Years before criticizing Charles for his parenting style, Prince Harry commended his father for ensuring that him and William were “protected” following Diana’s death.

One expert noted the “remarkable” change in tone from the Duke of Sussex’s prior praise of the Prince of Wales. Royal author Robert Jobson shared a statement from a 2017 BBC programme in which Harry paid respect to his father on Twitter.

When their mother, Princess Diana, died, the Duke stated Charles was present for him and Prince William and “tried to do his best”

However, in his new show, The Me You Can’t See, Harry accuses the royals of “total neglect” for his mental health issues.

He further alleged that when his mother died in 1997, Charles made him “suffer” by failing to “make it right” for him.

“Yes, a remarkable change in Harry’s attitude,” royal commentator Richard Eden said in response to Mr Jobson’s post.

“Harry is unrecognisable from the man he was,” Angela Levin, the Duk’s biographer, remarked. “Tragic.”

Harry, who has since retired from royal responsibilities and gone to California with Meghan Markle, complimented Charles in the BBC documentary Diana, 7 Days, just four years ago.

“How you deal with that, I don’t know.

“But he was there for us. He was the one out of two left. And he tried to do his best and to make sure that we were protected and looked after.

“But he was going through the same grieving process as well.”

In a series of recent interviews, Harry has altered his tune and struck out at his father.

The Duke chastised Charles for expecting his sons to bear the demands of royal life in his new documentary series on mental health with Oprah Winfrey.

“My father used to say to me when I was younger, he used to say to both William and I, ‘Well it was like that like that for me so it’s going to be like that for you’,” he explained.

“That doesn’t make sense.

“Just because you suffered doesn’t mean that your kids have to suffer, in fact quite the opposite – if you suffered, do everything you can to make sure that whatever negative experiences you had, that you can make it right for your kids.”

He had previously said no child should have to walk in their mother’s funeral procession, but told filmmakers: “Before I knew it I found myself with a suit on, with a black tie and white shirt, and I was part of it.

“Generally, I don’t have an opinion on whether that was right or wrong. I’m glad I was part of it. Looking back on it now, I’m very glad I was part of it.”

And now, he says he went through a “nightmare” between the ages of 28 and 32, numbing his anguish with alcohol and narcotics.

“I was willing to drink, I was willing to take drugs, I was willing to try and do the things that made me feel less like I was feeling,” he explained.

“And I would find myself drinking, not because I was enjoying it but because I was trying to mask something.”
