After a time during which Momper was exclusively concerned in politics, from 1992 to 1993 he was the director of the Dr. Elling GmbH. Since August 1993 he has been managing partner of Momper Entwicklungsgesellschaft mbH in Berlin. Critics and politicians of other parties have repeatedly criticised him over the links between his political and business activities,[1] for example when he advised the IKEA group about its plans to establish itself in the East of Berlin.[2][3]
