“I don’t know what’s more disgusting Harry’s comment about his father’s health or his suggestion that people want him dead,” the friend said.

In the interview with the BBC, Harry claimed he did not know “how much longer” his father had following his cancer diagnosis.

He also suggested that those who “wish [him] harm” would view his recent legal defeat over UK security as a “huge win”.

The friend added: “It’s very sad, but we all know that he doesn’t want to hear things he disagrees with.”

Earlier this week, Prince Harry’s actions against the Royal Family were branded “unforgivable” by a former friend of the Duke of Sussex.

Ben Goldsmith, who was once close to Harry, condemned his attacks on the royals.

He told the Mail: “Tragic but true Prince Harry’s behaviour is unforgivable.”

The criticism comes after Prince Harry admitted he fears some royals will never forgive him amid his ongoing feud with Princess Kate and Prince William.

Harry took public swipes at senior royals including Princess Kate, Prince William and Queen Camilla in his 2023 autobiography “Spare”.

Since the release of the book, the Prince and Princess of Wales have cut contact with Harry.

The Duke acknowledged the lasting impact of his memoir on family relations.

“Of course, some members of my family will never forgive me for writing a book, of course they will never forgive me for lots of things,” he said.

Last week, the Duke of Sussex expressed his desire for reconciliation with the Royal Family following his legal defeat over security arrangements in the UK.
