Finally, reference should be made to an interesting approach that has been used for several years in the Scandinavian countries, which consists of retaining a certain number of seats to be apportioned nationally to compensate for any disproportion resulting from election results. The higher the percentage of such seats, the easier it becomes to secure national proportional representation. The figure is low in Norway (5% or 8 out of 169), higher in Sweden (11% or 39 out of 349) and Iceland (14% or 9 out of 63) and highest in Denmark (23% or 40 out of 175). In these last three countries it is therefore possible to achieve almost perfect proportional representation. For example, in the 2007 Danish elections, the gap between a party's percentage vote and its percentage of seats was never more than 0.4%. Since one seat is 0.57% of the total this means that each party had exactly the number of seats to which it was entitled. The gaps were equally small in Sweden, and in Iceland, where in 1999 for example it was non-existent.
