With around 6 percent of Sweden's support, according to recent polls, the Left Party fights first and foremost for a more equal society.
"In the last 30 years Sweden has got worse again," the party writes on its official website.
"Greedy companies have been allowed to control more and more. Sweden now has high unemployment, a shortage of housing, a poorer welfare services and a less equal society."
The party has made it clear that it wants to be in a government together with the Social Democrats and the Green Party, although Social Democrats opposition leader Stefan Löfven has been keeping his post-election plans close to his chest.
The issue that sets the Left Party apart from the others is its intolerance of profits in the welfare sector - a topic that party leader Jonas Sjöstedt has returned to time and time again.
"We are the only party that wants to make it impossible for private companies to make big profits from schools, healthcare and social services," the party writes on its website.
Here is The Local's guide to the party's key policies:
- More jobs through investments in infrastructure, housing, and climate issues
- Jobs or training within 90 days to unemployed people under 25
- No tax increase for low and middle income earners
- Improve opportunities for small business owners by removing their sick pay liability
