Social Democratic Party (Guinea-Bissau)

The party was established in 1995 by Joaquim Baldé. In the 1999–2000 general elections Bald was nominated as the party's presidential candidate, but finished eighth with 2.3% of the vote. In the parliamentary elections, the party won three seats in the National People's Assembly.^[1]

Prior to the 2004 parliamentary elections the party joined the Electoral Union alliance, which won two seats. It did not contest the 2005 presidential elections, but supported runner-up Malam Bacai Sanhá.^[1] In 2007 António Samba Baldé became party leader, and in the parliamentary elections the following year, the party failed to win a seat.^[1]

The PSD did not nominate a candidate for the 2009 or 2012 presidential elections. In the 2014 general elections it did not put forward a candidate for president, but ran in the parliamentary elections, receiving just 0.4% of the vote and failing to win a seat.

The alliance contested the 2023 legislative election as part of a PAIGC-led coalition, the Inclusive Alliance Platform – Terra Ranka, that won 54 out of the 102 available seats.^[2]
