The princess was reportedly having dinner with her Norfolk neighbours, the Marquess and Marchioness of Cholmondeley, David and Rose, at their home, the rather grand Houghton Hall. Their estate covers 1,000 acres and at the time the Houghton Festival was taking place on their grounds. A source told the Daily Mail: “After dinner, one of the guests suggested that Catherine go to the festival. “Catherine was nervous about the idea, but, after much discussion with her protection officers, she went with lots of security. William wasn't there.” #britishroyalfamily #princesadegales #catherineprincesadegales #rosehanbury
