Councils would be unlikely to use products from any company that fails to cooperate fully with the Grenfell Tower inquiry, the Local Government Association (LGA) has warned.

This week the inquiry forwarded the request to grant witnesses immunity from having any evidence they give being used against them in future prosecutions to the Attorney General.

The LGA said it was ‘extremely' concerned about the request.

Building safety spokesman for the LGA, Lord Porter, said: 'We are concerned that either granting this request or, if it is denied, any subsequent refusal by witnesses to answer the inquiry's questions, will frustrate justice and hamper attempts to learn the lessons of Grenfell - lessons which are all the more urgent given the large number of buildings still covered in dangerous cladding and the subsequent blanket of fear that remains imposed on those who live in them.

'The LGA urges the Attorney General to do everything in his power to ensure the truth comes out in a manner that guarantees those who have a criminal case to answer face justice and does not jeopardise civil litigation against those responsible for rendering buildings unsafe.

'It would be hard to imagine that in the future any council would allow the use of any products manufactured by any company who did not cooperate fully with the inquiry.'
