Botswana's former President Festus Mogae has won a $5m (£2.8m) prize to encourage good governance in Africa. He stepped down in April after serving two terms in office. Botswana is one of Africa's most stable countries - it has never had a coup and has had regular multi-party elections since independence in 1966.
Announcing the prize, ex-UN Secretary General Kofi Annnan also commended Mr Mogae for his action to tackle the Aids pandemic which has ravaged the country.
The Ibrahim Prize - the most valuable individual annual prize in the world - was set up by Sudan-born telecoms entrepreneur Mo Ibrahim. As well as the $5m prize, Mr Mogae, 69, gets $200,000 a year for the rest of his life
