The UK is in an official period of national mourning following the death of Queen Elizabeth II on Thursday.
Here is the day-by-day account of what is expected to happen next, leading up to the Queen's funeral in around 10 days' time. Thursday would traditionally have been D-Day or D+0 in the plans for the aftermath of the Queen's death, codenamed London Bridge.
But the announcement came late in the day - at around 6.30pm on Thursday, September 8 - meaning plans have been shifted a day to allow the complex arrangements to be put in place, meaning D Day was considered to be Friday.
