The European Union is the United Kingdom's biggest trading partner.

Omissions

• The claim is only true when the EU is treated as a single bloc; on a country-by-country basis the United States is the UK's largest trading partner, accounting for 17.5% (£331.7 billion) of total UK trade in 2025 according to the UK Department for Business and Trade.
• Even as a bloc, the EU accounts for less than half of total UK trade — about 45.7% in 2025, with 54.3% going to non-EU partners — so 'biggest partner' should not be read as 'majority of UK trade'.
• The MEP did not specify a reference year; the figures used here refer to calendar year 2025, the most recent full year available before the session date.
