Over the weekend, Mélenchon and his allies urged Macron to appoint Lucie Casta as prime minister once again. However, they stated that if Macron does not concede to their demands, Parliament should initiate a vote of no confidence, arguing that “refusing to acknowledge the parliamentary elections and deciding to ignore them constitutes a reprehensible violation of the fundamental requirements of the presidential mandate,” as Mélenchon wrote in an article published in La Tribune. The article was co-signed by prominent party members.

The motion of no confidence would need to be approved by two-thirds of the members in both houses of the French Parliament, making it highly unlikely to succeed.

Politico notes that this new conflict within the New Popular Union (Unbowed France, Greens, and Socialists), which came first in the snap elections, is a positive development for Macron’s camp, which hopes to benefit from a fragmented opposition.

Other parties within the coalition quickly rejected Mélenchon’s call, and even Casta’s camp distanced itself from the no-confidence threat, telling Politico that it was “an initiative of Unbowed France” rather than Casta herself.

Despite their joint candidacy in the parliamentary elections and the shared proposal for Casta, the parties within the coalition still have disagreements.

New talks with President Macron about the prime ministerial appointment are set to begin this Friday. A Socialist official openly stated that if Mélenchon’s party does not withdraw its proposal, “we cannot go to the Élysée to meet a president whose removal we are demanding.”
