(Christophe Ena | Pool AP)PARIS — French Prime Minister François Bayrou presented his resignation to President Emmanuel Macron Tuesday morning, after lawmakers voted down his economic plans in a no-confidence ballot on Monday. It will be the fourth time he picks a new head of government in just a year and a half — and it won’t be easy, says French political journalist Thierry Arnaud. Because in both terms, he ran on a platform of keeping the National Rally at bay and doing whatever it takes. It’s the most popular political party in France, with a third of polled voters regularly saying they would cast a ballot for it. As France awaits its next prime minister, Bacharan says many people are in despair over the uncertainty this has brought on the country.
