France stumbled into the holiday season with its fourth prime minister this year, no new government and only an emergency rollover budget to get it through the first months of 2025. François Bayrou is a wily veteran, a 73-year-old fellow centrist whom President Emmanuel Macron appointed to form a government on December 13th. He hopes to broaden the coalition formed by Michel Barnier, his conservative predecessor, who was toppled by parliament on December 4th. Even if Mr Bayrou manages to recruit more widely, however, he will struggle to put in place what France really needs: a stable, lasting government that can begin to get its dismal public finances under control.
