Rwanda has taken legal action against the UK at the Netherlands-based Permanent Court of Arbitration. The case involves the UK failing to pay money owed under a cancelled migrant deal. The deal, signed by the previous Conservative government, aimed to send some asylum seekers to Rwanda. In return, the UK agreed to fund Rwanda's hosting costs and support its economy. After Labour came to power in 2024, Prime Minister Sir Keir Starmer ended the deal. The Home Office said £220 million in future payments would not be paid to Rwanda. The Conservatives had spent around £700 million on the policy, which had only brought four volunteers to Rwanda. A government spokesman called the scheme "a complete disaster" that wasted taxpayer cash. Rwanda has not commented directly but their foreign affairs ministry referred to a news article about the arbitration process in a Rwandan newspaper, the New Times. Michael Butera, a government adviser, said, "Through arbitration, Rwanda seeks a legal determination of the parties' respective rights and obligations under the treaty, in accordance with international law." Under the treaty, disputes go to the Permanent Court of Arbitration (PCA) in The Hague. The PCA deals with international disputes and can give binding final rulings. Rwanda started arbitration in November 2024. The PCA has not announced timelines yet. Conservative shadow home secretary Chris Philp criticized Labour, saying this legal fight shows "yet another catastrophic consequence of Labour's decision to scrap the Rwanda scheme before it even started." He warned taxpayers face a big bill. The UK had said it was checking if some money could be recovered, but Rwanda says it owes no refund.
