German prosecutors investigate ex-minister over leak
Former agriculture minister Hans-Peter Friedrich, a conservative, quit over accusations he leaked confidential information about a fellow lawmaker suspected of possessing child pornography.
"We have started proceedings", said a spokesman for Berlin prosecutors.
Friedrich had in October 2013 told the chairman of the Social Democrats (SPD), with whom the conservatives were in coalition talks, that the name of a then SPD lawmaker Sebastian Edathy had come up as part of an international investigation.
