Redstone, 92, is the controlling shareholder of Viacom and CBS and his failing health in recent months has set off a power struggle between his family and associates, a source close to the matter told AFP today.
Philippe Dauman, chairman and CEO of MTV and Paramount Pictures parent company Viacom, received word in the middle of the week that he would be removed as a member of the National Amusements Inc Trust, the source said, confirming news reports and speaking on condition of anonymity due to the sensitivity of the matter.
The seven-member trust is meant to manage Redstone's empire in the event of his death or legal incapacity, and would have enormous power and influence over the future of Viacom and CBS.
The latest development was seen as a victory for Shari Redstone, Sumner Redstone's daughter, who is a member of the trust and vice president of both the CBS Board of Directors and Viacom.
Shari Redstone had openly opposed Dauman's appointment as chief of Viacom after her father stepped down.
Dauman has called his ouster "shameful" and "illegal," according to news reports.
"The picture is quite clear, Mr Redstone is being manipulated and used by his daughter in an attempt to accomplish her long-held goal, which Mr. Redstone has always opposed, of gaining control of National Amusements and Viacom," a Viacom spokesman said in a statement provided today to AFP, one day after Dauman and Abrams' removals were made official.
CBS did not immediately respond to a request for comment.
Media reports said Sumner Redstone was free to change or replace the members of his trust.
