Wexford Independent TD Mick Wallace has resigned from the Technical Group of TDs.
There had been confusion over his status last week after the embattled TD had said he would “step back” from membership of the alliance.
However, group chair Finian McGrath announced this evening that Mr Wallace had resigned fully.
The Technical Group comprises a number of Socialist and non-party TDs who band together to secure speaking time in the Dáil.
Mr Wallace is under investigation for deliberately understating the tax liabilities of his construction company, which is now in receivership and unable to pay a €2m Revenue bill.
