Mahmood Yakubu, speaking at London's Chatham House think tank, said the Independent National Electoral Commission (INEC) was well prepared to facilitate voting in Africa's most populous nation despite the challenges.
Nigerians are set to choose a new president on Feb. 25, a vote that could have implications across the continent. Current President Muhammadu Buhari is constitutionally term limited after serving two terms.

But Nigeria itself is facing unprecedented insecurity that has seen the INEC itsel.f targeted by violence, including when attackers bombed the headquarters of the electoral commission in Imo state last month.
