Anthony Longden, managing editor of the group’s North and East London titles, left the company on Wednesday after six years.
He joined Newsquest from a similar role at Trinity Mirror Southern having previously spent 19 years working with South News.
Said Anthony: “There’s no mystery about the state of the economy and the pressure that is putting on local newspapers, and as a senior person in local newspapers I was painfully aware of that.
“I am parting company with Newsquest in good odour and I have thoroughly enjoyed my time there.”
During his time with the company Anthony was initially responsible for Newsquest Herts and Bucks before moving to his current role.
In 2009 he was involved in a long-running battle with Essex police over the Epping Forest Guardian’s refusal to sign an undertaking not to publish material “detrimental” to the force.
Anthony says he now plans to do some consultancy work.
