A year after Germany allowed the reprinting of Adolf Hitler's hate-filled autobiography Mein Kampf it remains a bestseller.

It has sold 85,000 copies and is now in its sixth print run at a time of rising xenophobia and mistrust of refugees in the country. Now a version in English is being considered for the UK and American markets.

'The number of sales has overwhelmed us,' said Andreas Wirsching, director of the Institute of Contemporary History which won the right from the state of Bavaria - holder of the copyright - to republish it.

A new version of Hitler's book Mein Kampf, pictured, has sold more than 85,000 copies

The book has been published with notes explaining Hitler's paranoid racism

The copyright was held for 70 years by the Bavarian state who blocked all attempts to reprint the hate-filled book which sold more than 12.4 million copies to people during the Nazi era

Mein Kampf - My Struggle - is a turgid, rambling book filled with loathing of Jews and Slavs who Hitler hated from his earliest days as a down-and-out in Vienna.

When he came to power it was nigh-on compulsory for every household in the Third Reich to possess at least one copy. Royalties from it made Hitler rich and it outsold the Bible.

When Nazism imploded in 1945 all Hitler's possessions - including the copyright to the book - passed into the possession of the Bavarian state, the place where his party was founded.

Authorities beat off numerous attempts to publish it down the years, afraid it would become a touchstone of faith for neo-Nazis. But when its 70-year copyright expired the state agreed to an annotated versuion being printed by the history institute.

The new version has copious notes explaining Hitler's paranoid racism to deter readers from ever believing his twisted gospel.

In April last year it became number one and it remains in the bestseller listings. Jewish groups opposed its republication.

But Wirshing insists: 'It turned out that the fear the publication would promote Hitler's ideology or even make it socially acceptable and give neo-Nazis a new propaganda platform was totally unfounded.

'To the contrary, the debate about Hitler's worldview and his approach to propaganda offered a chance to look at the causes and consequences of totalitarian ideologies, at a time in which authoritarian political views and right-wing slogans are gaining ground.'

Wirsching said many who bought the new version turned out to be readers interested in politics and history, not 'old reactionaries or right-wing radicals'.

Recently the project even won the 'Society needs Science' award with a €50,000 prize for how it 'reveals Hitler's false statements and distortions, corrects factual errors and explains the contemporary context.'

But his body is not the only one publishing it. With the copyright brake off, it is also being printed by a right-wing publisher in Leipzig called Der Schelm with no textual notes which urges readers to 'have the courage to come to your own understanding'.

Partly autobiographical, 'Mein Kampf' outlines Hitler's ideology that formed the basis for Nazism. He wrote it in 1924 while he was imprisoned in Bavaria for treason after his failed Beer Hall Putsch.

The book set out two ideas that he put into practice as Germany's leader going into World War II: annexing neighbouring countries to gain 'Lebensraum', or 'living space', for Germans, and his hatred of Jews, which led to the Holocaust.
