The Tamale High Court has annuled the New Patriotic Patriotic (NPP) Walewale Constituency parliamentary primary results.
The court presided over Justice Richard Kogjawah in a ruling on Monday morning ordered a re-run of the primary.
The court held that the election was flawed with irregularities, impersonation and over voting.
In January, Dr Kabiru Mahama, a special advisor to the Vice President, narrowly defeated Hajia Lariba in a tightly contested primary.
The election saw Dr Kabiru winning with 345 votes against Hajia Lariba’s 338 votes. Unsatisfied with the outcome, the incumbent Member of Parliament (MP) on January 27 headed to court to challenge the results, citing electoral irregularities and malpractice.
