Queen Elizabeth II and Prince Philip are totally disengaged in one photo.

According to North Carolina-based body language expert Bianca Cobb, there were moments when the Queen and the Duke of Edinburgh looked detached.

During their wedding, the couple proved that their connection was solid. However, something happened in the four years before they shared a photo with their children, Prince Charles and Princess Anne.

“When you position a child between your body and your partner's, you create physical distance that could be rooted in a psychological desire for space,” she said.

Things deteriorated further between the couple when they made a royal visit to Malta in November 1967.

“They're totally disengaged — I get the impression something's off,” the expert continued.

“It's like she's using him as a hand rest — it's not intimate at all.”

Despite their friction, Queen Elizabeth II and Prince Philip remain together. According to royal correspondent Camilla Tominey, the pair is “very, very well matched.” Prince Philip is the only person who can categorically tell the Queen if something is not going well.

Tominey pointed out that Queen Elizabeth II has been surrounded with “yes” men, so having someone like her husband who tells her what he thinks of what she is doing is a refreshing change for the monarch.

Queen Elizabeth II and Prince Philip’s relationship is different behind closed doors. The Duke of Edinburgh supports his wife in public, but he is the boss in their household.

At present, Queen Elizabeth II and Prince Philip no longer live together, but their communication is intact. According to Charlie Proctor, editor of Royal Central, the couple lives miles apart.

Prince Philip spends most of his time between Wood Farm on the Sandringham Estate and Windsor Castle. He rarely spends time with Queen Elizabeth II at Buckingham Palace.

However, the Queen is supportive of her husband’s choice. She knows that if he stays in the center for royal life, he would feel obliged to get involved in their engagements. Allowing Prince Philip to be away from the public’s prying eye is the “proper retirement” he earned.
