French President Emmanuel Macron named a new government on Sunday, putting together a team of largely familiar faces under Prime Minister Sebastien Lecornu as he struggles to pull the country out of a political crisis.

The new cabinet lineup was unveiled nearly a month after the appointment of Lecornu, Macron's seventh prime minister.

The latest premier risks being toppled by the opposition in a deeply divided parliament despite his efforts to obtain cross-party support, and opposition leaders on the right and left were livid on Sunday night.

Bruno Le Maire, who served as economy minister from 2017 to 2024, was named defence minister at a deeply sensitive time of tension with Russia over Ukraine.

Roland Lescure, a Macron loyalist, was named to take over the economy portfolio, with the difficult task of delivering an austerity budget plan for next year.

But many of the other key ministers kept their jobs.

Foreign Minister Jean-Noel Barrot retained his post, the presidency said. Interior Minister Bruno Retailleau, who has vowed to crack down on illegal immigration, and Justice Minister Gerald Darmanin both stayed put.

Rachida Dati, a scandal-ridden culture minister who is set to stand trial for corruption next year, also remained in place.

The presidency unveiled a total of 18 names, with more appointments to be announced at a later stage.

Far-right leader Marine Le Pen said the new cabinet lineup was "pathetic".

Jordan Bardella, the 30-year-old leader of Le Pen's National Rally party, also mocked the government and reiterated the threat of censure.

"We made it clear to the prime minister: it's either a break with the past or a vote of no confidence," he said on X.

Bardella said the cabinet lineup was "decidedly all about continuity and absolutely nothing about breaking with the past".

Le Pen, whose party senses its best chance to come to power, has said she is waiting to hear Lecornu's general policy speech on Tuesday before deciding on any further course of action.

Boris Vallaud, head of Socialist lawmakers, accused Macron's supporters of seeking to plunge France "further into chaos".

"They lose elections but they govern. They don't have a majority but refuse to compromise," he said on X.

The head of the hard-left France Unbowed group, Jean-Luc Melenchon, slammed what he described as a "procession of revenants" mostly hailing from the right, which he said "will not last."

"The countdown to get rid of them has begun," he said on X.

Some opposition leaders have urged Macron to call snap legislative elections or even resign. Macron, who has just 18 months left in power and is enduring his worst-ever popularity levels, has insisted he will serve out his term in full. (AFP)
