Outcome With a record high turnout of 79.97%, the Spanish political landscape underwent an electoral earthquake. The ruling
Union of the Democratic Centre (UCD) was devastated; it lost 157 seats and fell to 11, a 93.5% loss from 1979. In terms of votes, it went from 6.3 million down to 1.4 million, a loss of 4.9 million votes or 77.8% of its 1979 vote, and plunged to 6.8% of the share to the 34.8% it had won in 1979—a loss of 80.5% of its share. Of its 11 seats, 5 were obtained in
Galicia, 3 in
Castile and León, 2 in the
Canary Islands and only 1 in
Madrid, winning no seats in all other regions. Incumbent Prime Minister
Leopoldo Calvo-Sotelo, who stood in second place in the Madrid list, lost his seat—the only time in recent Spanish history that a sitting prime minister seeking re-election as MP was unseated. It was the worst defeat, both in absolute terms and in terms of percentage of seats lost, for a ruling party at the national level in Spain, and one of the worst defeats ever suffered by a governing party in any country at the time, rivaling only with the collapse of
Christian Democracy at the
1994 Italian election or the
Progressive Conservatives' downfall at the
1993 Canadian election. The
Spanish Socialist Workers' Party (PSOE) swept the popular vote in nearly all regions of the country—only AP and
PNV wins in Galicia and the
Basque Country denied them a clean sweep of the entire national territory. They won a majority of seats in every region but Galicia,
La Rioja and the
Balearic Islands, and obtained an astounding 60% in Spain's most populous region,
Andalusia—a feat never to happen again. In
Catalonia it obtained a 23-point lead over the second most-voted party, a result that would only be surpassed by the PSOE's own result in the
2008 election. Andalusia and Catalonia would become from that point onwards as the main strongholds of PSOE support, which was to remain the dominant political force in both regions in each general election until
2011. Overall, the PSOE won 202 seats—its best historical performance and the best performance of any party in a Spanish general election. This gave them an overwhelming majority in the Congress, nearly doubling the seat-count of its immediate competitor. The PSOE was also the only party to win seats in every district, the first of only three times since the
Spanish transition to democracy that this has happened—the other two being PP results in the 2000 and 2011 elections. The
People's Alliance–People's Democratic Party (AP–PDP) coalition had a major breakthrough, gaining a substantial portion of UCD previous support, displacing it as the main party to the right-of-centre in Spain and becoming the country's main
opposition party. Despite only topping the polls in Galicia, its results elsewhere where still considered impressive for a party that, in the 1979 election, had only obtained 6% of the vote and 9 seats. It obtained 107 seats—despite opinion polls predicting that it would be well-below the 100-seat mark—and climbed up to 5.5 million votes. It did not win any seats, however, in the districts of
Ceuta and
Melilla, which essentially worked under a
FPTP system. The AP-UCD-PDP coalition in the Basque Country won 2 seats, 1 each for
Álava and
Biscay, being left out from
Gipuzkoa. It would also be the only one of three times that AP and its successor, the PP, would win a seat in the district of
Girona. The
Communist Party of Spain (PCE) suffered from PSOE's growth, falling from 23 seats to 4—a loss of 82.6%—and losing 1.1 million votes to 850,000 —a loss of 60%. Furthermore, it fell to 4.02% of the share, from 10.8% in 1979. As a result of not reaching the required 5% threshold and 5 seats to obtain a parliamentary group in Congress of its own, the PCE was forced into the Mixed Group, with the fear of becoming an extraparliamentary party at the next election remaining for the entire legislature. On the other hand, nationalist parties such as PNV and
CiU benefitted from the UCD's collapse and enlarged their political representation. CiU gained 4 seats for a total of 12, placing among the top two in Catalonia, a first in a general election since 1977.
Government formation Congress Speaker Gregorio Peces-Barba (
PSOE), in an uncommon gesture, did not cast a ballot and maintained strict neutrality, as his party's lopsized majority all but guaranteed González's election. The 202-strong PSOE absolute majority would come to be known as the "roller" (
rodillo in
Spanish), in reference to the party's overwhelming parliamentary power. Any bill submitted by González' government was assured to be approved by Congress, with the parliamentary process of law-making and approval turning into a mere formality. ==Legacy==
