Former Yukos CEO Mikhail Khodorkovsky has said that the question of involvement in politics is closed to him.

"There is no question of politics, if politics is understood as struggle for power, for me either. I am not interested or willing to take the way politicians in Russia have to a stance that is not quite frank. I believe that I have won for myself one right which is worth much - the right not to say what I don't think," he said to journalists on Sunday.

Khodorkovsky added that he does not intend to engage in business. "The question of business is closed to me, including from the point of view of fighting for my previous assets. I will not take part in it for the simple reason that I don't want to waste my time on that," he added.
