Rwanda has formally launched international arbitration proceedings against the United Kingdom, escalating a diplomatic and legal dispute stemming from Prime Minister Keir Starmer’s decision to terminate the controversial UK–Rwanda migration agreement. The case, now registered with the Permanent Court of Arbitration in The Hague, centers on Rwanda’s claim that Britain remains legally obligated to pay £100 million in outstanding treaty installments.
On January 27, 2026, Rwanda’s government confirmed it had submitted a notice of arbitration, arguing that the UK breached binding financial and procedural obligations under the Migration and Economic Development Partnership signed in 2022. The agreement, originally intended to relocate asylum seekers from the UK to Rwanda for processing and resettlement, became politically contentious and was formally abandoned by the Starmer administration shortly after taking office in 2024.
Core Legal Claims
Rwanda’s filing outlines three principal allegations. First, it asserts that the UK failed to honor scheduled financial commitments, specifically two £50 million payments due in April 2025 and April 2026, which Rwanda says remain due under the treaty.
Second, Rwanda accuses the UK of breaching Article 19 of the agreement, which required Britain to resettle a defined number of vulnerable refugees currently living in Rwanda. Kigali argues that the withdrawal halted this process, leaving Rwanda to bear unexpected humanitarian and administrative costs.
Third, Rwanda contends that while Prime Minister Starmer publicly declared the deal “dead and buried” in July 2024, the UK did not complete the agreement’s formal termination procedures. As a result, Rwanda argues the treaty — and its financial obligations — remain valid until its stipulated end date of March 16, 2026.
Rwandan officials describe the UK’s withdrawal as an act carried out in bad faith.
Financial Stakes
Under the agreement, the UK had already transferred £240 million in advance funding to Rwanda before the scheme was canceled. Rwanda is now seeking an additional £100 million in unpaid installments. Had the program continued through 2027, total projected costs were estimated at £700 million.
No asylum seekers were forcibly transferred to Rwanda during the agreement’s lifetime. Only four individuals relocated voluntarily under a separate arrangement, a point cited by the UK government to argue that the policy never became operational.
UK Government Response
The UK government has confirmed it will contest Rwanda’s claims. Officials argue the migration plan was ineffective, costly, and lawfully discontinued, adding that continued payments would impose an unjustifiable burden on taxpayers. They also note that Rwanda already received substantial advance funding exceeding any reasonable compensation.
Arbitration Proceedings
The case has been registered under Case No. 2025-45 and remains pending. A tribunal was constituted on January 1, 2026, with procedural timelines now under way. The ruling may determine whether the UK remains financially liable under an agreement it publicly abandoned but may not have legally terminated in full compliance with its terms.
