The National and state Assembly elections petitions tribunal sitting in Abia state Monday sacked Orji Uzor Kalu as senator representing Abia north.
Kalu is the majority whip of the senate and was elected on the platform of the All Progressive Congress (APC).
People’s Democratic Party (PDP) candidate Mao Ohuabunwa had challenged Kalu’s victory at the tribunal.
The tribunal ordered the Independent National Electoral Commission to conduct a supplementary election within 90 days in eight wards in Arochukwu Local Government Area and several polling units in Ohafia and Isukwuato LGAs where votes were cancelled during the poll.
