Sonnette Overseas and International Media Overseas were created by Bank of Russia, a privately owned St Petersburg-based bank which the United States sanctioned following the annexation of Crimea because of its close links to Putin's inner circle.
The papers reveal that Roldugin holds a 3.2 per cent stake in the bank, according to the International Consortium of Investigative Journalists, one of the organisations that received the leaked documents.
Other prominent Russian names in the papers include Arkady and Boris Rotenburg, judo-sparring partners of Putin who have amassed fortunes during his 15 years in power and who were also sanctioned by the US as close Putin associates.
The newly published documents show the billionaire brothers control seven companies registered in the British Virgin Islands, which they have used for a number of purposes including investing in pipeline contraction and buying equipment for building an Italian villa for Igor Rotenburg, Arkady's son.
In an apparent reference to the leak last week, Putin's press secretary said Western media and secret services were preparing an "information attack" against the Russian President ahead of parliamentary elections in September. "Here we see no intent to conduct objective investigations, we see just an intention to publish a hatchet job," he said.
Mossack Fonesca did not serve only the Russian elite.
Putin's arch enemy, Ukrainian President Petro Poroshenko, also appears to have made use of the Panamanian law firm.
Poroshenko, a chocolate tycoon who promised to sell most of his assets during his campaign for the presidency, appears to have become sole shareholder of a British Virgin Islands company called Prime Asset Partners Limited in August 2014, as Russian troops swarmed into Eastern Ukraine.
Poroshenko's spokesman said the move was unrelated to political or military developments and said its establishment was part of a move to prepare Roshen, Mr Poroshenko's company, for sale.
Also named is the president of Argentina, Mauricio Macri, who was director and vice president of a Bahamas company managed by Mossack Fonseca when he was a businessman and the mayor of Buenos Aires. A spokesman for Macri said the president never personally owned shares in the firm, part of his family's business.
The children of Nawaz Sharif, the Pakistani Prime Minister, set up four offshore companies, which owned at least six upmarket properties overlooking London's Hyde Park, the law firm's records show. Sharif denies any link to the properties.
