The past decade has been a relatively tumultuous time in Swedish parliamentary politics with minority governments, a new party challenging the status quo and ultimately the breaking of the second largest coalition in Swedish politics. The decade also saw some policy changes in parties, most strikingly the Moderate party which once an outspoken proponent of a lax immigration policy, saw a clear shift to a more restrictive policy after the 2015 refugee crisis. The first aim of this study is to explain what the shift in immigration policy looks like in terms of whether it was a positional change or a change in ideological emphasis too. By using the method of comparing manifestos the conclusion was reached that the Moderate party shifted both their positional policy and their ideological emphasis. The question of what drives political parties to change policy is a hotly debated one with a wide array of theories and perspectives contributing to the discussion. In addition this study also attempts to apply the theory first proposed by Harmel and Janda (1994) “An Integrated Theory of Party Goals and Party change” on the Moderate party to explain the driving force behind the shift in immigration policy. This was done by comparing Moderate party manifestos from the year 2006 to 2018 in three issues (immigration, private actors in the education sector and private actors in the healthcare sector) that saw the public opinion clearly shift away from the party. Mostly through the process of elimination the study concludes that the Moderate party likely shifted their position on immigration issues in order to have better chances of forming more advantageous coalitions in order to change their opposition status in the future.
