Ordinary citizens can only guess at the goings-on at the annual meeting of the secretive Bilderberg Group, a media-barred pow-wow of the global elite that in the past has reportedly attracted former US President Bill Clinton, Tony Blair and David Cameron, and US treasury secretary Timothy Geithner. The heavyweight weekend retreat kicked off yesterday with hordes of police security and a gag order for employees at the luxury Dolce. None of the illustrious guests posed for photos or spouted prepared statements for the media. Instead, activists, journalists and bloggers attempted to stake out positions in the surrounding hills to catch glimpses of this year's participants, guerrilla-warrior style. The cloak-and-dagger theorists scored a point this week when ... Daniel Estulin addressed the European Parliament on the invitation of an Italian member, Mario Borghezio. Mr Estulin, an investigative journalist who has written two best-selling books on the subject, contends that the Bilderberg Club" is not a classic conspiracy but a potentially dangerous meeting of minds with a common goal: to centralise global economic power to benefit corporations. He defined it as "a virtual spider web of interlocking financial, political and industrial interests". "It isn't a secret society," he said. "No matter how powerful they are, no group sits around a table holding hands and deciding the world's future. It is an ideology."
