Les Républicains secured the largest share of seats in the September 27, 2026, partial renewal of 178 Senate seats, finishing with 124 after modest losses from their prior 131, well ahead of the Union Centriste at around 63 and the Socialists near 62. Their position stems from entrenched support among the local elected officials who form the indirect electoral college, combined with alliances that preserved a working majority alongside centrist partners despite erosion from National Rally advances. The far-right grouping reached 15 seats for its first parliamentary group but started from a small base and could not displace the right-center bloc. Final group affiliations were confirmed in early October with no further shifts large enough to alter the ranking. Late adjustments in overseas territories or unexpected switches remain the only narrow paths that could theoretically narrow the gap.
