The Nigerian Army has said it is not in possession of the original or photocopies of the credentials of the presidential candidate of the All Progressives Congress, Maj. Gen. Muhammadu Buhari.

It said at a press conference in Abuja on Tuesday that it had a letter from the Principal of Buhari's secondary school, dated 1961, recommending him for enlistment into the military school.

This is an interesting issue here, Buhari has contested for election twice, this is third times.  So if I vote for Goodluck not because of Buhari certificate or all these distractions because Nigerians have better sense than this. Important thing here is who will take Nigeria to next level of life.
