The Peoples Democratic Party (PDP) presidential candidate, Atiku Abubakar, is currently holding talks with Peter Obi in Abuja.
Mr Obi arrived at Mr Abubakar’s residence in Asokoro neighborhood around 3:00 p.m ., and both have been holding undisclosed talks.
The former Anambra governor is widely speculated as a top candidate for Mr Abubakar to pick as running mate.
The former vice president on Sunday became the presidential candidate of PDP , Nigeria’s main opposition.
Several options have been suggested in the public domain, with the candidate being widely expected to choose from either the Igbo-dominated Southeast or a Yoruba choice in the Southwest part of the country.
It was not immediately clear whether Mr Obi’s visit was in connection to the intensified efforts for a running mate.
