The number of political parties in Sweden that are identifying themselves as caring for the labour politics and labour workers is increasing. Due to that and the upcoming Swedish parliamentary election in September 2018, I have investigated fulfillment of election pledges within the field of labour politics during two mandate periods seen to four cases. The questions that binds this thesis together is which of the four cases that have fulfilled the highest number and the highest percentage of the studied election pledges, and to what extent, during the mandate periods of 2006 to 2010 and 2014 to the 1st of May 2018. This is being made through a quantitative literature study which applies theory consuming methods of the responsible party model and the rational choice theory.   This study concludes that the socialist party, Socialdemokraterna, is the party that have fulfilled and started the highest percentage of the studied election pledges. Seen to the number, the socialist and environmental friendly coalition, de rödgröna, had the highest full fulfillment of pledges. However, the liberal conservative coalition, Alliansen, had the highest number of half fulfilled pledges. They also had the highest number of pledges with no fulfillmet, wherease the environmental friendly party, Miljöpartiet, had the highest percentage of election pledges with no fulfillment.

There is a large part of the population today whose perception of Swedish political parties assumes a pronounced distrust. Often, this mistrust is linked to whether politicians act on the election promises made during the election campaigns. This is a view that opposition parties often encourage through negative criticism during election campaigns and media platforms. The paradox that arises then becomes markedly confusing because research actually shows that parties almost fulfill most of the election promises made.   Furthermore, a society characterized by widespread distrust of political activity risks gradually undermining the representative democracy system, which may lead to diminished democratic legitimacy. In the field of research, therefore, there is often talk of making knowledge regarding election promises more accessible to voters, who then may examine political activity more effectively themselves. The study has analyzed the Alliance's and the Social Democrats' election promise fulfillment during the mandate periods 2006-2010 and 2014-2018, through qualitative analysis of the election manifesto and data collection from the Riksdag's website. The aim was to investigate and compare which of these party organizations best achieved good representation during the alternative government periods through clear method choices that could present data in an easily accessible way.   The study arrives at a result that shows a balancing election promise fulfillment between the Alliance and the Social Democrats, with a small statistical advantage for the Alliance. It also shows how the Alliance has achieved a slightly better representation by succeeding in fulfilling more election promises in key policy areas that the party organization has given higher priority to during the election campaigns and election manifestos.
