A Fine Gael senator has been asked to withdraw remarks suggesting a "fraud" may have been committed in relation to Ivor Callely's expenses.
There is growing disquiet over a statement made by Senator Callely yesterday in which he said he had broken no rules in relation to €80,000 in expenses he claimed from an address in Cork, despite the fact that his constituency office is in Dublin.
Opposition parties have called on him to make a second, more comprehensive statement on the issue.
But in the Seanad, Fine Gael Senator Eugene Regan was ruled out of order for suggesting a fraud may have been committed.
