She is a member of the Parliamentary Assembly of the Council of Europe.
In the circumcision debate in 2012 she strongly opted for an alternative bill to the new circumcision law § 1631d BGB. The alternative bill draft proposed to require a minimum age of 14 years for the circumcision and more specific conditions.
As the initator, she enforced a Resolution by the Parliamentary Assembly of the Council of Europe in 2013, which demands that all member states should seek dialogue with religious communities to ban circumcision and other harmful rituals for children.
