The 1989 European Parliament election was a held on June Wednesday 15 to Sunday 18 across the 12 European Union member state in June 1989. It was the third European Parliament election but the first time that Spain and Portugal voted at the same time as the other members they joined in 1986. Overall turnout dropped to 59%.
These were the first elections Portugal and Spain took part in with the other states. Spain was allocated 60 seats and Portugal was allocated 24; the number of seats for the other states remained the same, raising the total number of seats from 434 to 518.
The Socialists held their third consecutive victory, rising to 180 seats (166 pre-election), with the People's Party managing to win only 8 extra seats. 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.
