Am I alone in being genuinely flabbergasted to discover that Alistair Carmichael was directly responsible for the 'Frenchgate' smearing of Nicola Sturgeon during the election campaign, and had lied through his teeth when asked for his version of events? He says that, if he was still a minister now, he would consider this to be a matter requiring his resignation - oh, how frightfully honourable. Well, he was a minister when he did what he did, and moreover he knew perfectly well that he had done what he did (even though the rest of us didn't), and if it's a hypothetical resignation matter now it was sure as hell a real resignation matter then.
So if he's such a man of honour, why didn't he come clean immediately and step down as Scottish Secretary? Oh, that'll be because he would have lost his Orkney & Shetland seat (which he only barely clung on to), and the Liberal Democrats would have been left with zero Scottish seats rather than one.
The fact that he still has the letters 'MP' after his name is a direct consequence of his act of dishonour. If he doesn't now resign from parliament (and he probably won't), nothing could better symbolise his party's thoroughly deserved demise - their only ghostly parliamentary presence is a disgraced politician who everyone knows shouldn't be there.
