Brexit After a Decade: Economic Impact, Public Regret, and the Debate Over Rejoining the EU

Ten years after the 2016 Brexit referendum, 57% of Britons now view the decision as a mistake, according to a 2023 YouGov survey. Despite this, discussions about rejoining the European Union remain complicated by economic realities, political constraints, and the UK’s unique historical relationship with the bloc.

What Are the Economic Consequences of Brexit?

The Office for Budget Responsibility (OBR) estimates that the UK economy is 4% smaller than it would have been had Britain remained in the EU, with some economists suggesting a 6–8% loss in GDP per capita. The pound has not rebounded to pre-referendum levels, and trade friction has increased, with the EU accounting for 41% of UK exports and 49% of imports in 2023, according to the Office for National Statistics.

Philip Rycroft, the former UK civil servant who oversaw Brexit preparations, recently argued that “Brexit isn’t over” and called for a “sober strategic rethink” of the UK’s relationship with the EU. However, economists warn that a return to EU membership would require accepting stricter alignment with EU rules, higher migration controls, and potential financial obligations, as outlined in a 2023 report by the Centre for European Reform.

Why Is Public Opinion on Brexit Divided?

While 57% of Britons regret the decision, only 36% support rejoining the EU without the “special status” Britain enjoyed during its 43-year membership, such as the opt-out from the Schengen Agreement and budget rebates. This reflects a desire for stability without the perceived costs of full EU integration, according to a 2023 analysis by the British Future think tank.

The emotional weight of Brexit is evident in the “bring back my 2016” nostalgia trend, which saw social media users sharing memories of pre-referendum optimism. However, this sentiment overlooks the complexities of Britain’s historical role in the EU, including its long-standing efforts to negotiate exemptions, as noted in a 2022 study by the London School of Economics.

What Challenges Would a UK Return to the EU Entail?

A new EU membership application would place the UK behind countries like Ukraine and Moldova in the accession queue, according to the European Commission’s 2023 enlargement roadmap. Additionally, the EU has signaled it would not renegotiate the same terms Britain secured in 1973, as reported by Reuters in 2023.

Security and defense obligations also pose hurdles. The UK’s withdrawal from the EU’s Common Security and Defense Policy has left a gap in joint military cooperation, though bilateral agreements under the 2020 EU-UK Trade and Cooperation Agreement aim to mitigate this, according to a 2023 briefing by the International Institute for Strategic Studies.

How Is the Debate Shaping Political Discourse?

Politicians are increasingly cautious about revisiting Brexit, with Prime Minister Rishi Sunak emphasizing “national sovereignty” in a 2023 speech. Meanwhile, Labour leader Keir Starmer has called for a “renewed partnership” with the EU, though his party’s 2023 manifesto stopped short of committing to full rejoining.

The debate mirrors broader European tensions over sovereignty versus integration. As Germany’s Foreign Minister Annalena Baerbock stated in 2023, “The EU must remain a project of equal partners, not a collection of exceptions.”

What Does the Future Hold for UK-EU Relations?

Despite the emotional and economic challenges, experts agree that a full return to the EU is unlikely in the near term. Instead, the UK is expected to focus on bilateral trade deals and sector-specific cooperation, as outlined in the 2023 EU-UK Trade and Cooperation Agreement review. However, as Rycroft noted, “Brexit’s legacy will continue to shape European politics for decades.”
