Rather, 43 Group sought to prevent the Union Movement mobilising and gathering support, remembering that the Nazi party had gained prominence in a similar fashion as the Brownshirts on the streets of post-World War I Germany. The 43 Group was voluntarily disbanded on 4 June 1950, as its members considered that the immediate threat had passed. Mosley's Union Movement remained active throughout the 1950s, but it was not until 1962, when the unrelated 62 Group was formed in the 43 Group's image, that British fascists again encountered any significant privately organised street-level resistance. The overall effect of 43 Group is unclear. Morris Beckman argued that it was crucial in stopping a resurgence of fascism in post-war Britain. In 2004, the group was the subject of BBC Radio 4 programme "A Rage in Dalston", part of The Archive Hour series, presented by Alan Dein. September 2015, it was announced that BBC2 and NBC were co-developing a 6-part drama series alongside surviving members of The 43 Group and produced by The Tenafly Film Company and Tiger Aspect Drama.
