The appointment of Gen. Sedki Sobhi today came one day after Egyptian strongman Field Marshal Abdel-Fattah el-Sissi announced his much-anticipated presidential bid.
Egypt's state news agency says El-Sissi took off his military uniform and showed up in Cabinet headquarters in civilian clothes.
Also today, Mahmoud Hegazy was appointed as chief of staff. His daughter is married to one of el-Sissi's sons. El-Sissi built popular support after the military overthrew Islamist President Mohammed Morsi in July last year.
