Bilderberg: Protesters and conspiracy theory in Watford 10 June 2013 Last updated at 11:38 Help Bilderberg is the name for a group of transatlantic VIPs who meet every year, at posh locations, but usually do not say who is coming, what they are talking about, and the press and public are kept away. Guests include Henry Kissinger, the head of the IMF and and David Cameron, who joined them for this year's event near Watford, where a list of guests was released this time. Adam Fleming met some of those protesting outside the Hertfordshire venue.
