Princess Diana first challenged Camilla Parker Bowles about her affair with Charles in this exact house… and it’s now up for sale. The events took place at the 40th birthday party of Annabel Elliot in 1989. It was the first time Diana had tackled Camilla about her husband. Palace Confidential’s @Richard Eden has written about it for the Daily Mail. #princessdiana #camilla #royalfamily #kingcharles #royals
