The Icelandic parliamentary election of 1987

In the election to the Althingi on 25 April 1987, the established party system in Iceland received its greatest blow so far. The four main parties between them managed only three-quarters of the valid votes, the Independence Party and the People's Alliance, both suffered their worst defeats ever. The new parties had a field day, as the Citizens' Party—the first major splinter group from the large Independence Party since its foundation—and the Women's Alliance received over 10 per cent of the votes each. Thus, the signs of crisis in the established party system—increasingly visible since around 1970—indicate an uncertain future for the four-party format in Icelandic politics.
