The 1989 European Parliament election, was the third European election to be held in the United Kingdom. It was held on 15 June. The electoral system was First-past-the-post voting in England, Scotland and Wales and Single transferable vote in Northern Ireland. The turnout was again the lowest in Europe.
This election saw the best performance ever by the Green Party (UK) (formerly the Ecology Party), collecting over 2 million votes and 15% of the vote share. It had only received 70,853 as the Ecology Party in the previous election. However, because of the first past the post system, the Green Party did not gain a single MEP, while the Scottish National Party received 1 seat with only 3% of the vote share. The Green Party's vote total of 2,299,287 remains its best performance in a national election, as does its percentage result of 14.5%.
The election also saw Labour overtake the Conservatives for the first time in any election since October 1974 and the first time ever in a European election, winning 13 more seats.
Two by-elections to the British Parliament also took place on the same day in the Vauxhall and Glasgow Central constituencies - Labour held both seats.
Total votes cast: 15,361,267
Total votes cast – 534,811.
