Whose tricks?

Stuart Weir (Cambridge, Democratic Audit): "LSD article plays tricks on Huhne's mind" ran the top-page article in yesterday's Sunday Times, drawing attention to an article Huhne had written on drugs while a student at Oxford in the 1970s, alongside a photograph that dubiously claimed to show him "battering down a door", and accompanied by a vicious op-ed cartoon suggesting that Huhne had killed off Ming Campbell's leadership and a very positive profile of Nick Clegg, the rival candidate for the Lib Dem leadership. (The Observer also ran a kind profile of Clegg.) Who is playing tricks here, and why?
