France has been plunged into deeper political uncertainty following the dramatic resignation of its new Prime Minister, Sebastian Lecornu, a mere 27 days after his appointment. President Emmanuel Macron accepted Lecornu's resignation on Monday, intensifying the nation's ongoing political deadlock that began with snap parliamentary elections in July 2024, which resulted in a fragmented, hung parliament.

Lecornu's short tenure, which made him Macron's fifth prime minister in two years, ended just hours after he announced his new cabinet. This swiftly appointed government faced immediate and fierce criticism from across the political spectrum in the National Assembly. Opponents and allies alike found the cabinet's composition, largely unchanged from that of his predecessor François Bayrou, either too right-wing or insufficiently progressive. This widespread disapproval led to threats of a no-confidence vote, prompting Lecornu to resign before his government could even hold its first meeting.

In a "spontaneous" speech after his resignation, Lecornu appeared to place blame on opposition parties, criticizing their lack of compromise and "partisan appetites." He highlighted that parties continued to behave as if they held an absolute majority, despite the reality of a deeply divided parliament where no single group commands a majority. Lecornu had notably promised not to use Article 49.3 of the constitution, a mechanism previously used to bypass parliamentary votes, arguing this alone represented a significant break from past politics that should have garnered support.

The political instability has been a consistent feature of Macron's second term. His predecessor, François Bayrou, had lasted just nine months, resigning in September after his government was toppled in a confidence vote over his proposals to drastically cut public spending. Bayrou's plan included slashing £35 billion from public spending, freezing pensions and welfare payments, making thousands of civil servants unemployed, and even cutting two public holidays, all aimed at tackling France's national debt, which stands at 114% of GDP.

Lecornu's appointment itself was swiftly followed by major rioting across France, fueled by a "Let's Block Everything" campaign. This movement, aiming to force Macron's resignation, mirrored the decentralized, social-media-driven nature of the Yellow Vest protests and was supported by the CGT trade union. Interior Minister Bruno Retailleau described it as an "insurrectional mood" hijacked by the ultra-Left, with violent clashes reported in cities like Paris and Montpellier.

Lecornu, a former armed forces minister and architect of a major military buildup, was seen by many as a loyal soldier for Macron, not harboring presidential ambitions himself. Despite his background as a former conservative who joined Macron's centrist movement and his experience in managing public anger during various crises, he was unable to bridge the political divides. His cabinet included familiar faces like Gérald Darmanin as justice minister and Rachida Dati as culture minister, with Roland Lescure taking on the crucial economy minister role. Notably, Bruno Le Maire, a long-serving economy minister under Macron, returned to government as defense minister, a move criticized as signalling a continued pro-business stance without significant policy shifts.

The fallout from Lecornu's resignation has amplified concerns about France's financial stability and its ability to manage persistent budget deficits and high public debt. The CAC 40 stock market index fell significantly after the news. The far-right National Rally party, led by Jordan Bardella, has seized on the crisis to demand another snap election, believing they could increase their parliamentary seats and bring greater stability to a currently deadlocked system. With a budget for the next year needing approval within weeks, the nation faces a critical juncture, navigating profound political fragmentation and economic uncertainty.
