The Labour Party has tabled a Dáil motion calling for the immediate reinstatement of the first-time house-buyers' grant.
The Seanad has also been served with a Labour motion condemning the abolition of the grant and calling for it to be re-introduced.
Labour's environment spokesman, Mr Eamon Gilmore, said today although there were many objectionable features in the Book of Estimates, published last week, the decision to abolish the grant has caused anger among those hoping to buy a house.
"The big winners from the abolition of the grant will be investors in the housing market. For several years investors have been outbidding first-time buyers for residential property. This was one of the major problems in the housing market which the Bacon reports attempted to address," Mr Gilmore said.
But the Minister for Finance, Mr McCreevy, is refusing to back down on the controversial decision to abolish the grant despite growing revolt on the issue from his backbenchers.
Mr McCreevy has received the backing of the Taoiseach, who has said the Government must move on from the decisions taken in last week's Book of Estimates.
Senator Brendan Ryan called on "Fianna Fáil malcontents" to voice their objections to the Government's decision in the Seanad debate tomorrow night.
He said those on the housing waiting lists are the main losers from the "appalling decision by this right-wing administration".
