Interesting Royal fact: If Edward VIII had not abdicated, but everything else had remained the same, The Duke of Gloucester (currently running 18th in the line of succession) would now be King. Such is the fickle hand of fate.
I don't suppose it matters much. Do we really care what kind of person our Monarch is, provided they remain dignified and impartial? In which case, The Duke of Gloucester would have fitted the bill perfectly well.
