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.

The princess canceled plans to attend the horse racing event on Wednesday as she tries to find the “right balance” in her recovery from cancer, Kensington Palace said.
