Once the apex of conspiracy theories, the influential group signals a shift by naming ex-Nato chief as new co-chair

The former head of Nato, Jens Stoltenberg, has been named the new co-chair of the influential Bilderberg Group, which convenes a yearly transatlantic policy conference and has long been the subject of conspiracy theories around the extent of its power to shape global events.

After a turbulent decade at the helm of the alliance’s military, Stoltenberg now takes over at its pre-eminent discussion forum: a fiercely private four-day event frequented by prime minsters, EU commissioners, bank bosses, corporate CEOs and intelligence chiefs.
