Millions of internal records have leaked from Britain's offshore financial industry, exposing for the first time the identities of thousands of holders of anonymous wealth from around the world, from presidents to plutocrats, the daughter of a notorious dictator and a British millionaire accused of concealing assets from his ex-wife.
The leak of 2m emails and other documents, mainly from the offshore haven of the British Virgin Islands (BVI), has the potential to cause a seismic shock worldwide to the booming offshore trade, with a former chief economist at McKinsey estimating that wealthy individuals may have as much as $32tn (£21tn) stashed in overseas havens.
In France, Jean-Jacques Augier, President François Hollande's campaign co-treasurer and close friend, has been forced to publicly identify his Chinese business partner. It emerges as Hollande is mired in financial scandal because his former budget minister concealed a Swiss bank account for 20 years and repeatedly lied about it.
In Mongolia, the country's former finance minister and deputy speaker of its parliament says he may have to resign from politics as a result of this investigation.
But the two can now be named for the first time because of their use of companies in offshore havens, particularly in the British Virgin Islands, where owners' identities normally remain secret.
The names have been unearthed in a novel project by the Washington-based International Consortium of Investigative Journalists [ICIJ], in collaboration with the Guardian and other international media, who are jointly publishing their research results this week.
