It's always possible to change the process for background checks or security clearances, indeed, and I think I've tried to indicate a couple of times when it has changed over time. There is always a discretion to operate, as to how much you do, because all of this takes time and effort and delays the formation of cabinets, and so on.
I am not suggesting, and I've tried not to suggest anywhere, that somehow the existing system is perfect and never should be changed, but there are costs to changing processes. What I think Mr. Cullen referred to, the idea of looking at all at spouses and so on, has some implications for it that any Prime Minister would have to consider. Depending on the circumstances and what was being considered, I would give appropriate advice to the Prime Minister.
