An independent panel of experts, headed by former Irish president Mary Robinson, has cleared the beleaguered leader of the African Bank of Development (AfDB) of corruption, according to a report obtained by AFP. Akinwumi Adesina, 60, a charismatic speaker known for his elegant suits and bow ties, became the first Nigerian to helm the AfDB in 2015 -- but a 15-page report earlier this year claimed that under his watch the bank had been tarred by poor governance, impunity, personal enrichment and favouritism.
