* These parties received a 2nd (surplus) seat
This list shows all occasions since 1937 when a party received a score of 1-2 times the quota. Since 1937 it is necessary for a party to receive as many votes as the quota to win their first seat. In the period 1918-1933 a number of votes might have resulted in a (surplus) seat.
Remarkable is that in 9 out of 26 occasions it involves the Christian-conservative GPV. Before winning their first seat in 1963, the party had taken part in 1952, 1956 and 1959. In all three occasions, they scored very close to the (later) quota of 0,667% (in 1952 & 1956, a quota of 1 % was used). Only in the 1971 and 1972 elections, the GPV won more than 2 times the quota, the highest score was 2,66 times the quota in 1972. GPV voters were usually members of the Reformed (Liberated) Church, a 1944 splitoff of the Reformed Church, making it a small but stable party. Its vote (and seat) gains in the 1970s and 1990s might be explained by the respect their sole MPs earned for their work in Parliament as men of principle, making them acceptable for voters outside their Church (and even for non-Christian voters).
Only four single seat parties never received more than 1 seat, RKPN, U55+, CP and EVP. All four parties have only been represented in parliament for 1 period.
