This week, around 130 of the world's most rich and powerful figures will gather at the top-secret Bilderberg conference in Dresden, Germany.
The four-day event runs from Thursday until Sunday, and is an annual opportunity for those from the banking, academic, political and business worlds to mingle confidentially.
No agendas, resolutions, votes or policy statements are made as a result of the conference, but some criticise it as an opportunity for a global elite to come together and decide on actions that affect the lives of billions of people.
Prominent figures, such as Ryanair's Michael O'Leary, ex-CIA chief David Petraeus and the Dutch King are among those on the guestlist.
But ten Brits have also been invited. Here's who they are and why Bilderberg is so interested in having their ears:
Marcus Agius is chair of the British Banker Association, a trade group which lobbies on behalf of its members.
Among those banks it represents are HSBC, JP Morgan, Lloyds and the Bank of India.
In 2012, the association was stripped of its role as the rate setter for Libor, one of the fundamental standards for global financial markets.
Agius is also a former group chair of Barclays and sits as a non-executive board director on the BBC Executive Board.
A former BP non-executive director, Scottish-born Douglas Flint is a specialist in multinational financial reporting and treasury operations.
He is now group chair of HSBC, a position he earned after a boardroom battle back in 2010 and is a regular at Bilderberg.
Flint is thought to have attended five of the last six top secret conferences.
From the House of Commons, Labour MP Helen Goodman is also on the confirmed guest-list for this year's event.
She has served in numerous briefs in government, including the Treasury and Department for Work and Pensions.
2016 will be the Labour MP's first time at Bilderberg.
She memorably came under fire last year for tweeting a “bizarre” criticism of health secretary Jeremy Hunt’s wife
The MP for Bishop Auckland wrote: “If China is so great, why did @Jeremy_Hunt ‘s wife come to England?”

Guy Standing is a University of London professor, and founder of the Basic Income Earth Network, an NGO promoting basic income as a right.
He has held a number of senior academic positions, including at at the universities of Bath and Monash (in Melbourne, Australia).
Professor Standing has previously declared universal basic income a "21st century economic right" and wrote in a book published in 2011 that globalisation was to blame for pushing more workers into a new social class - the precariat.

Previous attendees at the secret conference include David Cameron, George Osborne and ex-shadow chancellor Ed Balls.
The conference is usually picketed by protestors, often dubbed conspiracy theorists, who believe it is largely a lobbying event that yields no transparency over what discussions take place and how politicians' decisions will affect policy in countries across the globe.
Officially, the Bilderberg group bills itself as designed to "foster dialogue between Europe and North America".
The group's 2013 conference was held in Watford, North London.
