The City of London Police is the territorial police force responsible for law enforcement within the City of London, including the Middle and Inner Temples. The force responsible for law enforcement within the remainder of Greater London, outside of the City, is the Metropolitan Police Service, a separate organisation. The City of London, which is now primarily a financial business district with a small resident population but a large commuting workforce, is the historic core of London, and has an administrative history distinct from that of the rest of the metropolis, of which its separate police force is one manifestation.
