The senatorial elections in the Bouches-du-Rhône department have led to a major reshuffling of local political representation, with notable discord on the right. Initially, Les Républicains (LR), a major conservative party, backed a centrist list led by outgoing UDI senator Brigitte Devésa and Renaud Muselier, the president of Renaissance—a group that previously belonged to LR and is now in the PACA region. This list received the official endorsement of LR. However, Valérie Boyer, an outgoing LR senator who had been offered a third position on the Devésa/Muselier list, decided instead to run on her own list, supported by Bruno Retailleau, the president of LR. This move was met with disapproval from Hervé Marseille, president of the centrist group, and created internal tensions within the right-wing alliance. Gérard Larcher, president of the Senate and also a member of LR, had planned to visit Aix-en-Provence to support the Devésa/Muselier list but canceled his trip at the last moment. In a letter, he reminded candidates that the Devésa/Muselier list had been officially "invested" by the "national investment commission" of LR, with the support of the senatorial majority. However, Bruno Retailleau had personally backed Valérie Boyer’s competing list. The cancellation of Larcher’s visit added to the existing tensions. Renaud Muselier expressed disappointment with Bruno Retailleau’s support for Boyer, stating that Retailleau, as party leader, was acting against the national investment commission, for which he had previously given his agreement. Muselier also noted that Retailleau had once praised him, even recalling that he had helped Valérie Boyer during the funeral of Bernadette Chirac in June. The division on the right was further complicated by the candidacy of Hervé Granier, the mayor of Gardanne, who ran independently but did not win a seat. Despite these internal conflicts, the right-wing coalition retained its seat, though it was expected to lose between 3 and 10 seats, potentially shifting the balance of power toward the centrists. On the left, the united left list led by Jérémy Bacchi (PCF), followed by Marie-Arlette Carlotti (socialist) and Guy Benarroche (ecologist), secured three seats, confirming their positions without gaining a fourth. The left criticized the right’s internal divisions, claiming they cost them an additional seat. At the far right, the Rassemblement National (RN) secured two seats, with Marie-Pierre Callet, an ex-LR who switched to RN this year, and Fabien Bravi winning seats. This result was seen as a confidence boost for the RN and a step toward the presidential election. Renaud Muselier, who had to take the second position on the Devésa list due to a rule requiring alternation between men and women, finally entered the Senate, marking a significant milestone in his political career. Valérie Boyer, despite running independently, retained her seat, while Hervé Granier did not achieve the same success.
