Data leak reveals financial dealings

German newspaper Sueddeutsche Zeitung says it has obtained a vast trove of documents detailing the offshore financial dealings of the rich and famous.

The Munich-based newspaper says it received the data, known as the Panama Papers, from an anonymous source more than a year ago and shared it with more than 100 news outlets.

Their work was co-ordinated by the International Consortium of Investigative Journalism, a non-profit organisation in Washington.
