A lack of eligible or worthy candidates means that Hifikepunye Pohamba is only the fourth winner of the USD 5 million annual prize since its launch in 2007.
"President Pohamba's focus in forging national cohesion and reconciliation at a key stage of Namibia's consolidation of democracy and social and economic development impressed the prize committee," said Salim Ahmed Salim, chairman of the Mo Ibrahim Prize committee and a former prime minister of Tanzania, during the announcement of the award in Nairobi.
The award, founded by Sudanese-British telecoms entrepreneur and billionaire Mo Ibrahim, is given to a democratically-elected former head of state who left office in the previous three years and who demonstrated exceptional leadership while abiding by constitutional term limits.
Winners are given USD 5 million over 10 years followed by a further USD 200,000 a year for life, and the aim of the award is to encourage and reward good governance in Africa.
Ex-presidents of Mozambique, Botswana and Cape Verde have been previous recipients of the prize.
