With Valentine’s Day upon us, one body language expert has deemed King Charles and Queen Camilla as the most compatible royal couple.

Speaking of the couple on behalf of Betfair Casino, body language expert Darren Stanton shares that he believes the pair’s “deep intensity” has continued to grow throughout their romance.

He said: “I would say Charles and Camilla are the most compatible Royal couple. They have had this deep love since they were both very young. We’re talking about a 50-year-plus romance.

“They’ve been in love a long time and it’s been an intense relationship where they’ve had to overcome a lot.

“Even looking at pictures of them when they were younger, whenever Camilla was photographed, it’s so clear they had this deep intensity for one another and it has continued to grow.”

Speaking further about the couple, who have been married since April 2005, the expert added: “They have the same passion for each other still to this day.

“During public events, Charles is often looking around and fidgeting when Camilla isn’t by his side, which shows how dependent he is on her. But when they are together, we see this genuine laughter shared between them with engaged eye contact, and this shows how they are on the same page emotionally. “

Speaking of how the Queen has impacted her husband, he added: “When he was a young Prince, we rarely saw him display a relaxed nature.

“Camilla brings that side out of him where he can be himself, let go and just enjoy his time as King.”

Mr Stanton also spoke of Zara and Mike Tindall, who have been married since July 2011.

Speaking of their relationship, which began in 2003, he said: “I think the public are intrigued by Mike and Zara – and that is purely down to how they come across during events and engagements. They really enjoy each other’s company, and there’s a strong level of trust between them.

“You can tell they treat each other well and stick up for each other when times get hard. They have a really natural rapport and a deep connection.”
