Pierre-Henri Carbonnel, candidate supported by the Rassemblement national (RN) and the Union des droites pour la République (UDR), won the partial legislative election in the first constituency of Tarn-et-Garonne with 52.06% of the votes. He succeeds Brigitte Barèges, who was declared ineligible due to irregularities in her campaign financing. This victory, hailed by Éric Ciotti and Jordan Bardella, highlights the union of the right without altering the balance in the National Assembly.
The partial legislative election took place on Sunday, October 12, 2025, in the first constituency of Tarn-et-Garonne, following Brigitte Barèges' resignation in July. The former mayor of Montauban had been declared ineligible by the Constitutional Council for irregularities in her campaign financing during the 2024 snap elections. Pierre-Henri Carbonnel, her former substitute and a 35-year-old farmer, represented the UDR, a party founded by Éric Ciotti after leaving the Républicains (LR), in alliance with the RN.
In the first round on October 5, Carbonnel secured 29.25% of the votes, ahead of socialist Cathie Bourdoncle (24.30%). An RN dissident received 7.34%, while LR candidate Bernard Pécou got 17.55%. In the second round, Carbonnel won with 52.06% of the votes against 47.8% for Bourdoncle, vice-president of the departmental council and backed by the PS, PRG, Carole Delga, and Valérie Rabault.
"Magnificent victory," reacted Éric Ciotti on X, seeing in this result "the advent of the union of the people of the right in the country." The new deputy stated from Montauban: "We see that the Union of the right is on the march. I hope that in Paris, they will know how to draw the consequences." Jordan Bardella, RN president, congratulated Carbonnel, stating that the UDR-RN alliance is "the only credible alternative to govern and straighten out France."
Bruno Retailleau, LR leader, had called not to vote for the left, facilitating a partial transfer of LR votes to Carbonnel. Marine Le Pen hailed a victory showing that "alternation is inevitable." This poll, marked by moderate turnout, does not alter the forces in the Assembly but highlights tensions within the republican right.
