Mitcham and Morden is a constituency in Greater London represented in the House of Commons of the UK Parliament since 1997 by Dame Siobhain McDonagh of the Labour Party.

Constituency profile Mitcham and Morden is a constituency in the Borough of Merton in Greater London, located around south of the centre of London. It covers the neighbourhoods of Mitcham, Lower Morden, Pollards Hill, Colliers Wood and part of central Morden.

This is a relatively dense suburban constituency that was mostly developed in the interwar period and consists mainly of terraced houses and low-rise flats. Mitcham retains some village-like characteristics with many green spaces including the large Mitcham Common, although there is some deprivation here with council housing developments and industrial estates. Mitcham contains two train stations and is connected to the Tramlink network, although only Morden is served by the London Underground. Lower Morden is the most affluent area of the constituency with many large semi-detached properties. House prices across the constituency are generally lower than the rest of London but higher than the national average.

Mitcham and Morden has a large working-age population and relatively few retirees. In general, residents have average levels of education and homeownership. Levels of household income and child poverty are similar to the rest of London. A high proportion of residents work in the retail, education and construction sectors, and the percentage of residents claiming unemployment benefits is high.

White people made up 52% of the population at the 2021 census. Around one-third of the White population are of non-British origin, including large Polish and South African communities. Asians were the largest ethnic minority group at 21%, many of whom were of Sri Lankan origin. Black people were 16% of the population, mostly concentrated in Pollards Hill where they made up around one-third of residents.

At the local borough council, almost all seats in the constituency are represented by the Labour Party, although some Liberal Democrats were elected in Lower Morden. An estimated 54% of voters in Mitcham and Morden supported remaining in the European Union in the 2016 referendum, a lower percentage than the rest of London but higher than the UK-wide figure of 48%.

History The constituency was created in 1974 from the former seats of Mitcham and Merton & Morden.

Between 1974 and 1982 it was represented by Bruce Douglas-Mann who was elected as a Labour MP but defected in 1982 to the Social Democratic Party (SDP). Douglas-Mann was the sole SDP defector to resign his seat; he sought immediate re-election.

In the by-election Douglas-Mann triggered in May 1982, during the Falklands War, Angela Rumbold (Con) was elected. Rumbold's gain was the last time the Conservative Party would gain (as opposed to hold) at a by-election until 22 May 2008 when Edward Timpson won the Crewe and Nantwich by-election.

At the 1997 general election the seat was won by the Labour Party's Siobhain McDonagh. At the 2001, 2005 and 2010 General Elections, she was re-elected, in the latter election polling the 26th highest share of the vote for the party of the 631 seats contested.

The 2015 re-election of McDonagh made the seat the 41st safest of Labour's 232 seats by percentage of majority and 14th safest in the capital. The seat is one of the capital's two seats in which its majority in 2015 surpassed the Labour Party's landslide 1997 victory (the other being Ilford South).
