The Police and Crime Commissioner of Avon and Somerset has received a letter from Her Majesty's Chief Inspector of Constabulary in support of a Nick Gargan resignation.
The letter - which was sent to Sue Mountstevens - could help decide the fate of her Chief Constable, who was found guilty of eight counts of misconduct by an independent panel.
In the letter Sir Tom Winsor confirms he agrees the Chief Constable of Avon and Somerset should go. Nick Gargan has 14 days to respond.
Commissioner Mountstevens told us the situation had been "damaging for everyone concerned".
It has emerged that 24 out of 25 Avon and Somerset police superintendents voted 'no confidence' in Nick Gargan.
Today, the Chief Constable of Avon and Somerset Police, will learn his fate at a sanction hearing.
Three former Avon & Somerset Police Chief Constables have written to the Police and Crime Commissioner asking Nick Gargan to resign.
