No such encounters will take place in Watford this week, as the Bilderberg, the annual conference for 140 of the world’s most powerful, meet for four days at The Grove, a £300-a-night golf hotel close to the M25. The entire hotel has been booked out, and a high fence erected around the exclusion zone. Armed checkpoints have been set up on local roads, and locals must show their passports to enter their own driveways. The Home Office may foot the bill. A US news site dedicated to uncovering conspiracies had booked a room for last week but were told by phone not to turn up.
