Rinat Akhmetov

Oligarch, sponsor of the Party of Regions, controls group of MPs in Parliament

Ukraine's wealthiest and son of a coal miner, Rinat Akhmetov has been dealing with uprisings at his coal mines with miners at one mine seizing offices in protest against their dismissal. But the value of his energy company, DTEK, continues to increase with rising demand. Strength in the energy sector has offset declines in his steel producer Metinvest which is suffering from depressed steel prices. Akhmetov has reportedly fallen out with Ukraine's President Viktor Yanukovych, with whom he had a strong alliance over the past decade; Akhmetov also stepped down from Parliament.
