Prince Harry’s relationship with his father King Charles may not be redeemable after his latest interview, but his late mother would have different thoughts on the matter.

The Duke of Sussex, who appeared in an explosive interview with BBC has reportedly left the monarch “frustrated and upset”, dubbed his verdict on UK security appeal as a classic “institutional stitch-up”.

While many experts shared that the late Queen Elizabeth would have been “horrified” by her grandson’s action, a close friend of Princess Diana revealed her true feelings over son’s actions.

“I think she might have been proud,” royal author Ingrid Seward told Hello!, noting that the late Princess of Wales would have been said, ‘I’m glad you said what you thought.’

“I think she would, I’m guessing, that she might have been quite proud of him for speaking up and saying what he thought, because that’s what she liked,” Seward continued. “She liked to say exactly what she thought and then deal with the consequences afterwards, which is, of course, what happened to her.”
