KIEV, March 1 – President Viktor Yanukovych says that he doesn't know any details about the growth in the income of his son Oleksandr.

"I know no details. I know that he is used to working a lot, and has created a good team. The main thing I demand of him and constantly tell him, is everything they do, they must do transparently, since he's under the microscope," Yanukovych said during the final press conference in Kiev on Friday answering the media's question of how his son became a billionaire.

The head of the state advised the journalist to put this question directly to Oleksandr Yanukovych.

"You can put this question personally to him. He has slightly more time than I do, and he meets with press more often. Nobody will refuse you, come and he'll answer your questions," the president said.
