Britain's leading bookseller has apologized for a festive promotion trumpeting Adolf Hitler's "Mein Kampf" as the ideal Christmas gift.

The Nazi leader's autobiography was on prominent display at a branch of Waterstone's in Huddersfield, northern England, complete with a seasonal sticker hailing it "the perfect present."

An accompanying message delivered a glowing recommendation from a staff member, describing the infamous anti-Semitic manifesto as "an essential read for anyone."

The book was also spotted on display at shops in several major cities including Manchester and Liverpool, according to The Jewish Chronicle.

It quoted one customer, Jonathan Levine, 44, as saying, "I would be most obliged if Waterstone's would explain what lies behind the apparent zeal on their part to promote this disgusting work."

Hitler wrote "Mein Kampf" -- My Struggle -- after he was jailed for the failed Beer Hall Putsch of 1923.

The 700-page tract, which laid bare the despot's venomous hatred of Jews and warped racial agenda, achieved a circulation of around 12 million copies by 1945.

Waterstone's responded to The Chronicle's story by issuing an apology and insisting staff would be reminded of the "sensitivities" surrounding the sale of "Mein Kampf."

"We do not believe we actively promote this book; our customers are capable of forming their own opinions on whether to purchase it or not," said a spokesperson for Waterstone's, which operates around 300 stores across the UK.

"However, you do raise a couple of instances where we have obviously got things wrong. The book should not be stocked in any politics section, and our Huddersfield branch should not have used inappropriate seasonal stickers on the book."
