LONDON (AP) — The Princess of Wales canceled plans to attend Royal Ascot on Wednesday as she continues to balance the demands of her public duties against the realities of her recovery from cancer.

Kate Middleton withdrew from attending Royal Ascot, one of the largest events in the British social calendar, with palace officials saying she was attempting to find the "right balance" as she recovers from cancer.

Catherine, Princess of Wales dropped out of a planned engagement at Royal Ascot at short notice on Wednesday. Kate, 43, had been expected to join her husband Prince William as well as King Charles and Queen Camilla at the horse racing event. Racegoers were hoping to see the popular royal during the traditional carriage procession at the racecourse.
