The party also restated its position on its withdrawal from the council polls.
Mr. Mimiko, once the leader of the party in the state, dumped it for the Peoples Democratic Party, shortly before the 2015 general elections.
The Secretary of the party, Ronke Akerele, in a statement on Tuesday in Akure, said there was a plan by the governor to keep a fifth columnists as fake members of the party to further his selfish interest.
“We hereby state clearly that anyone who is not known to our party cannot speak or represent our party in any capacity,” she said.
“We also wish to inform the general public that Labour Party shall not participate in the waddle council election.
“The party appeals to the governor to channel his energy to the task of governing the state at this critical period.”
Ms. Akerele said LP would engage the government in constructive criticism for the benefit of all, rather than petty issues of divisive politics that was fast becoming the trademark of the governor.
“We passionately appeal to the Governor to pay the salary arrears of the workers of Ondo State as soon as possible to reduce the untold hardship of the people,” she added.
