Jean-Luc Mélenchon

In the second round of the 2026 municipal elections, Jean-Luc Mélenchon's La France insoumise (LFI) won Roubaix, Creil, Vénissieux, and La Courneuve, following Saint-Denis in the first round. However, alliances with the rest of the left failed in the vast majority of cases, including in Toulouse, Besançon, Strasbourg, and Limoges.
