Bristol West was a borough constituency represented in the House of Commons of the Parliament of the United Kingdom since 2015 by Thangam Debbonaire of the Labour Party.

Following the completion of the 2023 Periodic Review of Westminster constituencies, the seat was reduced in size, with part of the Bishopston and Ashley Down ward being transferred to Bristol North West, and Lawrence Hill and Easton wards to Bristol East.

[2][3][4] More urban since boundary changes in 2010, the seat retains a high proportion of the city's most garden-rich, grandest houses and landscaped civic parks in affluent suburbs such as Clifton and Redland.

1974–1983: as above plus District 1983–1997: The City of Bristol wards of Ashley, Bishopston, Cabot, Clifton, Cotham, Henleaze, Redland, and Stoke Bishop.

That win, declared on the night of the election at 3:15 am, took Labour over the threshold of 330 seats required for an overall majority in the new House of Commons.

This Liberal Democrat success was similar to those in other seats with a large student population, such as Cambridge, Manchester Withington, Leeds North West and Cardiff Central.

[10] As a result of the formation of a Brexit 'Unite to Remain' pact between the Liberal Democrats, the Green Party and Plaid Cymru prior to the 2019 snap election, the Liberal Democrats agreed to withdraw from the Bristol West election in favour of the Green Party.
