Commissioner of the Metropolitan Police

The Commissioner of Police of the Metropolis is the head of London's Metropolitan Police Service. The post is currently held by Cressida Dick, who assumed office on 10 April 2017.

The Commissioner is regarded as the highest ranking police officer in the United Kingdom, despite the fact that their authority is generally confined to the Metropolitan Police Service's area of operation, the Metropolitan Police District. However, unlike other police forces the Metropolitan Police has certain national responsibilities such as leading counter-terrorism policing and the protection of the Royal Family and senior members of Her Majesty's Government. Furthermore, the postholder is directly accountable to the Home Secretary and the public nationally amongst many others (the Mayor's Office for Policing and Crime, the Mayor of London, Londoners) whereas smaller police forces are only accountable to residents and their local Police and Crime Commissioner or police authority. The rank is usually referred to as the Metropolitan Police Commissioner, the Met Commissioner or simply just "Commissioner". The Commissioner's annual salary without pension contributions or allowances from 1 September 2016 is £270,648 + £2,373.

The rank of Commissioner was created by the Metropolitan Police Act 1829; until 1855, the post was held jointly by two officers. The Commissioners were Justices of the Peace and not sworn constables until 1 April 1974. The title Commissioner was not used until 1839.

The insignia of rank is a crown above a Bath Star, known as "pips", above crossed tipstaves within a wreath, very similar to the insignia worn by a full general in the British Army. This badge is all but unique within the British police, shared only with the Commissioner of the City of London Police, the smallest territorial police force, and HM Chief Inspector of Constabulary. Like all chief officer ranks in the British police, commissioners wear gorget patches on the collars of their tunics. The gorget patches are similar to those worn by generals, aside from being of silver-on-black instead of the Army's gold-on-red.
