Parliamentary elections were held in Serbia on 24 April 2016. Initially, the election were originally due to be held by March 2018, but on 17 January 2016 Prime Minister Aleksandar Vučić called for a snap election claiming Serbia "needs four more years of stability so that it is ready to join the European Union". The elections were held simultaneously with provincial elections in Vojvodina and nationwide local elections. Voter turnout was 56%. Vučić's Serbian Progressive Party-led coalition retained its majority, winning 131 of the 250 seats. In contrast to the 2014 elections, a record-breaking seven non-minority lists passed the 5% threshold. Several parties returned to the National Assembly, including the Serbian Radical Party, the Liberal Democratic Party and the Democratic Party of Serbia, while three parties entered for the first time; the liberal Enough is Enough, the conservative Dveri (in coalition with the Democratic Party of Serbia) and the Green Party (as a Slovak ethnic minority list). Vučić announced formation of the new government by early June. He stated that the Alliance of Vojvodina Hungarians were the only certain partners in the cabinet, and remained ambiguous about the future cooperation with the Socialist Party of Serbia, the coalition partners in the previous government. After a two-month delay, Vučić announced the new cabinet on 8 August, consisting of eight old and eight new ministers, retaining the coalition with the Socialist Party. The government was approved by the National Assembly on 10 August. Electoral system The 250 members of the National Assembly are elected by proportional representation in a single nationwide constituency with a 5% electoral threshold (with the percentages calculated including the invalid and blank votes cast), although the threshold is disregarded for coalitions representing ethnic minorities. Seats are allocated using the d'Hondt method. Campaign In November 2014 Dveri and the Democratic Party of Serbia declared that they would contest the elections as the "Patriotic Bloc" alliance. In January 2015 PULS and SLS also joined the bloc. On 19 February 2016, the Party of United Pensioners of Serbia (PUPS) decided to leave the coalition with SPS, and sign an agreement with SNS, as did the SDPS. DS, SDS and the LDP agreed to form a coalition called "Democratic Serbia - DS-LDP-SDS", with Dragoljub Mićunović as the leader. However, on 28 February DS leader Bojan Pajtić said that his party would not join the SDS and the LDP in a pre-election coalition.
