The Public Accounts Committee has today heard that the cost of the new National Children's Hospital could reach at least €2 billion.

We were joined by Jimmy Sheehan, retired orthopedic surgeon and developer of Blackrock, Galway and Hermitage Clinics, and Peter Greally, Chief Clinical Director of the Children's Hospital Group, to discuss what can be done about the debacle.
