Allied spy services review their secrets after Hanning’s arrest

European intelligence services began checking the exposure of secrets shared with Germany after the arrest of former BND president August Hanning, Reuters reported on October 8. The review widened a German criminal investigation into a question for allied agencies: what information might have travelled beyond the officials authorised to receive it?

Federal prosecutors arrested Hanning and a former senior aide, identified as Manfred D., on October 6. Their statement alleges a paid arrangement beginning around spring 2010, under which the aide supplied BND information for use in Hanning’s private consultancy. Investigators say nearly 2,000 documents changed hands through June 2022, including classified material prepared for the service’s leadership.

The alleged collection reached into preparations for intelligence situation meetings at the federal chancellery. Prosecutors say Hanning used classified information to prepare an analysis for a foreign intelligence representative. They expressly leave one crucial point unresolved: whether that analysis reached its intended recipient. They separately allege that he supplied political information over several years to someone from another state intelligence service.

Reuters based its account of the allied response on interviews with intelligence officials. One European official described reviews of information previously passed to Germany; another allied official said their own service was assessing damage. Those accounts establish that partners were checking their exposure. They do not establish that all the material under review was disclosed abroad.

Hanning denies wrongdoing. AP reported on October 7 that his lawyer acknowledged possession of confidential documents while rejecting allegations that he harmed Germany or paid for them. The lawyer said his client was being wrongfully prosecuted. AP also reported that an investigating judge ordered both suspects held in pretrial detention that day. That was an investigative measure, not a conviction.

The inquiry reaches across successive generations of BND leadership. Hanning headed the service from December 1998 until November 2005. Prosecutors say Manfred D., once his office chief, later served several subsequent presidents until March 2026. The alleged source of documents therefore occupied a position close to the agency’s leadership long after Hanning moved into private work.

The case surfaced through a different investigation. Prosecutors say material found during a September 2025 search connected to the Christina Block case was referred to federal authorities in May 2026. The BND and federal criminal police are cooperating in the resulting inquiry. Reuters reported that BND chief Martin Jaeger said internal investigations began when suspicions emerged.

The government promised investigators support, while its spokesperson cautioned that findings should come before decisions about changes to the agencies. Parliamentary critics have meanwhile pressed for tighter rules on the private work of former intelligence officials. The immediate test remains evidential: reconstructing which documents were obtained, which were used, and whether any alleged transfer breached the trust on which Germany’s intelligence partnerships depend.
