Glucksmann wins PS primary, rejects LFI alliance, reshaping French left

Raphaël Glucksmann won the PS-Place Publique primary in the first round, consolidating social-democratic leadership and explicitly ruling out an alliance with Jean-Luc Mélenchon's La France insoumise. This sharpens the split within the French left ahead of the 2027 presidential election, with Mélenchon seeking to absorb social democrats. The outcome signals a potential realignment of the left, but the electoral impact remains uncertain.
