Chief Raymond Dokpesi had earlier faulted the electoral, alleging that governors gave the Unity List to delegates before voting started.
One of the National Chairmanship candidates of the Peoples Democratic Party (PDP), Professor Tunde Adeniran, has walked out of the convention ground holding at the Eagles Square, Abuja.
Adeniran rejected the electoral process, describing it as fraudulent and unfair.
Six other candidates from the South-West had pulled out of the race and reached a consensus to support only Adeniran, so that the zone would stand a better chance of emerging winner.
Speaking to newsmen, at the venue, Mr. Taiwo Akeju, the director of publicity to Adeniran, said his boss is against the use of a unity list, which he claims was used to rig the process.
