2022 Southend West by-election

A by-election was held on 3 February 2022 in the parliamentary constituency of Southend West following the murder of the Conservative MP Sir David Amess on 15 October 2021. Amess had been the MP for the constituency since 1997, and previously represented the nearby seat of Basildon from 1983 to 1997. Similarly to the 2016 Batley and Spen by-election—held after Labour MP Jo Cox was murdered—the major opposition parties declined to stand out of respect for Amess. The Conservative candidate Anna Firth won the by-election with 86% of the vote, with a turnout of 24%. No other candidate reached the 5% threshold to save their election deposit.
