Muhammadu Buhari, Nigeria
Nigeria’s current president claims that his WAEC certificate (high school diploma) is in the custody of the Nigerian Army where he submitted them at the point of enlistment in the military. The former Major General of the Nigerian Army has been accused by citizens and some members of the opposition, demanding the Independent National Electoral Commission (INEC) out-rightly exclude Buhari from the race on account of his inability to provide the WAEC certificate.
This is also a constitutional demand that requires contestants for the office of president to be secondary school graduates at the very least. Mr. Buhari, as Nigerians well know, has not been able to produce this evidence.
