In 1986, the surprising rise of Mário Soares, who reached the second round in the presidential election, defeating the party's candidate, Salgado Zenha, made the party call an extra congress. The eleventh congress was called with only two weeks' notice, in order to decide whether or not to support Soares against Freitas do Amaral. Soares was supported, and he won by a slight margin. Had he not been supported by the PCP, he would have probably lost. In 1987, after the resignation of the government, another election took place. The PCP, now in the Unitary Democratic Coalition (Portuguese: "Coligação Democrática Unitária" or CDU) with the Ecologist Party "The Greens" (Portuguese: "Partido Ecologista "Os Verdes"" or PEV) and the Democratic Intervention (Portuguese: "Intervenção Democrática" or ID), saw an electoral decline to 12.18% and 31 seats.
