Adolf Hitler may have been gay, according to a new book.

The publication, Adolf Hitler: The Final Analysis, by physician, Andrew Norman, studies how the leader of Nazi Germany’s mental and physical state affected his judgement and conduct as he led the country into Word War Two.

The book suggests the leader had a homosexual past which left him open to blackmail.

Mr Norman discovers that Hitler may have suffered from a variety of conditions which led to his fanaticism including schizophrenia, paranoia and anti-social personality disorders.

He also claims many of the warmonger’s colleagues were gay, such as Ernst Rohm, the head of the Nazi storm troopers, known as the Brownshirts.

Gay people were a target as well as Jews, gypsies and any non-Aryan, for Nazi concentration camps between 1938 and 1945.
