The Prime Minister said “it is imperative that there is full accountability” following the damning report.

He said: “This government will write to all companies found by the Inquiry to have been part of these horrific failings as the first step to stopping them being awarded government contracts.”

Starmer promised a full government response to the report within six months but added “there are some things I can say right now.”

He said: “There are still buildings today with unsafe cladding. And the speed at which this is being addressed is far, far too slow.

“We will take the necessary steps to speed this up.

“We will also reform the construction products industry that made this fatal cladding so homes are made of safe materials.”
