Élisabeth de Maistre Wins Legislative Election in Boulogne-Billancourt, Securing Seat for Les Républicains

De Maistre's victory returns a historically conservative seat to the right, defeating Horizons' candidate in a low-turnout election.

Élisabeth de Maistre, a candidate for Les Républicains, won the legislative partial election in Boulogne-Billancourt with 59.65% of the vote, defeating Antoine de Jerphanion of Horizons.
The election was held to fill the seat vacated by Stéphane Séjourné (Renaissance), who stepped down after being appointed as a European Commissioner.
De Maistre’s win marks a significant gain for Les Républicains, reclaiming a seat they lost in 2017 during the rise of Macron’s political movement.
Voter turnout was historically low, with only 25.82% of eligible voters participating in the second-round runoff.
De Maistre has a background in law and local politics, having served as an assistant parliamentary aide and deputy mayor in Boulogne-Billancourt, focusing on family and early childhood policies.
