The past 24 hours have seen a flurry of anger, denials and promises to investigate after the Pandora Papers made global headlines, where almost 12 million documents were leaked, revealing hidden wealth, tax avoidance and, in some cases, money laundering by some of the world's rich and powerful.
The data was obtained by the International Consortium of Investigative Journalists in Washington DC, which has been working with more than 140 media organisations on its biggest ever global investigation.
Will Fitzgibbon is one of the lead reporters on this project, he spoke to Corin Dann.
