The Westminster Governments can hardly have been unaware of such concerns. The referendum on Scottish Independence in 1979 required support of more than 40% of the electorate for any Constitutional change to be effected. Sometimes, it seems, the rules might just possibly be modified in a plausibly defensible way, in order to make the result desired by some just that bit more likely.
How fondly I remember our Own Dear Queen intoning how she could not forget that she was crowned Queen "of a United Kingdom", carefully negotiating the requirement to keep apart from politics. At least she didn't say using bleach might keep you safe from the Hielan' Midgies.

Wonder which Tory sycophants will be fast-tracked to "bracket" The Bould Boris. Looks or voice?
