'Stiff upper lip:' UK prepares for 10 days of mourning following Queen Elizabeth's death | LiveNOW from FOX

Queen Elizabeth II is being mourned by her family, fans and admirers. In Britain, her death at age 96 has thrown a state apparatus into motion that has sat idle for 70 years — since Elizabeth's father, King George VI, died in 1952. The British government dubbed the intricate protocol of handling Elizabeth's death "Operation London Bridge." It ranges from succession rules to the process of bringing the queen's coffin from Balmoral Castle in Scotland to London. The London Bridge plans were leaked to Politico last fall. Some of the details may have changed since then — but using them as a guide, here's a brief look at what the documents say will happen in the first 10 days after the end of the queen's record-setting reign: Day Zero starts with the royal household notifies the public of the queen's death. Prince Charles immediately succeeds to the throne upon his mother's death. He will be known as King Charles III. His wife, Camilla, becomes queen consort. The couple stay at Balmoral overnight. Day Ten finishes with a state funeral service is held at Westminster Abbey, triggering an observance of two minutes' silence in the U.K. After a final service in St. George's Chapel at Windsor Castle, the queen is buried on the castle grounds next to her husband, Prince Philip, who died in April 2021.
