We are doing it, Dirprwy Lywydd, because of the advice that we have received from those organisations in the best possible position to provide us with the advice we need—the royal colleges, the Vascular Society. They are the people who have explained to us the current arrangements are not sustainable. It is as a result of their advice that we will provide a service in north Wales that will be right for patients. Eighty per cent of services will continue to be delivered locally, but, when you need a specialist service, when you need a service where you need facilities and a team of people who carry out these procedures enough times during the year to have the professional accreditation that they need, to have the experience that keeps them performing at the best possible level of their professional skills, that's what people in north Wales will have as a result of these matters.
