WARSAW, Aug 14 (Reuters) - TV group Central European Media Enterprises <CETV.O><
> is among the bidders for a stake in Polish broadcaster Puls after Rupert Murdoch's News Corp <NWSA.O> pulled out last year, a source told Reuters on Friday."CME is among the bidders in negotiations to buy a stake in TV Puls," said a source close to the talks who asked not to be named.
CME, whose largest shareholder is Time Warner <TWX.N> after it bought a 31-percent stake earlier this year, declined to discuss its interest.
"As always, our policy is not to comment on speculations," said Romana Tomasova, vice-president, corporate communications.
The Bermuda-based company is present in seven central and east European countries, but has been absent from Poland, the region's largest economy, since pulling out of broadcaster TVN <TVNN.WA> a decade ago after falling out with local founders.
CME's shares rose as much as 3.4 percent in Prague trade and closed 1.7 percent higher. The stock fell 1.8 percent in New York after equity markets retreated on disappointing U.S. data.
Dariusz Dabski, the head of Puls and its second-largest shareholder, declined to confirm CME's interest. The station is controlled by the Franciscan order.
"I can only confirm that we are in talks with (Polish media company) Point Group (PMPG) <PEKP.WA>, which already revealed its participation, as well as other companies, also foreign groups," Dabski told Reuters.
The head of PMPG told Reuters that CME and Walt Disney Co. <DIS.N>, may be among parties interested in entering the Polish market with a controlling stake in Puls.
But a Walt Disney representative in London said the group was not pursuing Puls at the moment.
NEWS CORP'S SOURED INVESTMENT
News Corp invested more than $50 million in Puls only to give up its 35-percent stake last year when it failed to boost its weak ratings and take market share from private stations TVN and Polsat, and the public broadcaster.
Poland has seen its advertising market shrink by an estimated 16 percent to 1.8 billion zlotys in the first half of the year due to the global crisis, but its size and lack of large foreign players make it an attractive target for some of them.
Some market watchers speculate that TVN may also soon be in play after it dumped the son of one of the founders from the top post and replaced him with an industry insider from Murdoch's media empire on Thursday. [
