In foreign policy, the party is Eurosceptic,[14] being critical of the European Union and opposing Sweden’s entry into the eurozone.

Between 2014 and 2018, it supported the minority government of Social Democrats and Greens in the Riksdag, extending this cooperation to many of Sweden's counties and municipalities; and from 2018 to 2021, until the outset of the 2021 Swedish government crisis, it offered passive support to the Löfven II cabinet formed under the January Agreement, though disagreeing with some of the policies mandated by the Agreement.

It is also part of the European Left Alliance for the People and the Planet; a pan-European party that supports an alternative to capitalism.

In the upper-class neighbourhood of Stockholm, Östermalm, residents formed paramilitary structures to defend themselves from a possible armed revolution.

Almost all SSV leaders eventually returned to the Social Democrats (SAP), but the foundation was laid for a party on the left wing of the labor movement.

Höglund was displeased with developments in Moscow after the death of Vladimir Lenin, and thus he founded his own Communist Party, independent from the Comintern.

Nils Flyg, Karl Kilbom, Ture Nerman, all MPs, and the majority of the party membership, were expelled by the Comintern.

The Central Committee adopted a declaration in September 1939, which read: "The ruling cliques in England and France have, in fear of Bolshevism, in their badly hidden sympathy for Fascism, in fear of workers' power in Europe, refused to enter into an agreement with conditions acceptable to the Soviet Union to effectively crush the plans of the warmongers.

The Soviet Union has thus, in clear accordance with its consequent policy of peace, through a non-aggression pact with Germany, sought to defend the 170 million people of the first socialist state against Fascist attacks and the bottomless misery of a world war.

[32] Following orders by the German delegation in Stockholm, the Swedish government took several repressive measures against the party.

The main publications were effectively proscribed (they were banned from transportation, meaning it was illegal to carry SKP newspapers in any form of vehicle).

Key cadres of the party and youth league were detained in camps, officially as a part of their military service.

One of the financial supporters of the group behind the attack, Paul Wretlind, was a regional leader of the Liberal Party in Stockholm.

The prime minister Tage Erlander declared his intention to turn "every trade union into a battlefield against the communists".

In the municipal elections of 1968, the VPK received 3,8% of the votes, the party's worst electoral result in the post-war era.

The committee was rapidly out-manoeuvered by the United NLF Groups (DFFG), an organization led by the KFML that was actively supporting the armed struggle of the National Liberation Front of South Vietnam.

In retrospect, the main factor behind this shift was not the party itself, but the fact that the Social Democrats had moved considerably towards the right in the preceding years, which had alienated much of its traditional voter base.

The Left Democrats was later, at a meeting in Stockholm on 29 January 2006, constituted as a nationwide party with ambitions of contesting the 2006 parliamentary elections.

The parties contested the 2010 general election on a joint manifesto, but lost to the incumbent centre-right coalition The Alliance.

The party thus advocates the creation of a specific Minister of Social Equality, as well as to introduce the teaching of "feminist self-defence" in high schools.

Feminist theory has grown into the party since the 1960s, when the women's movement gained a theoretical basis beyond Marxism.

[45] The party supports a generous immigration policy, granting refugees permanent residency, and prioritizing family re-unification.
