The Supreme Court has ordered the Independent National Electoral Commission (INEC) to replace Ibrahim Shekarau with Rufai Hanga as the Kano NNPP Senator for Kano Central senatorial zone.
In a judgment delivered on Friday by Justice Uwani Abba-Aji, the Supreme Court upheld the judgement of the Court of Appeal, which ordered INEC to recognise Mr Hanga as the candidate.
INEC had declared Shekarau the winner of the February 25 presidential and National Assembly elections.
But the apex court upheld the judgement of the Court of Appeal which recognised Hanga as the Kano candidate.
Shekarau relinquished the Kano NNPP Senate ticket after he defected to the Peoples Democratic Party (PDP).
He had joined the Kano NNPP after he left the All Progressives Congress (APC) as a result of the crisis with the leadership of the party.
Senator Rabiu Kwankwaso, NNPP leader and its Presidential Candidate, had welcomed Shekarau and his supporters to the party, but both men soon fell apart.
Hanga is the pioneer national chairman of the defunct Congress for Progressive Change (CPC).
He chaired one of the parties which collapsed to form the APC in 2014.
Hanga was a key member of the APC before he left the party and an ally of Buhari.
