Origins and continuation
Deltour’s LuxLeaks journey started in August 2010. According to Support-Antoine.org, he had gone to copy some training documents while quitting his job at PwC, when he happened upon electronic records of the tax deals. Deltour copied such records as well and held on to them, until investigative journalist Perrin contacted him in summer 2011, and he decided to give the journalist the documents.
Deltour told Media Freedom Conference participants that Perrin had approached him after spotting some comments he had made on the Internet and finding him "well-informed". Deltour remained an anonymous source until Perrin’s "Cash Investigation" broadcast broke the story in 2012, with the company PwC filing a complaint shortly afterwards. He said the legal procedures encouraged him to go public, and that he was even arrested.
When asked if he would do it again, Deltour replied:
Yes, because it led to concrete consequences."
LuxLeaks picked up more steam two years later, when some 40 media organisations linked to the International Consortium of Investigative Journalists (ICIJ) ran articles disclosing information from the fiscal documents. Such leaks exposed players from all over the world and were published internationally, including in the countries where people were found to have participated in the tax scheme. The response was swift and widespread, and countries' authorities promised to take action, besides the EU institutions.
In 2015, the members of the ICIJ would be the ones to break the global Panama Papers scandal. The leak, the largest ever to date, involves more than 11.5 million records exposing a corrupt system of offshore companies implicating powerful politicians from more than 50 countries, their relatives and close friends, and others. The whistleblower in this case has managed to be kept anonymous.
