Of all the members in the British Royal Family, the relationship between Prince Philip and Prince Charles is probably the least speculated upon.
But the father-son relationship between Prince Philip and his eldest son Prince Charles is actually thought to be extremely fraught at times.
Watch the trailer for The Crown season four. Post continues below.
Prince Charles has described his father as "harsh" and "hectoring" in the past and Philip has acknowledged the fact they are polar opposites, telling royal biographer Gyles Brandreth in 2016 that Charles is "a romantic, and I’m a pragmatist. That means we do see things differently. And because I don’t see things as a romantic would, I’m unfeeling."
Royal correspondents believe the relationship is flawed, in part, because Prince Philip wasn’t around for Prince Charles at an early age.
