Following growing outrage over the spending habits of councillors, Toronto Mayor David Miller has asked for a report from the clerk's office on how to improve the expense policy.

Miller wants suggestions on how to streamline the numerous spending policies and make one simple guideline.

The move could reduce the number of questionable items that have surfaced on councillors' expense forms.

Some of the purchases that came to light on Monday include lavish dinners for staff, late-night limo rides, booze, cappuccino machines, office furniture and CDs.

A Miller spokesman said the mayor isn't judging councillors, who are given a yearly budget of $53,100.

"He's not their father, he's the mayor," said Stuart Green.

"It's up to them to spend their discretionary budgets how they see fit. If it's not appropriate, others will judge them. The mayor is not judging them on their expenses."

On the questionable expenses, Green admitted "there are clearly some improvements that need to be made based on what we're seeing."

The city's auditor general, Jeff Griffiths, told CTV News there is significant public and political interest in the spending issue, and an audit may be required.

Two prominent penny-pinching councillors, Doug Holyday and Rob Ford, are calling for audits of all councillors' expenses to reduce what they say is out-of-control spending.

Holyday has called for audits to be conducted four times a year.
