The ceremony is just one of the formalities which must take place in the days following the death of a monarch and the appointment of a new sovereign.
One of the plans included is that the new King will embark on a UK mourning tour.
So, just where will King Charles III visit, what will he do on his tour, and when will he be undertaking the tour?
Here’s what you need to know.
Where will King Charles III go on his UK mourning tour?
King Charles III will visit all four nations as part of a UK mourning tour.
He will begin in London, as the final preparations for Queen Elizabeth II’s funeral are made, and then travel to Scotland, Northern Ireland and Wales.
What will King Charles III do on his UK mourning tour?
On his visit to each of the four nations, King Charles III will be visiting leaders in the UK.
It is understood that the new King will be starting his tour with a visit to the Scottish parliament and a service at St. Giles Cathedral in Edinburgh.
The day after he begins his tour, King Charles III will arrive in Northern Ireland, where it is expected he’ll receive another motion of condolence at Hillsborough Castle and attend a service at St. Anne’s Cathedral in Belfast.
On the final part of his trip, approximately seven days after the death of the Queen, King Charles III will travel to Wales to receive another motion of condolence at the Welsh parliament and attend a service at Llandaff Cathedral in Cardiff.
When will King Charles III go on his UK mourning tour?
In accordance with Operation London Bridge, the official plans which detail all of the things that will happen following the death of Queen Elizabeth II, the new King is expected to begin his tour three days after his mother’s passing.
This would mean that he would begin his tour on Sunday 11 September.
There have already been some changes to the timescales laid out by Operation London Bridge, however, and the date of King Charles’ tour has not yet been announced.
For example, the meeting of the Accession Council at St. James’ Palace, London, to proclaim King Charles the new sovereign was expected to take place the day after the Queen’s death.
This did not take place until 10am on Saturday 10 September, however, two days after the Queen’s death, as her passing was not announced until 6.30pm on 8 September and there was not enough time for the necessary plans to be made for this to happen the next day.
It is, however, expected that King Charles’ mourning tour will take place between Sunday 11 September and Thursday 15 September, or possibly Monday 12 September and Friday 16 September.
