Mike and Zara Tindall are getting "more involved" in the Royal Family due to their similarities to Prince and Princess of Wales.
Darren Stanton, a body language expert, has dissected how the compatibility of royal couples has changed over the years. With Zara and Mike, the daughter and son-in-law to Anne, Princess Royal, Darren says they have a "natural" and "strong" connection, which allows them to "never take themselves too seriously".
Darren said: “Mike and Zara are very similar to William and Kate. I can tell there is a lot of humour, banter and sarcasm. They don't take themselves too seriously and always appear to have a laugh with each other.
"We often see them putting on a strong front wherever they go, but they never fail to have fun. They have definitely become more and more involved in the Royal family and there is a lot more interest about them as a couple.
“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.”

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."
The body language expert also commented on Prince Charles and Queen Camilla (Getty Images)He continued: "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. 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.”
