5 big leaks of tax-haven records before the Pandora Papers

The Pandora Papers, a huge cache of data containing secret details of offshore bank accounts and shell companies, is thought to be the largest ever leak of tax-haven financial information. The files, stemming from 14 offshore-services firms, were leaked to the International Consortium of Investigative Journalists, which shared them with its partner media outlets (including CBC/Radio-Canada) and began publishing stories on Oct. 3. 

But the Pandora Papers isn’t the first such leak. Confidential lists of offshore account-holders have found their way into the hands of journalists and governments a number of times over the last decade and a half. Here are five important previous leaks of records from various tax havens:
