Expenses is the easiest thing in the world to fiddle and I can put hand on heart and say that I never have; that may be though my own moral ethics or it may be that I am truly of the belief that 'you always get caught'; as your two ex managers can probably verify Peter. Presumably, and I don't know if this is the case, but MP's must have to keep all receipts and have a full audit of their expenses on a yearly basis.. I don't mean an overview, I mean a detailed analysis. I know for example, I could add 5 trips to London on my expenses form and no one would ever question it. I would imagine that FTSE100 companies, being so big, cannot spare the time and resource to do so effectively. Surely, an MP's office wouldn't have the same difficulty?
