President Muhammadu Buhari is now back home, after his visit to London from New York.
President Buhari went to London at the end of the 72nd session of the UN general assembly, in New York.
Special adviser to the president on media and publicity, Femi Adesina, had said his principal would return to the country on Monday.
But he did not disclose the reason for the UK visit, fuelling the speculation that the trip might be health-related.
