I was fascinated by a programme on Channel 4 last night called "Britain's Real Monarch". Basically, it claimed that England's King Edward IV was illegitimate, and therefore every monarch since then was not the rightful ruler.
The programme went further and traced the "correct" Plantagenet line down to the present day to determine who should have been Britain's monarch, finding one Michael Hastings - who had emigrated to Australia in the 1960s and appeared to be the archetypal "fair dinkum" Aussie bloke.
This could-have-been King Michael I came over as an extremely likeable person and maybe he would have made a good monarch. Ironically, though, he's a republican !
