Mali has announced Ibrahim Boubacar Keita as its new leader when the government confirmed the ex-prime minister had won a landslide victory in a presidential poll intended to give a fresh start to the conflict-scarred nation.
Figures for Sunday's second-round ballot announced on live television on Thursday by the interior ministry showed the former prime minister won an overwhelming 77.6 per cent of the vote, with his rival Soumaila Cisse trailing on 22.4 per cent.

Former finance minister Cisse had already conceded the second round run-off to Keita after it became apparent as early as Monday morning that victory was beyond his grasp.
Turnout was recorded at 45.8 per cent, Interior Minister Moussa Sinko Coulibaly said, while just 93,000 ballots were spoiled, compared with 400,000 in the first round.
