You don't need a WAEC certificate to become the president of Nigeria- Festus Keyamo

Lawyer and spokesperson of the 2019 Buhari campaign organization, Festus Keyamo, was a guest on Channels TV last night where the issue of President Buhari's WAEC certificate was discussed. The main opposition party, PDP and other political parties, have contested President Buhari's eligibility to be the President on the grounds that he has not tendered his WAEC results to INEC.
In his interview, Keyamo says a WAEC certificate is not a prerequisite to becoming the President of Nigeria. According to him, if you have occupied public office for a reasonable length of time, by the provisions of the constitution, you do not even need a WAEC certificate to become President of Nigeria.
