Leonard Banning (born 1910, date of death unknown) was a British broadcaster of Nazi propaganda during World War II.
When his pre-war membership of the BUF became known to them, however, he was not interned but was allowed to live openly and without civil restrictions in Berlin on condition that he worked as a radio broadcaster for the Germans.
In early 1940 Banning began work for the "New British Broadcasting Service" unit of the Reichs-Rundfunk-Gesellschaft, German State Radio.
The effect on Banning was profound and, by the end of his time with the NBBS, he was "disillusioned, in fear of his life, half mad and wasted away".
[4] Banning returned to Britain by air after the war and was arrested at Croydon Airport on 3 November 1945 and then charged at the Old Bailey with broadcasting enemy propaganda.
