What you describe was the role of the right-wing tabloids (which is almost all of them), and, as you say, not the only cause of his demise. The other major factor was the role of his right-wing enemy within, the Ruth Smeeths, the John Manns, the Margaret Hodges, to name but a few, who would do and say anything, including throwing an election, to get rid of him and install one of their own. And look where that's got us. Starmer. We'd have been ten times better off leaving Jeremy in place. At least he would have got his teeth into Johnson. Well, unless you've got a better bloody idea.
