Dear sionnsar,
I'd never heard that the Archbishop of Canterbury is sixth in line to the succession to the British crown. Is that really true?
From what I can see on the Internet, the Archbishop of Canterbury isn't in the line of succession, at least through the first 50 places or so.

See #4. I'd not heard it either.
