The committee promised to conduct a free, fair and transparent primary in accordance with the party's constitution and guidelines.
The election committee for Osun All Progressives' Congress (APC) governorship primary, on Thursday met with all the 17 aspirants, and called for calm.
Sen. Ovie Omo-Agege, chairman of the committee, who addressed the aspirants at the party's Secretariat in Osogbo, urged them to eschew violence and bitterness during the exercise.
Omo-Agege, representing Delta Central at the Senate, promised that the committee would conduct a free, fair and transparent primary in accordance with the party's constitution and guidelines.
"We are neutral in this election and we are not here to impose any aspirant on you. We will give you a credible election that all of you will be proud of. We will be fair to all," he said.
The senator, who later read out the guidelines for the primary, said that anyone that would participate in the election must be a registered member of the party.
He said that each member would also be accredited with a valid voters card or party membership card before he could vote.

He said that a 5-man committee was constituted in all the local governments and a 3-man committee at the ward levels.
The senator added that Gov. Abdul'aziz Yari of Zamfara would be the chairman of the committee.
According to him, direct method of voting would be used to conduct the primary in line with the directive of the National Working Committee (NWC).
Some of the aspirants in their reactions alleged that the primary had been schemed in favour of a particular aspirant.
They also alleged that few hours to the primary they were yet to receive the party's register that would be used.
