Scottish veteran broadcaster Andrew Neil has become the latest recipient of the tornado treatment of American "shock jock" Alex Jones.

BBC's Sunday Politics is normally a sedate affair, a corner of the Sabbath visited only by political anoraks and working journalists. but yesterday a whirlwind took hold.

Mr Neil, who hosts the television programme, began a discussion about the Bilderberg summit, a secretive four-day meeting of some of the world's top powerbrokers, which took place in Watford, then watched the twister unfold.

At first, Mr Jones – who had a high-profile clash with CNN host Piers Morgan in January – began with a gale force eight response, suggesting the Bilderberg Group was responsible for the euro currency, which, according to him, was a "German Nazi plan to take over countries economically".

Eyebrows were raised. Then the wind got up. Mr Jones's voice rose a few decibels as he gesticulated, pointing his finger like a handgun and firing off bullets of indignation.

"I'm trying to warn people and you keep telling me to shut up. This isn't a game, okay?"

Eventually, Mr Neil had seen enough, described his guest as an idiot and declared: "You're the worst person I've ever interviewed."

As the programme music played out, you could hear the American tornado in the background.

Afterwards, Mr Neil, tweeted: "The moment Alex Jones knew he was no longer on air he stopped."
