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 31,000 officers, 14,000 police staff, 414 traffic wardens and 4,000 Police Community Support Officers (PCSOs) as well as being supported by over 2,500 volunteer police officers in the Metropolitan Special Constabulary (MSC) and its Employer Supported Policing (ESP) programme. The Metropolitan Police Services covers an area of 620 square miles and a population of 7.2 million.
