Left Socialists (Danish: Venstresocialisterne) was a political party in Denmark. VS works on what it calls a 'undogmatic revolutionary and Marxist basis'.
It was formed in 1967 as a split from the Socialist People's Party (SF). VS was represented by the letter "Y" on the electoral ballots. VS members of parliament were respected and are well remembered for their principled positions and their striking personalities. The VS is most remembered for its part in the anti-nuclear movement that led to the Danish government banning nuclear energy and for its ambitious energy proposals. From 1984 to 1992 VS had a youth wing, Venstresocialisternes Ungdom.
In 1989 the Left Socialists founded the Red-Green Alliance with the Communist Party of Denmark and Socialist Workers Party to contest in elections. At its last congress in 1998 the Left Socialists transformed itself from a party to an association. Since then, VS concentrates most of its work towards building of the Red-Green Alliance. It still publishes Solidaritet (Solidarity) and maintains a website, but except for that it has little activity of its own.
