Africa Daily - A podcast by BBC World Service

Kenya’s presidential election has been dominating the headlines this week. And while we still don’t know there results, there’s still plenty to talk about. The Kenyan constitution gives all citizens living overseas the right to vote in elections. This year their options have been expanded, with embassies in 12 countries opening their doors for people to cast ballots.

So, is Kenya leading the way on diaspora voting? Or does more need to be done? #AfricaDaily
