Following the success of her guest edit in April, Jemima Khan will be joining the New Statesman as Associate Editor next month.
Her role will involve commissioning and writing for the magazine and working on specially curated issues. She will start on 14 November.
Khan's Free Speech special issue of the magazine on 11 April broke two agenda-setting stories - her own interview with Nick Clegg, in which he spoke candidly about the trials of being a hate figure, and Hugh Grant's undercover exposé of hacking at News of the World.
It featured further contributions from fine writers and fascinating public figures including Oliver Stone, Tim Robbins, Russell Brand, Simon Pegg, Rory Stewart, Alain de Botton and Jarvis Cocker, as well as a major 4,000-word investigation of brutality and corruption in the New Orleans law-enforcement system by the journalist James Fox.
The New Statesman's editor, Jason Cowley, said: "I'm delighted that Jemima is joining us and that I have tempted her away from the Independent. She worked brilliantly with the whole team on her guest-edited issue of the New Statesman.
"She is a first-rate journalist who has strong campaigning instincts and a powerful interest in international affairs and human rights issues. She's very popular among the staff."
Jemima Khan said: "I loved working on the guest edit at the beginning of the year and I am delighted to become a permanent part of the exceptional team at the New Statesman. I thoroughly enjoyed my time at the Independent but the challenge of a wider role at the New Statesman was too tempting."
