Polsat & News Corp.

Global media groups News Corporation Inc. and Bertelsmann are in talks to buy a minority stake in Polsat, one of Poland's three main television networks, Polish newspapers reported on Thursday.

Quoting two independent unnamed sources, Dziennik daily reported that Germany's Bertelsmann may have signed a preliminary agreement to buy a 20 percent share in Polsat at a cost of 250 million euros ($315 million).

Rival daily Gazeta Wyborcza said News Corp., run by R. Murdoch, was also in talks with the station.

Polsat could not immediately be reached for comment.

"I have signed no agreement though I do admit we are talking to Bertelsmann," Dziennik quoted Polsat owner Zbigniew Solorz as saying. "But we are also negotiating with other investors."

News Corp. last month bought a roughly 25 percent stake in small Polish terrestrial broadcaster TV Puls from its Franciscan brotherhood owners.

Polsat, which has two terrestrial stations as well as specialised pay channels, has sought a large media investor several times in recent years, without result.
