The announcement was made at noon (12 pm) and the nominee will thereafter be screened by a committee already empanelled for that purpose.
This follows nights of a series of meetings between the candidate and the hierarchy of the party on the issue.
As of Thursday morning the final choice of Atiku remains Ifeanyi Okowa.
“Barring any last-minute change of plans, Mr Okowa would be the nominee to be unveiled this morning,” a reliable campaign insider revealed. Adding, “But as you know even a minute is a long time in politics.”
Paul Ibe, a spokesperson for the Atiku Media Office, declined comment on the identity of the vice-presidential nominee.
Despite reports on Tuesday that the committee overwhelmingly recommended Rivers State Governor Nyesom Wike, his recommendation did not sit well with many leaders of the party.
The leaders felt that Mr Wike is not suitable for a position that places him a heartbeat away from the presidency.
A number of party chieftains raised concerns about the governor’s temperament, his perceived dictatorial tendencies and his propensity for picking fights even with key allies.
Some also argued that Mr Okowa possessed a better intellectual bent and would bring better value to governance at the federal level if the ticket is eventually elected by Nigerians.
Atiku apparently shared their concerns and turned his attention to Mr Okowa who is reportedly his initial favourite for the position.
Mr Okowa supported Atiku in the primary where Mr Wike was his closest challenger.
After his public presentation Thursday morning, Mr Okowa will appear before a screening committee of the party.
Political parties have until Friday (tomorrow) to submit lists of their candidates for the 2023 elections to the Independent National Electoral Commission (INEC).
