King Charles III led the royal family as they walked behind the coffin, draped with a Royal Standard, adorned with the Imperial State Crown and pulled on a gun carriage of The King’s Troop Royal Horse Artillery.

The new monarch walked in line with the Princess Royal, the Duke of York and the Earl of Wessex.

Behind the King were the Queen’s grandsons in a line – Peter Phillips, the Duke of Sussex and the Prince of Wales – who were followed by the late monarch’s son-in-law Vice Admiral Sir Tim Laurence, the Duke of Gloucester, the Queen’s cousin, and her nephew the Earl of Snowdown.
