Prince William gave a visible 'barrier gesture' towards his brother Harry at this year's Jubilee celebrations, experts report.
The move has been described as the 'opposite of an acknowledgement' as the warring siblings attended the same event.
The body language expert confirmed her thoughts as the pair attended a service of thanksgiving for the Queen at St Paul's Cathedral.

The event was Harry and wife Meghan Markle's first public appearance at a royal celebration since quitting the monarchy.
Despite coming together at the same event, the pair were seated far apart and were not seen chatting or even standing next to each other, reports the Mirror.
But despite the distance, body language expert Judi James told the Mirror William adopted a "barrier gesture" as he and wife Kate walked past the pew where his brother sat on the way to his seat.
Judi explained: "So far there have been no ‘moments’ between the brothers to signal acknowledgement or a hint of any restoration of their friendship bonding.
"Harry looked firmly resigned to the back row here and was not sitting behind his brother as he was for the last service of remembrance.
"Harry’s expression did suggest some relief as he joked with Zara as he searched for his car on the way out and he threw a wide, open-mouthed grin in her direction from the pews, but otherwise he fell into a haunted eye expression with some rapid blinking to suggest inner anxiety, leaning in and down to Meghan when she spoke as though keen to get some support.
"There was the opposite to an acknowledgement from William as he walked past Harry’s row during the parade out of the service.
"Sucking in his lips and with his chin pulled up in a gesture of resolve he appeared to turn his head in the other direction for a moment, raising his order of service high in a barrier gesture."
Meanwhile, Judi noted that Meghan's appearance was "as perfect as it could have been under difficult circumstances".
She said: "Her posture was upright and her smile was designed for a calm but low-key appearance.
"While Harry’s emotions and behaviour seemed to fluctuate between subdued and anxious and odd moments of fun break-outs that looked like another symptom of inner anxiety or tension, Meghan used a small touch on his back as what looked like the only other PDA than their signature hand clasp."
There has been much made of the rift between William and Harry with their frosty relationship reportedly sparked by William's concerns over Harry's fast-developing relationship with Meghan ahead of their royal wedding in 2018.
The tense row quickly boiled over - with Harry claiming his brother was "trapped" within the royal system during a bombshell interview with Oprah Winfrey after quitting as a senior royal.
Since leaving the UK in early 2020, Harry has only seen his brother twice before the Jubilee celebrations - at the funeral of Prince Philip and at an unveiling of a statue of their late mother Princess Diana.
