Britain will withhold £21 million of aid to Rwanda amid concerns that the state is supporting rebels in the Democratic Republic of Congo (DRC).
International Development Secretary Justine Greening said the money was being withheld due to "creditable and compelling reports" President Paul Kagame had breeched aid agreements.
The Government has already set out its concerns over credible and compelling reports of Rwandan involvement with M23 in DRC. This evidence constitutes a breach of the partnership principles set out in the Memorandum of Understanding and, as a result, I have decided not to release the next payment of budget support to Rwanda.
The UK Government is under international pressure to stop aid to Rwanda amid accusations the funds are being used to arm rebels in the Democratic Republic of Congo, reports the Sunday Telegraph.
The United Nations and European Union want Britain to withhold millions of pounds due to go to President Paul Kagame's government.
Tory Chief Whip Andrew Mitchell ignored Foreign Office advice by giving £8 million in aid to the Rwandan regime shortly before leaving his previous post of International Development Secretary, says the paper.
Mitchell has spent time in the country working on a Conservative "charity" project.
