Andrew Windsor’s royal exile shown by Solo Ride as daughters joined Charles

Among the other senior members of The Firm in attendance were Prince William, 43, and Catherine, Princess of Wales, also 43, who returned to the lunch after missing last year’s party while undergoing her cancer treatment.

They were joined by their children Prince George, 12, Princess Charlotte, 10, and Prince Louis, 7.

The presence of the Wales family marked a return to normality after what aides previously described as an exceptionally difficult period.

Other guests included Prince Edward, Duke of Edinburgh and Sophie, Duchess of Edinburgh, along with their daughter Lady Louise Windsor. Anne, Princess Royal, was there with her husband Vice Admiral Sir Tim Laurence, while Prince Edward, Duke of Kent, was also a guest.

David Armstrong-Jones, the Earl of Snowdon, arrived by bicycle, while Lady Gabriella Kingston attended after her husband’s death last year.
