Warwickshire Chief Constable Andy Parker has said he was "embarrassed" that his officers had become involved in a heated anti-cuts campaign in the wake of the Plebgate incident.
"My officers got involved in a political campaign which was ill thought-through and has led to a lot of public confidence issues for us," he said.
"I would certainly like to apologise to Mr Mitchell because this added to the already big impact of the Plebgate campaign and it is embarrassing that my force was involved in the way it was."
The Chief Constable of West Mercia Police has offered an "unreserved apology" to ex-Chief Whip Andrew Mitchell over the 'Plebgate' meeting.
West Mercia Police chief constable has overturned a ruling that three officers who met Andrew Mitchell had no case to answer for misconduct.
