King Charles and Queen Camilla were joined by Prince William and Kate, the Princess of Wales, Princess Anne and the Duke and Duchess of Gloucester for the event at Westminster Abbey.

The Princess of Wales joined members of the royal family at Westminster Abbey on Monday, March 10, to celebrate Commonwealth Day. As part of the service, Kate and Prince William processed behind King Charles and Queen Camilla. They were followed by Anne, Princess Royal, as well as the Duke and Duchess of Gloucester.

Last year, Princess Kate and King Charles did not attend the key royal event after they were diagnosed with cancer. The Palace announced that Charles had been diagnosed with a form of cancer back in February last year, while Kate went public with her diagnosis in a personal video message shared in March.
