Tánaiste and Minister for Defence Micheál Martin is expected to update the Cabinet on his intention to launch a public inquiry into systemic failings in the Defence Forces, which were highlighted by the Women of Honour group.
The move follows a recommendation of a statutory inquiry, by the Independent Review Group, which examined behaviours in the Defence Forces.
Last week, the Tánaiste indicated that he planned to recommend that a public Tribunal of Inquiry investigates allegations of emotional abuse, physical torture, bullying and sexual misconduct.
The Women of Honour group had said previously that a public inquiry was essential to restore trust - rather than a behind closed doors investigation.
It is understood that the terms of reference for the future public inquiry are still be drafted and will not be presented to Cabinet today.
