PARIS: Hundreds of thousands of protesters are expected to march through French cities and public workers to strike on Thursday, in a fresh test for President Emmanuel Macron after weeks of unrest that have rattled his government and dominated the agenda five months ahead of a presidential election.

The mobilisation, called by trade unions including the left-wing CGT and backed by student groups, comes after demonstrations over living costs, public services and education triggered the worst civil unrest France has seen in years.

Authorities have sought to lower tensions after riots and looting on October 17 caught security forces off guard, leaving damaged shops and public buildings across the country and fuelling criticism of Macron's handling of the crisis.
