Macron appoints Defense Minister Lecornu as France's latest prime minister

French President Macron late Tuesday appointed Defense Minister Sébastien Lecornu as France’s new prime minister and tasked him with immediately trying to get the country's fractious political parties to agree on a budget for one of the world's biggest economies. Lecornu, 39, was the youngest defense minister in French history and architect of a major military buildup through 2030, spurred by Russia’s war in Ukraine. A longtime Macron loyalist, Lecornu is now France's fourth prime minister in barely a year.
