This thesis aims to study the indirect effects of the Europeanization on national parties and the presence of an established national opposition towards the European Union (EU) and its effects in Sweden, as a result of the so-called conflict of Vaxholm.

The questions asked were whether or not it existed an established national opposition towards the EU, and if so, what the opposition consists of substantially. The research method, which was used, is a quantified text analysis on the chamber debates of the Swedish Riksdag and the party congresses of Socialdemokraterna. The study shows that there is an ambivalent opposition towards the EU and its effects in the aftermath of the conflict of Vaxholm.  Socialdemokraterna presented resistance, but did not manage to present apparent alternatives, which left the party with a rather indistinctive opposition. In contrast to the right-wing party, the left-wing party had some profound difficulties in positioning itself in the new and globalized economy. I therefore suggest, that it might be more providing and exhaustive to introduce Azmanova’s ideal-type analysis, which instead of positing parties on a left-right continuum, posit parties after respective party’s opinions concerning the risks or opportunities which the EU and the internal market’s effects.
