Fiji's minister for home affairs, Josefa Vosanibola, is reported to be working with officials from the President's Office over an alleged threat against the government by the military commander, Commodore Bainimarama.
Mr Vosanibola, who is the minister responsible for the military, has told Radio Legend that the President's Office will be speaking with Commodore Bainimarama about the allegations against him.
He says this will take place once Commodore Bainimarama returns from a medical review in New Zealand.
The chief executive of the Prime Minister's office, Jioji Kotobalavu, has alleged that the military commander had threatened to remove Laisenia Qarase's security detail if he was surcharged for the over expenditure by the army.
The ministry of finance has surcharged Commodore Bainimarama 12-million US dollars.
Commodore Bainimarama has protested to the finance minister about the size of the surcharge when other government heads have been surcharged only a few thousand dollars each.
