The greatest part of Serbian citizens trust the Democratic Party (DS) most, while the DS' greatest opponent, the Serbian Progressive Party (SNS), is currently recording a drop in the public rating, while the number of individuals who would not give their vote to any of the candidates on the list in the next elections seems to be on constant increase, show the results of an opinion poll carried out by Ninamedia research agency, the Belgrade-based daily Press reported.

According to the results of the poll carried out in the first half of May, 21.7 per cent of interviewees would vote for the DS, while 15.6 per cent of them would vote for the SNS.

The slim majority of 51 per cent of citizens would go to polls, 38.1 per cent of voters do not know how they would place their votes, while 5.3 per cent of interviewees said that they would invalidate the ballot.

Compared to the results of the research carried out in April, the number of voters who have not made a decision about their ballots in the forthcoming elections has increased by 8.2 per cent.

In the period from April to May, the number of citizens who support the DS increased from 17.9 per cent to 21.7 per cent, while the SNS rating dropped following the strike of the party's leader Tomislav Nikolic by as much as 9 per cent, tumbling from 24.6 per cent to 15.6 per cent.

All other parties are lagging behind the country's two major parties and the poll shows that, taking into account the undecided voters, no party except the DS and the SNS would be able to exceed the 5 per cent census.

The party closest to the census is the Serbian Radical Party, since the number of citizens who support it increased from 3 per cent to 4.6 per cent in one month.

Despite its coalition with the United Serbia (JS) and the Party of United Pensioners of Serbia (PUPS), the Socialist Party of Serbia (SPS) would not be able to make it to the parliament, even if individual ratings of the three parties were added up, since the SPS-JS-PUPS coalition would win votes of only 4.3 per cent of citizens.

The DS has the greatest number of supporters in AP Vojvodina (29.9 per cent) and the majority of SNS supporters live in central Serbia, while the DS has greater support than the SNS among citizens of Belgrade.
