The Metropolitan Police Service (MPS) is the territorial police force responsible for Greater London, excluding the City of London. Established in 1829 by Sir Robert Peel, the MPS aims to maintain law and order, prevent crime, and protect the public. It is one of the largest police forces in the world, employing thousands of officers and staff. The MPS operates under the jurisdiction of the Mayor of London and the Home Office. Its responsibilities include responding to emergencies, conducting investigations, and engaging with local communities to enhance safety and security. The MPS also collaborates with other agencies to address complex issues like terrorism and organized crime.
