A royal author has claimed that Prince Harry’s friends thought he was “nuts” after he brought Meghan Markle to a weekend gathering during the early days of their romance.

Eager to introduce Meghan to his longtime circle, Harry invited her to a shooting weekend at Sandringham, a tradition within the royal family that he and Prince William had grown up with. According to Tom Bower’s book, Revenge: Meghan, Harry and the War Between the Windsors, what followed was a tense three days that Harry hadn’t anticipated.

Bower wrote: “Harry was looking forward to endless banter, jokes – and a lot of drinking. He had not anticipated Meghan’s reaction.” He claims the duchess didn’t appreciate his friends’ politically incorrect humor at dinner and made her feelings clear.

“Without hesitation, Meghan challenged every guest whose conversation contravened her values. According to Harry’s friends, again and again she reprimanded them about the slightest inappropriate nuance. Nobody was exempt, Harry’s world would not be her world.”

The author added that Harry’s friends questioned her “wokery” and felt she dampened the atmosphere. “She lacked any sense of humour,” Bower wrote. After the weekend, group chats among Harry’s friends reportedly buzzed with remarks such as: “‘OMG what about HER?’; ‘Harry must be f*****g nuts’; and ‘She’s a total nightmare.’”
