The Commissioner is regarded as the highest ranking police officer in the United Kingdom, although 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.
