Numerous Web sites have published a list of delegates attending the Bilderberg 2010 conference in Spain between June 3 and June 6.  It's an annual invitation-only meeting of some of the world's most influential leaders in government, banking, business, and the media.

The Bilderberg conference has attracted the interest of conspiracy theorists, in part because of its secrecy.  The list includes the usual heavyweights, such as Bill Gates, Google CEO Eric Schmidt, Richard Holbrooke (President Barack Obama's special representative to Afghanistan and Pakistan), Henry Kissinger, former U.S. Federal Reserve chief Paul Volcker, Obama's top economic adviser Lawrence Summers, former U.S. treasury secretary Robert Rubin, and Richard Perle, a U.S. neocon best known as a chief cheerleader of the 2003 attack on Iraq.

The are also a couple of surprising Canadian names on the list: B.C. premier Gordon Campbell and CBC chief correspondent Peter Mansbridge.

"Bilderberg's only activity is its annual Conference," states a news release on the Bilderberg site. "At the meetings, no resolutions are proposed, no votes taken, and no policy statements issued. Since 1954, fifty-seven conferences have been held. The names of the participants are made available to the press. Participants are chosen for their experience, their knowledge, and their standing; all participants attend Bilderberg in a private and not an official capacity."

Development economist Dambisa Moyo, who is a fierce critic of international aid for Africa, is also among the attendees, along with numerous corporate chiefs.
