I know The Commonwealth is very much a extreme minority interest area and this rather bizarre grouping of countries is of no international significance but it's very important to the Queen apparently and the royals generally, some in Britain, the DUP and a few African dictators. And from my experience on P.ie one or two on here.
Turns out the 'Head of' position is not an automatic hereditary position and with the Queen coming to the end of her shift, and one wanting Charles, the 'leaders' are meeting in secret to figure out who will be the next head.
