“Parliamentary supervisory committee” whose eleven Bundestag members are said to supervise Germany’s intelligence agencies Bundesnachrichtendienst, Militärischer Abschirmdienst and federal Verfassungsschutz. The P.K.G. is a German parliamentary committee presumably similar to e.g. the U.S. Senate Intelligence Committee. Its meetings are secret, held in a supposedly unsnoopable room, and its members cannot discuss what they learn, even with other Bundestag members.
This committee is the nominal control of Germany’s intelligence agencies. Spiegel.de wrote there can be disagreement between the eleven committee members and the intelligence agencies about what is worth reporting to the committee about the activities of the agencies’ tens of thousands of employees, quoting P.K.G. member the excellent Christian Ströbele (Green party) as saying in frustration “How are we supposed to control the secret services when we get no information?”
Update on 10 Jul 2014: Clemens Binninger (C.D.U.), a former policeman, is apparently chairing the PKG.
