2011 Nigerian presidential election

Presidential elections were held in Nigeria on 16 April 2011, postponed from 9 April 2011. The election followed controversy as to whether a northerner or southerner should be allowed to become president given the tradition of rotating the top office between the north and the south after the death of Umaru Yar'Adua, a northerner, when Goodluck Jonathan, another southerner assumed the interim presidency.
