Former Guardian foreign correspondent Maggie O’Kane and music editor Michael Hann are among the latest high-profile journalists to leave the paper under an ongoing voluntary redundancy scheme.

Guardian and Observer NUJ father of chapel Brian Williams is also leaving the company, taking early retirement under the scheme. He has been with The Guardian for 27 years.

Press Gazette understands that Guardian News and Media is on course to hit a target of cutting 100 editorial jobs under a three-year cost-saving scheme which was launched just over a year ago.
