Having read through this entire thread in one go - as an American author advised we should do, and he noted for his horrific imaginings - I found many facts and opinions of interest, two of which I think might bear a little more "input".

First, punkfolkrocker posted "France's Brexit song", in which, as Hugh MacDiarmid observed nearly a century ago, the singers "use 'England' when the UK's meant". Lord Goold, once a high-ranking Conservative Minister, once said that the Tories wouldn't bother about demands for Independence in Scotland until people were smashing windows in Sauchiehall Street (and anyone adding, "you mean every Saturday night?" runs the risk of being "called out" for stereotyping...).

Secondly, re. "electability" (Labour Party & its leader), bearing in mind the power of the Press &c., as instanced several times above. What does this actually mean? A leader and a party deemed acceptable by whom? Just setting a perr o' mappys jinkan.
