African leaders have raised concerns that their economies will be affected by the exit of the U.K. from the European Union. Experts indicate that the exit of Britain from the EU will force the renegotiation of trade agreements with various countries, in Africa that would amount to about 100 trade agreements. Ghana's President John Mahama told reporters that the continent is now waiting to see the effects of the exit on their economies. Mahama spoke on the sidelines of the AU Summit in Kigali, where he gave a report card on Sustainable Development Goals. Sarah Kimani reports.
