Sébastien Lecornu, born on June 11, 1986, is a French politician currently serving as Prime Minister of France since September 2025. He is positioned on the right of the political spectrum, advocating Gaullist, Séguinist, and socially conservative views. Lecornu began his political career as a parliamentary assistant at age 20 and was elected mayor of Vernon, Normandy, at 28. He also served as President of the Departmental Council of Eure from 2015 to 2017. Lecornu's ministerial career spans multiple key roles: Secretary of State to the Minister of the Ecological and Inclusive Transition (2017–2018), Minister for Local Authorities (2018–2020), Minister of the Overseas (2020–2022), and Minister of the Armed Forces (2022–2025). He joined President Emmanuel Macron's Renaissance party after leaving The Republicans in 2017. Appointed Prime Minister on September 9, 2025, following the collapse of François Bayrou’s government by a no-confidence vote, Lecornu holds the record as the shortest-serving Prime Minister of the French Fifth Republic. He resigned on October 6, 2025, after just 26 days in office amid political opposition and criticism regarding his cabinet's composition and budget stance but continued as caretaker Prime Minister until his reappointment on October 10, 2025[1][2][4][5][7]. Known for his discreet yet steady rise in politics, Lecornu is the longest-serving minister in Macron’s governments, with over eight years of continuous ministerial service. His political approach emphasizes involving local authorities, notably contributing to the "Great National Debate" in 2019 addressing social unrest[2][3].
