Muhammadu Buhari (Nigeria)
Nigerian President Muhammadu Buhari spent the better part of 2017 holed up in a London hospital treating an undisclosed illness far away from the 180 million Nigerian citizens that elected him to lead them out the worst economic crisis to hit the country in decades.
Mr Buhari’s continued absence fueled a leadership crisis that threatened to boil over on several occasions amid calls for him to take the high road and hand in his resignation if he could no longer cope with the physical and mental rigour of leading Africa’s most populous country.
