The protracted absence on medical grounds of Nigeria’s President Muhammadu Buhari has stoked fears of a full-blown political crisis at the heart of Africa’s most populous nation.
The 74-year-old former army general left Abuja for London on January 19, leaving Vice-President Yemi Osinbajo in charge while he took time off.
But on the eve of his return earlier this month, it was announced that he was prolonging his stay to enable him to collect the results of unspecified medical tests.
