President Bola Tinubu has ordered a recall of Nigeria's ambassadors the world over with immediate effect, his spokesman said on Saturday.

"The president is determined to ensure that world-class efficiency and quality, will henceforth, characterize foreign and domestic service delivery to citizens, residents and prospective visitors alike," presidential spokesman Ajuri Ngelale said.

Nigeria's United Nations permanent representatives in New York and Geneva are exempted from the "total recall" due to the upcoming United Nations General Assembly (UNGA) later in the month, Tinubu's office said in a statement.
