After Kate Middleton's name appeared on the carriage procession list at Royal Ascot, a corrected list was issued that showed the Princess of Wales wasn't attending the event. What happened behind the scenes?

The last-minute nature of the cancellation made Charles look weak and disrespected, but, suffering from cancer himself, he gets it, sources say.

Kate, who shares three young children with William, has made a gradual return to public engagements this year since announcing in January that she is in remission from cancer. Kate has not shared details of the type of cancer with which she was diagnosed, though she has shared she underwent chemotherapy treatment.
