Guardian: Katharine Viner has been appointed the editor-in-chief of the Guardian, the first woman to run the U.K. newspaper in its 194-year history. Viner, currently deputy editor of the Guardian and editor-in-chief of Guardian U.S., will take up the role in the summer from incumbent Alan Rusbridger, who is to stand down after 20 years. Viner will become only the 12th editor since the paper was founded in May 1821.
