Looking at the Brexit thing...well, yes, it will happen soon and things will just go on, or change, as they normally do to deal with change. People will do this, and do that etc. Nothing very interesting. The UK is not a dynamic or interesting 'thing' to anyone outside it, nor to a lot of people in it. That won't change. Grist for the mill of history. Kingdoms naturally die...it may well be what Kingdoms do best.
