In June 1980, Tyndall founded the New National Front (NNF). The NNF claimed that a third of the NF's membership defected to join them. Tyndall stated that "I have one wish in this operation and one wish alone, to cleanse the National Front of the foul stench of perversion which has politically crippled it". As his choice of party name suggested, he remained hopeful that his breakaway group could eventually be re-merged back into the NF. There developed a great rivalry between the two groups, and as the NF's new leadership moved it away from the Tyndallite approach, Tyndall realised that he may never have the opportunity to regain his position within it.
