Danish Prime Minister Lars Lokke Rasmussen announced the date of parliamentary elections, June 5.
Social Democrats, Denmark's largest opposition party, leads in opinion polls and according to observers it can form a minority government that will cooperate with right-wing parties on immigration policy.
This would change the clear left- and right-wing or ‘red and blue bloc’ party politics which had been the base of Danish politics for decades.
Social Democrats leader Mette Frederiksen presented proposals last year to send "non-Western" foreigners and "non-ethnic Danes" to UN camps in Africa.
Such anti-immigrant rhetoric, first introduced by the far-right, is now commonly used by the Social Democrats and other parties.
