Mohammed alleged that fraud on the part of either INEC or security operatives cost his party the election. He said Nigerians knew what transpired during the 2019 elections, adding that his party has learnt its lessons.
Governor Bala Mohammed of Bauchi State has said the Peoples Democratic Party won the 2019 presidential election.
President Muhammadu Buhari and former Vice-President Atiku Abubakar were the leading contenders in the election.
While Buhari ran under the All Progressives Congress, Atiku was the PDP candidate.
The Independent National Electoral Commission (INEC) had declared APC the winner of the election.
Although Atiku and his party challenged the election's outcome from the tribunal up to the Supreme Court, they could not upturn the victory of Buhari.
Speaking when he featured on Politics Today, a Channels Television programme, on Thursday, Mohammed alleged that fraud on the part of either INEC or security operatives cost his party the election.
He said Nigerians knew what transpired during the 2019 elections, adding that his party has learnt its lessons.
He said, "The general impression within the party and the country is that we won the election and that we lost to a lot of fraud, to a lot of manipulations that were perpetrated by either the electoral umpire or by the security operatives."
"We do not want to be the whipping boys; we have looked inward to see what prevented us from winning the election. We have a lot of evidence, which we tendered but was not accepted. The issue now is that we know we are all Nigerians. We know the nook and cranny of Nigeria. We know what happened in 2019.
"We are not only looking at the other side and playing the blame game that is the fault of this present administration. We are also critical with ourselves, where we have some gaps, loopholes and inadequacies.
"We are not only looking at the other side, but we are also looking at ourselves, looking at our internal politics, and giving a level playing field for the youths and women who are a majority in terms of demographics and in terms of interest.
"And of course, making sure that the electoral umpire, the INEC that is now instituting some reforms, will also become impartial."
