The 2026 United Left primary is a primary election in France scheduled for 11 October 2026, which aims to select a joint candidate for the 2027 French presidential election from L'Après, Les ÃÂcologistes, Debout!, and Génération.s. The Socialist Party (PS) may or may not join the primary, depending on their results from the 2026 municipal elections. La France Insoumise and Place Publique will not participate.
The primary was jointly initiated by Marine Tondelier, the national secretary of the Ecologists, Olivier Faure, first secretary of the Socialist Party, Lucie Castets, the New Popular Front's candidate for Prime Minister in 2024, François Ruffin, the national coordinator of Debout!, and Clémentine Autain, one of the co-founders of L'Après, on 15 November 2025.
This primary is not unanimously supported by the participants of the New Popular Front (the left-wing coalition for the 2024 legislative elections):
The primary election is scheduled for 11 October 2026 and will be held in person and online. A polling station will be set up in each canton of metropolitan France and in the overseas departments and regions.
