Nigerian President Muhammadu Buhari has extended his stay in London by a week for dental treatment, his aide has said.
The president had initially travelled to the UK capital last week to attend the coronation of King Charles III.
He was scheduled to return to Nigeria this week but will now stay on "at the behest of his dentist, who has started attending to him”.
“The specialist requires to see the president in another five days for a procedure already commenced," presidential spokesperson Femi Adesina said in a statement released on Tuesday night.
The president's extended stay has sparked criticism from some at home, who say that he should prioritise domestic issues - including its security challenges.
Since coming to office in 2015, Mr Buhari has travelled to the UK on a number of occasions for undisclosed medical reasons.
He is scheduled to hand over to President-elect Bola Tinubu on 29 May.
