Jim McLean:
Why "Elizabeth I of England"? The programme title makes no attempt to state where she's queen of.
If you wish to be picky, surely the title should be "Queen Elizabeth" as the clarifier "the first" only tends to be added once there is a later sovereign of the same name.
It is even debatable whether the current monarch should be styled Queen Elizabeth the second (first of Scotland) as the late Queen Mother was also officially:Her Majesty, Queen Elizabeth, the Queen Mother Here
