The Metropolitan Police Service is famed around the world and has a unique place in the history of policing. It is by far the largest of the police services that operate in greater London (the others include the City of London Police and the British Transport Police). The Royal Parks Constabulary have now become part of the Metropolitan Police Service. Founded by Sir Robert Peel in 1829, the original establishment of 1,000 officers policed a seven-mile radius from Charing Cross and a population of less than 2 million. Today, the Metropolitan Police Service employs 31,141 officers, 13,661 police staff, 414 traffic wardens and 2,106 Police Community Support Officers (PCSOs), and, since the realignment of police boundaries in April 2000, it covers an area of 620 square miles and a population of 7.2million.
