German police arrested a British diplomat in Berlin on suspicion of passing documents to Russian intelligence. The arrest has been confirmed in Scotland Yard.

Russian foreign intelligence under Sergei Naryshkin is one public failure after another. Perhaps, Naryshkin should pay more attention to his duties instead of swimming in private pools of his Azerbaijani friends in Moscow or writing funny articles.

This failure of Russian intelligence has a more interesting dimension though. Angela Merkel, who has closer contacts with Putin than any other European leader, is leaving her office after decades of serving as a Chancellor.

Merkel is supposed to visit Moscow before that and discuss some terms of future cooperation between the Russia and Europe. The arrest of another Russian spy gives her visit a negative context.

The fact that he is British shows that Britain is keen to prevent any kind of continental alliances against The Island.
