Prince William was 'resentful' of Prince Harry's North Pole visit

Prince William was upset Prince Harry went to the North Pole alone.

Writing in his memoir 'Spare', Harry notes how he had an argument with William over taking up Africa as his project.

He mentions: "Over several more heated discussions, it emerged that Willy, when I’d gone to the North Pole, had sadly been resentful. He’d felt slighted that he hadn’t been the one invited."

Harry added: "At the same time he also said that he’d stepped aside, gallantly, that he’d permitted me to go, indeed that he’d permitted all my work with wounded soldiers. I let you have veterans, why can’t you let me have African elephants and rhinos?"

Prince Harry's memoir 'Spare' is now out in stores.
