Was there a “Corbyn effect” on newspaper sales in September as Labour selected the new special one? Not for a Tory-leaning press unleashing salvoes of criticism. The Sun (-3.51%), the Express (-2.88%), the Mail (-1.08%) and the Telegraph (0.50%) were all down on August’s figures, with the Times standing flat pat. As for those readers who said they’d cancel their Guardian or Indy because they weren’t cheerleading for Jezza hard enough, they’re difficult to pick up too. The Guardian (up 1.02%) and the Indy (up 1.73%) had solid Septembers – as, since you ask, did the Observer, up 3.74%.
