Murdoch is currently involved in a controversial bid to buy The Wall Street Journal. The board of parent company Dow Jones has backed the deal, which now awaits final approval from controlling shareholders. On Thursday, Dow board of directors member Dieter von Holtzbrinck announced his resignation over the board’s endorsement of the sale. In a statement, von Holtzbrinck said: “I’m very worried that Dow Jones unique journalistic values will long-term strongly suffer after the proposed sale.”
