Earlier this month PKN announced it was buying regional newspaper publisher Polska Press, bringing more local media back into Polish hands.

Onet - a Web portal owned by Ringier Axel Springer Media AG - then reported that the refiner could also be interested in taking over Gremi Media, the owner of two nationwide dailies, Rzeczpospolita and Parkiet.

"PKN Orlen has no plans to take over other media," state news agency PAP quoted PKN Orlen's press office as saying.

Separately, Gremi Media said in an emailed statement that it is not a party or subject to any proposals regarding changes in its ownership structure.

Also on Monday, the chief executive of KCI, the company that owns Gremi Media, said in an interview published by Rzeczpospolita daily that while it is looking to sell up to 60% of its shares to smaller investors, it remains a strategic investor in Gremi Media.
