The Landtag of Thuringia is the state diet of the German federal state of Thuringia. It convenes in Erfurt and currently consists of 91 members of five Parties. Controversially in December 2014, the Landtag elected first ever Left Party Minister-President, Bodo Ramelow. The Left Party is seen as the successor to the Socialist Unity Party (SED) that ruled former East Germany. Ramelow heads a left-leaning coalition consisting of his Left Party, the Social Democratic Party (SPD) and the Greens, a so-called "red-red-green" coalition.
