The secret deals and hidden assets of some of the world’s richest and most powerful people have been revealed in the biggest trove of leaked offshore data in history.

Branded the Pandora papers, the cache includes 11.9m files from companies hired by wealthy clients to create offshore structures and trusts in tax havens such as Panama, Dubai, Monaco, Switzerland and the Cayman Islands.

They expose the secret offshore affairs of 35 world leaders, including current and former presidents, prime ministers and heads of state. They also shine a light on the secret finances of more than 300 other public officials such as government ministers, judges, mayors and military generals in more than 90 countries.
