Andy BurnhamSpeechOctober 30, 2026

Andy Burnham made the statement in a Guardian article published on 30 October 2026, about calls for a formal apology for Britain's role in the slave trade.

Our verdict

Partly True

Andy Burnham said the UK led the world in abolishing slavery. The UK did pass a law in 1833 that ended slavery in its colonies from 1 August 1834, but we found no evidence to confirm it was the first country in the world to do so.

What we found

The UK Parliament passed the Slavery Abolition Act in August 1833, and it came into force on 1 August 1834, abolishing slavery throughout the British colonies. This is confirmed by The Gazette, the National Archives, legislation.gov.uk and the Irish Statute Book. So the part of the claim about the UK abolishing slavery is accurate. However, the claim that the UK was the first country in the world to do so cannot be confirmed. We found no evidence in our research comparing the UK's abolition date with those of other sovereign states. Because one part of the claim is supported and the other is unproven, we rate the claim partly true.
