Saturday marks D-Day+1, or D+1, of the plans following Queen Elizabeth II's death with a timeline of events expected to take place today.
The reason Saturday is D+1 despite the Queen passing on Thursday is that the announcement took place in the late evening, so all plans were shifted to a day later to allow more time for complex arrangements to be efficiently carried out.
Here is a breakdown of what you can expect to happen throughout today in the aftermath of the Queen's death.
