London - The leader of the local council which owns Grenfell Tower in west London, where at least 80 people died in a huge fire, and the head of the housing trust managing the building stepped down on Friday as the political fallout from the disaster continued to widen.

Conservative Nick Paget-Brown, the leader of the Royal Borough of Kensington and Chelsea council, resigned after criticism of his response to the fire, most recently by the government earlier Friday, the BBC and other media reported.

The Kensington and Chelsea Tenants' Management Organization, which managed the social housing block for the council, said its management board had agreed that Robert Black "should step aside from his role as chief executive of KCTMO in order that he can concentrate on assisting with the investigation and inquiry."
