In April 1958, Tyndall and Bean founded their own extreme-right group, the National Labour Party (NLP). The group was based at Thornton Heath, Croydon and attracted its early membership from former LEL members living in south and east London. According to the historian Richard Thurlow, the NLP promoted an "English" variant of Nazism, and was more pronounced in its "explicit racism" than the LEL had been, focusing less on bemoaning the decline of the British Empire and more on criticising the arrival of non-white immigrants from former British colonies.
