Obanikoro announced his defection at a press conference in Lagos on Tuesday.
He was received by a former chieftain of the PDP, Lukman Ajose, who recently defected to the APC.
Obanikoro had earlier apologized and reconciled with National leader of the APC, Asiwaju Bola Tinubu.
Obanikoro finally dumps PDP, joins APC
Recall that APC Chairman in Lagos, Henry Ajomale, about a month ago, said Obanikoro would join APC in a matter of weeks.
Ajomale told newsmen in Ikeja that Obanikoro was coming along with other bigwigs of the state’s PDP.
The party chairman said the former Lagos PDP governorship candidate and others had reached out to the party and that all was set for their formal defection.
