French President Emmanuel Macron on Tuesday appointed Sebastien Lecornu as prime minister a day after parliament forced out his predecessor, marking the fifth change of head of government in less than two years.

Lecornu, 39, a close political ally who most recently served as minister of armed forces, is expected to steer a minority government that preserves Macron’s pro-business economic agenda — including past tax cuts for companies and the wealthy and a higher retirement age — while attempting to build parliamentary consensus on a 2026 budget that has become the central political flashpoint.

Macron was compelled to seek a new prime minister after lawmakers ousted Francois Bayrou nine months into his tenure, reacting to plans for aggressive spending cuts designed to rein in a deficit that stands at nearly twice the European Union ceiling of 3% of GDP. Lecornu’s nomination signals Macron’s determination to press ahead with his economic legacy rather than shift left to placate centre-left parties that have vowed to roll back some of his reforms.

Lecornu’s immediate task will be to secure support for a 2026 budget that tackles mounting public debt without undoing policies Macron deems necessary to attract investment. The political arithmetic is difficult: Macron’s centrist camp does not command a majority in the National Assembly, and the president and his new government will likely need tacit backing from Marine Le Pen’s far-right National Rally on key votes. Officials from the National Rally have indicated they could provide limited support if Lecornu is confirmed as premier, while also warning against tax increases on what they describe as "hard-working people."

Lecornu built his political career early and across the spectrum. He campaigned for Nicolas Sarkozy as a teenager, became a mayor in Normandy at 18 and served as Sarkozy’s youngest government adviser at 22. He left the conservative Les Republicains to join Macron’s centrist movement during the president’s first successful bid for the Élysée in 2017 and helped run Macron’s re-election campaign five years later.

As defence minister, Lecornu oversaw increases in defence spending and played a role in shaping European thinking on security guarantees for Ukraine in the event of a negotiated peace with Russia. He has at times reached out to figures on the right, including a private dinner last year with Marine Le Pen and National Rally chief Jordan Bardella, a contact that analysts say could ease short-term cooperation on major votes.

The nomination carries risks for Macron. Polls show voter appetite for change, and opposition parties on the left have promised to reverse several of Macron’s flagship measures. Socialist lawmakers oppose measures such as the elimination of a wealth tax and the increase in retirement age. Labor unions and left-wing groups have called nationwide protests under the banner "Block Everything," with demonstrations expected to be widespread on Wednesday and potentially disruptive to transport and public services.

Lecornu must now present a program to the National Assembly and seek confidence for his government while negotiating a budget that satisfies creditors and addresses rising debt. The move to appoint a loyalist underscores Macron’s priority to defend his economic reforms, but it leaves the administration reliant on fragile parliamentary arrangements and facing immediate public opposition.
