PARIS — Prime Minister Michel Barnier of France has returned to his duties after undergoing surgery over the weekend for a cervical lesion. This health update comes from a rare announcement made by his physician.

At the age of 73, Barnier stands as the oldest among the various prime ministers who have served in the modern era of France’s Fifth Republic. He has made his way back to the Hôtel de Matignon, which serves as the official residence for the prime minister. He is slated to lead the weekly Cabinet meeting scheduled for Thursday, as confirmed in a recent statement.

Details regarding the surgery were somewhat limited, but Dr. Olivier Hersan confirmed that the procedure was successful and indicated that analysis results concerning the lesion will be released in the weeks to come.

This surgery occurs during a crucial time in Barnier’s political career. He was appointed by President Emmanuel Macron just last month, taking over the role from Gabriel Attal, who held the position for a short time and was noted as the youngest prime minister in France’s history at just 35 years old.

Barnier’s leadership follows a period of political deadlock, which arose after legislative elections did not yield a clear majority. The National Assembly is now fragmented, with Macron’s centrist group, a coalition of leftist parties, and the far-right National Rally each wielding considerable influence.

Renowned for his diplomatic skills and as a former negotiator for the European Union on Brexit matters, Barnier is known for his ability to foster consensus. This quality was one of the reasons Macron appointed him, as the President aims to bridge the divides within the government. Barnier’s administration is facing significant challenges, with ambitious goals that include enhancing national security, reforming the educational system, and tackling the escalating debt crisis in France.
