Jo Elvin, who launched Glamour in the UK in 2001 and has been editing the magazine for 17 years, has decided to leave the magazine amid a decision from parent company Condé Nast to cut its print run to two issues a year and focus its attention online.
The magazine publisher said Elvin made the decision to step down from her role "in light of the ongoing developments with the Glamour brand", which has seen it implement a ‘mobile-first, social-first’ strategy and cut its reliance on print.
Elvin did not provide any insight into her next move beyond Glamour. Instead she said it has been an "honour" to be Glamour's editor for 17 years.
"The fact that I have stayed so long tells you a lot about what a fantastic title it is to lead and what an exceptional place Condé Nast has been to work," she said.
"I’m excited for what lies ahead, for both myself and for Glamour. I wish the new team every success for the exciting new phase of this wonderful, beloved brand," she added.
Condé Nast were not able to comment on plans to find Elvin's replacement until the statutory consultation period is underway.
Elvin began her career at teen magazine, Dolly, in Australia, and working as a publicist for sitcom Neighbours. In London she joined TV Hits magazine, before being tapped to launch youth titles, Sugar and B, and later becoming the editor of New Woman in 1998. In 2001, she launched Glamour magazine in the UK.
Albert Read, managing director of Condé Nast Britain, said Elvin's editorship, with its "forensic attention to quality, wit, inventiveness and fun", played a decisive role in the success of Glamour in the UK.
Nicholas Coleridge, chairman of Condé Nast Britain, called Elvin the "editor-to-beat" in her market for almost two decades, the "undisputed Queen of the upper-middle market".
