Over the following months, the FR was effectively marginalized: in March 1937, Tătărescu banned the FR's black insignia and uniforms, alongside those of other paramilitary movements (including the Guard and the PNC)."En Rumanía ya no se pueden usar más que camisas grises", in Acción, Issue 580/1937, p. 2; Clark, pp. 184–185 Early 1937 saw rumors of a tentative co-operation between Vaida and the PNȚ, which was still chaired by Mihalache. According to various outlets, Vaida had ordered his propagandists to only focus criticism on Maniu, while Tilea mediated between the two parties. The parties clashed again in February, during the international incident sparked by the Moța–Marin funeral. This event, celebrating Guardist participation in the Spanish Civil War, was attended by Axis diplomats, causing an uproar among mainstream politicians. Speaking for the FR, Ioanițescu criticized foreign meddling in Romanian affairs, but also alleged that the PNȚ had desecrated a "heroic sacrifice" by raising a political issue."Participarea unor diplomați streini la funeraliile legionarilor-eroi. Punctul de vedere al Frontului Românesc", in Gazeta Transilvaniei, Issue 15/1937, p. 1
