French Prime Minister Edouard Philippe has tendered his resignation after heading President Emmanuel Macron’s government for three years.
The president swiftly named centre-right mayor Jean Castex to lead a new team of ministers after a reshuffle.
Although Mr Philippe was considered more popular than the president, the ruling party had poor local election results at the weekend.
President Macron promised a “new path” in an interview published on Friday.
Mr Philippe met the president early in the morning and they agreed the government would resign.
A reshuffle has been expected for some time, and it is common practice for a French president to replace a prime minister during the five-year term in office known as the “quinquennat”.
