King Charles get to tipping point over Prince Harry issue, says insider

King Charles was utterly disappointed with Prince Harry after he crossed a lines.

His Majesty was extremely upset when Harry dragged down Queen Camilla in his memoir ‘Spare.’

“It was the last straw. Harry was well aware how Camilla would be a red line for his father and he crossed with flagrant disregard anyway," a source told the Express. "The King felt without a doubt it crossed a line - it was the ultimate act of disrespect."

In his memoir, Harry wrote: "I had complex feelings about gaining a step parent who, I believed, had recently sacrificed me on her personal PR altar," he wrote. "In a funny way I even wanted Camilla to be happy. Maybe she'd be less dangerous if she was happy?"

Meanwhile, Camilla’s friend, Lady Lansdowne, told The Sunday Times: "Of course it bothers her, of course it hurts. But she doesn't let it get to her. Her philosophy is always, 'Don't make a thing of it and it will settle down - least said, soonest mended.'
