The Metropolitan Police Service (MPS), commonly known as the Metropolitan Police, Met Police, or the "Met", is the territorial police force responsible for law enforcement and crime prevention within Greater London. In addition, it is responsible for specialised tasks throughout the United Kingdom, such as dealing with counter-terrorism throughout the UK, and the protection of certain individuals, including the monarch, royal family, governmental officials, and other designated figures. It is also referred to as an eponym as "Scotland Yard" or "the Yard", after the location of its original headquarters in Great Scotland Yard, Whitehall, in the 19th century. The Met is presently headquartered at New Scotland Yard, in a building situated on the Victoria Embankment.
