Guardian’s editor-in-chief Alan Rusbridger reveals raft of senior management changes across UK, US and Australia teams

Gibson will be replaced in the US by former editor-in-chief of Australia Katherine Viner, with both taking up their new roles this summer. Viner will be replaced in Australia by Emily Wilson, who is currently Network editor.

The restructure reflects the "radically-changing" ways that its journalism is produced, consumed and shared, and will ensure it stays at the "vanguard of innovation", according to Rusbridger.

The editor-in-chief notified staff of the changes last night in an email, in which he said: “It has been an extraordinary 12 months. The Guardian’s ground-breaking investigative journalism has dominated the news agenda around the world.

"There’s been the successful launch of Guardian Australia and our new global online home at theguardian.com; the tremendous acclaim around Guardian US; significant growth in digital revenues and online audiences alongside increased print circulation; and the sale of Auto Trader, which transformed GMG's balance sheet and should enable the Guardian to continue delivering world-class journalism for generations.

“Today I am announcing a series of changes that will not only build on these achievements but will also radically develop our video journalism and multimedia offering, bolster the Guardian’s intellectual heart, and further unlock the talents of some of our most talented journalists and editors.”

Deputy editor in the London office Paul Johnson, will be responsible for the “strategic position” of the print paper in the changing media landscape, according to Rusbridger, who added “print will remain a crucial part of what we do for the foreseeable future”.

Jonathan Freedland will become executive editor, Opinion, while Stuart Millar, currently deputy editor of Guardian US, will return to the UK as the Guardian’s overall head of news.
