The Rwandan government has launched legal action against the UK to seek payments it claims it is owed under a scrapped migrant deal between the two countries.

Rwanda has filed a case with the Netherlands-based Permanent Court of Arbitration, arguing the UK has failed to honour commitments made in a deal to send some asylum seekers to the African nation.

Under the deal, which was signed by the previous Conservative government, the UK agreed to make payments to Rwanda to host asylum seekers and support its economy.

But after Prime Minister Sir Keir Starmer axed the deal in 2024, the Home Office said £220m in scheduled future payments will not have to be paid to Rwanda.

A Home Office spokesperson said: The previous government's Rwanda policy wasted vast sums of taxpayer time and money.

We will robustly defend our position to protect British taxpayers.

The Rwandan government has not responded to the BBC's requests for comment. But the country's ministry of foreign affairs pointed us towards an article about the arbitration proceedings in the New Times, a Rwandan newspaper.

The article says the arbitration concerns the performance of specific commitments under the treaty.

The previous Conservative government spent some £700m on the Rwanda policy, which was intended to deter migrants from crossing the English Channel in small boats. Only four volunteers arrived in Rwanda when the deal was in force and Sir Keir said the plan was dead and buried, shortly after Labour won the 2024 general election.

The deal included a break clause, which stated each party may terminate this agreement by giving notice to the other party in writing. The £700m included £290m of payments to Rwanda.

In December 2024, the Home Office stated a further £100m of payments would have been due under the treaty, with projections of £50m each for the 2025-26 and 2026-27 financial years. Additionally, the Home Office agreed to pay £120m upon the transfer of 300 people to Rwanda.

The New Times article quotes a government adviser as saying Rwanda had engaged in diplomatic exchanges before initiating arbitration.

Michael Butera, chief technical adviser to Rwanda's minister of justice, stated: Through arbitration, Rwanda seeks a legal determination of the parties' respective rights and obligations under the treaty, in accordance with international law.

In the treaty signed by Rwanda and the UK, both countries agreed any dispute that could not be settled among themselves would be referred to the Permanent Court of Arbitration (PCA).

The PCA, which is headquartered in The Hague, Netherlands, provides a forum for resolving international disputes between states.

It is a process similar to arbitration that companies regularly agree to as an alternative to potentially damaging and lengthy court battles. The PCA has the authority to issue binding, final rulings if disputes cannot be settled by the countries involved.

Rwanda initiated the arbitration proceedings under the asylum partnership agreement in November, according to the PCA's website, which lists the case's status as pending.

The PCA has not yet indicated how and when the complaint from Rwanda will be handled. Typically, it establishes a timetable for the involved parties to present their arguments, and the cases can take years to resolve.

Conservative shadow home secretary Chris Philp criticized the legal action as a catastrophic consequence of Labour's decision to scrap the Rwanda scheme before it even started, stating that it burdens taxpayers due to the government's indecisiveness.

The UK government previously assessed options to reclaim funds after eliminating the scheme, while the Rwandan authorities maintain they are under no obligation to refund any payments.
