Counting has begun in the wake of Saturday's Nigerian elections. The ballot of 90 million registered voters has been described as broadly smooth and peaceful, despite reports of isolated violence, delays and technical hitches. The electoral authorities have given no date for the announcement of results, but the outcome must be declared within 14 days.
The election pits former Lagos governor and APC candidate Bola Tinubu, 70, against former vice president and PDP candidate Atiku Abubakar, who at 76 is on his sixth bid for the nation's top job.
