Prince Charles and Camilla, Duchess of Cornwall remember the late Prince Philip.

Video Transcript

CAMILLA, DUCHESS OF CORNWALL: I saw the way he supported the Queen. Not in a flashy sort of way, but just by doing it quietly, following along behind. It's something that I've learned by watching him.

PRINCE CHARLES: He did make a big difference because it's perhaps more fun than just being totally on your own. And I think my mom did find him a great support, and I think she valued his judgment on some things.

QUEEN ELIZABETH: Seems all right.

ZARA TINDALL: I think the amazing thing that he's been able to do is be an incredible support to my grandmother, but to stay true to himself all the way through. And that's what our grandmother needed, that's why they worked so well together and why they fell in love with each other, I think.
