The Independent reports: Concerns were raised tonight that Britain operates a top-secret listening post from its Berlin embassy to eavesdrop on the seat of German power.

Documents leaked by the US National Security Agency whistleblower Edward Snowden show that GCHQ is, together with the US and other key partners, operating a network of electronic spy posts from diplomatic buildings around the world, which intercept data in host nations.

An American intercept “nest” on top of its embassy in Berlin – less than 150 metres from Britain’s own diplomatic mission – is believed to have been shut down last week as the US scrambled to limit the damage from revelations that it listened to mobile phone calls made by Chancellor Angela Merkel.

But the NSA documents, in conjunction with aerial photographs and information about past spying activities in Germany, suggest that Britain is operating its own covert listening station within a stone’s throw of the Bundestag, Germany’s parliament, and Ms Merkel’s offices in the Chancellery, using hi-tech equipment housed on the embassy roof.

The potentially toxic allegation that Britain has a listening station in the capital of a close European Union ally will test relations between London and Berlin only days after the row between Germany and the US about its own clandestine activities.
