Janine Gibson, the Guardian US Editor, is returning to London to be Editor-in-Chief of the paper's website as part of a senior management restructure.

Gibson, who moved to New York in 2011 to launch the Guardian US digital operation and played a leading role in overseeing the paper's award-winning Edward Snowden revelations, will take up her new role as a Deputy Editor of Guardian News & Media and Editor-in-Chief of theguardian.com in the summer.
