Although I have been active in politics for a long time I was elected in 1999 and am perhaps more aware of the boundaries than people who entered politics 20 or 30 years ago when there was a large grey area. Some people were corrupt and others were caught in the middle. At times I am excessively conscientious about this. For example, two Christmases ago I returned some bottles of wine to a developer and then wondered whether I was being overly zealous. It was probably an insult to the person concerned.
