The Pentagon's principal spy agency is appointing a British air force officer as its first deputy director in charge of improving "integration" between U.S. intelligence units and spy agencies of other English-speaking countries.

U.S. intelligence agencies have long had close relationships with their British counterparts, but former and current U.S. intelligence officials said this is the first time they knew of a U.S. spy agency naming a foreigner to a top executive position.

In an official announcement, the Pentagon said that the Defense Intelligence Agency (DIA) has chosen Air Vice Marshal Sean Corbett of Britain's Royal Air Force as its first "deputy director for commonwealth integration."
