It has emerged the State Agency Forfás spent more than €1.4m last year renting offices that were never used.
The figures, which are contained in the agency's Financial Statements for 2012, have prompted Fianna Fáil to call on the Public Expenditure Minister Brendan Howlin to explain why this is happening and to take action.
The party's spokesperson on Public Expenditure and Reform, Sean Fleming, said he fears other State agencies may also be wasting taxpayers' money.
