1984 European Parliament election
The 1984 European Parliament election was the first since the inaugural election of 1979 and the 1981 enlargement of the European Community to include Greece. It was also the last before the accession of Spain and Portugal in 1986.
Results showed centre-left and right-wing MEPs profiting at the expense of the far-left and centre-right. The Socialists consolidated their position as the biggest group in the Parliament, and there were notable changes for the smaller groups, with far-right MEPs forming a group and the coalescence of the Green and Regionalist group known as "Rainbow". Overall turnout dropped to 61%. No majority was achieved.
Electoral system
There was no single voting system for all member states; each of them adopted its own method, established by national law.The United Kingdom used a one-round system of 78 constituencies in England, Wales and Scotland, while in Northern Ireland 3 proportional seats were allocated. Belgium, Ireland and Italy used a proportional system with subdivision of the territory into constituencies. Denmark, France, West Germany, Greece, Luxembourg and the Netherlands used a single national proportional system, although in the case of Denmark Greenland had its own constituency with the allocation of one seat and in the case of West Germany the three seats for the West Berlin area were not directly elected but were chosen by the Berlin House of Representatives, given the particular status of the city.

Seat changes
The number of seats was the same as before for each member state that took part in the 1979 election. Greece, which had joined in 1981, was allocated 24 new seats. This raised the number of seats to 434 from 410.Election and regrouping
