The Peoples Democratic Party and the Labour Party have asked the Independent National Electoral Commission (INEC) to suspend the ongoing collation of results for Saturday’s presidential election.
The leadership of both parties issued the advice to the electoral body in separate media briefings in Abuja on Monday.
The Director General of the LP presidential campaign council, Akin Osuntokun, said INEC and President Muhammadu Buhari have failed to deliver on their promise of free and fair elections.
The LP campaign DG said the party has received reports of electoral malpractices across the country and accuses INEC of not sticking to its guidelines.
Osuntokun urged INEC to carry out a comprehensive review of the exercise before deciding on whether or not to continue collation.
In addition, the PDP Publicity Secretary, Debo Ologuagba, accused INEC of rigging the elections in favour of the ruling All Progressives Party (APC).
The PDP also accused the electoral umpire of violation of the electoral act by failing to transmit the results to the INEC server.
The party said the integrity of the exercise had been compromised.
The PDP alleged that INEC deliberately delayed the commencement of collation and rejected the ongoing collation process.
