King Charles kept his cool while Queen Consort Camilla showed wariness and fear after they were pelted with eggs during a walkabout, a body language expert has claimed.
The royal couple were being welcomed by city leaders in York today when four eggs were hurled at them, all of which missed before the pair were ushered away.
The lone protester was heard shouting "this country was built on the blood of slaves" as he was wrestled to the ground by several police officers at Micklegate Bar, a medieval gateway and focus for grand events before being arrested.
Onlookers in the crowd started chanting "God save the King" and "shame on you" at the man.
The monarch continued shaking hands as the eggs flew in his direction, pausing briefly to look at the shells cracked on the ground as Camilla followed behind him.
But despite appearing calm, body language expert Judi James says the Queen Consort gave away her fear with one signal.
Judi told the Mirror: "Charles has already shown his credentials as a man who keeps his cool under even extreme attack as he once brushed off an on-stage rush by a gunman with the body language signals of nothing more than a calm determination to get on with the job.
"This pelting by eggs brings out a similar amount of cool from the King as well, it has to be said.
"Camilla however does react and her body language suggests wariness that extends to actual fear.
"Her mouth stretches and dips at the corner and she keeps glancing backwards as though scared of more missiles.
"The noise the crowd are making seems to be cries of support but they blend to make a rather frightening screeching noise."
And Judi wondered if Camilla's previous public perception played a part in how she reacted today.
She added: "I wonder whether this event triggers the Imposter Syndrome in Camilla especially. It occurred in York, which should be full of royal fans, and it has happened just as she has taken over the role of Queen.
"This was a controversial upgrade and although the couple used stealth and the advantage of time to re-brand Camilla to grow her popularity and gradual acceptance from the public, the ghost of those early years after Diana died must still haunt her, making her especially vulnerable to any criticism or ‘attacks’ like this."
The suspect was later carried away in handcuffs, with his legs bound by two uniformed officers who put him in the back of a police van.
Charles and Camilla have been visiting Yorkshire to carry out a number of engagements.
They were in York to unveil a statue of the late Queen Elizabeth II, the first to be installed since her death.
Speaking at the ceremony, Charles said: "The late Queen was always vigilant for the welfare of her people during her life.
"Now her image will watch over what will become Queen Elizabeth Square for centuries to come."
The two-metre sculpture weighing 1.1 tonnes and made from lepine limestone from France was designed to celebrate the late Queen's platinum jubilee and was completed in August, the month before her death.
