The Taoiseach and Health Minister must make statements on what they knew of an alleged strategy to deny families access to refunds of illegal nursing home charges.
Sinn Fein is making the call after revelations in the Mail on Sunday that successive governments allegedly had a secret plan to block refunds.
It's alleged the state faced a 12 billion euro liability in compensation for families who were wrongly charged for the care over 30 years.
The party's spokesperson on Health David Cullinane says it's claimed senior ministers were aware:
'What's being alleged is that a number of Ministers would have known and obviously very senior people in the department and at the highest level of Government, including the Taoiseach Leo Varadkar.
That's what's being alleged, That's why this is so serious.
If at any stage the government was involved in any covert plan to deprive people or deny people their just entitlements and then force them through the courts.
If that is what happened, and that is what is being alleged in this article, then that's profoundly serious'
