Nigerian President Muhammadu Buhari is expected to travel to London for medical check-ups for approximately two weeks, local media reports.
The president has been criticised for failing to transfer power to his deputy on an interim basis as constitutionally expected.
Mr Buhari has also been heavily criticised for seeking treatment abroad while Nigeria’s healthcare system suffers from mismanagement and under-funding.
The Nigerian president arrived in Kenya on Tuesday to attend the United Nations Environment Assembly (UNEA) and celebrate the 50th anniversary of the United Nations Environment Programme.
He is expected to leave Kenya and head straight to London.
