Elizabeth II one of just six British queens regnant [audio 8min]

Queen Elizabeth went to Westminster Wednesday morning for the State opening of Parliament. She went there as only the 6th woman in British history to have been crowned and anointed Queen. Traditionally, society has treated men as the natural rulers, but 6 women in history have reigned in Britain in their own right. How did these 6 manage to confront the sceptics and balance society’s traditional roles for women -- of wife and mother, with the responsibilities of a monarch? Presenter Jenni Murray talks to Maureen Waller, author of the new book Sovereign Ladies: The Six Reigning Queens of England (John Murray).
