The Cabinet has confirmed this lunchtime that the banking inquiry will get under way next week, and Labour's Ciaran Lynch will chair the inquiry.
The Government Chief Whip Paul Kehoe will move the motion in the Dail on Tuesday, with the inquiry to be established immediately afterwards.
Mr Lynch said its priority must be to establish exactly what happened that led to the collapse of the banks.
He would not be drawn on what individuals should appear, but said he doesn't think those invited would need to be compelled:
"It would be beholden on the political personnel of the day to turn up - it would certainly be beholden on any public servant," he said.
"I don't envisage a situation that people who were in very, very responsible roles. .. would fail to come before a committee."
