Lady Victoria Hervey, who dated Prince Andrew in 1999, believes Prince Harry's "self-sabotaging his relationship with his brother" will lead to his exile from the royal family.
Talking to The Mirror on Monday, the socialite said, “It’s becoming a bit of a blood sport. Harry is getting himself closer and closer to being exiled. I think he’s only one or two steps away from that happening.”
"He's pushing the boundary as much as he can so that happens and he can wallow in Victimhood," she continued.
Lady Victoria, 46, then compared Harry's connection with his older brother, Prince William, to that of Cain and Abel, Adam and Eve's first two sons, in Genesis.
Cain murders his sibling in the account because God was jealous of Abel's offering over his own.
“I think Prince Harry is self-sabotaging his relationship with his brother so much that it has now become Cain and Abel,” she noted.
Harry, 38, and William, 40, have transitioned from being a unified front to a notoriously contentious relationship.
The Duke of Sussex claimed in his recently released explosive memoir, "Spare," that he and William got into a squabble over Meghan Markle that allegedly turned physical.
According to Harry, the two yelled at each other until William pushed him to the floor, forcing him to land on a dog bowl and injure his back.
He also accused his brother of neglecting him while they were both students at Eton, of ignoring him during his time in the military, and of being jealous that he had invented the Invictus Games.
He also accused the Prince and Princess of Wales of being unwelcoming to Markle, even urging him to dress up as a Nazi at an infamous fancy dress party.
It was discovered last week that King Charles had asked his son and daughter-in-law to leave their UK home, Frogmore Cottage, the day after "Spare" was released.
Meanwhile, the Duke and Duchess of Sussex revealed that they have been invited to Charles' upcoming coronation but have not stated whether or not they will attend.
