At long last, we finally meet Lady Diana in season 4. What was the age difference between Charles and Diana?
Answer 12 years
Initially, Charles brushed off the age difference. “I think that Diana will keep me young, apart from anything else”, he said at the time of their engagement. The truth was that they barely knew each other — they had met in person only 13 times prior to the wedding. As the show portrays, Charles came to resent Diana's youthfulness and star quality.
