The Governor of Osun State, Ademola Adeleke, has officially resigned from the Peoples Democratic Party (PDP).

His resignation comes less than 24 hours before the PDP’s scheduled governorship primary election.

Adeleke’s decision was communicated in a letter that surfaced on Monday, although it was dated November 4, 2025.

The governor cited ongoing party crises as the reason for his departure. In the letter, he stated:

"Due to the current crisis of the national leadership of the People’s Democratic Party (PDP), I hereby resign my membership of the party with immediate effect. I thank the PDP for the opportunities given to me for my elections as a Senator representing Osun West and as Governor of Osun State under the party."

The PDP Chairman in Osun State, Mr. Sunday Bisi, confirmed on Monday that the party would not proceed with the primary election scheduled for Tuesday due to internal factional disputes. Bisi also revealed that Adeleke is no longer interested in pursuing the party’s nomination because of the crisis.
