In New Zealand there is currently quite a bit of huffing and puffing about the revelation that the Mayor of Auckland had been having an extra-marital affair for a couple of years. He has refused to resign and his supporters, including his three daughters, say that this is a private concern.
However, his campaign for the mayoralty was based on a) his Christianity and b) his happy marriage. Also, some of the adultery – and he doesn't deny that he had sex with that woman – took place on council time and in council property. Finally, he was in a position of authority over her.
It's not exactly on a par with Bill Clinton and Monica Lewinski, although in both cases it was the woman who let the cat out of the bag, but there are obvious parallels.
I think he should resign because of the points mentioned in my second paragraph. What do you think?
