Dissatisfied members of the Roman Catholic Katholieke Volkspartij (KVP) and the Protestant Antirevolution aire Partij (ARP) founded this political party in 1968, which nev ertheless did not become a Christian party. The party’s main issues were the environment, disarmament, and foreign aid. The PPR joined the Joop den Uyl cabinet between 1973 and 1977. Its best known leaders were Dr. Bastiaan (“Bas”) de Gaay Fortman (1937– ) and Brigitta Catherina (“Ria”) Beckers-de Bruijn (1938–2006). In 1989, the PPR merged into GroenLinks (GL, Green Left).
