I remember reading that, apart from the fact that both of the Radziwlls had previously been married and divorced, Lee's first husband, Michael Canfield, was widely believed to be the son of Edward, Duke of Kent and Kiki Preston, "the girl with the silver syringe", which might have made things interesting. The Queen is also said to have refused to allow the Radziwills to attend under their Polish titles, which, British protocol notwithstanding, I've always thought rather petty, if true.
