The payment that had not previously been disclosed was agreed in April this year under a fund for the economic development and growth of Rwanda, the Home Office said in a statement on Thursday. The British government added that it anticipates an additional payment of 50 million pounds next year to Rwanda as part of the same fund. Britain has not paid any more to Rwanda up until now and the payment is entirely separate to the treaty signed on Tuesday to revive a government plan to deport asylum seekers to the East African country.
