The Health Minister says it's "absolutely the case" that the new National Maternity Hospital will be fully independent, and offer all services.
Cabinet last night delayed signing off on the relocation to St Vincent's campus, with a number of ministers seeking further detail on the plan.
Stephen Donnelly has offered to appear before the Oireachtas health committee to answer questions.
He says the delay's necessary because of the "genuine concerns" people have about religious interference in the project.
"They want reassurance, they want absolute reassurance that the new hospital will be fully independent, that it will be clinically independent, that it will be operationally independent, and that it will offer all services.
"That is absolutely the case."
