Dublin West TD Mr Liam Lawlor resigned yesterday from two Oireachtas committees, ahead of a vote to remove him from them in the Dail today.
The Government has tabled a motion for today, calling on Mr Lawlor to co-operate fully with the Flood tribunal within the time-frame set out by the High Court, and to resign as a TD if he does not do so.
There was also a motion to replace Mr Lawlor on the Oireachtas Committees on Public Enterprise and Transport and on Finance and Public Service with Fianna Fail TDs.
Following Mr Lawlor's two letters of resignation to the committee chairmen yesterday, this motion will now simply nominate Mr Ben Briscoe and Mr Sean Power as replacements.
Fine Gael yesterday tabled an amendment to the substantive motion seeking Mr Lawlor's resignation.
It said the imposition of a fine on Mr Lawlor by the High Court and his jail sentencing for contempt, and his consistent failure to fully co-operate with the tribunal, "renders his continued membership of Dail Eireann untenable and Dail Eireann calls on him to voluntarily resign his membership".
The committees motion will now be taken without debate, so it is expected that up to three hours will be devoted to debating the resignation motion.
The Labour Party has also tabled an amendment calling on Mr Lawlor to voluntarily resign. Deputy leader Mr Brendan Howlin said the Government motion, "which essentially sought to put on the long finger any recommendation regarding the position of Mr Lawlor, was a totally inadequate response to serious contempt that he had shown for the tribunal and for the orders of the High Court."
The Socialist Party TD, Mr Joe Higgins, is to picket Leinster House today over his suspension from the Dail. He has been barred ail for the first day of the new session and he said he would not be able to speak on the Lawlor debate as a result.
Mr Higgins said he was suspended before Christmas "for the crime of wishing to ask the Taoiseach on the Order of Business for some speaking time in a debate on the proposals emerging from the Nice summit".
