The French president has named Jean Castex, who coordinated France's virus reopening strategy, as the country's new prime minister.
The announcement follows former prime minister Edouard Philippe's resignation on Friday. A government reshuffle is expected in the coming days.
President Emmanuel Macron is seeking to boost the two remaining years of his term with a focus on efforts to relaunch the French economy after the coronavirus crisis.
The reshuffle comes days after a green wave swept over France in local elections.
Mr Macron saw his centrist party being defeated in France’s biggest cities and stumbling across the country.
The reshuffle was planned even before the vote, as Mr Macron’s government faced obstacles and criticism before Sunday’s election as the virus crisis unfolded.
