The US firm that supplied cladding used on London’s Grenfell Tower says it has ended global sales of the product for use in high-rise blocks.

Arconic said it was discontinuing sales of Reynobond PE for tower blocks due to “issues” identified by the fire, which is feared to have killed at least 79.

The government said 75 buildings in 26 council areas had now failed fire safety tests – every one tested so far.

Theresa May said councils need to speed up tower block safety tests in England.

Communities and Local Government Secretary Sajid Javid said all hospitals and schools had also been asked to carry out “immediate checks”.
