A black politician campaigning in eastern Germany has become the victim of a racist campaign by a far-right party. The National Democratic Party of Germany (NPD) says it is trying to persuade Zeca Schall, a German citizen who came from Angola 21 years ago, to leave the country. Schall is a member of the Christian Democratic Union, the party led by German Chancellor Angela Merkel, and has been named as a CDU expert for the integration of minorities.
