A by-election was held for the United Kingdom Parliament seat of Leicester South on 15 July 2004. It was triggered by the death of Labour Party Member of Parliament (MP) Jim Marshall, who died on 27 May 2004, shortly before the local and European elections in June. The by-election was won by Parmjit Singh Gill of the Liberal Democrats, over-turning a Labour majority of 13,243 votes at the 2001 general election. This by-election was held on the same day as the Birmingham Hodge Hill by-election, which Labour won with a highly reduced majority of just 460 votes (2.3%).
