BND leak arrests prompt allied checks

German federal prosecutors allege that an aide in the office of successive BND presidents passed nearly 2,000 internal documents to August Hanning, up to June 2022 (Federal prosecutors' statement). Hanning once ran the BND, Germany's foreign intelligence service, and investigators found the trail by chance in an unrelated case. Prosecutors allege some of the material fed information Hanning supplied to one foreign service, but they cannot confirm that a separate analysis ever reached another (Federal prosecutors' statement).

A paid channel out of the president's office

The aide, identified as Manfred D., was office manager to several BND presidents from March 2012 until March 2026 (Federal prosecutors' statement). Federal prosecutors announced his arrest, and Hanning's, on 6 October (AP).

Prosecutors suspect the two men agreed that the aide would keep supplying Hanning with valuable BND material for payment. Hanning would use it in the consultancy he set up after leaving government (Federal prosecutors' statement). The official account names no client and gives no payment amount. Hanning and his lawyers deny the allegations (The Guardian).

Among the files, prosecutors say, were papers preparing agency chiefs for regular intelligence briefings at the Chancellery, the chancellor's office (Federal prosecutors' statement). Those papers show what BND leaders judged important enough to put before the head of government. They reveal the agency's priorities as well as its findings.

The case surfaced by accident, not through the BND's own controls. Hamburg prosecutors searched Hanning's premises in September 2025 during an unrelated investigation (Federal prosecutors' statement). What they found was later handed to federal prosecutors, who built the case behind this week's arrests.

Two foreign contacts, one still unconfirmed

Prosecutors describe two contacts with foreign intelligence and keep them separate. In the first, Hanning allegedly used the leaked files to write an analysis for an employee of a foreign service. Prosecutors say they cannot confirm it ever arrived (Federal prosecutors' statement).

That uncertainty explains part of the charge sheet. The suspected offences include attempted treason, and an attempt charge covers what Hanning allegedly set out to do. It does not establish that the analysis reached anyone abroad.

The second allegation goes further. Prosecutors say Hanning supplied political information over several years to a member of another state's intelligence service, drawing partly on the aide's documents (Federal prosecutors' statement). They also suspect him of acting for a foreign intelligence service. Neither country is named.

Azerbaijan entered the story through journalism. Der Spiegel reported that investigators were examining a link to an Azerbaijani operative for whom the analysis was intended (WELT). Federal prosecutors declined to comment on that report (Reuters).

WELT reports allies are checking their files

The worry abroad comes from how intelligence sharing works. Partners pass material to the BND on the understanding that it stays under German control. Reuters, citing Süddeutsche Zeitung, reported that the files included material on Iran's nuclear programme, the Russian military and information classified by allied services (Reuters).

WELT reported that MI6 (Britain's foreign intelligence service), GCHQ (its electronic eavesdropping agency) and several US agencies were reviewing what they had shared with Berlin (WELT). The paper also quoted former MI6 officer Matthew Dunn, who said he would be very surprised if relations with the BND suffered. No public account has yet identified a specific British or American document among the seized files.

Two separate jobs now run side by side. Prosecutors must prove the alleged crimes. The BND and its partners must work out what may have been exposed, and to whom. Green MP Konstantin von Notz, who sits on the Bundestag's intelligence oversight panel, urged the government to establish the damage quickly. BND president Martin Jäger said the agency had opened extensive internal inquiries (Tagesschau).

If prosecutors prove the transfers, sensitive BND material left the office of successive chiefs for years. An unrelated search, not the agency's own checks, would then be what brought it to light. A trial can settle the crimes. It cannot tell London or Washington which of their material sat in those files, and that answer is Jäger's to give.
