As reported by Censor.NET citing Ukrainska Pravda, according to the investigation materials, the information comes from numerous documents of Panama company Mossack Fonseca & Co, which have been received from the office of this company on British Virgin Islands, one of the largest offshore centers of the world. Mossack Fonseca & Co provides legal and trust services, including registration of offshore companies.
These documents were also received by German newspaper Süddeutsche Zeitung, which provided them to its colleagues in the ICIJ - International Consortium of Investigative Journalists, and OCCRP - Organized Crime and Corruption Reporting Project.
OCCRP posted, among other, materials about three Ukrainians - President Petro Poroshenko, former Prime Minister Pavlo Lazarenko, and Kyiv Post newspaper owner Mohammad Zahoor - a British businessman living and having business in Ukraine.
Part of the investigation about Poroshenko's tax evading efforts can be read here.
Materials about Zahoor read that he is one of two dozens of people related to Ukraine, whose names are featured in the vast mass of documents from the office of the company Mossack Fonseca & Co. No information about other Ukrainians, apart from the mentioned three, has been published yet.
The article about Zahur describes events of the 1990s related to gas corruption. The same case features former PM Pavlo Lazarenko and future PM Yuliia Tymoshenko, as well as "Yedyni Enerhetychni Systemy Ukrainy" company.
The article reads that during the investigation, the prosecution gathered almost 11,000 volumes of materials, including hundreds of financial and banking documents, expert reports, auditing and tax check-up reports. However, over the past years, depending on political situation in Ukraine, the case was either closed or opened again. The last time it was closed on Feb. 28, 2014.
The investigation also features a lot of materials about offshore deals of Russian President Vladimir Putin, his press secretary Dmitry Peskov, well-known football player Lionel Messi, former Georgian PM Bidzina Ivanishvili, and others.
Special attention is paid to Russian violin player and close friend of Putin Sergey Roldugin. According to the investigation, he is a nominee owner of the multi-billion empire of Putin and his cronies.
