The French left is facing internal divisions once again, this time sparked by Jean-Luc Mélenchon's call to impeach President Emmanuel Macron. Mélenchon and his allies in the France Unbowed movement are pressuring Macron to appoint Lucie Castets as prime minister, threatening impeachment if he refuses. This has highlighted the fragility of the New Popular Front alliance, which includes Socialists, Greens, and Communists, and undermines the unity they displayed in recent snap elections. While the impeachment threat is unlikely to succeed (it requires a two-thirds majority in both houses of parliament), it has exposed significant fractures within the left-wing coalition. All the other parties, including Castets’ supporters, were quick to distance themselves from the idea. This discord is seen as advantageous for Macron's camp, as it weakens the opposition.
