'No, maybe, oh go on then'
Ed Miliband is developing a nice line in the political use of humour - rather better than his deputy's.
Today the Labour leader suggested that, at last week's EU summit, the prime minister had turned "No, no, no" into "No, maybe, oh go on then" since he'd agreed to a 2.9% budget rise and not the freeze he'd promised.
His hope was to unsettle Tory Eurosceptics. He was helped by Charles Kennedy who praised David Cameron as "one long-standing pro-European... to another".
What's interesting is that - in public at least - they are, so far, refusing to be unsettled. Only Sir Peter Tapsell rose to his feet in the chamber today to demand a referendum.
Don't be deceived though - the issue of Europe put to sleep by David Cameron so successfully for so long is stirring again.
