France has rarely been so central to European politics — and rarely so uncertain about its own direction. The French Republic enters the autumn of 2026 with a minority government navigating a fractured National Assembly, a far right that commands the largest single-party vote share in the country, and a president whose influence over day-to-day governance has narrowed significantly since the 2024 legislative elections produced cohabitation conditions. For the European Union, whose founding architecture was built on a Franco-German engine and whose ambitions still depend on French political will and capacity, the uncertainty in Paris is a structural problem for Brussels.
The domestic picture
Emmanuel Macron’s presidency, entering its final phase before the 2027 presidential election, has been defined by a paradox: strong European ambition combined with chronic domestic political difficulty. The pension reform of 2023 provoked the largest wave of strikes in a generation. The 2024 snap election gamble produced a hung Assembly divided between three irreconcilable blocs — the left-wing Nouveau Front Populaire, Macron’s centrist alliance and the Rassemblement National — none capable of governing comfortably. The current prime minister leads a minority government sustained by ad hoc alliances on specific votes, limiting France’s ability to implement significant domestic reform and, consequently, limiting its capacity to project European ambition credibly.
The dynamics tracked in our analysis of the European far right are visible in their sharpest form in France. Marine Le Pen and the Rassemblement National lead in most presidential polling ahead of 2027. A Le Pen presidency would represent a more fundamental challenge to European integration than her father’s 2002 run — she has dropped explicit EU exit rhetoric, but her commitment to national sovereignty primacy and her scepticism of EU defence integration remain genuine policy positions, not mere rhetoric.
What France brings to Brussels — and what instability costs
France’s EU contributions are specific and significant. Paris has been the primary driver of European strategic autonomy ambitions — the idea that Europe should be capable of acting in its own interest without dependence on American power. France’s nuclear deterrent, its permanent UN Security Council seat, its expeditionary military capacity and its global network of diplomatic relationships give it a distinctive role in European foreign policy that no other member state can replicate. The Franco-German partnership, strained but functional, has historically been the motor of EU integration — providing the political will and the economic weight to move the bloc’s centre of gravity when needed.
When France is domestically distracted, Brussels feels it. The State of the Union address’s thin treatment of enlargement, examined in our Commission priorities analysis, partly reflects a France that is less confident about driving a specific European vision. The coherent European foreign policy that analysts call for depends disproportionately on French engagement. If Paris is absorbed by domestic politics, the EU’s foreign policy ambitions will be correspondingly constrained.
The 2027 horizon
The French presidential election in spring 2027 is, from a Brussels perspective, the most consequential electoral event in the EU’s near future. A centrist or social democratic president would likely restore some Franco-German drive to European integration. A Rassemblement National presidency would test the EU’s cohesion in ways that previous Eurosceptic governments have not. How France resolves its domestic political crisis will, in material ways, determine what kind of European Union emerges from this turbulent decade.
