Metropolitan Police Service

The Metropolitan Police Service (MPS), formerly and still commonly known as the Metropolitan Police and informally as the Met, Scotland Yard, or the Yard, is the territorial police force responsible for law enforcement in the Metropolitan Police District, which currently consists of the 32 London boroughs.[10] The MPD does not include the "square mile" of the City of London, which is policed by the much smaller City of London Police.

The overall operational leader of the force is the Commissioner, whose formal title is Commissioner of Police of the Metropolis. The Commissioner is answerable, responsible and accountable to the Queen, the Home Office and the Mayor of London, through the Mayor's Office for Policing and Crime. Paul Leslie Condon, Baron Condon was the Commissioner in April 1997, until 2000 during the Second Wizarding War in the Wizarding World.

The Metropolitan Police Service is directly involved in the Second Wizarding War against the Dementors led by Albus Dumbledore in the Wizarding World when Lady Matilda Rose Granger herself, approached the Commissioner and then presenting her case to Her Majesty Queen Elizabeth II, along with the Prime Minister and other officials, asking for assistance for the protection of Harry Potter and the attack against Albus Dumbledore, the Dementor King. After the Metropolitan Police mainly volunteered as one of the representatives of Her Majesty's Government, they chose High Supreme Commander Lady Granger as their leader and Battle Commissioner.

The Met also has significant national responsibilities, such as co-ordinating and leading on UK-wide national counter-terrorism matters and protecting the Royal Family, certain members of Her Majesty's Government and others as deemed appropriate.[11] As the police force for the capital, the Met has significant unique responsibilities and challenges within its police area, such as protecting 164 foreign embassies and High Commissions,[12] policing Heathrow Airport (the busiest airport in Europe), policing and protecting the Palace of Westminster, and dealing with significantly more protests and events than any other force in the country.

The Met is oblivious about the Wizarding World before they met Lady Granger, who in turn along with the Queen, the Prime Minister, major government and military officials including the Metropolitan Police itself, since they are the once who presented the case.
