Overview

• Olivier Faure secured 50.9 percent of votes on June 6 against Nicolas Mayer-Rossignol’s 49.1 percent, clinching a fourth term as party leader.
• The narrow margin signals persistent internal strife over the party’s alliance with La France Insoumise, including its radical wing.
• Since Faure took charge in 2018, the PS has climbed back from marginalization by doubling its parliamentary seats to 66 through the NUPES alliance in 2024.
• Faure advocates a wide left coalition “from Ruffin to Glucksmann,” promoting cooperation with moderate LFI defectors despite Mélenchon’s distancing.
• Delegates will meet in Nancy mid-June to test Faure’s authority and chart the Socialist strategy for the 2027 presidential contest.
