- President Buhari's letter to the Senate says Vice president Osinbajo will remain in acting capacity until his return

- The letter also says the president cannot determine the date of his return because only his doctors can clear him for return

- The trip, President Buhari says, is a follow-up to an earlier one made in January 2017

The Nigerian Senate has read a letter from President Muhammadu Buhari on his travel to the United Kingdom for medical check-up.

The letter read was read by Senate president Bukola Saraki during plenary on Tuesday, May 9.

President Buhari said his trip to the UK is for a medical follow-up to his initial treatments and tests from his earlier trip to London.

The letter said length of the President's stay in London will be determined only by his doctors.

Acting president Prof Yemi Osinbajo is expected to continue to coordinate the affairs of the country until President Buhari is allowed to return to Nigeria by his doctors.

There was however a moment of drama after the letter was read when a senator, Mao Ohabunwa faulted the position given to Osinbajo in the letter.

Ohabunwa raised a point of order noting that there is no provision in the Nigerian constitution for a coordinating vice president as stated in the President's letter.

Personal Assistant to President Buhari on new media Bashir Ahmad denied that there is a vacuum in the leadership of the country as indicated in the report.

According to him, the vice president Prof. Yemi Osinbajo is now the acting president because President Buhari properly handed over to his deputy.
