The Health Minister is coming under further pressure to explain the circumstances which led to the Slaintecare resignations.
Last week, Director Laura Megahy and Chairman Professor Tom Keane stepped down from their roles.
They resigned after expressing frustration at the lack of political will to end the two-tier health service.
MEP Billy Kelleher who was a member of the Oireachtas Committee which established Slaintecare, says Minister Stephen Donnelly has some important questions to answer.
