The Mayor's Office For Policing and Crime

The Mayor's Office for Policing and Crime (MOPAC) is a functional body of the Greater London Authority responsible for oversight of the Metropolitan Police. It came into being on 16 January 2012 at midnight,[1] replacing the Metropolitan Police Authority, as envisaged by the Police Reform and Social Responsibility Act 2011.

The office is headed by the Mayor of London (although the Mayor may appoint a Deputy Mayor for Policing and Crime to act on their behalf) and is held to account by the Police and Crime Committee of the London Assembly. Although the office is responsible for strategic oversight of the Metropolitan Police, all operational policing decisions remain the responsibility of the Commissioner of Police of the Metropolis. The office lacks the power to appoint or dismiss the commissioner.
