The Dáil's Committee on Members' Interests will decide today whether to launch an inquiry into the tax affairs of Indepdent TD Mick Wallace.
Last night the Taoiseach warned the coalition 'stands ready' to put down a motion of censure in the Wexford TD.
Mr Wallace made false VAT returns and has entered a €2.1m settlement with Revenue, though he says it's unlikely to be paid.
Amid fears that any slap on the wrist of Deputy Wallace could prejudice any legal case, politicians decided not to proceed to censure the Wexford TD yesterday.
But now a decision has to be made by the Members' Interests Committee - which looks at the conduct of TDs - about whether he has a case to answer.
The committee could decide to take no action, refer Mr Wallace's admission of tax dodging to Gardaí or the DPP, or launch an investigation into whether Mr Wallace has made any attempt to pay the money while a TD.
Last night the Taoiseach warned Deputy Wallace's position was of "the utmost seriousness" and insisted the Government "stands ready" to put forward a motion of censure if required.
