'Plebgate': Met Police reject PC's resignation 22 January 2014 Last updated at 16:06 A police officer who admitted misconduct in the "plebgate" affair has had his offer to resign refused. PC Keith Wallis admitted pretending to witness the 2012 row between the then-cabinet minister Andrew Mitchell and the police, and now may face prison. When he entered a guilty plea to misconduct in public office at the Old Bailey, it emerged he had also offered to resign from the Metropolitan Police. But the Met said its deputy commissioner had the right to refuse. "The deputy commissioner has refused to accept Pc Wallis's resignation and he will face a misconduct board in the coming weeks," Scotland Yard said in a statement.
