This weekend 150 of the world's most powerful people are meeting in the Kempinski Hotel Taschenbergpalais in Dresden, Germany.

A £25million security operation means their secret meetings will be protected by hundreds of police officers and soldiers.

But who are they and what are they doing?

It is known as the Bilderberg Conference and many people believe those attending are part of a 'new world order' who secretly run the world.

Some even claim it is a cover name for the illuminati, a secret and sinister order founded in 18th century Bavaria.

Ever since its formation in 1954 – at the Hotel Bilderberg in the Netherlands – the talks have been shrouded in mystery because no minutes are kept of what was discussed.

Journalist Jon Ronson wrote a book about the Bilderberg Group, called Them, and the late Labour MP Denis Healey, who co-founded the group, told him: 'Bilderberg is the most useful international group I ever attended. The confidentiality enabled people to speak honestly without fear of repercussions.'
