Tunku Varadarajan is stepping down as the editor of Newsweek Global. Adweek reports that Varadarajan is leaving to work on a book and spend time with his family. Varadarajan had been the editor of Newsweek International, and was tapped as the editor of the all digital format, Newsweek Global.

In a memo, Tina Brown said of Varadarajan, “We can all agree that he has done a stellar job as editor of the all-digital Newsweek, bringing the magazine so smartly into its new, exciting lease-of-life phase with his counterintuitive ideas, terrific cadre of writers week-after-week and the editorial collegiality that has made him such a pleasure to work with.”
