The pre-election period was marked by speculation about the possible date of the election, potential coalitions and unification of the opposition, as well as accusations of corruption and nepotism in the government led by Prime Minister
Andrej Plenković and his changes in ministers.
Changes of ministers in the government Plenković's two governments were marked by many changes in ministerial positions, a total of 30 ministers. Of its initial lineup in 2016, only
Nina Obuljen Koržinek (
Minister of Culture and Media), the Deputy Prime Minister
Oleg Butković (
Minister of the Sea, Transport and Infrastructure), and the Deputy Prime Minister
Tomo Medved (
Minister of Croatian Veterans) remained.
The Bridge ministers
Vlaho Orepić (
Minister of the Interior),
Ante Šprlje (
Minister of Justice), and
Slaven Dobrović (
Minister of Environmental Protection and Energy) were the first to leave the
government. They were dismissed by Plenković for refusing to reject the vote of no confidence in
Zdravko Marić (
Finance Minister) requested by the opposition. Immediately afterwards, fourth The Bridge member
Ivan Kovačić (
Minister of Administration) resigned from the government, as did
Pavo Barišić (
Minister of Education) who was facing accusations of plagiarism which were later dismissed by the
University of Augsburg. Scandals occurred in 2018, which began with the Borg affair that led to the departure of Economy Minister
Martina Dalić and her replacement by
Darko Horvat, who was incarcerated in
Remetinec prison in 2022 after being charged with illegally awarding 2.6 million Kuna. More controversies occurred in 2020, with
Milan Kujundžić (
Minister of Health) leaving the government following a series of real estate scandal.
Damir Krstičević (
Minister of Defence) resigned after the crash of a military training plane in which two members of the
Croatian Air Force died near Biljana Donje near
Zadar. He was replaced by
Mario Banožić, who left after committing manslaughter while driving irresponsibly. On 28 February 2024,
Jutarnji list reported that HDZ planned to hold the General Assembly on 17 March 2024 in the
Vatroslav Lisinski Concert Hall in
Zagreb, three months before the deadline. Information subsequently began to circulate that the Parliament could be dissolved on 22 March, the last day of the 21st session of the Croatian Parliament, and the dissolution could be voted on. On 8 March, Plenković confirmed the dissolution of parliament on 14 March. On 14 March 2024, the Parliament unanimously voted to dissolve itself, without specifying a date for the election. The following day, president
Zoran Milanović announced that elections will be held on 17 April. For the first time, the election will be held on a Wednesday, while the
2000 Croatian parliamentary election was held on a Monday.
Pre-election events The first pre-election coalition was agreed by
The Bridge and
Croatian Sovereignists on 8 July 2023, with an open spot for other parties ranging from the center to the right including the
Homeland Movement. Ivan Penava (DP) did not decline the possibility but instead called for Most to join a coalition with DP. After that DP entered a short-lived alliance with the
Croatian Democratic Peasant Party on 16 December 2023. On 27 March 2024, DP concluded an agreement with
Law and Justice, a party which emerged following the unification of
The Key of Croatia,
Let's Change Croatia and Independent list of
Mislav Kolakušić. On the other hand, Most and HS decided to enlarge coalition with the
Independent Youth List (NLM) on 22 March 2024. On 28 July 2023, a coalition was agreed between two liberal regional parties, the
Istrian Democratic Assembly and the
Alliance of Primorje-Gorski Kotar, with a main goal to represent
Istria and
Kvarner in
VII and
VIII electoral districts. The coalition will also contest the 2024 European Parliament elections. Two more liberal parties,
Focus and the
People's Party – Reformists announced their cooperation on 10 November 2023. The leader of the Reformists
Radimir Čačić said that with a high level of certainty they expect a large expansion of this cooperation with parties close to them, who believe that Croatia is institutionally and as a society trapped by the HDZ, and that this should be stopped and space should be opened for a different, much more modern, more liberal Croatia. Finally two groups made one single alliance on 9 December 2023. Four party leaders: Davor Nađi (Focus), Dalibor Paus (IDS), Radimir Čačić (NS-R) and Darijo Vasilić (PGS) pointed out that they are running against the HDZ and that after the elections they will not participate in the government with the HDZ, although Čačić did not rule out the possibility of supporting a
minority government. On 5 March 2024, the coalition was formally constituted under the name "For Better Croatia". The coalition later collapsed after Focus decided to ally with the
Republic party of
Damir Vanđelić, while the Reformists still partnered with IDS and PGS in VII. and VIII constituencies and with the
Rivers of Justice coalition in other constutuencues.
