Entente Cordiale 2.0: Macron Says Paris Would Back UK Rejoining the EU

French President Emmanuel Macron has indicated that France would support the United Kingdom should London ever decide to apply to rejoin the European Union. Signalling a clear openness toward a potential reversal of Brexit, the French leader offered a friendly tone long absent from cross-Channel diplomacy since the 2016 referendum. While British accession remains purely theoretical with no formal bid on the table from London, the statement removes a major potential diplomatic obstacle in Paris to any future British re-entry attempt.

For citizens and businesses on both sides of the Channel, any eventual UK return would radically alter trade rules, travel restrictions, and residency rights established since Brexit. Rejoining the EU is not a matter of simply restoring the pre-2020 status quo. A returning nation must accept current European legislation, which typically includes commitments to open borders and market integration. Even with political goodwill from key capitals like Paris, the practical consequences would touch everything from passport queues at Dover to regulatory compliance for UK exporters.

In the EU machinery, welcoming back a former member state is less an emotional reunion than an arduous exercise in legal engineering. Under Article 49 of the Treaty on European Union—the legal doorway through which every applicant must pass—any membership request requires unanimous approval from all 27 member states, alongside formal consent from the European Parliament. In Brussels terms, a warm gesture from Paris represents just one of 27 required green lights. The European Commission would then be tasked with conducting a painstaking audit of British law to evaluate regulatory alignment across dozens of policy areas.

With no official re-application submitted by the British government, Macron's declaration remains a political signal rather than an active diplomatic process. Should London ever formally request to rejoin, the Council of the European Union—where national governments sit—would first need to unanimously direct the European Commission to prepare an official opinion. That assessment alone would take months, initiating years of technical negotiations before a final accession treaty could even be drafted.
