Lecornu, 39, is the youngest defense minister in French history and architect of a major military buildup through 2030, spurred by Russias war in Ukraine. A former conservative who joined Macrons centrist movement in 2017, he has held posts in local governments, overseas territories and during Macrons yellow vest great debate, where he helped manage mass anger with dialogue. He also offered talks on autonomy during unrest in Guadeloupe in 2021. His rise reflects Macrons instinct to reward loyalty, but also the need for continuity as repeated budget showdowns have toppled his predecessors and left France in drift.Legislators toppled Lecornus predecessor Francois Bayrou and his government in a confidence vote on Monday, a new crisis for Europes second-largest economy. Bayrou gambled that lawmakers would back his view that France must slash public spending to rein in its huge debts. Instead, they seized on the vote to gang up against the 74-year-old centrist who was appointed by Macron last December. The demise of Bayrous short-lived minority government heralds renewed uncertainty and a risk of prolonged legislative deadlock for France as it wrestles with pressing challenges, including budget difficulties and, internationally, wars in Ukraine and Gaza and the shifting priorities of U.S. President Donald Trump. Drafting a budget will be a top priority for Lecornu, and normally a new prime minister would form the new government before negotiating the national spending in Parliament. However, Macron has asked Lecornu to consult with all of the political parties in Parliament first to try to agree on a budget before assembling his team.The prime ministers action will be guided by the defense of our independence and our power, serving the French and the political and institutional stability for the unity of our country, Macron said in a statement.
