Why Prince Louis Left in the Middle of King Charles III's Coronation

etonline.com:

Prince Louis needed a break. Following much speculation regarding whether the 5-year-old royalwould attend the coronation of his grandfather, King Charles III, on Saturday, Louis looked to be on his best behavior as he arrived at Westminster Abbey with his sister, Princess Charlotte, and parents, Prince William and Kate Middleton.

Louis entered the Abbey in procession with his family, while his older brother, Prince George, played a key role elsewhere as a page to the king.

At one point, Louis was seen adorably holding hands with Charlotte. Later, he appeared to become restless in his seat while his mother whispered in his ear.

He was also notably photographed letting out a big, hilariously unapologetic yawn. The prince ended up leaving midway through the historic ceremony, with viewers noticing his absence as cameras panned to his parents and sister while the congregation sang «Praise Him.» ET has learned that Louis' early exit was all part of a plan by the palace, and that he was expected to process into the Abbey with his parents and retire before the completion of the service.
