Meanwhile, uncertainty remains over claims that Gazprom has successfully purchased 3% of takeover target Sibneft's shares on the open market. According to the Moscow Times and Mosnews, the gas major has bought the shares in a move to discourage potential rival suitor Rosneft. However, other reports have thrown scorn on the contention, pointing to the lack of activity in Sibneft's share price. Gazprom has not commented on the speculation.
