Labour Party leader Mr Pat Rabbitte said today the Sinn Féin leadership had been given a wake-up call to sever their ties with the IRA.
Labour Party leader Mr Pat Rabitte: IRA must be stood down
He said there was "no immediate prospect" of doing business with Sinn Féin, and added the scale of money laundering across the State should force Mr Gerry Adams and Mr Martin McGuinness to distance themselves from the IRA once and for all.
"If that doesn't bring members of Sinn Féin to their senses and realise the nature of the organisation that they are members of then nothing will," he said.
Mr Rabbitte said the only option for the republican movement was to "stand down" the IRA and discharge their obligations under the Belfast Agreement.
He said republicans would be left facing a public test of their bona fides and commitment to democracy.
"They can do that by a unilateral act of decommissioning, advising the PSNI of who are the murderers of Robert McCartney," he said.
Progressive Democrats Senator Mr John Minihan challenged Mr Adams to name names after he told a republican commemoration in Strabane yesterday that rogue members would be "expelled from our ranks".
Mr Minihan said: "Fine words indeed Mr Adams, but are we really going to see any action?
"If Mr Adams really believes this, then can he tell the public what members of Sinn Féin/IRA have already been expelled for engaging in criminal acts?"
Green Party finance spokesman and Cork South Central deputy, Mr Dan Boyle, said the Irish Financial Services Regulatory Authority should investigate the alleged money-laundering activities in Cork.