Social Democratic Party dissidents led by Davorko Vidović as leader of
Social Democrats made an agreement with the
Croatian Peasant Party on 7 October 2023, creating the "
Our Croatia" () coalition. Ten days later
Croatian Labourists – Labour Party joined coalition emphasizing this is just continued cooperation and trust. On 2 March 2024, the
Democrats joined the coalition, claiming that they recognized the great potential for positive change as well as the courage and ability to gather broadly on the left and center. HSS left the coalition on 5 March 2024 and joined the Rivers of Justice on 22 March 2024. On 27 March 2024 "Our Croatia" announced a deal with the IDS, PGS and the
NPS in III, VII and VIII electoral districts. The most anticipated coalition of the 2024 election was an alliance of the main opposition party
Social Democratic Party of Croatia and left wing contender
We Can! (Možemo!). Such an idea was seen as probable because of similar policies of the parties. We Can! announced on 27 June 2023 that it would run separately, leaving the possibility after the election to form a government with parties of the center to the left, including the SDP. On 1 March 2024,
Sandra Benčić (We Can!) announced the start of negotiations with the SDP on a "dotted coalition", which means a coalition in constituencies where they do not have enough support individually. In that case, the coalition would be implemented in IV., V., VII. and IX. electoral unit, while in other units the parties would go separately. On 22 March 2024 Možemo and SDP announced that an agreement was not reached, which means that they will go separately in all constituencies. On 17 February 2024, members of the left-liberal opposition held a
protest under the name "Enough! Let's Go to the Elections!" (). The protest was organized by SDP, We Can!,
Centre, IDS, HSS and
RF, Focus, SD, NS-Reformists,
GLAS, and
SsIP. The reason for the protest was the appointment of Judge Ivan Turudić as the
Attorney General. The day before, the same parties submitted a request for the dissolution of parliament and the holding of early elections. Most and HS joined them with signatures even if they did not participate in the protests. The next protest was held on 23 March 2024 simultaneously in
Zagreb,
Split,
Rijeka,
Osijek and
Varaždin. On 5 March 2024, a large left-liberal future coalition named For a Better Croatia was announced after an inter-party meeting. The coalition will be led by the SDP with
Peđa Grbin as prime ministerial candidate and will include Focus, NS R, PGS, IDS, Centre, HSS, Glas, RF, and SsIP
. On 17 March, Grbin announced that the
Workers' Front would not be part of the coalition, while the
Istrian Democratic Assembly,
Alliance of Primorje-Gorski Kotar and
Fokus left the coalition on 19 March, citing Milanović's candidacy, which is not in accordance with the law, as the reason. After the collapse of the coalition, the remaining parties reached an agreement on going to the elections under the
Rivers of Justice coalition. Hours after announcing the election date on 15 March, President
Zoran Milanović announced at a press conference that he would be the SDP's candidate for prime minister in the elections, during which he would run against incumbent prime minister
Andrej Plenković in
electoral district I. On 18 March, the
Constitutional Court ruled that Milanović may not be a candidate nor could he actively participate in support of the SDP during the election campaign, unless he resigns from the
presidency of Croatia. In response, Milanović described the ruling as "done in a gangster way". Ahead of the election, researchers from the
Faculty of Political Science of
University of Zagreb have developed an online electoral compass test in cooperation with
Kieskompas, which positions the main political parties and the user, based on a set of questions, on the
political spectrum. ==Electoral system==
