The air is getting thicker over at Liberty Media Corp. Liberty is seeking the ouster of IAC/InterActive Corp Chairman Barry Diller (pictured) from its board of directors in an escalating dispute over how to restructure the Internet conglomerate, legal filings showed on Monday. Liberty also wants to remove Diller’s wife, Diane Von Furstenberg, Edgar Bronfman Jr, Victor Kaufman, Arthur Martinez, Steven Rattner and Alan Spoon. Tensions between Diller and Liberty Chairman John Malone went public last week over a plan to spin off the HSN shopping network, Ticketmaster box office service, Interval time-share exchange and LendingTree morgage service from IAC. In a statement, IAC called the action “preposterous”.

The saga at Societe Generale, reeling from an alleged $7 billion fraud the banking giant said was committed by a lone rogue trader, has taken another twist. French prosecutors will not appeal a decision to throw out the accusation of fraud leveled against the trader, Jerome Kerviel, a senior judicial source said on Tuesday. This would be a blow for SocGen managers, because it is likely to spread the blame. Meanwhile, France’s economy minister, stating the obvious, said the bank is in crisis and may need to ditch its chairman. Really? Rival bank BNP Paribas may be getting giddy — speculation has reignited that France’s biggest listed lender might make a bid.
