Get yer tinfoil hat ready.

For those of you not prone to tinfoil hat bouts of paranoia, skip this post.

But on this creepy grey morning with rolling thunder and no rain, this set off the rightwing paranoid element inside me. A BBC interview, albeit softball, with the head of Bilderberg. Why would he do this? They never talk publicly, even to acknowledge the meetings existence.

In his office, on a private floor above the Brussels office of the Suez conglomerate lined with political cartoons of himself, he told me what he thought of allegations that Bilderberg is a global conspiracy secretly ruling the world.

"It is unavoidable and it doesn't matter," he says. "There will always be people who believe in conspiracies but things happen in a much more incoherent fashion." .....

"I don't think (we are) a global ruling class because I don't think a global ruling class exists. I simply think it's people who have influence interested to speak to other people who have influence," Viscount Davignon says. .....

Will Hutton, an economic analyst and former newspaper editor who attended a Bilderberg meeting in 1997, says people take part in these networks in order to influence the way the world works, to create what he calls "the international common sense" about policy.

"On every issue that might influence your business you will hear at first-hand the people who are actually making those decisions and you will play a part in helping them to make those decisions and formulating the common sense," he says.

And that "common sense" is one which supports the interests of Bilderberg's main participants - in particular free trade. Viscount Davignon says that at the annual meetings, "automatically around the table you have internationalists" - people who support the work of the World Trade Organisation, trans-Atlantic co-operation and European integration.

Bilderberg meetings often feature future political leaders shortly before they become household names. Bill Clinton went in 1991 while still governor of Arkansas, Tony Blair was there two years later while still an opposition MP. All the recent presidents of the European Commission attended Bilderberg meetings before they were appointed. ....

'Secret Government'

This has led to accusations that the group pushes its favoured politicians into high office. But Viscount Davignon says his steering committee are simply excellent talent spotters. The steering committee "does its best assessment of who are the bright new boys or girls in the beginning phase of their career who would like to get known."

"It's not a total accident, but it's not a forecast and if they go places it's not because of Bilderberg, it's because of themselves," Viscount Davignon says.

But its critics say Bilderberg's selection process gives an extra boost to aspiring politicians whose views are friendly to big business. None of this, however, is easy to prove - or disprove.

Observers like Will Hutton argue that such private networks have both good and bad sides. They are unaccountable to voters but, at the same time, they do keep the international system functioning. And there are limits to their power - a point which Bilderberg chairman was keen to stress, "When people say this is a secret government of the world I say that if we were a secret government of the world we should be bloody ashamed of ourselves."

Informal and private networks like Bilderberg have helped to oil the wheels of global politics and globalisation for the past half a century. In the eyes of critics they have undermined democracy, but their supporters believe they are crucial to modern democracy's success. And so long as business and politics remain mutually dependent, they will continue to thrive.

OKAY, I'll put the tinfoil hat away. Sorry, but this interview/article in the mainstream is quite unprecedented, and sometimes the hat comes out on it's own.

Back to normal now.
