Diolch, Llywydd. First Minister, we accept that services have to change and that we can't deliver health in the same way we did 70 years ago. However, any change has to be based upon clinical need and be clinically led. By that, I don't mean the clinical director of the local health board. Change needs to be driven by the doctors and nurses and supported by doctors and nurses. I've been contacted by a number of staff protesting about the merger of wards at Morriston Hospital, which has proceeded without the support of clinical staff. Staff believe the change is financially driven. First Minister, can you guarantee that financial pressures will not lead to further such changes in future?
