No confidence motions have been submitted against the French prime minister, from both sides of the political spectrum.
Far right and left wing parties submitted the motions on Monday (Tuesday AEDT), against Prime Minister Michel Barnier, who was only elected recently, in early September.
French financial assets immediately took a hit, as this development pushed the second-biggest economy in the euro zone deeper into a political crisis.
There is also now serious uncertainty whether the annual budget will be approved.
Barnier's coalition will likely be the first French government to be forced out by a no-confidence vote since 1962.
Multiple parties announced their no-confidence motions after Barnier said earlier on the same day that he would try to push a social security bill through parliament without a vote.
"The French have had enough," National Rally (RN) leader Marine Le Pen told reporters in parliament, "We are proposing a motion of no confidence against the government," she said.
RN lawmakers and the left combined have enough votes to topple Barnier and Le Pen confirmed her party would vote for the left-wing coalition's no-confidence bill on top of the RN's own bill.
"Faced with this umpteenth denial of democracy, we will censure the government," said Mathilde Panot of the left wing France Unbowed party. "We are living in political chaos because of Michel Barnier's government and Emmanuel Macron's presidency."
