Former Vice-President Atiku Abubakar addressed the press briefly after casting his ballot at his polling unit in Yola North, in north-eastern Adamawa state.
The 76-year-old presidential candidate for the PDP party was shuttled to the front of the queue, where he was quickly verified allowing him to vote.
Afterwards he was mobbed by the press: grown men and women kicking, shoving and elbowing each other for a shot.
He said he was feeling positive and hoped the elections would continue to proceed peacefully.
