I've got some friends who recently moved up there (from Hertfordshire), and they have said that there is a very strong nationalist (particularly anti-English) sentiment.
For example, in Remembrance Sunday there is a move (I'm not sure whether it's been enacted or not) to get all profits from Poppies to go to just Scottish veterans, as opposed to, say, England, where profits go to any veteran of Britain or the Commonwealth. Also, there's been stuff like 'Safeway for Scotland', and more generally they say that there's just a feeling of superiority, especially over the English.
I realise that it's quite a large generalisation to claim all this just from anecdotal evidence, but it seems to be pretty widespread.
