Parliamentary elections were held in Finland on 17 April 2011 after the termination of the previous parliamentary term. Advance voting, which included voting by Finnish expatriates, was held between 6 and 12 April with a turnout of 31.2%.
The importance of the election was magnified due to Finland's capacity to influence the European Union's decision in regard to affecting a bailout for Portugal via the European Financial Stability Facility, as part of financial support systems for debt-laden European countries, and the fall of the Portuguese government. Small differences in the opinion polls for the traditional three big parties (the National Coalition Party, the Centre Party and the Social Democratic Party) and the surprising rise in support for the True Finns also electrified the atmosphere ahead of the election.
The election resulted in a breakthrough for the populist True Finns, which came head-to-head with the three big parties, while every other parliamentary party in mainland Finland, excluding Åland, lost popularity. The National Coalition Party (NCP) also ended up as the biggest party for the first time in its history. The total turnout rose to 70.5% from 67.9% in the previous election; and corruption scandals also resulted in an anti-incumbency vote. The incumbent, Centre Party-led coalition, which included the NCP, Green League and Swedish People's Party (SPP), lost its majority by two seats and their Prime Minister Mari Kiviniemi of the Centre Party signaled that her party would then sit in opposition.
The incumbent Minister of Finance Jyrki Katainen, as the leader of the biggest party in the new parliament, was tasked to form a new government. During government formation talks, the True Finns said they would withdraw if the government accepted the Portuguese bailout. Katainen then continued six-party talks that included the NCP, the SDP, the Left Alliance, Green League, Christian Democrats and the SPP. However, these negotiations ran aground on 1 June as the Social Democrats and the Left Alliance walked out of the talks due to strong differences on economic policies. Negotiations were set to continue under Katainen's proposed premiership, though the composition of the new government was not certain at the time. Due to the Green League's opposition to forming a government with the NCP, the Centre Party and the Christian Democrats, Katainen—avoiding a resultant minority government—announced on 10 June that the same six parties would return to negotiations, describing it as the "only possible coalition." On 17 June, the six parties came to an agreement on forming a coalition government, led by Katainen and consisting of 19 ministers. The ministerial portfolios were divided with the NCP and the SDP both having six ministers, while the Left Alliance, the Greens and the SPP would each have two and the Christian Democrats would have one. The six parties announced their ministers designate between 17–20 June. On 22 June the new parliament elected Jyrki Katainen as prime minister.

Background.
In June 2010, then-Prime Minister of Finland and leader of the Centre Party Matti Vanhanen said that he would be stepping down from both positions. At a party conference held between 11 and 13 June, then-Minister for Public Administration and Local Government Mari Kiviniemi was elected the new party leader. Vanhanen stepped down from the position of the prime minister a few days later and was replaced by Kiviniemi, who became the second female prime minister in Finland's history.
The incumbent government was considering proposals for a new constitution, including a phrase in the first paragraph of the third clause that would have read "Finland is a member of the European Union." It was speculated that the incumbent government could finalise a new constitution before the election but the changes to the constitution would require the support of the next parliament in order to pass.
Electoral system.
The 200 members of the parliament are elected using the proportional D'Hondt method through which voters cast their vote for a candidate of their choosing within a party list. Electoral alliances between parties were allowed but were less common for the parliamentary parties in this election as the parties were preparing for future electoral reform that would not provide for electoral alliances.
In 2011 the country was divided into 15 electoral districts. (Åland is the only single member electoral district and it also has its own party system.) The electoral districts are shown below.
Following the problem-ridden limited electronic voting experiment of the 2008 municipal elections, the Ministry of Justice announced in January 2010 that there would be no electronic voting at this time, but that the ministry would be monitoring the international arenas for development of online voting.
Campaign funding.
This was the first election since the Act on a Candidate's Election Funding came into force in May 2009, along with the 2010 amendments to the Act on Political Parties. Both laws mandate the disclosure of the sources of campaign finance and expenses. Every candidate and party as a whole must disclose their source of funding. Campaign funding may start six months before the election day and end two weeks after the election regardless of when the costs are actually paid. The candidates must file a public report with the National Audit Office detailing their sources of all contributions of over €1,500 in value raised in support of the election campaign. The funds include expenses from the candidate's own assets, loans taken out for the campaign, and contributions received by either the individual or by a group that supports the candidate. Candidates are barred from receiving anonymous contributions of over €1,500 in value.
Retiring incumbents.
Former Prime Minister Matti Vanhanen began to work as the Chief Executive of Finnish Family Firms Association and did not participate in the election.
The incumbent Speaker of Parliament Sauli Niinistö of the National Coalition Party did not run for parliament, despite receiving a record number of votes in the 2007 election. It was anticipated that he would be the National Coalition Party's presidential candidate in 2012; which he won. Overall there were 38 MPs not seeking re-election.
Competing parties.
