The Taoiseach Leo Varadkar has said he is 'very concerned' at recent information set out by RTÉ, and the subsequent suspension of its Director-General Dee Forbes.
Ms Forbes has been suspended, amid fallout from the payment of hundreds of thousands of euro more to presenter Ryan Tubridy than the broadcaster had declared to the public or the Oireachtas.
Mr Tubridy has said he apologises unreservedly for not querying 'incorrect figures' published by RTÉ about his salary.
He will also not broadcast his radio show next week.
In a statement, Mr Varadkar said all of the matters involved will have to be examined, and "remedial steps" may be needed to restore trust and confidence.
"I am very concerned at the information set out in RTÉ’s statement and the announcement that the Director-General has been suspended," he said.
"On the face of it, there has been a serious breach of trust and truth between RTÉ and the Government, the Oireachtas and the people".
'Accountability and transparency'
It comes as a meeting between Media Minister Catherine Martin and Chairperson of the RTÉ Board, Siún Ní Raghallaigh, has been moved forward to Saturday.
Mr Varadkar said he will receive an update from Minister Martin after the meeting, and she will brief the Cabinet on Tuesday.
"At tomorrow's meeting, the Minister will be asking the chairperson to set out in detail the issues involved and the steps the RTÉ board is taking," he said.
"The Government considers it essential that we have the highest standards of governance, accountability and transparency from RTÉ and will consider what further action may be required.
"All of the matters involved will have to be examined and, perhaps, remedial steps taken to restore trust and confidence.
"It will be equally important for the board to demonstrate that it is putting in place appropriate structures and processes to prevent a recurrence.
"The public are right to expect high standards of transparency and accountability from RTÉ as it is extremely important that we can all have trust in our public service broadcasting," he added.
