Early life

Petrov was born in Metković to locksmith Jakov, and Marija Petrov, a bookkeeper. He has an elder sister, Nikolina, and two younger brothers, Branimir and Ivan.^[4] Petrov attended elementary school in his hometown and high school (classical Christian gymnasium) in Sinj. At the age of 14 he decided to join the Franciscan order, but eventually changed his mind.^[5]

Petrov graduated from the Medical Faculty of the University of Mostar in Bosnia and Herzegovina, and specialized psychiatry in the Psychiatric Hospital Vrapče in Zagreb, after which he worked as a psychiatrist at the University Clinical Hospital in Mostar.^[3][6]

Family

He is married to Maša Petrov, a primary school teacher, with whom he has three sons: Jakov, Dominik, and Andrija.

2015 parliamentary election

For the 2015 parliamentary election, Petrov's Most party went national and was joined by independent local politicians from other parts of the country. Led by Petrov, the party campaigned for fiscal responsibility, reduction of government spending and public debt, tax cuts, reforms in the public sector and the reduction of administrative divisions in Croatia.^[12][13]

Petrov's party turned out the surprise of the election, with 13.17% of the votes and 19 seats in the Croatian Parliament. The party had a crucial role in forming the new government and started negotiations with the ruling centre-left Croatia is Growing coalition, centred around the Social Democratic Party (SDP), and the opposition centre-right Patriotic Coalition, centred around the Croatian Democratic Union (HDZ).^[14] Members of the party said that they won’t join any of the two coalitions in forming the new government unless their reform agenda is adopted.^[15] After more than 40 days of negotiations and numerous twists, Most decided to give its support to a government led by the HDZ, giving them a slim majority of 78 seats. They nominated the Croatian Canadian businessman Tihomir Orešković to be the next Prime Minister.^[16][17]

Deputy Prime Minister (2016)

The new government was approved by the Sabor on 22 January 2016. Petrov was named Deputy Prime Minister.^[18][19] Along with Petrov, six ministers in the government were nominated by Most.^[20]

In February, the Most party prepared amendments for reducing benefits of members of the parliament, but the bill was stopped and did not reach voting in the Sabor. The party accused HDZ and SDP for blocking the bill.^[21]

In March, Petrov and his party announced amendments to the law regulating the rights of former presidents of Croatia that would rescind the Office of the Former President. This move revoked the entitlements of former president Stjepan Mesić, who criticized the move, and saved around 600,000 HRK to the government budget.^[22] In the same month, Petrov started negotiations with labour union representatives over a 6 percent wage increase for public sector workers, as GDP grew over 2% for two consecutive quarters. The wage rise was signed in 2009 by the government of Ivo Sanader with labour unions. The government had not planned funds for the wage increase in the 2016 budget and wanted to negotiate new terms of the contract, as there was no money for its implementation.^[23]

Relations between Most and the Patriotic Coalition have long been strained and continued to deteriorate in May. Members of HDZ started talking about reshuffling the government.^[24] After it was revealed that the wife of Tomislav Karamarko had business with the consultant of Hungarian oil company MOL, Petrov and his party called for Karamarko to resign due to political responsibility. A vote of no confidence was started by SDP in the Sabor, which was backed by ministers and MPs from the Most party.^[25][26] After Karamarko refused to step down, Petrov said that he and ministers from his party are ready to resign if Karamarko remained in the government, adding that "an individual should never be above the state".^[27] On 3 June, in an attempt at a compromise solution, Prime Minister Tihomir Orešković called on Petrov and Karamarko to resign for the sake of stability of the country. Orešković said that their relations have become a burden for the government. Petrov responded that he is ready to step down if it will help stabilise the situation in the country,^[28] while Karamarko refused to resign and stressed out that Orešković no longer has the support of HDZ.^[29] A vote of no confidence in the Prime Minister was initiated by HDZ. Petrov's party continued to support Orešković and asked for the resignation of Karamarko.^[30][31] On 16 June the confidence vote took place in the Parliament that resulted in the fall of Orešković's government by a vote of 125 MPs in favour, 15 against and 2 abstentions. Both HDZ and most of the opposition voted in favour, while the Bridge of Independent Lists voted against.^[32]

Speaker of Parliament (2016–2017)

Petrov was elected as the 11th Speaker of the Croatian Parliament on 14 October 2016 with 132 members of Parliament voting in favor, 1 against and 12 abstaining. Having taken office two days before his 37th birthday, Petrov became the youngest person ever to hold the position of the speaker. As per a post-election agreement between Petrov's Bridge of Independent Lists party and the Croatian Democratic Union (HDZ) led by Prime Minister Andrej Plenković, Petrov was due to serve as speaker for a 2-year period and would thereafter have been replaced by speaker from the HDZ, presumably the party's general secretary and former foreign minister Gordan Jandroković.^[33] Petrov resigned from office on 4 May 2017 amidst a government crisis which began on 27 April 2017 when Prime Minister Plenković removed three government ministers supported by Petrov's Most party and escalated further to a point where Plenković's Croatian Democratic Union began to gather signatures for Petrov's removal from office via no confidence vote. Croatian Parliament formally dismissed him from his position as speaker on 5 May 2017. Petrov remains a member of the Parliament. He was succeeded as speaker by the former foreign minister and deputy prime minister Gordan Jandroković on 5 May 2017.
