Princess Kate and Prince William have embraced a "fresh start" following the future Queen's cancer treatment, with their recent trip to the Isle of Mull showcasing their renewed affection and strength as a couple.

However, Harrold said he's noticed one area in which Prince William differs quite a bit from his grandmother. "The late Queen always used to say that she put monarchy over family," he said. "Admittedly she did occasionally put family first in ways that contradict this, but she did say it often. I think William is very different."
