Now that Deep Throat, the most most famous confidential source in journalism, has been outed, Kevin Drum has a new object for speculation: Who leaked the Downing Street Memo Minutes to the Sunday Times? Unlike here in the UK, the Times’ story on the 2002 meeting in Downing Street about Iraq is now a hot story in the US blogosphere.

Drum points to a story suggesting it could be Sir Christopher Meyer, the former UK ambassador to the United States.

The problem with this speculation is that the Sunday Times may not know the answer themselves. There is probably no smoke-filled scene in an underground carpark for the movie version of this story. For all we know, a brown envelope just happened to end up at the Sunday Times’ front desk.

Update: Freiheit und Wissen doesn’t want to know.
