David had been in charge in Carlisle, where he was also responsible for the Cumberland News, since 2011, when he left the top job at Blackpool-based daily The Gazette to take up the post.
Chris Story will continue in his role as content editor at both the News & Star and the Cumberland News. It is not clear whether a new editor for the two titles will be appointed.
David’s departure was revealed in a memo sent to CN staff this morning by group chief executive Miller Hogg.
It reads: “I wanted to let you all know that unfortunately David Helliwell’s role as group editorial director has been made redundant and David has left the business with immediate effect.
“Our editorial teams will now ultimately report to Jonathan Lee, Group Development Director. Those individuals directly affected have been communicated with separately about their new reporting lines.
“David has been with CN for five years as CNL editor/deputy publishing director and latterly as group editorial director. In that time he has been a loyal employee and has amassed multiple editorial awards across the industry.
“I am sure you would like to join me in wishing David all the best with his future career and we would like to thank David for his input to CN Group.”
Last year he was involved in the launch of 24, CN’s ‘national newspaper for the north’, which closed after less than six weeks in print.
