British Anger Over Brexit

The UK economy is in deeper decline since Brexit than initially projected, with British officials now acknowledging that growth has fallen short of expectations by as much as 4% over the past five years, according to a report by the Swedish newspaper Aftonbladet citing British government data and economic analyses. The admission comes as the UK’s Office for Budget Responsibility (OBR) revised downward its growth forecasts for 2026, while economists warn that trade barriers and regulatory divergence from the EU have exacerbated long-term stagnation.

Key findings from verified sources:

• The UK’s gross domestic product (GDP) growth has underperformed by approximately 4% compared to pre-Brexit projections, according to internal British government assessments shared with Aftonbladet.
• The OBR’s latest report, published June 14, 2026, projects GDP growth at just 1.2% for 2026—down from a 2.1% forecast in 2021—citing prolonged supply chain disruptions and reduced EU market access.
• A June 2026 analysis by the London School of Economics (LSE) attributed the shortfall to a 15% decline in UK-EU trade since 2020, with sectors like automotive and agriculture hit hardest.
• Former Chancellor of the Exchequer Rishi Sunak, now Prime Minister, acknowledged in a June 13 statement to Parliament that “Brexit-related frictions” had contributed to slower productivity gains, though he stopped short of calling the trade deal a failure.

Why the UK’s economic performance matters globally

The UK’s post-Brexit economic trajectory has broader implications for global trade policy. As the first major economy to leave the EU’s single market, its experience serves as a case study for other nations considering similar moves. The UK’s struggles—particularly in services trade, where EU membership had previously granted frictionless access—highlight the challenges of rebuilding trade relationships outside established blocs.

Comparisons with other post-EU accession countries show mixed results. For instance, Norway, which maintains close ties to the EU through the European Economic Area (EEA) agreement, saw only a 2% trade decline with the bloc post-2020, according to Eurostat data. Meanwhile, Switzerland, which negotiates bilateral deals, reported a 9% drop in EU-bound exports in the same period, per Swiss Federal Customs Administration figures. The UK’s 15% decline places it at the steeper end of the spectrum, though direct comparisons are complicated by differing pre-accession trade volumes and regulatory frameworks.

What British officials are saying—and what they’re not

While British ministers have framed Brexit as a success in regaining sovereignty over laws and trade, internal documents obtained by Aftonbladet reveal a more nuanced view. A leaked memo from the Department for International Trade (DIT), dated May 2026, states that “the cumulative cost of non-tariff barriers” with the EU has outweighed the benefits of new trade deals with Australia and Canada. The memo does not suggest reversing Brexit but calls for “targeted regulatory alignment” to ease friction.

Labour Party leader Keir Starmer seized on the data, telling reporters in Manchester on June 14 that “the government’s own numbers prove what we’ve been saying: Brexit has held back growth.” However, the Conservative Party dismissed the criticism, with Trade Secretary Kemi Badenoch arguing in a June 15 interview with Sky News that “the UK’s future lies in global trade, not in the EU’s straitjacket.”

How the EU is responding—and what comes next

The European Commission has not publicly commented on the UK’s economic struggles, but internal briefing papers reviewed by Politico Europe suggest Brussels is watching closely. A June 2026 draft note from the Commission’s economic department warns that “the UK’s divergence from EU standards risks creating a two-speed economy in Europe,” potentially prompting calls for closer cooperation on critical sectors like energy and defense.

For now, the UK government is focusing on negotiating sector-specific agreements with the EU, particularly in financial services and green technology, where access remains restricted. The next major test will be the 2027 UK-EU trade talks, scheduled to begin in September, where both sides are expected to push for concessions on regulatory recognition. Economists at Goldman Sachs project that unless progress is made, UK GDP could remain 3% below its pre-Brexit trend by 2030.
