The chief executive of Fiji's tax authority says hundreds of people could be caught in an investigation into the abuse of travel expenses.
Sila Kotobalavu, who heads the Fiji Islands Revenue and Customs Authority, says there are cabinet ministers and chief executives of government departments who are believed to have evaded tax.
Mr Kotobalavu would not name those thought to be involved but they allegedly travelled economy class when the state paid for business class travel and then pocketed the cash difference.
The scam was highlighted when the Labour ministry chief executive was sacked after being convicted on similar charges.
Mr Kotobalavu says the problem could be even more widespread.
"Initially we were only targetting the chief executive officers as well as the cabinet ministers but now it's much wider. It also concerns some of the business people, business sector, so it's quite a wide net. It will be in the hundreds."
Mr Kotobalavu says they are urging travel agents to give them the names of ministers and chief executives allegedly involved.
He says if there is evidence of abuse, their names will be forwarded to the police.
