Ajayi on Monday morning announced his exit from the party but did not state where he was going next.
Reacting to the development, the PDP said Ajayi's exit had no effect on the party's chances of winning the October 10, 2020 governorship election.
Mr Kennedy Ikantu Peretei, Publicity Secretary of the PDP in Ondo, said Ajayi had abused the privilege accorded him by leaders and supporters of the party during his brief stay.
He said, "He (Ajayi) has proved that he is desperate to become the governor of Ondo State.
"In the days to come, it will dawn on him that he has squandered whatever was remaining of his good will with this decision.
"So, his exit from the PDP will not affect our prospects of winning the October elections.”
