Frank Ibezim, the All Progressives Congress member elected to represent the Imo-North Senatorial District, has been sworn in by Ahmad Lawan, the President of the Senate, on Tuesday.
Ibezim replaced the late Benjamin Uwajumogu who died last year.
The Clerk of the Senate, Ibrahim El-Ladan, administered the oath of office and oath of allegiance.
The APC won the seat but there was no clear candidate.
The Independent National Electoral Commission declared APC as winner but it did not declare any specific person as the occupant of the seat.
The issue lingered between Ifeanyi Ararume and Ibezim before the Supreme Court declare Ibezim as winner.
