The letter sent by the President Muhammadu Buhari to the Senate, notifying lawmakers of his trip to the United Kingdom, where he had gone for a medical follow-up has failed to address vice president Yemi Osinbajo as acting president; instead, the letter addressed him as the 'coordinator of nation's affairs.'

President Muhammadu Buhari says Vice President Yemi Osinbajo will “coordinate” the nation’s affairs while he is abroad for his indefinite medical leave.

It would be recalled that Buhari left Nigeria Sunday night, shortly after receiving 82 Chibok girls who regained freedom after three years in the 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.
