The presidential candidate of both the Peoples Democratic Party, and his Labour Party have refused to concede defeat in the February 25 presidential election, vowing to recover their mandate in court.
The two candidates refuse the gesture of conciliation made by the President-elect, Bola Tinubu, who in his acceptance speech after he was declared the winner of the poll on Wednesday, asked them to support him in the task of building the nation.
Atiku and Obi spoke at separate news conferences in Abuja on Thursday.
In the early hours of Wednesday, the Independent National Electoral Commission declared Tinubu as the President-elect after the 70-year-old polled 8,794,726 votes to defeat his closest rivals, Atiku and Obi who scored 6,984,520 and 6,101, votes, respectively.
Breaking his silence 24 hours after Tinubu was declared the winner of the hotly contested polls, an emotional Obi insisted that he won the election and he was ready to prove it.
He noted that the election in which Tinubu was declared victorious was controversial and programmed to deliver pre-determined results.
He pointed out that the election did not meet the requirements and could not be deemed credible.
