For years, from one election to the next, French political parties from across the spectrum would unite in the name of democracy to block the far-right National Rally from winning mayoralty races, seats in the National Assembly and – most of all – the French presidency.
By forming a self-described “republican front,” rival parties would temporarily put aside their differences to get behind the candidate with the best chances of defeating the National Rally in any given electoral contest. Indeed, President Emmanuel Macron owed his victories in 2017 and 2022 to voters motivated more by their desire to defeat his National Rally rival than by any wish to put him in the Élysée Palace.
In 2024, rival parties on the left created the New Popular Front to run a single slate of candidates to block the National Rally from winning a majority of National Assembly seats. The strategy worked. But it led to a hung parliament that thrust France into a legislative stalemate.
It also elevated the far-left France Unbowed to a dominant position within the New Popular Front, with 71 seats.
Other leftist and centre-left parties soon came to regret their alliance with France Unbowed and its firebrand leader, Jean-Luc Mélenchon, as they were regularly forced to distance themselves from its radical policies and polarizing discourse.

Any hopes of rebuilding their coalition before next year’s presidential election, much less municipal elections to be held next month, now lie in tatters.
France Unbowed and Mr. Mélenchon now stand accused of condoning political violence after the mid-February beating death of a far-right activist by antifascist militants belonging to a group with links to the party. Calls have emerged across the spectrum to “cordon off” France Unbowed from any future republican front.
The tragic incident at the root of this break-up occurred when antifascist and far-right militants clashed outside a university in Lyon, where a France Unbowed member of the European Parliament known for her strident anti-Israel views was speaking to students. In the melee, 23-year-old Quentin Deranque was pushed to the ground and kicked repeatedly. He later died after suffering a fractured skull and massive brain injuries.
At least 11 people have been arrested in connection with Mr. Deranque’s death, many of them with links to la Jeune Garde (or Young Guard), an antifascist group founded in 2018 by Raphaël Arnault, now a France Unbowed member of the National Assembly. Mr. Arnault is not personally implicated in Mr. Deranque’s killing, but two of his parliamentary aides were arrested in connection with his death, one on murder charges.
Last year, France’s then-interior minister outlawed la Jeune Garde amid a crackdown on far-left and far-right groups accused of promoting violence. Even so, Mr. Mélenchon and other France Unbowed politicians continued to associate with members of the group, some of whom they relied on to provide a security detail at public events. At one 2025 rally, Mr. Mélenchon referred to la Jeune Garde as “my young friends.”
Mr. Deranque’s death has also caused a further chill in U.S.-French relations after the U.S. embassy in Paris retweeted comments from the U.S. State Department’s counterterrorism bureau warning that: “Violent radical leftism is on the rise and its role in Quentin Deranque’s death demonstrates the threat it poses to public safety.”
French prosecutors seek to ban Marine Le Pen from office, jeopardizing presidential bid
The French foreign ministry summoned U.S. Ambassador Charles Kushner to account for what it called foreign interference in domestic affairs. Mr. Kushner, who last year accused France of not doing enough to combat antisemitism, did not show up for the meeting.
The father of U.S. President Donald Trump’s son-in-law, Jared Kushner, Charles Kushner met recently with Marine Le Pen and NR chairman Jordan Bardella. The latter could end up as the National Rally’s 2027 presidential candidate if France’s top court upholds Ms. Le Pen’s 2025 conviction on fraud charges. Mr. Trump’s recent National Security Strategy, which slammed Europe’s immigration and defence policies, said the rise of “patriotic parties” on the continent “gives cause for great optimism.” By all accounts, the National Rally now has Washington squarely on its side.
The political fallout from Mr. Deranque’s death may only be beginning. Increased fragmentation on the left, as Socialist and Green candidates shun electoral alliances with France Unbowed, has not just thrown the outcome of next month’s municipal elections into the air.
Before Mr. Deranque’s death, polls showed that, under either Mr. Bardella or Ms. Le Pen, the National Rally would handily win next year’s presidential vote over any potential candidates from other parties. Now, the prospect of a reconstitution of the “republican front” that blocked a Le Pen victory in 2017 and 2022 looks even more remote.
France Unbowed, not the National Rally, is now the pariah party in French politics.
