Very true, and I think the fact that traditional Britishness exists now more in the regions has had the effect of leaving many feeling of the regional British feeling betrayed and sold out by London.
Indeed, although remember there are different connotations that come with different understandings of Britishness, both historically and in the present. The sense of Britishness associated with the rise of the welfare state was one aspect that played a big role in helping Scottish Catholics integrate into the British state. Also, as I understand things, in England, Britishness is seen as the more tolerant form of patriotism, due to it's idea of including the various peoples of Britain (as opposed to English nationalism which has been quite heavily associated with far-right views and racism etc)
