Along with the rest of the BNP, Fountaine became a founder member of the
National Front (NF), although problems developed from the outset owing to his fractious relationship with
A. K. Chesterton. Nonetheless, he was the party's first parliamentary election candidate in
Acton in a
by-election in 1968, where he gained 1400 votes (over 5% of the total) and came fourth. Alarmed by the
protests of 1968, Fountaine believed that revolution was sure to follow in continental Europe and, fearing similar protests in the UK, told NF members to report to the police in order to offer their services in the event of revolution or civil war. Despite this, Tyndall subsequently courted the support of Fountaine following the election of
John Kingsley Read, who had emerged ahead of Painter as populist leader, as NF Chairman. Fountaine agreed to work with Tyndall, and at the 1975 conference proposed one of Tyndall's favoured ideas, changing leadership elections from the existing system of National Directorate members only to a party-wide vote, a motion that was narrowly defeated. In November 1975, Tyndall was expelled from the party while Fountaine and
Martin Webster were suspended for their part in recent machinations, although all three were reinstated by court order the following month. Kingsley Read and his supporters broke away to form the
National Party soon afterwards. Fountaine returned to public notice under Tyndall and was adopted as the party's candidate for the
1976 Coventry North West by-election. His campaign secured only 3% of the vote in a city where the local branch had been divided by the National Party split, although Fountaine did at least beat Kingsley Read. Fountaine's alliance with Tyndall did not last, however, and he became openly critical of what he saw as the
neo-Nazism of Tyndall and Webster, as well as their attempts to recruit elements he saw as undesirable, such as
racist skinheads and
football hooligans. As a result, by 1978 Fountaine had become a focus for dissident activity within the NF. In the 1979 election, Fountaine stood as National Front candidate in the Norwich South constituency, polling 264 votes (0.7%). ==Later years==
