Elizabeth II, Queen of the United Kingdom and other Commonwealth realms, died on 8 September 2022 at Balmoral Castle in Scotland, at the age of 96. Elizabeth's reign of 70 years and 214 days is the longest of any British monarch. She was immediately succeeded by her eldest child, Charles III. Elizabeth's death set in motion the final version of Operation London Bridge, a funeral plan first devised in the 1960s, and Operation Unicorn, the plan for the Queen's death in Scotland. Elizabeth's coffin lay at rest in St Giles' Cathedral in Edinburgh from 12 to 13 September, after which it was flown to London, where it lay in state in Westminster Hall from 14 to 19 September. An estimated 33,000 people filed past the Queen's coffin in Edinburgh, and approximately 250,000 people queued to pay their respects in London. The United Kingdom observed a national mourning period of 10 days.
