The Attorney General has guaranteed that anything said by witnesses to the Grenfell Tower Inquiry will not be used to prosecute them over the fire.

Suella Braverman wrote to the inquiry chairman, Sir Martin Moore-Bick, confirming that the Government had accepted the request from staff involved in refurbishing the high-rise block with flammable materials.

Lawyers from firms including the main contractor and architects involved in revamping the 24-storey tower in west London submitted the last-minute bid for the pledge when the inquiry reopened in January, causing proceedings to be delayed.

Without the Government-backed guarantee, many witnesses had threatened to stay silent by claiming the legal right of privilege against self-incrimination.

Survivors' group Grenfell United said it was a "sad day" following the Attorney General's decision to grant an undertaking to the Inquiry.
