Kate Middleton offered a "warm" gesture to "appease" Camilla during the King's Coronation, according to a body language expert.
The Royal Family were filmed curtsying and bowing to new monarch King Charles and the Queen as they arrived for the special concert at Windsor on May 6.
However, the Princess of Wales made a point of specifically curtseying to her mother-in-law while others didn't, according to Judi James.
