On the day of Queen Elizabeth II's state funeral, a committal service will take place at St George's Chapel as a way to symbolise the end of her reign.

Millions of people from around the world watched the funeral service earlier today (Monday, September 19) to bid a final farewell to the late monarch.

The Queen passed away peacefully at Balmoral on Thursday, September 8 sparking a period of national mourning.

Following a procession and the Queen's coffin being driven on a route the committal servicd will take place at 4pm.

Around 800 people are expected to attend including the King, the royal family, realm prime ministers, governors-general and mourners from the Queen’s household past and present.

There are several traditions associated with this service to mark the end of a monarch's reign.

Queen Elizabeth II committal service traditions

As part of the service the Imperial State Crown, the orb and the sceptre will be lifted from the Queen's coffin and placed on the High Altar.

At the end of the last hymn, the King will step forward and place the Grenadier Guards’ Queen’s Company Camp Colour – a smaller version of the Royal Standard of the Regiment – on the coffin.

Only one Royal Standard of the Regiment is presented during a monarch’s reign, and it served as the Queen’s Company Colour throughout her lifetime.

At the same time former MI5 spy chief Baron Parker, who is the Lord Chamberlain in the Queen's royal household, will “break” his Wand of Office and place it on the coffin.

This ceremonial breaking of a white staff signifies the end of his service to the Queen as sovereign.

As the coffin is lowered into the royal vault, the dean will say a psalm and the commendation before the Garter King of Arms pronounces the many styles and titles of the Queen.

The Sovereign’s Piper will play a lament from the doorway between the chapel and the Dean’s Cloister and walk slowly away so the music gradually fades.

The Archbishop of Canterbury will pronounce the blessing, and God Save The King will be sung.

After this members of the royal family will depart, but will then return later in the evening for the burial service.
