If UK media adopted NYT’s new rules for anonymous sourcing, how would political coverage be affected?

The New York Times is changing its policy on anonymous sources to require two out of three top editors to review and sign off on articles that primarily depend on anonymous sources. But if media in the U.K. were to adopt a similar policy, The Guardian’s Roy Greenslade questions how many political stories could be published. Single anonymous sources are key to many of the U.K.’s political stories, simply because the stories wouldn’t be reported otherwise, Greenslade writes: “We know it’s wrong, but how else can we inform the public? … Few, if any [sources], want to go on the record and there are always problems of motivation and spin.”
