In 1948, party member Johann de Miranda [nl], on behalf of the PSV, went to the First Round Table Conference in the Netherlands, where he pleaded for universal suffrage for men and women.
At the 1973 elections, the PSV belonged to the coalition National Party Combination (NPK), led by Henck Arron, who obtained 22 of the 39 seats.
In 1977, the NPK once again won 22 of the 39 seats in a slightly changed composition, with another two PSV ministers in the cabinet.
As a result of the military coup in 1980 led by sergeant Dési Bouterse, this government came to an end prematurely.
After the restoration of democracy, the PSV no longer played a major role in Surinamese politics.
