Amid another leak of documents revealing large-scale international tax avoidance, the secretary-general of the Organisation for Economic Co-operation and Development (OECD) said Monday that tax avoidance was fast becoming a thing of the past. “When we’re talking about the ‘Panama Papers’ or ‘Paradise Papers’we’re talking about a legacy that is fast disappearing,” Angel Gurria said. Speaking at the Confederation of British Industry (CBI) conference in London, Gurria said governments were working hard to stop tax avoidance and evasion.
