Leicester West is a constituency^{[n 1]} represented in the House of Commons of the UK Parliament since 2010 by Liz Kendall of the Labour Party.^{[n 2]} Along with the other two Leicester seats, it was held by Labour at the 2017 general election. Since its creation in 1918 the seat has sided with parties from the left wing of politics.

1983–2010: The City of Leicester wards of Abbey, Beaumont Leys, Mowmacre, New Parks, North Braunstone, Rowley Fields, St Augustine's, Westcotes, and Western Park.

Leicester West is the whitest of the three Leicester constituencies, and the one with the highest proportion of social housing. Some areas of the seat, such as Braunstone and Beaumont Leys, are made up of large local authority estates, and around 30% of the housing is council- or housing association-owned, the second-highest in the Midlands. The centre of the seat, the Westcotes area, is more inner-city in character and is popular with young professionals and students.^[3]

Historically this used to be the safest Labour seat in Leicester—in the 1983 general election it was the only one to remain in Labour hands. However, the high Asian populations in Leicester South and Leicester East have pushed them away from the Conservative Party; while Leicester West is still a safe Labour seat, represented by that party since the Second World War, it is the most marginal of the three Leicester seats.^[3] While it did, like the other two Leicester seats, see a significant swing to Labour in 2017, unlike the other two seats Liz Kendall's majority was not a record high for the constituency.

As of 2009, in the depths of the late-2000s recession, the constituency had the fourth-highest level of unemployment in Britain, with 13.8% of residents registered unemployed. Most of the unemployment is concentrated in areas such as Braunstone, which is traditionally one of the most deprived parts of the city.^[4]

In 1950, the seat was replaced by the constituencies of Leicester North West and Leicester South West, until 1974. In that period, Leicester North West was represented by Barnett Janner until 1970, and then by his son Greville Janner.
