TCS Group co-managers Oliver Hughes and Pavel Fedorov left the company. "Shareholding rights from TCS Group have been transferred to a team of Russian managers, for this reason the status and positions of the Cypriot structure's employees have lost their relevance," the group said. Founder Oleg Tinkov is again negotiating the sale of a 35% stake in TCS Group held in the family trust, an acquaintance of Oleg Tinkov and two people with knowledge of the sale proposal told RBC magazine.
