London mayor Sadiq Khan has called for commissioners to take over the running of Kensington and Chelsea Council after its leader and deputy leader tendered their resignations in the wake of the Grenfell Tower disaster.
Nicholas Paget-Brown said he had to share responsibility for "perceived failings" by the authority in the aftermath of the tragedy which claimed at least 80 lives.
His deputy, Rock Feilding-Mellen, also intends to stand down from the council, which also lost its chief executive Nicholas Holgate, following a barrage of criticism over the authority's response to the fire.
Mr Khan, who welcomed the resignation, said the government had "no option" but to appoint "untainted" commissioners who had "a genuine empathy for local people and the situation they face" to take over running the authority.
He said: "The council now needs to find a way to move forward and find a way to restore the confidence in that community.
"That can only be done with new leadership and a new approach that reaches out to residents who quite rightly feel desperately neglected.
"I ... feel the response from the council and subsequent breakdown in trust is so severe that there is now no alternative and the Government needs to step in quickly."
Commissioners were brought in to run Tower Hamlets Council in 2014, following a critical independent report into the council's award of grants and sale of properties under former mayor Lutfur Rahman.
It comes as Jeremy Corbyn said he has written to Prime Minister Theresa May urging her to increase the scope of the public inquiry.
He has asked for a two-part inquiry, the first looking at specific issues around the fire in at the 24-storey building in Kensington, west London, and reporting back soon, with an additional second part "looking at the national issues".
However Yvette Williams, one of the organisers of the Justice 4 Grenfell campaign group, said the community would not accept commissioners imposed on them without consultation.
She said Grenfell survivors and victims' families are "very, very angry" and claimed that one former resident called her yesterday to reveal their rent for the tower block had been deducted from their bank account.
Ms Williams also criticised the government for not demanding Mr Paget-Brown's resignation.
She told BBC Radio 4's Today programme: "I do support the mayor in terms of a commissioner-led borough, but how are those people going to be selected?
"That's the process we don't know."
