Ministers have signed off on an inquiry into the CervicalCheck scandal, with work on the investigation to get under way today.
Health Minister Simon Harris confirmed that Dr Gabriel Scally, from the Royal Society of Medicine in the UK, will lead the Scoping Inquiry.
The new inquiry will look at why 209 women were not told about their incorrect smear results.
It will also examine who knew what and when in the HSE and the Department of Health.
The inquiry is set to report in June.
Health Minister Simon Harris says it's a lot to examine in a short time frame, but added that those in charge will gather as much information as possible.
He told reporters: "While they're very ambitious terms of reference and very comprehensive, because they do have cross-party input, Dr Scally's job and Dr Denton's will be to answer as many as possible, to provide as much facts as possible.
"So when Government and the Oireachtas considers this issue again at the end of June, we can say 'well look: these questions have already been satisfactorily answered, we have the information (on) this, we don't have the information (on) this and can have I suppose therefore a more focused commission of investigation'".
