Former Lagos governor Bola Ahmed Tinubu has won Nigeria’s presidential election, officials said early Wednesday, marking a victory for the ruling party despite the unpopularity of its outgoing president, Muhammadu Buhari. The opposition, including the campaigns of outsider candidate Peter Obi and former vice president Atiku Abubakar, has vowed to contest the results, saying that a new election should be held under a new elections chief. “Please be assured of our determination to fight the injustice that has been perpetuated on Nigerians through all legal and peaceful means,” the Labour Party’s vice-presidential candidate, Datti Baba-Ahmed, said at a news conference in Abuja on Wednesday.
