In 15 months, Britain will host a large meeting in London that may sound like it comes from yesterday but in fact belongs to tomorrow.
The meeting will be the gathering of the heads of government of the 52 countries that are member states of the Commonwealth, a club or network of nations largely, although not entirely, left over from the alumni of the former British empire.
In fact, several of the current member states do not come from the British-related origin at all, and several more have expressed interest in joining this interesting grouping.
