Break-up of United Kingdom closer than ever.

[frequent]

I sort of agree - if you mean that any constituent country within the UK could hold their own referendum, with only the people living in that country taking part.

If however you're suggesting that people living outside Scotland should vote in a Scottish independence referendum (or people living outside England should be able to vote on a hypothetical English independence referendum) then I fundamentally disagree. You cannot have one country vetoing another country's self-determination - such a proposition is completely illogical

I guess there's a side issue of whether Scots living outside Scotland should also have a vote. There's a precedent in that ex-pats from various countries can still exercise their vote in their home country elections. Thailand is but one example of that, as is (I believe) Australia

It's not the same frequent. A citizen of a nation state is easily verifiable and therefore can be allotted a vote. This is not the case with England, Scotland, Wales or Northern Ireland.

Anyway, the point is moot. There won't be another referendum this century..
