The NF's first year was marked by a power struggle between the ex-LEL and ex-BNP factions. The ex-LEL faction were unhappy with the behaviour of ex-BNP members, such as their propensity for political chanting, while the ex-BNP faction criticised Chesterton's elitist pretensions by calling him "the Schoolmaster". At the invitation of the ex-BNP faction, in June 1967, Tyndall discontinued the GBM and called on its members to join the NF. Contravening his earlier commitment to keep him out, Chesterton welcomed Tyndall into the party. Tyndall had written a book titled "Six Principles of British Nationalism" in which he moved away from explicit neo-Nazism in favour of a more moderate approach; he thought this the most important factor in changing Chesterton's mind on allowing GBM members to join the NF. Tyndall's magazine, "Spearhead"—which was originally sold as "an organ of National Socialist Nazi opinion in Britain"—dropped its open commitment to neo-Nazism and backed the NF, eventually becoming the party's "de facto" monthly magazine. The party held its first annual conference in October 1967, which was picketed by anti-fascist demonstrators.
