I think it is likely to have been a one-off, but part of the point about the chief executive writing to all health boards is to ensure that it has been a one-off. If there are other issues, then we want those to be uncovered and dealt with, because the Wales Audit Office investigation revealed a picture that is simply not acceptable and not in line with the established processes and recommendations, and, again, the chief executive’s letter to every chief executive in NHS Wales makes very clear that we expect those standards to be strictly adhered to.
