Number of high-rise buildings found to have hazardous cladding rises to 60

Some 60 high-rise buildings in 25 local authorities across the country have now failed fire cladding safety tests after the Grenfell Tower disaster, the Government has said.

Around 600 buildings across the country are believed to have similar fire risks, of which at least 20 have been confirmed to have the risky and unauthorised cladding.

"I'm going myself back to the blocks to knock on doors and have those conversations", she told BBC News.

Separately, cladding is to be removed from nine tower blocks in Salford while two buildings in the town of Bootle also had cladding that failed tests.

As for the Grenfell Tower investigation, police said they are considering manslaughter charges among the criminal offenses that may have been committed at the high-rise building. "You can't play Russian roulette with people's safety", he told Sky News.

Refurbishment of the building, including cladding, was overseen by Rydon, the company involved in the refit of Grenfell Tower.

On Friday, authorities ordered the evacuation of four tower blocks in the Chalcots Estate in north London out of safety concerns - a move backed by Sadiq Khan.

After evacuating all five blocks, the council announced that one of the five - a smaller tower called Blashord - didn't need to be evacuated, and told residents they could return.

"I've made the really, really hard decision to move the people living there into temporary accommodation while we do the urgent works to guarantee safety", Gould told reporters outside the public housing complex. The majority of the residents of the four buildings were evacuated on Friday night.

Residents challenged Georgia Gould, leader of the council, yesterday over plans for evacuation, and about 200 people were refusing to leave the tower blocks until they were told that they would have somewhere to go. Fourteen apartment blocks have so far tested positive for combustible materials.

The DCLG said Doncaster, Norwich, Stockton-on-Tees and Sunderland all had buildings that failed tests, while Manchester, Plymouth and Portsmouth have already been named.

Gould, the Camden council's leader, said it would take up to four weeks to fix the blocks that were evacuated.

Stephen Ledbetter, former director of the Centre for Window and Cladding Technology, said it would cost around £1.2m to re-clad a tower block the size of Grenfell.

"We will speak to local authorities, landlords, tenants and of course the Scottish government as part of this inquiry".

Camden Council said the blocks were being door-knocked one at a time for safety reasons, starting at Taplow then working through Burnham, Bray, Blashford and Dorney.

"I would also urge everyone to fit smoke alarms in their homes and test them regularly", he added.

Others said they had been out with friends when they heard from the media that their homes had been evacuated.

As tests continue to avoid a repeat of the horror which broke out at the Grenfell Tower on June 14, the Association of British Insurers said it had warned of the risks posed by cladding in feedback to a government policy document.
