ABUJA (Reuters) – Nigeria’s President Muhammadu Buhari said there was no cause to worry about his health but he had to stay longer on medical leave in Britain than planned, the presidency said on Tuesday.

“During his normal annual checkup, tests showed he needed a longer period of rest, necessitating the President staying longer than originally planned,” the presidency said in a statement.

“President Buhari wishes to reassure Nigerians that there is no cause for worry,” it said.
