“No doubt the video is fake,” Ganduje told the BBC Hausa Service on Friday.

“We are making some underground plans, which we will not reveal. But I assure you it is fake, and all those behind it will be put to shame.”

On Friday, Ganduje took his case for self-exculpation to BBC A Fada A Cika programme, aired on Friday evening.

Asked by the interviewer to confirm whether he was the person in the video, Ganduje responded by saying that the video was doctored to show him collecting something.

“Even your picture can be tampered to show something on your head or hand. And you know it’s possible. People always tend to believe falsehood.

“The fact is that we will take action against the matter,” he said.

[“Did he ever take dollar bribe”, asked the interviewer.

Ganduje responded: “It is a lie. Nothing of that nature ever happened.

“It was just part of a scheme to stop me from contesting election – and I contested; to stop me from winning election – and I won.

“But that is not the issue, the big issue that we will deal with those behind it,” he said.
