Following his release in 1944, Moran set up his own organisation in Derby, the Order of the Sons of Saint George, which represented itself as a patriotic movement. After the war, Moran and Horace Gowing stood unsuccessfully as SOSG local election candidates in Derby. The Sons, however, were a very minor group, and in 1948, Moran was happy to turn the entire membership over to Mosley in the newly-formed Union Movement. Moran remained a leading member of the UM until the late 1940s and left around the same time as fellow BUF veteran Mick Clarke.
