Some of the data released Sunday by Germany’s newspaper Sueddeutsche Zeitung allegedly showed that Ulyukayev’s son was director of a shell company called Ronnieville that was set up in the British Virgin Islands in 2004. It existed until 2009.
"I do not completely understand the mechanism and character of the ongoing media hype. I have no relations to these events. I have been filing my taxes and they can be easily traced back for years," Ulyukayev told reporters.
Mossack Fonseca responded by refusing to validate the information contained in the leaks and accused reporters of gaining unauthorized access to its proprietary documents. It warned that using unlawfully-obtained data was a crime that it would not hesitate to punish by legal means.
