Vlatko Ratković

Ratković sought election to the Assembly of Vojvodina in the 2004 provincial election in the single-member Ruma constituency. He was defeated in the second round of voting by Srđan Nikolić of the Serbian Radical Party.

Ratković received the 197th position on the DS's electoral list in the 2007 Serbian parliamentary election.^[3] The list won sixty-four seats. He was not initially included in his party's assembly delegation, but he received a mandate on 22 May 2007 as the replacement for another party member.^[4] (From 2000 to 2011, parliamentary mandates were awarded to sponsoring parties or coalitions rather than to individual candidates, and the mandates were often distributed out of numerical order. Ratković's position on the list had no bearing on whether – or when – he received a mandate.)^[5] The DS formed an unstable coalition government with the rival Democratic Party of Serbia (Demokratska stranka Srbije, DSS) after the election, and Ratković served as a supporter of the ministry.

The DS–DSS coalition fell apart in early 2008, and new elections were called. Ratković received the 184th position on the DS's For a European Serbia coalition list and was selected for a second term in the assembly when it won 102 seats.^[6][7] The election did not produce a clear winner; after extended negotiations, the For a European Serbia alliance formed a new coalition government with the Socialist Party of Serbia, and Ratković again served on the government side.

Ratković chaired the legislative committee in this sitting of parliament and in this capacity played a key role in passing the Statute of the Autonomous Province of Vojvodina.^[8] He defended the provincial constitution against charges that it was a separatist document in 2011, arguing that it was fully consistent with the Constitution of Serbia.^[9] In January 2012, he said that a central electronic database of Serbian law should be available within two years.^[10]

Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists. Ratković received the ninety-seventh position on the DS's Choice for a Better Life list in the 2012 parliamentary election; the list won sixty-seven mandates, and he was not re-elected.^[11] He was subsequently appointed as assistant to the provincial secretary for energy and resources in the government of Vojvodina.

The Democratic Party experienced a serious split in early 2014, with Boris Tadić setting up a breakaway group initially called the New Democratic Party. Ratković sided with Tadić and was accordingly dismissed from his government position on 6 February 2014; this decision was condemned by the new party.^[12][13] Tadić's party contested the 2014 parliamentary election in a fusion with the Greens of Serbia and in alliance with other parties. Ratković received the forty-first position on their electoral list; the list won eighteen mandates, and he was not returned.^[14] The New Democratic Party was reconstituted as the SDS later in the year.

For the 2016 parliamentary election, the SDS ran in an alliance with the Liberal Democratic Party and the League of Social Democrats of Vojvodina. Ratković received the sixty-seventh position on their combined list and was again not returned when it won only thirteen seats.^[15]
