Rwanda is asking Britain for a 50 million-pound payment over a cancelled asylum deal, a source close to the government in Kigali said on Tuesday, after London paused some bilateral aid to the African country over the war in Congo.

The UK government has said it will not send further payments to Rwanda following the cancellation of the migrant deal between the two countries. On Monday, Rwanda's government spokesperson Yolande Makolo said the UK had asked Rwanda to "quietly forgo" the remaining payment - reportedly amounting to £50m ($64m) - based on "trust and good faith".

Rwanda wants Britain to pay it £50 million ($63.5 million) over an abandoned migrant deportation plan, after the UK censured the East African nation for supporting rebels fighting in neighboring Democratic Republic of Congo.

A row has erupted after the UK refused to pay Rwanda more money for the axed migrant deal. Kigali demanded a further £50 million from Britain for the deportation scheme, which was agreed under the Tories but scrapped by Labour.

Rwandan government spokeswoman Yolande Makolo said Rwanda is now "following up" on the £50m to which, she claimed, the UK is legally bound.
