A Scoping Inquiry's to be set up into what happened at Cervical Check.
Health Minister Simon Harris is bringing terms of reference for the investigation to Cabinet for approval.
It'll look at the non-disclosure to patients of the Cervical Check smear test audits, management of the scheme, and will try to establish who knew what in the Health Service Executive and the Department of Health.
It will also examine at the tendering and operation of the labs used by Cervical Check to examine smear tests.
Work will start this week and the inquiry will work with Vicky Phelan and any other women affected.
Minister Harris hopes the inquiry will report back in June.
He is also going to announce plans to appoint a new HSE board, and introduce legislation to allow him to do that.
Plans for mandatory open disclosure will also go to Cabinet this morning.
