The board of Crumlin Children's Hospital believes that developing the new national children's hospital on the campus of St James's Hospital represents the best option for the care of children.

Speaking on RTÉ's News At One, the board's chairman, Archbishop of Dublin Dr Diarmuid Martin said the St James's site had the most going for it.

Dr Martin said: "The basic point is where are the best synergies available beween a large general hospital ... and the specific needs that would come up with a children's hospital.

"The best match, in the view of the board of Crumlin hospital, is in the combination that St James's offers.

"Look and see, with the menu of lead services and national centres which St James's has and see if that is the best match for the needs of a children's hospital."

St James's Hospital has made a submission to the Government's review group, indentifying a site on its campus that is available for the development of the children's hospital.

The move followed a refusal by An Bord Pleanála of planning permission for the Mater site, on grounds of height and density.
