Auditor general Sheila Fraser is ignorant of the fact why MPs would save her from auditing parliamentary spending that is now reported to touch nearly $530 million a year.

Last June, Fraser reported meeting with the board of internal economy, the secretive all-party committee that ignores spending on Parliament Hill, and laid out her plans for an audit.

During the Tuesday' news conference that witnessed her most recent audits, she cited hopes that MPs will give her grant her with an approval.

"The combined Houses of Parliament spend some $500 million a year," Fraser posted. "We think that it is important for accountability purposes that there be an audit done. As well, we like to think that audits are there to help improve management processes." Fraser reveals that as recently as 2009, both the Commons and the public works department came up with an analysis of the risks, cost, and timing of developing a new building.

However, Marcel Proulx, the Liberal MP, the speaker for the board of internal economy, remained silent on Tuesday when asked to explain the reason behind MPs might rejection over Fraser's request.

"That is still under discussion by the board," he quoted. "Until we've made a decision, you'll have to wait on that."
