Brons began his political career in 1964 when, aged seventeen, he joined the National Socialist Movement (NSM), a Neo-Nazi organisation founded on Adolf Hitler's birthday by Colin Jordan. In 1980, Searchlight published two letters Brons had written in 1965 to Françoise Dior, Jordan's wife, in which he mentioned meeting an NSM member who "mentioned such activities as bombing synagogues", stating in response to this that: "On this subject I have a dual view, in that I realise that he is well intentioned, I feel that our public image may suffer considerable damage as a result of these activities. I am however open to correction on this point."Duncan Campbell (8 June 2009). "Andrew Brons: the genteel face of neo-fascism", The Guardian. London. The second letter requested materials such as a swastika, a copy of the Horst-Wessel-Lied, and posters and stickers in furtherance of Brons' goal of forming a local NSM group.
