Mark Oaten, a politician none of us had heard of until the week before last (when he briefly stood as a candidate in the Lib-Dem leadership election) has been visiting a rent boy on a regular basis. The media quaintly describe this as an "affair". Oaten equally quaintly describes it as an "error of judgement".
Even quainter is Oaten's characterisation of himself as a "tough liberal". I wonder if this is the same thing as a "compassionate conservative"? I expect it is.
And that both are much the same thing as an "opportunist".
