Denmark is a representative democracy with universal suffrage. Membership of the Folketing is based on proportional representation of political parties, with a 2% electoral threshold. Denmark elects 175 members to the Folketing, with Greenland and the Faroe Islands electing an additional two members each—179 members in total. Parliamentary elections are held at least every four years, but it is within the powers of the prime minister to ask the monarch to call for an election before the term has elapsed. On a vote of no confidence, the Folketing may force a single minister or an entire government to resign.
