The Left Party has a number of internal caucuses, most often referred to as platforms or forums.
The Anti-capitalist Left (Antikapitalistische Linke) represents those critical of participation in coalition governments. They believe that government participation should be dependent on a set of minimum criteria (including no privatizations, no war involvement, and no cuts in social welfare spending). The grouping seeks to position the party firmly against any form of capitalism. Prominent representatives of this group are Sahra Wagenknecht, Tobias Pflüger, Cornelia Hirsch, and Ulla Jelpke.
The Communist Platform (Kommunistische Plattform, KPF) was originally formed as a tendency of the PDS. It is less critical of German Democratic Republic than other groupings, and it upholds orthodox Marxist positions. A "strategic goal" of the KPF is "building a new socialist society, using the positive experiences of real socialism and to learn from mistakes" Its primary leader is Sahra Wagenknecht, who is on the National Committee of the Left Party. The Platform had around 850 members in 2007, according to the Verfassungsschutz—around 1% of the party's national membership.
The Socialist Left (Sozialistische Linke) was formed in August 2006 and includes keynesian economics-leftists and reform communists. The group seeks to orient the party toward the labour movement. Many leaders of the Socialist Left were former members of the WASG. Socialist Left sympathizes with the Dutch Socialist Party and the Italian Communist Refoundation Party.
The Emancipatory Left (Emanzipatorische Linke, Ema.Li) is a current that endorses libertarian socialist principles. It backs a decentralized society and support social movements. Ema.Li's spokespersons are Julia Bonk (member of parliament in Saxony) and Christoph Spehr, spokesman of The Left in Bremen. Other representatives are the vice Chairwoman of the party Katja Kipping and Caren Lay.
The Reform Left Network (Netzwerk Reformlinke) was originally formed in 2003 as a tendency in the PDS. It promotes social-democratic positions and supports cooperation with the Social Democratic Party of Germany and the Alliance 90/The Greens. A prominent member of the network is Petra Pau.
The Democratic Socialist Forum (Forum demokratischer Sozialismus) is a democratic socialist faction that was originally part of the PDS. It supports participation in state coalition governments and is programmatically close to the Reform Left Network.
In addition to the main platforms, a number of far-left groups have aligned with the Left Party and its predecessors, the PDS and WASG, including Linksruck (now known as Marx21).
