The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon as well as the Merton and Morden Urban District, all formerly inside Surrey. The borough derives its name from the historic parish of Merton, which was centred on the location now generally known as South Wimbledon. The local authority is Merton London Borough Council.
In line with population estimates made during 2014, the borough has a permanent population of about 203515 individuals. The borough is also served by numerous London Tramlink stops from Wimbledon, which goes to Croydon, New Addington, Elmers End and Beckenham. It is the only London Borough which has tube, rail and tram services.
The key commercial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the biggest. Other smaller centres consist of Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Each year, Wimbledon, one of the four tennis Grand Slam tournaments, takes place at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The occasion happens over a fortnight at the end of June and beginning of July and it's the biggest annual sporting event to take place in the UK, attracting over 200000 visitors for the duration of the Wimbledon fortnight.
