Liberia’s ex-president, Ellen Johnson Sirleaf, has won the $5m (£3.6m) Ibrahim prize for African Leadership.
Mrs Sirleaf, who stepped down last month, became Africa’s first elected female president in 2006.
She was praised for her work rebuilding the nation after civil war and leading a process of reconciliation.
The prize committee admitted that while Mrs Sirleaf was accused of tolerating corruption, she had shown exceptional leadership in difficult circumstances.
It added that Liberia was the only country out of 54 to improve in every category and sub-category of the Ibrahim Index of African Governance.
Mrs Sirleaf served two terms as president, but could not run again in recent polls, which were won by former footballer George Weah.
Her own party has expelled her, alleging she had campaigned for Mr Weah rather than her party’s candidate.
She is the fifth recipient of the prize since 2007, which celebrates African leaders who governed well, raised living standards and then left office.
The $5m prize is spread over 10 years and is followed by $200,000 a year for life.
But it is not always awarded. On six occasions, no leader was considered worthy of it.
