Cameroon's President Paul Biya, at 92 the world's oldest head of state, is seeking re-election in October. His enduring power is attributed to a system maintained through repression and the fear of losing access to benefits. Critics argue this creates a climate of authoritarianism, suppressing dissent and limiting political freedoms. The upcoming election is expected to be closely contested, given growing calls for political change and a more democratic system in the country.
