Dietmar Gerhard Bartsch is a German politician, former Federal Whip of the Party of Democratic Socialism and The Left and member of the Bundestag. He is married and has two children. Since October 2015, Bartsch has served as the co-leader of Die Linke's parliamentary group, a position he holds with Amira Mohamed Ali. Bartsch represents the moderate, reformist wing of the party.
In 1977, Bartsch became a member of the Socialist Unity Party, the GDR's ruling party, co-founding the Committee of Young Comrades in 1989. Following German reunification, Bartsch served as the Party of Democratic Socialism's Federal Treasurer and was later elected federal whip. In 2002, he ran as one of four leading candidates for the PDS in the general elections. After the party failed to overcome the constitutionally-defined 5-percent-clause, sending only two representatives to the Bundestag, Bartsch's political rivals asked for his resignation as federal whip. After declining to stand for re-selection as whip in 2002, he was nominated federal whip by PDS party chairmanLothar Bisky in 2005, and elected into office the following December. After the party`s transformation from The PDS into The Left, Bartsch continued leading the party in his role as federal whip. He managed the party's 2009 general election campaign, during which The Left achieved a result of 11.9% nationwide. In early January 2010, Bartsch was accused by Gregor Gysi, at the time parliamentary leader of The Left, to have harmed party chairman Oskar Lafontaine through specific statements to the German news magazineDer Spiegel. Bartsch denied this and allegations of disloyalty as well as rejecting speculation that he considered himself Lafontaine's replacement. Although he remained the whip following this incident, Bartsch declined to run for this office again in 2010. In January 2010, Bartsch was named deputy chairman of The Left's parliamentary group in the Bundestag. His used this position to focus on national budget and finances. In August 2011, he distanced himself from a congratulatory letter that two members of The Left had sent the former Cuban PresidentFidel Castro for his birthday. After some members of The Left boycotted a minute of silence for the casualties at the Berlin Wall, Bartsch suggested proponents of the Berlin Wall leave the party. Bartsch declared his intention to run for party chairman in late 2011. At the annual party convention of The Left in June 2012, Bartsch lost to union-backed candidate Bernd Riexinger from Baden-Württemberg, a close ally to former party chairman Lafontaine.
