JUST ONE in 50 socially owned tower blocks are fully fitted with sprinklers, an investigation published yesterday has revealed.

And seven in 10 blocks have only one staircase for evacuation, according to the shock results of a BBC Breakfast probe covering half of Britain’s council and housing association-owned towers.

After the disaster at Grenfell Tower, which did not have sprinklers, ministers said they might retrofit sprinklers to blocks depending on the findings of the public inquiry into the fire.
