More than 250 firefighters were called to tackle the blaze, which London Fire commissioner Dany Cotton described as "truly awful and shocking" for the level of devastation it caused.
Police have confirmed that at least 30 people were killed in the fire, and the death toll might increase. We know that there are still bodies of those who died inside the building and we want to return those people to their families as soon as we possibly can. He said that the search and recovery operation in the 24-story Grenfell Tower continues, and it has been incredibly distressing for families.
Ronnie King, the UK's former chief fire officer, told Al Jazeera: "I wouldn't wish to denigrate those who installed the cladding because - whatever the cladding was - it did not have to be fire resistant under the building regulations", said King.
Trade Minister Greg Hands said Sunday the government is carrying out an "urgent inspection" of the roughly 2,500 similar tower blocks across Britain to assess their safety, while an opposition lawmaker urged the government to quickly secure documents in the Grenfell renovation for the criminal investigation.
Engineering experts and fire safety specialists believe the building's exterior cladding may have quickly fuelled the blaze, overwhelming fire protection devices.
Mr Cundy also said the death toll may still change, but not as significantly as it has in recent days.
"If, as we investigate, we identify issues that are a risk to public safety, we will not be waiting until the end of the investigation before we provide that information to the appropriate authorities".
"What I'm now absolutely focused on is ensuring that we get that support on the ground", May said in a BBC Newsnight interview.
There were also angry scenes outside the offices of the Royal Borough of Kensington and Chelsea, which was responsible for managing the 1970s social housing block, in a working-class enclave in one of London's richest areas.
Prime Minister May vowed on Friday to rehouse victims of the tragedy within three weeks, assuring that the cost of temporary accommodation will be met on their behalf.
Meanwhile, Prime Minister Theresa May on Sunday said that the response to the disaster had not been "not good enough" as she battled critics who targetted her post-election fragile government over the tragedy.
"I have friends in the tower and they are not telling us anything", said Salwa Buamani, 25, who came with her three-year-old niece on her shoulders.
