A rare anti-Nazi leaflet dropped over Germany by the RAF during the Second World War will be presented to the UK Holocaust Centre this week.The document is one of the few surviving White Rose leaflets produced by brave students at Munich University.The White Rose resistance movement was behind thousands of copies of the leaflets, which gave details of the Holocaust and supported the ideals of democracy, freedom and religious tolerance. The six core members of the group, including Sophie and Hans Scholl, were executed in 1943. They are now regarded as heroes for their courageous opposition to the Third Reich.The text of their sixth leaflet was smuggled out of Germany to Britain. In July 1943, copies were dropped over Germany by Allied aircraft.Collector William Kaczynski is now donating one of the leaflets to the Holocaust Centre, a memorial and education museum in Newark, Nottinghamshire.
