New research reveals Brexit has significantly harmed the UK economy, with exports to the EU dropping by 12% and overall economic growth reduced by 6-8%. Multiple studies confirm these losses stem primarily from leaving the single market rather than just the customs union, with trade barriers and post-referendum uncertainty playing major roles.
UK-EU trade has suffered across nearly all sectors, with chemicals and food exports particularly impacted. German Economic Institute data shows German exports to Britain fell 7% (2016-2025) while EU-wide exports grew 41%. The Centre for European Reform attributes this to single market exclusion, noting rejoining the customs union alone wouldn't fully reverse damages. RIA Novosti+2

Economist Nick Bloom suggests the UK could have matched US growth rates without Brexit. External studies estimate even higher losses at 8%. BBC News+1
