New Panama Papers revealed: leak exposes financial affairs relatives of President Xi and politburo members, Jackie Chan, Putin aides, world leaders

A massive leak of 11.5 million tax documents on Sunday exposed the alleged secret offshore financial dealings of relatives of Chinese President Xi Jinping and other senior Chinese figures, aides to Russian president Vladimir Putin, other world leaders and celebrities including Jackie Chan and Barcelona footballer Lionel Messi.

An investigation into the documents by more than 100 media groups, described as one of the largest such probes in history, revealed the hidden offshore dealings in the assets of around 140 political figures - including 12 current or former heads of states.

The vast stash of records was obtained from an anonymous source by German daily Sueddeutsche Zeitung and shared with media worldwide by the International Consortium of Investigative Journalists (ICIJ).

The investigation yielded 11.5 million documents from around 214,000 offshore entities, the ICIJ said. The leaked documents came from Mossack Fonseca, a Panama-based law firm with offices in more than 35 countries.

Though most of the alleged dealings are said by the ICIJ to be legal they are likely to have a serious political impact on many of those named.
