Cameroon's President Paul Biya, the world's oldest leader at 93, is set to appoint a vice-president for the first time in his 43-year rule following controversial constitutional changes approved by parliament on Saturday. This move, which requires the president's signature to become law, reinstates a position that was abolished in 1972. The amendment stipulates that the appointed vice-president will automatically assume the presidency and complete the remainder of the term if Biya is incapacitated or dies, a departure from the previous system where the Senate leader would temporarily take over until new elections. Supporters claim the change enhances government efficiency and representation, while opposition parties criticize it as a power consolidation tactic, with some calling it a "constitutional and institutional coup" and a "missed historic opportunity."
