Fiji's president, Ratu Josefa Iloilo, will appoint an acting vice president by promulgation this week.
This has been confirmed by the secretary to the president's office, Rupeni Nacewa, and the minister for Fijian affairs, Ratu Epeli Ganilau.
Mr Nacewa says the president's office is working on the appointment as the great council of chiefs has been suspended by the interim prime minister, commodore Bainimarama.
Mr Nacewa says the vice president would act as president when Ratu Josefa goes overseas for a medical review, which is expected to be mid next week.
Ratu Epeli Ganilau says commodore Frank Bainimarama had already announced last week that someone would be appointed to act as president by promulgation in the absence of the president Iloilo.
He says president Iloilo will make the nomination of the person who will be promulgated to act.
Because of the coup, there is no speaker of parliament who could act as president.
