Presidential elections were held in Portugal on 13 January 1991. The re-election of the hugely popular Mário Soares was never in doubt, specially after the then-ruling PSD, led by Prime Minister Aníbal Cavaco Silva announced its support. Therefore, the election held on 13 January 1991 was a landslide, and no second round was needed. As the election of a left-wing candidate was assured, other left-wing parties, the Portuguese Communist Party and the People's Democratic Union, presented their own candidates. The communists presented Carlos Carvalhas, who had been Assistant General Secretary of the Party a year before (Álvaro Cunhal was the secretary-general). Carvalhas would later be elected secretary-general, in 1992. On the right, as the Social Democratic Party supported Soares, the Democratic and Social Centre presented the only right-wing candidate, Basílio Horta. Mário Soares achieved the majority of the votes in every district of the country, and 295 of the then 305 municipalities. His score was the biggest ever in a presidential election in Portugal.

Electoral system

Any Portuguese citizen over 35 years old has the opportunity to run for president. In order to do so it is necessary to gather between 7,500 and 15,000 signatures and submit them to the Portuguese Constitutional Court. According to the Portuguese Constitution, to be elected, a candidate needs a majority of votes. If no candidate gets this majority there will take place a second round between the two most voted candidates.
