A biography of Hitler that was commissioned by Josef Stalin and discovered by German historian Matthias Uhl last year is to be published. Stalin commissioned the book to understand the psychology of Hitler.

The book is based on the two year interrogation of Hitler's butler Heinz Linge and SS adjutant Otto Guensche. Both had worked for Hitler for ten years and both were captured in Hitler's bunker by Russian troops during the fall of Berlin.

The book is to be published in Germany in March and in the UK in November. The publisher claims the book contains astonishing detail and insight concerning Hitler.
