French Prime Minister Edouard Philippe has resigned, according to the Elysee Palace.
His departure is expected to pave the way for a government reshuffle.
Mr Philippe will continue to handle government affairs until a new cabinet is named.
Speculation had been growing that a government reshuffle was imminent – with French President Emmanuel Macron seeking to boost his green credentials and win back disillusioned voters.
Mr Philippe had actually seen his popularity increase significantly in recent weeks – despite French authorities facing criticism over their handling of the coronavirus crisis.
Nonetheless, speculation over his future had swirled since mid-June, when Mr Macron declared he wanted to “reinvent” his presidency.
In French government reshuffles, the prime minister tenders his or her resignation ahead of cabinet appointments but can still be renamed to the position.
