Diamond Ocean Enterprises, a Mossack Fonseca entity set up in 2005, reported its purpose as financial consulting to a Namibian diamond manufacturer and polisher. According to the law firm's records, Deutsche Investment Consultants (Asia) Limited, a Mossack Fonseca company set up in the British Virgin Islands for the now-imprisoned Mafioso Vito Palazzolo by Wolf-Peter Berthold, a German banker based in Hong Kong, is a director of the firm. Its shareholders include Peter von Palace Kolbatschenko, Palazzolo's son, Berthold, and Giovanni Agusta.
Initial reports identified five then-heads of state or government leaders from Argentina, Iceland, Saudi Arabia, Ukraine, and the United Arab Emirates as well as government officials, close relatives, and close associates of various heads of government of more than forty other countries. Names of then-current national leaders in the documents include President Khalifa bin Zayed Al Nahyan of the United Arab Emirates, Petro Poroshenko of Ukraine, King Salman of Saudi Arabia, and the Prime Minister of Iceland, Sigmundur Davíð Gunnlaugsson.
Initially, mainstream Russian media almost entirely ignored the leak. Neither state-owned Channel 1 and Rossiya 1, nor privately owned REN-TV and NTV, mentioned the story on April 4, the day the story broke. The minimal coverage of the story ran in the middle of the night on Vesti TV and was in relation to Lionel Messi and Michel Platini. An exception was the Russian opposition newspaper Novaya Gazeta, described as "the ICIJ's Russian partner", which reported on the story both in hard copy and online.
President Barack Obama addressed the overseas shell companies listed by the leak in a press conference: "It's not that they're breaking the laws," he said, "it's that the laws are so poorly designed that they allow people, if they've got enough lawyers and enough accountants, to wiggle out of responsibilities that ordinary citizens are having to abide by." Although no leader in the US was mentioned in the Panama Papers, Obama said that "Frankly, folks in America are taking advantage of the same stuff".
