The UK’s Independent newspaper says the British embassy in Berlin may house a “top-secret listening post”. It cites leaked US National Security Agency (NSA) documents suggesting the UK could be using hi-tech equipment housed on the embassy roof. Any such activity would be against international law, Berlin says, according to the BBC. A spokesman for David Cameron said the prime minister had not spoken to Chancellor Angela Merkel about the spying allegations and there were no plans for a conversation, although their relationship was “excellent”. He refused to comment on security issues but said Britain’s intelligence services operated under a “strong and clear legal framework”.
