British Prime Minister Andy Burnham arrived at the Commonwealth summit in Antigua with what looked like an olive branch: structured dialogue on slavery, openness to a formal apology, £40m for Caribbean infrastructure over three years, and discussions on debt resets for smaller Commonwealth nations. He explicitly ruled out reparations. The Caribbean reparatory justice movement heard the offer and immediately identified the structural problem: everything Burnham proposed already exists under the UN's Sustainable Development Goals, which every nation signed in 2015. Repackaging standing commitments as reparatory progress is not the same as reparatory justice. Ralph Gonsalves, former prime minister of St Vincent and the Grenadines and a central figure in the Repair Campaign, drew the sharpest line. The CARICOM Reparations Commission's 10-point plan explicitly asks for debt cancellation — not restructuring — and monetary compensation, grounded in the argument that existing Caribbean debts are themselves products of centuries of colonial extraction. Debt relief that leaves the creditor in control of terms is not the same as cancelling debts the movement considers illegitimate in origin. Labour MP Bell Ribeiro-Addy, chair of the Commons' all-party parliamentary group for Afrikan Reparations, framed the core dispute as one of agency. Slavery's defining crime was the erasure of self-determination. If reparatory arrangements are designed and dispensed by the former coloniser without the decisive participation of affected communities, they reproduce the original power asymmetry. "If it is done to us, it is not reparations," she said. "I don't know what it is, but it is not reparative justice." Gonsalves identified the structural fragility of the UK's offer: development assistance is discretionary. It can be expanded, reduced, or withdrawn based on London's priorities, fiscal pressures, or political cycles. Reparatory justice, by contrast, implies an obligation — a recognised debt, not a gift. The distinction matters because discretionary aid keeps the power relationship intact. The giver decides the amount, timing, and conditions. The recipient remains a supplicant. Prof Kingsley Abbott of the Institute of Commonwealth Studies reinforced the point by drawing parallels to his human rights work in Guatemala, Colombia, Nepal, and Myanmar. Across every context, victims of atrocity crimes demanded the same thing: justice and being made whole. The reparations movement positions Caribbean claims within this established international framework of transitional justice, not as a novel or exceptional demand. The Foreign Office response was revealing in its careful avoidance. It spoke of "facing our past together" and "stronger relationships" while listing climate, debt, and development — precisely the areas Gonsalves identified as pre-existing SDG commitments that have nothing to do with reparatory justice per se. The diplomatic language performs engagement while structurally declining the movement's actual demand: acknowledged obligation with agency transferred to the harmed communities. The 56-member Commonwealth summit in Antigua becomes the latest venue for a fight that has been building for decades. The Caribbean is not asking Britain to be generous. It is asking Britain to recognise a debt. Those are fundamentally different requests, and Burnham's offer — however well-intentioned — answers the first while refusing to engage with the second.
