In 1989 the PSP initiated talks with the PPR and the PSP. Their initiative was supported by an open letter from members of trade unions, environmental movements and the arts which called for one progressive formation to the left of the PvdA. After long negotiations, which were pressured by the fall of the second Lubbers cabinet and the subsequent earlier elections, the party entered in the 1989 general election as part of GreenLeft. They were joined by the Evangelical People's Party (EVP). Ria Beckers was top candidate and she became chair of the GreenLeft parliamentary party. In 1991 the PPR dissolved itself into GreenLeft when GreenLeft became a formal political party. In the same year, GreenLeft's only MEP, former PPR-chair, Verbeek announced that he would not give up his seat in the European Parliament, to allow a former member of the PSP to enter the European Parliament. He would continue as an independent and would be top candidate for The Greens in the 1994 European election, without success.
