French President Emmanuel Macron will address the nation on Thursday night, a day after Prime Minister Michel Barnier was ousted in a no-confidence vote.
The presidency said on Thursday that Barnier had resigned his post, but would remain in office on a caretaker basis with his ministers until a new government was appointed.
Names for a new prime minister have been swirling, including Defence Minister Sébastien Lecornu, Interior Minister Bruno Retailleau and centrist former presidential candidate François Bayrou.
But finding a name that would not immediately be shot down by one of the large parliamentary factions could take some time, as it did in the summer, when former PM Gabriel Attal stayed on as caretaker for two months.
