Kirill Shamalov purchased large stake in Russian petrochemicals company months after marrying Katerina Tikhonova

A Russian businessman who was married to Vladimir Putin's daughter received an estimated $380m (283m) stake in a Russian petrochemicals company for just $100, an investigation by Russia's iStories investigative outlet has claimed.

The investigation, published in collaboration with the the Organised Crime and Corruption Reporting Project (OCCRP), used a trove of leaked emails to shine new light on the closed circle of family and associates who surround the Russian president.
