The 1975 county and municipality election was met with a sharp decrease in voters, with the party earning a disappointing voter turnout of 5.5% in the municipal election and 5.7% in the county election. In an opinion poll done before election day in 1975, it was estimated that half of the voters who voted for the Socialist Electoral League would not vote for the party again. The decrease in voters was due to the Labour Party's election surge during the 1973 parliamentary election. The party further decreased in popular support by the 1979 local election, earning 4.1% in the municipal and 4.4% in the county respectively.
