The name of Saraki was among the list of candidates submitted to the commission in Abuja on Thursday night.
Saraki, who represents Kwara Central District in the Senate, was among the 13 presidential aspirants of the party.
He came third at the party’s national convention which was held in Port Harcourt, Rivers State.
The Punch reports that the PDP had held the senatorial primaries before that of the presidential primary.
While Saraki paid for the PDP nomination and expression of interest forms, it was however not clear if he paid for that of the Senate as well.
Investigations by The Punch in Abuja showed that Saraki’s name was used to replace the name of one Ope, whose name was initially filed as the PDP candidate for the senatorial district.
It had initially been speculated that the former governor of Kwara State was among the suspected presidential aspirants in the party who had another plan since they knew they could lose the PDP presidential nomination.
It was learnt that Saraki is being positioned to return as the President of the Senate in 2019 by the PDP, if former Vice President Atiku Abubakar wins the presidential election.
The source said, “Bukola Saraki’s name is there (in the list). He’s returning to the Senate on the platform of the PDP.”
