Bornholm currently elects two of the 179 members of the Folketing using the open party-list proportional representation electoral system.

[8][9] Only parties that reach any one of three thresholds stipulated by section 77 of the Folketing (Parliamentary) Elections Act - winning at least one constituency seat; obtaining at least the Hare quota (valid votes in province/number of constituency seats in province) in two of the three provinces; or obtaining at least 2% of the national vote - compete for compensatory seats.

[10][11] The fact that the people of Bornholm elect 2 members of parliament, even though the size of the population only justifies 1 member of Parliament has led to criticism of the electoral law being undemocratic.
