spying on Berlin, German Foreign Minister Frank-Walter Steinmeier said yesterday.
Officials said the U.S. spy chief would be leaving the country soon.
"Our decision to ask the current representative of the U.S. intelligence services to leave Germany is the right decision, a necessary step and a fitting reaction to the break of trust which has occurred," Steinmeier told reporters.
"Taking action was unavoidable, in my opinion. We need and expect a relationship based on trust."
He said a strong transatlantic partnership was especially important now given international crises. He would tell U.S. Secretary of State John Kerry when they meet in Vienna at the weekend for talks on Iran's nuclear programme that Germany was eager to revive that partnership on the basis of mutual trust.
The scandal has chilled relations with Washington to levels not seen since Chancellor Angela Merkel's predecessor opposed the U.S. invasion of Iraq in 2003. It follows allegations that Merkel herself was among thousands of Germans whose mobile phones have been bugged by American agents.
Merkel has not had a phone conversation with U.S. President Barack Obama since Berlin asked the CIA station chief to leave, but the two are in close contact, a German government spokesman said on Friday.
"There has been no phone call (between) the Chancellor and Washington and none is planned. But you know the Chancellor and the American President are in good contact with each other," Merkel's spokesman Steffen Seibert told a news conference.
Seibert said the government expected the U.S. intelligence representative to leave Germany "promptly". The U.S. official has not been publicly named.
The decision to order the CIA representative out came after dramatic reports of U.S. espionage activity in Germany.
