The Adamawa Resident Electoral Commissioner, Barrister Hudu Yunusa, has been suspended over the declaration of the election held Saturday.
The Independent National Electoral Commission has invited the REC on Sunday via its official Twitter handle.
Mr Yunusa had earlier declared Senator Aishatu Binani of APC as winner of the supplementary elections.
The commission said the process has clearly not been concluded before he made the announcement.
The statement said, “The attention of the Commission has been drawn to a purported declaration of winner in the Adamawa Governorship election by the Resident Electoral Commissioner (REC) even when the process has clearly not been concluded.
“The action of the REC is a usurpation of the power of the Returning Officer. It is null, void and of no effect. Consequently, the collation of results of the supplementary election is hereby suspended.
“The REC, Returning Officer and all involved are hereby invited to the Commission’s Headquarters in Abuja immediately. Detailed statement to follow shortly.”
