Singhammer has been a member of the
Christian Social Union since 1972. He was first elected to the German
Bundestag in the
1994 federal elections, as representative of the
Munich North constituency. He initially served on the Committee on Labour and Social Affairs as well as on the Committee on Family Affairs, Senior Citizens, Women and Youth. In the negotiations to form a
coalition government following the
2013 federal elections, Singhammer was part of the CDU/CSU delegation in the working group on health policy, led by
Jens Spahn and
Karl Lauterbach. In July 2016, Singhammer announced that he would not stand in the
2017 federal elections but instead resign from active politics by the end of the parliamentary term. By late 2017, Singhammer commissioned a comprehensive report on the right of Poland to demand
reparations from Germany for
World War II. German parliamentary legal experts later found any claims related to German crimes had become unfeasible at latest in 1990 when a
treaty was signed by East and West Germany, France, the Soviet Union, the United Kingdom, and the United States ahead of
German reunification. ==Other activities==
