The deputy leader of the Progressive Democrats, Liz O'Donnell, has said her party is costing possible reforms to the housing stamp duty system.
She was speaking a day after PD leader Michael McDowell said the State did not need what he said was the massive level of funds generated by stamp duties.
Speaking on RTÉ Radio's News At One, Ms O'Donnell rejected criticisms that the PD stance had not been thought out properly.
She said her party was examining the possibility of reducing stamp duties, not abolishing them.
Earlier, a senior Fianna Fáil politician criticised Mr McDowell's stamp duty proposal.
Seán Fleming, Chairman of the Dáil Select Committee on Finance and the Public Service, said any reduction of revenue had to be compensated for in other areas.
Mr Fleming said he would have been far more impressed if Mr McDowell had come out with a more thought-out proposal and he looked forward to learning of its detail.
He described the proposal as 'a little bit of electioneering' by the PD leader and suggested that Mr McDowell was looking to his electorate in Dublin South East and not at the broader picture.
