The unicameral, 386-member National Assembly, the highest organ of state authority, initiates and approves legislation sponsored by the prime minister. A party had to win at least 5% of the national vote to form a parliamentary faction. The National Assembly had 386 members, elected for a four-year term: 176 members in single-seat constituencies, 152 by proportional representation in multi-seat constituencies and 58 members to realize proportional representation. The election took over two days. On 9 April elections took place in every constituency, both single-seat and multi-seat. In order to get elected into a single-seat constituency, a candidate needs to receive more than 50% of the vote; in the 2006 elections, the victor received more than 50% of the vote in 66 of the 176 single-seat constituencies. There will be another election in the remaining 110 single-seat constituencies in the 2nd round, in which all but the top three candidates from the 1st round are excluded. Usually parties form alliances between the two rounds and withdraw many of their 3rd place candidates and call for supporting the allied party so the winning candidate of the 2nd round will receive more than 50% of the vote. However, this process is not automatic; it is grounded by negotiations. The multi-seat elections also took place during the first round of voting. 146 of the 152 seats were filled using proportional representation. The remaining 6 were added to the national list. The country was divided into 20 regions for the multi-seat elections with varying numbers of members per region. Where a party won more members in a regional than it merited, the surplus votes were deducted from the total it received in the second round. Correspondingly, a party that received fewer seats than it merited had the shortfall votes added to its total in the second round. A further 58 extra members were elected using a national list in order to achieve a more proportional result. Before the election the parties needed to be registered by the National Electoral Office. After registration the parties had the right to collect references. Each candidate had to collect 750 references in their district. If one party collected the required number in two districts in a county, then it could present a list in regional constituencies. If a party had at least seven regional lists, it could present a national compensation list. 17 March was the last day when a party could be registered and a list or a candidate could be registered. By 28 February, 49 parties had sought registration, and 45 were registered by the National Electoral Office.
Campaign
On 10 April the two parties of the governing coalition announced their alliance for the second round. The Socialist Party withdrew three of their candidates in favour of the Alliance one, and the Alliance withdrew their remaining 55 candidates, and called on its voters to support the Socialists. The leaders of the two parties ran a common campaign between the two rounds. The opposition was not united. The Hungarian Democratic Forum which hit the 5% threshold contrary to the polls and expectations made it clear that they would not support Viktor Orbán's Fidesz party. Orbán tried to get their support by declaring that he resigned from Prime Minister candidacy, and sought a compromise candidate, Péter Ákos Bod, but the MDF held to their independency; thus they did not withdraw their 3rd place candidates. However, some MDF candidates did not agree with this, and withdrew in favour of Fidesz.
