Rwanda Sues Britain After London Scraps £700m Asylum Seeker Plan

(UNITED KINGDOM) — Rwanda has filed formal arbitration proceedings against the United Kingdom at the Permanent Court of Arbitration in The Hague over the scrapped migrant deportation deal, seeking approximately $68.9 million in outstanding payments.

The filing opens a new international legal battle over one of Britain’s most contested recent immigration policies, shifting the dispute from political argument in Westminster to a treaty fight over money, obligations and how the arrangement was brought to an end.

Kigali says Britain still owes substantial sums under the agreement after Prime Minister Keir Starmer’s Labour government dropped the plan in July 2024. The UK has said it will “robustly defend” its position to protect British taxpayers.

The dispute stems from a 2022 migration agreement brokered by former Prime Minister Boris Johnson. Under that arrangement, certain asylum seekers arriving in the UK would have been sent to Rwanda for processing.

At the time, the policy became closely tied to Johnson’s government and to a broader push to deter people from crossing to Britain and then claiming asylum. The asylum seeker plan put Rwanda at the center of a debate over whether Britain could move responsibility for processing some claims outside its own territory.

That approach made the policy politically charged from the start. Supporters cast it as a deterrent, while opponents attacked its legality and cost, leaving the agreement to stand as a test of Britain’s willingness to outsource part of its asylum system.

Starmer’s government ended the scheme in July 2024 after Labour took office. Ministers declared it “dead and buried” and described it as a waste of taxpayers’ money.

That decision ended the policy but not the treaty dispute behind it. Once Britain abandoned the arrangement, attention turned to what had already been paid, what remained due, and whether either side still owed duties under the original terms.

Money now sits at the center of the case. The UK had already paid Rwanda £240 million ($330.9 million) before abandoning the deal.

In November 2024, Britain asked Rwanda to forgo two additional payments of £50 million each that were scheduled for April 2025 and April 2026. The UK argued that request reflected its move toward formally terminating the treaty.

Rwanda indicated it could accept that arrangement if new financial terms were negotiated. Those discussions never took place.

That left the two governments on a collision course. Rwanda filed the case at the Permanent Court of Arbitration in November 2025 after the UK made clear it had no intention of making further payments.

The amount now sought in arbitration, approximately $68.9 million in outstanding payments, gives the dispute a concrete financial focus. It also turns a policy that never operated as intended into a claim about who must bear the cost of its collapse.

Rwanda’s legal case goes beyond the unpaid money alone. Kigali accuses the UK of breaching the treaty in “respect of the financial arrangements”.

It also says Britain breached its commitments by “refusing to make arrangements to resettle vulnerable refugees from Rwanda.” That claim broadens the case from a payment dispute into a challenge over whether Britain carried out promises linked to the wider arrangement.

Kigali further argues that Britain failed to follow the formal steps required to end the agreement. Rwanda says the UK declared the deal “dead and buried” without prior notice.

That argument places the termination procedure itself at issue. In arbitration, Rwanda is not only contesting Britain’s refusal to make more payments but also the way London moved to close down the treaty after the change in government.

The case arrives after a long period in which the policy struggled to survive legal challenges and never reached full operation. The UK Supreme Court ruled in November 2023 that the resettlement arrangement was illegal under international law.

That judgment dealt a severe blow to the scheme before Labour later scrapped it. It reinforced criticism that Britain could not lawfully send asylum seekers to Rwanda under the system then in place.

Operationally, the policy also failed to produce the removals that had formed the heart of the government’s case for it. None of the scheduled flights transporting asylum seekers to Rwanda ever departed.

Only four people voluntarily went to the country. For critics of the plan, that outcome became evidence that Britain had spent heavily on a scheme that did not deliver the removals it was meant to produce.

Those facts now shape the legal and political backdrop to the arbitration. Britain can point to a plan blocked in court and never implemented through the scheduled deportation flights that were meant to define it.

Rwanda, by contrast, is framing the matter as a treaty dispute that survived the policy’s political collapse. From Kigali’s perspective, the fact that the scheme became legally and politically toxic in Britain does not erase obligations that were written into the agreement.

That is why the case turns on more than whether the asylum seeker plan succeeded. It now rests on whether Britain remained bound to honor financial and related commitments even after deciding the arrangement no longer served its interests.

The sums already spent have sharpened that argument. The source content states Britain spent £700m on the scrapped asylum seeker plan, while also stating that the UK had already paid Rwanda £240 million ($330.9 million) before abandoning the deal.

Those figures have fueled the competing narratives around the scheme. Labour used the cost to attack the policy when it came to power, while Rwanda is using the treaty terms to argue that cancellation did not wipe away what Britain still owed.

For Starmer’s government, the arbitration revives a policy Labour sought to close off quickly after taking office. By calling the arrangement “dead and buried,” ministers made clear they wanted to break decisively with the Johnson-era approach to migration.

For Rwanda, the filing keeps the issue alive in a different forum. Instead of contesting whether the policy was wise or workable, Kigali is asking arbitrators in The Hague to decide whether Britain breached the agreement and failed to pay what remained due.

The case also shows how an immigration policy can outlast its political life once it is embedded in a treaty relationship. Britain ended the plan in July 2024, but the legal and financial consequences continued to build through November 2024, when London sought to avoid the later payments, and into November 2025, when Rwanda opened arbitration.

That sequence gives the dispute a clear chronology. First came the 2022 agreement, then the legal challenges, then the November 2023 Supreme Court ruling, then Labour’s cancellation in July 2024, followed by the British request in November 2024 that Rwanda waive the two later payments, and finally the arbitration filing in November 2025.

The UK has signaled that it will fight the claim. Its public position is that it will “robustly defend” the case to protect British taxpayers.

That stance suggests London will cast the dispute not only as a contractual disagreement but also as a question of public spending on a policy it says failed. Rwanda, meanwhile, is likely to keep the focus on the treaty language, the payment schedule and the procedures required to bring the arrangement to an end.

Proceedings at the Permanent Court of Arbitration now move the row into a formal international process that could take time to resolve. The fight over Rwanda and Britain’s abandoned asylum seeker plan has already outlasted the policy itself, and it now turns on whether its final chapter will be written by politicians or by arbitrators in The Hague.
