William and Kate ‘howled with laughter’ at Harry’s infamous Nazi costume

William and Kate ‘howled with laughter’ at Prince Harry’s infamous Nazi costume, according to claims leaked from the Duke of Sussex’s soon to be published book.

Harry writes that he phoned the couple to ask them whether he should chose a pilot’s uniform or a Nazi one ahead of a party in early 2005 and that William and Kate suggested the latter, both howling with laughter when he went home and tried it on for them.

Harry, then 20, sparked outrage and was widely condemned when a photograph of him in the uniform complete with swastika ended up on the front page of a newspaper. He said in his Netflix documentary: “It was probably one of the biggest mistakes of my life.”

So far, Kensington Palace and Buckingham Palace have declined to comment on the excerpts from Harry’s book which emerged just days before the explosive tell-all autobiography ‘Spare’ is due to be published.

The Duke of Sussex has also claimed he was physically attacked by his brother the Prince of Wales and knocked to the floor during a furious confrontation over the Duchess of Sussex.

The newspaper said it was able to obtain a copy of Spare despite the tight pre-launch security.
