The National Solidarity Party (Portuguese: Partido da Solidariedade Nacional, PSN) was a political party in Portugal.
The party was established in 1990 and sought to represent the interests of pensioners.[1] In the 1991 parliamentary elections it received 1.68% of the vote and won a seat in the Assembly of the Republic,[2] taken by its president, Manuel Sérgio. However, its vote share was reduced to just 0.21% in the 1995 elections, resulting in the party losing its seat.[2]
The 1999 elections saw the party's vote share remain at 0.21%. After failing to regain parliamentary representation, it did not contest any further elections,[2] and was declared defunct in 2006.[1]
The party also contested the elections for the European Parliament in 1994 and 1999, winning no seats in both cases.
