George Osborne, his former Labour rival Ed Balls and BBC Trust chairman Rona Cameron are to attend the secretive Bilderberg Group conference, it emerged today.
Politicians, bankers, spies, business leaders and royalty will rub shoulders at the conference, later this week, held this year at Telfs-Buchen in Austria.
The talks are shrouded in mystery because no record is kept of who politicians meet or what is discussed.
Since its inception in 1954, Bilderberg has held annual gatherings of 120-150 invited political leaders and business experts.
Those on the guest list this week include the heads of banking and financial giants including Deutsche Bank, Santander, AXA Group, JP Morgan, HSBC, BlackRock and Goldman Sachs.
Senior figures from Royal Dutch Shell, BP, AXA Group, Google, Airbus, Fiat Chrysler, LinkedIn, Siemens and Ryanair are also expected.
