MI6 has initiated a probe after former German intelligence chief August Hanning was arrested on charges including treason and espionage. Hanning ran Germany’s BND agency from 1998 to 2005 and is accused of leaking state secrets that could have compromised British intelligence. Prosecutors claim he obtained around 2,000 top-secret documents, potentially endangering sources and undermining security across Western allies. This has led MI6 and GCHQ to conduct a thorough review of shared sensitive information with European partners during Hanning’s tenure.

Story summary
On October 3, August Hanning, former head of Germany’s Federal Intelligence Service (BND) from December 1998 to November 2005, was arrested on suspicion of espionage and treason. Arrested alongside him in southern Germany was his former aide, identified as Manfred D., who is accused of aiding the alleged crimes. Prosecutors suspect Hanning passed approximately 2,000 classified documents to a foreign intelligence service via Manfred D over many years. The identity of the foreign power involved remains undisclosed. Searches were conducted at both men’s premises in different locations within Germany. This arrest was triggered by investigations into a separate case involving Christina Block, whose children were allegedly kidnapped in 2023. German officials emphasized that such breaches will not be tolerated, highlighting the seriousness of the allegations against Hanning and Manfred D.
