Leading conspiracy theorist Alex Jones has been branded the "worst person I have ever interviewed" by BBC presenter Andrew Neil for shouting throughout a TV interview.
Jones appeared on Neil's Sunday Politics show to rant about a web of conspiracies involving the Bilderberg Group, a nexus of business and political leaders from Europe and North America.
It was another memorable brush with British journalists for Jones, who recently made headlines for trying to get Piers Morgan deported from the United States for speaking out about gun violence.
The American, who claims 3 million people a day visit his website Infowars to listen to his radio show, appeared on screen as the Bilderberg group met at a hotel in Watford, Hertfordshire.
He insisted the Euro currency is a Berlin-inspired master plan by Nazis to conquer Europe and claimed Labour shadow chancellor Ed Balls was among a shadowy group of "puppeteers" controlling the planet, who had threatened to chop his head off.
On Bilderberg, Jones said: "It's the ultimate lobbying meeting, we have forced them from cover.
"The Euro is a Nazi German plan to take over Europe... BB [Bilderberg] is heavily involved in the EU plan and helped hatch it and it's a Nazi plan."
Neil told the tin foil hat society's loudest campaigner to "shut up" two times, prompting a furious outburst from Jones, who claimed the BBC was a part of the conspiracy to control the world.
Waggling his finger at Neil, Jones ranted: "You keep telling me to shut up, this isn't a game. You will not stop freedom. Humanity is waking up. We're in a police state. It's 1984 and you're trying to normalise it."
Neil brought the curtain down on the interview by telling Jones: "You are worst person I have ever interviewed."
Later, he claimed Jones' high-octane performance was "an act."
Government minister withot portfolio Kenneth Clarke chairs a steering group for the Bilderberg group - which is probably rich pickings for fevered minds like Alex Jones.'
Commenting on why the Bilderberg group had such a shadowy reputation, Clarke said press conferences used to be held after each conference - but no reporters turned up.
He said: "It's an informal discussion about politics and the worlds problems with a lot of politicians and businessmen and we always produce lists of whose there. It's not secret but we don't have a mass audience listening to our discussion."
