President Buhari on Wednesday spoke with former American President, Bill Clinton, on phone, giving the assurance that the coming election will be free, fair and credible.
The president gave the assurance when he received a phone call from Clinton.
According to his media aide, Mr. Femi Adesina, the president also expressed appreciation to Clinton for his continuous support for Nigeria and the growth of her democracy.
He described Clinton as a friend of the country, while commending his constant support for the peace, stability and progress of Nigeria under a democratic dispensation.
President Clinton, who regretted his inability to visit the country to witness the signing of the final peace accord before the general elections, wished Nigeria well as her citizens go to the polls.
Clinton was billed to be present at the peace accord signed on Wednesday.
He however refused to honour the invitation, expressing fear that his presence might be politicized and that that would run counter to the intention of the peace accord.
