Supported by a disparate and sometimes hostile alliance of far-rights groups, and lacking the necessary party structure, Tixier-Vignancour's failed at 5.2% of the votes in December 1965. After that, he publicly called for a vote in favor of Socialist candidate François Mitterrand in the second round. Deceived by his multiple renunciations—from the moderation of stance to his support of Mitterrand—, Le Pen decided to quit the campaign. Votes for Tixier-Vignancour were heavily concentrated in the south of France, a region which had already seen the highest levels of "no" votes in the Évian Agreements referendum and where many Pieds-noirs had settled after their recent repatriation from Algeria in 1962.
