Theresa May vows major inquiry into use of flammable cladding after Grenfell Tower blaze

Prime Minister Theresa May has said there must be a "major national investigation" into the use of potentially flammable cladding on high-rise towers across the country over a period of decades.

Mrs May's call came as Cabinet was informed 95 samples of cladding from tower blocks in 32 English local authority areas have failed fire safety tests - amounting to 100% of all samples submitted by councils in the wake of the Grenfell Tower tragedy.
