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.

France's far-right National Rally (RN) party will likely back a no-confidence motion against the government in the coming days unless there is a "last minute miracle", RN president Jordan Bardella said on Monday.

France could see a political earthquake in the coming days as the far right National Rally gave the government a deadline of Monday to agree fresh concessions over the budget.

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 as soon as Wednesday.
