KIEV (Sputnik) — On Sunday, the German newspaper Sueddeutsche Zeitung exposed alleged involvement of a number of former and current world leaders, including Ukraine's president, in tax havens schemes using the information obtained in a data leak by the firm.
"We demand Poroshenko, which is on his way to Japan, to turn his plane around and come to the Ukrainian parliament, give an account of corrupt practices and begin the real fight against corruption," Lyashko told 112 Ukraine broadcaster.
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.
