The German government has ordered the expulsion of a CIA official in Berlin in response to two cases of alleged spying by the US.

The official is said to have acted as a CIA contact at the US embassy, reports say, in a scandal that has infuriated German politicians.

A German intelligence official was arrested last week on suspicion of spying.

An inquiry has also begun into a German defence ministry worker, reports said.

"The representative of the US intelligence services at the embassy of the United States of America has been told to leave Germany," government spokesman Steffen Seibert said.

Germany is an ally, and the US spying on them is totally insane, this is the second time.
