Die Linke is a German political party. It is a direct descendant of the former East German Communist Party.
Germany operates a system of "Verfassungsschutz" (Protection of the Constitution) at both federal level (Bundesamt für Verfassungsschutz, BfV) and state level (Landesbehörden für Verfassungsschutz, LfV), which carries out domestic surveillance of actual and suspected activities which may threaten the "free and democratic basic order" ("freiheitlich-demokratische Grundordnung") at the core of the German constitution. Die Linke, including one third of its members of parliament,  and some of its caucuses remain under observation by the BfV, listed in the annual Verfassungsschutzbericht under the heading "left-extremist tendencies and suspected cases". The 2007 report cites as evidence of the party's "extremism" Lothar Bisky's June 2007 statement that democratic socialism remains the party's goal: "We also still discuss the change of property and power relations [...]. We question the system." However, the report notes that in practice the parliamentary party appears as to act as a "reform-oriented" left force. In addition, the report cites "openly extremist groupings" within the party, notably the Marxist–Leninist Communist Platform, which in Sahra Wagenknecht has a representative on the 44-member Left Party executive. , Federal Ministry of the Interior. One former Bundestag deputy, Bodo Ramelow, was under BfV surveillance until a court decision in January 2008 that the observation was illegal. 
The Left is also under observation by four western CDU/CSU-governed states, where the party in its entirety is considered to be extremist (Lower Saxony, Hesse, Baden-Württemberg and Bavaria). Saarland ceased observation of The Left in January 2008. By contrast, in the five eastern states, The Left is not under surveillance, with the local LfVs seeing no indication of anti-constitutional behaviour of the party as a whole. However, the small "Communist Platform"—a hardline communist minority faction within the party—is under observation in three eastern states.
In January 2012, it became known that more than one third of the party's MPs were observed by the federal Verfassungsschutz due to suspected extremist views. . This was ruled to be unconstitutional by the BVerfG in 2013. Subsequently, Federal Minister of the interior Thomas de Maizière declared in 2014 that no Bundestag members of Die Linke would be under surveillance by the BfV from then on, even if they are members of the Communist Platform or comparable extreme Left factions.
