State-owned Russian energy company Rosneft has won sufficient orders to price its controversial flotation near the top of its range and will close the deal tonight, one day ahead of schedule. The company will be valued at $80bn (€62.8bn).

Bankers leading the deal told investors this morning that Rosneft stock will be offered at $7.50 to $7.85, the top half of the price range, raising $11.6bn for the firm and the Russian government.
