The lawmaker representing Osun West in the Senate, Lere Oyewumi, has formally defected from the Peoples Democratic Party (PDP) to the Accord Party.
Oyewumi, elected on the PDP platform in the 2023 general elections, was the last PDP senator in Osun State following the earlier defections of Olubiyi Fadeyi and Francis Fadahunsi to the All Progressives Congress (APC).
His defection, announced in a statement obtained in Osogbo on Monday, comes after a series of moves that saw the Osun PDP lose three members of the House of Representatives to the APC in 2025 and 25 members of the Osun State House of Assembly join the Accord Party.
The state governor, Ademola Adeleke, had previously defected to the Accord Party in December 2025.
Oyewumi formally registered as a member of the Accord Party at Ward 9 in Ikire, Irewole Local Government Area.
He was received by party members, the Osun State Chairman, Victor Akande, and other leaders in a ceremony in his hometown.

The statement explained that Oyewumi’s decision followed his earlier resignation from the PDP, citing “irreconcilable differences” within the party and a desire to strengthen his commitment to his constituents.
“Oyewumi’s defection underscores his dedication to effective representation, responsive leadership, and policies that drive meaningful development for his constituents.
Throughout his tenure in the Senate, he has demonstrated commitment, humility, and a deep sense of responsibility toward the welfare of the people of Osun State,” the statement added.
The move is seen as a significant political development in Osun West and aligns with the broader trend of political realignments in the state ahead of future elections.
