David Cameron was "very sad" on Wednesday at the Church of England's decision not to accept women bishops.

If there is one lesson that the PM is learning a lot lately, it's that being ostensibly the most powerful man in Britain doesn't mean you always get your way.

Some might say that only three things make Cameron happy. Riding horses, long distance hide-and-seek with his kids and selling arms to dictators.

The rest of the time the PM has a uniquely reddish grey spectrum of emotion that ranges from "extremely angry" to "very, very sad".

Rather than spending thousands of pounds polling politicians and the public, a more accurate indication of Britain's condition could appear to be found in the size of the PM's frown.
