On the eve of the Pope's funeral, the question of who will replace the Pope is already on everyone's lips. Can it be an African? Of the 135 cardinal electors, 18 are from Africa. That's a growing significance as the continent accounts for around 20% of the world's Catholic population. Some names have been mentioned, such as Peter Turkson from Ghana, a progressive voice, or the conservatives Robert Sarah from Guinea and Fridolin Ambongo Besungu from DR Congo.
