Operation London Bridge: What to expect in the days leading up to Queen Elizabeth II's funeral
London — The U.K. government has had a detailed plan for what happens after the death of Queen Elizabeth II prepared for many years. Codenamed Operation London Bridge, with a long list of sub-operations laying out plans for the individual components of the plan, it was a closely guarded secret.
After the queen's death on Thursday, plans were reported widely by British media. Below is what we may roughly expect to see in the 10 days between Queen Elizabeth II's passing and her state funeral, with the caveat that none of the plans are set in stone until confirmed by Buckingham Palace, and that may shift:
After the queen passes away
The day of Queen Elizabeth II's death is referred to as D-Day or D+0, in the government plan for the aftermath of her passing. Because the announcement of her death came so late on Thursday, however, around 6:30 p.m. local time, the schedule was shifted, so D-Day was pushed to Friday, according to Britain's PA news agency.
On Friday, King Charles III and his wife Camilla, now the Queen Consort, will return to London.
The bells of Windsor Castle, Westminster Abbey, and St. Paul's Cathedral are set to toll, and there will be gun salutes, with one round fired for every year of the queen's life, at London's Hyde Park and the Tower of London.

Britain's House of Commons is expected to convene at noon local time Friday for Members of Parliament to pay tribute to the queen in an extraordinary session set to last 10 hours.
