Pembrokeshire Assembly Members have voiced concern about an apparent "done deal" that would see the new super health trust based in Cardigan.

The trust, which becomes operational in April under the name Hywel Dda, is being formed by merging the three NHS trusts of Pembrokeshire, Carmarthenshire and Ceredigion.

It has now emerged that Cardigan is being considered as a location for headquarters of the new three counties super-trust.

Health minister Edwina Hart wrote to Cardigan's AM Elin Jones saying: "I have discussed the siting for the new headquarters with the chairmen of the existing trusts, including my thoughts that it could be located in Cardigan."

AMs Angela Burns and Paul Davies are worried that a full inquiry into the best location for the Hywel Dda Trust headquarters has not been held.

Preseli Pembrokeshire AM Paul Davies said: "I am concerned that Ms Hart favouring Cardigan means that this it is effectively a done deal.

"We must make sure that all the options are looked at and this move makes economic sense."

South Pembrokeshire and Carmarthen west AM Angela Burns added: "I strongly feel that the new trust should be based at one of the existing three trust offices.

"The whole point of this exercise is to save money and this will not happen if they start building or renting new offices."

"I also believe that the new offices must be based at the sharp end - in other words the hospitals - so that they won't get divorced from the reality of providing health care."
