Yeah, the English have a habit of changing when they somebody is British or not. It was the same with George Best. When he was alive he was drunken scumbag from backwater Northern Ireland, but when he died he was suddenly the greatest British footballer ever and would be sadly missed most by the fans of Manchester United. Another thing that seriously annoys me is how a number of war songs always talk of how England defeated the Axis. Without Harland and Wolff and Shorts Aircraft company, Britain would have been duck. After London, Belfast was the worst bombed city in Britain. It's nice to feel appreciated.

That said, it's not all big, bad England. Some Scots and, to a lesser extent, Welsh want to have their cake and eat it (I don't include Northern Ireland in this one, for things are little bit different there). Via the Barnett Formula, for example, the Scots have been getting a fair amount of extra money spent on them per person, so they've done very well out of the Union, so have very little reason to complain.
It's true that in the last couple of years, Scottish and Welsh nationalism has reawakened, and there is, of course, some historic rivalry between Scotland and England in particular, but there is not the groundswell of opinion to see the Union disintegrate and some of those has been down to the failures of the current Labour regime and carpet-bagging by nationalist parties. The truth is that the vast, vast majority of Scots and Welsh support the Union, but, at the same time, they would just like the English to zip it with their slightly patronising, arrogant songs, views etc.. The topic doesn't come up that often in conversation either. At Glasgow University, I meet people from all over the country and we get on very well and have plenty of banter about our identities within Britain.
This is not the first time that D.D. has had something sly to say about the Union. With all due respect, you don't seem to have a good grasp about the situation over here, so rather than criticise it with limited knowledge, it would be better to inquire about it. So, to conclude, there are a couple of things each part of the Union likes to gripe about, but it's not that serious. It would be wise not to listen to hypocritical radicals such as Connery.
