Nigeria's outgoing President Goodluck Jonathan has warned that his ministers will be "persecuted" once his successor Muhammadu Buhari takes office.
Mr Jonathan's comments seem to suggest that he fears corruption investigations will be launched against his allies, a BBC correspondent says.
He became the first Nigerian leader to give up office, after losing elections to Gen Buhari in March.
Mr Jonathan said some of his friends had "abandoned" him after his defeat.
Gen Buhari, a former military ruler, is due to be inaugurated on 29 May.
