Remember that according to UK practice - it is not criminal to be incompetent as a minister - personal responsibility due to ignorance and lack of competence are excempt for ministers in the UK. This is the only group of professionals who are specifically excempt by law from any personal responsibility due to grave incompetence. All others can be penalized... the further down on the food chain - the more likely that this happens...

so at the end of the day it would be the clerk who is found 'guilty' and not his manager...
