As France’s political centre fractures, the European Union faces the prospect of a presidential race dominated by the far right and the radical left.
France is moving toward the 2027 presidential election with a political landscape more fractured than at any point in the Macron era, raising alarm in Brussels over a possible second-round contest between Jordan Bardella and Jean-Luc Mélenchon.
For European officials, such a scenario would represent one of the most destabilising outcomes imaginable: a face-off between two figures who, from opposite ends of the political spectrum, have built their appeal on rejecting much of the liberal, pro-European consensus that has shaped French policy for decades.
The far-right National Rally, led by Marine Le Pen and fronted increasingly by Bardella, has spent years trying to transform itself from an anti-establishment protest movement into a plausible governing force. Bardella, young, disciplined and media-savvy, has become the party’s most powerful generational asset. His message is simple and effective: France, he argues, has lost control of its borders, its security and its economic destiny.
On the other side stands Mélenchon, the veteran leader of La France Insoumise, whose radical-left movement has fused social anger, anti-capitalist rhetoric and fierce criticism of France’s political establishment. His supporters see him as the only candidate willing to confront inequality, austerity and what they describe as the failures of neoliberal Europe. His critics see him as divisive, confrontational and hostile to the institutional compromises on which the European Union depends.
Between these two poles, France’s centre is struggling to hold.
Emmanuel Macron’s two presidential victories were built on the promise of transcending the old left-right divide. But as his second term nears its end, that political formula looks increasingly exhausted. His allies are no longer united behind a single successor. Gabriel Attal, Édouard Philippe and other centrist or centre-right figures are all competing for the voters Macron once gathered under one banner.
That internal rivalry is precisely what worries Brussels. In France’s two-round presidential system, the first round rewards concentration, not respectability. If the centre and moderate left divide their support among several candidates, Bardella and Mélenchon could advance by commanding disciplined blocs of voters while their rivals cancel each other out.
The result would be a nightmare for the European Union. France is not just another member state. It is a nuclear power, a permanent member of the United Nations Security Council, a founding pillar of the EU and, alongside Germany, one of the engines of European integration. A French president hostile to Brussels, or deeply sceptical of its priorities, would reshape the balance of power across the continent.
A Bardella presidency would likely place immigration, national sovereignty and law-and-order politics at the centre of France’s relationship with the EU. Even if National Rally no longer speaks as openly about leaving the euro or the Union, its instinct remains nationalist, protectionist and suspicious of Brussels’ authority.
A Mélenchon presidency would challenge Europe from a different direction. His programme has traditionally focused on wealth redistribution, public spending, ecological planning and resistance to EU fiscal constraints. That could put Paris on a collision course with European budget rules, NATO strategy and the bloc’s broader geopolitical alignment.
For Brussels, the fear is not only ideological. It is institutional. The EU is already managing war on its eastern frontier, competition with China, uncertainty over the United States, migration pressures and sluggish economic growth. Political instability in France would make every one of those challenges harder.
The coming election is therefore becoming more than a French domestic contest. It is a test of whether Europe’s traditional centre can still organise itself against insurgent forces, or whether voter anger has moved beyond the reach of conventional coalitions.
France’s centrists insist there is still time to avoid the worst-case scenario. But time may also deepen the problem. Every new candidate entering the race risks slicing the moderate vote even thinner. Every public quarrel among Macron’s heirs strengthens the argument that the centre has become a collection of ambitions rather than a governing project.
That leaves Bardella and Mélenchon with a shared advantage: clarity. Each offers a sharply defined alternative to the status quo. Each speaks to voters who believe the system has failed them. And each benefits from the inability of the centre to decide what it wants to become after Macron.
For Brussels, the danger is no longer theoretical. The French election that European officials most feared — a direct confrontation between the far right and the radical left, with the centre reduced to a spectator — is beginning to look possible
