Balogun won the seat on the platform of the Peoples Democratic Party (PDP) but recently defected to the APC after he was denied a second term ticket by Governor Seyi Makinde.
The primary which could not hold on Saturday as earlier planned was rescheduled for Sunday due to the inability of the aspirants and party leadership to resolve the discrepancies that arose on delegates list.
The election was eventually held at the Le Chatteau Event Centre, Bodija, Ibadan, on Sunday amid heavy security presence.
Only accredited delegates were allowed into the election venue as journalists were also barred from gaining access into the venue.
Although, there were initial skirmishes between supporters of the aspirants, the intervention of security operatives prevented the matter from degenerating into a full blown crisis.
