Mimiko, who spoke angrily at a press conference, rejected the returning officer INEC deployed for the Ondo polls.
Speaking at a press conference at the State International Event Centre, The Dome, Akure, on Friday, November 25, Mimiko said INEC has put measures in place to ensure the APC candidate, Mr Rotimi Akeredolu (SAN), wins the election.
The Governor, who was said to have spoken angrily, alleged that one of the ploys to rig the election in APC's favour is the deployment of Professor Kayode Soremekun, who was the returning officer for the recent Edo State election, to perform the same function in Ondo State.

Soremekun was accused of rigging the Edo State gubernatorial election in favour of the APC candidate, Mr Godwin Obaseki, who is now the state Governor.
Mimiko said: "We have just been told that the same team of election ad hoc staff, which masterminded the largely controversial Edo election have been sent to our State to deliver a preconceived result for Mr Rotimi Akeredolu, the APC candidate.
"I have to state this here and now, that our people will not accept the method, men and process unleashed on Edo. We reject unequivocally the mission of this team in our State.
"The Edo team did not only call off collation by 9pm on election day, party agents, monitors and journalists were ordered out of the collation centres, allowing for final subversion of the will of the electorate. We shall not allow such an ungodly process to be repeated in our dear State."
The Ondo State election is scheduled to hold on Saturday, November 26.
