Thank you. I wasn't aware of the change from six weeks to 16 weeks and, as you say, I would've thought there would be an all-Wales standard. So, I will certainly ask the health Minister to look at what you've just come forward with, because I do think there would need to be an explanation if it had gone from six weeks to 16 weeks for pre-operative assessments, because, obviously, if somebody has a pre-operative assessment, then their health could change considerably in that length of time. I'm not aware if there is an all-Wales standard, but I would've thought there would be, so I will certainly ask the Minister for Health and Social Services to have a look at that.
