'Tough decisions will have to be made.' - Alliance Minister Stephen Farry on health budget
Potential cuts to the health service outlined in a paper seen by the BBC could be "catastrophic" to patient care, a Northern Ireland GP has said.
Dr Tom Black said he had "never seen anything as threatening for the health service".
The paper shows that cuts could restrain pay for health sector staff, lower the number of agency staff and reduce spending on home care packages.
The Health Minister Edwin Poots said his department faces a £140m shortfall.
