President Muhammadu Buhari has travelled to London for medical follow-up.

His spokesman Femi Adesina, in a statement on Sunday evening said the length of the President’s stay in UK will be determined by his doctors.

This is coming just a few days after a State House correspondent reported that Buhari’s absence from public functions could be as a result of his deteriorating health.

Chief Security Officer to the President, Bashir Abubakar, described the report as “sponsored” and “ill-intended” and consequently dis-accredited the reporter and threw him out of the State House.

In the statement announcing the President’s travel, Adesina, noted that Buhari “had planned to leave Sunday afternoon, but decided to tarry a bit, due to the arrival of 82 Chibok girls who arrived Abuja earlier in the day.”

“The president wishes to assure all Nigerians that there is no cause for worry. He is very grateful for the prayers and good wishes of the people, and hopes they would continue to pray for the peace and unity of the nation,” the presidential spokesman added.

He also added that “President Buhari has transmitted letters about the trip to the senate and the House of Representatives, in compliance with section 145 (1) of the 1999 constitution.”

Vice-President Yemi Osinbajo will resume in acting capacity as president, as long as Buhari is away, Adesina added.

When the President returned to the country on March 10 after spending 49 days in what was initially intended to be a 10-day medical leave, Buhari told the people that had come to welcome him that he has never been “this sick in my entire life,” adding that there may be need for a follow-up trip in the coming weeks.

Earlier in the day, the President had met with the 82 Chibok school girls released by the Boko Haram terrorists on Saturday.

Details of the meeting remain sketchy as journalists were barred from covering it.

Only a cameraman from the Nigerian Television Authority, NTA, the President’s personal cameraman, Bayo Omoboriowo, and some international journalists were granted access into the official residence of the President where the event took place.
