Michel Barnier, the EU’s former chief Brexit negotiator, has been named France’s new prime minister, the French president’s office says, ending two months of stalemate following inconclusive parliamentary elections.

In a statement on Thursday, the Élysée Palace said: “The President of the Republic has appointed Michel Barnier as Prime Minister. He has to form a united government to serve the country and the French people.”

The statement added that Barnier’s appointment comes after “an unprecedented cycle of consultations” in order to ensure a stable government.

Barnier, 73, a staunch Europhile, is a member of the Republicans party which represents the traditional right. He is best known on the international stage for his role in mediating the United Kingdom’s exit from the European Union.

A 40-year veteran of French and European politics, Barnier has held various ministerial positions in France, including roles as foreign, agriculture and environment ministers. He served twice as a European commissioner as well as an adviser to President of the European Commission Ursula von der Leyen. In 2021, Barnier announced his bid for presidential elections but failed to garner enough support within his party.

Macron accepted the resignation of former Prime Minister Gabriel Attal and his government in July, after his centrist Ensemble alliance was defeated in the second round of France’s snap parliamentary election. The president has since faced calls from across the political divide to name a new PM. Last week, Macron told journalists during a trip to Serbia he was “making all the necessary efforts” to finalize a name.

Barnier’s prospects for forming a stable government are unclear. Currently, France’s far-right National Rally (RN) is one of the largest parties in parliament following the election in early July. It has previously suggested it could be open to working with Barnier and would not immediately veto him.

Still, RN politician Laurent Jacobelli spoke disparagingly of Barnier, telling French television network TF1: “They are taking out of mothballs those who have governed France for 40 years.”

Barnier served as the chief negotiator during the UK’s exit from the European Union. The lengthy talks between London and Brussels ran from 2016 to 2021 and he is known among Brexiteers in the UK for driving a hard bargain.

Born in January 1951 in a suburb of the Alpine city of Grenoble, Barnier was first elected to parliament at the age of 27.
