Socialist Party of Batavia

The Socialist Party of Batavia (SPB, Dutch: Socialistische Partij van Batavia) is a left-wing, democratic socialist political party in Batavia. Its current leader is Steef Kophoff, since 2014.

The Socialist Party has been in opposition for all of its history except for two periods: 1967 to 1972 and 2007 to 2010. This is largely due to its perceived extremism and the reluctance of the more moderate parties to cooperate with it on legislative matters.
