- The Socialist Party’s First Secretary Olivier Faure and MEP Raphaël Glucksmann are preparing to face off in a primary scheduled for October.
- Raphaël Glucksmann has already made his candidacy official and is enjoying favourable polling momentum, while Olivier Faure is expected to announce shortly.
- The internal consultation held in Blois highlighted strategic divisions within the party, particularly regarding its relationship with La France Insoumise.
- Several other figures, including Jérôme Guedj and Philippe Brun, are maintaining their candidacies to offer an alternative to the two favourites.
A primary at the heart of the summer universities

The Socialist Party’s summer universities, held in Blois, served as the stage for the first manoeuvres ahead of the 2027 presidential election. At the centre of the discussions, the upcoming social-democratic primary, scheduled for October, is crystallising ambitions. The internal competition has now been launched, forcing party members and officials to take a stand on the political lines embodied by the various contenders.
A rivalry between two figureheads
Attention is primarily focused on the duel between First Secretary Olivier Faure and MEP Raphaël Glucksmann. While the latter has already officially entered the race, the former’s declaration is imminent. Tensions have emerged on the ground, illustrating a quiet animosity between the two camps. While Raphaël Glucksmann’s supporters highlight his recent electoral weight, Olivier Faure’s camp points to his role in the essayist’s political rise and questions the clarity of the Place Publique programme. This internal duel reflects persistent disagreements over strategy, particularly regarding the position to take towards La France Insoumise.
The challenge of internal cohesion
Despite fears of a public rift, party leaders are calling for a respectful vote. The stated objective is to avoid any loss of credibility for the movement ahead of the presidential deadline. However, the practicalities of the primary are themselves the subject of technical discussions, as evidenced by the disagreement over the number of televised debates required to compare ideas. The challenge for the Socialist Party remains maintaining unity after the result of the vote, regardless of the winner.

Alternative candidates lying in wait
The face-off between the two favourites is not considered a foregone conclusion by all players. Figures such as Jérôme Guedj, Philippe Brun, and Ségolène Royal intend to influence the debates. These « outsider » candidates defend various lines, ranging from the republican left to a desire to champion more grassroots themes. For them, the primary, although designed to be semi-closed, remains an open election where programmatic confrontations could reshuffle the deck. The success of this period will depend on the participants’ ability to generate genuine interest among voters.
