The Dáil is due to conclude its debate on the Fine Gael motion of no confidence in the Minister for Finance tonight and hold a vote on the matter.
The house held an often heated discussion on the motion - which charges Mr McCreevy with "mismanaging" the public finances - last night.
Deputies from the Opposition benches made repeated demands for the minister to resign, while he was strongly defended by the Taoiseach, Mr Ahern, and the Tánaiste, Ms Harney, who sat beside him during the debate. "It is an attempt to whitewash the fact that Fine Gael treated the General Election like an auction," Mr Ahern said.
The Fine Gael leader, Mr Enda Kenny, renewed his attack on Mr McCreevy on RTE's Morning Irelandtoday, claiming that Government policy means "confidence in the country has been destroyed across a whole range of businesses".
"[Some] €4800 million built on the backs of Irish workers as a surplus has now been frittered away with no increase in the quality of public services," the Mayo TD claimed. "It means that the Government's own target of getting spending down to 14 per cent over the year is in tatters."
Mr Kenny claimed that the figures released by Mr McCreevy "have been out by €250 million a week" and the Taoiseach is not able to defend his minister for finance "because he is off the rails".
Fine Gael's finance spokesman, Mr Richard Bruton, said last night Mr McCreevy's "failures" will cost this economy jobs. "Redundancies are already up by 46 per cent in the past 12 months and running at a rate of 500 per week," he said.
The Labour Party leader, Mr Pat Rabbitte, accused Mr McCreevy of cheating in last year's Budget in order to secure victory in the General Election.
