions are excluded from the inquiry terms.
"Investigators should be looking at the social policies which allowed such a tragedy in 21st Britain, and the way these have created a housing system in which some people matter more than others."
