The Bilderberg Group has long been the subject of speculation. But what do we really know about the secretive international meetings between top politicians and bosses?
The location of the meetings is now public. Last year, the Danish capital of Cophenhagen was the venue of choice.
This year, the world’s elites will travel to the Interalpen-Hotel Tyrol in the Austrian Alps.
The group releases a list of attendees. From the UK this year George Osborne and Ed Balls are attending.
Other people going to the 2015 meet-up include José Barroso, the former EU Commission President, and executives from firms including Google, BP, Shell, and Deutsche Bank.
