Marine Le Pen, National Rally (RN) leader, has threatened to bring down the French government on Monday if Michel Barnier, France’s prime minister, does not drop effective cuts to pensions.

The French government “has put an end to discussions” on possible changes to the social security bill, Marine Le Pen told AFP on Sunday, paving the way for a possible no-confidence vote on Monday.

To survive the vote in the fractured lower house, Barnier needs Marine Le Pen's party to abstain, otherwise his government and the budget bill could fall, plunging France into a political crisis.
