Khodorkovsky quits Yukos shares Jailed tycoon Mikhail Khodorkovsky has transferred his controlling stake in oil giant Yukos to a business partner. Mr Khodorkovsky handed over his entire 59.5% stake in holding company Group Menatep - which controls Yukos - to Leonid Nevzlin. A close ally of the ex-Yukos boss, Mr Nevzlin is currently based in Israel. Mr Khodorkovsky handed over his stake after the forced sale of Yukos' core oil production unit, Yuganskneftegaz to pay a giant tax bill. Yuganskneftegaz was sold off at auction in December last year, eventually falling into the hands of state oil firm Rosneft in a deal worth $9.4bn (£5bn). "Since the sale of Yuganskneftegaz, I have been delivered of (all) responsibility for the business that remains and the group's money as a whole," Mr Khodorkovsky said. "It is all over. As before, I see my future in public activity to build a civil society in Russia." Mr Nevzlin is Yukos' largest shareholder but is living in self-imposed exile in Israel. Yuganskneftegaz pumps around 1 million barrels of oil a day. It was sold by the Russian authorities to recover government tax claims against Yukos totalling over $27bn. Previously considered to be Russia's richest man, with an estimated fortune of $15bn, Mr Khodorkovsky is currently on trial for fraud and tax evasion following his arrest in October 2003. However, the charges are widely seen as politically motivated and part of a drive by Russian President Vladimir Putin to rein in the country's super-rich business leaders, the so-called oligarchs. It is also believed that Mr Khodorkovsky was particularly targeted because he had started to bankroll political opponents of Mr Putin.
