Czech downstream oil group Unipetrol said it was prepared to raise its stake in Ceska Rafinerska if one the refinery's two other shareholders were to exit, it said in its 2010 annual report.

It said it would do so if the economic terms were justified.

Unipetrol had said earlier this month that it was informed that Italy's Eni is in talks with Russia's Gazprom  to sell its nearly 33% stake in Ceska Rafinerska.
