The reason David Cameron must absolutely hate Twitter right now

David Cameron delivered his speech at the Conservative Party conference on Wednesday in which he spoke up social mobility, equality and opportunity.

The prime minister may have won a lot of praise from the so-called "commentariat" on Twitter - for positioning himself further towards the centre-ground and thus weakening Labour's supposed electability - but the social network isn't exactly a joyous place for him right now.

Since the release of the unauthorised biography Call Me Dave, written by former Tory party deputy chairman Lord Ashcroft and journalist Isabel Oakeshott, each tweet the prime minister posts has been met with a barrage of pork-related puns.

After one section of the book alleged, with spurious sourcing, that the prime minister may have once done something bad with a dead pig as part of an initiation ceremony whilst at university, people have been mocking him relentlessly.

Not that it's seemed to bother him too much. As well as cracking a joke about the book in his speech, Cameron also warned his political rivals that: "Britain and Twitter are not the same thing."
