Shari Redstone Weighs Bolting From Viacom

Viacom chairman Sumner Redstone is involved in a bitter spat with his daughter and heir apparent, Shari Redstone, that may lead to her splitting from the Viacom board. Negotiations for her separation from the media empire that counts CBS, MTV, and Paramount among its many holdings are under way, the Wall Street Journal reports.

A spokeswoman for Shari Redstone denied the report, telling Reuters she "has no intention of resigning and has not been asked to resign" from the Viacom and CBS boards. With son Brent also out of the picture, it is unclear who will succeed 84-year-old Sumner Redstone. TheStreet.com reports that the uncertainty boosted Viacom stock because it may foretell a sale.
