Sadiq Khan: We can't play Russian roulette with fire safety

London's mayor has backed a decision to evacuate tower blocks, insisting "you can't play Russian roulette with people's safety".Sadiq Khan supported the move by Camden Council to move some 3,000 people out of their north London high-rise homes due to fire safety fears in the wake of the Grenfell Tower tragedy.The buildings are among 34 to have been deemed unsafe across the UK after emergency tests were carried out following the west London fire, which killed at least 79.
