PARIS - Close aides of Russian president Vladimir Putin, the king of Saudi Arabia and the prime ministers of Iceland and Pakistan are among those whose assets feature in a vast expose of tax havens published Sunday after a year-long investigation into 11.5 million leaked documents.

The assets of around 140 political figures - including 12 current and former heads of states - are mentioned in the revelations, according to the probe by International Consortium of Investigative Journalists (ICIJ) and German daily Sueddeutsche Zeitung. The investigation yielded 11.5 million documents from around 214,000 offshore entities, the ICIJ said on its website. The leaked data from 1975 to the end of last year provides what the ICIJ described as a “never-before-seen view inside the offshore world.” Names figuring in the leak included the president of Ukraine, the Saudi king and the prime ministers of Iceland and Pakistan, the ICIJ statement said.

The leaked documents came from Mossack Fonseca, a law firm with offices in more than 35 countries. They were reviewed by a team of more than 370 reporters from over 70 countries.

Monitoring Desk adds: According to Indian Express, the sons and daughter of PM Nawaz Sharif set up at least four offshore companies in British Virgin Islands, ICIJ report said. These companies owned at least six properties overlooking London’s Hyde Park. The report said Nawaz’s children “did not respond to repeated requests for comments”. According to a private TV channel, the prime minister has rejected the report.
