It is the policy of the Welsh Government that care should be provided as close to home as possible. And there is a recognition that, for some services, that will mean fewer specialist centres. But, in terms of any particular point about how many emergency departments there could or should be, the Welsh Government doesn't have a magic figure in its mind about the number of departments there could or should be. These are difficult questions, which are reliant both on the need of the population, but also on our ability to recruit the right numbers of staff to provide the right service that people rightly expect.
