Wagging Finger: If it's under the auspices of the AOC you are talking about, then the accountable manager can only be the license holder which is the CC, no? He/she cannot delegate this responsibility therefore putting a layer between him/her won't work.
I accept and understand that the NPAS team have to fall into line with the Yorks management system, but an ACC??? Walnut and sledgehammer come to mind. What's wrong with another supt?
