As Osun State gears up for its 2026 governorship election, Governor Ademola Adeleke has found himself at the centre of one of the state’s most dramatic political episodes in recent history.
Widely regarded for his grassroots appeal and populist image, Adeleke became the subject of intense speculation in late 2025 over a possible defection from the Peoples Democratic Party (PDP) to the All Progressives Congress (APC). Though the move never materialised, the controversy has left lasting tremors across Osun’s political landscape.
Reports of secret overtures to the presidency first emerged in December 2025, when Adeleke allegedly sought an audience with President Bola Ahmed Tinubu. According to insiders, his defection plan was driven by the desire to secure an automatic ticket for re-election in 2026, while leveraging APC’s federal might against opposition within and outside the PDP.
The governor was said to have lobbied key figures, including Chief of Staff Femi Gbajabiamila, Lagos Governor Babajide Sanwo-Olu, and Ogun Governor Dapo Abiodun. Meanwhile, the PDP scrambled to contain the fallout. At an emergency caucus meeting in Osogbo, Adeleke secured overwhelming backing from state and national party leaders, many of whom pledged to follow him to any platform of his choice.
Yet cracks soon appeared. Several PDP lawmakers, wary of being sidelined by a pro-Adeleke migration, preemptively defected to the APC. This triggered tension within the PDP, while the APC itself split over whether to admit Adeleke. Party leaders such as Senator Iyiola Omisore openly dismissed his advances, warning that Osun APC would not be a dumping ground for political opportunism.
The defection, once planned for July 23, 2025, collapsed after top APC stakeholders rejected Adeleke’s entry. Despite preparations for rallies and branded attire, the governor abruptly cancelled the move, later citing grassroots resistance within the APC. Nevertheless, he publicly endorsed President Tinubu for a second term, signaling ongoing realignment efforts.
The episode has exposed vulnerabilities on both sides. The PDP now faces discontent and defections, while the APC remains wary of internal power struggles. Meanwhile, former governor Rauf Aregbesola’s African Democratic Congress (ADC) is positioning itself as a potential third force, attracting politicians disillusioned by both major parties.
For Adeleke, the failed defection is a political setback but not the end of his ambitions. His next steps could determine whether he consolidates power ahead of 2026—or risks being eclipsed by Osun’s shifting political alliances.
