Roland Lescure gets the post of Minister of Economy with the difficult task of delivering a budget.
Several key ministers remain in their previous jobs. This applies to Foreign Minister Jean-Noël Barrot, Interior Minister Bruno Retailleau and Justice Minister Gérald Darmanin.

The new-old government is facing a divided and difficult political situation.
Lecornu, who is Macron's seventh prime minister, was appointed after his predecessor François Bayrou lost a vote of confidence in September.
A political crisis has been ongoing since last year's new elections, called by Macron, which resulted in a parliament divided into three rival blocks.
Lecornu plans to deliver a speech in parliament on Tuesday. At the same time, several parties on the left have threatened to pass a vote of no confidence against the prime minister.
