The news Germany's foreign minister met the British ambassador over reports of spying from the British embassy in Berlin has been taken a lot more seriously in the German capital than some people in Britain might imagine.
Reports claim top-secret listening posts were operating in the centre of the city and the Germans really don't know how much or how many conversations 'spies' were able to listen into.
This latest tapping of communications speculation comes just a fortnight after Chancellor Angela Merkel's own phone was tapped into by the Americans.
The Germans would have suspected the UK Government Communications Headquarters (GCHQ) may have been involved in this.
However, reports a European ally, a member of the European Union, Britain, was spying for the Americans effectively right in the heart of the Germany has provoked a furious response from some politicians who want to impose financial sanctions.
By and large the general response is a bit more moderate but it couldn't have come at a worse time for Prime Minister David Cameron.
