From the Watford Observer:
A police security cordon around The Grove hotel has now come into effect ahead of the Bilderberg Group meeting.
The security measures, which have been brought in under anti-terror legislation, mean the hotel and its grounds are closed to all non-residential guests until 2pm on Sunday, June 9.
All public rights of way across the grounds of The Grove, including the towpath of the Grand Union Canal, are now suspended for the duration of the conference.
All canal boat moorings in the vicinity of the hotel are also suspended.
Anti-terrorism legislation and a no-fly zone will be used to secure the Bilderberg Group’s meeting at The Grove hotel.
Senior Hertfordshire police officers told Watford residents the measures were being used as a precaution as there was no intelligence about a specific threat.
However at a public meeting this evening officers also said the public had been kept in the dark about the event until recently due to fears it could become a terror target.
Watford Chief Inspector, Nick Caveney, said: “There is no information regarding a terrorism threat.
