London's Metropolitan Police say there are grounds for corporate manslaughter charges over the Grenfell Tower fire disaster.
They say the decisions been made after gathering a "huge amount of material" and talking to witnesses.
Representatives from Kensington and Chelsea Council and Kensington and Chelsea Tenant Management Organisation will now be interviewed.
Police sent a letter to residents affected by the disaster.
The force added that the facts were "simply an update on the investigation so far", adding: "The content of this note should not be taken to conclude that the identified offences and organisations are the only offences, organisations or individuals that are being investigated."
Yvette Williams, a coordinator at the Justice 4 Grenfell campaign group, said the move would help restore trust between the police and the community.
At least 80 people were killed when the blaze ripped through the 24-storey block of flats in London on June 14th.
