Buckingham Palace aides are advising the Queen's guests not to mention Prince Harry and Meghan Markle during their audience with Her Majesty, it is claimed. With the Duke and Duchess of Sussex grabbing headlines around the globe each day, many household guests are keen to discuss the young Royals with the monarch. But flunkies have allegedly begun to clamp down on this popular line of questioning and are informally steering visitors on to more 'polite' conversation topics, it is claimed.
