A bitter pill which has never been entirely swallowed by civic representatives (and politicians generally) is that the influence of locally elected councils over the appointed bodies who administer health care is minimal if non-existent. There remain occasional symptoms of acid reflux similar to the cross-party motion of no confidence in regional NHS management by three Conwy councillors but the general prognosis is otherwise unaffected.
Local Health Boards are instruments of the state, at least that's the theory, and are managed by non-partisan professionals who are in turn overseen by unelected appointees from 'appropriate' disciplines.
It may sound a lot like the quangos which administered Wales in pre-devolutionary days but it's all very different now, thank heavens. Time for more of the medication.
