France’s Prime Minister Resigns After Forming Cabinet

Prime Minister Sébastien Lecornu resigned on Oct. 6, 2025 — less than a month into his tenure and less than 24 hours after naming a new government — after losing the support of a key conservative coalition ally over his cabinet picks. President Emmanuel Macron accepted the resignation, leaving caretakers in place while Macron must either appoint a new prime minister or dissolve the National Assembly and call new legislative elections; the shock prompted market volatility, with the CAC‑40 falling nearly 2%.
