Wimbledon is a constituency represented in the House of Commons of the UK Parliament. Since 2005, the seat has been represented by Stephen Hammond of the Conservatives. History The area was created by the Redistribution of Seats Act 1885 and had lay in Mid Surrey that elected two MPs. The constituency covered great bounds, skirting around Croydon to its south to reach Caterham, Warlingham, Chelsham and Farleigh in the North Downs and bearing formal alternate titles of the Wimbledon Division (of Surrey) and the North East Division of Surrey which in all but the most formal legal writing was written as North East Surrey. An Act reduced the seat in 1918 to create the Mitcham seat in the south-east; another in 1950 created Merton and Morden in the south. Political history Since 1885 the seat has elected Conservative MPs except from 1945 to 1950 and 1997–2005, when the Labour candidate won the seat during that party's national landslide years.

In the local elections in 2018, Liberal Democrat councillors were elected for the wards of Trinity and Dundonald for the first time in the borough's history, with a further first time win for the Liberal Democrats in a by-election in the Cannon Hill ward in 2019. In 2010, the second-placed candidate was a Liberal Democrat. The national collapse in the Liberal Democrat vote at the 2015 election meant that the Liberal Democrats did not return to 2nd place until 2019, when they did so with a 22.7% upswing in their vote. The seat is now one of the most marginal in the country and a top Liberal Democrat target and Conservative defence for the next general election.
