Britain's richest man, since he moved here from Russia in 2003.
How did he earn his millions?
The shy 37-year-old made £7.5 billion through oil trading in western Siberia, and Sibneft, Russia's fastest-growing energy business, valued at £8.8 billion. He capitalised on the confusion about free-market principles to build up a stake in former state enterprises, allegedly buying up government-allocated share vouchers and exploiting Yeltsin's 'Loans for Shares' scheme.
What's the secret of his success?
Opportunism: the post-perestroika privatisation of Soviet state assets made Abramovich a billionaire. 'It was just a question of timely investment and share consolidation,' claims his PR.
