We should have a discussion about unvouched expenses. The unvouched one is always the cheapest option for the taxpayer but if somebody says I should be on the fully vouched amount at a higher level, that will cost the taxpayer €961,300. If we are making a recommendation, we want verification, auditing and vouching but we would also want to watch the additional costs.

The Houses of the Oireachtas Service engaged Mazars to carry out the audits in respect of 2011.
