The King says the Commonwealth should acknowledge its “painful” history, as African and Caribbean nations continue to advocate for reparations for the country’s role in the transatlantic slave trade.

“I understand from listening to people across the Commonwealth how the most painful aspects of our past continue to resonate,” the King said in a keynote speech to the Commonwealth Heads of Government Meeting in Samoa on Friday.

“It is vital, therefore, that we understand our history, to guide us towards making the right choices in future.”

Representatives of 56 countries, most with roots in Britain’s empire, are at the meeting.

The demand for Britain to pay reparations or make other amends for transatlantic slavery is long-standing. It has gained worldwide momentum more recently, particularly among the Caribbean Community (CARICOM) and the African Union.

Opponents of reparations payments say countries should not be held responsible for historical wrongs, while those in favour say the legacy of slavery has led to vast and persistent racial inequality today.

On Monday, British Prime Minster Kier Starmer said the country would listen to nations that wanted to discuss the issue at CHOGM, but ruled out apologising for the country’s historic role in the trade.

Bahamas Foreign Minister Frederick Mitchell told the BBC on Thursday the summit’s draft conclusion, expected to be published on Saturday, had paragraphs calling for a discussion on reparations.

Commonwealth leaders are expected to defy Britain and debate at CHOGM ways of securing reparations for historical slavery.

From the 15th to the 19th century, at least 12.5 million Africans were kidnapped and forcibly taken by European ships and merchants and sold into slavery. At its height, Britain was the world’s biggest slave-trading nation.

Those who survived the brutal voyages ended up toiling on plantations in inhumane conditions in the Americas, while others profited from their labour.

“We have demonstrated an unparalleled ability to confound the painful history which brought us together and sit together as equals for 75 years,” Commonwealth Secretary-General Baroness Patricia Scotland, a British diplomat and lawyer who was born in Dominica, told the summit.
