He also stood as a candidate for the National Front (FN) at a time when the party sought out alliances with more radical groups due to the impact on their support that the Parti des forces nouvelles (PFN) was having.[1] Fredriksen was a strong critic of the PFN, arguing that they were just a more militant version of mainstream Gaullism.[2] As such Fredriksen was the FN candidate in Seine-Saint-Denis in the 1978 election where his 1.4% vote share was actually one of the higher results for the far right in an election in which they failed to prosper.[3] Fredriksen left the FN after the murder of François Duprat, feeling that Jean-Marie Le Pen was too 'soft' for his liking.[4]
Fredriksen's controversial opinions made him a target for direct attacks more than once. On 19 September 1980 Fredriksen and a group of his supporters were attacked at the Paris palace of justice by a group of people claiming to represent the Jewish Defense Organization. Fredriksen suffered a further attack on 12 October that year and had to be treated in hospital.[5] In 1981, Frederiksen was sentenced to 18 months in prison, with 12 months suspended, plus 33,000 Francs in fines, for racist remarks and pro-Nazi sentiments in Notre Europe.[6]
