That fact received widespread press coverage and drew attention to the Act of Settlement's bar on Catholics ascending to the throne, and prompted calls in both Canada and the United Kingdom for the respective prime ministers to consider the issue.
She did not give up her Canadian citizenship.
Some reported unease was caused in royal circles when Kelly and Phillips were interviewed and photographed by Hello! magazine, for a reported fee of £500,000.
