A huge leak of 13.4 million documents from an offshore law firm and a trust company in Singapore is drawing comparisons to last year's Panama Papers scandal.

The documents, dubbed the Paradise Papers, were obtained by the German newspaper Sueddeutsche Zeitung and shared with the International Consortium of Investigative Journalists (ICIJ).

The papers "show how deeply the offshore financial system is entangled with the overlapping worlds of political players, private wealth and corporate giants," the ICIJ wrote on Sunday.

The names of more than 120 politicians in nearly 50 countries appear in the 1.4 terabyte data leak, along with figures from the worlds of sports and business.
