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, has the potential to cause a seismic shock worldwide to the booming offshore trade. The naming project may be extremely damaging for confidence among the world's wealthiest people, no longer certain that the size of their fortunes remains hidden from governments and from their neighbours. As well as Britons hiding wealth offshore, an extraordinary array of government officials and rich families across the world are identified, from Canada, the US, India, Pakistan, Indonesia, Iran, China, Thailand and former communist states. The Caribbean micro-state has incorporated more than a million such offshore entities since it began marketing itself worldwide in the 1980s. Owners' true identities are never revealed. Even the island's official financial regulators normally have no idea who is behind them. The British Foreign Office depends on the BVI's company licensing revenue to subsidise this residual outpost of empire, while lawyers and accountants in the City of London benefit from a lucrative trade as intermediaries.
