Two Russia's biggest companies, Gazprom and Rosneft have grappled over the status of the country's biggest taxpayer.

      Gazprom has claimed it paid 1.9 trillion roubles in taxes in 2012, while Rosneft only 1.7 trillion, Gazprom's CEO told the Annual General Meeting of shareholders.

      There is no official confirmation since The Federal Tax Service decline to comment, but analysts say the title belongs to Rosneft, as it claims in its advertising. Gazprom's tally includes taxes paid by its subsidiaries such as Gazpromneft and other payments such as the payroll tax, they say
