Thank you, Lumutqueen for the reminder that while Parliament has passed such a law The Succession to the Crown Act 2013 in April 2013, it needs to be approved by the 15 Commonwealth Nations. However, the law is based on principles decided by those Commonwealth nations when meeting in Perth, Australia, in October 2011. Therefore there is little reason to think it won’t be approved. Unless you Brits know something what isn't in the news yet.
You are technically correct, it remains ‘not yet’.
Please forgive my presumptuous American claim, haste, and cheer at such a momentous event in the history of humanity. The welcoming of a possible, female heir to such a famous throne and in my lifetime!
