Alan Rusbridger, who has been Editor-in-Chief of The Guardian for 20 years, is to step down from the position next summer to join the Scott Trust as chair in 2016.

Rusbridger and the paper have won a number of awards during his time as Editor, including the Pulitzer Prize for public service for its articles on the National Security Agency's surveillance activities based on the leaks of Edward Snowden earlier this year. He commented 'In global journalism, there are a handful of roles that have the capability to redefine our industry. I am privileged to have held one of those roles for 20 years, a period in which successful newspapers have become global content providers, reaching audiences in dramatically new and valuable ways'.
