In a statement by Patrick Okon, its secretary, the opposition vowed not to “fold our arms” and allow the “day-time robbery”.
The governors urged President Muhammadu Buhari to direct the Independent National Electoral Commission (INEC) to be fair in the election.
“We are aware of the plan of APC to get Ondo state by all means, including enlisting the assistance of INEC,” Okon said in a statement.
“We are warning that we will not fold our arms to watch this impunity and day-time robbery.
“INEC is an umpire and should play its role very well so that the electorate will have confidence in it.
“From the way things are going, the people are already losing confidence in the commission.”
The forum also called on INEC to “stick to its electoral mandate” and should not subvert the law of the land.
“INEC should conduct itself very well in this forthcoming Ondo state governorship election to avoid a repeat of what happened in Edo election,” the statement read.
On Friday, Ayo Fayose, governor of Ekiti state, alleged that the APC had already rigged the election in advance.
He condemned the decision of INEC to clear Jimoh Ibrahim of the Ali Modu Sheriff’s faction over Eyitayo Jegede of Ahmed Makarfi’s group.
