Britain's Queen Elizabeth dies aged 96 after 70-year reign
"The Queen died peacefully at Balmoral this afternoon," Buckingham Palace said in a statement. "The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
Elizabeth's eldest son Charles, 73, automatically becomes king of the United Kingdom and the head of state of 14 other realms including Australia, Canada and New Zealand. His wife Camilla becomes Queen Consort.
News that the queen's health was deteriorating emerged shortly after midday on Thursday when her doctors said she was under medical supervision, prompting her family to rush to be by her side at her Scottish home, Balmoral.
The queen had been suffering from what Buckingham Palace has called "episodic mobility problems" since the end of last year, forcing her to withdraw from nearly all her public engagements.
