The President-elect, Bola Tinubu, extending an olive branch to his opponents, Atiku Abubakar of the Peoples Democratic Party and his Labour Party counterpart, Peter Obi, after the contentious presidential election in which he was declared the winner on Wednesday.
Tinubu said political competition must now give way to conciliation and inclusive governance.
The Independent National Electoral Commission declared the former senator the winner of the election after he polled 8,794,726 votes.
The INEC Chairman, Prof. Mahmood Yakubu, announced Tinubu as the winner at the International Collation Centre in Abuja during the early hours of Wednesday.
But the PDP, LP and the New Nigeria Peoples Party agents walked out of the hall and refused to sign the election results sheet of the presidential election.
They rejected the declaration of Tinubu as president-elect after accusing the INEC of compromise, insisting that the election should be cancelled, and a fresh poll conducted.
The commission later presented the certificates of return to Tinubu and the vice president-elect, Kashim Shettima around 4pm.
