Cabinet Ministers are facing pressure not to sign off on proposals from Health Minister Stephen Donnelly to develop the National Maternity Hospital at the St Vincent's Hospital campus.
Minister Donnelly is bringing the memo to Cabinet on the basis that protections have been put in place to ensure clinical independence at the new maternity hospital and it will lead to a substantial improvement in women's healthcare.
But Social Democrats co-leader said Cabinet Ministers should not sign off on the deal before greater scrutiny is carried out.
