President Muhammadu Buhari has officially resumed duties on Monday and has met with Vice President Yemi Osinbajo who had been acting on his behalf while he was away on medical vacation in London.

The President also signed a letter to the National Assembly informing it of his return as well as assumption of office.

Senior Special Assistant to the President on Senate matters, Ita Enang, was sighted by state house correspondents with a copy of the letter but he refused to comment on the details.

But President Buhari’s spokesman, Femi Adesina confirmed the development via his tweeter handle, saying: “PMB has signed a letter informing the N’Assembly of his resumption of duty from today. He receives briefing from the VP in a short while.”

Vice President Osinbajo reportedly arrived the president’s office at exactly 12.05pm apparently to formally brief on happenings in the country while he was away.

President Buhari returned to the country on Friday after spending 50 days in London for an undisclosed ailment.

Addressing his cabinet and other top government functionaries immediately after he returned, the president admitted that he had not been this ill his entire life and have never had to go through such medical procedures as blood transfusion and all.

He however said he was feeling lots better and will continue his drive for a positive change in Nigeria, adding though that he could return to the UK “in a few weeks” for routine medical checks.
