The French presidency said in a statement on Monday that President Emmanuel Macron has accepted his close ally’s resignation.
Appointed nearly a month ago, Lecornu had come under increasing pressure in recent weeks as he struggled to pass a budget through France’s fractured parliament amid a debt crisis.
He named his ministers on Sunday evening but quit his post hours later, making his government one of the shortest lived in French history.
The new cabinet was due to hold its first meeting on Monday afternoon, but despite Lecornu’s promises to “break” with the strategy of his unpopular predecessor François Bayrou, the lineup of new ministers angered opponents and allies alike. Many figures in Lecornu’s cabinet had served in the previous government.
“I was ready to compromise, but each political party wanted the other political party to adopt its entire programme,” Lecornu said outside the prime minister’s office.
