Clement Ebri, chairman of the primary election panel of the All Progressives Congress (APC) in Lagos, has declared Babajide Sanwo-Olu as winner of the exercise in the state.
Ebri made the declaration at a press conference in Lagos on Wednesday morning.
He had earlier distanced the committee from the election, opposing the open ballot system used.
Ebri said arrangements were in place to commence fresh elections where the secret ballot would be used.
But Tunde Balogun, chairman of the APC in Lagos, disagreed with Ebri, saying the election went on peacefully across the state.
Balogun declared Sanwo-Olu winner of the exercise, announcing that he polled 970,851 votes while Ambode secured 72,901 votes.
At his media briefing on Wednesday, Ebri reeled out the same figures.
