Lere Oyewumi, who represents Osun West in the Nigerian Senate, has officially announced his defection from the Peoples Democratic Party (PDP) to the Accord Party. Previously, Oyewumi was the only senator from the PDP remaining in Osun State after a series of defections, including notable members like Olubiyi Fadeyi and Francis Fadahunsi, who switched their allegiance to the All Progressives Congress (APC). This shift has further marginalized the PDP in the region following the recent trend of its members moving to competing parties.

The political landscape in Osun State has been tumultuous, especially after the state governor, Ademola Adeleke, also defected to the Accord Party back in December 2025. This defection posed questions about Oyewumi's future with the PDP, particularly against the backdrop of increasing instability as several PDP members from the House of Representatives also transitioned to the Accord Party. The recent departure of six representatives has likely added pressure on Oyewumi to make a similar move, resulting in his decision to leave the PDP.

Oyewumi's departure marks a significant shift for the PDP in Osun State, where the party has faced substantial losses in recent months. With the current political dynamics swinging towards the Accord Party and the APC, the PDP's position appears increasingly precarious. Oyewumi's decision could potentially influence other party members, signaling a wider trend of realignment in Nigerian politics as various factions seek to consolidate power ahead of upcoming elections.
