A body language expert has claimed the Princess of Wales made "a gesture of polite concern" to an anxious Queen Consort Camilla at the Remembrance Sunday service yesterday.
The pair were part of the group who stood on the balcony of the Foreign Office, overlooking the Cenotaph, where wreaths were laid by King Charles and other royals to honour the nation's war dead.
It was the first Remembrance Day held since the death of the Queen - an empty space on the balcony marking where the late monarch had stood in previous years when Charles would lay a wreath on her behalf, reports the Mirror.
Judi James, a body language expert, said the experience was a tense one for Camilla during her first service as Queen - but with the Princess of Wales by her side to keep her calm.
She told the Mirror: "Watching from the balcony Camilla combined signals of regal duty with some rituals of anxiety.
"Standing beside Kate, she performed a subtle smile of acknowledgement as her wreath was laid and as she turned to Kate on their way from the balcony she threw a rather fond smile as Kate spoke to her.
"Camilla smiled at Kate for a second time before nodding, again in a gesture of acknowledgement as she walked ahead of Kate in her new role of Queen.
"Otherwise though there were gestures of open anxiety from Camilla. She looked unable to keep totally still and spoke to Kate at one point but while looking straight ahead rather than turning to her.
"Kate turned her head quickly in a gesture of polite concern. Kate’s calm and very still body language was in contrast to Camilla’s nervous movements that showed the most in the fluttering of her hymn sheet as her two hands fiddled with it throughout."
She added: "Charles stood at the Cenotaph as though totally alone and lost in his thoughts. His mouth was pulled down at the corners and his rapid blinking hinted he was close to tears as he remembered his mother as well as those fallen in action.
"There was even a micro-gesture of a small spasm of the lips to show suppressed emotions as they played the Last Post."
Remembrance Sunday was one of the most significant and important engagements in the royal calendar for the Queen, who died nine weeks ago.
The late monarch was a teenager during the Second World War, and only missed seven Cenotaph services during her reign.
