King Charles III was formally proclaimed monarch at a historic Accession Council on 10 September, ahead of the Queen’s funeral.

However, it is tradition to wait a sufficient amount of time to mourn before a new monarch is crowned.

A date has not yet been announced officially, but The Telegraph has reported that the coronation is likely to be in “spring or summer of next year”.

Here’s what you need to know.

The Imperial State Crown is a worn by the monarch as they leave Westminster Abbey after the coronation.

It is also the crown that has been sitting on the Queen’s coffin during the lying-in-state and throughout the state funeral.

It was made for the coronation of King George VI, the Queen’s father, in 1937, replacing the crown made for Queen Victoria in 1838.

The crown is made of gold and set with 2,868 diamonds, 269 pearls, 17 sapphires, 11 emeralds, and four rubies.

It contains some of the most famous jewels in the collection – the Black Prince’s Ruby, the Stuart Sapphire, and the Cullinan II diamond.

St Edward’s Sapphire, set in the centre of the topmost cross, is said to have been worn in a ring by St Edward the Confessor and discovered in his tomb in 1163.

The crown played a part in the Queen’s Committal Service, which started at 4pm in St George’s Chapel, Windsor Castle, several hours after the state funeral at Westminster Abbey, conducted by David Conner, the Dean of Windsor, and attended by a congregation of 800 guests.

These included the King, the Royal Family, realm prime ministers, governors-general and mourners from the Queen’s household past and present, including personal staff from across her private estates.

During the service, the Imperial State Crown, the Orb and the Sceptre were lifted from the Queen’s coffin by the Crown Jeweller, separating the Queen from her crown for the final time.

The coronation ceremony is a long, intricate process steeped in tradition. Senior members of the Government and the Church of England will attend, alongside the Prime Minister and other leading members of the Commonwealth.

The ceremony will be conducted by the Archbishop of Canterbury, the Most Rev Justin Welby and has remained relatively unchanged for more than 1,000 years. It will take place in London’s Westminster Abbey, as it has for the past 900 years.

The Archbishop will first confirm Charles’s acceptance of becoming King by reading the coronation oath.

Charles will be asked if he will govern the United Kingdom and other nations of the Commonwealth, if he will do so with law and justice, and if he will maintain Christianity in the nation.

King Charles, seated in the Coronation Chair – known as Edward’s Chair – will hold the sovereign’s sceptre and rod, to represent control of the nation, and the sovereign’s orb, to represent the Christian world.

Charles will be anointed, blessed and consecrated by the Archbishop, who will then place the crown of St Edward on Charles’s head.
