Provisional results show Macky Sall has won 65 per cent of the vote in Senegal's presidential election run-off.
Six people were killed and dozens more injured in the weeks leading up to the poll during protests against Senegal President Abdoulaye Wade's changes to the constitution allowing him to stand for a third term.
The family of one victim, Mamadou Diop - a father of two and a human rights activist who had a masters degree in French literature and was working towards a PhD - believes he was deliberately run over by police.
Anta Samb Diop, his wife, says she will not rest until the truth about his death is revealed.
