Chirac made his first run for president against Giscard d'Estaing in the 1981 election, thus splitting the centre-right vote. He was eliminated in the first round with 18% of the vote. He reluctantly supported Giscard in the second round. He refused to give instructions to the RPR voters but said that he supported the incumbent president "in a private capacity", which was interpreted as almost "de facto" support of the Socialist Party's (PS) candidate, François Mitterrand, who was elected by a broad majority.
