Although Anne and the Captain were very much in love when they first met, according to Express.com the pair were 'very different people', which subsequently led Charles to dub his sister's spouse - rather cruelly - 'dense'.
Speaking on Channel 5’s “The Royal Family: Affairs and Infidelities" editor of Majesty magazine Ingrid Seward explained: “Mark Phillips is a very good looking man, he looked like an Adonis on a horse, and Anne fell in love with him.
“But I don’t really know that Anne really had that much in common with her husband."
Seward conituned: “[She was] much brighter than him, much quicker-witted than him.
“He was lovely when he was on a horse, but probably a bit dull when he wasn’t.”
