France's previous and now new Prime Minister Sebastien Lecornu has vowed to end the country's deepening political crisis and deliver a budget for the end of the year. But with a fractured parliament and no clear majority, forming a stable government over the weekend will once again be a major challenge. The far-right National Rally slammed Lecornu's reappointment as a "bad joke," while left-wing leaders renewed calls for change. With President Emmanuel Macron's power weakened, Sebastien Lecornu's success could prove crucial to his political future.
