Commonwealth heads of government are preparing to defy the United Kingdom and agree plans to examine reparatory justice for the transatlantic slave trade, the BBC has learned. Downing Street insists the issue is not on the agenda for the summit of 56 Commonwealth countries, which begins in the Pacific island nation of Samoa on Friday. But diplomatic sources said officials were negotiating an agreement to conduct further research and begin a “meaningful conversation” about an issue that could potentially leave the UK owing billions of pounds in reparations. The current text of the draft summit communique – made known to the BBC – says: “Heads, noting calls for discussions on reparatory justice with regard to the transatlantic trade in enslaved Africans and chattel enslavement... agreed that the time has come for a meaningful, truthful and respectful conversation toward forging a common future based on equity.” It says the heads of government would play “an active role in bringing about such inclusive conversations addressing these harms” and that they agreed “to prioritise and facilitate further and additional research on the transatlantic trade in enslaved Africans and chattel slavery that encourages and supports the conversations and informs a way forward”. The text – which could still change once Commonwealth leaders arrive – has been hammered out by diplomats ahead of the summit. British officials succeeded in blocking a plan for an entirely separate declaration on the subject. The UK did not want any language in the communique about reparatory justice, but at the moment it is having to accept it will include three full paragraphs setting out the Commonwealth’s detailed position. Reparatory justice for slavery can come in many forms, including financial reparations, debt relief, an official apology, educational programmes, building museums, economic support, and public health assistance. Officials from Caricom, the body that represents Caribbean countries, have sought to broaden the issue so that it encompasses not just the slave trade across the Atlantic but also the Pacific. The draft communique says a majority of member states “share common historical experiences in relation to this abhorrent trade, chattel enslavement, the debilitation and dispossession of indigenous people”. It also refers directly to practices known as “blackbirding”, where Pacific islanders were tricked or kidnapped into slave or cheap labour in colonies throughout the region. Diplomats said the expectation now was that reparatory justice would be a central focus of the agenda for the next Commonwealth summit in two years’ time in the Caribbean, possibly Antigua and Barbuda. In the run up to this year"s summit, there have been growing calls from Commonwealth leaders for the UK to apologise and make reparations worth trillions of pounds for the country’s historic role in the slave trade. A report published last year by the University of West Indies — backed by Patrick Robinson, a judge who sits on the International Court of Justice — concluded the UK owed more than £18tn in reparations for its role in slavery in 14 Caribbean countries. Last weekend the prime minister of the Bahamas, Philip Davis, used a visit by Foreign Office minister Baroness Chapman to tell her the fight for reparations was far from over. According to the Bahamas government website, Davis said: “The call for reparations is not simply about financial compensation. It is not about financial compensation. "It is about recognising the enduring impact of centuries of exploitation and ensuring that the legacy of slavery is addressed with honesty and integrity. "As Caribbean nations, we stand united in our demand for justice for generations who came before us and those of us who are still living with that brutal history.” A UK government spokesperson said they would not comment on the leak to the BBC, but added: “Reparations are not on the agenda for the Commonwealth Heads of Government meeting. The government’s position has not changed – we do not pay reparations. "We are focused on using the summit at [the Commonwealth Heads of Government Meeting] to discuss the shared opportunities which we can unlock across the Commonwealth – including securing more economic growth.” It is understood the Downing Street position – that reparatory justice is not on the agenda – while technically correct, has angered some Caribbean ministers when it was obvious that the issue would be discussed at the summit. It is one of many issues that are not technically on the agenda but will still be addressed and discussed. Sir Keir Starmer landed in Samoa late on Wednesday UK time, becoming the first sitting prime minister to visit a Pacific island nation. Speaking to reporters en route, he said he wanted to discuss current challenges with Commonwealth leaders, especially climate change, rather than issues of the past. “What they"re most interested in is, can we help them working with, for example, international financial institutions on the sorts of packages they need right now in relation to the challenges they"re facing," he said. "That"s where I"m going to put my focus — rather than what will end up being very, very long endless discussions about reparations on the past. “Of course, slavery is abhorrent to everybody; the trade and the practice, there"s no question about that. But I think from my point of view... I"d rather roll up my sleeves and work with them on the current future-facing challenges than spend a lot of time on the past.” King Charles arrived in Samoa for a four-day visit on Wednesday and is due to formally open the summit. On a visit to Kenya last year, the King expressed the "greatest sorrow and regret" over the "wrongdoings" of the colonial era, but stopped short of issuing an apology, which would have required the agreement of ministers. Some non-Caribbean countries are not unsympathetic towards the British position and want the summit to focus more on existing challenges — such as climate change, which is adversely affecting many Commonwealth countries, about half of whom are small island states. But Caribbean countries seem determined to keep pressing the issue. All three candidates hoping to be elected this weekend as the next secretary general of the Commonwealth — Shirley Botchwey of Ghana, Joshua Setipa of Lesotho and Mamadou Tangara of Gambia — have made clear they support reparatory justice. — BBC
