It will feature Swiss Finance Minister Ueli Maurer, French Economy Minister Bruno Le Maire, the head of Germany's Christian Democrats, Annegret Kramp-Karrenbauer, and Crédit-Suisse CEO Tidjane Thiam among others.

According to Swiss daily Tages Anzeiger, US Secretary of State Mike Pompeo will also be among the attendees, although he is not on the official guest list on the Bildberg website.

The Swiss paper reports that Pompeo is set to sit down with Ueli Maurer. The two are tipped to discuss the situation in Iran where Switzerland represents US interests.

However, the Swiss Finance Ministry told The Local on Tuesday that no meeting was envisaged between Pompeo and Maurer.

The yearly Bilderberg talk-fest, which dates back to 1954, features a guest list of around 130 people from Europe and North America including everyone from royals to business tycoons and academics.
