The chairman of the Dáil's Public Accounts Committee has said that four more agencies which are believed to have breached public pay rules will be named tomorrow.
Fianna Fáil's John McGuinness says four whistleblowers have come forward to reveal top-up issues similar to those revealed at the Central Remedial Clinic.
The Committee is due to meet with representatives from the HSE and Department of Health at a meeting tomorrow morning.
And PAC chairman McGuinness says the agencies in question will be named during that hearing.
"We would hope that we would name the agencies… if they're non-compliant, well then they need to either comply and explain, in terms of a business case," Mr McGuinness said.
"But I understand that up to now only one agency has put forward a business case, and we will be seeking clarification on all of this.
"It is a €1.6bn fund and it needs far greater accountability and transparency than what we have seen to date."
