Kate, the Princess of Wales, canceled plans to attend the Royal Ascot horse race as she continues her recovery from cancer.

The Princess of Wales has pulled out from a planned attendance at Royal Ascot. Catherine, who is making a gradual return to public life after her cancer diagnosis last year, is trying to find the right balance as she fully returns to public engagements, according to royal sources.

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?
