The venue is being manned by security operatives, including men of the Nigeria Police Force and Nigeria Security and Civil Defence Corps (NSCDC).
The PDP’s candidate for the election is Eyitayo Jegede.
The party was expected to flag off its campaign last Saturday but, instead, party leaders met in Oyo to strengthen its campaign strategy.
The All Progressives Congress, the party of incumbent Governor Rotimi Akeredolu, who is also seeking re-election, flagged off its campaign on September 5.
Some of the dignitaries already present at the PDP flag-off include the Senator representing Ekiti South, Abiodun Olujimi, and the PDP State Chairman, Fatai Adams.
Representing Vice President Atiku Abubakar at the flag off is Segun Sowunmi.
Other dignitaries are still being expected to arrive at the venue, according to a Channels Television correspondent.
