Keypoints:
- Rwanda seeks over £100 million in compensation
- Dispute stems from a controversial 2022 deportation agreement
- UK rejects claims, citing diplomatic tensions and legal issues
TENSIONS between Britain and Rwanda have escalated as both countries appeared before the Permanent Court of Arbitration (PCA) on Wednesday to settle a financial dispute related to a controversial migrant deportation deal. Rwanda is seeking over £100 million in compensation, claiming the UK has failed to honour payments after the deal was cancelled.
Migrant deal controversy
The agreement, signed in 2022 under then-Prime Minister Boris Johnson, was designed to send migrants arriving illegally in the UK to Rwanda as part of a deterrent strategy. The plan was widely criticised and ultimately never fully implemented, stumbling through legal challenges and political opposition before being scrapped. Only a handful of voluntary relocations ever took place under the scheme.
The UK Supreme Court’s rulings against the legality of the deportation plan were a major setback for its implementation, underlining deep judicial concerns about its compliance with international law.
When Keir Starmer became Prime Minister in 2024, he moved swiftly to abandon the policy, describing it as costly, ineffective and incompatible with international and domestic legal norms.
Rwanda’s claims for payment
Rwanda’s legal team is now asking the PCA to order the UK to pay outstanding sums, including two annual payments of £50m each, which Kigali says remain due under the treaty. It argues that London’s decision to terminate the agreement did not affect its obligation to settle amounts already due.
In addition to the unpaid instalments, Rwanda is seeking a further £6m in compensation, alleging the UK breached a separate reciprocal commitment to host refugees from the Democratic Republic of Congo (DRC), a deal that Kigali says has gone unfulfilled. Rwanda also wants Britain to issue a formal apology for what it describes as an unjust decision to walk away from the agreement.
Britain’s defence and diplomatic tensions
Britain has rejected Rwanda’s claims, arguing that the legal basis of Kigali’s case is weak and pointing to underlying diplomatic tensions. UK lawyers contend that Rwanda’s response is motivated in part by political disagreements, particularly following Britain’s decision last year to suspend most financial aid over allegations that Rwanda backed the M23 rebels in the DRC — allegations Kigali has consistently denied.
London further argues that Rwanda’s sudden reversal on the financial terms of the migration deal came in the immediate wake of the aid suspension, suggesting political motives rather than strictly legal grievance. In its legal submissions, Britain has urged the tribunal to dismiss all of Rwanda’s claims.
Ongoing diplomatic strain
The legal clash has been part of a broader diplomatic rift between the two countries. The abandoned deportation deal — widely covered in Africa Briefing and UK press — had become a flashpoint in debates over Britain’s immigration policy and its international relationships.
For Rwanda, the dispute carries both financial and reputational implications, challenging its role in global migration governance. For Britain, the case underscores enduring domestic tensions around how best to manage irregular migration while respecting legal and humanitarian constraints.
What’s next?
The PCA hearing will continue through the week, with Rwanda presenting its case on Wednesday, the UK responding on Thursday and both sides summarising on Friday. A ruling is expected in the coming months.
The outcome will be closely watched not only for its direct financial implications but also for how it may shape future UK migration strategy and international contractual obligations in an era of heightened scrutiny over offshore asylum arrangements.
