Bourne, 61, replaces Jean Castex, whose resignation was expected following the re-election of President Emanuel Macron last month.
Macron and Bourne are expected to form a full government in the coming days.
Bourne is the second woman to hold the post after Edith Cresson, who was prime minister under Socialist President Francois Mitterrand in 1991-1992.
He has served as Labor Minister in Macron’s previous government since 2020. Prior to that, he was Minister of Transport under Macron and then Minister of Environmental Change.
French Prime Minister Jean Castex resigned on Monday in an expected move following the re-election of moderate President Emmanuel Macron last month, who will soon name a replacement.
Costex arrived at the Elysee presidential palace on Monday and formally offered his resignation, which the president “accepted,” Elysee said in a statement.
Macron will announce the name of the new Prime Minister very soon. French media say Labor Minister Elizabeth Bourne is a favorite for the job. In France, it is common for presidents to have more than one prime minister in their term.
Macron and his new prime minister will discuss the appointment of a new government in France in the coming days.
The new prime minister’s first mission will be to ensure that Macron’s moderate party and its allies do well in the French parliamentary elections in June. The vote, scheduled for two rounds, will determine which group has the majority seats in the National Assembly, which is the final word on the Senate in France’s legislative process.
Macron has promised a bill to address rising living costs in France, where food and energy prices are rising. It will prepare its new government and is expected to be presented soon after the parliamentary elections.
If Macron’s party wins a majority in the legislature, the prime minister must ensure that the pension changes promised by the president are enacted into law, including raising the minimum retirement age from 62 to 65. The proposed changes have been criticized by workers, unionists and left-wing voters.
Macron further promised that the new prime minister would be directly responsible for the “green plan”, which seeks to accelerate the implementation of France’s climate policy. Macron has promised to go “twice as fast” in his second term to curb greenhouse gas emissions.
