Atiku resigned from the ruling All Progressives Congress (APC) on Friday.
He was, however, silent on his next political move.
Atiku has reportedly met with Adamawa PDP executives at all levels, as well as state chairmen from the six states that constitute the North-East.
Abdullahi Prambe, state secretary of PDP, said the meetings have been fruitful.
“Our meeting with him has been fruitful and from his body language he will soon return to PDP,” Prambe told reporters.
Prambe described Abubakar’s return as a big boost to the PDP.
“With Atiku, the party will carry more weight and more people will also troop in,” he added
