After growing up in a bitterly divided Cameroon, Akere Muna (pictured above in blue cap) trained at the bar in London, and went back to his native country determined to hold the state to account. Resentment is growing towards President Paul Biya’s increasingly repressive regime: 60% of Cameroonians are under 25, and were not even born when the ruler came to power. Muna, who set up the Cameroonian chapter of Transparency International, hopes to effect reforms from within by toppling the 85-year-old leader in the country’s October elections
