The Grenfell Tower fire would have had little opportunity to spread from the flat it started in if the exterior of the tower had not been renovated with combustible material, a leaked report has said.
According to the report, seen by the Evening Standard, the 2014-2016 refurbishment of the building failed to meet fire safety standards and deficiencies in the new facade helped the fire to spread up the building's exterior.
The fire, which started in a fridge-freezer in a fourth floor flat, travelled through a nearby open window before spreading via the external cladding, according to the newspaper.
The fire damage was so severe that, had the building been build to the less stringent requirements of current building regulations, "it is likely the tower would have collapsed", the report allegedly said.
Some 71 people died in the west London tower block fire on June 14 last year.
The report, by fire investigation experts BRE Global, was quoted in the Evening Standard as saying:
Dated January 31, the report was prepared as part of the police investigation into the June 14 fire.
It also identified flaws with the cavity barriers, window frames, "door closers" and flammable insulation and cladding.
