He submitted the form two days after himself, Obafemi Hamzat and Jide Sanwoolu, two prominent APC chieftains in Lagos, picked up governorship forms at the APC secretariat.
NaijaNews had reported that there may be ongoing plans to impeach Ambode if he does not drop his second term bid.
At a meeting held after he picked up his nomination form, James Odunmbaku, an ally of Tinubu known as “Baba Eto” in the political circle, said “Sanwololu is the incoming governor of Lagos.”
Both Ambode and Tinubu have said nothing on the reports of the rift between them.
Sanwoolu and Hamzat have also submitted their forms.
