 However, after Aliyu Magatakarda Wamakko, who had been nominated as candidate for the All Nigeria Peoples Party (ANPP), crossed over to the PDP before the election, the PDP ruled that Shagari should run for Deputy Governor in partnership with Wamakko.In April 2008, the Court of Appeal in Kaduna nullified the election of Wamakko and Shagari on the basis of irregularities in the registration process due to the last-minute changes.After a re-run of the election, Wamakko and Shagari were reinstated in May 2008.
