The same sort of arguments are playing out in the US, albeit on a shorter timescale. I couldn't say when it started, but it's extremely depressing that the history section in most general bookstores is just a locus for narrative warfare rather than scholarship.
Of course, this phenomenon is by no means unique to these two countries. I know a Japanese author who has a small but dedicated following for his argument that nuclear weapons don't exist: https://books.google.com/books/about/Death_Object.html?id=Mw...
I get what you mean that pop hist. books aren't academic, but "narrative warfare" describes a huge proportion of historical scholarship. Whether or not you agree with it, that's the whole point of Metahistory and the linguistic turn.
