Prince William and Kate Middleton will be king and queen one day, but their former private secretary Jamie Lowther-Pinkerton tells People the pair are thoroughly prepared for what's to come.
The Duke and Duchess of Cambridge, who dated for several years before marrying in 2011, celebrated 10 years together in April.
How is the couple shaping the monarchy, though, now that they're the face of the next generation of royals, following Prince Harry and Meghan Markle's decision to exit the firm? Lowther-Pinkerton says by focussing on issues the royal family hasn't touched on much before, including mental health, early childhood development and climate change.
The royals have since started their own YouTube channel too, taking a different approach in connecting with people.
"They are bringing to the party different means of achieving the whole," he explains. "He [William] has the experience of knowing where the institution sits and seeing it evolve. The duchess brings this pragmatic awareness of what it's like to be from a decent, down-to-earth family."
He adds: "They have a solid bond through these last 10 years. If you had scoured the realm you couldn't have got a better pair, frankly."
