In short: Appointed Prime Minister in September 2025, Sébastien Lecornu faced immediate political turbulence. After resigning just 26 days into his first term, he was reappointed by President Emmanuel Macron, navigating a series of no-confidence motions and budget crises to secure his position as the leader of the French Fifth Republic.

Sébastien Lecornu, born in 1986, has long been a fixture in French politics, moving from local governance in Eure to high-level ministerial roles. Before his rise to the premiership, he served as Minister of the Armed Forces from 2022 to 2025, where he oversaw significant military expansion. His tenure included the presentation of the 2024–2030 Military Programming Law, which aimed to double annual defense spending to 69 billion euros by 2030, alongside efforts to modernize the French nuclear arsenal and increase troop numbers.

His appointment as Prime Minister on 9 September 2025 followed the collapse of the Bayrou government. Lecornu’s initial cabinet lasted only 26 days before he resigned amid intense political pressure. However, President Macron reappointed him on 10 October 2025. This period was marked by high-stakes legislative maneuvering, including the suspension of the 2023 pension reform until the 2027 presidential election to win support from the Socialist Party and survive multiple no-confidence motions.

Lecornu’s political identity is complex, blending Gaullist and Séguinist roots with a pragmatic, sometimes contradictory, approach to policy. While he has historically held socially conservative views—opposing same-sex marriage in 2012 and criticizing welfare policies—he has proven adept at making concessions to the left, such as securing budget votes through social housing and student meal initiatives. His career reflects a tension between his ideological right-wing origins and the necessity of governing a fragmented National Assembly.
