Overview
- Olivier Faure secured a fourth term as first secretary with 51.15% of delegate votes, narrowly outpacing Nicolas Mayer-Rossignol.
 - Efforts to draft a unifying synthesis collapsed when Mayer-Rossignol’s faction insisted on inserting a clause ruling out any national alliance with LFI.
 - PS deputy Jérôme Guedj’s on-stage denunciation of Jean-Luc Mélenchon as “a salopard antisémite” heightened internal tensions and drew demands for apologies from LFI.
 - Faure reiterated that the party will not back Mélenchon in the 2027 presidential contest but refused to categorically bar cooperation with LFI in crisis scenarios.
 - Prominent figures such as Boris Vallaud and Raphaël Glucksmann remain divided over preserving a distinct socialist identity versus pursuing a broader left-wing coalition ahead of 2027.
