Presenting the prizes at the end of a polo match in Cirencester, the Princess came face to face with her husband. As she handed him his consolation prize, she offered her cheek for a friendly kiss. But Prince Charles clearly thought her deserved more, and in confusion he kissed her firmly on the mouth.
Cheers and whistles came from the crowd, and Diana, by now blushing a deep red, held her hand over her mouth, staring at the ground. But she couldn’t help laughing at what must have been Prince Charles’ most spontaneous public display of affection since their ‘balcony scene’ at their wedding in 1981.
