David Cameron, in response to Angus Robertson's question about the likely closure of RAF Lossiemouth at PMQs -
"If you had an independent Scotland, you wouldn't be flying planes, you'd be flying by the seat of your pants."
A sneering reply that was the cue for lots of equally sneering laughter from the Tory benches - but let's just examine this for a moment. Who are they actually sneering at? Not the SNP, that's for sure - Cameron wasn't particularly talking about an SNP-run independent Scotland, or even a Labour-run independent Scotland. He was simply mocking the capacity of Scots to govern themselves under any circumstances.
Now, you can see how Cameron might have been deluded into thinking that he's onto a winner here. After all, Labour have been talking Scotland down for decades and have more often than not been richly rewarded for their troubles. But the difference is that it's usually Scottish Labour figures who are the front for the talking-down operation. Why else does it infuriate us so much when Jackanory Jim does his "as a Murphy, it breaks my heart to say that an independent Scotland would be as rubbish as Ireland" routine? Because we know that the spinning of such yarns does get under people's skins, and it does ultimately sap this nation's morale. But hearing an Old Etonian Tory PM repeatedly sneer at "you" Scots will, I suspect, have a somewhat different effect.
Great politics, Dave. Don't stop.
