Main article: 2024 French legislative election
Following the first round of the 2024 French legislative election on 30 June 2024, runoff elections in each constituency where no candidate received a vote share greater than 50 percent were scheduled for 7 July. Candidates permitted to stand in the runoff elections needed to either come in first or second place in the first round or achieve more than 12.5 percent of the votes of the entire electorate (as opposed to 12.5 percent of the vote share due to low turnout).
