‘They abolished the Human Rights Act” sounds like the first sentence of an Aldous Huxley novel. The Conservatives actually campaigned on a manifesto pledge to get rid of human rights and people voted for it. As electoral choices go, it’s not far off choosing to be ruled by a dry, whispering voice taunting you from an antique mirror.

Here, in what may well be the final years of our civilisation, I would like to ask a question that has been worrying me for some time. What if David Cameron is a genius? A shrewd and malevolent psychopath who thinks two moves deeper into the game than any of his opponents? What if there sits in Downing Street today a modern-day Moriarty, living in a world where his schemes are only kept in check by the deductive brilliance of Harriet Harman? As Holmes would say, look at the evidence. Cameron has managed to set England against Scotland, Scotland against Labour. He has given his enemies the referendums they asked for, and won. He has left Nick Clegg looking like one of those terrified mouse faces that you find in an owl pellet. He has successfully pursued an agenda more radical than Thatcher’s with less popular support than John Major.

What if David Cameron is an evil genius?
