I now call in support of my contention a recent opinion poll about Scottish independence - conducted in England and Wales:
Compare this with England and Wales. English and Welsh respondents are pretty evenly split on Scottish independence – 41% would support Scotland becoming independent, 40% would oppose it (meaning, of course, that Scottish independence is actually somewhat more popular with the English and Welsh than with the Scots). Perceptions amongst the English & Welsh are that Scotland currently gets the better deal from the Union – 54% think Scotland benefits more, compared to 27% who think it is equal and 8% who think England and Wales get the better deal.
The Scots - for all their flirtation with the world's smuggest political leader - seem to think they get a pretty good deal from the UK's constitutional settlement (which of course they do). So why change it? Us English, on the other hand reckon we get a lousy deal! And, if the solution is to dump Scotland, then we'll dump Scotland.
