{{See also|CU–SGP}}
Until 1963, the SGP was relatively isolated in parliament. The strongly antipapal SGP refused to cooperate with either the [[Catholic People's Party]] or the secular [[People's Party for Freedom and Democracy]] (VVD) and [[Labour Party (Netherlands)|Labour Party]] (PvdA). The also Protestant, larger [[Anti-Revolutionary Party]] (ARP) had some sympathy for the SGP, but cooperated more tightly with the KVP and the other Protestant party, the [[Christian Historical Union]] (CHU). In 1963 another orthodox Protestant party, the [[Reformed Political League]] (GPV) entered parliament, in 1981 they were joined by the [[Reformatory Political Federation]] (RPF). Together these three parties formed the "Small Christian parties". They shared the same orthodox Protestant political ideals and had the same political strategy, as [[testimonial party|testimonial parties]]. They cooperated in municipalities, both in [[municipal executive]]s, where the parties were strong, as well as in common municipal parties, where the parties were weak. In the [[1984 European Parliament election in the Netherlands|1984 European Parliamentary election]] the parties presented a common list and they won one seat in parliament. After 1993 the cooperation between the GPV and the RPF intensified, but the SGP's position at the time on [[female suffrage]] prevented the SGP joining this closer cooperation. However, in 2000 the GPV and RPF merged to form the [[Christian Union (Netherlands)|ChristianUnion]] (CU). Traditionally the SGP and the CU worked together closely as they were both based on Protestant Christian [[Christianity and politics|politics]]. Recently however, as the CU has moved more towards the centre-left,{{citation needed|date=August 2012}} discernible differences of philosophy between the SGP and CU have caused the parties to not join in elections. The most notable example was the 2011 Senate election where the SGP and CU did not combine their votes.<ref>{{cite episode |title=ChristenUnie en SGP lastig door één deur |url=http://archief.wereldomroep.nl/nederlands/radioshow/christenunie-en-sgp-lastig-door-%C3%A9%C3%A9n-deur |archive-url=https://web.archive.org/web/20151208233452/http://archief.wereldomroep.nl/nederlands/radioshow/christenunie-en-sgp-lastig-door-%C3%A9%C3%A9n-deur |archive-date=8 December 2015 |series=Nieuwslijn Magazine |network=Radio Netherlands Worldwide |date=26 May 2011 |access-date=8 December 2015 }}</ref>
