A new investigation by the International Consortium of Investigative Journalists (ICIJ) and more than 100 other news organisations around the globe reveals the offshore links of some of the planet’s most prominent people, including over 500 from India.

According to report in The Indian Express, which was part of a coalition of media outlets investigating the documents, says its eight—  month investigation of over 36,000 files has revealed around 500 Indian names, including actor Amitabh Bachchan and Aishwarya Rai Bachchan, real—  estate developer DLF’s KP Singh, to politician Anurag Kejriwal, on the firm’s list of offshore companies, foundations and trusts.

The revelation of the “Panama Papers” detailing the off—  shore structures of many wealthy
clients is a “crime” and an “attack” on Panama, the law firm at the heart of the scandal has said.

“This is a crime, a felony,” Ramon Fonseca, one of the founders of the Panamanian firm Mossack Fonseca, said yesterday.

“This is an attack on Panama because certain countries don’t like it that we are so competitive in attracting companies,” he told AFP.
