Here is the timeline of events that are expected to take place today following the death of Queen Elizabeth II.

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 – meaning plans have been shifted a day to allow the complex arrangements to be put in place, meaning D+0 will be considered Friday.
