Cameroon’s president Paul Biya is 92-years-old. He’s been the president for decades. This weekend Cameroonians will vote in presidential elections to decide if he will continue in this role. Despite some criticisms, as well as a host of security and economic challenges, many believe that Paul Biya stands a strong chance of victory.

BBC journalist Paul Njie, who’s based in Cameroon’s capital Yaoundé, joins us to share all we need to know about Cameroon’s upcoming presidential elections - including which issues are important to young voters. And this election has us thinking: how old are other global leaders, and is 90 the new 70 in politics? Jem Westgate from the What in the World team explains.
