The acting chair of the Irish Fiscal Advisory Council Sebastian Barnes said there were questions about how the State's plan to transform healthcare, called Sláintecare, would be funded.
He told the Oireachtas Covid-19 committee that the plans in the programme for government were welcome and affordable as long as the right fiscal decisions were taken.
The Council told the committee that Sláintecare would add €3 billion annually to spending. Representatives of the Council were asked to provide further details of the estimates by Róisín Shorthall of the Social Democrats who she said the costings were very much out of line with the figures forecast in recent years.
