If there was ever a perfect example of Tucker’s Law, then the front page of this morning’s FT would be it. With Cameron finally waking up to the fact that his position as leader of a Eurosceptic party is being openly discussed, he’s come out guns blazing in the Times, claiming he will not sign any piece of paper that threatens the City or British interests as Europe begins the process of treaty change. It will annoy the Europeans and it’s not far enough for most his party, but then Ken Clarke went and made it a whole lot worse:

“Ken Clarke has put himself at odds with David Cameron by saying Britain should focus on “how to maintain the financial stability of the western world” at this week’s European Union summit … Asked in a Financial Times interview whether the summit was a good moment to extract concessions … Mr Clarke said: “No, no.””

Guido thought the turn of phrase was “no, no, no”? This is the latest in string of grenades Clarke has been willing to throw. They would be gaffes if it was not so obviously deliberate. IDS is apparently on the warpath too…
