Overview
- Voters in the 5th, 6th and 7th arrondissements head to the first round on September 21 after the Conseil constitutionnel annulled the 2024 result.
- Former prime minister Michel Barnier runs for Les Républicains and is widely viewed as the frontrunner, with 5th arrondissement mayor Florence Berthout as his substitute.
- The left has rallied behind Socialist Frédérique Bredin, who aims to push the race to a September 28 runoff after a strong left showing in 2024.
- The field counts 17 candidates, including RN’s Thierry Mariani and Reconquête’s Hilaire Bouyé, additions that divide the right but are not seen as major threats in this seat.
- A Barnier win would bolster centre‑right claims to this affluent constituency and offer a signal for LR ahead of the 2026 Paris municipal campaign.
