He said Nigerians had a better alternative by sticking to President Muhammadu Buhari who he claimed had done so much to ensure better future for them.
But Atiku’s spokesman, Paul Ibe, dismissed Nabena’s claims.
Ibe said the forthcoming election would not be about money but the supreme will of Nigerians.
He said, “Nothing can stop an idea whose time has come. Nothing can stop the zeal of Nigerians to elect the president of their choice.
“This election will not be won by money or lies or propaganda or intimidation but by the supreme will of the Nigerian people as expressed in their votes.
“Atiku Abubakar will be elected as president by Nigerians in February 2019 notwithstanding the machinations of the APC-led administration.”
