While I’m on the subject of the Poles in the UK Parliament, I’ve got a question. Has Denis MacShane’s slide into absurdity been a gradual, steady thing, or has it gone in fits and starts? If the latter, are there key moments that one needs to know about? I can remember that I once used to think he was a more intelligent than average politician whose opinions were worth paying attention to — but that seems like a very long time ago now. Maybe it was just because he appeared to know something about European social democratic politics, and I have an unreasoned prejudice in favour of people who appear to know something about European social democratic politics?
