Minister, while I accept that the investigation found no evidence of clinical harm and there was no indication that Cwm Taf had been deliberately trying to manipulate the figures, this does raise serious questions about the management of waiting lists, both in Cwm Taf and across all health boards. I'm sure all of us here can list examples of patients being removed from waiting lists because they didn't respond to a letter they may never have received. Minister, will you launch a wider investigation in waiting list management across all local health boards, and will you look at how technology can be used to improve the management of hospital appointments?
