What Is Wrong With This Photo Of Buhari, Osinbajo, Oyegun & Others? Who Is REALLY President?

By hierarchy of status or authority, the most important person should always be positioned CENTER in a group photograph. So, why is President Buhari sitting on the left while APC Chairman Oyegun is in the middle and Vice President Osinbajo is STANDING at the back?

Who is really President in Nigeria???
