Detectives investigating the Grenfell Tower inferno have interviewed the London Fire Brigade amid concern its stay-put advice to residents left their lives in danger.

Scotland Yard is examining whether the brigade, as a corporate body, breached health and safety laws in relation to both its own firefighters and the residents trapped inside.

Crews and 999 operators spent the first two hours of the disaster telling the block’s occupants to remain in their flats - before realising the blaze was wildly out of control.

It is feared the delay in ordering a full evacuation of the 24-storey building may have contributed to the death toll of the June 2017 tragedy, which claimed 72 lives.

Questions have also mounted about the adequacy of the training put in place by the brigade for tackling cladding fires in high-rise buildings after the Lakanal House fire killed six people in similar circumstances in 2009.

Dany Cotton, the commissioner of the London Fire Brigade (LFB) who faced fierce criticism over the emergency response, revealed an interview had been conducted with police under caution.
