The secretary general of the Confederation of African Football (CAF) Hicham El Amrani on Sunday, tendered his resignation to the continent's football governing body just over a week after elections ousted long-standing president Issa Hayatou from power.
El Amrani, in a letter to African football associations, said he would be departing on Monday, but gave no reason for his decision.
The 37-year-old Moroccan had served as secretary general for the last six years.
He, alongside his former boss were facing investigations by Egyptian authorities.
Hayatou's tenure as CAF president ended 10 days ago at elections in Ethiopia, where six of his allies on the body’s executive committee also lost their positions.
The Cameroonian had served as president for 29 years.
Meanwhile, new CAF president Ahmad Ahmad is expected to meet staff members in Cairo on Monday.
