Bankers, Prime Ministers, CEOs and defence experts will meet in Montreux, Switzerland, to discuss a wide range of topics including Russia, cyber threats and Brexit.
From Thursday to Sunday 130 influential men and women from 23 countries will meet under strict secrecy rules and the precise location of their venue has not been revealed.
Notable attendees include former US Secretary of State Kissinger, Governor of the Bank of England Carney, former CIA director David Petraeus and White House Adviser Jared Kushner, Donald Trump's son-in-law.
