Cladding on 259 high-rise buildings has failed fire safety tests, latest figures reveal.
The government announced plans to carry out tests on 600 buildings across the country after the Grenfell Tower fire in North Kensington, west London, on 14 June.

Details are continuing to emerge about how many high-rise buildings are affected and their locations.
One sample has passed the test but it is not known which building this relates to.
Barnet, north London
Cladding that was put up on three towers in Granville Road in 2012 is to be removed after failing the tests.

"While the difference in the cladding system at Granville Road mitigates the fire risk, we are not prepared to take any chances with the safety of residents."
