From FT "India’s billionaire Ruia family are putting the final touches to an improved offer for Essar Energy as they push ahead with plans to take the company back into private ownership.

The Ruias, whose initial buyout bid of 70p per share was rejected by minority shareholders last week for undervaluing the company, are working with advisers including Barclays, Russia’s VTB Bank and Clifford Chance, the law firm, on a higher offer, according to sources familiar with the plans."
