This thesis compares political participation by the public through the Swedish Parliamentary Ombudsman (PO) and the German Petitions Committee of the Bundestag (PC). Through studies of literature and statistics I examine how citizens can participate through the institutions, how frequently they do and the likelihood of sparking a debate while participating. Using media theories as well as theories of participatory and representative democracy I study how citizens can use these institutions for purposes of control and proposition. Both institutions deal with complaints but the PC also deals with propositions for legislation, making the institution more versatile. The PO deals with more cases than the PC and has more far-reaching competences and areas of inspection, although neither institution has binding decisions. Thus the direct advantage for citizens using the institutions is the chance of reaching out to media and the public through freedom of information laws and the German online petition forum. The PC to a larger extent fits the representative model while the PO in some respects is more a legal than a political institution, being managed by lawyers instead of MPs. Neither institution meets the ideals of participatory politics although the German official petition is closer to it.
