President Muhammadu Buhari has been diagnosed with cancer, according to sources at the London hospital where he reportedly underwent medical check-up.

The Nigerian leader arrived in London on Monday (June 6) on a 10-day vacation, his Spokesman Femi Adesina announcing a day in advance: “During the holiday, he will see an E.N.T. specialist for a persistent ear infection. The President was examined by his Personal Physician and an E.N.T Specialist in Abuja and was treated. Both Nigerian doctors recommended further evaluation purely as a precaution.”

A source told News Express this morning: “President Buhari went for check-up hours after he arrived in London. The hospital has discovered the cause of Mr President’s illness to be cancer of the ear and brain. Let us start praying.”

The source, who is well connected in government circles, gave the name of the hospital as Royal Hospital London. He said he was given the information by medical sources at the hospital who have been his longtime friends.

Just yesterday the news filtered in that Buhari has also been battling “a terrible cough” and may need to spend more than 10 days in London to enable him seek adequate medical treatment.

Mr. Adesina, however, continues to insist that the President “is fit as a fiddle.”
