U.S. Scripps Networks Interactive (SNI) (SNI.N), which agreed to buy control in TVN (TVN.WA), wants to call on other shareholders at the Polish broadcaster to sell it the remaining shares all at once, SNI was quoted as saying on Wednesday. SNI is awaiting regulatory approval for its March purchase of a 52.7 percent stake in TVN, one of Poland’s two largest private broadcasters, for 584 million euros ($654 million). It has said it wanted to buy all the remaining shares and delist TVN, but investors were not certain SNI would do it in one call.
