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 along with the Merton and Morden Urban District, all formerly within Surrey. The borough derives its name from the historic parish of Merton, which was centred around the location now known as South Wimbledon. The local authority is Merton London Borough Council.
Merton covers a total area of about 14.52 square miles. The borough is also served by various 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 industrial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the largest. Other smaller sized centres include Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Every year, Wimbledon, one of the four tennis Grand Slam tournaments, is held 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 occasion to take place in the United Kingdom, attracting over 200000 visitors for the duration of the Wimbledon fortnight.
