The world's oldest head of state - 92-year-old Paul Biya - has promised Cameroon's electorate the best is still to come as he seeks his eighth consecutive presidential term on Sunday.

The nonagenarian has already been in power since 1982 - another seven-year mandate could see him rule for 50 years until he will be almost 100.

He defied widespread calls to step down and has been criticized for only showing up for one rally, spending most of the campaign period on a 10-day private trip to Europe.

A backlash over his reliance on an AI-generated campaign video saw him rush north on his return home, where he addressed crowds of supporters in the vote-rich city of Maroua, particularly reaching out to women and young people, and promising to prioritize their plight in his next mandate.

Political analysts argue that Biya's long tenure has been about maintaining power rather than improving the living conditions for citizens, a sentiment echoed by young activists who feel tired of the status quo.

With political and economic instability fueled by concerns about inflation, security challenges, and escalating unemployment—affecting nearly 40% of youths—Biya faces stiff competition from younger candidates who are appealing to the frustrations of the electorate.

Additionally, in the English-speaking regions of Cameroon, where a separatist conflict has led to significant unrest, the electoral process is further complicated by threats of violence against voters, raising questions about the legitimacy of the upcoming elections.
