Royals arrive at Westminster Abbey for coronation rehearsal

King Charles arrived at Westminster Abbey with the Prince and Princess of Wales and their children today for a coronation run-through.

With three days to go until the historic event, Charles was pictured beaming outside the abbey in central London as he arrived with William, Kate and their children - Prince George, nine, Charlotte, eight, and Louis, five.

Future king George, nine, will be one of his grandfather’s pages of honour and is expected to be tasked with holding the train of Charles’s regal robes.

William will kneel before his father and vow to be his “liege man of life and limb” in the only homage of royal blood of the ceremony.

He will also help clothe the King in his golden robe royal, also known as the mantle, ahead of his crowning.

The royals were also joined by Prime Minister Rishi Sunak, who will recite a Bible verse during the ceremony.

Rehearsals for the official procession were under way last night, as thousands of military personnel marched from Buckingham Palace to the Abbey in the early hours of this morning.

Crowds gathered in St James' Park to view the procession rehearsals.

Soldiers carried instruments including saxophones, trumpets, horns and cymbals as they marched back down the Mall after 3am.

The Gold State Coach was also spotted passing Buckingham Palace shortly after 3.20am.

Several royal 'superfans' have already set up camp along the procession route, with massive crowds expected throughout central London on Saturday.
