A world ruled by a democracy where only British subjects can vote for their representative to a chamber, say, the House of Commons. Lords can automatically get a seat in the House of Lords. The leader of the majority in the House of Lords is made Prime Minister, and has ultimate control over the Earth, under only the reigning monarch. The monarch appoints governors or viceroys for each ex-nation, who govern the ex-nation, with a systems of consuls, maharajahs, and a good many other subordinates.
