The results are in following Denmark's elections, and the Euroskeptic and anti-immigration Danish People's Party (DPP) has won with 21.1 percent of the vote. Denmark's voting system is based on groupings of parties, called voting blocs. To form a government, a party's bloc must win an overall majority. This system worked against the Social Democratic Party, the lead party of the incumbent center-left coalition. Although it received 26.3 percent of the vote, its left-wing "red bloc" did not perform as well as the right-wing "blue bloc," in which the DPP is the highest placed.

The Danish People's Party must now decide how involved it will be in the new government. The prime minister looks set to be the head of the center-right Venstre party, which won 19.5 percent of the vote. Kristian Thulesen Dahl, the DPP chief, does not appear to be interested in taking the premiership for himself. Between 2001 and 2011, Venstre governed with a coalition that relied on the DPP for support from outside the government. From this position, the DPP was particularly effective at getting its policies passed while maintaining a level of public support of around 12 percent. The recent downfall of the Liberal Democrats in the British elections demonstrates the dangers of being the junior member of a coalition. From its outsider position, by contrast, the DPP was able to effectively distance itself from government decisions it did not support. This approach will be difficult to maintain — with such a strong electoral performance, DPP supporters may push for the party to take a more central role in governance.

However the DPP chooses to interact with the government, the party's influence will be significant — and its increased role will impact wider European trends. Recently re-elected British Prime Minister David Cameron is renegotiating the United Kingdom's relationship with Europe and will hold a public "in-out" referendum before the end of 2017. The DPP is part of the same European Conservatives and Reformists Group as Cameron's Tories in the European Parliament and is equally concerned about the erosion of national sovereignty in Europe and perceived high levels of immigration. European Parliament member and DPP vice chair Morten Messerschmidt said the party's intention is to "make Denmark into Cameron's biggest ally." Indeed, even before the election, the DPP had managed to convince Venstre, which is nominally pro-Europe, to offer its support for Cameron's renegotiation if the blue bloc won. Once the new government takes power, the United Kingdom looks set to gain a firm ally.

The United Kingdom and Denmark have voiced common concerns about European integration in the past. For example, the Danish in 1992 and the British in 1993 both voted against the Maastricht Treaty, which led to the creation of the European Union, as did a sizable portion of the United Kingdom's ruling Conservative Party. Both countries have also consistently negotiated opt-outs, most notably in the case of the eurozone. Now, there are several other countries in Northern Europe that may also support these moves. Finland's Finns Party is also a member of the European Conservatives and Reformists Group and shares the Tory and DPP sentiments about national sovereignty and immigration. The party has just entered a ruling coalition, with its leader as foreign minister. The DPP's Swedish counterpart, the Sweden Democrats, were kept out of government at the end of 2014 only because of a fragile deal between the center-right and center-left parties. This agreement could be undermined if the DPP and the Finns Party demonstrate that they are able to govern from within a coalition.

The Alternative for Germany party, another member of the European Conservatives and Reformists, is well positioned to taking advantage of German frustrations with the Greek debt situation. Although the party is currently beset with internal strife, if it emerges united it could also ally with the DPP and the Tories. Poland's Euroskeptic Law and Justice Party, also a member of the right-wing European Parliament group, won the country's presidential election last month and stands to perform strongly in general elections in October 2015. Although some of Cameron's immigration policies might be distasteful to the Polish people, a potential Law and Justice-led government in Warsaw would find common ground on reclaiming sovereignty from the European Union. With all of these likely supporters, Cameron's Conservatives and the DPP have the potential to form an alliance of Northern European parties dedicated to the repatriation of power to European countries.
