The '''2005 Portuguese legislative election''' took place on 20 February. The election renewed all 230 members of the [[Assembly of the Republic (Portugal)|Assembly of the Republic]].

These elections were called after the decision of [[President of Portugal|President]] [[Jorge Sampaio]] on 30 November 2004 to dissolve the [[Assembly of the Republic (Portugal)|Parliament]] as an answer to the political instability caused by the government led by [[Pedro Santana Lopes]] ([[Social Democratic Party (Portugal)|PSD]]) in coalition with the [[People's Party (Portugal)|PP]]. Santana Lopes had become Prime Minister in July 2004, after [[José Manuel Durão Barroso]] left the country in order to become [[President of the European Commission]] in a decision that divided the country, because many Portuguese were expecting that the Socialist President [[Jorge Sampaio]] would dissolve the Parliament and call a legislative election. However, after five unstable months, President Sampaio decided to dissolve Parliament and call fresh elections. The Prime Minister nevertheless announced the resignation of the government on 11 December, in an action with no practical effects whatsoever.

The campaign started officially on 6 February and the major topics were the problematic state of the country's finances, [[unemployment]], [[abortion]] and even [[José Sócrates]]'s alleged homosexuality.<ref>{{cite news |last=Santos Costa |first=Filipe |date=2 February 2005 |title=Santana nega ter feito insinuações |trans-title=Santana denies having made insinuations |url=https://www.dn.pt/arquivo/2005/interior/santana-nega-ter-feito-insinuacoes-608079.html|language=pt |newspaper=Diário de Notícias |access-date=8 June 2016}}</ref><ref>{{cite news |last=Paixão |first=Paulo |date=23 September 2009 |title=Temas que marcaram a campanha das legislativas de 2005 |trans-title=Themes that marked the 2005 election campaign |url=https://expresso.sapo.pt/dossies/dossiest_actualidade/dossie_eleicoes_2009/temas-que-marcaram-a-campanha-das-legislativas-de-2005=f537185 |language=pt |newspaper=Expresso |access-date=8 June 2016 }}</ref>

Headed by Sócrates, the centre-left [[Socialist Party (Portugal)|Socialist Party]] (PS) won the election with a landslide victory, winning in 19 of the 22 electoral constituencies, including in districts such as [[District of Viseu|Viseu]] and [[District of Bragança|Bragança]] that historically voted for the right. The Socialist Party conquered its first absolute majority, receiving 45 percent of the electorate vote and 52 percent of the seats in the Parliament, making this the Socialists' largest ever victory in terms of vote percentage and seat count as of 2022. The centre-right parties, mainly the Social Democrats, were punished for their performance in government, and lost more than 11 percentage points they had garnered in the previous election. On the left, the Left Bloc achieved its best result ever and made the biggest climb, gaining 5 MPs, while the CDU (Communists and the Greens) gained 2 MPs and reversed their downward trend of the last elections.

[[Voter turnout]] was the highest since [[1995 Portuguese legislative election|1995]], as 64.3 percent of the electorate cast a ballot.

== Background ==
In the aftermath of the [[2002 Portuguese legislative election|2002 legislative election]], PSD and CDS–PP formed a coalition government, the first coalition between both parties in nearly 20 years.<ref>[https://sicnoticias.pt/arquivo/legislativas-2019/2019-10-01-2002-O-regresso-da-coligacao-de-Direita-ao-poder "2002: O regresso da coligação de Direita ao poder"], ''SIC Notícias'', 1 October 2019.

Deep disagreements and disputes within the [[Social Democratic Party (Portugal)|Social Democratic Party]] began to derail the government led by [[Pedro Santana Lopes]], the successor of Durão Barroso as prime minister.<ref>[https://observador.pt/especiais/as-trapalhadas-de-santana-em-2004-que-rio-apoiou-e-marcelo-arrasou/ "As "trapalhadas" de Santana em 2004 (que Rio apoiou e Marcelo arrasou) "], ''Observador'', 21 December 2017.

=== Electoral system ===

[[File:Eleições legislativas 2005.gif|thumb|Official logo of the election.]]
The [[Assembly of the Republic (Portugal)|Assembly of the Republic]] has 230 members elected to four-year terms. Governments do not require absolute majority support of the Assembly to hold office, as even if the number of opposers of government is larger than that of the supporters, the number of opposers still needs to be equal or greater than 116 (absolute majority) for both the Government's Programme to be rejected or for a [[motion of no confidence]] to be approved.<ref>{{cite web|url = http://www.en.parlamento.pt/Legislation/CRP/Constitution7th.pdf|title = Constitution of the Portuguese Republic|access-date = 2019-12-29|archive-url = https://web.archive.org/web/20160303222446/http://www.en.parlamento.pt/Legislation/CRP/Constitution7th.pdf|archive-date = 2016-03-03|url-status = dead}}</ref>

The number of seats assigned to each district depends on the [[district magnitude]].<ref>{{cite web|url=http://www.tcd.ie/Political_Science/staff/michael_gallagher/ElSystems/Docts/effthresh.php |title=Effective threshold in electoral systems |publisher=Trinity College, Dublin |access-date=2015-10-21}}</ref> The use of the [[d'Hondt method]] makes for a higher effective threshold than certain other allocation methods such as the [[Largest remainder method|Hare quota]] or [[Sainte-Laguë method]], which are more generous to small parties.<ref>Gallaher, Michael (1992). "[https://www.tcd.ie/Political_Science/staff/michael_gallagher/BJPS1992.pdf Comparing Proportional Representation Electoral Systems: Quotas, Thresholds, Paradoxes and Majorities]"</ref>

For these elections, and compared with the 2002 elections, the MPs distributed by districts were the following:<ref name="CNE">{{cite web|url=http://www.cne.pt/sites/default/files/dl/md_ar2005.pdf|title=Mapa Oficial n.º 5-A/2004|publisher=CNE - Comissão Nacional de Eleições - DR I Série-A, nº 301, 27 de Dezembro de 2004|access-date=2 December 2020}}</ref>
