Nigeria's President Buhari urged to take medical leave A group of prominent Nigerians has called on President Muhammadu Buhari, 74, to take medical leave, amid growing concern about his health. The group of 13 said they felt compelled to ask Mr. Buhari to heed the advice of his personal physicians by taking a rest to attend to his health without any further delay. Mr. Buhari took about seven weeks of medical leave in January, and flew to the UK for treatment. The President has however not been seen in public for about a week, and his absence from the cabinet meetings, as well as the weekly Friday Muslim prayers, has fuelled further speculation and rumours about his medical condition.
