London mayor Sadiq Khan wants PM's answers today over fire failures

London's mayor Sadiq Khan has written to Theresa May demanding immediate answers over failures at Grenfell Tower.

In a lengthy letter to the Prime Minister, Mr Khan criticised the support and information being given to residents, as well as the relief efforts for those left homeless by the horror fire.

He also called for an update on measures to ensure a similar tragedy does not strike any other high-rise tower blocks and the immediate implementation of previously proposed safety rules.

Mr Khan urged Mrs May to chase prosecutions should anyone be found to have been "negligent" over the disaster, as he called for residents of the north Kensington building to be given free legal representation.

Mr Khan told the Prime Minister he expects answers later on Friday.

The mayor, who visited the scene of the tragedy on Thursday, described local residents as "distraught, frustrated and increasingly angry".

He wrote: "They feel the Government and local council haven't done enough to help them in the aftermath of this horrific incident, or to provide answers to their increasingly urgent questions."

Mr Khan said residents "cannot comprehend" why they are not being given more information about missing family members and friends.

Attacking the "insufficient support" for victims of the fire, the mayor said "scale of this tragedy is clearly proving too much" for Kensington and Chelsea Council to cope with.

He noted some Grenfell Tower residents were still sleeping in the nearby Westway Sports Centre on Thursday night despite claims accommodation had been found for all of those who lost their homes.

With questions over the tragedy focusing on the installation of exterior cladding on Grenfell Tower during a recent £8.6m refurbishment, Mr Khan said residents in other renovated tower blocks were "terrified" the same thing could happen to them.

If the Government believes any other tower blocks could be at risk, the mayor demanded residents be rehoused immediately.

He added: "Please also confirm that there will be an immediate implementation of the improved safety rules proposed in 2013 but still not implemented."

Mr Khan repeated his call for the public inquiry into the disaster, announced by the Prime Minister on Thursday, to provide an interim report this summer "at the latest".

He said: "We cannot afford to wait years for the outcome".

The mayor said residents should not be saddled with legal costs for participating in the inquiry.

Mr Khan vowed to "continue to fight alongside this community to ensure they get the support and answers they deserve and justice done".
