New York Times: A 50% stake in The Economist Group, which includes CQ Roll Call, has been put up for sale by the education company Pearson, which recently sold the Financial Times to Nikkei of Japan. Pearson is said to be negotiating with the publication’s current shareholders, including Exor, the investment company controlled by the Agnelli family. Others who had coveted the publication have not been mentioned as contenders, perhaps because the company has a complex trust system that essentially ensures it cannot be taken over by an owner keen to impose his or her whims.
