William and Kate make first outing since 'Spare' release

STORY: In his book "Spare", Harry divulges that he had begged his father not to marry his second wife Camilla, now the queen consort. The book also delivered numerous other revelations, including that elder brother and heir to the throne William had knocked him over during a heated argument.

Harry also used promotional interviews to double down on his claims that some royals, including Camilla and William, and their aides had leaked damaging stories to tabloid papers about him or his American wife Meghan in order to protect themselves or enhance their reputations.

A smiling and happy-looking William and Kate, who he also criticizes in his book were visiting a hospital in northern England. They too made no public reference to the saga.

So far, neither Buckingham Palace nor aides for any of the royals have commented on Harry's disclosures.
