Chelsea owner Abramovich, who will be delighted with the team's form in the Premier League, has planning permission to build a 60,000-seat stadium costing £500m. Abramovich, 50, was born in Saratov, just south of the Arctic Circle, and he and the late Boris Berezovsky bought the Sibneft oil operation in 1995 for £120m.
Berezovsky went into exile and sold his shares to Abramovich, who sold Sibneft to Gazprom, the Russian natural gas monopoly. The stake held by Abramovich and his partners was worth £7.5bn. He has holdings in 13 businesses worth a combined £4bn, five homes and a vast art collection. His divorce from ex-wife Irina Malandina (qv) was costly. He is now married to Dasha Zhukova, 35.
