Nationality is, at times, a very sore point in the UK.
The Scots and the Welsh now have their own Parliaments with MPs (Members of Parliament - like your senators) voted for by people living in their constituencies. I think the same applies in Northern Ireland, but I think they've had their local Parliament probably since 1922 when Ireland was split into Northern Ireland, which acknowledges the Queen as head of state, and Southern Ireland (Eire/Republic of Ireland) with its own head of government. See first couple of paragraphs of

Meanwhile the only people not to have their own parliament are the English. We're ruled by the House of Commons which consists of MPs from England, Wales, Scotland and Northern Ireland.
In sport, Scotland and to a degree Wales, get very upset when someone like Chris Hoy wins a gold medal in the Olympics which is included in the tally for the UK. They think they should compete as separate nations. Commentators add fuel to the fire when they describe Chris as 'British' instead of Scottish.
In the Olympics football, Ryan Giggs who's Welsh, played such a dreadful game that English fans were outraged that such a mardy-bum should have been allowed to play for the British team as there were plenty of Englishmen who would have willingly played for the nation.
Happy families.
