By Efio-Ita Nyok | 31 March 2015| 6:00 pm Mohammadu Buhari, the presidential candidate of Nigeria's leading opposition party, the All Progressives Congress(APC) has emerged the winner of the 28 March 2015 presidential elections with an overall result of 15,306,629 as against the incumbent president Goodluck Jonathan's 12,719,963. Though the Independent National Electoral Commission (INEC) is yet to officially announce the final results, it is obvious the opposition party has won. The election was perceived to be based on a handful of realities, prominent among which were religious and ethnic sentiments, it has been also alleged that the ruling PDP was also voted out of power on the bases of his inability to address the security and corruption challenges that bedevilled the country under his watch. As at press time, the incumbent president, Goodluck Jonathan, is said to have called on the winner of the 2015 presidential election, President-elect Muhammadu Buhari, to concede defeat and congratulate him. This is the first time an incumbent president of Nigeria is unseated by the opposition. This is a rare demonstration of believe in Nigeria's democratic process by the incumbent president.
