President Muhammadu Buhari says Vice President Yemi Osinbajo will “coordinate” the nation’s affairs while he is abroad for medical treatment.
A letter sent by the president to the Senate, notifying lawmakers of his trip, however raised questions Tuesday about Mr. Osinbajo’s powers after Mr. Buhari failed to address him as “acting president”.
Mr. Buhari left Nigeria Sunday night, shortly after receiving 82 Chibok girls who regained freedom after three years in Boko Haram captivity.
Since coming to power in May 2015, it is the fourth time Mr. Osinbajo would be acting on behalf of the president.
Mr. Buhari has won praises for promptly handing over power before embarking on each trip.
