I’m putting this up not so much for the show itself…
…but to note that the devolution of power from the Crown to Parliament is an interesting story, full of exceptions, curiosities, and at least three big, gaping holes that could theoretically allow an ambitious monarch to take over the whole thing and actually become the ruler of Great Britain. I don’t think that that will happen any time soon, mind you. But a lot of Parliamentary supremacy is based on convention, and not actual law.
The whole thing would make for a pretty good technothriller, in fact. Especially if the Crown won in the end. That’d be a twist.
