According to the latest polls, published June 17, the country’s ruling center-left Social Democrats party, led by current Prime Minister Helle Thorning-Schmidt, is supported by 24.5 percent of respondents.
The ruling party will have a tight race with its main rival center-right Liberal Party of Denmark, with the former country's leader Lars Lokke Rasmussen at the head, projected to have the support of 20.6 percent of the voters.
The two traditional parties are under pressure from the right-wing Danish People’s Party (DPP), which could join the front-runners with a potential 18 percent of the vote, compared with 12 percent received in the 2011 election.
DPP has been gaining ground recently. Last year, it won the elections to the European Parliament in Denmark and secured four seats.
The DPP calls for a "closed-door" immigration policy, including reestablishing its border with Germany to control migration flows, limiting social benefits for migrants and holding a referendum on Denmark's exit from the European Union.
On Tuesday, the party joined a far-right coalition in European Parliament, comprising a number of increasingly popular right-wing eurosceptic groups, such as the French National Front, Austria’s Freedom Party and the Italian Northern League.
