I heard years of Grenfell testimony. Here's why the disaster could have been prevented

Kate Lamble has been covering the Grenfell Tower disaster for six years .

For the past six years , a public inquiry has heard evidence about the disaster.

She examines what created the conditions for a disaster that was both foreseeable and preventable.

This is a story of corporate deceit, government deregulation drives and a construction industry in a race to the bottom.

Brian Martin advised ministers on the part of the building regulation guidance that covered fire safety.

He was given a series of warnings about the use of combustible materials on high-rise residential buildings.

After a cladding fire in Dubai in 2015 , Mr Martin was approached by industry figures who told him the combustible products involved in the blaze were being sold in the UK .

Mr Martin has acknowledged he did not escalate that warning to his bosses.

The lead architect on the Grenfell refurbishment, Bruce Sounes , told the inquiry he did not familiarise himself with building regulations on fire safety.

The lead counsel at the public inquiry called this a “merry-go-round of buck-passing’ In 2016 , the local council’s building control department signed off the refurbishment.
