The Taoiseach has been asked to give a detailed explanation of his contact with senior officials in Anglo Irish Bank during the banking crisis.
Yesterday, the Sunday Independent published details of an email which showed the then-leader of the opposition contacted a senior Anglo official in 2008 - before the bank was nationalised - to brief them on Government policy.
Before now, Enda Kenny had only revealed one meeting with Anglo in 2008.
A spokesman for the Taoiseach has "completely rejected" any allegations that Mr Kenny misled the Dáil over his communications with the bank.
Fianna Fáil's Timmy Dooley has now accused the Government of hypocrisy.
"He was at pains to point out that an axis of collusion existed between the party which I represent and the banking fraternity, without a shred of evidence to sustain that argument," he said.
"So I think he is the one who has made the political charge. Information has now come out which, I think, calls into question his judgement as he was, as leader of the Opposition, and I think he needs to clarify that now most particularly at a time when he is the serving Taoiseach of this State."
