Overview
- Sébastien Martin, a divers droite candidate, defeated RN's Arnaud Sanvert in Saône-et-Loire's 5th constituency by-election with 58.6% of the vote.
- The by-election was triggered by the invalidation of Sanvert's 2024 election due to voting irregularities.
- Martin benefited from a broad republican front, with calls from left-wing and centrist candidates to block the RN.
- The left-wing coalition's failure to unite resulted in their exclusion from the second round, with fragmented support among LFI and PS candidates.
- Martin has pledged to join the Droite républicaine group in the Assemblée nationale, emphasizing his commitment to representing his constituents as a 'free deputy.'
