FED-UP WILLIAM TWISTS KNIFE IN KING'S BACK!

Fights back after mean stepmom Camilla insults Kate

- 

IVID Prince William has severed ties with his father, King Charles, in a secret war triggered by Queen Camilla’s cruel treatment of her royal rival Princess Kate.

And the future monarch — now the Prince of Wales — flexed his muscle by evicting his father and stepmother from one of their most cherished properties, which he inherited along with his new title.

Even though the 74-year-old king and his fuming heir, 41, strive to keep up cordial appearances in public, their furious feud threatens to rip the monarchy apart, charge palace sources.

“William has hidden his pent-up feelings about his evil stepmother for decades, but they exploded in a torrent of retaliation when he learned she was badmouthing his wife and family,” reveals a high-level royal courtier. “He’ll never forgive her. And he’s hell-bent on stopping her!” 

Meanwhile, Charles is said to be too weak-willed to rein in his domineering queen.
