It expressed its displeasure in a statement issued on Friday, after the candidate of the All Progressives Congress, Gboyega Oyetola, emerged victorious in Thursday’s exercise.
The Independent National Electoral Commission (INEC), declared Oyetola the winner after he got 255,505 votes, while Adeleke secured 255,023 votes.
The group, however, described the election as a sham as Oyetola had trailed the candidate of the Adeleke, by 353 votes going into the supplementary election.
It also alleged that voters were deliberately refused access to polling points at gun points and those allowed to voting centers were forced to vote for the APC.