At the time of the election there were 17 registered parties (a party has to collect signatures from at least 5,000 eligible voters in order to be accepted on the official party register, which is maintained by the Ministry of Justice). Eight of the parties were represented in the current parliament: the Centre Party, National Coalition Party (NCP), Social Democratic Party (SDP), Left Alliance, Green League, Swedish People's Party (SPP), Christian Democrats and True Finns. The MP representing Åland sits with the Swedish People's Party in the parliament.
Nine of the registered parties did not have representation in the parliament before or as a result of the elections: the Communist Party, Senior Citizens' Party, Communist Workers' Party – For Peace and Socialism, Workers Party, Independence Party, For the Poor, Pirate Party, Change 2011, and Freedom Party.
Party conferences.
The Centre Party, the National Coalition Party, the Social Democratic Party and the Green League held party conferences in May or June 2010 where they elected the party leadership for the election and approved their election manifestoes. The Left Alliance held its conference in 2009, when they elected Paavo Arhinmäki chairman after the previous chairman resigned in 2009 due to the party's poor result in the European Parliament election.
Mari Kiviniemi was elected the new leader of the Centre Party in its conference in Lahti on 12 June. The support for the Centre Party has been significantly higher in northern Finland than elsewhere: in the 2007 election the party received over 43% of the votes in both Oulu and Lapland electoral districts, compared with its nationwide support of 23.1%, while in 2003 the party's vote share in the two northernmost districts was even higher) As the top spots of the party leadership went to members from southern Finland, many of their supporters in the northern part of the country felt disenchanted; one local party chief even warned that many northern Centre Party supporters might switch sides to the True Finns.
The National Coalition Party re-elected incumbent Minister of Finance Jyrki Katainen the party leader on 12 June, amidst protests by Greenpeace activists.
The Green League held its party conference between 22 and 23 May. The Greens emphasised the importance of the environment and set same-sex marriage and increasing foreign aid as the party's objectives.
Campaign.
In what was seen to have promoted anti-incumbency, a scandal regarding campaign finance followed allegation that the Centre Party's Timo Kalli's, who was also the head of the party's parliamentary group, admission in early May 2009 that he violated the law on reporting electoral campaign financing by not disclosing financial contributions he received for his election campaign during the previous election in 2007. When the media then delved further into the issue, stories started to emerge of common practice with a multitude of MPs not disclosing their financial benefactors, a practice which was not punishable under Finnish law. The media investigations focused on a group of entrepreneurs called "Kehittyvien Maakuntien Suomi" (Finland of Developing Provinces) who financed the electoral campaigns of numerous high-profile government and opposition candidates. Further investigations revealed that many recipients of their financial support did not register or even mention the amounts they received from the group. Then Prime Minister Matti Vanhanen was at the core of the accusations after the investigations showed he had also been among the beneficiaries of the groups' financing; this was despite one of the members of the group who had planned to build the biggest shopping mall in the country received Vanhanen's support for the plans against the grain of public opinion, thus eliciting accusations that he could have been influenced by the individual. Blame was also put on the Centre Party's secretary Jarmo Korhonen. This was said to have helped the True Finns.
The European sovereign debt crisis was another important issue in the election, even more so after Portugal applied for an EU bailout on 6 April, the first day of advance voting. According to an opinion poll nearly 60% of Finns were against Finland's participation in bailing out the crisis-ridden countries. All four parties of the governing coalition (Centre Party, National Coalition Party, Green League and the Swedish People's Party) support Finland's participation in the bailout and all four opposition parties (Social Democrats, Left Alliance, Christian Democrats and the True Finns) oppose such measures. The issue helped Soini become the most visible opposition leader. Soini then also stated that his party would not join in any coalition that supports guarantees to the crisis-ridden EU countries. He said that their crises are a consequence of the EU's failure. Finance Minister Jyrki Katainen had commented that a bailout for Portugal should only happen if the Portuguese parliament passed even tougher austerity measures than the failed programme that led to an early Portuguese election: "The package must be really strict because otherwise it doesn't make any sense. The package must be harder and more comprehensive than the one the parliament voted against." Despite his comments, the National Coalition Party believed the bailout to be in Finland's interests. It, along with the Centre Party, supported the bailout under the EU's auspices, while the True Finns and the Social Democrats were opposed to it. The True Finns said that Finnish taxpayers were being unjustly burdened by "squanderers" within the eurozone and pointed out that no one aided Finland during its own financial crisis in the 1990s. "Helsingin Sanomat" read the affair as having added "confusion" and complexity to the electoral race. The effect of the Finnish election on a possible EU bailout caused concern amongst to international investors as "it is a very distinct possibility that the next government and parliament of Finland will not want to agree to the things that the current government has signed up for, namely supporting Portugal and agreeing to the permanent and temporary crisis mechanisms," as there was said to be an "even chance" of Finland blocking a bailout for Portugal as its support was crucial because it would need the unanimous support of all national governments to pass. Finland's participation was further thrown in doubt as it was the only eurozone country to require parliamentary approval of any such measure. Should a new Finnish administration opt out of the bailout, this could throw into doubt the eurozone's capacity to maintain financial stability.
Yet another important issue during the campaign was that of the languages in the country. The status of
