Cackiavellian (adj): Acting in a Machiavellian manner, while being so cack-handed about it that everybody sees through your deception. The worse of both worlds – transparent dishonesty. Usually applied to politicians, as befits a neologism coined for that class. The etymology is brand spanking new, since it comes from the splendid Marina Hyde’s column in today’s Guardian, Rupert Murdoch may be a monster but David Cameron and co are far worse. She is, of course, referring to our “political elite” – an oxymoron if ever I heard one.
