The candidates of the main opposition Peoples Democratic Party (PDP), the All Progressives Grand Alliance (APGA), and the Labour Party (LP) in Ebonyi state, have called on the Independent National Electoral Commission (INEC), to cancel the ongoing Abakaliki North Constituency Supplementary election. They accused some officials of the Nigeria's electoral umpire of colluding with the ruling All Progressives Congress and security agents to rig the poll.
