In Sweden, political parties have played a key role in representation and integration in its parliamentary democracy. The parties represent the social groups along professions and political thoughts and they generally act rationally in order to make consensus. However, the situation has gradually changed since the 1990s. The tendency of earlier majority building, which was triggered by the budgetary process reform, ended up in the confrontation between pre-electoral coalitions on the left and right. That results in voters choosing from between only two alternatives, although their interests are more diverse than ever before. On the other hand, a right-wing populist party which criticises the established parties’ immigration policy has gained power to the point of influencing national politics. There is no possibility that Sweden faces a crisis of political integration in near future, since the basic political institutions have enough support. However the country has reached an important phase in which the abilities of the parties to coordinate and provide representation is now questioned.
