Roman Abramovich made his fortune in the 1990s in Russia, at a time when businesses such as oil, gas and commodity trading might only be done with strong political connections. He himself admits it.

Abramovich was then deputy, then governor. In 2005, he sold his biggest company, Sibneft, to the state.
