A referral concerning LFI's European parliamentary assistants led to a lengthy investigation. OLAF identified breaches and irregularities in the work of two former assistants and estimated the loss to the European Parliament at slightly more than €500,000. Two former assistants were granted assisted witness (témoin assisté) status.

At a rally in Lyon, Mélenchon made an ironic remark about the pronunciation of Jeffrey Epstein's name, linking its pronunciation to his origins. Days later in Perpignan, he distorted Raphaël Glucksmann's name. The LDH, Glucksmann and numerous left-wing politicians denounced antisemitic or conspiratorial codes.

Several French-Israeli victims of the 7 October 2023 attacks filed a complaint against Mélenchon and LFI for glorification of terrorism following remarks made on 25 June 2026. The complainants considered that his wording tended to recharacterise the acts of 7 October as acts of resistance. The complaint was referred to the Paris prosecutor's national unit for combating online hatred.

In preparing for the 2027 presidential election, Mélenchon increasingly favours influencers and digital media sympathetic to his movement, says "I choose where I go" and excludes certain media outlets from "officialdom". At the same time, he calls journalists "old fossils", "old fogeys", "devious", "slimy" and "liars", describing the press as a "caste".

Mélenchon proposes freezing or cancelling the portion of French debt held through Banque de France and the Eurosystem, going so far as to say that the bonds could simply be taken and "thrown into the fire". The proposal becomes a major controversy in the presidential campaign. Economists, Christine Lagarde, the Bundesbank president and, on 11 September 2026, Banque de France Governor Emmanuel Moulin consider it contrary to the treaties or dangerous to financial credibility.

Mélenchon announces his fourth presidential candidacy, following 2012, 2017 and 2022. The decision revives criticism of LFI's personalisation and internal succession, with Le Monde recalling that after 2022 he had suggested that a successor should be prepared.

The new LFI leadership established in late 2022 sidelined several longstanding figures critical of Mélenchon. In 2023, Raquel Garrido was barred for four months from speaking on behalf of the group after publicly criticising the founder; activists also denounced the lack of pluralism and democratic bodies. In 2025, the investigation La Meute, based on more than 200 testimonies according to its authors, described a system demanding total loyalty to Mélenchon.

Following Marine Le Pen's conviction and a disqualification from office subject to provisional enforcement, Mélenchon argued that removing elected representatives should be a matter for the people and criticised immediate disqualification before appeals had been exhausted.

A Le Monde investigation documented longstanding financial links between Mélenchon's political organisations and Mediascop/Sophia Chikirou. In 2016, Mélenchon reportedly personally requested that the association Politique à gauche advance €8,400 to Mediascop, still unpaid six years later according to the documents examined. The same case examined Mediascop's 2017 margins and other transfers. Chikirou was formally placed under investigation in 2024 in the 2017 campaign investigation.

Following the massacres of 7 October 2023, Mélenchon and LFI's leadership refused for several weeks to use the political description "terrorist group" for Hamas, preferring classifications they considered grounded in international law. This position caused a major rift with the PS, Greens and communists and contributed to Nupes breaking apart.
