Cabinet will be updated on plans for an external review of the governance at RTÉ this morning.

Media Minister Catherine Martin will also brief colleagues on her plans for the terms of reference of the review.

While final terms of reference for this independent review into RTÉ are likely to take a number of days to put together, Minister Martin will outline the broad strokes to Cabinet this morning.

It is expected the review will examine whether RTÉ's governance framework culture is fit for purpose.

It will review financial management at the broadcaster - including the use of barter accounts, commercial outside agencies and agents.

The workplace culture in RTÉ will also be put under the microscope including the relationship between senior management and staff.

Last night the three coalition party leaders discussed the plans, with all expressing concern about the revelations regarding undisclosed pay to Ryan Tubridy.

The Media Minister has also written to the Chair of RTÉ Siún Ní Raghallaigh and the Deputy Director-General Adrian Lynch, stressing the importance of full and open engagement with the board, the executive team and other senior managers.

Many of those will be called before Oireachtas committees in the coming days, and the issue will feature heavily in both the Cabinet and Dáil proceedings today.

The RTÉ Board has pledged to release a "comprehensive statement" setting out everything it knows about the pay scandal later.

It comes just a day after former RTÉ Director-General Dee Forbes resigned her position with immediate effect.

Ms Forbes said the payments were negotiated prior to her arrival at RTÉ but noted that as Director-General, "I am the person ultimately accountable for what happens within the organisation".

She also hit out at the board, insisting it had "not treated me with anything approaching the levels of fairness, equity and respect that anyone should expect as an employee, a colleague or a person".

"I am deeply sorry for what has happened and my part in this episode and for that I apologise unreservedly to everyone," she added.
