The United Kingdom’s Queen Elizabeth II died of old age, according to her death certificate, which has been published by the National Records of Scotland.

At the age of 96, Elizabeth, the British monarch with the longest reign, passed away on September 8 at Balmoral Castle, her vacation residence in the Scottish Highlands.
The certificate, published on Thursday, shows her time of death as 3:10pm (14:10 GMT) (14:10 GMT).
The detail confirms that the queen died as a number of her family – including her grandsons, the new prince of Wales, Prince William, and the duke of Sussex, Prince Harry – were still travelling to Scotland to be with her.
Her son, the now-King Charles III, and daughter, Princess Anne, were at Balmoral as she died. Prior to September 8, they had already been in Scotland for public appearances.
Just after 12:30 p.m. (11:30 gmt) that day, Buckingham Palace issued a statement stating that the queen will continue to be under the care of doctors because doctors were worried about her health. Her death was officially declared at 6:30pm (17:30 GMT) (17:30 GMT).
The queen, who spent 70 years on the throne, had been suffering from what Buckingham Palace had called “episodic mobility problems” since the end of last year, forcing her to withdraw from nearly all her public engagements.
According to the certificate, Princess Anne reported her death on September 16.
Its publication came as hundreds of people lined up on Thursday outside Windsor Castle, as the landmark royal residence and its historic St George’s Chapel, where Elizabeth was buried last week, reopened following the monarch’s death.
