Sweden has expelled two Russian diplomats for alleged corporate espionage. The two are suspected of involvement in a spy ring at Ericsson, the technology and defense company that makes radar and missile-guidance systems for Swedens Gripen fighter jet. Five Ericsson staff are under investigation for passing secrets to Russia, although none have yet been charged with a crime. The Stockholm daily Dagens Nyheter suggested that the Russian spying could be in retaliation for Swedens purchase of top-secret information on Russian radar. Russia is expected to respond in the usual diplomatic fashion, by expelling two Swedish diplomats from Moscow.
