Akala made the decision earlier today after meeting the APC National Leader Asiwaju Bola Tinubu in Abuja
The Ogbomoso-born politician will make a statement on his new decision.
His return to the APC will deal a heavy blow on the alliance he was leading among opposition parties against the governing party in the state.
He was leading an alliance between ADP, African Democratic Congress (ADC), Peoples Democratic Party (PDP), Zenith Labour Party (ZLP) and the Social Democratic Party (SDP).
Prior to the election, Akala had vowed that all opposition parties would do anything to end the government of the APC in the state.
But the intervention of Tinubu and other national leaders made him change his mind.
The former governor left the APC last October to pick the governorship ticket of the ADP.
