Prince William steadfastly refused to make eye contact with his younger brother Prince Harry during the Queen's Thanksgiving Service.
There was no obvious interaction shown on the camera between Harry and his brother William, who have long faced a rift, and they sat apart during the service at St Paul's Cathedral on Thursday.
The Duke and Duchess of Sussex returned to the royal fold for the celebrations but sat in the second row, behind the Countess of Wessex and the Duke and Duchess of Gloucester.
