While Le Pen and her faction gave Barnier's government benefit of the doubt support following July's snap legislative elections, in which the National Assembly was left in a three-way split between the leftist NFP, the National Rally, and neo-liberal Macronists, Prime Minister Barnier's move on Monday to invoke a constitutional loophole in an attempt to push through effective cuts to social security payments to seniors without a vote in the parliament, saw Le Pen revoke her support from the government and announce her support for the NFP's no confidence vote.

The motion passed the National Assembly on Wednesday as 331 MPs voted in favour of collapsing the government, far surpassing the 289 needed to pass. It marks the first time since 1962 that a government in Paris was ousted by parliamentary vote. Having only served 91 days in the post, former Eurocrat and top Brexit villain Barnier now owns the title for the least time spent as prime minister, behind Pierre Bérégovoy at 362 days, Maurice Couve de Murville at 345 days, Edith Cresson at 322 days, former Macron PM Gabriel Attal whose reign ended at 240 days earlier this year, and Bernard Cazeneuve at 161 days.

In his final speech in front of the National Assembly on Wednesday ahead of his fait accompli removal, Barnier said: "This is reality. I tried to confront it by presenting difficult financial texts. I would have preferred to distribute money, even if we don't have any. But this reality remains there, it will not disappear by the magic of a motion of censure. This reality will be remembered by any government whatever it may be."
