There was no single voting system for all member states but each of them adopted its own method, established by national law.

The United Kingdom used a one-round (first-past-the-post) 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.

However, the European Democrats had a massive loss of 32 of the 66 seats, knocking them from third to sixth largest party.

The liberals, who had already risen one place with the byelections in Spain and Portugal earlier, gained an extra seat, holding their new-found third place with both the Rainbow and Communist groups splitting post-election.
