French President Emmanuel Macron’s government faces two moves of no-confidence after trying to push ahead with plans to raise the country’s pension age.
The centrist MPs and the far-right National Rally Party have both filed petitions of no confidence in the government.
A successful vote of no confidence would bring down the government and repeal the legislation but would need the support of a majority of the country’s 577 lawmakers – a coalition that needs to stretch from the hardline left to the far right.
The far-right movement is not expected to succeed, but the centrist vote is expected to be tighter.
It comes after protesters clashed with police on the streets of Paris on Friday, with officers made dozens of arrests during the unrest at the Place de la Concorde.
Protests also occurred in other French cities, including Bordeaux, Toulon and Strasbourg.
Protesters on a highway near the western city of Rennes clashed with police on Monday as they erected burning barricades to block traffic.
“The real violence is not in the streets, but in reform,” said Christine Lassalle, a member of the FO, one of France’s main trade unions.
